Answer:
1.5x4=6 so thats 4 so you times 2.5 x3 which is 7.5 so the answer is 10.
Step-by-step explanation:
Answer:
Point B is the result of a 90° counterclockwise rotation.
Step-by-step explanation:
If something is reduced by 12%, it must only be worth 88% of what it once was.
88% of P = 132.88
.88 * P = 132.88
P = £ 151
No.
The relation is proportional when it can be written as
y = kx
As soon as you add a constant, you destroy the proportionality.
Answer:
99.7% of the students have grade point averages that are between 1.42 and 3.7
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 2.56 and standard deviation of 0.38.
Using the empirical rule, what percentage of the students have grade point averages that are between 1.42 and 3.7?
1.42 = 2.56 - 3*0.38
3.7 = 2.56 + 3*0.38
So both these scores are within 3 standard deviations of the mean, which means that 99.7% of the students have grade point averages that are between 1.42 and 3.7
