Step-by-step explanation:

we know the formula:

  1. A=P(1+r/n)^nt ,where A is the amount , P is the principle , r is the rate , n is the number of times the interest compounded per unit time

68921=64000(1+0.05/2)^2t

or,68921/64000=(41/40)^2t

or, (41/40)^3=(41/40)^2t

or 2t=3

or, t=3/2 years

Kobotan [32]

÷you need to find how many parts there are ;    4 + 3 = <u>7</u>

<u />1 part = <u>£8</u>

<u />4:3, 4 parts : 3 parts.   

   4  x  £8   =  <u>£32</u>

   3  x   £8  =  <u>£24</u>

The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 33
Tpy6a [65]

Answer:

The estimate for the proportion of Americans over 33 who smoke is 0.28.

Step-by-step explanation:

Proportion of Americans over 33 who smoke.

Number who smoke divided by the size of the sample.

In this question:

Sample of 1267.

913 don't smoke, so 1267 - 913 = 354 smoke. Then

p = \frac{354}{1267} = 0.28

The estimate for the proportion of Americans over 33 who smoke is 0.28.

In a sample of 150 cars, 18 cars failed a safety inspection. The sampling method had a margin of error of 0.02
mestny [16]

Answer:  

(Lower limit, Upper limit) = (0.10, 0.14)

(Lower limit, Upper limit) = (10%, 14%)

Step-by-step explanation:  

Total number of cars = 150

Cars that failed the safety inspection = 18

The proportion is given by

p = 18/150

p = 0.12

p = 12%

The confidence interval is given by

p ± margin of error

Where margin of error is 0.02

0.12 ± 0.02

Lower limit = 0.12 - 0.02

Lower limit = 0.10

Lower limit = 10%

Upper limit = 0.12 + 0.02

Upper limit = 0.14

Upper limit = 14%

(Lower limit, Upper limit) = (0.10, 0.14)

(Lower limit, Upper limit) = (10%, 14%)
