Answer:

3

Step-by-step explanation:

The slope of the line passing through the points is

m = (y2-y1)/(x2-x1)

    = ( 1-2)/(8-5)

   = -1/3

The slope that is perpendicular is the negative reciprocal which is

- ( 1/(-1/3)

+ 3/1

The perpendicular slope is 3

Answer:

14

Step-by-step explanation:

8 + 3e

e = 2

substitute in the given value

8 + 3(2)

simplify

8 + 6

14

Answer: 14

Step-by-step explanation: Here, we have the expression 8 + 3e

and we want to evaluate the expression when e = 2.

To evaluate an expression, we simply plug the

value of the variable into the expression, and solve.

So here, since e = 2, we have 8 + 3(2).

3(2) is equal to 6 so we have 8 + 6, which is equal 14.

It’s a good idea to get into the habit of using parentheses

when substituting numbers in for variables.

So the value of our expression when e = 2 is 14.

Answer:

y = 5

Step-by-step explanation:

Step 1: Write equation

-(4y + 2) - (-3y - 6) = -1

Step 2: Solve for y

Step 3: Check

Plug in y to verify it's a solution.

-(4(5) + 2) - (-3(5) - 6) = -1

-(20 + 2) - (-15 - 6) = -1

-22 - (-21) = -1

-22 + 21 = -1

-1 = -1

Answer:

In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints

31

31 is the value of expression 5x + 6 when x is 5.

An expression is combination of variables, numbers and operators.

The given expression is 5x+6

Five times of x plus six

We need to find the value of the given expression when the value of x is five.

x=5

We need to substitute the value of x in the given expression

5(5)+6

Five times of five is twenty five and when added with six we get 31

25+6

31

Hence, 31 is the value of expression 5x + 6 when x is 5.

Answer:

set d. and omg your screen

Step-by-step explanation:

n = - 1

Hi !

6 = - 2(10n + 7)

6 = - 20n - 14

20n = - 6 - 14

20n = - 20

n = - 20 : 20

n = - 1

6 = - 2(10×-1 + 7)

6 = - 2(-10 + 7)

6 = - 2(-3)

6 = 6 (true)

Good luck !

Answer:

n = -1 OR -1 = n

Step-by-step explanation:

6 = -2(10n +7)

First we remove the brackets by multiplying the inner numbers by -2

6 = -20n - 14

Then we add 14 on both sides

20 = -20n

We make n the subject and divide both sides by -20

n = -1 OR -1 = n

Answer:

29 degrees

Step-by-step explanation:

Note how both triangles are isosceles triangles, which mean two angles will be equivalent. In the triangle with the marked angle measurement, since the total of angles in a triangle is 180, then the measurement of the unmarked angles have a sum of 180-64, which is 116. Then, as stated before, this triangle is isosceles, so the measurement of each unmarked angle is 116/2, which is 58.
Next, notice how the angle below angle x in that triangle shares a line with one of the 58 degree angles. This means that angle is 180-58, which is 122. Now, since the total of angles in a triangle is 180 and the triangle is isosceles, then angle x is (180-122)/2, which is 58/2, or 29 degrees

Step-by-step explanation:

The required fractions for 2/3, 3/4, and 5/6 with a denominator of 12 are 8/12, 9/12, and 10/12 respectively

Given the following fractions

2/3, 3/4 and 5/6

We are to write as equivalent fractions with a denominator of

12​

For the fraction 2/3;

[tex]= \frac{2}{3} \frac{4}{4}\\= \frac{2 \times 4}{3 \times 4} \\= \frac{8}{12}[/tex]

For the fraction 3/4

[tex]= \frac{3}{4} \frac{3}{3}\\= \frac{3 \times 3}{4 \times 3} \\= \frac{9}{12}[/tex]

For the fraction 5/6;

[tex]= \frac{5}{6} \frac{2}{2}\\= \frac{5 \times 2}{6 \times 2} \\= \frac{10}{12}[/tex]

Hence the required fractions for 2/3, 3/4, and 5/6 are 8/12, 9/12, and 10/12 respectively

The standard deviation is 10.38

Step-by-step explanation:

Given;

Variance, v = 107.76

mean, x = 34.2

The standard deviation is given by;

standard deviation = √variance

standard deviation = √107.76

standard deviation =  10.381

standard deviation = 10.38 (two decimal places)

Therefore, the standard deviation is 10.38

Step-by-step explanation:

Answer:

1/6 becomes 4/24 and 3/8 becomes 9/24.

Step-by-step explanation:

The LCD of the denominators is 24 because that is the lowest number that 6 and 8 are both related too (6 times 4 is 24, and 8 times three is 24). Since 6 goes into 24 4 times, multiply 1 (the numerator) by 4 and you get 4. Since 8 goes into 24 3 times, multiply 3 (the numerator) by 3 and you get 9.

Answer:

x=-4

When x is -4, the y value (which is what the function spits out) is 8.

Answer:

Step-by-step explanation:

a) Mean the sum total of the given variables divided by the sample size given.

Mean = (Σx)/N

Σx = 1550 +1650 +1600 +1650 +1500 +1200 +1650+ 1800+ 1200 +1050 +1650+ 1850

Σx = 18,350

N = 12

Mean = 18,350/12

Mean = 1529.17

b) Median is the data at the middle if the given dataset after rearrangement. Arrangement can either be in ascending or descending order.

Rearranging the dataset in ascending order of magnitude.

1050 1200 1200 1500 1550 (1600 1650) 1650 1650 1650 1800 1850

It is seen that two values 1600 and 1650 are values that falls in the middle, hence we will take their average.

Median = 1600+1650/2

Median = 1625

c) Mode is the value in the dataset that occur the most i.e value with the highest frequency. According to the data only 1650 occurs 4 times, hence the mode of the data is 1650.

d) Midrange of the data is the average of the highest values and the Lowest value.

Midrange = Maximum value+Minimum value/2

Max value = 1850

Min value = 1050

Midrange = 1850+1050/2

Midrange = 2900/2

Midrange = 1450

4) No, the resulting statistics are not representative of the population of all TVs that are 60 inches and​ larger because it is given that the dataset provided is for the selling prices of TVs that are 60 inches or larger and rated as a​ "best buy" by a popular magazine, therefore we can conclude that, the dataset is representative of the best type of TVs that are 60 inches and​ larger and not all the sets of TVs

- The measure of dispersion relevant is the STANDARD DEVIATION other than the measures of central tendencies above because it shows how the selling prices of the different best TVs varies especially that of variation from the mean.
