A car salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of ​$16.

Option B is a commission rate on weekly​ sales, and he averages ​$6400 in sales each week. What commission rate does he need to have to earn the same amount with the two​ options?

10%

since he works 40 hours per week and gets $16 an hour, that would be 16 * 40 which is 640, so that means he needs a commission rate of 10% as 10% of 6400 is 640.

hope this is helpful!

I WILL MAKE YOU THE BRANLIEST
Anuta_ua [19.1K]

The area of a triangle is given by half the multiplication of base and height. Since you want the answer is squared centimeters, let's convert base and height in centimeters first:

b = 4.3 m = 430 cm, \qquad h = 2.6m = 260 cm

Now we can do the computation:

A = \dfrac{430cm \cdot 260cm}{2} = 55900 cm^2

A researcher wants to study the average miles run per day for marathon runners. In testing the hypotheses: H0: μ = 25 miles vs.
masya89 [10]

Answer:

The calculated value |Z|  = 1.325  < 1.881 at 0.03 level of significance

Null hypothesis is accepted

Alternative hypothesis is rejected

A researcher wants to study the average miles run per day for marathon runners is 25

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given sample size 'n' = 36

Given mean of the sample x⁻ = 22.8 miles

Given mean of the Population 'μ' = 25

Given standard deviation of the Population 'σ' = 10

<u><em>Null hypothesis:-H₀: μ = 25</em></u>

<u><em>Alternative Hypothesis:H₁:μ ≠ 25</em></u>

Level of significance  = 3 % or 97%

The critical value  Z₀.₉₇ = 1.881

<u>Step(ii):</u>-

Test statistic

           Z  = \frac{x^{-} - mean}{\frac{S.D}{\sqrt{n} } }

          Z  = \frac{22.8 - 25}{\frac{10}{\sqrt{36} } }

          Z = -1.325

       |Z| = |-1.325| = 1.325

The calculated value |Z|  = 1.325  < 1.881 at 0.03 level of significance

Null hypothesis is accepted

Alternative hypothesis is rejected

<u>conclusion:-</u>

A researcher wants to study the average miles run per day for marathon runners is 25

2 gallons of soup 15 cups of soup
kirill [66]
If it's a hearty soup that is served as the meal itself, and served with bread or crackers and salad, then you can figure about 2 cups per person. Since there are 16 cups to a gallon, that would give you 8 servings. If it's a lighter soup that is served as part of a 5 - 7 course meal, then you can figure about 1 cup person, which would be 16 servings.

Help math math math
lutik1710 [3]

Hello.

In order to convert this equation into slope intercept form, we need to divide the entire equation by 7:

\tt{8x-7y=13

\tt{\displaystyle\frac{8x}{7} -\frac{7y}{7}=\frac{13}{7}

Simplify:

\tt{\displaystyle\frac{8x}{7}-y=\frac{13}{7}

Add y to both sides:

\Large\boxed{\sf{y=\displaystyle\frac{8x}{7} -\frac{13}{7}}}

I hope it helps.

Have an outstanding day. :)
