A pair of Political affiliation and residential status can be used as pair of varibles for which the researcher conduct the chi-square test of independence.

We have a researcher survey random sample of 750 college students about their political views.

This survey contains the following variables,

political affiliation (democrat / republican / other) annual income number of hours worked per week residential status (on-campus / off-campus)

A tool box has the dimensions of 10 in by 4 in by 3 in. If Andrea plans to double one dimension to build a larger tool box, she believes she would double the volume of the tool box. Is she correct?

Answers

Answer: Yes

Step-by-step explanation:

Given

Dimension of the toolbox is [tex]10\ in.\times 4\ in.\times 3\ in.[/tex]

suppose the length of the box is doubled, then a new length will be [tex]2\times 10\ in.[/tex]

So, the volume of the box becomes

[tex]\Rightarrow V=2\times 10\times 4\times 3[/tex]

It can also be written as

[tex]\Rightarrow V=2\times (10\times 4\times 3)=2\times (V_{old})[/tex]

i.e. the volume of the toolbox is doubled. Therefore, Andrea is correct.

A clerical worker takes 3 times as long to finish a job as it does an executive secretary. Working​ together, it takes them 4 hr to finish the job. How long would it take the clerical​ worker, working​ alone, to finish the​ job?

Answers

Answer:

8 hours

Step-by-step explanation:

In 2 hours, the clerical secretary can do 1/4 of the job. (The executive secretary does 3/4 of the job - or 3 times as much - in the same 2 hours.)

Since it takes the clerical secretary 2 hours to do 1/4 of the job, it will take them four times that to do it themselves. 2x4=8.

Diana decided she needed some new friends to play with. She understood that fish were not fun to hang out with, so she bought 3 baby mice and 2 baby pythons for a total cost of $103.50. Mr. Reyes also thought this was a great idea. He bought 3 baby mice and 3 baby pythons for a price of $148.50. Find the price of the mouse and the price of the python.

Answers

Step-by-step explanation:

Let m be the price of 1 baby mice

Let p be the price of 1 baby python

Given,

[tex]3m + 2p = 103.50[/tex]

as equation 1.

and

[tex]3m + 3p = 148.50[/tex]

as equation 2

From here we can easily use elimination method

for solving simultaneous equations.

Use Equation 1 - equation 2 to eliminate m to find p.

[tex](3m - 3m) + (2p - 3p) = 103.50 - 148.50 \\ - p = - 45 \\ p = 45[/tex]

Substitute p into equation 1.

[tex]3m + 2(45) = 103.50 \\ 3m + 90 = 103.50 \\ 3m = 103.50 - 90 \\ 3m = 13.50 \\ m = 13.50 \div 3 \\ = 4.50[/tex]

therefore 1 baby mice cost $4.50 and 1 baby python costs $45.

Answer:

Baby python: $45

Baby mouse: $4.5

Step-by-step explanation:

First of all, 3 baby mice and 2 baby pythons cost $103.50. When Mr. Reyes adds a baby python (He bought 3 baby mice and 3 baby pythons for a price of $148.50.) To find the price of a baby snake, you need to subtract both prices. 148.5-103.5=45, so a baby snake costs $45. Now we need to find the price of the baby mice, so we need to remove the snakes. 45*2=90. (2 snakes). 103.5-90=13.5, and 13.5/3=4.5, so a baby mouse costs $4.5.

Solve the variable in the following equation: 5 + h = 11 − 2h
A. h = −1

B. h = 2

C. h = 5

D. h = 9

Answers

Answer: B. h = 2

Step-by-step explanation:

Given

5 + h = 11 - 2h

Add 2h on both sides

5 + h + 2h = 11 - 2h + 2h

5 + 3h = 11

Subtract 5 on both sides

5 + 3h - 5 = 11 - 5

3h = 6

Divide both sides by 3

3h / 3 = 6 / 3

h = 2

Answers

Answer:

b took the test right now

Step-by-step explanation:

The required, seat width is the continuous variable in the given table.

What is continuity?

Continuity is a mathematical concept that describes the smoothness of a function or a curve. A function is said to be continuous if there are no abrupt changes or breaks in the values it takes as the input varies. More formally, a function f(x) is continuous at a point x = a if the limit of f(x) as x approaches a from both sides exists and is equal to f(a).

For example, a function that describes the temperature in a room as a function of time is continuous if there are no sudden changes or jumps in the temperature.

Here,
The number of seats is not a continuous variable because it can only take discrete values (such as 120, 225, etc.).

The Wi-Fi and first-class variables are not continuous either because they are categorical variables that can only take a limited number of values (yes or no).

The seat width variable, however, is a continuous variable because it can take on any value within a range of values (such as between 19.9 inches and 20.6 inches). Therefore, seat width is the continuous variable in the given table.
