Answer:

2.5

Step-by-step explanation:

From the above, we see clearly that as x increase, y also increase. This means that y is directly proportional to x. With this understanding, we can calculate the constant(K) as illustrated below:

y & x

y = Kx

K = y / x

When x = 2, y = 5

K = 5/2 = 2.5

$To\ pick = 4$

Required

Determine the number of rankings

The term "ranking" as used in this question implies permutation and the required is calculated using:

$^nP_r = \frac{n!}{(n-r)!}$

Where

$n = 7$

$r = 4$

So:

$^nP_r = \frac{n!}{(n-r)!}$

$^7P_4 = \frac{7!}{(7-4)!}$

$^7P_4 = \frac{7!}{3!}$

$^7P_4 = \frac{7 * 6 * 5 * 4 * 3!}{3!}$

$^7P_4 = 7 * 6 * 5 * 4$

$^7P_4 = 840$

Hence, number of ranking is 840

Answer:

mean is equal to 5.12

Step-by-step explanation:

We are given that 32% of college students work fulltime. We have to find the mean for the number of student s who are working full time in a sample of 16

success rate, p = 32% = 0.32

Sample size is denoted as n = 16

The forumla of mean is given as

mean = sample size × success rate

mean = n × p

= 16 × 0.32

= 5.12
