No. It would be negative 5.
Answer:
The slope of the line segment is
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have the points
(2,-5) and (-1, -1)
substitute in the formula
You got divide só see mean, the middle number is the median, range you add all number and divide but how many number has
Answer:
2.7%
Step-by-step explanation:
The probability of rolling the number once is
, and the probability of it happening again is
, so multiply and get
, which is approximately 2.7%
Part a)
The mean height is 69 inches with a standard deviation of 2.5 inches.
If we consider a interval of heights that relies on no more than two standard deviations from the mean, we will cover, approximatelly, 95% of men's heights. Then, we interval that we're looking for is:
Answer: 64 TO 74 INCHES
Part b)
Since [69,74] is half of the interval in the previous answer, we might expect half of 95% as the percentage of men who are in this interval. That is:
Answer: 47.5 PERCENT
Part c)
A interval of heights that relies on no more than one standard deviation from the mean covers, approximatelly, 68% of men's heights. Then, we can consider that the percentage of men that are between 64 and 66.5 inches is given by 47.5 - 68/2 = 13.5.
Answr: 13.5 PERCENT
