Answer:
C. 45 and 141 seconds
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 = 93 seconds
Standard deviation = 16 seconds
99.7% of running times are approximately between:
By the Empirical rule, within 3 standard deviations of the mean, so between 3 standard deviations below the mean and 3 standard deviations above the mean
3 stnadard deviations below the mean
93 - 3*16 = 45 seconds
3 standard deviations above the mean
93 + 3*16 = 141 seconds
The correct answer is:
C. 45 and 141 seconds
Answer: f=26
Step-by-step explanation: x^2+6x^2+12x+7/x= 26
There are four properties involving multiplication that will help make problems easier to solve. They are the commutative, associative, multiplicative identity and distributive properties. Multiplicative Identity Property: The product of any number and one is that number. For example 5 * 1 = 5.
Answer:
A
Step-by-step explanation:
the answer is A. if you notice the y-intercept, it its at -5
A is the only answer choice that gives -5 as the y-intercept
another way to make sure that A is the right answer is to calculate the slope
when you increase 3 units UP (y), you increase 5 units to the RIGHT (x)
since slope is y/x, it should be 3/5 which is also in A
another way to check A is to plug in points
hope this helps!
