Sharonda uses a blend of dark chocolate and milk chocolate to make the ice cream topping at her restaurant. She needs to buy 120

The answer with the work has been provided previously.

Answer:

(C) They have the same coefficient of variation

Step-by-step explanation:

The coefficient of variation (CV) is calculated using the formula:

Where represents standard deviation and represents the mean.

Bob's average weight is 200 pounds with a standard deviation of 16 pounds

This indicates that .

Thus, his coefficient of variation is

Mary's average weight is 125 pounds, with a standard deviation of 10 pounds.

This implies

Therefore, her coefficient of variation is

Since both have the same coefficient of variation, the accurate response is.

(C) They have the same coefficient of variation

In the first month, she made a payment of $1451

In the second month, she paid one-third of that, which amounts to:
1451/3 = 483.66

For the third month, she pays one-third of 483.66 as indicated, meaning she takes one-third of the prior month's payment.

483.66/3 = 161.22

In the fourth month, her payment was

161.22/3 = 53.74

Altogether, her total payments amounted to:

$2149.62 - B.

Answer:

The hourly rate for lectures is $7.33

Step-by-step explanation:

* Let's break down how to tackle the problem.

- For the level 3 course, examination hours are priced at double that of workshop hours.

- Workshop hours cost twice the rate of lecture hours.

- The total includes examination, workshop, and lecture hours.

- Examination lasts 3 hours, workshops 24 hours, and lectures 12 hours.

* Let’s denote the cost of lecture hours as $x per hour.

∴ The lectures cost $x per hour.

∵ Workshop charge is twice that of lectures

∴ Workshop hours cost 2(x) = 2x per hour.

∵ Examination fees are double that of workshop hours

∵ The workshop cost is 2x

∴ Examination fees are 2(2x) = 4x per hour.

- Combining costs for level 3 gives us the total of lecture, workshop, and examination hours.

∵ 12 hours for lectures

∵ 24 hours for workshops

∵ 3 hours for examinations

∵ Thus the total cost for level 3 = 12(x) + 24(2x) + 3(4x).

∴ Total cost for level 3 = 12x + 48x + 12x.

∵ Therefore, total cost = $528.

∴ 12x + 48x + 12x = 528.

∴ 72x = 528; hence we divide both sides by 72.

∴ x = 7.33.

∵ x represents the cost of lecture hours per hour.

∴ Therefore, the hourly price for lectures is $7.33.

we have the function

we understand that

In the context of the exponential function represented as

a signifies the initial value

b denotes the base

x represents the exponent

The initial value indicates the function's value when x equals zero

in this scenario

for

the initial value corresponds to the point
