Answer:
5.88%
Step-by-step explanation: Change= (((90-85))/85)*100
=5.88%
$18.725 ; not sure if you want to round it to the nearest hundredths but if you take the original price and the tax rate you'll get: $17.50 then you take that and multiply it by 0.07.
105 = 67 + x
x = 105 - 67
x = 38
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
Answer:
non linear
Step-by-step explanation:
because it isn't solved yet. x needs its value to continue.
