Answer:
1352
Step-by-step explanation:
Firstly, we get the percentage growth last year. This is calculated as:
(1300-1250)/1250 * 100
= 4%
Now, we are assuming the growth rate is constant. So let’s calculate a 4% growth rate for this year. That would be:
4/100 * 1,300 = 52
The population this year would thus be 1300 + 52 = 1352

<h3>What is Z-score?</h3>
A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
The weight of a randomly selected pack of gum has a z-score of 3.11. Therefore, The weight of this pack of gum is heavier than the mean weight by 3.11 standard deviations.
Hence, the correct option is B.

Step-by-step explanation:
Answer:
150 votes were casted
Step-by-step explanation:
So first, we know that Amy received 48 votes. Then Neil received 1/4 as many votes as Amy. So we can divide 48 by 4:
48/4=12
Neil got 12 votes. We also know that Neil and Amy's votes together is only 40% of the votes casted in total. So we can add their votes together and then find a fifth of the votes casted by dividing the 40% in half:
12+48=60
60/2=30
So now 30 votes are 20% of the total votes casted, now we just have to multiply by 5:
30*5=150
150 votes were casted
