Answers
Answer:
12.5
Step-by-step explanation:
10, 8, 14, 16, 13, 12
Organize the numbers from least to greatest
8, 10, 12, 13, 14, 16
Normally, the median would just be the number in the middle. However, because there are two numbers in the middle for this data set, add them and divide the sum by 2.
12+13=25
25÷2=12.5
Therefore, the median is 12.5.

Garret invested $12,000 at an annual interest rate of 6%. How much money would Garret have had to invest at 10% so that the combined interest rate for both investments was 7% over the year?
Answers
Step-by-step explanation:
To determine how much money Garret would have had to invest at 10% in order to achieve a combined interest rate of 7% over the year, we can set up the following equation:
(12000 * 0.06) + (x * 0.10) = (12000 + x) * 0.07
Let's solve this equation to find the value of 'x', which represents the amount Garret would have had to invest at 10%:
720 + 0.10x = 0.07(12000 + x)
Simplifying the equation:
720 + 0.10x = 840 + 0.07x
0.10x - 0.07x = 840 - 720
0.03x = 120
x = 120 / 0.03
x = 4000
Therefore, Garret would have had to invest $4,000 at a 10% annual interest rate in order to achieve a combined interest rate of 7% over the year.

What is (-3, -14) and (0, -9) written in slope intercept form? Thank you!
Answers
Answer:
Y= 5/3x + -9
Step-by-step explanation:
Well its
y=mx+b
m is slope
B is y intercept
To fidn y intercept, just make sure the X value of any coordiante given is 0 and the y value is not 0. So basically anything with (0, y), thats your y intercept.
Slope Is just
(y2-y1) / (x2-x1)
Answer:
y = 5/3x - 9
The equation for slope-intercept form would be y = mx + b.
Where y would be the total, m would be the slope, and b would be the y-intercept.
Find the volume of a prism with a length of 4.5 inches, width of 5 inches, and a height that is one third of the length.
Answers
Answer:
33.75
Step-by-step explanation:
Formula: Width · Height · Length
Substitute with known values: 5 · height · 4.5
Find Length: Since the height is one third of the length, we need to divide the length by three → 4.5 ÷ 3 = 1.5
Know we know that the height is 1.5.
Substitute Known Height: 5 · 1.5 · 4.5
Simplify: 5 · 1.5 · 4.5 = 33.75
