Step-by-step explanation: Have a nice day bro!✌️
Answer and explanation:
Null hypothesis: p is not 54%
Alternative hypothesis : p is equal 54%
First find standard deviation
Standard deviation is:
σ = √[ P ( 1 - P ) / n ] = √[ 0.54×0.46/220 ] =0.033
The z score is calculated p-P/σ = (0.54-0.50)/0.033 = 1.2121
Therefore we can conclude that proportions are not same and fail to reject the null hypothesis
Answer:
16%
Step-by-step explanation:
so you already know 35% like both and 17% like apples and 32% like neither
add those and get 84. we know that the percent is over 100 . So far you have 84% meaning there is only 16% left . Therefore 16% like bananas
Answer:
- C. P’s surface area is greater than Q’s surface area.
Step-by-step explanation:
<em>Refer to attached</em>
With a corner removed, it doesn't change surface area of the cube as same area is exposed equal to the area of 3 small faces.
With the corner relocated to the top of the cube, it covers the area of one small face but adds up small 5 faces (4 sides and one top). In total the P has more surface area than the Q.
Correct answer choice is C.
Answer:
- x = 3
- y = 4.
- There are infinite solutions. I'll just give you this solution.
Step-by-step explanation:
<u>Given equation:</u>
<u>Solve for variables:</u>
- 7 - x = y
- 7 - 3 = 4
- 7 - y = x
- 7 - 4 = 3.
