According to historical data, it is believed that 12% of American adults work more than one job. To investigate if this claim is

still accurate, a random sample of 100 American adults is selected. It is discovered that 18 of them work more than one job. A researcher would like to know if the data provide convincing evidence that the true proportion of American adults who work more than one job differs from 12%. What are the values of the test statistic and P-value for this test?
Find the z-table here.

z = 1.85, P-value = 0.0322
z = –1.85, P-value = 0.0322
z = 1.85, P-value = 0.0644
z = –1.85, P-value = 0.0644

Danielle earns a 7.75% commission on everything she sales at the electronic store where she works. She also earns a base salary
Andrew [12]

The first thing thing you must do is create an equation for this problem. Remembering that 7.75% = 0.0775

($4,100 × 0.0775 + $4,100 ) + $600

Now, all you have to do is solve it. You will first have to start with the numbers in the parenthesis using the order of operation (PEMDAS).

P = Parenthesis

E = Exponent

M = Multiplication

D = Division

A = Addition

S = Subrtaction

$4,100 × 0.0775 + $4,100 ) + $600

$4,417. 75 + $4,100 + $600

$4,417. 75 + $600 = $5,017.75

Danielle made $5,017. 17 last week.

I hope this helps! :)

Find the critical numbers of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE
zhannawk [14.2K]
H(t) = t^(3/4) - 3t^(1/4)

The critical points can be evaluated by taking the first derivative and equating to 0.

h'(t) = 3 / t^(1/4)  - 3 / 4t^(3/4)
3 / (4t^(3/4)) = 3 / t^(1/4)
4t^(3/4) = t^(1/4)

4 = 1/√t
t = 1/16, t = -1/16
