Answer:

commutative property of multiplication

Step-by-step explanation:

The commutative property of multiplication is correct. The commutative property of multiplication is basically arranging the numbers in any way and it won't change the product.

The associative property of multiplication is arranging the numbers in parenthesis and it won't change the product either.

Answer:

$y+2=(x+2)$

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,-2) and (2,2)

substitute the values

$m=\frac{2+2}{2+2}=1$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1\\(x1,y1)=(-2,-2)$

substitute

$y-(-2)=(1)(x-(-2))$

$y+2=(x+2)$

17. Lyndsey is at basketball practice preparing to shoot free throws. The probability of Lyndsay

hram777 [196]

Answer:

Probabilty that Lindsay makes her first free throw on the third shot $=0.027$

Step-by-step explanation:

Given:

Probability of Lindsay making a free throw $=82\% =\frac{82}{100}=0.82$

To find probability of Lindsay making her first free throw in the third shot.

If Lindsay makes her first free throw on the third shot then its means the first two shots must have been unsuccessful ones.

Probability of Lindsay not making a free throw $1-0.82=0.18$

First shot ⇒ $P(unsuccessful)=0.18$

Second shot ⇒ $P(unsuccessful)=0.18$

Third shot ⇒ $P(successful)=0.82$

∴ Probabilty that Lindsay makes her first free throw on the third shot $=0.18\times0.18\times0.82=0.027$
