Hello from MrBillDoesMath!

Answer:

x >=4

Discussion:

The inverse of q is

-1 +\-  (x-4)^(1/4)                             (the fourth root of x-4)


(Inverse found by solving  x= (y+1)^4 +4 for y)

The domain of the inverse is therefore x such that x -4 >=0 , i.e. x >=4

MrB

P.S.  I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!

For a 95% confidence interval what would the sample size need to be as it's most conservative to have a 2% margin of error
aleksley [76]

Answer:

<em>The size of the sample 'n' = 2401</em>

Step-by-step explanation:

<u><em>Step:1</em></u>

Given that the margin of error = 2 % = 0.02

The margin of error is determined by

              M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }

we know that the proportion

               \sqrt{p(1-p)} < \frac{1}{2}

<u><em>Step:2</em></u>

<em>The margin of error is determined by </em>

<em>               </em>0.02 = \frac{1.96( \frac{1}{2} ) }{\sqrt{n} }<em></em>

              \sqrt{n} =  \frac{1.96}{2 X 0.02}

              √n  = 49

Squaring on both sides, we get

                n = 49 × 49

                n = 2401

<u>Final answer:-</u>

<em>The size of the sample 'n' = 2401 </em>

If f(x)=2x and g(x)=x^2 -1, which statement is true?
choli [55]

Answer: D

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

f(x) = 2x     g(x) = x² - 1

f(g(x)) = 2(x² - 1)

         = 2x² - 2

g(f(x)) = (2x)² - 1

         = 4x² - 1

16) A company has found that its expenditure rate per day (in hundreds of dollars) on a certain type of job is given by E'(x) =
erastova [34]

Answer:

$61

Step-by-step explanation:

Given

Number of days, x = 5

Expenditure per day, E'(x) = 10x + 11

Required

Determine the expenditure per day (E'(x))

From the question, we have that

E'(x) = 10x + 11

Substitute 5 for x

E'(5) = 10 * 5 + 11

E'(5) = 50 + 11

E'(5) = 61

Hence, the expenditure for 5 days is $61
