Answer:

If the mean is $12, her eighth earning was $10.

What is the data's Mean?

By dividing the total number of entries by the sum of the given numbers, the mean, or average, of the given data set is obtained.

To put it another way, the mean is equal to the sum of all the data divided by the total number of data.

Laura moved 8 Iawns. Her pay for seven lawns was $12, $10, $15, $15, $10, and $9.

Let's say she was paid $x for the eighth year.

being $12 on average

Using the formula, mean

=(12+10+15+15+15+10+9+x)/(8)

 =(86+x)/8

so, (86+x)/8=12

     (86+x) =96

       x =10

Hence, Laura earned $10 the eighth time.

2(3−7)+6=x−14+6 What is the value of x? Please hurry.

Answers

2(3-7)+6=x-14+6 \n \n 2(3 - 7) = x - 14 \ / \ cancel \ 6 \ on \ each \ side \n \n 2 * -4 = x - 14 \ / \ simplify \n \n -8 = x - 14 \ / \ simplify \n \n -8 + 14 = x \ / \ add \ 14 \ to \ each \ side \n \n 6 = x \ / \ simplify \n \n x = 6 \ / \ switch \ the \ sides \ around \n \n

The final result is x = 6.
2(3-7)+6=x-14+6
=6-14+6=x-14+6
=6-6-14+6=x-14+6-6
=-14+6=x-14
=-14+14+6=x-14+14
=6=x

The manager of a video game store found that 35 of the 140 people who preordered the latest baseball game canceled their orders the day before the game was released. He used that data to create a simulation to predict the probability that future customers will cancel their preorders.

Answers

chart ,a table , or a graph

Answer: I believe this is unfinished. The rest of the question is:

According to the manager’s model, what is the probability that two customers who preorder the newest golf game will both cancel their orders the day before the game is released?

O 1/16

O 1/8

O 1/4

O 1/2

The answer to this question is 1/16.

Step-by-step explanation: Take the people that canceled their orders over the total number of people that ordered to get 35/140, which simplifies to 1/4. This problem is an independent event, so take 1/4 and multiply it by itself (1/4 times 1/4) to get 1/16.

Sorry if this doesn't make sense.

suppose a and b give the population of two states where a > b. compare expressions and tell which of the given pair is greater or if the expressions are equal. 1. b/a+b and 0.52. a+13c and b+13c is the population of a third state3. a-b/2 and a-b/24. a+b and 2b5. 5(a+b) and (a+b)5

Answers

Answer:

We are given that a>b.

1)(b)/(a+b) and 0.5

we know that a>b

⇒ a+b>b+b

⇒a+b>2b

⇒  (b)/(a+b)<(1)/(2)=0.5

2) a+13c and b+13c is the population of a third state.

so, a+13c>b+13c

3) both the given expressions are same i.e.

(a-b)/(2)

4) a+b and 2b

we know that a>b

⇒ a+b>b+b

⇒a+b>2b.

5) both the given expressions are same i.e. 5(a+b) or (a+b)5 since we have to multiply (a+b) and 5.

In at least 100 words independently write your response to the statement, "Anyone can do well in math."

Answers

Answer:

I believe that this is true. Anyone can do well in math, not everyone. The main difference being that if EVERYone could, that means every one person in the world, no matter the circumstance, so by saying ANYone, it's saying that however many people in the world want to do it, can do it, if they try and put in the work. Math is not biased against any one person, nor is it  favored for any one person. Any person who studies, or learns it can do well in math. Someone who has never learned anything about math will not do well at all. So, yes, ANYone can do well, but not EVERYone.

Not 100 words, but should do trick if you just add in some extra words between phrases, and substitute some words with one or two synonyms.

#3.A. 1 over 3 minus 1 over x equals 1 over 5
#4.C. 12 minutes
#5.B. 1 over 4 plus 1 over 3 equals 1 over x

Answer:

1) option: A (120 minutes)

2) option: A(96 minutes)

3) option: A

4) option: C

5) option: B

Step-by-step explanation:

Ques 1:

Let the total work be '240'  

                      filling pipe                  empty pipe                filling+empty pipe

 Time                 40 min                         60 min                                x

Efficiency          240/40=6                   240/60= -4                        6-4=2

The efficiency of empty pipe is negative as it lead to more time in filling.

Hence the time taken by both the pipe will be   (240)/(2) =120 minutes.

Hence, option A is correct.

Ques 2:

Let the total work be '960'

                                 Annmarie             Gladys               Annmarie+Gladys

Time                           240 min                160 min                     x

Efficiency                  960/240=4            960/160=6             6+4=10

Hence, the time taken if they work together is:  (960)/(10)=96 minutes

Hence, option A is correct.

Ques 3:

Let the total work be '1'  

                                 Brody           Hudson          Brody+Hudson

Time                          3 min                   x min                   5 min                    

Efficiency                     1/3                   -1/x                          1/5

the efficiency of Hudson is negative as he is taking out the candies.

since, efficiency of Brody+efficiency of hudson= efficiency of both

that means (1)/(3)-(1)/(x)=(1)/(5)

Hence, option A is correct.

Ques 4:

Let the total work be '60'.

                          Leanne                   Karl                   Leanne+Karl

Time                      30 min                20 min                      x                  

Efficiency                 2                         3                              5

Hence, the time taken by both of them is: (60)/(5)=12 \text{minutes}

Hence, option C is correct.

Ques 5:

Let the total work be '1'

                               Genna               Claude                   Genna+Claude

Time                         4 hrs                      3 hrs                          x hrs

Efficiency                   1/4                           1/3                          1/x

Since,  efficiency of Genna+Efficiency of Claude=Efficiency of both

that means    (1)/(4)+(1)/(3)=(1)/(x)

Hence, option B is correct.
