Step-by-step explanation:

Vicky's Gross Monthly Income for the job at Southside High School is $3708.33.

Gross income of an individual is the income he/she receives before deduction and taxes.

Given that,

Base salary per year = $43,600

Income for coaching JC softball = $900

Free life insurance coverage = $15,000

Health & dental or medical premiums = $78/month

Gross income is the income an employee receives before all the deductions.

Insurance premiums are deducted from the base salary. So it is not included in gross income.

Annual Gross income = $43,600 + $900 = $44,500

Monthly Gross Income = $44,500 / 12 = $3708.33

Hence the monthly gross income is $3708.33.

Option B is correct.

Stephanie should add Jim to her health care plan.

Step-by-step explanation:

Let's take the options one by one.

Option 1

If Jim's employers insure him and his wife.

Jim’s employer pays 42% of his $378 monthly premium. His insurance plan will also pay for 23% of the $345 premium for additional beneficiaries.

It means Jim will pay (0.58 of $378) for himself plus (0.73 of $345) for his wife.

Amount Jim pays = (0.58 × 378) + (0.73 × 345) = $471.09

Option 2

If Stephanie's employers insure both of them.

Stephanie’s employer pays 35% of her $298 monthly premium but offers to pay an extra 10% of her premium for each beneficiary Stephanie adds to her plan. Her employer would then pay 30% of the $349 premium for each additional beneficiary.

It means Stephanie would pay (0.65 of $298) she'll pay for herself plus (0.70 of $349) she'll pay for her husband minus (10% of $298) that her company wants to pay out of the insurance fee of any of her additional beneficiary.

Amount Stephanie will pay = (0.65 × 298) + (0.70 × 349) - (0.10 × 298) = $408.2

Option 3

If each of them does an insurance plan with their respective employers

Jim’s employer pays 42% of his $378 monthly premium.

Stephanie’s employer pays 35% of her $298 monthly premium

Jim would pay (0.58 × $378) for himself = $219.24

Stephanie would pay (0.65 × $298) for herself = $193.7

Total they would pay in this option = $219.24 + $193.7 = $412.94

Of all the three options, the option that minimizes their expenses is when Stephanie insures herself and Jim with her employers for a total cost of $408.2 compared to a total cost of $471.09 if Jim insures the two of them with his employers or $412.94 if they respectively insure each other with their respective employers.

Insurance is termed as the process of safeguarding against financial loss. It's a type of risk management that's used mostly to protect against the danger of a speculative or unpredictable loss.

An insurer, an insurance company, an insurance carrier, an underwriter is a business that sells insurance.

The correct answer is option B.  Stephanie should add Jim to her health care plan.

The evaluation of each and every option is as follows:

Option 1

If Jim and his wife are covered by Jim's employer's insurance.

Jim's $378 monthly premium is covered by his company to the tune of 42 percent. Additional beneficiaries will be covered by 23 percent of his insurance plan's $345 cost.

Jim will have to pay 0.58 of $378 for himself and 0.73 of $345 for his wife.

Jim's payment = = $471.09

Option 2

If both of them are protected by Stephanie's company's insurance.

Stephanie's company pays 35% of her $298 monthly premium, but she has the choice of paying a further 10% of her discount for each beneficiary she adds to her plan. For each new beneficiary, her employer would pay 30% of the $349 payment.

Stephanie would pay (0.65 of $298) for herself plus (0.70 of $349) for her husband, minus (10 percent of $298) that her firm wants to pay out of any of her extra recipients' insurance payments.

Stephanie will pay $408.2 by multiplying (0.65 298) by (0.70 349) by (0.10 298).

Option 3

If they both join an insurance plan via their companies, Jim's employer will cover 42 percent of his $378 monthly payment.

Stephanie's $298 monthly charge is compensated by the business to the tune of 35%.

For himself, Jim would pay [tex](0.58 \times \$378)[/tex]= $219.24

Stephanie would pay (0.65 $298) for herself = $193.7 The total cost of this option would be $219.24 + $193.7 = $412.94.

Stephanie ensures herself and Jim with her employers for a total cost of $408.2, against a total cost of $471.09 if Jim insures the two of them with his employers or $412.94 if they insure each other with their respective jobs.

Step-by-step explanation:

There are several transformations for a function f(x). Some of them are shown below:

1. If [tex]f(x)+k[/tex], then the function is translated "k" units up.

2. If [tex]f(x)-k[/tex], then the function is translated "k" units down.

3. If [tex]f(x+k)[/tex], then the function is translated "k" units left.

4. If [tex]f(x-k)[/tex], then the function is translated "k" units right.

In this case you have the following function:

[tex]h(x)=log_6x[/tex]

And the function m(x) is obtained by transformating the function h(x). This function is:

[tex]m(x)=log_6(x+3)[/tex]

Then, based on the transformatios shown before, you can identify that:

[tex]m(x)=h(x+3)[/tex]

Therefore, you can determine that you could graph the function  [tex]m(x)=log_6(x+3)[/tex] by translating each point of the graph of the function h(x) 3 units left.

Answer: z = 280

Step-by-step explanation:

If two variables are directly proportional, it means that an increase in the value of one variable causes an increase in the value of the other variable. Also, a decrease in the value of one variable causes an decrease in the value of the other variable.

The variable z is directly proportional to x. If we introduce a constant of variation, the expression would be

z = kx

When x is 10, z has the value 140. It means that

140 = 10k

k = 140/10

k = 14

The equation becomes

z = 14x

the value of z when x = 20 is

Therefore the shortest man of 65.6 cm was more extreme.

Step-by-step explanation:

A z-test is a statistic test. It is used to determine whether two population mean are different when the variances of the population are known and the sample size large.

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

z= the standarized z score

x = the height of sample

μ = mean  = 172.27 cm

σ = standard deviation = 8.82 cm

For tallest

x = 259

[tex]z= \frac{259-172.27}{8.82}[/tex]

  ≈9.83

For shortest

x= 65.6

[tex]z= \frac{65.6-172.27}{8.82}[/tex]

  ≈ - 12.09

The most extreme value has a z score that the furthest from 0.

Since -12.09 is further from 0 than 9.83.

Therefore the shortest man of 65.6 cm was more extreme.
