Vlad [161]

Answer:

Your answer is 46 minutes.

Step-by-step explanation: By doing the median of the numbers you order the pairs from least to greatest. 38, 45, 47, 52. You find the middle number if its an even number of pairs you pick the two middle most numbers and add them together.

45 + 47= 92

Then you divide the sum by the number of pairs. Which we have 2 pairs.

92/2 = 46 hence your answer will be 46 minutes.

group of 30 students from your school is part of the audience for a TV game show the total number of people in the audience is 1

Soloha48 [4]

<h2>Answer:</h2><h2>The theoretical probability of four students from your school being selected as contestants out of 8 possible contestants spots = $\frac{14}{165}$ </h2>

Step-by-step explanation:

The number of students participated = 30

Total audience = 150

By probability , to find the solution = $\frac{n(E)}{n(S)}$

where n(E) is the number of favorable outcomes,

n(S) is the number of total outcomes.

n(S) is the number of ways any 8 students can by picked from the audience= $\frac{8}{140}$

n(E) is the probability of picking four students from our school and five students from another school.

n(E) = $(\frac{4}{30}) (\frac{4}{110})$ = $\frac{16}{3300}$

$\frac{n(E)}{n(S)}$ = $\frac{\frac{16}{3300}}{\frac{8}{140}}$ = $\frac{14}{165}$
