Question 1 3 pts
An independent random sample is selected from an approximately normal population with an unknown
standard deviation. Find the p-value for the given sample size and test statistic (assume one-sided), n-11,
T-1.91. Round to three places. If using R, use the following command: pt(t-value, degrees of freedom).

step-by-step explanation:

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
