Answer:
Mean: 8
Median: 8
Mode: 8
Step-by-step explanation:
Find the average
Mean: 3 + 4 + 5 + 7 + 8 + 8 + 9 + 13 + 15 = 72
Divide by the amount on numbers: 72 / 9 = 8
8 is the average
Find the middle
Median: 3, 4, 5, 7, 8, 8, 9, 13, 15
8 is the middle
Find the most common
Mode: 3, 4, 5, 7, 8, 8, 9, 13, 15
8 is most common
Answer:
x = 7
Step-by-step explanation:
8x = 56
To solve this, we must simplify. To do this, we must divide each side by 8. This, in term, will give us the value of x.
8x = 56
---- ----
8 8
56/8 = 7
x = 7
Our answer is x = 7
3,500,000 - 2,800,000 = 700,000
So the magazine needs 700,000 readers to meet their goal.
Hope that helps you. :-)
Answer:
y = -3x-2
Step-by-step explanation:
the slope can be found using rise/run which comes out to be -3/1 and you can drop the 1 from the fraction to have -3. and then the y-intercept is found from where the line crosses the y-axis
We know that these two angles are equal to each other (There is the "congruent" sign) so we can set them equal to each other and solve for x
3x - 17 = 25 - 3x
(3x + 3x) - 17 = 25 + (-3x + 3x)
6x + (- 17 + 17) = 25 + 17
6x/6 = 42/6
x = 7
Hope this helped!
