Answer:
4(x^2+5) that's ur answer I did it in 2 steps
Step-by-step explanation:
Subtract 27-7 and u get 4x^2+20.
Now factor and u get 4(x^2+5)
21.19%
First you need to find the z-score with
X- Mean
----------- = Zscore
Standard
Deviation
Then use your z table (should be on your formula sheet if not look one up)
to find your proportion (in this problem it would be .2119) and convert it to a percent.
So plug everything in
6.64-7.2
------------ = Z-Score
.7
Z-Score= 0.8
The table showed our proportion to be .2119
therefore your percent is 21.19%
Answer:
I ≈ 251188643
Step-by-step explanation:
Given
R = logI [ note log I = 
I ]
Using the rule of logarithms
x = n ⇒ x = 
Substitute R = 8.4 into the equation, then
logI = 8.4
I = 
≈ 251188643
The answer is going to be b
Answer:
C is true.
Step-by-step explanation:
If you look at the model, the middle line in the box means the median and it is 7 so yeah! Hope this helped! Good Luck! :)
