What is the slope of a line that passes through the point (-3,0) and has a y-intercept of 12
Trava [24]

The slope of a line that passes through the point (-3,0) and has a y-intercept of 12 is 4.

<h3>How to find the slope of a line?</h3>

Using the point slope equation,

y = mx + b

where

  • m = slope
  • b = y-intercept

Therefore, using (-3, 0)

0 = -3m + 12

-12 = -3m

divide both sides by -3

m = -12 / -3

m = 4

Males have red blood cell counts with a mean of 4.719 and a standard deviation of .490, while females have red blood cell counts
iVinArrow [24]

Answer:

  • <em><u>The female  has a higher count relative to the sample of females than the male relative to the sample of males.</u></em>

Explanation:

When you want to compare the means of two samples with different statistics you may use the z-score.

The z-score measures how far a value (data point) is from the mean, in terms of the standard deviation.

The z-score is calculated as:

          z-score=(x-\mu )}/\sigma

Where:

          x=\text{value of the data}\\\\\mu =mean\\\\\sigma = \text{standard deviation}

<u>1. Male with a count of 5.58 </u>

       z-score=(5.58-4.719)/0.490=1.757

<u />

<u>2. Female with a count of 5.23</u>

     z-score=(5.23-4.349)/0.402=2.192

Therefor, the z-score of the female is greater than the z-score of the male.

The greater z-score means that, relative to her group, the female has a higher count than the male.

A square has a perimeter of 28 feet what is its area
Westkost [7]
Given:
square shape
Perimeter 28 feet
Find its area

A square has 4 equal sides, so perimeter is 4a

Perimeter = 4a
28 ft = 4 a
28 ft / 4 = a
7 = a

One side of the the square is 7 ft.

Area of a square is the measure of one side raised to the power of 2.

A = a²
A = (7 ft)²
A = 49 ft²
