Answer: 9.1 credit hours per semester.

Step-by-step explanation:

  • The sample size(\overline{x}) is the best point-estimate for the true population mean(\mu) ( if true population mean is unknown).

Given : At the local college, by taking a sample of 96 students , study found that students earned an average of 9.1 credit hours per semester.

i.e. \overline{x}=9.1 credit hours per semester.

Then, the best point estimate for the average number of credit hours per semester for all students at the local college should be sample mean

i.e. \mu=\overline{x}=9.1 credit hours per semester.

Elenna [48]

Answer:

<h3>           The father is 40 and the daughter is 20.</h3>

Step-by-step explanation:

x           -  the present age of the daughter

2x         -  the present age of the fathter  

x - 10          -  the age of the daughter ten year ago

2x - 10        -  the age of the fathter ten year ago

Father is older than his dauther, so:

2x - 10 = (x - 10) + 20  

2x - 10 = x - 10 + 20  

2x - 10 = x + 10              {subtract x from both sides}

x - 10 = 10                      {add 10 to both sides}

x = 20

2x = 2·20 = 40

Mr. and Mrs. Suralbo earned a net taxable income of P568,986. Find the income tax due.
Contact [7]

Answer:

$198,000

Step-by-step explanation:

Since Mr. and Mrs. Suralbo are married and filing jointly, they would fall into the tax slab of 35% as their taxable income ranges between $414,701 to $622,050.

Taxable income = $568,986

Tax rate = 35%

Income tax due = $568,000 * 35/100

= $198,000

Thus, the income tax due for Mr. and Mrs. Suralbo would be $198,000.

Analyze the graph of the function f(x) to complete the statement.
Burka [1]

The function f(x) is less than 0 at x < -1.8

<h3>How to analyze the graph?</h3>

The missing graph is added as an attachment

The interval where f(x) < 0 are the intervals where the y value of the function is less than 0.

This in other words, represent the negative y-axis

From the attached graph, the function f(x) is less than 0 at x < -1.8.

This extends till x = infinity

Hence, the function f(x) is less than 0 at x < -1.8
