Answer:

c. 18

Step-by-step explanation:

First, you would find the total sum of the 60 numbers. The average is always the sum of the numbers divided by the number of numbers.

35*18=630

15*10=150

Now we do not know how many numbers the last group has. However, we can find it out doing 60-35-15 to see how many numbers are left. There would be 10 numbers left

10*30=300

630+150+300=1080

1080/60=18

Hence, the answer is C(18)

For a segment of a radio show, a disc jockey can play 6 records. If there are 11 records to select from, in how many ways can

saul85 [17]

Answer:

The records can be select in 332,640 ways.

Step-by-step explanation:

Consider the provided information.

There are 11 records to select from and a disc jokey can play 6 records.

Here, we need to find the number of permutation of n = 11 records taken r = 6 at a time.

Use the formula: $^nP_r=\frac{n!}{(n-r)!}$

Substitute the respective values in the above formula.

$^{11}P_6=\frac{11!}{(11-6)!}$

$^{11}P_6=\frac{11!}{5!}$

$^{11}P_6=\frac{5!\times6\times7\times8\times9\times10\times11}{5!}$

$^{11}P_6=332640$

Hence, the records can be select in 332,640 ways.

Do as the apples goes up in 4s

3 7 11 the goes 3 +4 = 7, 7+4 = 11

and Sees goes up in 40's

30 70 110

and rate of change is

$\frac{change in y}{change in x}$

its 40/4 or 10/1 (that's the first one)
