Answer:

B. Generate 5 random integers from 1 to 10 and see how many times the numbers 1 to 8 are generated.

Step-by-step explanation:

William wants to simulate 5 shots with an 80% chance each shot. Let's see what is each option simulate

A.

This option is wrong. Since you generate 8 different possibilities(1-8), the chance for each is 1/8= 12.5%. The chance for either 3 and 5 is 25% and it's far from 80%

B.

This option is true. You generate 5 numbers which represent the 5 shots. Since you generate 10 different possibilities(1-10), the chance for each is 1/10= 10%. The chance for 1 to 8 is 80% .

C.

There is no information about the chance for the dart score, so this option won't simulate the situation accurately.

D.

This option is wrong. You generate 3 numbers which represent the 3 shots instead of 5.

PLEASE HELP! Let f(x)= 6x+1 find f(a) + f(2)
SpyIntel [72]

Answer:

6(a)+14

Step-by-step explanation:

First you need to find f(a) and f(2) separately, then add them together after

f(a) = 6(a)+1

f(2) = 6(2)+1 = 12+1 = 13

so f(a)+f(2) = 6(a)+1+13 = 6(a)+14

Select Parameter or Statistic to classify each statement.
Annette [7]

Answer:

1) Statistic

2) Parameter

3) Statistic

4) Parameter.

Step-by-step explanation:

Parameter: is a number that describes the whole population.

Statistic: is a number that describes a sample.

The difference is:

50% of the cats are nice (parameter, because talks about all the cats)

out of 100 cats surveyed, 39 are nice (statistic, because talks about a sample of 100 cats)

Then:

1) 85% of those surveyed were in favor of bike lanes.

This only refers to the surveyed people, so this only refers to a sample (and not the population that this sample represents) then this is a statistic statement.

2) Each member of the soccer team has an average of 2 jerseys.

In this case, we are talking about the whole population (the soccer team) then this is a parameter

3) Of the 100 swim teams surveyed across America, 23 practice 10 hours a week.

Here the information is about the sample (only 100 swim teams). So here the correct option is statistic.

4) The golf team's average score is 79

Here the information is about the average score for the entire golf team, so this information is about all the population in the golf team, then in this case the correct option is parameter.
