The percentage of men is more than 72 inches tall will be 0.15866.

<h3>What is the z-score?</h3>

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x – μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

Suppose the mean height for men is 70 inches, with a standard deviation of 2 inches.

Then the percentage of men are more than 72 inches tall will be

z = (72 – 70) / 2

z = 1

The percentage of men is more than 72 inches tall will be

P(x > 72) = P(z > 1)

P(x > 72) = 1 – P(x < 72)

P(x > 72) = 1 – 0.84134

P(x > 72) = 0.15866

Thun, the percentage of men are more than 72 inches tall will be 0.15866.

More about the z-score link is given below.

7. A consultant earns $30 per hour. The consultant's daily work expenses total $8. The consultant can
QveST [7]

Answer:

The consultant's possible daily profit is $232, given that the work expenses ($8) is a daily thing and not an hourly thing.

Step-by-step explanation:

To construct a graph, you first need to figure out the possible daily income. Given that the consultant makes $30 an hour and works 8 hours a day, they make $240 from work. However, they lose $8 of that due to work-related expenses, so in total, they make $232 a day. Now time to construct a graph.

For the x-axis, you want to put the number of days worked (1, 2, 3, 4, 5). For the y-axis, you want to put the profits ($232, $464, $696, $928 and $1160). Place dots at (1, 232), (2, 464), (3, 696), (4,928) and (5,1160), and draw a line through. It will show the daily profit as $232.

Write an equation in slope-intercept form of the line that passes through (-1, 4) and (0, 2).
arsen [322]

Answer:

y=-2x+2

Step-by-step explanation:

Hi there!

Slope-intercept form: y=mx+b where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

<u>1) Determine the slope</u>

m=\frac{y_2-y_1}{x_2-x_1} where the two given points are (x_1,y_1) and (x_2,y_2)

Plug in the given points (-1, 4) and (0, 2)

=\frac{2-4}{0-(-1)}\\=\frac{-2}{0+1}\\=\frac{-2}{1}\\= -2

Therefore, the slope of the line is -2. Plug this into y=mx+b:

y=-2x+b

<u>2) Determine the y-intercept</u>

y=-2x+b

Recall that the y-intercept is the value of y when the line crosses the y-axis, meaning that the y-intercept occurs when x is equal to 0.

One of the given points is (0,2). Notice how y=2 when x=0. Therefore, the y-intercept of the line is 2.

Plug this back into the equation:

y=-2x+2

I hope this helps!

A concession stand sells hamburgers (h) for $2 and hotdogs(d) for $1.On friday night they sold a total of 300 hamburgers and hot
Olegator [25]
The first equation has to be the sum of hotdogs and hamburgers. Since a total of 300 <span>hamburgers and hotdogs was sold, the first equation is:
          h+d=300

Now, the second equation is about the money. They say that EACH hamburger cost $2 and each hotdog cost $1. And, the total amount of money made was $420. So the second equation is:

      2h+d=420

SO, overall, the system of equations is this:

   
h+d=300
   2h+d=420
     
(option A is the answer)
