As part of a quality-control program, 4 batteries from a box of 17 is chosen at random for testing. In how many ways can this te

belka [17]

Answer:

This test batch can be chosen in 2380 ways

Step-by-step explanation:

The order in which the batteries are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In how many ways can this test batch be chosen?

4 batteries from a set of 17. So

$C_{17,4} = \frac{17!}{4!(17-4)!} = 2380$

This test batch can be chosen in 2380 ways

Tpy6a [65]

Answer:

62.8% OR 0.628

Step-by-step explanation:

11 hours playing video games

11 hours on the Internet

11 + 11 = 22

5 hours of free time each day

7 days in a week

5 x 7 = 35

22/35 hours are spent

That is 0.62857142857 or I just mathmatically rounded to 0.628

0.628 into a fraction is 62.8%

sesenic [268]

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −6?

Parallel, slope is the same, perpendicular slope is opposite and reciprocal

so

line n, with slope −6 , same slope -----> Parallel

line p, with slope 1/6 , opposite and reciprocal -----> Perpendicular

line q, with slope −1/6 , -----> Neither

line m, with slope 6, -----> Neither
