Answer:
68.26% corresponds to the life span of fruit flies that are between 29 days and 37 days
Step-by-step explanation:
Given that the life span of a species of fruit fly have a bell-shaped distribution, with a mean of 33 days and a standard deviation of 4 days.
Let X be the life span
X is N(33,4)
we can convert X into Z standard normal variate by
To find the percentage corresponds to the life span of fruit flies that are between 29 days and 37 days
For this let us find probability for x lying between 29 and 37 days
Probability = P(|z|<1) = 0.6826
Convert to percent
68.26% corresponds to the life span of fruit flies that are between 29 days and 37 days

Answer:
smaller number = 623
middle number = 625
larger number = 627
Step-by-step explanation:
Variable: X = smallest number
If these numbers are consecutive and odd, then the numbers would be:
x, x+2, x+4
x + (x + 2) + (x + 4)= 1875
3x + 6 = 1875
3x = 1869
x = 623
x + 2 = 625
x + 4 = 627
Check:
623 + 625 + 627 = 1875

hope it helps you........
Answer:
To find the answer consider that this is a right triangle and we can use the tangent function in order to find the value of x
remember the acronym soh cah toa.
to use the tangent function we divide the opposite and adjacent side that is what the oa stands for in toa
setting it up looks like this
tan 72° = 
solving for x gives us x= 8×tan 72°
which is about 24.62
