Answer:

The function is [tex]d=10t[/tex]

domain is 0 to 0.2 hour.

range is 0 to 2 miles.

Step-by-step explanation:

Given that,

Average velocity = 10 miles/hour

Time = 12 min = 0.2 hour

We need to write a function that models the student's distance from home

Using formula of distance

[tex]d=v\times t[/tex]

Where, v = velocity

t = time

d = distance

Put the value into the formula

[tex]d=10t[/tex]

This is a function.

We know that,

Domain :

Domain shows the time.

So, domain = 0 to 0.2 hour

Range :

Range shows the distance.

The range at t =0,

Put the value of t in the function

[tex]d = 10\times0=0[/tex]

The range at t =0.2 hour

[tex]d = 10\times0=0[/tex]

[tex]d=2\ miles[/tex]

So. range = 0 to 2 miles

Hence, The function is [tex]d=10t[/tex]

domain is 0 to 0.2 hour

range is 0 to 2 miles

Answer:

B. Dependent samples

Step-by-step explanation:

Dependent samples occur when you have two samples that do affect one another. Dependent samples are paired measurements for one set of items.

While independent samples occur when you have two samples that do not affect one another.

Independent samples are measurements made on two different sets of items.

Answer:

0.68

Step-by-step explanation:

The formula for z test is given above as:

z = p' - p/√(pq/n)

p' = sample proportion

= Number of infested samples(trees)/ Number of samples

p' = 127/1000 = 0.127

p = 12% = 0.12

q= 1 - 0.12 = 0.88

n = number of samples = 1000

z = 0.127 - 0.12/√(0.88 × 0.12/1000)

z = 0.007/√0.0001056

z = 0.007 /0.0102761861

z = 0.6811865737

Therefore, the z test statistic is approximately ≈ 0.68

Answer:

[tex]\displaystyle V_\text{right} \approx 1696\text{ units}^3[/tex]

Step-by-step explanation:

Recall that the volume for an oblique cylinder is the same for the volume of a right cylinder. That is:

[tex]\displaystyle V_\text{right} = V_\text{oblique} = \pi r^2h[/tex]

Hence, find the volume of the oblique cylinder:

[tex]\displaystyle \begin{aligned} V_\text{oblique} & = (3.14)(6)^2(15) \\ \\ & = 1695.6 \text{ units}^3 \\ \\ &\approx 1696\text{ units}^3\end{aligned}[/tex]

Therefore:

[tex]\displaystyle V_\text{right} \approx 1696\text{ units}^3[/tex]

In conclusion, the volume of the right cylinder is about 1696 units³.

Answer:

24, 72, and 84

Step-by-step explanation:

Let the first, second, and third angles be A, B, and C, respectively.

So, first of all, since the figure is a triangle, the three angles must total 180. Thus:

[tex]A+B+C=180[/tex]

Now, we are told that the measure of one angle (let's use A) is 3 times the measure of a second angle (B). So:

[tex]A=3B[/tex]

And the measure of the third angle (C) is 12 less than the sum of the other two (A&B). Therefore:

[tex]C=(A+B)-12[/tex]

For this equation substitute A for 3B:

[tex]C=(3B+B)-12[/tex]

Combine like terms:

[tex]C=4B-12[/tex]

So we have the following equations thus far:

[tex]A+B+C=180[/tex]

[tex]A=3B[/tex]

[tex]C=4B-12[/tex]

So, substitute A and C in for the first equation:

[tex]A+B+C=180\\(3B)+B+(4B-12)=180[/tex]

Combine like terms:

[tex]8B-12=180[/tex]

Add 12 to both sides:

[tex]8B=192[/tex]

Divide by 8:

[tex]B=24[/tex]

So, the second angle B is 24 degrees.

The first angle A is three times B. Thus, A is 3(24)=72 degrees.

And C is 12 less than the sum of them. Thus:

[tex]C=(72+24)-12\\C=96-12\\C=84[/tex]

So, our angles are:

24, 72, and 84

And we are done :)

Answer:

-1/16 1/32 -1/64

Step-by-step explanation:

They are dividing by -2 each time; therefore, they multiply (1/4) x (-1/2), (-1/16) x (-1/2), (1/32) x (-1/2) because of the keep change flip rule.

Answer:

-

[tex] - \frac{1}{16} \\ \frac{1}{32} \\ \frac{ - 1}{64} [/tex]

Step-by-step explanation:

It's a geometric sequence with the common ratio r = -1/2

1st: -1

2nd: (-1)x(-1/2) = 1/2

3rd: (1/2) x (-1/2) = -1/4

4th: (-1/4) x (-1/2) = 1/8

so:

5th: (1/8) x (-1/2) = -1/16

6th: (-1/16) x (-1/2) = 1/32

7th: (1/32) x (-1/2) = -1/64

Explanation:

All statistical questions involve collecting numerical data (usually from a group of people) and then analyzing it to draw conclusions about the opinions of people of a certain phenomenon as the data varies depending on the response of each person. This process is not required to determine the area of the floor because this has a unique answer and can simply be found by measuring the height and width of the classroom and then multiplying both numbers. Also, this does not imply gathering a lot of data and the data does not vary.

The domain of the function f(x) = 6.5x will be a positive real number.

The domain means all the possible values of x and the range means all the possible values of y.

The distance that a jogger travels at a constant speed of 6.5 miles per hour can be modeled by the linear function f(x) = 6.5x, where x is the time in hours the jogger runs.

We know that time is a scalar quantity. Then the value of the time is always greater than equal to zero.

x ≥ 0

The domain of the function f(x) = 6.5x will be a positive real number.

Answer:

Part A: The unit that would be best to describes the situations is to the mile

Part B: 4 significant figures

Part C: 1,450 miles

Part D: He is not correct

Step-by-step explanation:

Part A: By unit conversion, we have;

1 mile = 1,760 yards

Given that the distance from Ottawa, Canada to Jackson Mississippi is 2,552,000 yards it would best simplified into miles

Part B: The number of significant digits in the reporters estimate are the non-zero digits before the zeros in the number figure which are 2, 5, 5, and 2 or 4 significant figures

Part C: 2,552,000 yards = 2,552,000 yards/(1,760 yards/mile) = 1,450 miles

Part D: Given that the distance from Jackson to Tucson = 7,159,680 feet, we have;

1 mile = 5,280 feet

Therefore;

7,159,680 feet = 7,159,680 feet/(5,280 feet/mile) = 1,356 miles

Therefore, the claim that the distance from Jackson to Tucson which is 1,356 miles is further than the distance from Ottawa, Canada to Jackson Mississippi which is 1,450 miles is not correct because;

[tex]Relative\ Frequency = 0.04[/tex]

Step-by-step explanation:

Given

Cost of Textbooks ---- Frequency

$25 up to $35  -----      2

$35 up to $45 -------     5

$45 up to $55  -------    7

$55 up to $65   ------    20

$65 up to $75   ----   -- 16

Required

Determine the relative class frequency for the $25 up to $35 class

First, we need to get the total frequency

[tex]Total = 2 + 5 + 7 + 20 + 16[/tex]

[tex]Total = 50[/tex]

Next, is to write out the frequency of $25 up to $35 class

[tex]Frequency = 2[/tex]

Divide this frequency by the total frequency; This gives the relative frequency

[tex]Relative\ Frequency = \frac{Frequency}{Total}[/tex]

[tex]Relative\ Frequency = \frac{2}{50}[/tex]

[tex]Relative\ Frequency = 0.04[/tex]
