Y=1/3x+5 i believe is your answer if im wrong please correct me
sorry i read the line wrong
Answer:
Step-by-step explanation:
Acres of corn harvested : time taken = 8 3/4 : 5/6
How much corn can she collect in a hour. ?
Let
x = Acres of corn harvested
Acres of corn harvested : time taken = x : 1
8 3/4 : 5/6 = x : 1
35/4 : 5/6 = x : 1
35/4 ÷ 5/6 = x/1
35/4 × 6/5 = x/1
35*6/4*5 = x/1
210/20 = x/1
210 * 1 = 20 * x
210 = 20x
x = 210/20
= 10 1/2 acres
x = Acres of corn harvested = 10 1/2 acres

Step-by-step explanation:
Using the binomial distribution, it is found that:
a) The expected number of shots until he misses is of 5.
b) You expect him to make 12 shots.
c) The standard deviation is of 1.55 shots.
<h3>What is the binomial probability distribution?</h3>
- It is the <u>probability of exactly x successes on n repeated trials, with p probability of a success on each trial.</u>
The expected number of trials until q failures is:
![E_f(X) = \frac{q}{1 - p}](https://tex.z-dn.net/?f=E_f%28X%29%20%3D%20%5Cfrac%7Bq%7D%7B1%20-%20p%7D)
The expected value of the binomial distribution is:
![E(X) = np](https://tex.z-dn.net/?f=E%28X%29%20%3D%20np)
The standard deviation of the binomial distribution is:
![\sqrt{V(X)} = \sqrt{np(1-p)}](https://tex.z-dn.net/?f=%5Csqrt%7BV%28X%29%7D%20%3D%20%5Csqrt%7Bnp%281-p%29%7D)
In this problem:
- A basketball player has made 80% of his foul shots during the season, hence
.
Item a:
- Miss one shot, hence one failure, that is,
.
![E_f(X) = \frac{1}{0.2} = 5](https://tex.z-dn.net/?f=E_f%28X%29%20%3D%20%5Cfrac%7B1%7D%7B0.2%7D%20%3D%205)
Item b:
- The player takes 15 shots, hence
.
![E(X) = np = 15(0.8) = 12](https://tex.z-dn.net/?f=E%28X%29%20%3D%20np%20%3D%2015%280.8%29%20%3D%2012)
Item c:
![\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{15(0.8)(0.2)} = 1.55](https://tex.z-dn.net/?f=%5Csqrt%7BV%28X%29%7D%20%3D%20%5Csqrt%7Bnp%281-p%29%7D%20%3D%20%5Csqrt%7B15%280.8%29%280.2%29%7D%20%3D%201.55)
