Isabella backed cookies for 3 hours. She spent the same amount of time baking each batch. It took her one eighth an hour to bake

katovenus [111]

I believe it is 24 batches:

because there are 8/8 in one hour, so you multiply that by three. which would give you 24!

Four times the greater of two consecutive integers is 18 more than three times the lesser integer. What are the integers?

maw [93]

This is how I would solve it:

1st # = x 4(x+1)=3x+18
2nd # = x+1 4x+4=3x+18
4x=3x+14
x=14

To check: 15x4=60; 60-42=18. <u>1st # = 14; 2nd # = 15.</u>

Given that x overbarequals3.6667, s Subscript xequals2.0656, y overbarequals4.2167, s Subscript yequals1.5613, and requalsne

Shtirlitz [24]

Answer:

$y = 0.7063x+2.7790$

Step-by-step explanation:

Given that

$x bar = 3.6667\\s_x= 2.0656\\y bar = 4.2167\\s_7 = 1.5613\\r = -0.9344$

We have slope of linear regression line is

$a=r*\frac{s_y}{s_x} =0.9344(\frac{1.5613}{2.0656} )\\=0.7063$

So regression line would be of the form

$y-4.2167 = 0.7063(x-2.0656)$ (since it passes through xbar, y bar)

$y = 0.7063x+2.7790$

is the equation of regression line.
