Answer:

$\huge\boxed{\bf\: 4 (x + 3) \: and \: 4x + 12 }$

Step-by-step explanation:

Let the variable be 'x'.

Sum of 3 and x = x + 3
4 times the sum of 3 and x = 4 (x + 3)

Expression : 4 (x + 3)

On expanding ,

4 (x + 3)

= (4*x) + (4*3)

= 4x + 12 ⟶ equivalent expression to the statement .

When using a one-tailed test and a sample size of 24, what is the probability of a value being to the left of a number that has

UNO [17]

Answer:

P-value = 0.009997

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 24

Nature of test: One-tailed test(Left tailed test)

$t_{\text{statistic}} = -2.50$

We have to calculate the p-value.

Degree of freedom = n - 1 = 23

We calculate the p-value from the table corresponding to t score -2.50 and degree of freedom 23.

P-value = 0.009997

0.009997 is the probability of a value being to the left of a number that has a student-t statistic of –2.50.

Suppose you can work a total of no more than 38 hours each week at your two jobs. Housecleaning pays $7 per hour and your retail

MA_775_DIABLO [31]

Answer:

The system of inequalities is:

7x + 8y ≥ 280

x + y ≤ 38

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Amount of weekly hours you can work, no more than 38 hours (≤ 38)

Rate at housecleaning per hour = US$ 7

Rate at retail job per hour = US$ 8

Salary per week, at least US$ 280 (≥ 280)

2. Complete the system of linear inequalities to model this situation.

x = Number of hours per week worked at housecleaning job

y = Number of hours per week worked at retail job

Now, we have:

7x + 8y ≥ 280 (Total of salary of the two jobs should be at least US$ 280), where 7x is the salary received from housecleaning job and 8y is the salary received from retail job

x + y ≤ 38 (You can't work more than 38 hours per week)
