What is the standard deviation of the data? A statistics student gave a survey to students which
asked how many first cousins they have. The data from
the first nine responses are shown below.
0 2.38 first cousins
0 2.52 first cousins
6, 2, 7, 8, 8, 8, 5, 10, 10
O 5.65 first gausins
SARE
6.36 first cousins

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

the correct answers i think are b. and d.

give me brainliest if it is correct!

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
