Find the two numbers . State the smallest number?
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

Jane had $d to buy three Beanie Babies. (In our problem, they all cost the same).
If she were to buy all three, she’d spend all her money. Instead, she bought just one.
How much money does Jane have left after buying the Beanie Baby? Brainliest to correct answer:)
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.

Please helppp
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.
What is probability?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:
x ≤ -14

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

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?
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.
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.

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