The correct answers are A and E.
The mean is affected by outliers.
It a data set is skewed to the right, the mean will be larger than the median because the median is in the middle so will fall in the lower range while the mean is an average of all of the values, so the skewness pulls the mean toward the right, toward higher values.

Write an equation of the circle with center (-7,4) and radius 11.

olga_2 [115]

Answer: (x+7)^2 + (y-4)^2 = 121 or (x+7)^2 + (y-4)^2 = 11^2

Step-by-step explanation:

Equation of the circle is:

$(x-h)^2+(y-k)^2=r^2$ , which is the center $(h,k)$ and the radius $r^2$

-Place the center (-7,4) and radius 11 onto that equation:

$(x+7)^2+(y-4)^2=121$ (if simplified radius needed)

$(x+7)^2(y-4)^2=11^2$

a beekeeper estimates that his bee population will triple each year. Currently he has 150 bees. Write a function to represent th

Soloha48 [4]

Answer:

Exponential functions!

Step-by-step explanation:

I think what you are dealing with is an exponential function!

So, to solve this, we need to first understand the main form of an exponential function:

$f(x)=a*b^{x}$

Where a is the number we start off with, and b is the constant thing(forgot what it was called).

Now, 150 is our starting number, so it is a, and b is our constant at which the initial term is multiplied, which is 3!

Also, defining variables:

Let f(x)= # of Bees

Let x= # of years

Thus, here is our equation:

$f(x)=150*3^{x}$

So, that's it!

Now, some of my answers have been recently deleted because they violated community guidelines for recommending something that shall not be named, so if you do really need help on the subject, look online! It is the largest source of information humanity has created! (also I cannot explain Exponential Functions in a single paragraph)

If these two shapes are<br> similar, find X

ELEN [110]

Answer:

Step-by-step explanation:

If the shapes are similar we can use the side length proportion to find the value of x:

7/91 = x/52 cross multiply expressions

91x = 364 divide both sides by 91

x = 4

PLEASE HELP < I NEED HELP, TRYING TO MAKE HONOR ROLL

Stels [109]

Answer: w = 4 $\frac{1}{3}$

Step-by-step explanation:

Let the unknown number be w , then

the product of w and 3 = 3w

Nine less than the product of 3 and the number = 3w - 9

completing the equation , we have

3w - 9 = 4

add 9 to both sides

3w = 13

w = 13/3

w = 4 $\frac{1}{3}$
