To find the mean, you need to know how many numbers there are. You also need to know the sum of all the numbers.
There are 9 numbers.
The sum of the numbers is 1072.
The mean is the sum divided by the count.
The mean is 1072/9.
The mean is approximately 119.111

The graph of f(t) models the height, in feet, that a bee is flying above the ground with respect to
3241004551 [841]

Answer:

2 to 6 is constant. 14 to 15 is constant. The height characterized by the line remains straight.

Step-by-step explanation:

Looking at the graph, we can identify the x axis which is time, and the y axis which is the height. Now, as the height increases or decreases, so does the line as it goes higher or lower. Now, when the question asks what constant means, it is asking where during the graph is the height the same. We can see that it is the same when the height does not change over time, which is from 2 to 6. The height remains the same, therefore there is no change and the height is constant.

Ne4ueva [31]

Answer:

Regular hourly rate for Brandon is $30

Step-by-step explanation:

Let the payment for regular hours be $x

given that

Brandon is paid 150% of his regular hourly rate for overtime hours

payment for overtime hours = 150% of payment for regular hours

payment for overtime hours = 150/100 * x = 3x/2

Given that He is paid \$45.00 an hour for overtime hours

thus,

3x/2 = 45

=> x = 45*2/3 = 30

Thus,  regular hourly rate for Brandon is $30

Given the recursive formula shown, what are the first 4 terms of the sequence? image Question 19 options: A) 5, 20, 80, 320 B) 5
kvv77 [185]

Answer:

B) 5, 20, 80, 320

Step-by-step explanation:

Complete question

Given the recursive formula shown, what are the first 4 terms of the sequence?

f(1) = 5 if n=1

f(n) = 4f(n-1) if n> 1

A) 5. 25, 100, 400

B) 5, 20, 80, 320

C) 5, 25, 125, 625

D) 5. 14, 60, 236

Get f(2)

f(2) = 4f(2-1)

f(2) = 4f(1)

f(2) = 4(5)

f(2) = 20

Get f(3)

f(3) = 4f(3-1)

f(3) = 4f(2)

f(3) = 4(20)

f(3) = 80

Get f(4)

f(4) = 4f(4-1)

f(4) = 4f(3)

f(4) = 4(80)

f(4) = 320

Hence the first 4 terms of the sequence are 5, 20, 80 and 320
