Answer:
x = 9
Step-by-step explanation:
0.09+27/100=x/100+27/100
0.09=x/100
9=x
Given Information:
number of trials = n = 1042
Probability of success = p = 0.80
Required Information:
Maximum usual value = μ + 2σ = ?
Minimum usual value = μ - 2σ = ?
Answer:
Maximum usual value = 859.51
Minimum usual value = 807.78
Step-by-step explanation:
In a binomial distribution, the mean μ is given by
μ = np
μ = 1042*0.80
μ = 833.6
The standard deviation is given by
σ = √np(1 - p)
σ = √1042*0.80(1 - 0.80)
σ = √833.6(0.20)
σ = 12.91
The Maximum and Minimum usual values are
μ + 2σ = 833.6 + 2*12.91
μ + 2σ = 833.6 + 25.82
μ + 2σ = 859.51
μ - 2σ = 833.6 - 25.82
μ - 2σ = 807.78
Therefore, the minimum usual value is 807.78 and maximum usual value is 859.51
Answer:
For me the answer is
The ratio for the percent increase has a smaller denominator than the percent decrease.
Step-by-step explanation:
From 45 to 75, the increase is 30
If we check the % increased, (30/45)*100 = 66.667%
If we decrease the price from 75 to 45, the amount is same, i.e. 30 but the denominator is changed.
(30/75)*100 = 40%
Answer:
5
Step-by-step explanation:
You need to first add up all the berries: 2+2+5+7+9 which is 25.
There are 5 people so you need to divide 25 by 5: 25÷5 which is 5
So each person will have 5 berries each.
