Add the numbers and divide by 5 to get a mean of 6.4

8 - 6.4 = 1.6

4 - 6.4 = -2.4

7 - 6.4 = 0.6

8 - 6.4 = 1.6

5 - 6.4 = -1.4

Add the absolute value of each: 1.6 + 2.4 + 0.6 + 1.6 + 1.4 = 7.6

Divide by 5 = 1.52

What is the equation of the line that passes through the points (1, −10) and (−4, −7)?
nignag [31]

Hi there! :)

First, let's find the slope using this formula:

m=\frac{y2-y1}{x2-x1}

m=\frac{-7-(-10)}{-4-1} \\\frac{-7+10}{-5} \frac{3}{-5} =-\frac{3}{5}

Now, use the Point-Slope formula:

y-y1=m(x-x1)

y-(-10)=-3/5(x-1)

y+10=-3/5x+3/5

y=-3/5x+3/5-10

y=-3/5x-9.4

Hope this helps..

sweet [91]

Answer:

Market price = Rs. 6,000

Step-by-step explanation:

Given:

Cost price = R.s 4,000

Profit after discount = 20%

Discount = 20%

Find:

Market price

Computation:

Sales price = Cost price[1+Profit after discount]

Sales price = 4,000[1+20%]

Sales price = 4,800

Market price = Sales price[100/(100 - Discount)]

Market price = 4,800[100/(100 - 20%)]

Market price = Rs. 6,000

An elementary school class ran 1 mile in an average of 11 minutes with a standard deviation of 3 minutes. Rachel, a student in t
EleoNora [17]

Answer:

Rachel

Step-by-step explanation:

We need to measure how far (towards the left) are the students from the mean in<em> “standard deviations units”</em>.  

That is to say, if t is the time the student ran the mile and s is the standard deviation of the class, we must find an x such that

mean - x*s = t

For Rachel we have

11 - x*3 = 8, so x = 1.  

Rachel is <em>1 standard deviation far (to the left) from the mean</em> of her class

For Kenji we have

9 - x*2 = 8.5, so x = 0.25

Kenji is <em>0.25 standard deviations far (to the left) from the mean</em> of his class

For Nedda we have

7 - x*4 = 8, so x = 0.25

Nedda is also 0.25 standard deviations far (to the left) from the mean of his class.

As Rachel is the farthest from the mean of her class in term of standard deviations, Rachel is the fastest runner with respect to her class.
