The mean of the data is 11

now we find the difference between the mean and each number
1, 2, 3, 0.5, 0.25, 1.25, 1. 

now we square the numbers 
1, 4, 9, 0.25, 0.0625, 1.

now we find the mean of the new numbers
which is 2.1875

2.1875 is your standard deviation.

Does the point (-2, 1) satisfy the inequality 6x + y &gt; -11?<br> YES OR NO
natali 33 [55]

No, the given point does not satisfy the inequality

<em><u>Solution:</u></em>

Given inequality is 6x + y > -11

We have to find whether the point (-2, 1) satisfies the inequality

When we subsitute the given point into given inequality, values in both sides of inequality must satisfy the condition

Let us substitute the given point (x, y) = (-2, 1) in given inequality

6(-2) + 1 > -11

-12 + 1 > -11

-11 > -11 which is not true, Since -11 is equal to -11

So the given point does not satisfy the inequality

puteri [66]

Answer:

220

Step-by-step explanation:

Given that the freshman class has 160 students.

Each freshman must write three reports from a list of 12 novels that the teacher has assigned them to read

Here order does not matter.  Hence combinations can be used.

No of available options  = 12

No to be selected =3

Possible number of ways = ways of selecting 3 from 12 where order does not matter

= 12C3\\=\frac{12(11)(10)}{6} \\=220

Option B is right answer.

The equation y = 8x + 12, where x is the number of hours and y is the total cost, represents what the surf instructor charges fo
coldgirl [10]

Use the rise/run strategy to draw the line. Start at the y-intercept (0, 12), and count 8 up and 1 to the right to the point (1, 20). Then, draw a line through the points. Test the point (3,36) in the equation y = 8x + 12 to verify that the line is correct.
