Vlad1618 [11]

Our model is

$\hat{y} = 2.17 x + -114.05$

When x=82 degrees F,

$\hat{y} = 2.17 (82) + -114.05 = 63.89$

We round up to

Answer: 64 bags

Not sure why it says y^=34 in the question; I'm ignoring that.

The residual is the difference between the actual y and the predicted y,

$e = y - \hat{y} = 66 - 64 = 2$

Roger has 2 1/2 cups of butter. A recipe for a loaf of bread requires 3/4 cup of butter. How many loaves can roger bake?

Alchen [17]

In order to calculate the number of loaves Roger can bake, we should calcculate how many times 3/4 (required butter for one loaf of bread) is included in 2 1/2 (amount of butter Roger has).

2 1/2=4/2+1/2=5/2

(5/2)/(3/4)=5*4/2*3=20/6=3,33

Roger can bake 3 loaves of bread.

5x+6y=18and 18x-15y=36 parallel or perpendicular

Katen [24]

Answer:

They are neither parallel nor perpendicular, since slope are different and not related by any equation

Step-by-step explanation:

First arrange them according to general equation:

$y = mx + c$

for the first equation :

$5x + 6y = 18 \\ 6y = - 5x + 18 \\ { \boxed{y = - \frac{5}{6} x + 3}}$

for the second equation :

$18x - 15y = 36 \\ 15y = 18x - 36 \\ y = \frac{18}{15} x - \frac{12}{5}$

72.3 + (-39.1)

joja [24]

Answer:

72.3 - 39.1 = 4tens - 7ones + 2tenth

Step-by-step explanation:

Give the expression 72.3 + (-39.1)

opening the parenthesis:

= 72.3 + (-39.1)

= 72.3 - 39.1

Breaking the decimal values into place values

72.3 = 7tens + 2units + 3tenth

72.3 = 7(10)+2(1)+3(1/10)

72.3 =70+2+0.3

Similarly for 39.1

39.1 = 3tens + 9units + 1tenth

39.1 = 3(10)+9(1)+1(1/10)

39.1 =30+9+0.1

72.3 - 39.1 = 70+2+0.3 - (30+9+0.1)

72.3 - 39.1 = 70+2+0.3 - 30-9-0.1

72.3 - 39.1 = 70-30+2-9+0.3-0.1

72.3 - 39.1 = 40 - 7 +0.2

72.3 - 39.1 = 4tens - 7ones + 2tenth
