Answer:

a. Jean, because her commute is in the country.

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In this question:

Whoever has the higher z-score will have the longer commute.

Mary:

Travels for 35 minutes. In big cities, average commutes are 40 minutes with a standard deviation of 15 minutes. This means that [tex]X = 35, \mu = 40, \sigma = 15[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{35 - 40}{15}[/tex]

[tex]Z = -0.33[/tex]

Jean:

Travels for 30 minutes. In rural areas, the average commute is 25 minutes with a standard deviation of 6 minutes. This means that [tex]X = 30, \mu = 25, \sigma = 6[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{30 - 25}{6}[/tex]

[tex]Z = 0.83[/tex]

Due to being in the Country, Jean's z-score is higher, so her commute is longer. The correct answer is given by option A.

The true statement is (a) Jean, because her commute is in the country.

For Mary, we have the following parameter:

x = 35 minutes from  the city

For Jean, we have the following parameter:

x = 30 minutes from  the county

The z-score is calculated as:

[tex]z = \frac{x - \bar x}{\sigma}[/tex]

For the city, we have:

[tex]\bar x = 40[/tex]

[tex]\sigma = 15[/tex]

So, the z-score of Mary is:

[tex]z = \frac{35 - 40}{15} = -0.33[/tex]

For the country, we have:

[tex]\bar x = 25[/tex]

[tex]\sigma = 6[/tex]

So, the z-score of Jean is:

[tex]z = \frac{30 - 25}{6} = 0.83[/tex]

0.83 is greater than -0.33

Hence, Jean has a longer commute

Answer:

This does not matter

Step-by-step explanation:

This does not matter and does not affect her finance charge. What does affect this charge is whether or not she pays what is owed on time. Meaning that she must pay everything that she owes between the end of the billing cycle and the day that the payment is due. In this scenario, it seems that she can only afford to pay half of what she actually owes, therefore regardless of when she pays this amount her finance charge will increase until she pays the entire debt.

Answer:

1. 363 to 2

2. 363:2

3. 363/2

Step-by-step explanation:

1. First of all, there are 365 days in a year.

* Note that the question says there are only 2 days where sports aren't played.

2. As said in the question there are 3 ways to write a ratio: a to b; a : b; a/b. Now, let's think that what are a and b in this scenario? a= says without games= 2; and b= days in a year= 365.

3. Now fill in the variables with the numbers for each form of a ratio.

a. 363 to 2

b. 363:2

c. 363/2

Hi there!

[tex]\large\boxed{-12,600 N}[/tex]

Recall that the equation to calculate force is:

F = m · a where m = mass, a = acceleration, and F = net force.

Since we are given the velocity, and time needed to stop, we can calculate the acceleration using the following kinematic equation:

vf = vi + at

The initial velocity is 36 m/s and the final velocity is 0 m/s, therefore:

0 = 36 + at

Move 36 to the other side and plug in the given time:

-36 = 4a

Divide both sides by -4 to find a:

-36/4 = a

a = -9 m/s².

Since the acceleration is -9 m/s² and the mass is 1400 kg, use the above force equation to solve:

F = -9 × 1400 = -12600 N. (negative refers to the force working in the opposite direction of the car's travel. If simply needing the magnitude of the force, it would be 12600 N)
