I know B is true, but i’m unsure for the other choices.
Answer:
<h3>
a) Mean=1.2</h3><h3>b) The standard deviation is
</h3>
Step-by-step explanation:
<h3>Given that the discrete probability distribution below :</h3><h3><u>Outcome Probability
</u></h3>
0 0.35
1 0.36
2 0.14
3 0.08
4 0.04
5 0.02
6 0.01
<h3>a) To find the mean of this distribution :</h3><h3>The formula is
</h3><h3><u>X P(X) XP(X) </u>
<u /></h3>
0 0.35 0 0
1 0.36 0.36 0.36
2 0.14 0.28 1.12
3 0.08 0.24 2.16
4 0.04 0.16 2.56
5 0.02 0.1 2.5
6 0.01 0.06 2.16

- Now substitute the value in the formula we get
<h3>Therefore Mean=1.2</h3><h3>b) To find Standard Deviation :</h3><h3>The formula is
</h3>
- Substitute the values i the formula we have
<h3>Therefore the standard deviation is
</h3>
Answer: 1 3/4 cups of apples in each batch
Step-by-step explanation:
STEP 1
Writing out the equation to represent if 7 cups of apples make 4 batches One batch is as a result of how many cups of apples
LET x be number of cups of apples to make each batch
7 cups of apples = 4 Batches
x cups of apples = 1 Batch
STEP 2 Solving by cross multiplication
1 batch x 7 cups of apples = 4 batches X x cups of apples
x cups of apples=1 batch x 7 cups of apples / 4batches
x = 7 / 4 = 1 3/4
number of cups of apples to make each batch= 1 3/4
