A popular art teacher at a school asks a sample of students if they would be interested in taking an art class next year. Of the

30 students he ​asks, 85​% are in one of his art classes this year. Only 15​% of the students in the school are in one of his art classes this year. Will this sample be​ biased? *
​Yes, because students who are in one of his art classes this year will be more likely to take one of his art classes next year.
​No, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.
​Yes, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.

Point m is the midpoint of ab¯¯¯¯¯ . am=3x+3, and ab=8x−6. what is the length of am¯¯¯¯¯¯ ?
LuckyWell [14K]
As given m is a midpoint of ab. So am is half of ab.

So we can write

am =  \frac{ab}{2}

As given am = 3x+3 , ab = 8x - 6.

So 3x+3 = \frac{8x - 6}{2}

3x+3 =  \frac{2(4x - 3)}{2}

3x+3 = 4x - 3

3+3 = 4x - 3x


6 = x

So x = 6.

So length of am = 3x+3 = 3*6 + 3 = 21

Write the quadratic equation that has roots -1-rt2/3 and -1+rt2/3 if its coefficient with x^2 is equal to 1
weeeeeb [17]

The equation of the quadratic function is f(x) = x²+ 2/3x - 1/9

<h3>How to determine the quadratic equation?</h3>

From the question, the given parameters are:

Roots = (-1 - √2)/3 and (-1 + √2)/3

The quadratic equation is then calculated as

f(x) = The products of (x - roots)

Substitute the known values in the above equation

So, we have the following equation

f(x) = (x - \frac{-1-\sqrt{2}}{3})(x - \frac{-1+\sqrt{2}}{3})

This gives

f(x) = (x + \frac{1+\sqrt{2}}{3})(x + \frac{1-\sqrt{2}}{3})

Evaluate the products

f(x) = (x^2 + \frac{1+\sqrt{2}}{3}x + \frac{1-\sqrt{2}}{3}x + (\frac{1-\sqrt{2}}{3})(\frac{1+\sqrt{2}}{3})

Evaluate the like terms

f(x) = x^2 + \frac{2}{3}x - \frac{1}{9}

So, we have

f(x) = x²+ 2/3x - 1/9

Find the mean absolute deviation of the set of data 3,8,10,12,15
klio [65]
3 + 8 + 10 + 12 + 15 = 48

48 / 5 = 9.6 or 10

3 - 7
8 - 2
10 - 0
12 - 2
15 - 5

7 + 2 + 0 + 2 + 5 = 16

16 / 5 = 3.2 or 3

The Mean Absolute Deviation is approximately 3

ILL GIVE BRAINLIEST 25 POINTS

Answer:

Step-by-step explanation:

You shift up and down when there is a value at the end of the function outside of the parentheses. Since it is -1, you shift down one.

You shift left and right when there is a value inside the parentheses. Since it is 2, you shift left 2. Remember that you always shift left if the number positive and you shift right when it is negative.
