Answer:
5^14
Step-by-step explanation:
We use the laws of indices:
When there is a power outside the bracket multiply the powers.
(a^m)^n=a^m×n
So (5^7)^2=
5^7×2
5^14
Answer:
82
Step-by-step explanation:
Given that the population mean μ=86 and standard deviation σ=4 then one standard deviation below the mean means 4 less than 86 which is 82.
or
One standard deviation below the mean means z=-1 where z* is the z*score value in the standard normal distribution
Apply the formula
z=(x-μ)/σ
where x=Alice's score
μ=estimate mean
σ=standard deviation
z=(x-μ)/σ
-1=(x-86)/4----------------cross multiply
-1*4=x-86
-4=x-86
-4+86=x
82=x
The second one I hope I am correct
Answer:
Step-by-step explanation:
If you use pemdas, you would do 3÷1/3 which equals 9. Then do 9-9, which equals 0. Then, do 0+1, which equals 1. Hope this helps! <3
