95% confidence level. Using two sample t-test(not a z test) find the margin of error, confidence interval, & sample standard deviation for the data set below. 6935, 6948, 7130, 7089, 8925, 7040, 9067, 9210, 9111, 9321, 9231, 7073, 7179, 6943, 7051, 6971, 7051, 6982,6900, 6937, 7036, 9513, 11738, 10420, 10840, 11566, 10575, 11189, 11375, 11077​

after simplifying it i got: -36.25 as my answer. hope that !

ab will be equal to

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
