Answer:
1 no
2 yes
3 no
4 no
Step-by-step explanation:
2 ÷ □ =2/3, □ ÷ 8 = 3/8 is true for x is true which equation choose is yes.
What is Division?A division is a process of splitting a specific amount into equal parts.
We have to choose yes or no to tell if the number 3 will make each equation true.
2÷□=3/2
To get 3/2 we have to divide two by three.
2/3=3/2
These are not equivalent so it is not yes.
The other expression 2 ÷ 6 = □
2 ÷ 6=1/3 which is not 3, so it is no.
The third expression
2 ÷ □ = 2/3
When we put 3 in the blank place we get two divided by three.
2 ÷ 3=2/3
Which is true so answer is yes for 3.
□ ÷ 8 = 3/8
When we put three in the blank we get three divided eight which is true.
3÷ 8 = 3/8 which is yes for 3.
Hence, 2 ÷ □ =2/3, □ ÷ 8 = 3/8 is true for x is true which choose is yes.

Why is stock data calculated using the subtraction and addition method instead of a simple moving average? PLEASE HURRY I AM TAKING A TEST
Answer:
The moving average (MA) is a simple technical analysis tool that smooths out price data by creating a constantly updated average price. The average is taken over a specific period of time, like 10 days, 20 minutes, 30 weeks or any time period the trader chooses. There are advantages to using a moving average in your trading, as well as options on what type of moving average to use. Moving average strategies are also popular and can be tailored to any time frame, suiting both long-term investors and short-term traders.
Step-by-step explanation:
One disadvantage to solving systems using substitution is that isolating a variable often involves dealing with messy fractions. There is another method for solving systems of equations: the addition/subtraction method.
In the addition/subtraction method, the two equations in the system are added or subtracted to create a new equation with only one variable. In order for the new equation to have only one variable, the other variable must cancel out. In other words, we must first perform operations on each equation until one term has an equal and opposite coefficient as the corresponding term in the other equation.

After school Philippe spent 1 3/4 hours at baseball practice, 2 1/4 hours on homework, and 1/4 hour getting ready for bed. About how many hours after school will he be ready for bed. Explain
Answer:
4 hours. 1 3/4 is about 2, and 2 1/4 rounds to 2. 1/4 would round to 0, but it would not affect the estimate's accuracy much because we rounded up by 1/4 on 1 3/4 already. Philipe spent about 4 hours on activities.

Sasha is the manager at a factory.
Last weekend 15 employees assembled 390 identical wardrobes.
Sasha wants 1200 of these wardrobes to be assembled next weekend.
How many employees does Sasha need next weekend?
You must show your working.
The number of employees Sasha would need next weekend are = 46
Calculation of total employeesFor a weekend, 15 employees = 390 wardrobes
The number of wardrobes to be assembled next weekend= 1200
If 390 wardrobes = 15 employees
1200 wardrobes = X employees
Make x the subject of formula,
X = 1200 × 15/390
X = 18000/390
X = 46
Therefore, the number of employees Sasha would need next weekend are = 46

Why do you think we need to convert normal distribution to standard normal distribution?
Answer:
The standard score (more commonly referred to as a z-score) is a very useful statistic because it (a) allows us to calculate the probability of a score occurring within our normal distribution and (b) enables us to compare two scores that are from different normal distributions
Dimple volunteered 32 hours last month at a local animal shelter. This is 20% of the total hours that she has volunteered this year. How many hours did she volunteer this year?
If she was to volunteer 32 hours and it is worth 20%, then that means 32 hours is 1/5 of her yearly hours. If you were to multiply her volunteer hours by five, then you are getting the year number of hours she has volunteered.
32 x 5 = 160
So, she volunteers 160 hours this year.

According to the admissions director of a certain college, approximately 11% of the 250 freshmen admitted had
applied using the early decision option. Suppose that we took random samples of 20 freshmen from this
population and computed the proportion of freshmen in each sample who had applied using the early decision
option. We can assume the admissions director's claim is true.
What will be the shape of the sampling distribution of p?
Answer:
Skewed to the right
Step-by-step explanation:
We have a right-skewed sampling distribution because the population proportion is so extreme relative to the sample size that there are fewer than 10 expected successes per sample.
The shape of the sampling distribution of p is skewed to the right because there are fewer than 10 projected successes per sample.
What is a histogram?It is defined as the numerical data representation in the graph with the help of a bar without space. The histogram gives an idea about the data's approximate distribution.
We have:
11% of the 250 freshmen admitted had applied using the early decision option.
Total number of samples = 20
It is given that the admissions director's claim is true.
As we can see from the data shape of the sampling distribution of p is skewed to the right because there are fewer than 10 projected successes per sample since the population proportion is so excessive in comparison to the sample size.
Thus, the shape of the sampling distribution of p is skewed to the right because there are fewer than 10 projected successes per sample.

Answer:
5 out of 25
Step-by-step explanation:
The amount of apple fritters is 2 out of ten orders. 2/10 simplifies to 1/5. If u put 1/5 next to x/25 on a piece of paper, u can see that 5 times 5 will give u 25. This means that u should also multiply 1 times five to find the value of x. 1x5=5. So, 5 out of 25 pastries should be apple fritters. Hope this is right, let me know!
Pilot Shop is a catalog business providing a wide variety of aviation products to pilots throughout the world. Maynard Shephard, the recently hired assistant controller, has been asked to develop a cost function to forecast shipping costs. The previous assistant controller had forecast shipping department costs each year by plotting cost data against direct labor-hours for the most recent 12 months and visually fitting a straight line through the points. The results were not satisfactory.
After discussions with the shipping department personnel, Maynard decided that shipping costs could be more closely related to the number of orders filled. He based his conclusion on the fact that 10 months ago the shipping department added some automated equipment. Furthermore, he believes that using linear regression analysis will improve the forecasts of shipping costs. Cost data for the shipping department have been accumulated for the last 25 weeks. He ran two regression analyses of the data, one using direct labor-hours, and one using the number of cartons shipped. The information from the two linear regressions follows:
Regression 1 Regression 2
Equation SC = 804.3 + 15.68DL SC = 642.9 + 3.92NR
R-squared .365 .729
Standard error of the estimate 2.652 1.884
t-value 1.89 3.46
where:
SC = total shipping department costs DL = total direct labor-hours
NR = number of cartons shipped
Required
1. Identify which cost function (regression 1 or regression 2) Pilot Shop should adopt for forecasting total shipping department costs and explain why.
2. If Pilot Shop projects that 600 orders will be filled the coming week, calculate the total shipping depart- ment costs using the regression you selected in requirement 1.
3. Explain two or three important limitations of the regression you selected in requirement 1, and identify one or two ways to address the limitations. Specifically include in your discussion the effect, if any, of the global nature of Pilot Shop’s business.
Step-by-step explanation:
1. The second regression should be adopted for forecasting because the R² is higher in this regression and the standard error is also smaller. the t value is also better in this regression compared to the first
2. Using regression 2, the estimated shipping cost is to be calculated here.
= 642.9 + 3.92NR
NR = 600
642.9 + 3.92X600
= 642.9 + 2352
= $2994.9
This is the estimated shipping cost.
3. The limitations could be due to error in data, the data could be unreliable because of the presence of outliers. Pilot shop is a global business so there is another factor to adds to the limitations, as this costs of buying and shipping are affected by fluctuations in exchange rate and variations in the global market.
