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
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.

Solve for X and Solve for Y
Answers
Answer:

Step-by-step explanation:

EXPLANATION:
Angles inside a triangle add up to 180 degrees, and the angle of a line is 180 degrees. Given we have the angle outside the triangle of 124, do 180-124 to get x, or 56. Now we add 56 and 59, subtract that from 180, and get our y value!

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.
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
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.

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
