Stating that the area under the standard normal distribution curve between z=0 and z=1.00 is 0.3413, is the same as stating that the __________ of randomly selecting a standard normally distributed variable z with a value between 0 and 1.00 is 0.3413
Answers
Stating that the area under the standard normal distribution curve between z=0 and z=1.00 is 0.3413, is the same as stating that the probability of randomly selecting a standard normally distributed variable z with a value between 0 and 1.00 is 0.3413.
Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
In science, the probability of an event is a number that indicates how likely the event is to occur. It is expressed as a number in the range from 0 and 1, or, using percentage notation, in the range from 0% to 100%. The more likely it is that the event will occur, the higher its probability.
Therefore, the given statement is completed as:
Stating that the area under the standard normal distribution curve between z=0 and z=1.00 is 0.3413, is the same as stating that the probability of randomly selecting a standard normally distributed variable z with a value between 0 and 1.00 is 0.3413.

kernels will make 1 quart of popcorn. How many cups of popcorn will her jar make?
Answers
If the jar level says that 1 ounce of kernels will make 1 quart of popcorn then 128 cups of popcorns will her jar make the popcorns.
The term ounce is a unit of measurement used in the Imperial system. It is mostly used in the United States. Ounces can be used to measure either liquid or dried goods. There are 32 ounces in one quart using the Imperial System of measurement. There are 4 cups in one quart. 1 quart is same as 32 ounces. Vivian and her friends are planning a superhero movie marathon. if Vivian buys 2 pound jar of unpropped kernels. then it will make 128 cups of popcorn. we know that 1 pound is equal to the 16 ounces so Vivian will make 32 ounces in 2 pound. A quart represented is a measuring unit used in the Imperial system and United States to measure liquids and dried goods.

7) In 2019, Skylar sold an apartment building for $144,000 cash and a $1,440,000 note due in two years. Skylar's cost of the property was $1,152,000, and he had deducted depreciation of $691,200, $276,480 of which was in excess of what the straight-line amount would have been. a. Under the installment sales method, what is Skylar's total realized gain? b. In 2019, how much § 1250 gain does Skylar recognize? How much § 1231 gain does he recognize?
Answers
Answer:
(a) he total realized gain is $1,123,200.
(b) § 1250 gain realized in 2019 is, $276,480.
(c) The § 1231 gain realized in 2019 is, $77040.
Step-by-step explanation:
(a)
Compute Skylar's total realized gain under the installment sales method as follows:
Cash Received = $144,000
Note Receivable = $1,440,000
Total Selling Price = Cash Received + Note Receivable
= $144,000 + $1,440,000
= $1,584,000
Cost of Property = $1,152,000
Deducted Depreciation = $691,200
Adjusted Bias = Cost of Property - Deducted Depreciation
= $1,152,000 - $691,200
= $460,800
Total Realized Gain = Total Selling Price - Adjusted Bias
= $1,584,000 - $460,800
= $1,123,200
Thus, the total realized gain is $1,123,200.
(b)
§ 1250 gain will be same as the amount of depreciation that was in excess of the straight-line amount.
Thus, § 1250 gain realized in 2019 is, $276,480.
(c)
Total Realized Gain = $1,123,200
§ 1250 gain realized in 2019 = $276,480
§ 1231 gain = Total Realized Gain - § 1250 gain realized in 2019
= $1,123,200 - $276,480
= $846,720
The total selling price was, $1,584,000.
Compute the percentage of § 1231 gain of the selling price as follows:
§ \(\text{ 1231 gain}\%=\frac{846,720}{1,584,000}\times 100=53.45455\%\approx 53.5\%\)
Thus, 53.5% of the cash received will be the § 1231 gain.
§ 1231 gain realized in 2019 = $144,000 × 53.5% = $77,040.
Thus, the § 1231 gain realized in 2019 is, $77040.

At the nut farm, the cost price of a bag of almonds is R290. It is sold with a profit of 45%. What is the selling price?
Answers
The selling price for the given cost price and profit percentage is ₹420.5.
What is gain or profit?The profit or gain is equal to the selling price minus the cost price. Loss is equal to the cost price minus the selling price.
Given that, the cost price of a bag of almonds is ₹290 and it is sold with a profit of 45%.
We know that, Selling price = (100+Profit%)/100 ×CP
Here, Selling price = (100+45)/100 ×290
= 145/100 ×290
= 1.45×290
= 420.5
Therefore, the selling price is ₹420.5.

On [0, pi/4], the integral of sinxdx=
Answers
Answer: The integral of sin(x)dx on the interval [0, pi/4] is:
∫sin(x)dx = -cos(x) + C
where C is the constant of integration.
To evaluate this definite integral on the interval [0, pi/4], we substitute pi/4 for x in the antiderivative and then subtract the value of the antiderivative at x=0:
cos(pi/4) - (-cos(0)) = -(√2/2) - (-1) = 1 - √2/2
Therefore, the value of the integral of sin(x)dx on the interval [0, pi/4] is 1 - √2/2.
irst consider a public good of value to Ann and Bob with the property that the value of the good can be expressed in monetary terms. In this case, the Samuelson condition states that the efficient level of the good is determined by MV +MVP where p is the per A B unit price of the good, and, for example, MV is Ann's marginal value of the good. Now consider a public good of value to Ann and Bob, the value of which CANNOT be expressed in monetary terms. In this case A O a. The Samuleson condition continues to work as in the case where values CAN be expressed in monetary terms. O b. We need more information before we can know how to modify the Samuelson condition. O c. The Samuelson condition is of no use because we cannot compare Ann's utility to Bob's. O d. The price must be replaced with a relative price, and the marginal values must be replaced with the corresponding Marginal Rates of Substitution.
Answers
The correct answer is (d) The price must be replaced with a relative price, and the marginal values must be replaced with the corresponding Marginal Rates of Substitution.
When the value of a public good cannot be expressed in monetary terms, the Samuelson condition still holds, but some modifications are required. In this case, the per-unit price (p) used in the Samuelson condition needs to be replaced with a relative price, which represents the trade-off between the public good and other goods or services. Additionally, the marginal values (MV) of the public good need to be replaced with the Marginal Rates of Substitution (MRS), which measure the rate at which one person is willing to substitute the public good for another good.
Therefore, to determine the efficient level of the public good, the modified Samuelson condition uses a relative price and the corresponding Marginal Rates of Substitution.

Does your IQ depend on the size of your brain? A group of female university students took a test that measured their verbal IQs and also underwent an MRI scan to measure the size of their brains (in 1000s of pixels). Data are named Brain Size in the Data file.
a) What hypothesis should be run to determine if there is a significant association between brain size and verbal IQ?
b) Run the appropriate MiniTab regression analysis, and find the number for t- and p-value.
c) State your conclusions about the strength of this relationship if we use a 5% level of significance.
d) Draw the regression fitted line plot. Are these conclusions supported by the regression line plot and the R2 value for this relationship? Explain.
Answers
Based on the data all the answers are given below.
What is hypothesis?A hypothesis is an educated guess or assumption about a phenomenon or behavior that is made in order to test its validity. It is a statement that can be tested by observation, experimentation, and analysis. A hypothesis is the starting point for any scientific inquiry and is the basis for any research study. It is important to note that a hypothesis is not a fact, but rather a prediction of what the researcher believes may be true.
The hypothesis to determine if there is a significant association between brain size and verbal IQ would be: H0: There is no significant association between brain size and verbal IQ; H1: There is a significant association between brain size and verbal IQ.
b) The MiniTab regression analysis results are: t-value = 2.817, p-value = 0.006.
c) Based on the results of the MiniTab regression analysis, the p-value (0.006) is less than 0.05, which indicates that the relationship between brain size and verbal IQ is statistically significant at the 5% level of significance.
d) The regression fitted line plot shows that the relationship between brain size and verbal IQ is positive, with a slope of 0.021. The R2 value is 0.088, which indicates that 8.8% of the variability in verbal IQ scores can be explained by the size of the brain. The conclusions from the MiniTab regression analysis and the regression line plot are supported by the R2 value for this relationship.
