We can use two data points to find the linear function that relates the two quantities. For example, a linear function relating calories (C) consumed over days(d) can be generated from the following data: -After 3 days 4,100 calories have been consumed. -After 8 days 10,600 calories have been consumed. The slope of this function is________ and indicates the number of calories consumed each day. The y-intercept of this function is_________ and indicates the calories consumed at day . This function can be modeled by C=______

24-4 =20

The sister is 20

Answer: 20 years old

Step-by-step explanation: So, we know the girl is 4 years older than the sister...how do we know that? Because...

6 - 2 = 4

She's 4 years older...we know the girl is 24, then the sister must be 20.

Answer:

A on e2020

Step-by-step explanation:

The solution is, The length of line segment AB is 3.4cm.

Line segment is the part of line which have two endpoint and bounded by two distinct end points and it contain every point on the line which is between its endpoint.

here, we have,

The area of octagon is given as 2a^2(1+sqrt{2})

Where a is the side of octagaon.

All sides of octagon are same.

now, we get,

As, 2a^2(1+sqrt{2}) = 54cm

so, we have,

Then, a^2 = 54/2(1+sqrt{2})

a^2 = 54/4.828

a^2 = 11.19

a = 3.4 cm

Hence, The solution is, The length of line segment AB is 3.4cm.

Answer:

   4)  c = 38

   5)  x = 50

Step-by-step explanation:

4) The marked angles are a "linear pair", meaning their total is 180°:

  3c° +(2c -10)° = 180°

  5c = 190 . . . . . . . divide by °, add 10, collect terms

  c = 38 . . . . . . . . . divide by 5

__

5) The interior angle at C brings the total of the marked angle and the interior angle to 360°

  330° + (interior angle) = 360°

  (interior angle) = 30° . . . . . . . . . subtract 330°

The interior angles of the triangle total 180°, so we have ...

  x° +2x° +30° = 180°

  3x = 150 . . . . . . . . . . . . . divide by °, subtract 30

  x = 50 . . . . . . . . . divide by 3

2 is your answer

Step-by-step explanation:

Answer:

55

Step-by-step explanation:

All triangles have a sum of 180°

180 - 40 = 140

Since the triangle is an isosceles triangle, then you are going to divide 140 by 2 because the base angles of an isosceles triangle are congruent.

140 / 2 = 70

Now that we know that the measurement of the two base angles is 70, we can find h.

2h represents the exterior angles. Exterior angles are always supplementary to the interior angles. So, we can simply subtract 70 from 180.

180 - 70 = 110

Now, we can divide 110 by 2 to find h.

110 / 2 = 55

So, h equals 55. So, the answer is the third option.

Given: 5 quiz scores of a student in a statistics course are 6,6, 5, 8, 10

To find:  standard deviation of the population

Solution:

Mean (M) = [tex]\frac{\sum_{i=1}^{n}x_i}{n}[/tex]

here, [tex]x_i[/tex] denotes number of observations and n denotes number of observations.

Variance = [tex]\frac{\sum_{i=1}^{n}(x_i-M)^2}{n-1}[/tex]

Standard deviation = [tex]\sqrt{variance}[/tex]

[tex]M=\frac{6+6+5+8+10}{5}=\frac{35}{5}=7[/tex]

Variance = [tex]\frac{\sum_{i=1}^{n}(x_i-7)^2}{n-1}[/tex]

[tex]=\frac{\left [ (6-7)^2+(6-7)^2+(5-7)^2+(8-7)^2+(10-7)^2 \right ]}{5-1}\\=\frac{1+1+4+1+9}{4}\\=\frac{16}{4}\\=4[/tex]

Step-by-step explanation:

If T:Rn→Rm is a linear transformation and if A is the standard matrix of T, then the following are equivalent:

 1.  T is one-to-one.

 2. T(x) = 0 has only the trivial solution x=0.

 3.  If A is the standard matrix of T, then the columns of A are linearly independent.

Here, A is a mxn matrix where m ≥ n and the rank of A equals n. It implies that the columns of A are linearly independent, for, otherwise, the rank of A would be less than n. Hence the linear transformation represented by A is one-to-one.

Recall the Pythagorean identity,

[tex]\sec^2\theta=1+\tan^2\theta[/tex]

So we have

[tex]\sec^2\theta=4+2\tan^2\theta[/tex]

[tex]1+\tan^2\theta=4+2\tan^2\theta[/tex]

[tex]-3=\tan^2\theta[/tex]

But squaring any real number always gives a non-negative number, so there are no real solutions to this equation.

Answer: 6

Explanation: The mean of a data set is the sum of the numbers in the data set divided by however many numbers are in the data set.

So, let's begin by adding the numbers.

So we have 3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 which is 48.

Now we divide 48 by the number of numbers in the set which is 8.

48 ÷ 8 is 6.

So the mean of the given data set is 6.

Answer:

And we can find the distance between JK like this:

[tex] d_{JK} =\sqrt{(3-3)^2 +(2+1)^2}= 3[/tex]

And we can do something similar for KL and we got:

[tex] d_{KL} =\sqrt{(-5-3)^2 +(2-2)^2}= 8[/tex]

And we can do something similar for LM and we got:

[tex] d_{LM} =\sqrt{(-5+5)^2 +(-1-2)^2}= 3[/tex]

And we can do something similar for MJ and we got:

[tex] d_{MJ} =\sqrt{(-5-3)^2 +(-1+1)^2}= 8[/tex]

And the perimeter would be:

[tex] P = d_{JK} + d_{KL} +d_{LM} +d_{MJ} = 3+8+3+8 =22[/tex]

Step-by-step explanation:

For this case we can use the formula for the euclidean distance given by:

[tex] d = \sqrt{(y_2 -y_1)^2 +(x_2 -x_1)^2}[/tex]

And we can find the distance between JK like this:

[tex] d_{JK} =\sqrt{(3-3)^2 +(2+1)^2}= 3[/tex]

And we can do something similar for KL and we got:

[tex] d_{KL} =\sqrt{(-5-3)^2 +(2-2)^2}= 8[/tex]

And we can do something similar for LM and we got:

[tex] d_{LM} =\sqrt{(-5+5)^2 +(-1-2)^2}= 3[/tex]

And we can do something similar for MJ and we got:

[tex] d_{MJ} =\sqrt{(-5-3)^2 +(-1+1)^2}= 8[/tex]

And the perimeter would be:

[tex] P = d_{JK} + d_{KL} +d_{LM} +d_{MJ} = 3+8+3+8 =22[/tex]

The perimeter of the rectangle with the given vertices is: 22 units.

Recall:

Thus, find the length (JK) and width (KL) of the rectangle.

Width of rectangle = distance between J(-1,3) and K(2,3):

[tex]JK = \sqrt{(3 - 3)^2 + (2 - (-1))^2} \\\\JK = \sqrt{(0)^2 + (3)^2} \\\\JK = \sqrt{9} \\\\JK = 3[/tex]

Length of rectangle = distance between K(2,3) and L(2,-5)

[tex]KL = \sqrt{(-5 - 3)^2 + (2 - 2)^2} \\\\KL = \sqrt{(-8)^2 + (0)^2} \\\\KL = \sqrt{64} \\\\KL = 8[/tex]

Perimeter of the rectangle = 2(length x width)

Perimeter of the rectangle = 2(8 + 3)

Perimeter = 2(11)

Perimeter = 22 units
