Let event A = "math test" and event B = "Score: 90-100." Then find , where
Answers
To find the percentage of students who took the math test and received a grade of 90 or above, we need to calculate the conditional probability P(A ∩ B), which is the probability of event A ("math test") and event B ("Score: 90-100") happening simultaneously.
From the two-way frequency table:
The number of students who took the math test and received a grade of 90 or above is 20.
The total number of students who took the math test is 20 + 40 + 7 = 67.
Now, we can calculate the conditional probability:
P(A ∩ B) = (Number of students who took the math test and received a grade of 90 or above) / (Total number of students who took the math test) × 100%
P(A ∩ B) = 20 / 67 × 100% ≈ 29.85%
So, the percentage of students who took the math test and received a grade of 90 or above is approximately 29.85%.

Let us assume the age of Daniel = x years
Let us assume the age of Kevin = y years
Then
y = 4x
and
y = x + 6
So
4x = x + 6
4x - x = 6
3x = 6
x = 6/3
= 2 years
So
Age of Kevin = 4 * 2 years
= 8 years
A. No. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means.

Answer:
A. No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means.
Step-by-step explanation:
No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means. The central limit theorem says that if we take a large sample (i.e., a sample of size n > 30) of any distribution with finite mean and standard deviation
, then, the sample average is approximately normally distributed with mean
and variance

Unitrate is the quantity of an amount of something at a rate of one or another quantity.
Speed is the rate at which the car is traveling x miles per hour
Speed = Distance / Time
The distance that the car traveled in 7 hours at a speed of 126 miles in 3 hours is 294 miles.
What is a unit rate?
It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
A car traveled a distance of 126 miles in 3 hours.
This can be written as,
126 miles = 3 hours
Multiply both sides by 3.
42 miles = 1 hour
Multiply 7 on both sides.
7 x 42 miles = 7 x 1 hour
294 miles = 7 hours.
This means that,
In 7 hours 294 miles are traveled.
Thus,
The distance that the car traveled in 7 hours at a speed of 126 miles in 3 hours is 294 miles.

If you break down to it's unit rate (126 / 3) you get 42, which is the speed per hour. Now multiply by 7 hours and you get 294 :^]
