Find (f•f) (0)<br> F(x)=3x-2
NNADVOKAT [17]

Answer:  (f·f)(0) = 4

              (fof)(0) = -8

<u>Step-by-step explanation:</u>

f(x) = 3x - 2

(f·f)(x) = (3x - 2)(3x - 2)

         = 9x² - 12x + 4

(f·f)(0) = 9(0)² - 12(0) + 4

          = 4

(fof) = 3(3x - 2) - 2

       = 9x - 8

(fof)(0) = 9(0) - 8

           = -8

<em>I wasn't sure if you wanted multiplication or composition so I solved both</em>

The gross profit margin is calculated using the following rule:
gross profit margin = total profit / total sales

Now, we need to get the values of total profit and total sale:
total profit = <span>9*8-(40+8)=24$
total sales = 9*8 = 72$

Now, we will substitute in the above equation:
gross profit margin = 24/72 = 1/3 = 0.3333334
% = 0.33333334*100 = 33.3334%</span>

A sample of 64 observations has been selected to test whether the population mean is smaller than 15. The sample showed an avera
KengaRu [80]

Answer:

Test statistic = - 0.851063

- 2.520463

Step-by-step explanation:

H0 : μ ≥ 15

H1 : μ < 15

Sample mean, xbar = 14.5

Sample standard deviation, s = 4.7

Sample size = 64

Teat statistic :

(xbar - μ) ÷ (s/√(n))

(14.5 - 15) ÷ (4.7/√(64))

= - 0.851063

The critical value at α = 0.05

Using the T - distribution :

Degree of freedom, df = 64 - 1 = 63

Tcritical(0.05, 63) = 1.6694

Test statistic - critical value

-0.851063 - 1.6694

= - 2.520463
