You would need to distribute the 3t to the value in the parentheses to make the expression, aka answer, 12t^2-3t
B. 1/27
1. you switch the denominator and the numerator (3/1 goes to 1/3).
2. then you take the exponents value (3) and put that as the exponent for 1/3
3. 1/(3^3) = 1/27
Answer:
x=8
Step-by-step explanation:
The side G-F is the same side as side Q-R so 2 times 8 is 16
and 16 - 4 is 12
so x=8
Answer:
oh um thank you
Step-by-step explanation:

Answer:
The student's score closest to 91 percentile.
Step-by-step explanation:
Since the scores on the standardized test are approximately normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 480
σ = 90
If a student has a score of 600, then x = 600
For x = 600,
z = (600 - 480)/90 = 1.33
Looking at the normal distribution table, the probability corresponding to the z score is 0.91
the student's score closest to 91 percentile.
