Answer:
Step-by-step explanation:
f(3) = 8^3 + 7 = 512 + 7 = 519
Answer:
120
Step-by-step explanation:
Answer: - (2 + 3) = -5
<u>Step-by-step explanation:</u>
When combining numbers that have the same sign, you add them and then include the sign.
For example:
-2 - 3 = -(2 + 3) = -5
-6 - 5 = -(6 + 5) = -11
-7 - 8 = -(7 + 8) = -15
Answer:
y = 2x - 3
Step-by-step explanation:
Parallel lines have the same slope
only the constant changes
y = 2x + b
To find "b"
Plug in point (3, 3)
3 = 2(3) + b
3 = 6 + b
Subtract 6 from both sides
-3 = b
The equation for the parallel line is
y = 2x - 3
Mean: add all numbers together and divide by the amount of numbers there are.
8 + 9 + 8 + 11 = 36
36/4 = 9
mean = 9
Median: Find the middle number. Since in this case it has an even amount of numbers, add the two middle numbers and divide by 2
8 + 9 = 15
15/2 = 7.5
median = 7.5
Mode: The number that shows up the most
Mode = 8
Range: Subtract the smallest number from the largest number
11 - 8 = 3
Range = 3
hope this helps
