Question:

Which of these linear equations best describes the given model? Choose 1 answer:

Choose 1 answer:

A [tex]\hat y=10x+20[/tex]

B [tex]\hat y=20x+20[/tex]

C [tex]\hat y=-20x+20[/tex]

Based on this equation, estimate the score for a student that spent 3.8 hours studying.

Answer:

[tex]\hat y = 20x +20[/tex]

Score of 96 for studying 3.8 hours

Step-by-step explanation:

Given

See attachment for graph

From the straight line of trend, we have:

[tex](x_1,y_1) = (0,20)[/tex]

[tex](x_2,y_2) = (2,60)[/tex]

The slope (m) is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{60 - 20}{2 - 0}[/tex]

[tex]m = \frac{40}{2}[/tex]

[tex]m = 20[/tex]

The equation is calculated using:

[tex]\hat y = m(x - x_1) + y_1[/tex]

This gives:

[tex]\hat y = 20(x - 0) +20[/tex]

[tex]\hat y = 20(x ) +20[/tex]

[tex]\hat y = 20x +20[/tex]

Solving (b): When study hours is 3.8

This means that [tex]x= 3.8[/tex]

So:

[tex]\hat y = 20x +20[/tex]

[tex]\hat y = 20 * 3.8 + 20[/tex]

[tex]\hat y = 96[/tex]

Probability of choosing CD

From the attachment:

[tex]CD=D-C[/tex]

[tex]CD=3 - 2[/tex]

[tex]CD = 1[/tex]

So:

[tex]P(CD) = \frac{CD}{AK}[/tex]

[tex]P(CD) = \frac{1}{10}[/tex]

Answer:

124 inches square

Step-by-step explanation:

First area of that rectangle 20×5 = l×b = 100

Second area of that triangle 6×8×1/2 = 24

Third add both rectangle+triangle=100+24=124

The value of the quotient of 50 and 5 subtracted from 20 that can be given as 10.

It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.

Firstly, we have the quotient of 50 and 5. This can be written as

[tex]\dfrac{50}{5}[/tex]

And we know that this can be written as 10.

Now we subtract it from 20. Then we have the number 20 and we subtract 10 from it. Then it can be written as

20 - 10

On subtracting, we have

20 - 10 = 10.

How the sales tax calculator works

Step 1: take the total price and divide it by one plus the tax rate.

Step 2: multiply the result from step one by the tax rate to get the dollars of tax.

Step 3: subtract the dollars of tax from step 2 from the total price.

Pre-Tax Price = TP – [(TP / (1 + r) x r]

TP = Total Price.
