100 POINTS!!!!!! the following stem and leaf plot shows the number of hours that mrs. dixon's students spent on their pre calc work last week. what is the mean absolute deviation for the data

Answer:

Step-by-step explanation:

devide both sides by 4 it will be:

x^2 +3x -3/2 = 0

Answer:

"Spin the spinner 5 times with 4 equal segments. One of the segment represents vanilla on either the spinner as well as three parts reflect certain flavors" would be the right answer.

Step-by-step explanation:

The actual probability of the given scenario will be:

⇒  [tex](1-\frac{1}{4})^5[/tex]

⇒  [tex](1-0.25)^5[/tex]

⇒  [tex](0.75)^5[/tex]

On solving the power, we get

⇒  [tex](0.237304)[/tex]

Now on multiplying the above value in 100, we get

⇒  [tex]23.73[/tex]%

Approximately 23.73% chance vanilla was not chosen by either of the five. So that the above is the right answer.

Answer:

Spin a spinner with four equal sections five times. On the spinner, one section represents vanilla and three sections represent other flavors.

Answer:

i think is 75

Step-by-step explanation:

Answer: 105

Step-by-step explanation:

3-2 is 180-75 which gives you the answer.

Answer:

AB = 6.53

Step-by-step explanation:

cos theta = adjacent/ hypotenuse

cos 40 = 5/ AB

AB cos 40 = 5

AB = 5/ cos 40

AB = 6.527036447

Round to the nearest hundredth

AB = 6.53

Answer:

[tex](2 {n}^{2} ) ^{4} \\ 2 \times 2 \times 2 \times 2 \times {n}^{2 \times 4} \\ {2}^{4} \times {n}^{8} \\ = 16 {n}^{8} [/tex]

Answer:

7/16

Step-by-step explanation:

Answer:

I'll edit the answer and try to answer it, but where is the graph?

Answer:

C: g(x)= x- 3

Step-by-step explanation:

translated 3 units down means you go 3 down on the y-axis. Therefore it is g(x)= x-3

Step-by-step explanation:

4x + 5y = 62 | ×5 |

5x – 3y = 22 | ×4 |

20x + 25y = 310

20x – 12y = 88

_____________--

37y = 222

y = 222/37

y = 6

4x + 5y = 62 | ×3 |

5x – 3y = 22 | ×5 |

12x + 15y = 186

25x – 15y = 110

_____________+

37x = 296

x = 296/37

x = 8

Answer:It would be -5 and 4

Step-by-step explanation:

Answer:

Root 181

Step-by-step explanation:

         Using distance formula, we know that the answer will be the square root of 181. Unfortunately, this is not a perfect square, and it is prime, so that number will remain the same.

Distance Formula: [tex]\sqrt{(13-4)^{2} + (7+3})^2} = \sqrt{181}[/tex]

Hope this helped!

Answer:

i think its the first one

Step-by-step explanation:

Answer:

The range is 14.

Step-by-step explanation:

To find the range in a data set, you have to subtract the lowest number from the highest number in the set. The highest number is this set was 32. The lowest was 18. 32-18=14. Thus, the answer is 14.

Answer:

multiplication i think? correct me if im wrong:)

Step-by-step explanation:

bye.

The answer is [ C. Multiply ]

The inverse operation of division is multiplication and vice versa.

The inverse operation of subtraction is addition and vice versa.

Solve for x.

x/6.8 = 5

~Multiply 6.8 to both sides

x/6.8 * 6.8 = 5 * 6.8

~Simplify

x = 34

Best of Luck!

Answer:

[tex] $$\sum_{n=1}^{5} 6(2^{n-1}) $$ [/tex]

Step-by-step explanation:

6 + 12 + 24 + 48 + 96 =

= 6 + 6 * 2 + 6 * 4 + 6 * 8 + 6 * 16

= 6 + 6 * 2^2 + 6 * 2^2 + 6 * 2^3 + 6 * 2 * 4

= 6 * 2^(n - 1)

[tex] $$\sum_{n=1}^{5} 6(2^{n-1}) $$ [/tex]

Answer:

3/8

Step-by-step explanation:

Find the height of the trapezoids

20 - 10 = 10

10/2 = 5

Find the area of the trapezoids

5*(20+10)/2 = 75

The formula for the area of the trapezoid is the height * the bases added together divided by 2

75*2(this is because there are 2 trapezoids) = 150

Put this to proportion of the total area of the dart board

150/[tex]20^{2}[/tex] = 150/400 = 3/8

3/8 is the probability that you score 3 points

Answer:

must not be

Step-by-step explanation:

The whole thing equals 360 degrees

Angle B and Angle D are equal; which equals 190 degrees.

Add Angle A to 190 degrees; which is 86 + 190 = 276.

Subtract 360, which is what the whole thing equals, and 276, which is the known angle added together, and you get 56.

In order for this to be a parallelogram, the opposite angles need to be equal.

Since they are not, the answer is must not be.

Answer:

$93,996

Step-by-step explanation:

i = prt

i = ($53,712)(.15)(5)

i = $40, 284

$40, 284 + $53,712

$93,996

Answer:

$92996

Step-by-step explanation:

Using the given formula :

I = P × R × T

I = 53712 × 15/100 × 5

I = $40284

He has = 40284 + 53712 = $93996

Answer:17.32

Answer:

120 square centimeters

Step-by-step explanation:

Answer:

x = -9

Step-by-step explanation:

-4x = -1/2(10x + 18)

Distribute

-4x= - 5x -9

Add 5x to each side

-4x+5x = -5x+5x -9

x = -9

Answer:

25.8

Step-by-step explanation:

WITH WHAT!!!!!!!!!!!!

Answer:

I'm gonna rewrite each sentence in a way that lines up a little more with the Algebraic expression you would end up with. Just keep in mind that either way of saying it is correct.

1. "8 times some number (a variable) minus 5"

8x-5

2. "13 plus some number"

13+x

3. "Some number over 7"

x/7 or x÷7

4. "d number of drinks times 3.50 plus 12 equals how much John spent (we'll call it J)"

12+3.50d = J

5. "Stacey bowled x number of games times the cost of one game (call it B) plus the cost of the shoes (call it P) which equals how much they spent (call it S)"

xB+P = S

6. "675.95 dollars was spent at the mall by a number of players (call it P) to equal the total cost per player)"

$675.95÷p (players) = 675.95/p (dollars/player)

Essentially you're making expressions or equations out of numbers you know and putting in variables as place holders for numbers you don't know. The variables can be whatever letters you like, but you'll want to write what each variable represents down nearby. Otherwise the reader/your teacher won't know what's what.

Answer: x=4

Step-by-step explanation:

Answer:

x=4

Step-by-step explanation:

6x+2=26

Subtract 2 from both sides to isolate the variable

6x=24

Divide by 6

x=4

Answer:

The sum of all the angles of any triangle is 180°

So, 180 - (53 + 48) = 180 - 101 = 79

f = 4

Answer:

3/2

Step-by-step explanation:

Its because its saying the largest box to the smallest.

since the largest box has a side of 3 it should be on top and the smallest is 2, should be on the bottom.

Ignore all negetive fraction because they are useless.

Answer:

Use the sum of angle measures rule.

Step-by-step explanation:

If you are given two angles and one missing angle, it's good to remember that all angles add up to 180°.

You can add the the given angles measurements, and subtract them by 180. You should then get the missing angle measure.

Brainilest Is Appreciated.

Answer:

No because 21 is close to it.

Step-by-step explanation:

To be considered an outlier, it would need to be a farther distance such as the distance from 28 to 21.

Hope this helps!!! PLZ MARK BRAINLIEST!!!

Answer:

No. it's close to 21.

Step-by-step explanation:

There's a formula for fidning out if something is an outlier or not but i forgot, pff, look it up :P

Answer:

i think its about 5 pounds idk please tell me if im wrong..

Step-by-step explanation:
