Solve for q: 2q- 12 = -40​

Answers

Answer 1

Answer:

q = -14

Step-by-step explanation:

2q - 12 = -40

Add 12  to both sides

2q - 12 + 12 = - 40 + 12

2q  = - 28

Divide both sides by 2

2q/2 = -28/2

q = - 14

Asanji stands at the edge of the top of a tall building and lobs a watermelon up into the air then proceeds to watch it fall to the street below (luckily it's empty because everybody is at home). The equation below represents the height, off the ground in meters, of the watermelon t seconds after Asanji has thrown it.

h = -4.9t^2 + 9.8t + 28

Approximately, how long does it take the watermelon to hit the ground? Round to the nearest tenth of a second.

Answers

9514 1404 393

Answer:

  3.6 s

Step-by-step explanation:

This is nicely solved by a graphing calculator. It takes about 3.6 seconds to hit the ground.

__

We notice that the vertical velocity is a multiple of the leading coefficient, so we can solve this by completing the square.

  0 = -4.9(t^2 -2t) +28 . . . . . for h = 0

  28 +4.9 = 4.9(t^2 -2t +1) . . . . . rearrange, add 4.9 to both sides

  32.9/4.9 = (t -1)^2

  1 +(1/7)√329 = t ≈ 3.5912. . . . . square root and add 1

It takes about 3.6 seconds for the watermelon to hit the street.

Jim got 46 out of 60 correct on a test. What is the best estimate of the percent Jim got correct ?

Answers

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%)

Find the two numbers . State the smallest number?

Answers

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

The number of items sold over a four-month period are: month 1 2 3 4 sales 5100 5500 5400 5600 Calculate the forecasts for the 4th and 5th months using 3-month weighted moving average method with weights of 0.6 for the most recent month and 0.3 for the next to the most recent month. Further, suppose that the exponential smoothing constant α=0.5. Then calculate the forecasts for 3rd, 4th and 5th months, using exponential smoothing method. Under the 3-month weighted moving average method, what is the forecast for the fourth month?

Answers

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

The Environmental Protection Agency (EPA) publishes fuel economy values that are known to be good estimates of the fuel economy a typical driver will achieve under average driving conditions. One of the fuel economy values the EPA publishes is a combined estimate, which represents a combination of city driving (55%) and highway driving (45%). A large car rental company has 16 Ford Explorers in their fleet. They collected fuel economy data from these cars and calculated the sample mean to be 23.29 mpg and sample standard deviation as 0.78 mpg.

Required:
The car rental company is willing to assume that the conditions are met for constructing a confidence interval. Use the collected data to construct a 90% confidence interval for the mean combined fuel economy for Ford Explorers.

Answers

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.

Jane had $d to buy three Beanie Babies. (In our problem, they all cost the same).

How much money does Jane have left after buying the Beanie Baby? Brainliest to correct answer:)

Answers

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.
