O y = 2.29x -1.04
O y = 0.28x -0.77
O y = 77x + 28

Answers

Answer 1

Answer:

y = 0.28X - 0.77

Step-by-step explanation:

Given the data :

X:

Equation of regression line is in the form:

y = mx + c

Where y = predicted variable ;

c = intercept ; m = slope or gradient ; x = predictor variable

Using The correlation Coefficient calculator :

The regression equation obtained is :

ŷ = 0.2754X - 0.77028

Rounding values in our regression output to 2 decimal places :

y = 0.28X - 0.77

Hence best model to make prediction :

y = 0.28X - 0.77

Marcella purchased a car using a simple interest loan. The loan had an interest rate of 5.5% and was for 3 years. Marcella paid $231 in interest. The principal amount of the loan was for $_____ .

Answers

Answer:

Principal = $12600

Step-by-step explanation:

Simple Interest Formula

I = PRT

The formula for Principal Amount is:

I/RT = P

R = 5.5% = 0.055

T = 3

I = $231

P = 231 / 0.055 × 3

P =231/ 0.0183333333

P = $12600.000023

Approximately = $12600

Assume that y varies directly with x. If y=9 when x=−3, find x when y=6. Enter in any fractions using a / (e.g. "1/2" is the same as 1^/2).

Answers

Answer: 2

Step-by-step explanation:

This is a direct proportion. Since y varies as x. This will be:

y = kx

where,

y = 9

x= 3

9 = 3k

k = 9/3

k = 3

Find x when y=6

y = kx

6 = 3x

x = 6/3

x = 2

Ben is making salsa.He needs 1/3 cups of chilies for each bach of salsa.Ben has 5/6 cup green chilies.How many baches of salsa can Ben make with 5/6 cup of green chilies

Answers

Answer:

The number of batches Ben can make with 5/6 cup of green chilies is [tex]2\frac{1}{2}[/tex] batches of salsa.

Step-by-step explanation:

From the question,

Ben needs 1/3 cups of chilies for a batch of salsa.

To determine how many batches of salsa he can make with 5/6 cup of green chilies,

Let the number of batches Ben can make with 5/6 cup of green chilies be x.

Now,

If 1/3 cups of green chilies is needed for 1 batch,

Then, 5/6 cups of green chilies will make x batches

1/3 × x = 5/6 × 1

x = 5/6 ÷ 1/3

x = [tex]\frac{5}{6} \div \frac{1}{3}[/tex]

x = [tex]\frac{5}{6} \times \frac{3}{1}[/tex]

x = [tex]\frac{15}{6}[/tex]

x = [tex]\frac{5}{2}[/tex]

x = [tex]2\frac{1}{2}[/tex]

Hence, the number of batches Ben can make with 5/6 cup of green chilies is [tex]2\frac{1}{2}[/tex] batches of salsa.

A 40 kg-skier is standing at the top of a 12-meter high slope. What is her potential energy? PE = m x g x h (g = 10m/s2) A. 6000J B. 48J C. 4800J D. 400J

Answers

Answer:

The correct option is;

C. 4800 J

Step-by-step explanation:

The given parameters are;

The mass of the skier = 40 kg

The height of the slope = 12 meter

The acceleration due to gravity, g = 10 m/s²

The potential energy, PE, is given by the formula PE = Mass, m × Acceleration due to gravity, g × Height, h

Substituting the values, gives

The potential energy, PE = 40 kg × 10 m/s² × 12 m = 4800 kg·m²/s² = 4800 J

The potential energy, PE = 4800 J

A rectangle has a width of 9 units and a length of 40 units. What is the length of a diagonal? 31 units 39 units 41 units 49 units

Answers

Answer: 41 units

Step-by-step explanation: took the quiz

The length of the diagonal is 41 units.

To find the length of a diagonal.

What is rectangle?

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees.

Let a right triangle with legs length 9 units and 40 units and hypotenuse is the diagonal length c.

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

[tex]9^{2} +40^{2} =c^{2}[/tex]

[tex]81+1600=c^2\\1681=c^2[/tex]

sqrt both sides

41=c

So, the length of the diagonal is 41 units.

JJ decides to leave a tip that is 15% of the original price for his meal. How much should he leave as tip for the $5.50 cheeseburger and $2.50 milkshake? Express your answer to the hundredths place?

Answers

Answer: $9.20

Step-by-step explanation: To get the answer, you add both the cost and multiply it by .15. Then you add the product to the number you got adding the cost of the food.

Answer:

$1.20

Step-by-step explanation:

He has to leave 100% of the cost which is $5.50 + 2.50 or $8.00.

He wants to leave 115% of the $8 he has to leave.

So you set it up like

x/8 = 115/100

Then you solve for x

8(115) = 920

920/100 =9.2

So he will leave $9.20.

It then asks for just how much the tip is that he will leave so

9.2 - 8 = 1.2

So the tip is $1.20.
