Answer:

$2/3d

Step-by-step explanation:

since it says that if she were to buy all three beanie babies, she'd spend all of her money, this means that since she bought 1, she only used up 1/3 of her money, or $1/3d.

so, after buying the beanie baby, she has $2/3d left.

Answer:

7

Step-by-step explanation:

x+y=30

x-y=16

2x=14

therefore x=7 and y=23.

the smallest number is 7.

btw jungwoo = best boy

Step-by-step explanation:

Let x be the smallest number

According to the question,

(Let the two numbers be x and y)

x+y=30

= x=30-y

Now,

y-x=16

= y=16+30-y

= 2y=46

= y =23

Also,

x=30-23

= 7

The value of the smallest number is 7

The other number is 23

Answer:

W = 0

Z = -2

Step-by-step explanation:

While simplyfying the equation, i noticed that one is 24 and the other is -24, which meant that one value is non existent, and after i found out that w = 0 imputing the reslut made that easier

Answer:

  x ≤ -14

Step-by-step explanation:

We assume you want to solve ...

  x/(-7) +14 ≥ 16

Subtract 14, then multiply by -7.

  x/(-7) ≥ 2 . . . . subtract 14

  x ≤ -14 . . . . . . multiplying by a negative number reverses the inequality

Answer:

D.8

Step-by-step explanation:

Since your chance of success is only 1 out of 5 or rather, 20%, so

40 divided by 5 equals 8, so the answer is D.

(Of course, this is just what SHOULD happen, not what CERTAINLY can happen.)

Expected number of answers to be correct = 8.

Measure of the likelihood of an event happening is called Probability. Probability can be between 0 to 1. 0 means the event cannot happen, 1 indicates the specific event. The sum of the probabilities of all events in the sample space is 1.

Probability can be defined as the ratio between the number of favorable outcomes and the total number of outcomes of an event. For a trial with “n” number of results, the number of favorable outcomes can be denoted by x. The formula for calculating the probability of an event is as follows.

Probability (Event) = Favorable Outcome/Total Outcome = x/n  

Given,

Number of questions = 40

One of 5 choices is correct

then, probability of getting correct option = 1/5

Number of correct answers = 40 × 1/5 = 8

Hence, 8 answers are expected to be correct.

Answer:

The 90% confidence interval for the mean combined fuel economy for Ford Explorers is between 22.95 and 23.63 mpg.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 16 - 1 = 15

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 15 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.7531

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.7531\frac{0.78}{\sqrt{16}} = 0.34[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 23.29 - 0.34 = 22.95 mpg

The upper end of the interval is the sample mean added to M. So it is 23.29 + 0.34 = 23.63 mpg

The 90% confidence interval for the mean combined fuel economy for Ford Explorers is between 22.95 and 23.63 mpg.

Answer:

By using 3-month weighted moving average method -

Forecasts for the 4th month = 5400

Forecasts for the 5th month = 5530

By using Exponential smoothing method -

Forecasts for 3rd month = 5300

Forecast for 4th month = 5350

Forecast for  5th month = 5475

Step-by-step explanation:

To find - Calculate the forecasts for the 4th and 5th months using 3-month weighted moving average method.

Calculate the forecasts for 3rd, 4th and 5th months, using exponential smoothing method.

Proof -

Given that,

month           1            2              3              4

sales         5100       5500     5400        5600

F(4) = 0.6 A(3) + 0.3 A(2) + 0.1 A(1)

      = 0.6 [ 5400] + 0.3 [ 5500] + 0.1 [ 5100]

      = 3240 + 1650 + 510

      = 5400

⇒forecasts for the 4th month = 5400

Now,

F(5) = 0.6 A(4) + 0.3 A(3) + 0.1 A(2)

      = 0.6 [ 5600] + 0.3 [ 5400] + 0.1 [ 5500]

      = 3360 + 1620 + 550

      = 5530

⇒forecasts for the 5th month = 5530

Now,

Given that, the exponential smoothing constant α=0.5

Month                   Sales                           Forecast

1                             5100                            5100

2                            5500                           5100 + 0.5(5100 - 5100) = 5100

3                             5400                          5100 + 0.5(5500 - 5100) = 5300

4                             5600                          5300 + 0.5(5400 - 5300) = 5350

5                                                                 5350 + 0.5(5600 - 5350) = 5475

∴ we get

By using Exponential smoothing method -

Forecasts for 3rd month = 5300

Forecast for 4th month = 5350

Forecast for  5th month = 5475

Answer-

77

Step-by-step explanation:

i rounded 76.67% (which was the exact percentage of 46 out of 60)

2- 77%

Answer:

About 76.5% (77%)

Step-by-step explanation:

well start with the simple fractions. 40/60 is 2/3 which is 66.66666 repeating.

If we know it increased at least 5 more that is 45/60 which is 3/4, since 15 * 4 = 60, so 15 * 3 = 45.

We could say without getting too specific that every point will have about a 1.5 or more % increase since if it was out of 100 points every 1 question is +1 % and 50 points every question is +2 %. Since this is 60 it will be roughly about 1.6%

Ok the point is, about 76.5% (77%)

Step-by-step explanation:

The m’s would all be the same number.Another way of adding the same number to each other would be to multiply that number by the number of times you want to add it to each other.

With m + m + m you are adding it 3 times.

So instead multiply m by 3:

The answer is 3m
