Hello!

First, let's find the mean. We add up all of our numbers and divide by the number of numbers.

15+4+4+8+7=15+4+15+4+5=81

81/10=8.1

Therefore, our mean is 8.1.

Now we need to find the median. To do so, we first order our numbers from least to greatest.

4,4,4,4,5,7,8,15,15,15

Now we need to find the middle number. As there are 10 numbers, we find the mean of the two middle numbers, which are 5 and 7.

5+12

12/2=6

Therefore, our median is 6.

Now, we need to find the mode. This is the number that appears the most. As you can see, 4 appears the most.

Therefore, 4 is our mode.

I hope this helps!

Mean is the average. To calculate mean, add all the numbers and divide by how many numbers there are.

15 + 4 + 4 + 8 + 7 + 15 + 4 + 15 + 4 + 5 = 81

There are 10 numbers. Divide by 10

81 \div 10 = 8.1

The mean is 8.1

Median is the middle number when ordered from least to greatest. Order the numbers:

4, 4, 4, 4, 5, 7, 8, 15, 15, 15

The 2 middle numbers are 5 and 7. Add them together and divide by 2

7 + 5 = 12 \\ 12 \div 2 = 6

The median is 6

Mode is the number that appears most often.

4 \rightarrow 4\ times \\ 5 \rightarrow 1\ time \\ 7 \rightarrow 1\ time \\8 \rightarrow 1\ time \\ 15 \rightarrow 3\ times

4 appears the most. The mode is 4

that gives us 92/6 = 15.333... or 15

Median: order it:

9, 14, 14, 18, 18, 19

median is 16

2 averages

Median: 16

I wasn't in class so I need help solving the inequality 7/10n+14&lt;49
NikAS [45]

Answer:

n<50

Step-by-step explanation:

7/2*5n + 14<49

7n/2*5+14<49

(7n)+(2*5)14/2*5 <49

7n+10*14/2*5 <49

7n+140/2*5 <49

7n+140/10 <49

7n+140 < 10*49

7n+140 < 490

(7n+140)+(-140)<490+(-140)

7n+140-140<490-140

7n<350

7n/7 < 350/7

n<2*5^2*7/7

n<2*5^2

n<2*25

n<50

Which of the following is a proportional relationship?
Solnce55 [7]

The two equations represent the proportional relationship.

y=3x and y=12x are proportional relation ship equations

proportion equations can be defined as

If we change x the y will change in the same proportion.

<h3>What is the proportional relationship?</h3>

Proportional relationships are relationships between two variables where their ratios are equivalent.

Another way to think about them is that, in a proportional relationship, one variable is always a constant value time the other.

That constant is known as the constant of proportionality.

proportional relationship equation contain (0,0) points

If we put x=0

This  will give us,y=0

If we put x=0, in y=12x

It will give y=0

put if we put x=0 in

y=3x it will give us y=0

hence these two equations represent the proportional relationship.
