At a certain concert, 73 % of the audience was under 20 years old. A random sample of n = 146 members of the audience was select
Tatiana [17]

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

From the given slopes of the lines, identify whether the two lines are parallel, perpendicular, or neither.
vivado [14]

Answer:

Neither

Step-by-step explanation:

To be parallel the lines have to have the same slope. In this case the slopes are not the same.

To be perpendicular, the lines have to have negative reciprocal slopes.

For example, if one slope is 6, then its negative reciprocal i (- 1/6). We do not have this also.

So, the lines are no parallel and no perpendicular.
