y+4=2y-3, find y and show your work.

Answers

Answer:

y = 7

Step-by-step explanation:

we can substitute y for 7 in the equation to confirm that y = 7

7 + 4 = 2(7) - 3

7 + 4 = 14 - 3

11 = 14 - 3

11 = 11

George wants to rent a car for a road trip with his friends. He checked the rentals with two companies. Company A charges a non-refundable fee of $50 and then also $150 for each day. Company B charges using the function 50(2+1). Compare the two functions. Which function has a great rate of change?

Answers

Answer:

Company A has a greater daily rate

Step-by-step explanation:

Given

Company A

[tex]Base\ Charges=\$50[/tex]

[tex]Daily\ Rate = \$150[/tex]

Company B

[tex]f(x) = 50(2x +1)[/tex]

Required

Determine the company with greater rate

Simplify the expression of company B

[tex]f(x) = 50(2x +1)[/tex]

[tex]f(x) = 50 * 2x + 50 * 1[/tex]

[tex]f(x) = 100x + 50[/tex]

In a linear function:

[tex]f(x) = mx + b[/tex]

m represents the rates.

This implies that the rate of company B is:

[tex]Rate =100[/tex]

and the rate of company A is

[tex]Daily\ Rate = \$150[/tex]

By comparison:

Company A has a greater daily rate

What is the value of x? X-1 x-1 x - 1 28​

Answers

Answer:

X-1 X-1 X-1 28

Step-by-step explanation:

Hannah has a chicken coop with 6 hens. Let X represent the total number of eggs the hens lay on a randomly chosen day. The distribution for X is given in the table.

A 2-column table with 7 rows. Column 1 is labeled number of eggs with entries 0, 1, 2, 3, 4, 5, 6. Column 2 is labeled probability with entries 0.02, 0.03, 0.07, 0.12, 0.30, 0.28, 0.18.

Which is the correct interpretation of the standard deviation?

The number of eggs laid on a randomly selected day would typically vary from the expected number of eggs by 1.96 eggs.
The mean number of eggs laid on a randomly selected day would typically vary by 1.96 from the expected number of eggs.
The number of eggs laid on a randomly selected day would typically vary from the expected number of eggs by 1.4 eggs.
The mean number of eggs laid on a randomly selected day would typically vary by 1.4 from the expected number of eggs.

Answers

Answer:

C

The number of eggs laid on a randomly selected day would typically vary from the expected number of eggs by 1.4 eggs.

The correct interpretation of the standard deviation of the discrete distribution is:

The number of eggs laid on a randomly selected day would typically vary from the expected number of eggs by 1.4 eggs.

What is the standard deviation of a discrete distribution?To find the standard deviation, first we have to find the mean.The mean is given by the sum of each outcome multiplied by it's respective probability.The standard deviation is given by the square root of the sum of the difference squared of each outcome and the mean, multiplied by it's respective probability.It represents by how much the distribution varies from the expected value.

In this problem, the distribution is:

[tex]P(X = 0) = 0.02[/tex]

[tex]P(X = 1) = 0.03[/tex]

[tex]P(X = 2) = 0.07[/tex]

[tex]P(X = 3) = 0.12[/tex]

[tex]P(X = 4) = 0.30[/tex]

[tex]P(X = 5) = 0.28[/tex]

[tex]P(X = 6) = 0.18[/tex]

Hence, the mean is:

[tex]E(X) = 0.02(0) + 0.03(1) + 0.07(2) + 0.12(3) + 0.3(4) + 0.28(5) + 0.18(6) = 4.21[/tex]

Then, the standard deviation is:

[tex]\sqrt{V(X)} = \sqrt{0.02(0-4.21)^2 + 0.03(1-4.21)^2 + 0.07(2-4.21)^2 + 0.12(3-4.21)^2 + 0.3(4-4.21)^2 + 0.28(5-4.21)^2 + 0.18(6-4.21)^2} = 1.40[/tex]

Hence, the correct option is:

The number of eggs laid on a randomly selected day would typically vary from the expected number of eggs by 1.4 eggs.

As the measure is the number of eggs, not the mean number of eggs.

6. 188 students went on a field trip. Five buses were filled and 18
students traveled in cars. How many students were in each bus?

Answers

Answer:

34

Step-by-step explanation:

188 - 18 = 170 divided by 5 equals 34

Answer:

34 students per bus

Step-by-step explanation:

188 - 18 = 170, The number 170 is the total amount of students who were on buses

170 ÷ 5 = 34 This is the total number of students divide by the number of buses which gave the number of how many students were in each bus

Describe and correct the error in using properties of parallelograms.

Answers

Answer/Step-by-step explanation:

Opposite angles of a parallelogram are equal to each other.

Therefore, <S = <U, and <T = <V

Consecutive angles of a parallelogram are supplementary.

Therefore,

m<S + m<V = 180°

50° + m<V = 180°

m<V = 180° - 50° (subtraction property of equality)

m<V = 130°
