The time it takes for tadpoles to turn into frogs is mound-shaped/symmetric with mean 93 days and standard deviation 8 days. Use the Empirical Rule to estimate the percentage of tadpoles will take longer than 85 days to turn into frogs. Select the single best answer choice. a) approximately 16%
b) approximately 95%
c) approximately 34%
d) approximately 84%
e) at least 95%

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

17.08
