For the first letter drawn, there are no conditions/restrictions we need to consider. So, the number of ways to draw an i is:
For the second draw, the i is not replaced. That means, we've shrunk the sample space because we're dealing with less elements for the second draw. Firstly, one i disappears since we picked an "i" and there are 10 elements left, not 11.
Thus, to draw the second i, we have:
Answer:
d
Step-by-step explanation:
Answer:
The weight of pears is 3.08 kg
Step-by-step explanation:
A farmer sells 7.7 kilograms of apples and pears.
3/5 of this weight is apples.
This means that the weight of apples is:
3/5 of 7.7
=>
The weight of apples is 4.62 kg.
The weight of pears will therefore be:
The weight of pears is 3.08 kg.
Answer:
1067
Explanation:
The formula that will be used to calculate the sample size if population proportion isn't given is expressed as;
Sample size n = |Z|² × 0.25/E² where;
Z is the z-score at 95% confidence
E is the margin of error
Given parameters
Z score at 95% confidence interval = 1.96
E = 0.03
Substituting the given values into the formula to get the sample size n we will have;
n = 1.96²×0.25/0.03²
n = 3.8416×0.25/0.0009
n = 0.9604/0.0009
n = 1067.11
n ≈ 1067
Hence, the minimum sample size required to estimate a population proportion is approximately 1067
The equation ln 5 = y as an exponential equation is
<h3>How to rewrite the expression?</h3>
The natural logarithm equation is given as:
ln 5 = y
Rewrite as:
ln(5) = y
Take the exponent of both sides
Evaluate the expression
Rewrite as:
Hence, the equation ln 5 = y as an exponential equation is
