Jonah is purchasing a car that is on sale for 15% off. He knows the function that represents the sale price of his car is c(p) =

0.85p, where p is the original price of the car. He also knows he has to pay 9% sale's tax on the car. The price of the car with tax is f(c) = 1.09c, where c is the sale price of the car. Determine the composite function that can be used to calculate the final price of Jonah's car by solving for f[c(p)].
answers
A.f [c(p)] = 0.9265cp
B. f[c(p)] = 0.9265p
C. f [c(p)} = 1.94cp
D. f [c(p)] = 1.94p

The answer is b, f[c(p)]=0.9265p.

f[c(p)]=f(0.85p)=1.09(0.85p)=0.9265p

In a poll, 74% of the people polled answered yes to the question "Are you in favor of the death penalty for a person convicted o
Maksim231197 [3]

Answer:

324

Step-by-step explanation:

given that in a poll, 74% of the people polled answered yes to the question "Are you in favor of the death penalty for a person convicted of murder?"

i.e. Sample proportion p=0.74\\q =1-p =0.26\\

Margin of error = 4% = 0.04

Confidence level =90%

Z critical value for 90% = 1.645

Margin of error = 1.645 * std error

Hence std error = \frac{0.04}{1.645} \\=0.0243

Std error is also equal to

\sqrt{\frac{pq}{n} } =\sqrt{\frac{0.74(0.26)}{n} } =0.0243\\\sqrt{n} =18..05\\n = 325.83~324

Sample size should be 324.

The formula is sample size = (Z critical value)^2 (pq)/(Margin of error )^2

Gnom [1K]

Answer:

The answer to your question is:  111°

Step-by-step explanation:

The sum of the interior angles of a polygon is (n - 2) 180°

This polygon has 7 sides

Then n = 7

Process

  120 + 158 + 126 + 125 + 121 + 139 + x = (7 - 2)180

  120 + 158 + 126 + 125 + 121 + 139 + x = 5(180)

  789 + x = 900

  x = 900 -789

  x = 111°

Karinna's aquarium can hold 80 liters, which is equal to 80,000 cm'. The base measures 100 cm by 40
tresset_1 [31]

Answer:height=20cm

Step-by-step explanation:

Length=100cm

Breadth=40cm

Volume=80 liters which is equal to 80000cm^3

volume=length x breadth x height

80000=100 x 40 x height

80000=4000 x height

Divide both sides by 4000

80000/4000=(4000xheight)/4000

20=height

Height=20cm
