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

Answers

Answer:

y = 0.28X - 0.77

Step-by-step explanation:

Given the data :

у:

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

Round 243.583 to the nearest tenth *

Answers

Answer: 243.6

Step-by-step explanation:

For us to solve the question and round off 243.583 to the nearest tenth. First, we need to look at the number beside the tenth number which is 8.

Since 8 is more than 4, we simply add 1 to the tenth number which implies that we add 1 to the number in tenth place which is 5. Adding one means the number change to 6. Therefore, rounding 243.583 to the nearest tenth will be 243.6.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say the first number is x, the second is y and the third is z.

The sum of three numbers is 17 ⇒

x + y + x = 17

The sum of twice the first number, 4 times the second number and 5 times the third number is 56 ⇒

2x + 4y + 5z = 56

The difference between 7 times the first number and the second number is 41 ⇒

7x - y = 41 ⇒ y = 7x - 41

By substituting this y into the above equation.

A newly formed equation will be

-40x - 5z = -290

30x + 5z = 220

By solving them x = 7 and z = 2 by that y = 8

Hence all three values will be 7,2 and 8.

The chef is making 10.5 batches of dinner rolls for each batch he kneaded dough for 0.7 hours and let the dough rest for 1.6 hours then he bake the dough for 0.4 hours how long does it take to make each batch of dinner rules

Answers

Answer:

2.7 hours

Step-by-step explanation:

From the question, chef is making 10.5 batches of dinner rolls , for each batch he kneaded dough for 0.7 hours and let the dough rest for 1.6 hours then he bake the dough for 0.4 hours . Which means for every batch of the roll the roll must ;

kneaded for 0.7 hours

rest for 1.6 hours

baked for 0.4 hours

Then the addition of all this hours will give us the total hours it take to make each batch of dinner rules

We can do that Mathematically as

(0.7 hrs +1.6 hrs +0.4 hrs)

= 2.7 hrs

Therefore,to make each batch of dinner rules It willtakes 2.7 hours

Find the equation of a line that passes through points A and B.

Answers

Answer:

y = 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2, 3)

m = = = 2, thus

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation.

Using B(2, 3), then

3 = 4 + c ⇒ c = 3 - 4 = - 1

y = 2x - 1 ← equation of line
