You ask learners to select their course section number for your survey. For example, (1) 101, (2) 102, (3) 103. What type of variable is course section in this example?

Answers

Answer:

The variable is a nominal categorical variable

Step-by-step explanation:

As the 3 options are available and the survey taker is required to select from these options, this indicates that the variable is of categorical nature, where only a fixed number of options are available. As the order is not important thus the variable is a nominal categorical variable.

Give me a hand please! Triangle VZX is similar to RPQ where ZX corresponds to PQ. If VZ = 8 cm, ZX = 6.4 cm, VX = 11.2 cm, and PQ = 5.12 cm, what is the measure of RQ?

A) 4.096 cm
B) 10 cm
C) 8.96 cm
D) 6.4 cm

Answers

Answer:

C: 8.96

Step-by-step explanation:

We know taht ZX is similar to PQ. We can now set up the ratio of 6.4: 5.12

This ratio gives us .8:1

Multiply VX by the ratio to find its corresponding similar side of RQ

(11.2) * .8 = 8.96

Answers

Answer:

y = 3

Step-by-step explanation:

Here, we want to get the horizontal asymptote

To get this, we have to equate the denominator to 0 and solve for x

Mathematically, we have this as;

x-3 = 0

x = 3

so the horizontal asymptote will be y = 3

Use the net to find the surface area of the regular pyramid.

Answers

Answer:

40 in²

Step-by-step explanation:

There are four triangles for each side of the pyramid, and the height is three inches. The area of a triangle is base times height divided by 2, so each triangle is 6 in².

4(base) x 3(height) ÷ 2 = 6

Multiply 6 by 4 because there are four triangles, which is 24.

Once you have that, the only surface left is the bottom of the pyramid. You can find this by multiplying 4 by 4, since it's a square.

4 x 4 = 16

If you add 16 and 24 together, that's your answer.

The American Water Works Association reports that the per capita water use in a single-family home is 76 gallons per day. Legacy Ranch is a relatively new housing development. The builders installed more efficient water fixtures, such as low-flush toilets, and subsequently conducted a survey of the residences. Twenty-seven owners responded, and the sample mean water use per day was 71 gallons with a standard deviation of 9.5 gallons per day. At the 0.01 level of significance, is that enough evidence to conclude that residents of Legacy Ranch use less water on average

Answers

Answer:

Yes, that is enough statistical evidence to suggest to conclude that residents of Legacy Ranch use less water on average

Step-by-step explanation:

The data given by the American Water Works Association are;

The per capita water use in a single-family home, μ = 76 gallons per day

The number of responders in the sample, n = 27

The sample mean water used by the sample, [tex]\overline x[/tex] = 71 gallons

The standard deviation, s = 9.5 gallons per day

The level of significance, α = 0.01

The test statistics is given as follows;

The null hypothesis, H₀; μ ≥ 76 gallons

The alternative hypothesis, Hₐ; μ < 76 gallons

[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]

Therefore, we have;

[tex]t=\dfrac{71-76 }{\dfrac{9.5}{\sqrt{27}}} \approx -2.734817[/tex]

At n - 1 = 27 - 1 = 26 degrees of freedom, the critical-t = 2.5

From the test statistic, of t ≈ -2.734817, the p-value < 0.01, and from a graphing calculator, the p-value is given as Prob = 0.005544418

Therefore, given that the p-value is less the significant level, and less than 0.01, is therefore statistically significant, and therefore, there is sufficient statistical evidence against the null hypothesis, therefore we reject the null hypothesis, and there is enough statistical evidence to suggest to conclude that residents of Legacy Ranch use less water on average.

Step-by-step explanation:

Given that

Skylar has a collection of 60 comic books

She gave away some of her books

And she left by 48 books

we need to find out the percent of the skylar give away books

= (60 - 48) ÷ 60

= 12 books ÷ 60 books

= 20%

Hence, the percent of her comic books did Skylar give away is 20%

If these cubes are to to be placed so that their respective faces are parallel

or perpendicular, as the case may be, to the respective orientations of the

dimensions of the box, without tilting any cubes in any directions,

then choice B) can be justified. This leaves spaces (some volume) in the box

not filled by the cubes.

How many whole number of edges of the cubes fit into 4 cm?  

4 / 3 √ 2   must be rounded down to 3.

How many whole number of edges of the cubes fit into 8 cm?  

8 / 3 √ 2   must be rounded down to 6.

How many whole number of edges of the cubes fit into 10 cm?  

10 / 3 √ 2   must be rounded down to 7.

Then (3)(6)(7) = 126

You are given m =0.4n - 2/3
What is the value of m, when n is 15?
A.0 3.7
B.4.3
C.6.0
D.8.3

Answers

Answer:

m = 5.3

Step-by-step explanation:

Given equation,

→ m = 0.4n - (2/3)

Now we have to,

→ Find the required value of m.

We have to use,

→ n = 15

Then the value of m will be,

→ m = 0.4n - (2/3)

→ m = 0.4(15) - (2/3)

→ m = 6 - (2/3)

→ m = (18/3) - (2/3)

→ m = (18 - 2)/3

→ m = 16/3

→ [ m = 5.3 ]

Hence, the value of m is 5.3.
