Answer:

[tex][-5,5][/tex]

Step-by-step explanation:

The range is the y-axis, and the endpoints are filled in, so we put brackets.

Side note:

This is called Interval Notation. This is very important when you ask for the domain and range of functions (domain is for the x-axis). You will see this system A LOT, so you have to get used to the name and the language Interval notation uses.

Step-by-step explanation:

11/2, -11, 22, -44, 88, -176

common ratio : 22/(-11) = -2

Answer:

12 < x < 42 or x | ( 12,42 ) ft.

Step-by-step explanation:

15 + 27 = 42; 27 − 15 = 12 . Therefore the third side must be

less than 42 ft ant greater that 12 ft. Therefore possible length

of third side of size x is 12 < x < 42 or x | ( 12,42 ) ft [Ans]

Step-by-step explanation:

1 hours = 60

1 m = 60 sec

so 2 × 60 × 60 = 7200 sec

1 km = 1000m

8 km= 8000m

Answer:

2 hours into seconds is 7200 seconds.

8 kilometers into meters is 8000 meters.

Step-by-step explanation:

To convert hours into seconds, multiply the number of hours by 3600.

To convert kilometers into meters, multiply the number of kilometers by 1000.

Step-by-step explanation:

Answer: Lines [tex]\frac{}{BC}[/tex] and [tex]\frac{}{EF}[/tex] are different lengths.

Step-by-step explanation:

The distance formula is [tex]\sqrt{(x_1-x_2) ^{2}+(y_1-y_2) ^{2} }[/tex], and you can use this formula to solve for the lengths of both lines [tex]\frac{}{BC}[/tex] and [tex]\frac{}{EF}[/tex].

For line [tex]\frac{}{BC}[/tex], let [tex]x_{1}[/tex] = the x at point B, or 1, and let [tex]x_{2}[/tex] = the x at point C, or 2.

Now, let [tex]y_{1}[/tex] = the y at point B, or 4, and let [tex]y_{2}[/tex] = the y at point C, or -1.

Now, solve the formula to find the length [tex]\frac{}{BC}[/tex] = [tex]\sqrt{(x_1-x_2) ^{2}+(y_1-y_2) ^{2} }\\[/tex].

[tex]\frac{}{BC}[/tex] = [tex]\sqrt{(1-2)^{2} +(4-(-1))^2[/tex]

[tex]\frac{}{BC}[/tex] = [tex]\sqrt{(-1)^{2} +(4+1)^2[/tex]

[tex]\frac{}{BC}[/tex] = [tex]\sqrt{1 +5^2[/tex]

[tex]\frac{}{BC}[/tex] = [tex]\sqrt{(1+25)[/tex]

[tex]\frac{}{BC}[/tex] = [tex]\sqrt{26} \\[/tex]

Now, for line [tex]\frac{}{EF}[/tex], let [tex]x_{1}[/tex] = the x at point E, or -4, and let [tex]x_{2}[/tex] = the x at point F, or -1.

Let [tex]y_{1}[/tex] = the y at point E, or -3, and let [tex]y_{2}[/tex] = the y at point F, or 1.

Now, solve the formula to find the length [tex]\frac{}{EF}[/tex] = [tex]\sqrt{(x_1-x_2) ^{2}+(y_1-y_2) ^{2} }\\[/tex].

[tex]\frac{}{EF}[/tex] = [tex]\sqrt{(-4-(-1))^{2} +(-3-1)^2[/tex]

[tex]\frac{}{EF}[/tex] = [tex]\sqrt{(-4+1)^{2} +(-4)^2[/tex]

[tex]\frac{}{EF}[/tex] = [tex]\sqrt{(-3)^2+16[/tex]

[tex]\frac{}{EF}[/tex] = [tex]\sqrt{(9+16)[/tex]

[tex]\frac{}{EF}[/tex] = [tex]\sqrt{25}[/tex]

[tex]\frac{}{EF}[/tex] = 5

Now, look back at [tex]\frac{}{BC}[/tex]. The two lines have different lengths, so you have now justified the fact that they are not the same.

Answer:

When estimating area, count the squares that cover the shape. When estimating perimeter, count the unit lengths that are around the shape

Step-by-step explanation:

Step-by-step explanation:

The slope of g(t) as (-2,2) is given by

[tex]g'(t)=2t+6[/tex]

[tex]g'(-2)=2(-2)+6=2[/tex]

Since the normal is parallel to the tangent of f(t) at (1, 1/2),

The tangent line of f(t) has a slope of

[tex]\dfrac{d}{dx}f(t)=n+2mt=2[/tex]

At point (1, 1/2), we know

[tex]f'(1)=n+2m=2[/tex]

[tex]f(1)=2+n(1)+m(1)^2=2+n+m=\frac12[/tex]

Solving,

[tex]n=5, m=-\frac72[/tex]

9514 1404 393

Answer:

Step-by-step explanation:

The slope of a line in the form ...

  ax +by = c

is ...

  m = -a/b

So, the slope of the given line is ...

  -4/(-3) = 4/3

The slope of the perpendicular line is the opposite reciprocal of this,

  m' = -1/(4/3) = -3/4

__

The point-slope equation of a line is ...

  y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

Then your perpendicular line with slope -3/4 through point (-8, 7) is ...

  y -7 = -3/4(x +8)

Rearranging to slope-intercept form, we get ...

  y = -3/4x -3/4(8) +7

  y = -3/4x +1

Step-by-step explanation:

The first operation is what inside the braces

1-first comes the multiple and the division

2- then the + and the -

1- (25-36)+5(8-4)

2- (25-36) + 5×4

3- (-11) + 20 =9

Answer:

Step-by-step explanation:

There appears to be a problem with your equation as it can be reduced to

y = (a + b)x + 3

which is a line of slope (a + b) and y intercept of 3

plugging in our points

10 = -1(a + b) + 3

7 = -1(a + b)

a + b = -7

13 = 2(a + b) + 3

10 = 2(a + b)

a + b = 5

a + b cannot equal both 5 and -7 at the same time.

I will GUESS that you mean y = ax² + bx + 3

10 = a(-1)² + b(-1) + 3

10 = a - b + 3.

 b = a - 7

13 = a(2)² + b(2) + 3

13 = 4a + 2b + 3

10 = 4a + 2b

10 = 4a + 2(a - 7)

10 = 4a + 2a - 14

24 = 6a

a = 4

b = 4 - 7

b = -3

True, two samples are selected from a population, and a treatment is administered to the samples. If both samples have the same mean and the same variance, you are more likely to find a significant treatment effect with a sample of n = 100 than with a sample of n = 4.

The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.

Given:

Two samples are selected from a population, and a treatment is administered to the samples.

If both samples have the same mean and the same variance.

That means, they have the same t statistic.

A t-test compares the average values of two data sets and determines if they came from the same population.

You are more likely to find a significant treatment effect with a sample of n = 100 than with a sample of n = 4.

Because the value of t-test are same.

Therefore, the statement is true.

The 10 hypothetical numbers which meets the conditions given on the question may include :

1, 2, 3, 5, 6, 6, 7, 10, 10, 12

The five number summary include the maximum, minimum, lower quartile, Median and upper quartile of a distribution.

The five number summary of the hypothetical data are:

Median: 6

Minimum: 1

Maximum: 12

Lower quartile: 2.75

Upper quartile: 10

Comparing the 5 - number summary of the hypothetical data with that of the given boxplot.

From the given  boxplot shown :

Minimum value = 1

Maximum value = 12

Median = 6

LOWER QUARTILE, Q1 = 4

UPPER QUARTILE, Q3 = 8

IQR = (Q3 - Q1) = 8 - 4 = 4

THE 10 made up numbers :

1, 2, 3, 5, 6, 6, 7, 10, 10, 12

The five number summary for the made up data :

Median = 1/2(n+1)th term = 5.5th term = (6+6)/2 = 6

Minimum: 1

Maximum: 12

First quartile = 1/4(n+1)th = 2.75th term = (2+3)/2 = 2.5

Third quartile: 3/4(n+1)th term = 8.25 = (10+10)/2 = 10

Interquartile Range: (10 - 2.5) = 7.5
