vredina [299]

Answer:

FG = 20 in

Step-by-step explanation:

∵ ABCD ≈ EFGH

∴ AD/EH = BC/FG

∵ AD = 45 in

∵ EH = 60 in

∴ BC = 15 in

∴ 45/60 = 15/FG

∴ FG = (60 × 15) ÷ 45 = 20 in

one town, 64% of adults have health insurance. What is the probability that 10 adults selected at random from the town all have

Katena32 [7]

Answer:

The probability that 10 adults selected at random from the town all have health insurance is 0.01153.

Step-by-step explanation:

Consider the provided information.

One town, 64% of adults have health insurance.

Let p = 64% = 0.64

Therefore, q=1-0.64=0.36

We need to find the probability that 10 adults selected at random from the town all have health insurance

Use the formula: $P(x)=^nC_r(p)^r(q)^{n-r}$

Here, the value of r is 10.

Substitute the respective values in the above formula.

$P(x)=^{10}C_{10}(0.64)^{10}(0.36)^{10-10}$

$P(x)=(0.64)^{10}(0.36)^{0}\\P(x)=(0.64)^{10}\\P(x)\approx0.01153$

Hence, the probability that 10 adults selected at random from the town all have health insurance is 0.01153.

Well the square root of 49 is 7 so anything with an absolute value over 7 would work and if it is greater than or equal to, than 7 and -7 also work :)
