Answer:

Austin's hourly wage is $8.

Step-by-step explanation:

We can write this problem as a system of linear equations.

We define T: Tara's hourly wage, A: Austin's hourly wage and K: Kayte's hourly wage.

Then, if Tara earns twice as much per hour as Kayte, we have:

T=2K

If Kayte earns $3 more per hour than Austin, we have:

K=A+3

And if they earn $41 per hour as a group, we know:

T+K+A=41

We can use all equations to replace in the third one, as:

T+K+A=41\\\\(2K)+K+A=41\\\\3K+A=41\\\\3(A+3)+A=41\\\\3A+9+A=41\\\\4A=41-9=32\\\\A=32/4=8

Answer:

Austin's hourly wage is $8.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

Tara's hourly wage is x.

Kayte's hourly wage is y.

Austin's hourly wage is z.

Tara earns twice as much per hour as Kayte.

This means that x = 2y

Kayte earns $3 more per hour than Austin.

This means that y = z + 3

As a group, they earn $41 per hour.

This means that x + y + z = 41

What is Austin's hourly wage?​

This is z.

x + y + z = 41

y = z + 3 and x = 2y, so x = 2(z + 3) = 2z + 6

x + y + z = 41

2z + 6 + z + 3 + z = 41

4z + 9 = 41

4z = 32

z = \frac{32}{4}

z = 8

Austin's hourly wage is $8.

Fernando bought 8 pints of milk. How many fluid ounces of milk did Fernando buy?
nordsb [41]

Answer: 128 fluid ounces

Step-by-step explanation:

First and foremost, we need to realize that:

1 pint = 16 ounces

Therefore, since Fernando bought 8 pints of milk, to convert it to ounces, we just have to multiply 16 by 8. This will be:

= 16 ounces × 8

= 128 ounces

Answer:

f(x) = -34x + 320

Step-by-step explanation:

In the figure attached, the graph of the data and the options are shown.

We can see from the graph that the best fit line for the data would have a negative slope (as x values increase, y values decrease) and a positive y-intercept (the y value at x = 0). The only option that satisfies these two criteria is f(x) = -34x + 320

A researcher wants to estimate the percentage of all adults that have used the Internet to seek pre-purchase information in the
lara31 [8.8K]

Answer:

The sample size is 1875.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

The margin of error is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

Sampling error of 0.03.

This means that M = 0.03

99.74% confidence level

So \alpha = 0.0026, z is the value of Z that has a pvalue of 1 - \frac{0.0026}{2} = 0.9987, so Z = 3.

25% of all adults had used the Internet for such a purpose

This means that \pi = 0.25

What is the sample size

The sample size is n. So

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.03 = 3\sqrt{\frac{0.25*0.75}{n}}

0.03\sqrt{n} = 3\sqrt{0.25*0.75}

Simplifying by 0.03 both sides

\sqrt{n} = 100\sqrt{0.25*0.75}

(\sqrt{n})^2 = (100\sqrt{0.25*0.75})^2

n = 1875

The sample size is 1875.
