Answer:
b) 36.
Step-by-step explanation:
Justicemoya35 has an excellent answer, but I will provide a slightly different approach!
According to the word problem, the box contains 60 apples.
If 40% of the apples are red, then 60% of the apples are green.
As I mentioned before, there are 60 apples; 60% of the 60 apples are green.
This means we have the find 60% of 60.
We can find the percentage of a number by using this formula:
60% OF 60
Now that I've correctly set up the problem, we cross multiply, then divide the products.
Therefore, 36 apples are red.

Answer:
y=1x+11
Step-by-step explanation:
1. Find the slope of the given points
2. Pick any point to find the y-intercept
(3, 14)
x=3, y=14, m=1
3. Substitute
y=mx+b
14=1(3)+b
14=3+b
14-3=b
11=b
4. Write the linear function rule
y=mx+b
y=1x+11
Using the Central Limit Theorem, it is found that since the sample size is greater than 30, a normal approximation can be used, hence the test can be made.
<h3>Central Limit Theorem</h3>The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
In this problem, the distribution of lengths is skewed, however, since the sample size is of 100 greater than 30, a normal approximation can be used, hence the test can be made.
