Answer:

See explanation below

Step-by-step explanation:

To find the principal square root of a number, we the number with an index of 2. The base then become the principal square root.

In the same way, we find the cube root of a number by writing the  number with an index of 3 and the base becomes the cube root of the given number.

For instance:

64=8^2\implies 8=\sqrt{64}

64=4^3\implies 4=\sqrt[3]{64}

As a salesperson you get $23/ day and $3.60/each sale you make. If you want to make at least $84. in one day, how many sales wou
Anettt [7]

Answer:

c 17

Step-by-step explanation:

You make 23 a day plus 3.60 per sale

Income = 23+ 3.6 s

You want to make at least 84

84 ≤ 23+ 3.6 s

Subtract 23 from each side

84 -23 ≤ 23-23 +3.6s

61 ≤ 3.6s

Divide by 3.6 on each side

61/3.6 ≤ 3.6s/3.6

16.94444 ≤ s

You must make more than 16.94444 sales

But you cannot make part of a sale so

You must make at least 17 sales

a_sh-v [17]

Answer:

John's standard z-score is 2.383

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = $810

John's rent = $1370

Population standard deviation, σ = $235

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

Putting all the values, we have

z_{score} = \displaystyle\frac{1370 - 810}{235} = 2.383

John's standard z-score is 2.383
