Answer:
x=-11/8
Step-by-step explanation:
First use the Distributive property on [3(2x-1)]:
5x+6x-3=3x-14
Now combine alike terms:
11x-3=3x-14
Now add three to both sides:
11x=3x-11
Now subtract 3x from both sides:
8x=-11
Now divide both sides by 8:
x=-11/8
This fraction cannot be simplified meaning your final answer SHOULD be -11/8
Answer:
2.5% of IQ scores are no more than 65
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 = 95
Standard deviation = 15
Using the empirical rule, what percentage of IQ scores are no more than 65?
65 = 95 - 2*15
So 65 is two standard deviations below the mean.
By the Empirical Rule, 95% of the measures are within 2 standard deviation of the mean. Of those 5% which are not, 2.5% are more than 2 standard deviations above the mean and 2.5% are more than 2 standard deviations below the mean.
So 2.5% of IQ scores are no more than 65
Your answer is 6%
because 6% =0.06 x 750 =45
45x 5 (years)=225
