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

Help please!! 1. What is the value of n? 2.What is the value of n?

lana66690 [7]

Using the intersecting chord theorem:

15 x 2 = 5 x n

Simplify:

30 = 5n

Divide both sides by 5:

n = 30/5

n = 6 m

8 x n+8 = 16 x n+2

Simplify:

8n +64 = 16n +32

Subtract 8n from both sides:

64 = 8n +32

Subtract 32 from both sides:

32 = 8n

Divide both sides by 8:

n = 32 /8

n = 4

Find all the missing elements: 40° 120° 8 C = [?]º a = [ ] c = [ ]

Ede4ka [16]

Answer:

C=20° a=10.8 c= 4.3

Step-by-step explanation:

first we need to find the value of angle C by subtracting the sum of angle A and B from 180°.

to find c and a we need to use sin rule which states that sinB/b=sinA/a=sinC/c respectively

What are the factors of 36? And is it prime or composite

stepladder [879]

Answer:

Step-by-step explanation:

Notice that

$96 = 9 \times 4\\= 3^2 \times 2^2\\$

So the factors of 36 are all of the form $3^a\times 2^b[\tex] where [tex]0\leq a,b\leq 2$ .

If we list all of them we have
