Answer:
115 mg
Step-by-step explanation:
The 50th percentile has a corresponding z-score of z = 0. The z-score, for any given value of caffeine, X, is given by:
Therefore, if z=0, then X must be equal to the mean value of the normal distribution, which is 115 mg. Thus, the 50th percentile value of caffeine content is 115 mg.
Step one: 46/100
Step two:46/100=23/50
Answer:
The correct answer is distributive postulate.
Step-by-step explanation:
Look at the expression we have given:
3x + 3 = 3(x + 1)
And we are asked that which postulate is illustrated for the real numbers.
We know that the distributive property of multiplication states that we can multiply a sum of numbers by multiplying each addend separately and finally add the products.
a*(b+c)= a*b+a*c
where a,b and c are real numbers.
3(x+1)= 3*x+3*1 = 3x+3
Therefore the correct option is distributive postulate....
Answer:
(5,-9)
Step-by-step explanation:
Find the symmetry axis of f(x) and substitute
Answer:
5
Step-by-step explanation:
One step equation. You would subtract 7 from 12 to get 5 because x would be alone now.
