He will receive $480 in interest in the first year.
The domain of this function is any x-value that doesn’t cause the denominator to equal zero and cause the function to be indeterminate.
In this case, x cannot be zero, and x cannot be the square root of 5.
Brainliest always accepted! :)
Add 7 to each side to isolate k.
k - 7 ≤ 0
k ≤ 7 is the answer.
Answer: C
Step-by-step explanation: 3x and 5x both have x
Answer:
9.5
Step-by-step explanation:
Find the sample variance for the data 9,12,9,14,6. Round the answer to one decimal place. Sample variance.
Step 1
We find the Mean of the numbers
Mean = Sum of terms/ Number of terms
Mean = 9+12+9+14+6/5
= 50/5
= 10
Step 2
We find the sample variance
Formula =
(x - Mean)²/n - 1
n = 5
= (9 - 10)²+(12 -10)²+(9- 10)²+(14-10)²+(6-10)²/5 - 1
= 1+ 4+ 1+ 16+16/5 - 1
= 38/5 - 1
= 38/4
= 9.5
Therefore, Sample variance = 9.5
