A woman is selected at random from the population of the United States. Let event A represent "The woman is a professional basketball player" and event B represent "The woman is taller than 5 feet 4 inches."

Are these probabilities equal? If so, explain your reasoning. If not, explain which one is the greatest and why.

P(B) when you have no other information.

P(B) when you know A is true.

P(B) when you know A is false.

Answers

The probability of event B would likely be greater when event A is true, reflecting the tendency of professional basketball players to be taller.

To determine the probabilities in question, we need to consider the information provided and make some assumptions based on general knowledge about the population of the United States.

P(B) when you have no other information:

Without any other information, we cannot accurately determine the probability of event B, which represents "The woman is taller than 5 feet 4 inches." We would need additional data on the height distribution of women in the United States to calculate this probability.

P(B) when you know A is true:

If we know that event A is true, meaning "The woman is a professional basketball player," we can make some assumptions based on the nature of professional basketball players.

Generally, professional basketball players tend to be taller than the average population due to the physical requirements of the sport. Therefore, the probability of event B, "The woman is taller than 5 feet 4 inches," would likely be greater when we know event A is true.

P(B) when you know A is false:

If event A is false, meaning "The woman is not a professional basketball player," we cannot make any definitive conclusions about the probability of event B, "The woman is taller than 5 feet 4 inches." The height of an individual is not solely determined by their profession, so without further information, we cannot determine if event B is more or less likely when event A is false.

In summary, based on the given information, we can conclude that the probabilities of event B are not equal under different scenarios. The probability of event B would likely be greater when event A is true, reflecting the tendency of professional basketball players to be taller. However, without any other information, we cannot determine the probability of event B or make comparisons when event A is false.

Round your answer to two decimal places. 43 15 Mathematics 29 35 Computer science 20 36​

Answers

To find the relative frequency of biology majors in the sample, we need to divide the number of biology majors by the total number of students in the sample.

The contingency table shows that there are 47 female biology majors and 36 male biology majors, resulting in a total of 47 + 36 = 83 biology majors in the sample.

The total number of students in the sample is 318.

To calculate the relative frequency, we divide the number of biology majors (83) by the total number of students (318):

Relative frequency of biology majors = 83 / 318 ≈ 0.26

Rounded to two decimal places, the relative frequency of biology majors in the sample is approximately 0.26 or 26%.

The box contains some green and yellow counters. 7/4 of the box is green counters. There are 24 yellow counters . How many green counters are there?

Answers

Considering the definition of an equation and the way to solve it, there are 84 green counters in the box.

Definition of equation

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.

Amount of green counters

Knowing that:

7/9 of the box is green counters.1-7/9= 2/9 of the bok are yellow counters.There are 24 yellow counters.

the equation in this case is:

2/9 × total counters on the box =24

Solving:

total counters on the box =24÷ 2/9

The first step in dividing by a fraction is to find the reciprocal (reverse the numerator and denominator) of the second fraction.

Then, the two numerators and the two denominators must be multiplied and, if necessary, the fractions are simplified.

total mountain bikes =24× 9/2= 24/1× 9/2

total mountain bikes =(24×9)/ (1×2)

total mountain bikes =216/2

total mountain bikes =108

Then, there are 108 green and yellow counters in the box.

So, the amount of green counters in the box is calculated as:

Amount of green counters= 7/9× 108

Amount of green counters= 7/9× 108

Amount of green counters= 84

Finally, there are 84 green counters in the box.

a) Su-Lo scored 45% in her test out of 80.
what mark did she
score?

Answers

Answer:

Step-by-step explanation:

To calculate Su-Lo's score on the test, we can multiply her percentage by the total marks for the test.

Su-Lo scored 45% out of 80, so her score can be calculated as follows:

Score = Percentage × Total marks

Score = 45% × 80

To find the score, we need to convert the percentage to a decimal by dividing it by 100:

Score = (45/100) × 80

Score = 0.45 × 80

Score = 36

Therefore, Su-Lo scored 36 marks on the test.

two rectangles have the same base lengths. one rectangle has a height that is twice the height of the other rectangle. are the heights and areas proportional

Answers

Although the rectangles have the same base lengths, the heights and areas are not directly proportional in this case.

Are the heights and areas of the rectangles proportional?

Let's denote the base length of both rectangles as 'b'. If one rectangle has a height that is twice the height of the other rectangle, we can denote the heights as 'h' and '2h', respectively.

The area of a rectangle is calculated by multiplying the base length by the height. Therefore, the area of the first rectangle with height 'h' would be A₁ = b * h, and the area of the second rectangle with height '2h' would be A₂ = b * (2h) = 2b * h.

Comparing the two areas, we have A₁ = b * h and A₂ = 2b * h. It is evident that the areas are not proportional because the area of the second rectangle is twice the area of the first rectangle.

P(-1; -1) S(-3; -7) Q(4; 2) R(7; -5) Determine (correct to one decimal place): 3.2 3.1 the acute angle between QR and the x-axis the angle of inclination of PQ POR 3.3 3.4 the angle of inclination of SP 3.5 SPR 3.6 PSR.​

Answers

To determine the requested angles, we can use trigonometry and geometry principles:

1. Acute angle between QR and the x-axis:

The angle between QR and the x-axis can be found by calculating the arctan of the slope of QR. The slope (m) can be found using the formula: m = (y2 - y1) / (x2 - x1).

Given points Q(4, 2) and R(7, -5):
m(QR) = (-5 - 2) / (7 - 4) = -7/3

Using the arctan function, we can find the acute angle (A1):
A1 = arctan(-7/3) ≈ -68.2 degrees

2. Angle of inclination of PQ:

The angle of inclination of PQ can be found using the same method as above with points P(-1, -1) and Q(4, 2):
m(PQ) = (2 - (-1)) / (4 - (-1)) = 3/5

The angle of inclination (A2) can be found by taking the arctan of the slope:
A2 = arctan(3/5) ≈ 30.96 degrees

3. Angle of inclination of POR:

The angle of inclination of POR can be found using points P(-1, -1) and R(7, -5):
m(POR) = (-5 - (-1)) / (7 - (-1)) = -6/8 = -3/4 = -0.75

The angle of inclination (A3) can be found using the arctan function:
A3 = arctan(-0.75) ≈ -36.87 degrees

4. Angle of inclination of SP:

To find the angle of inclination of SP, we can use points S(-3, -7) and P(-1, -1):
m(SP) = (-1 - (-7)) / (-1 - (-3)) = 6/2 = 3

The angle of inclination (A4) can be found using the arctan function:
A4 = arctan(3) ≈ 71.57 degrees

5. Angle SPR:

To find angle SPR, we can use the Law of Cosines. Using the distance formula, we can find the lengths of sides SP, SR, and PR. Let's denote SP as a, SR as b, and PR as c:

a = sqrt((-3 - (-1))^2 + (-7 - (-1))^2) = sqrt(4^2 + 6^2) = sqrt(52) ≈ 7.21
b = sqrt((-3 - 7)^2 + (-7 - (-5))^2) = sqrt(10^2 + 2^2) = sqrt(104) ≈ 10.2
c = sqrt((-1 - 7)^2 + (-1 - (-5))^2) = sqrt((-8)^2 + 4^2) = sqrt(80) ≈ 8.94

Now we can apply the Law of Cosines to find the angle SPR (A5):
cos(A5) = (a^2 + b^2 - c^2) / (2ab)
A5 = arccos((7.21^2 + 10.2^2 - 8.94^2) / (2 * 7.21 * 10.2)) ≈ 42.1 degrees

6. Angle PSR:

To find angle PSR, we can subtract the angle SPR (A5) from the angle of inclination of SP (A

Jonah's swimming pool is 21 meters by 20 meters. He swam from one corner of the pool to the opposite corner. How far did Jonah swim?

Answers

Jonah swam a distance of 29 meters from one corner of the pool to the opposite corner.

To determine how far Jonah swam from one corner of the pool to the opposite corner, we can use the Pythagorean theorem. According to the theorem, in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.

In this case, the two sides of the right-angled triangle are the length and width of the swimming pool, which are 21 meters and 20 meters respectively. The distance Jonah swam represents the hypotenuse of the triangle.

Using the Pythagorean theorem:

[tex]Hypotenuse^2 = Length^2 + Width^2[/tex]

[tex]Hypotenuse^2[/tex] =[tex]21^2 + 20^2[/tex]

[tex]Hypotenuse^2[/tex]= 441 + 400

[tex]Hypotenuse^2[/tex]= 841

Taking the square root of both sides, we find:

Hypotenuse =[tex]\sqrt{841[/tex]

Hypotenuse = 29

Solve (D ^ 2 - 6D + 9) * y = 0

Answers

The solution to the given differential equation is y(x) = (C1 + C2x) * e^(3x), where C1 and C2 are arbitrary constants.

To solve the given differential equation, we need to find the function y(x) that satisfies the equation:

(D^2 - 6D + 9)y(x) = 0,

where D represents the differentiation operator.

Let's break down the solution process step by step:

Characteristic Equation

First, we'll find the characteristic equation associated with the given differential equation. For a second-order linear homogeneous differential equation of the form aD^2y + bDy + cy = 0, the characteristic equation is obtained by replacing D with λ:

λ^2 - 6λ + 9 = 0.

Solving the Characteristic Equation

Now, we solve the characteristic equation to find the values of λ. Factoring the equation, we get:

(λ - 3)^2 = 0.

From this, we see that λ = 3 (with a multiplicity of 2).

General Solution

The general solution of the differential equation is given by:

y(x) = C1e^(λ1x) + C2xe^(λ2*x),

where C1 and C2 are arbitrary constants, and λ1, λ2 are the distinct roots of the characteristic equation.

In our case, since we have repeated roots, the general solution simplifies to:

y(x) = C1e^(3x) + C2xe^(3*x).

Answers

The nearest Whole number, the missing dimension (height) of the cylinder is approximately 39 inches.

The missing dimension of the cylinder, we can use the formula for the volume of a cylinder:

Volume = π * r^2 * h

Given that the volume is 10,000π in³ and the diameter of the base is 32 inches, we can determine the radius (r) of the cylinder.

The diameter is twice the radius, so the radius is half of the diameter:

r = 32 inches / 2 = 16 inches

Substituting the known values into the volume formula, we have:

10,000π in³ = π * (16 in)^2 * h

Cancelling out the common factor of π, we get:

10,000 = 16^2 * h

Simplifying further:

10,000 = 256 * h

To isolate h, we divide both sides of the equation by 256:

h = 10,000 / 256

Calculating the value of h:

h ≈ 39.06

Rounded to the nearest whole number, the missing dimension (height) of the cylinder is approximately 39 inches.

Answers

This equation represents the value of the stock, V(t), in dollars, t years after 1940, taking into account the 7% annual Growth rate V(t) = $1.25 * (1 + 0.07)^t.

The value of the stock, V(t), in dollars, t years after 1940, we can use an exponential growth equation since the stock's value grows by 7% each year after 1940.

formulate the equation step by step:

1. We know that the initial value of the stock in 1940 is $1.25. This initial value serves as the starting point for our equation.

2.We are given that the value of the stock grows by 7% each year. This means that for every year that passes, the stock's value increases by 7% of its previous value.

3. In mathematical terms, if V(0) represents the initial value in 1940 ($1.25), then the value of the stock after t years can be represented as:

V(t) = V(0) * (1 + r)^t,

where r is the growth rate expressed as a decimal (in this case, 7% = 0.07).

4. Plugging in the given values, our equation becomes:

V(t) = $1.25 * (1 + 0.07)^t.

This equation represents the value of the stock, V(t), in dollars, t years after 1940, taking into account the 7% annual growth rate.

For example, if we wanted to find the value of the stock 10 years after 1940, we would substitute t = 10 into the equation:

Substituting the values of h, k, and p into the equation, we get:

[tex](y - 4)^2 = 4(-2)(x - 2)[/tex]

Simplifying further:

[tex](y - 4)^2 = -8(x - 2)[/tex]

Answer:

Mr Kalada's present age is 45 years old

Step-by-step explanation:

You empty a 2-liter bottle every 8 seconds into tanks that hold 50 gallons. How long will it take you to fill 11 tanks? (3.8 l = 1 gallon)(Convert 11 tanks to hours)

Answers

It will take approximately 2.32 hours to fill 11 tanks.

First, we need to convert the capacity of the tanks from gallons to liters, as the rate at which we empty the bottle is given in liters. Since 1 gallon is equal to 3.8 liters, the capacity of each tank is 50 gallons * 3.8 liters/gallon = 190 liters.

Now, let's calculate the time it takes to fill one tank:

The bottle is emptied at a rate of 2 liters every 8 seconds. To find the time it takes to fill one tank, we divide the capacity of the tank (190 liters) by the rate at which we empty the bottle (2 liters/8 seconds):

Time for one tank = 190 liters / (2 liters/8 seconds) = 190 liters * (8 seconds/2 liters) = 760 seconds.

Next, we need to find the total time required to fill 11 tanks. Since each tank takes 760 seconds to fill, we multiply this by 11 to account for the 11 tanks:

Total time to fill 11 tanks = 760 seconds/tank * 11 tanks = 8,360 seconds.

Finally, we convert the total time from seconds to hours. There are 60 seconds in a minute and 60 minutes in an hour, so:

Total time to fill 11 tanks = 8,360 seconds * (1 minute/60 seconds) * (1 hour/60 minutes) = 2.32 hours (rounded to two decimal places).

Therefore, it will take approximately 2.32 hours to fill 11 tanks.

What is the area of a trapezoid with bases that are 7 meters and 10 meters in length and a height of 12 meters? 42 m2 60 m2 102 m2 204 m2

Answers

The area of a trapezoid is given by the formula:

A = (b1 + b2) * h / 2

where b1 and b2 are the lengths of the two bases, and h is the height.

Plugging in the values given in the problem, we get:

A = (7 + 10) * 12 / 2
= 17 * 6
= 102

Therefore, the area of the trapezoid is 102 square meters. Answer: 102 m2.

The value of the given expression:

⇒ mk = 12

⇒ m + k = 8  

The given values,

m = 6

k  = 2

We have evaluate the given expression,

mk

This is nothing but product of m and k

Since we know,

The product is the result of multiplying two or more numbers together. Assume they are two integers and, then their product is derived by multiplying both numbers together.

Therefore,

⇒ mk = 6x2

⇒ mk = 12

We have evaluate the given expression,

m + k

This is nothing but addition of m and k

Since we know that,

Addition is the process of joining two or more integers. The numbers being added are known as addends, and the result or final response obtained after the procedure is known as the total.

⇒ m + k = 6 + 2

⇒ m + k = 8

The equation of the parabola with the given focus (2, 7) and directrix y = -1 is [tex](x - 2)^2 = 12(y - 3)^2[/tex].Option C.

To find the equation of the parabola with a focus and directrix, we can use the standard form of the equation of a parabola:

For a vertical parabola:

[tex](x - h)^2 = 4p(y - k),[/tex]

where (h, k) is the vertex, and p is the distance from the vertex to the focus and directrix.

In this case, the focus is given as (2, 7), which means the vertex is also (2, 7) since the focus and vertex lie on the axis of symmetry. Additionally, the directrix is given as y = -1, which means the directrix is a horizontal line.

First, let's determine the distance from the vertex to the focus and directrix, which is the value of p. The distance is the absolute difference between the y-coordinate of the focus (7) and the y-coordinate of the directrix (-1):

p = |7 - (-1)| = 8.

Now we can substitute the values of the vertex (h, k) = (2, 7) and p = 8 into the standard form equation:

[tex](x - 2)^2 = 4(8)(y - 7).[/tex]

Simplifying further:

[tex](x - 2)^2 = 32(y - 7).[/tex]

Expanding the equation:

[tex]x^2 - 4x + 4 = 32y - 224.[/tex]

Rearranging the terms:

[tex]x^2 - 4x - 32y + 228 = 0.[/tex]

Therefore, the equation of the parabola with the given focus (2, 7) and directrix y = -1 is  [tex](x - 2)^2 = 12(y - 3)^2.[/tex] SO Option C is correct.
