Answer:

Mean is 35. Median is 28.

Step-by-step explanation:

To find the mean, you have to add all the numbers and divide it by the amount of numbers there are. So, 55 + 25 + 28 + 42 + 25 = 175. Because there is 5 numbers, do 175/5 and that is 35. To find the median, organize the numbers from least to greatest and whatever number is in the middle, is the answer. So, it is 25, 25, 28, 42, and 55. 28 is in the middle.

Answer:

median: 28

mean: 55 + 25 + 28 + 42 + 25 = 175 175 / 5= 35

Step-by-step explanation:

median is the number that is in the middle of all of the other numbers

mean is when you add all of the numbers together and then divide the total depending how many numbers you added together.

Answer:

B. 68 inches

Step-by-step explanation:

H-------J-------K

you know that HJ is 56, and JK is 2/9 × HJ.

2/9 × 56 = 12.4

you now know HJ and JK, so HK is the sum of those.

12.4 + 56 = 68.4

so HK ≅ 68 when you round the answer

Select either relation (if the set is a relation but not a function), function (if the set is both a relation and a function), o

galina1969 [7]

Answer: The correct options are

(A) relation

(B) function.

Step-by-step explanation: We are given to check whether the following set is a relation or a relation and a function or neither :

A = {(1, 2) (2, 2) (3, 2) (4, 2)} .

Let us consider the following two sets :

U = {1, 2, 3, 4} and V = {2}.

Then, we see that the Cartesian Product of U and V is given by

U × V = {(1, 2) (2, 2) (3, 2) (4, 2)}.

Since a relation is a subset of Cartesian product, so the given set A is a relation.

Also, we know that a relation is a function if every first element is associated with one second element.

Since the relation A satisfies this condition, so the relation A is a function.

Thus, the given set A is both a relation and a function.

Option (A) and (B) are correct.

To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get th

olganol [36]

Answer:

$y = 2$

Step-by-step explanation:

Given

$5 + y = 7$

Required

Solve

From the analysis attached to the question, we can solve this equation by subtracting 5 from both sides:

$5 + y = 7$

$-5 + 5 + y = 7 - 5$

$0 + y = 2$

$y = 2$

Consider the function y = 8x. How do the y-values of this function grow? by adding 8 by multiplying the previous y-value by 8 by

Tpy6a [65]

Answer:

The correct answer is by adding 8, then 16, then 32 to the first term

Step-by-step explanation:

Here, we want to know how the value of the function grows.

The function is;

y = 8x

let’s say at the first point where x = 1

Value of function will be y = 8 * 1 = 8

At second point 2;

y = 8 * 2 = 16

At the 3rd point, let’s say x = 3

y = 8 * 3 = 24

Difference between each successive term is 16-8 = 8

We can see that the third term

is the first term + 16, so the fourth will be first term + 32

So this means by adding, then 16, then 32( multiples of 8)

For the expression 6 + y − 3, determine the coefficient for the variable term.

Aleksandr-060686 [28]

6 + y - 3

We cans simplify that to:

y + 3

The coefficient is the number in front of the variable. y is nothing by 1y. So the coefficient is 1.

The variable is y.
The constant is the number without the variable, which is 3.

The answer you are looking for is 1, which is the coefficient.
