Answer:

y=3

Step-by-step explanation:

-7y - 17 = -38

Add 17 both sides

-7y - 17 + 17= -38+17

7y= -21

Divide both sides by -7

\dfrac{-7y}{-7}=\dfrac{-21}{-7}

y=3

Forty percent of the homes constructed in the Quail Creek area include a security system. Three homes are selected at random: Wh
suter [353]

Answer: 0.064

Step-by-step explanation:

Binomial probability formula :-

P(X)=^nC_x \ p^x\ (1-p)^{n-x}, where P(x) is the probability of getting success in x trials, n is total number of trials and p is the probability of getting succes in each trial.

Given : The proportion of the homes constructed in the Quail Creek area include a security system :  p=0.40

Now, if three homes are selected at random, then the probability all three of the selected homes have a security system is given by :-

P(3)=^3C_3 \ (0.40)^3\ (1-0.40)^{3-3}\\\\=(0.40)^3=0.064

Hence, the probability all three of the selected homes have a security system = 0.064

Please help me with question b) and please explain!!<br>look at the attached image
natta225 [31]

Answer:

17

Step-by-step explanation:

let x be the number of boxes to be shaded to make it 80%

x = 80% of total number

= 80/100 of 25

= 80/4

= 20

So 20 need to be shaded to fill 80%

Now, 13 of the grids are already shared so the amount of more squares that need to be shaded = 20-13

= 17 squares
