($40768/y)(y/52w)=$784/week
Seven hundred and eighty-four dollars per week.
Answer:
w = 80/9 ft.
L = 640/9 ft.
Step-by-step explanation:
L = length w = width
2w = L/4 so 8w = L
160 = 2L + 2w
160 = 2(8w) + 2w
160 = 16w+2w
160 = 18w
80/9 = w
Answer: 6.25 miles
On Friday Hakeem ran 6.25 miles.
Based on the one-sample t-test that Mark is using, the two true statements are:
- c.)The value for the degrees of freedom for Mark's sample population is five.
- d.)The t-distribution that Mark uses has thicker tails than a standard normal distribution.
<h3>What are the degrees of freedom?</h3><h3 />
The number of subjects in the data given by Mark is 6 subjects.
The degrees of freedom can be found as:
= n - 1
= 6 - 1
= 5
This is a low degrees of freedom and one characteristic of low degrees of freedom is that their tails are shorter and thicker when compared to standard normal distributions.
Options for this question are:
- a.)The t-distribution that Mark uses has thinner tails than a standard distribution.
- b.)Mark would use the population standard deviation to calculate a t-distribution.
- c.)The value for the degrees of freedom for Mark's sample population is five.
- d.)The t-distribution that Mark uses has thicker tails than a standard normal distribution.
- e.)The value for the degrees of freedom for Mark's sample population is six.

Answer:
A
Step-by-step explanation:
Two events are termed to be mutually exclusive if they cannot happen at the same time. This means that the probability of occurring at the same time is zero.
A is correct.
The probability of the two events happening at the same time is zero
B is incorrect
The probability of both happening at the same is not equal to the probability of B alone
C is incorrect
The probability of the union of the two is never equal to zero since they might occur at different times
D. Is incorrect
The probability of both happening at the same time is never equal to the probability of A alone
