1.5(6)

Answer:

Step-by-step explanation:

I chose 9 because first you have to add 4+2 because it's in parenthesis and the other with parenthesis has no other numbers so 4+2 first then 4+2 is 6 then you multiply 6 by the 3 in the parenthesis because it is in the parenthesis then divide by 2 because 1/2 is basically dividing by 2

Find the value of x.

F) 6m
G) 7.5m
H) 15m
I) 21m

Answers

Answer:

x = 6 m

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here A = 60, h = 8, a = 9 and b = x , thus

[tex]\frac{1}{2}[/tex] × 8 × (9 + x) = 60, that is

4(9 + x) = 60 ( divide both sides by 4 )

9 + x = 15 ( subtract 9 from both sides )

x = 6 m

Find the mean absolute deviation for the set below:

62, 71, 83, 110, 501, 94, 227

Answers

Answer:

(MAD) mean absolute deviation: 114.2

Step-by-step explanation:

Mean: 62 + 71 + 83 + 110 + 501 + 94 + 227 = 1,148/7 = 164

164 - 62 = 102

164 - 71 = 93

164 - 83 = 81

164 - 110 = 54

164 - 501 = 337

164 - 94 = 70

164 - 227 = 63

Mean Absolute Deviation: 102 + 93 + 81 + 54 + 337 + 70 + 63 = 800/7 = 114.2

Answer:

Step-by-step explanation:

First, add all the numbers and count the total amount of numbers.

Once you've done that find the mean by dividing the total of the numbers by how many numbers you have.

Next make a chart, have 2 parts in the chart. Make boxes for however many numbers you have. Make another row in the chart for the distance from the mean ( how many numbers is it from the mean.)

Add all the "distance from mean" numbers and divide by total numbers, If a decimal, round up or down.

Then, you have the M.A,D ( Mean Absolute Deviation )

Given the general form: ax + by = c How can we rewrite this general for the equation of a line, so that it is in slope intercept form? (a, b, and c are real numbers other than 0.) Hint: Substitute in values for a,b,c if you are confused) YOUR FINAL ANSWER SHOULD HAVE a,b,c in it. *

Answers

Answer:

[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex] or [tex]y = \frac{c-ax}{b}[/tex]

Step-by-step explanation:

Slope intercept form is y = mx + b, so you rewrite it to equal y.

ax + by = c

by = c - ax

y = (c - ax) / b

[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex]

In the image, all the lines overlap. This proves that all the equations are equal to each other.

What is the measure of an angle, in degrees, if its supplement is six times its complement?

Answers

Answer:

72 degrees.

Step-by-step explanation:

We can name the measure of the angle x.

We can name the measure of the complement of it y.

Note that complementary angles add up to 90 degrees and supplementary angles add up to 180 degrees.

Using this info, we can set up two equations.

x+y=90

x+6y=180

Subtract the first equation from the second to eliminate x. You can do both ways, but I prefer to keep the equation positive.

x+6y=180

-x -y -90

5y=90

Divide both sides by 5.

y=18

The complement is 18, now we can plug that in to find x.

x+18=90

Subtract 18 from both sides.

x=72

The measure of the angle is 72 degrees.

no 6^2 + 8^2 ≠ 12^2 so this is not a right triangle

Step-by-step explanation:

The Pythagorean theorem tells you if you have a right triangle

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

6^2 + 8^2 = 12^2

1) Not True, because angles on a straight line=180 degrees. So 72+90=162 not 180, 180-72=108, angle 3 is 108 degrees.
2) Angle 5=72 degrees because angle 5 is alternate to angle 72 degrees.

Answer:

72 km/hr

Step-by-step explanation:

First, convert from meters to kilometers. 20 meters is 0.02 kilometers.

Now that you have km/s, convert 0.02 km/s into km/h by multiplying it by the number of seconds in an hour. There are 3,600 seconds in an hour. Multiply 0.02 km/s by 3,600 secs/h to get 72km/h!

This is a discrete random variable because the set of possible values is an interval. This is a continuous random variable because the set of possible values is an interval. This is a discrete random variable because it has a finite sample space. This is a continuous random variable because it has a finite sample space.
