X = 5!

4x+1=2x+11
-1 -1 (Subtract 1 from both sides)
4x =2x+10
-2x -2x (Subtract 2x from both sides)
2x = 10
—— ——
2x 2x (Divide both sides by 2x)

X = 5

Based on histogram above what is the average number of hours worked by 20 salesperson in company G

kiruha [24]

Answer:

$Average = 38$

Step-by-step explanation:

Given

The attached histogram

Required

The average work hours by 20 salespeople

First, we get the total hours worked as follows:

$Hours = 3 * 30 + 5 * 34 + 9 * 40 + 2 * 45 + 1 * 50$

$Hours = 760$

Divide by number of salespeople

$Average = Hours/n$

$Average = 760/20$

$Average = 38$

Answer:

The rule is f(x) = 2^(2x).

Step-by-step explanation:

Note that 4 = 2^2, 16 = 4^2, 64 = 8^2, 256 = 16^2 and 1024 = 32^2

and the first numbers in the ordered pairs are 1 , 2 ,3, 4, 5

compare this with 2, 4 , 8, 16 , 32.

We see that the rule for this is 2^x where x is the sequence number.

So the rule for the original ordered pairs is (2^x)^2.

= 2^2x.
