Is this correct? I used the 90/360 x 2 π (90)
slavikrds [6]

The circumference is found by multiplying the radius by pi by 2

And then the arc length would be multiplied by the fraction of the circle..

So using what you wrote is correct, but the answer you got is incorrect.

2x 3.14 x 90 = 565.2 meters

565.2 x 90/360 = 141.3 meters

Denise is a professional swimmer who trains, in part, by running. she would like to estimate the average number of miles she run
SSSSS [86.1K]
Given:
n = 20, sample size
xbar = 17.5, sample mean
s = 3.8, sample standard deiation
99% confidence interval

The degrees of freedom is 
df = n-1 = 19

We do not know the population standard deviation, so we should determine t* that corresponds to df = 19.
From a one-tailed distribution, 99% CI means using a p-value of 0.005.
Obtain
t* = 2.8609.

The 99% confidence interval is
xbar +/- t*(s/√n)

t*(s/√n) = 2.8609*(3.8/√20) = 2.4309
The 99% confidence interval is
(17.5 - 2.4309, 17.5 + 2.4309) = (15.069, 19.931)

Answer: The 99% confidence interval is (15.07, 19.93)

Graph the relation and it's inverse. Use open circles to graph the points of the inverse
joja [24]

Step-by-step explanation:

We are given a set of points (0,3), (4,2), (9,7) and (10,-1) representing a function.

It is required to graph the function and its inverse.

As we know that, the inverse of a function is reflected by y=x line on the graph.

So, in order to find the inverse we have to replace the co-ordinate (x,y) by (y,x).

Then the points (3,0), (2,4), (7,9) and (-1,10) represents the inverse of the function.

So, after plotting all the points of the function and its inverse, we get the following graph, where figure 1 is of the function and figure 2 is of its inverse.
