The probability that both grab oranges would be = 1/30

Step-by-step explanation:

bc 1/8 * 2/9 = 1/30

hope this helps

Answer: The probability that both grab oranges would be =1/36

Step-by-step explanation:

Given,

A bowl contains,

Apples = a = 5

Oranges = o = 2

bananas = b = 2

Total fruits in bowl = x = a + o + b = 5 + 2 + 2 = 9

Now, Christian and Aaron come home from school and randomly grab one fruit each.

The probability of first selecting orange would be = o/b =2/9

Now, the oranges left would be 2 - 1 = 1

and total fruits would be = 9 - 1 = 8

Hence, the probability of selecting second orange would be = 1/8

Therefore, the probability that both grab oranges would be = 1/8 2/9 =1/36

A scatter plot of the data is shown below.

An equation of a reasonable trend line is y = x - 0.1.

The arm span of someone who is 1.6 m tall is 1.5 meter.

The arm span of someone who is 2.2 m tall is 2.1 meters.

In order to write a linear equation for the line of best fit (trend line) that models the data points contained in the table, we would have to use a graphing calculator (scatter plot).

In this scenario, the heights would be plotted on the x-axis of the scatter plot while the arm span would be plotted on the y-axis of the scatter plot.

At point (2.0, 1.9), an equation of this line can be calculated by using the point-slope form:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 1.9 = (2.0 - 1.9)/(2.1 - 2.0)(x - 2.0)

y - 1.9 = (x - 2.0)

y = x - 0.1.

For someone who is 1.6 m tall, their arm span is given by;

y = x - 0.1

y = 1.6 - 0.1.

x = 1.5 meter.

For someone who is 2.2 m tall, their arm span is given by;

y = x - 0.1

y = 2.2 - 0.1.

x = 2.1 meters.

The p-value is 0.1138 for the given hypothesis.

What exactly is a p-value?

A p-value, or probability value, is a statistical measure that helps to determine the strength of evidence against a null hypothesis in a hypothesis test. In hypothesis testing, a null hypothesis is a statement or assumption about a population parameter that we want to test using sample data. The p-value is the probability of obtaining a test statistic as extreme as, or more extreme than, the observed test statistic, assuming the null hypothesis is true.

Now,

To test the hypothesis,

 we need to perform a hypothesis test using a significance level (α) to determine whether the sample proportion of satisfied customers is significantly different from 0.9.

The null hypothesis (H0) is that the true proportion of satisfied customers is equal to 0.9. The alternative hypothesis (H1) is that the true proportion is not equal to 0.9.

We can use the normal approximation to the binomial distribution to test this hypothesis, since the sample size is large (n = 1000) and both np and n(1-p) are greater than or equal to 10, where p is the true proportion of satisfied customers.

The test statistic is given by:

z = (P - p0) / √(p0(1 - p0) / n)

where p0 is the proportion (0.9), P is the sample proportion (850/1000 = 0.85), and n is the sample size.

Plugging in the values, we get:

z = (0.85 - 0.9) / √(0.9 * 0.1 / 1000) = -1.5811

The P-value is the probability of getting a test statistic as extreme as -1.5811 or more extreme, assuming the null hypothesis is true. Since this is a two-tailed test (H1: p ≠ 0.9), we need to find the area in both tails of the standard normal distribution.

Using a standard normal distribution table, we find that the area to the left of -1.5811 is 0.0569, and the area to the right of 1.5811 is also 0.0569. Therefore, the total area in both tails is:

p-value = 0.0569 + 0.0569 = 0.1138

So,

     the p-value is 0.1138.

Answer: Let's call the number of large boxes purchased "L" and the number of small boxes purchased "S".

From the problem, we know that:

Each small box has 100 nails, so the total number of nails from the small boxes is 100S.

Each large box has 450 nails, so the total number of nails from the large boxes is 450L.

The contractor bought 3 more small boxes than large boxes, so S = L + 3.

The total number of nails purchased is 2500, so 100S + 450L = 2500.

We can use the second equation to solve for one of the variables in terms of the other. For example, we can solve for L:

100S + 450L = 2500

Substituting S = L + 3:

100(L + 3) + 450L = 2500

Expanding the parentheses:

100L + 300 + 450L = 2500

Combining like terms:

550L + 300 = 2500

Subtracting 300 from both sides:

550L = 2200

Dividing both sides by 550:

L = 4

So the contractor purchased 4 large boxes of nails.

We can use the equation S = L + 3 to find the number of small boxes purchased:

S = L + 3 = 4 + 3 = 7

So the contractor purchased 7 small boxes of nails.

Therefore, the contractor purchased 4 large boxes and 7 small boxes of nails.

Step-by-step explanation:

The equations that can be used to find the number of students in the homeroom are:

4 = 20 - 1/2m

1/2m + 4 = 20

An equation is a statement that expresses the equality of two expressions in mathematics. It is two expressions that are connected by an equals to sign.

4 + 1/2m = 20

Where m is the number of students in Bryan's home room

In order to determine the value of m, take the following steps:

Combine similar terms:

1/2m = 20 - 4

Add similar terms

1/2m = 16

Multiply both sides of the equation by 2

m = 16 x 2

m = 32

The volume of the rectangular prism is 60 cubic feet.

What is a rectangular prism?

A rectangular prism is a three-dimensional geometric shape with six faces, where each face is a rectangle. It is also known as a rectangular cuboid. A rectangular prism has 8 vertices, 12 edges, and 6 rectangular faces. The opposite faces of a rectangular prism are congruent and parallel to each other. The length (l), width (w), and height (h) of a rectangular prism are the three dimensions that determine its size and shape.

The formula for the surface area of a rectangular prism is:

SA = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the prism, respectively.

In this case, we have l = r, b = 5ft, h = 3ft, and SA = 94 sq ft. Substituting these values into the formula, we get:

94 = 2(r)(5) + 2(r)(3) + 2(5)(3)

94 = 10r + 6r + 30

94 = 16r + 30

64 = 16r

r = 4

So, the length of the rectangular prism is 4 feet.

Now, we can use the formula for the volume of a rectangular prism:

V = lwh

Substituting the values for l, w, and h, we get:

V = (4)(5)(3) = 60 cubic feet

Therefore, the volume of the rectangular prism is 60 cubic feet.

Ruben ordered 0 boxes of cards and Estelle ordered 2 boxes of cards. Ruben spent $8 and Estelle spent $20 + $6(2) = $32.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's start by setting up equations for the total cost of Ruben and Estelle's business cards. Let R be the number of boxes of cards Ruben ordered and E be the number of boxes Estelle ordered. Then we have:

Ruben's cost = 8 + 18R

Estelle's cost = 6E + 20

We know that Ruben and Estelle spent the same amount, so we can set their costs equal to each other and solve for R and E:

8 + 18R = 6E + 20

18R - 6E = 12

3R - E = 2

This equation tells us that Ruben ordered two more boxes of cards than Estelle. We can use trial and error to find the values of R and E that satisfy this equation and give us the same cost:

If R = 4 and E = 2, then Ruben's cost = 8 + 18(4) = 80 and Estelle's cost = 6(2) + 20 = 32, which are not equal.

If R = 3 and E = 1, then Ruben's cost = 8 + 18(3) = 62 and Estelle's cost = 6(1) + 20 = 26, which are not equal.

If R = 2 and E = 0, then Ruben's cost = 8 + 18(2) = 44 and Estelle's cost = 6(0) + 20 = 20, which are not equal.

If R = 1 and E = -1, then Ruben's cost = 8 + 18(1) = 26 and Estelle's cost = 6(-1) + 20 = 14, which are not equal.

If R = 0 and E = -2, then Ruben's cost = 8 + 18(0) = 8 and Estelle's cost = 6(-2) + 20 = 8, which are equal.

Therefore, Ruben ordered 0 boxes of cards and Estelle ordered 2 boxes of cards. Ruben spent $8 and Estelle spent $20 + $6(2) = $32.

The function representing the daily profit based on production of premium coffee is given by ,

T = [tex]\int_{1}^{x}[/tex]  [(t² + 1 ) / t² ] dt +  (13,500 + (1/x) - x)

Function for daily profit associated with the production of excel so coffee is equal to,

G(x) =[tex]\int_{1}^{x}[/tex]  [(t² + 1 ) / t² ] dt

Let's assume that the profit per kilogram of premium coffee is p dollars.

And total production of premium coffee is y kilograms per day.

Total profit from premium coffee is P = p × y

Company produces a total of 4000 kilograms of coffee per day.

⇒ y = 4000 - x

x = production of traditional coffee in kilograms per day.

Total profit for the company is,

T = G(x) + P

Substituting the expressions for P and y,

T = G(x) + p × (4000 - x)

Company's daily profit from producing traditional coffee =  $13,500

⇒ 13,500 = G(x) + 4 × x

Substituted the marginal profit of $4 per kilogram for traditional coffee.

Profit per kilogram of premium coffee, p, in terms of x is equal to,

⇒ T = G(x) + p × (4000 - x)

⇒ 13,500 = G(x) + p×(4000 - x)

⇒ 13,500 =    [tex]\int_{1}^{x}[/tex][(t² + 1 ) / t² ] dt + p×(4000 - x)

⇒ 13,500 = [x - (1/x)] + p× (4000 - x)

⇒13,500 = x - (1/x) + 4000p - px

⇒ 13,500 = (1-p)x - (1/x) + 4000p

p = (13,500 + (1/x) - x)/(4000 - x)

Function for daily profit associated with the production of premium coffee is,

T = G(x) + (13,500 + (1/x) - x)/(4000 - x) × (4000 - x )

Simplifying we get,

⇒ T = G(x) + (13,500 + (1/x) - x)

Therefore, the function for daily profit associated with the production of premium coffee is equal to

T = [tex]\int_{1}^{x}[/tex]  [(t² + 1 ) / t² ] dt +  (13,500 + (1/x) - x)

After using the formula of a trapezoid, we know that the area is 25 units².

The size of a patch on a surface is determined by its area.

Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

The shape can also be placed on a grid, and the number of squares can be counted: The area of the rectangle is 15.

For instance, if each square is 1 meter in size, the area is 15 m² (15 square meters).

So, we  have the vertices as follows:

A(−3, 2), B(2, 2), C(2, −4), and D(−3, −2)

We can say that after answering the offered question The ladder is Pythagorean theorem therefore 15 feet long, rounded up to the next foot. Thus, 15 feet is the solution.

The Pythagorean Theorem is the foundational Euclidean geometry connection that exists between the three sides of the right triangle. According to this rule, the area of either a cube with the length x side is equal to the total of the regions of triangles shared by its other two sides. According to the Pythagorean Theorem, the square that spans the hypotenuse of a right triangle opposite the perfect angle is the combined squares that spanned its sides. It is sometimes expressed as a2 + b2 = c2 in general algebraic notation.

The ladder serves as the hypotenuse in this basic example of a right triangle, which also includes the distance from the house as one of its legs and the ladder's height as its second leg. The Pythagorean theorem can be used to find the ladder's length.

[tex]c^2 = a^2 + b^2[/tex]

In this instance, we know that the distance from the house (a) is 9 feet, and the height of the ladder (b) is 12 feet. Hence, we can enter these values into the formula as follows:

[tex]c^2 = 9^2 + 12^2 c^2 = 81 + 144\sc^2 = 225\sc = √225\sc = 15[/tex]

The triangle is acute since a² + b² < c² ( 2916 + 961  < 4761.

To determine whether the triangle is right, acute, or obtuse, we can use the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.

We can start by finding the longest side of the triangle, which is the hypotenuse.

hypotenuse = 69

Now we can use the Pythagorean Theorem to check whether the triangle is right:

a² + b² = c²

where a and b are the lengths of the other two sides of the triangle.

Plugging in the values we know, we get:

54² + 31² = 69²

Simplifying, we get:

2916 + 961 = 4761

3877 = 4761

Since this equation is not true, we know that the triangle is not a right triangle.

To determine whether the triangle is acute or obtuse, we need to compare the sum of the squares of the lengths of the shorter sides to the square of the length of the longest side:

a² + b² < c² => the triangle is acute

a² + b² > c² => the triangle is obtuse

c² = 69² = 4761

Plugging in the values we know, we get:

54² + 31² = 2916 + 961 = 3877

Since 3877 < 4761, we can conclude that the triangle is acute.
