The value of the given expression is 1/16
<h3>Exponential functions</h3>
Given the exponential function below as shown;
(1/2)^4
This means the product of 1/2 in 4 places. This can be expressed as;
(1/2)^4 = 1/2 * 1/2 * 1/2 *1/2
(1/2)^4 = 1/4 * 1/4
(1/2)^4 =1/16
Hence the value of the given expression is 1/16

Answer: p = 0.73
Step-by-step explanation:
Given that,
73% of the audience was under 20 years old :
so, probability (p) = 0.73
n = 146
Mean of the distribution of sample proportion = ?
According to central limit theorem,
np(1-p) ≥ 10
146 × 0.73(0.27) ≥ 10
28.77 ≥ 10
∴ Central limit theorem assumes that the sample distribution of the sample proportion is normally distributed.
Hence, the mean of the distribution of sample proportion:
μ = p = 0.73
Answer:
Step-by-step explanation:
125 miles / 150 minutes = 300 miles / x Criss multiply
Notice that the numerators both have the same units -- miles. Proportions should always be set up that way.
125 x = 150 * 300 Combine the right
125x = 45000 Divide by 125
x = 45000/125
x = 360 more minutes which is 6 hours.
