Answer:
The answer is below
Step-by-step explanation:
a) For a normal model the sample size has to be equal or greater than 30 so that it can be a normal distribution.
b) Given that:
μ = 11.2 minutes, σ = 4.8 minutes, n = 45
The z score determines how many standard deviations the raw score is above or below the mean. It is given by:
For x < 10 minutes
Therefore from the normal distribution table, P(x < 10) = P(z < -1.68) = 0.0465
Answer:
35 and 55
Step-by-step explanation:
x+(2×-15)=90
3x-15=90
3x=105
x=35
other angle is 35×2-15=55
Answer:89%
Step-by-step explanation: its the probability that they will get anything other than an arm tattoo. So you subtract 43 from 389 and it gives you 346,
346/389 x 100% = 88.9%
Answer:
Step-by-step explanation:
Translating a function up is very simple, all you need to do here is add 8.
If you want to think of it logically,
the whole right side of the function here can be our output. If x is 8, then the output, or height, is also 8. if you wanted to translate that up to 10, you'd simply need to add 2 to it, meaning 
. Then, at any given point on the function, it'd be 2 higher than it would be otherwise.
The Answer is (D. No solution)
