The price of a zazio camera at a national chain store is $181. a new statistics student decided to test the hypothesis that you can buy that same camera online for less than you can buy it at the chain store. he decided to test it at a level of significance of .05 since that level is the most common level. he looked up the price of that camera on 10 different websites. here are the prices that he found: 157 181 177 183 157 181 182 177 163 177What is the null hypothesis? (Remember that the null hypothesis contains an equal sign.)

-4

step-by-step explanation:

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

stop cheating

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
