Recall the jumping paper frogs experiment. Suppose that a 95% confidence interval for the average jump distance of frogs made from construction paper is (8.8104, 11.1248)cm. Also suppose that the sample size is 89. What is the sample mean and sample standard deviation for the jump distance of such frogs in this experiment?

- 1.613 = -1.6 or -1.61

-1.522 = -1.5 or -1.52

0.587 = 0.6 or 0.59

3.079 = 3.1 or 3.08

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
