Event 1:

Likelihood of choosing a black marble from bag A = 11/20 = 0.55

Event 2:

Likelihood of choosing a black or green marble from bag A = 11/20 + 9/20

Likelihood of choosing a black or green marble from bag A = 0.55 + 0.45

Likelihood of choosing a black or green marble from bag A = 1

Event 3:

Likelihood of choosing a balck marble from bag B = 8/10 = 0.8

Answer:

y = w/(h - 5c^3)

Step-by-step explanation:

w = yh - 5yc^3

factorise out y:

w = y(h - 5c^3)

rearrange:

y = w/(h - 5c^3)

I think this is correct.

Updated Probabilities are: P(L1/W) = 0.341 & P(L1/w) = 0.949

Let W be the event that the robot's camera observes a window

It is given that the Probability of observing a window there is no window at its location is given 0.2

P(W/ L1) = 0.2 ( L1 which does not have a window)

Also, probability of observing a window is 0.9

P(W/ L2) = 0.9 ( L2 has window)

Now we have to find updated probabilities for the robot being in L1 i.e:- P(L1/W) & P(L1/w)

w means the camera does not observe a window.

By Bayes Rule,

P(L1/W) = P(L1)P(W/L1)/P(L1)P(W/L1)+P(L2)P(W/L2)

            = (0.7x 0.2)/ (0.7x0.2) + (0.3x0.9)

            = (0.14)/ 0.14+0.27

            ≈0.341 (rounded to 3. decimal places)

Thus  the probability of being in L1 if the camera observes a window is nearly 0.341.

P(L1/w) = P(L1)P(w/L1)/P(L1)P(w/L1)+P(L2)P(w/L2)

As P(W/L1) = 0.2;

P(w/L1) = 1 - P(w/L1) = 1-0.2 = 0.8

Also P(W/L2) = 0.1;

P(w/L2) = 1 - P(w/L2) = 1-0.9 = 0.1

P(L1/w) = (0.7 X 0.8)/ (0.7X0.8) + (0.3X0.1)

           =(0.56)/ (0.56+0.03) = (0.56/ 0.59)

           ≈ 0.949 (rounded to 3 decimal places).

Thus the probability of being in L1 if observe not the window is nearly 0.949.

Updated Probabilities are: P(L1/W) = 0.341 & P(L1/w) = 0.949

The measure of angle R is 60°.

The lengths of side RS are RS₁ = 256 and RS₂ = 16.

The lengths of side RT are RT₁ = 256 and RT₂ = 16.

In this problem we need to find the values of four variables related to a triangle, which is seen in the picture, indicating an equilateral triangle. The solution of this question must be done by using definitions and theorems from Euclidean geometry:

Value of variable x

According to Euclidean geometry, the measures of the three sides in an equilateral triangle are the same. Then, the variable x can be found by solving the following equation:

RT = RS

x² = 12 · x + 64

x² - 12 · x - 64 = 0

(x - 16) · (x + 4) = 0

There are two possible solutions:

x₁ = 16, x₂ = - 4

Measure of the angle R

Equilateral triangles have three internal angles of 60°. Therefore, m ∠ R = 60°.

Length of side RS

There are two options:

RS₁ = 16²

RS₁ = 256

RS₂ = (- 4)²

RS₂ = 16

Length of side RT

There are two options:

RT₁ = 12 · 16 + 64

RT₁ = 256

RT₂ = 12 · (- 4) + 64

RT₂ = 16

We are given the following expression:

To determine the quotient of the expression we will factor the numerator. To do that we take the Greatest Common Multiple of the denominator.

The denominator is the following expression:

To get the greatest common multiple we need to determine the multiples of the coefficients first.

For 15 we have:

For 30 we have:

For 45 we have:

We notice that the factors that are repeated for each of the numbers are:

The greatest of the repeated factors is 15, therefore, the greatest common factor is 15.

Now, we take the variables that are repeated in the expression and we take the ones with smaller exponents. The variables repeated are:

Of these, the ones with smaller exponents are:

Now, combining the two parts we get that the greatest common factor of the denominator is:

We take out that factor and re arrange the expression, like this:

Now, we cancel out the "xy" and simplify 15/5:

And thus we get the quotient.

We notice that the quotient is multiplied by 3, therefore, if we divide by 3:

We can cancel out the 3 and we get:

Therefore, the quotient is divided by 3.

Equation y (1/8 x3 + 7) is rewritten by using a common factor. A literal equation is regarded as having at least two variables.

We have the next inequality

where x is the number of miles.

Then we solve the inequality

The car should be driven 300 miles a week

Answer:

x = -55

Step-by-step explanation:

Given equation,

→ 5(2 - x) - 10 = 25 - 2(3x + 40)

Now the value of x will be,

→ 5(2 - x) - 10 = 25 - 2(3x + 40)

→ 10 - 5x - 10 = 25 - 6x - 80

→ -5x + 6x = 25 - 80

→ [ x = -55 ]

Hence, the value of x is -55.

Answer:

x = -55

Step-by-step explanation:

Given equation,

→ 5(2 - x) - 10 = 25 - 2(3x + 40)

Now the value of x will be,

→ 5(2 - x) - 10 = 25 - 2(3x + 40)

→ 10 - 5x - 10 = 25 - 6x - 80

→ -5x + 6x = 25 - 80

→ [ x = -55 ]

Hence, the value of x is -55.

1. The mathematical expression for the length is C. 2x + 5.

2. The quadratic equation is A. 2x² + 5x - 18 = 0.

3. The width of the tarpaulin is A. 2 ft.

4. The length of the tarpaulin is D. 9 ft.

5. The perimeter of the tarpaulin is C. 22 feet.

From the information, the following can be deduced:

Width = x

Length = (2 × x) + 5 = 2x + 5

Area = 18 ft²

The equation will be:

Length × Width =Area

(2x + 5)x = 18

2x² + 5x = 18

2x² + 5x - 18 = 0

2x² - 4x + 9x - 18 = 0

2x(x - 2) + 9(x - 2)

Therefore, x - 2 = 0

x = 0 + 2 = 2

Width = 2

Length = 2x + 5 = 2(2) + 5 = 9ft

Perimeter = 2( Length + Width)

= 2(2 + 9)

= 22 feet.

This illustrates the concept of addition to calculate the perimeter.

Elijah put $53 in the Bank in the first week .

In the question ,

it is given that Elijah put (2x+3) in the first week .

In the second week Elijah put double the first week savings

that means second week deposit = 2*(2x+3) = 4x+6

in the third week he doubled the amount that was in the bank ,

which means third week deposit = 2*(first week + second week deposit)

= 2*(2x+3+4x+6)

Also given that total amount in the bank = $477

total amount = first week + second week + third week deposit

substituting the values we get

477 = (2x+3) + (4x+6) + 2*(2x+3+4x+6)

477 = 2x+3+4x+6+4x+6+8x+12

477 = 18x + 27

18x = 477-27

18x = 450

x = 450/18

x = 25

the amount deposited in the first week = 2x+3

First we have to split the spinner into two equal parts. One half belongs to the blue and red sections, and the other half belongs to the green and purple sections.

Formulating an equation for the first part, we have:

P(b) + P(r) = 0.5 ( P(b): probability of landing on blue section, P (r): probability of landing on red section)

P(r) + 1/2*P(r) = 0.5 ( Since it is half as likely to land on blue as to land on red)

3/2*P(r) = 0.5 (Adding like terms)

P(r)= 0.5 / (3/2) (Dividing on both sides by 3/2)

P(r)= 1/3 (Dividing)

P(b)=1/2*P(r) (Finding the probability of landing on blue section)

P(b)= 1/6

Formulating an equation for the second part, we have:

P(g) + P(p) = 0.5 ( P(g): probability of landing on green section, P (r): probability of landing on purple

section)

P(g) + 3*P(g) = 0.5 ( Since it is three times as likely to land on purple as green)

4*P(g) = 0.5 ( Adding like terms)

P(g) = 0.5/4 (Dividing by 4 on both sides of the equation)

P(g) = 1/8 (Dividing)

The truck can haul 1102 pounds.

According to the question,

We have the following information:

A Ford F-150 truck is considered a half-ton truck because that is how much it can haul.

(More to know: ton, pounds and kilograms are the most commonly used units for measuring weight.)

Now, we already have the knowledge that 1 ton is equal to 1000 kilograms.

So, half ton will make 500 kg.

Now, in order to convert this into pounds, we will multiply 500 kg by 2.205 because we know that 1 kg makes 2.205 pounds.

1 kg = 2.205 pounds

500 kg = (500*2.205) pounds

500 kg = 1102.5 pounds

Hence, the truck can haul 1102.5 pounds.

Hello!

Knowing that Alyssa wants to rent a car where the company charges $37.50 per day to rent a car and $0.05 for each mile driven we have to find out how many days she is planning on renting a car for.

Step-by-step explanation:

Using the information we have we can see that it will be an additional $5 based on how many miles she is planning on driving.

If the base cost to rent a car is $37.50 you will have to add an additional $5  for the number of miles she plans to drive making the total $42.50.

Since she has at most $200 to spend on a car rental she can rent a car for a total of 5 days at a total cost of $192.50

[tex]37.50[/tex] × [tex]4=150[/tex] + [tex]42.50[/tex] = [tex]192.50[/tex]

Hope this helps!

The inequality will be 37.5x + (0.05 ×100) ≤ 200, and Alyssa can afford 5.2 days to rent while staying within her budget

Given that the rental car company charges $37.50 per day to rent a car and $0.05 for every mile driven

She plans to drive 100 miles and has at most $200 to spend.

Let x is the number of days, Alyssa can afford to rent while staying within her budget

The inequality can be written as;

37.5x + (0.05 ×100) ≤ 200

Now solve for x:

37.5x + (0.05 ×100) ≤ 200

37.5x + 5 ≤ 200

37.5x  ≤ 200 - 5

37.5x  ≤ 195

x  ≤ 195/37.5
