Answer:

D. The samples are independent because there is not a natural pairing between the two samples

explanation:

Independent samples do not affect each other as each group is selected randomly. They are common in statistical analysis, example: when there is a control group and an experimental group and the subjects for each group are different. In the above example, the samples do not depend on each other. There are 90 randomly selected married men in one group and 90 randomly selected married women in the other. The subjects are different in the two groups and so they do not affect each other. This is unlike dependent/paired samples where for example same subjects are used before and after a medication and therefore each group affects the other.

The integer -40 represents the balance that he owes his father if Roger owes his father $15. He borrows another $25 from him.

it is defined as the whole number it can be a negative whole number or a positive whole number for example 2, 4, 1, -8, 0, etc.

It is given that:

Roger owes his father $15. He borrows another $25 from him.

As we know, the number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

The amount Roger owes = $15

Roger borrows = $25

Total debt = -15 + (-25)

Total debt = -$40

The above integer represents the balance that he owes his father.

Thus, the integer -40 represents the balance that he owes his father if Roger owes his father $15. He borrows another $25 from him.

Solution: (-4,5)

Step-by-step explanation:

x=16-4y

3x+4y=8

-----

The 1st equation tells you x = 16-4y

---

Substitute that into the 2nd equation

and solve for "y":

3(16-4y)+4y = 8

48 - 12y + 4y = 8

-8y = -40

---

y = 5

---

Solve for "x"

x = 16-4y

x = 16-4*5

x = 16-20

x = -4

The given system of equations has (-4, 5) as its solution.

We have the following system of equations -

x = 16 - 4y

3x + 4y = 8

Now, we can write -

3x + 4y = 8

3(16 - 4y) + 4y = 8

48 - 12y + 4y = 8

40 = 8y

y = 5

Then, we can write -

x = 16 - 20

x = - 4

Therefore, the given system of equations has (-4, 5) as its solution.

#SPJ2

Answer:

About 18% increase

Step-by-step explanation:

x = number of appointments

y = total amount earned in dollars

The total earnings equation is y = 2x+40

The 2x is from her earning $2 per appointment. If she makes x of them, then she earns 2x dollars. This is on top of the $40 from working the full day.

She wants to earn at least $75. This means she wants to earn $75 or more.

This means,

[tex]y \ge 75\\\\2x+40 \ge 75\\\\2x \ge 75-40\\\\2x \ge 35\\\\x \ge \frac{35}{2}\\\\x \ge 17.5[/tex]

Since x is the number of appointments, and we can't have a fractional number of appointments, we must round up to x = 18. This is the lowest number of appointments she can do and earn $75 or larger.

If x = 17, then

y = 2x+40 = 2*17+40 = 34+40 = 74

which is not 75 or larger

But if x = 18, then

y = 2x+40 = 2*18+40 = 36+40 = 76

which is larger than 75, so we've cleared the hurdle.

We can say the solution set is [tex]x \ge 18[/tex] where x is a whole number. So she could book x = 18, x = 19, x = 20, x = 21, etc as the number of appointments to reach her goal.

In summary, she must schedule at least 18 appointments to earn $75 or more.

Since she makes $2 for every appointment she makes we would need to use 40+2n so she would get $2 per appointment no matter how many appointments she makes. Also, we wouldn't use an equal sign because they didn't say she needed to earn exactly $75. They said she needed to earn "at least" $75. At least means equal to or greater than ≥. So the inequality would be 2n+40≥75. PRO TIP: Any time it asks you to write an inequality you will use either <, >, ≤, or ≥ not an =.An equation uses =, an inequality uses the other symbols

Answer:

Jacob can have up to 5 guests at his graduation party because 50 - 22.50 is 27.50 and 27.50/5.50 is 5.

Step-by-step explanation:

To start off you would subtract 22.50 from 50 leaving you with 27.50. From there you would account for the number of attendees. Since 27.50/5.50 equals 5 the maximum amount of guests Jacob can have at his graduation party is 5.

Step-by-step explanation:

Answer:

The answer will be

Given:

Initial value of new car = $17,500

Depreciation rate = 4.6%

To find:

The value of car after 4 years.

Solution:

The exponential decay model is

[tex]y=a(1-r)^t[/tex]

where, a is initial value, r is decreasing rate and t is time in years.

Substitute a=17500, r=0.046 and t=4 in the above equation.

[tex]y=17500(1-0.046)^4[/tex]

[tex]y=17500(0.954)^4[/tex]

[tex]y=17500(0.8283111)[/tex]

[tex]y=14495.44425[/tex]

[tex]y\approx 14495.44[/tex]

The value of car after 4 years is $14495.44.

Therefore, the correct option is D.

Answer:

C. g(x) = x²+4

Step-by-step explanation:

Given the parabola function f(x) = x²

Translating the function up by 4 means adding the constant value of +4 to the function since it's translated along the positive y axis. The resulting function g(x) will be x²+4

Hence the correct answer is g(x) = x²+4. Option C is correct.
