Answer:33.3
Step-by-step explanation: a mile is 1000×3 so it's 3000/90
1/4 hour = 4 1/4 miles
Change to improper fraction:
1/4 hour = 17/4 miles
Multiply by 4 on both sides:
1 hour = 17 miles
Answer: Ramon rides his bike at 17 miles/hour.
Fill the 200mL beaker all of the way. Using the water in that beaker, fill and pour out the 30mL twice and the 40mL three times. You should be left with 20mL in the 200mL beaker.
Answer: The domain is
and the range is
.
Step-by-step explanation:
The domain is the set of x-values and the range is the set of y-values.
Using the Central Limit Theorem, nothing can be stated about the shape of the sampling distribution for the sample mean, as the sample size is less than 30.
<h3>What does the Central Limit Theorem state?</h3>
It states 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, we have a skewed variable and n < 30, hence nothing can be stated about the shape of the sampling distribution for the sample mean.
