Answer:

D. Marital status of college students at a university.

Step-by-step explanation:

The mean, as a measure, is appropriate when we are dealing with quantitative measures, that is, the measure that we are dealing with is a number.

In this question:

Options A(age), B(number of pages) and C(income) are all quantitative, so the mean is appropriate.

In Option D, the marital status is a qualitative measure(married, dating, single), so the mean is innapropriate, and this is the answer,

The required simplified value of the given expression is ln[3x³]. Option A is correct.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given expression,
= 4 lnx + ln 3 - ln x
= ln x⁴ + ln [3 / x]   [since ln a - ln b = ln [a / b]]
= ln [3x⁴/x]     [since lna + ln b = ln ab]
= ln[3x³]

Thus, the required simplified value of the given expression is ln[3x³]. Option A is correct.

Answer:

[tex]CSA = 660cm^2[/tex] --- Curved Surface Area

[tex]TSA = 968cm^2[/tex]  --- Total Surface Area

Step-by-step explanation:

Given

Shape: Cylinder

[tex]h = 15[/tex] -- height

[tex]r = 7[/tex] --- radius

Solving (a): The curved surface area (CSA)

This is calculated as:

[tex]CSA = 2\pi rh[/tex]

This gives:

[tex]CSA = 2 * \frac{22}{7} * 7 * 15[/tex]

[tex]CSA = 2 * 22* 15[/tex]

[tex]CSA = 660cm^2[/tex]

Solving (b): The total surface area (TSA)

This is calculated as:

[tex]TSA = 2\pi r(h + r)[/tex]

This gives:

[tex]TSA = 2 * \frac{22}{7} * 7 * (15 + 7)[/tex]

[tex]TSA = 2 * 22 * (15 + 7)[/tex]

[tex]TSA = 2 * 22 * 22[/tex]

[tex]TSA = 968cm^2[/tex]

Answer:

c=36p+36

Step-by-step explanation:

Okay so the cost of the meal without tip is $36. To find the tip, we would multiply p by 36. To find our total (c), we would add this (36p) to the original 36.

In other words:

c=36p+36

(can also be written as c=36(1+p) )

Answer:

Step-by-step explanation:

Use a distributive property.

Isolate the term of y from one side of the equation.

[tex]\Longrightarrow: \sf{A(B+C)=AB+AC}[/tex]

⇒: 4(y+2)=32

First, divide by 4 from both sides.

[tex]\Longrightarrow:\sf{\dfrac{4(y+2)}{4}=\dfrac{32}{4} }[/tex]

Solve.

⇒ 32/4=8

⇒ y+2=8

Subtract by 2 from both sides.

[tex]\Longrightarrow \sf{y+2-2=8-2}[/tex]

Solve.

Subtract the numbers from left to right.

8-2=6

y=6

Answer:

The value of y  = 30 when x = 5

Step-by-step explanation:

We know that when 'y' varies directly proportional to 'x', we get the equation

y ∝ x

y = kx

k = y/x

where k is called the 'constant of direct variation'.

We are given

y = 12 when x = 2

so substituting y = 12 and x = 2 in the equation

k = y/x

k = 12/2

k = 6

Thus, the value of k = 6

We have to determine the value of y when x = 5

so substitute x = 5 and k = 6 in the equation

y = kx

y = 6(5)

y = 30

Therefore, the value of y  = 30 when x = 5

Step-by-step explanation:

1/2

The next four multiples of 1/4 are:

1/2, 3/4, 1, 5/4

A number series is a sequence of numbers that follow a specific pattern or rule. The pattern can be based on a mathematical formula or a logical rule, such as adding or subtracting a fixed amount, multiplying or dividing by a constant, or using a combination of operations.

To find the multiples of 1/4, we can multiply it by whole numbers:

1/4 x 1 = 1/4

1/4 x 2 = 2/4 = 1/2

1/4 x 3 = 3/4

1/4 x 4 = 4/4 = 1 (which is equivalent to 4/4)

Therefore, the next four multiples of 1/4 are:

1/2, 3/4, 1, 5/4.

PZ = 15

Step-by-step explanation:

Similar Triangles

Two triangles are similar if all of their corresponding side lengths are proportional to the same scale factor.

It's given triangles TPR and XPZ are similar, thus we can find the scale factor by comparing two corresponding sides with known lengths.

Sides TR and ZX are corresponding and the proportion of their side lengths is 15/9. The same proportion must be satisfied by the sides TP and XP:

[tex]\displaystyle \frac{15}{9}=\frac{25}{PX}[/tex]

PX and PZ are congruent, thus:

[tex]\displaystyle \frac{15}{9}=\frac{25}{PZ}[/tex]

[tex]\displaystyle PZ=25*\frac{9}{15}[/tex]

Calculating:

PZ = 15

After 10 weeks, Tara will have taken 50 quizzes.

Step-by-step explanation:

Given that Tara took a total of 45 quizzes during the 9-week course, to determine the number of quizzes she will take after 10 weeks, taking into account that it is a proportional relationship, the following calculation must be performed:

(45/9) x 10 = X

5 x 10 = X

50 = X

So, after 10 weeks, Tara will have taken 50 quizzes.
