Using the Central Limit Theorem, it is found that the sampling distribution of the sample proportion of the 50 questions on which you get the correct is approximately normal, with mean of 0.7 and standard error of 0.0648.
<h3>What does the Central Limit Theorem state?</h3>
It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean
and standard deviation
, as long as
and
.
In this problem, we have that p = 0.7, n = 50, hence the mean and the standard deviation are given as follows:

Answer:
x = -2
y = 7
Step-by-step explanation:
x = 12 - 2y
7(12 - 2y) + 4y = 14
84 - 14y + 4y = 14
84 - 10y = 14
10y = 70
y = 7
x = 12 - 2 x 7
x = 12 - 14
x = -2
So, we need to divide the reward into 5 parts, then award 2 parts to Jaden and 3 parts to Cadence.
$140 / 5 = $28
Jaden gets 2 * 28 = $56
Cadence gets 3 * 28 = $84
$56 + $84 = $140
The Area of the lawn is:
20m x 14m = 280m^2
The Area of the Circle is:
pi x 5^2 = 78.54
280 - 78.54 = 201.46m^2
Answer:
5.4
Step-by-step explanation:
First work out 4/9 this is the same thing as 4 ÷ 9 which equals 0.44444
and then add the whole number 5 so,
5 + 0.44444 = 5.44444
