Answer:
7()=11
8()=42
I could barely see the answer for number 9 sorry :(
Step-by-step explanation:
the 7() is 2(3)+5
2(3)=6
6+5=11
Question (8)
c^2+3a x b
c(6)^2+ 3(3) x 2/3
36+9 x 2/3
36+6=42
So,, there are 5 different flavors. A total of 180 people were asked. Hence, the hypothesis that there is no significant difference is that every flavor gets 180/5=36 flavors. x^2=
![\sum{\frac{(x_i)^2}{m_i}}-n](https://tex.z-dn.net/?f=%5Csum%7B%5Cfrac%7B%28x_i%29%5E2%7D%7Bm_i%7D%7D-n)
. In this case, mi is the proportion of the hypothesis, thus 36, n=180 and xi is the number of actual observations. Substituting the known quantities, we get that x^2=9. The degree of association is given by
![\sqrt{X^2}/ \sqrt{N(n-1)}](https://tex.z-dn.net/?f=%20%5Csqrt%7BX%5E2%7D%2F%20%5Csqrt%7BN%28n-1%29%7D)
. This yields around 0.10, much higher than our limit.
Answer: d
Step-by-step explanation:
Find the area of the rectangle.
![A=l*w\\A=(15in)(12in)\\A=180in^2](https://tex.z-dn.net/?f=A%3Dl%2Aw%5C%5CA%3D%2815in%29%2812in%29%5C%5CA%3D180in%5E2)
Find the area of the base of the semicircle.
![A=\pi r^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2)
12 in would be the diameter, divide by 2 to get the radius.
![\frac{12}{2}=6](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B2%7D%3D6)
Plug this into the formula.
![A=(3.14)(6)^2\\A=113.04in^2](https://tex.z-dn.net/?f=A%3D%283.14%29%286%29%5E2%5C%5CA%3D113.04in%5E2)
Since we do not have a full circle but a semi one instead, we must divide our result by 2.
![\frac{113.04}{2}=56.52in^2](https://tex.z-dn.net/?f=%5Cfrac%7B113.04%7D%7B2%7D%3D56.52in%5E2)
Add both areas.
180+56.52=236.52![in^2](https://tex.z-dn.net/?f=in%5E2)
