First, lookup a standard normal table and see what the z-score is for 0.025 (one half of 100% - 95%) to allow for equal sized tails. You should find that the z-score is 1.96. That means that 95% of the time, the value should be within 1.96 standard deviations of the mean. Now let's calculate the standard deviation.
800 is 800 - 1200 = -400 to the left of the mean of 1200.
1600 is 1600 - 1200 = 400 to the right of the mean of 1200.
So we are an equal distance of 400 on both sides of the mean. And we know from the z-score of 1.96, that we're 1.96 standard deviations from the mean. So a little division will give us the standard deviation. Which is:
400 / 1.96 = 204.0816327
So the standard deviation of the light bulbs is 204</span>
The first step to solve this question is to find out what 5/6 of 54000 is. So we multiply 5/6 by 54000. Why? Because there's the word "of" and "of" is usually associated in multiplication. So:
5/6 × 54000 = 45000.
So now we know that 5/6 of 54000 is 45000. So it means that she needs 45000 from senior citizens. But the question doesn't stop there, it also asks us to solve for the amount of votes she needs to win other than senior citizens.
Now we know that 45000 seniors need to vote for her we subtract 45000 to the total amount which is 54000.
54000 - 45000 is 9000.
So it means that she needs 9000 voters other than senior citizens to win the election for city council.
Answer:
Cole has 15 pencils.
Step-by-step explanation:
First, we have the equation c + o =18, c representing cole, and o representing connor.
From there, we get 5o=c
Using substitiution, we get o=3
5(3)=15
15+3=18
