which of the following initial values of the variable y would result in the variable z being set to 2 after the code segment is executed?
When the following code section runs, the value of the variable y will be -2.
Given that,
We have to find when the following code section runs, what value will the variable y have? Assume the following input values:
The code mentioned above is explained in the section below.
Here, x=5, n=0, and the input values are 1–6.
So, x>3 is true.
Control will go to second if block and input y and z.
Now y=1 and z=2 and n=1
Next control goes to if(x) since x>0 which is true.
Now z=3 and x=4 and y=0 and n=0
Her n==0 so r=z- ++x => 3- (5) =>-2.
Hence r=-2
Therefore, the variable r=-2 is the output for the code.

Jesse takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A ferret weighs 2.1 pounds and costs $3.40 per week to feed, while a Labrador Retriever weighs 70 pounds and costs $7.50 per week to feed. Using weight as the explanatory variable, what is the slope of the line between these two points? Answer choices are rounded to the nearest hundredth.
$.06 / lb.
$16.56 / lb.
$1.73 / lb.
$1.62 / lb.
The slope of the line between these two points is $.06 / lb which is defined as the ratio of vertical extrade among points, the rise, to the horizontal extrade.
The slope is described because the ratio of the vertical extrade among points, the rise, to the horizontal extrade among the equal points, the run. . A slope with a extra absolute price shows a steeper line. The course of a line is both increasing, decreasing, horizontal or vertical. If a line is horizontal the slope is zero.
Let X1 = 2.1 pounds, Y1 = $3.4 and

a psychologist selects a random sample of 25 handicapped students and measures their manual dexterity scores. she uses this data to test the hypothesis that the mean dexterity score is different than 45.
A psychologist selects a random sample of 25 handicapped students and measures their manual dexterity scores, then if she wants to improve her precision she should use a larger sample size.
Each sample has an equal chance of being chosen as part of the sampling procedure known as random sampling. A randomly selected sample is intended to be a fair reflection of the entire population. By increasing sample size, you can improve the accuracy of your estimates, which means that the result will be more "statistically significant" for any given estimate or size of effect. The accuracy of the average results will increase with sample quantity. Smaller error margins and the identification of outliers in the data are two further benefits of larger sample sizes.
If they observe an effect that is almost significant, some researchers decide to increase their sample size. This is done rather than concluding that there is no effect because the researcher believes he is short on samples. Because the standard error is reduced as sample size increases, confidence intervals are narrower. c) The statement "there is a 95% likelihood that the population mean is between 350 and 400" is similar to the statement "there is a 95% confidence interval for the population mean is (350, 400)".

The price of the item increased by $24 from yesterday to today, which represents a 30% increase. To calculate this, divide the increase in price by the original price and multiply the result by 100%:
$24 / $80 x 100% = 30%
Therefore, the percentage increase in the price of the item from yesterday to today is 30%.
Two punches are made from steel bar stock 9-7/16 inches long. If one punch 4-1/64 inches long and the other is 4-3/32 inches long, how many inches of stock are wasted?
1-1 / 16''
1-21 / 64''
1-5 / 16''
After simplification of the given stock of steel bar , 1-21/64 inches of available stock are wasted.
As given in the question,
Length of the steel bar in stock = 9 7/16 inches
Length of one punch = 4 1/64 inches
Length of other punch = 4 3/32 inches
Simplification of the given data,
Length of steel bar - length of one punch
= 9 7/16 - 4 1/64
= 144/16 - 256/64
= (576 - 256)/64
= 320/64
=5 27/64 inches
Now,
subtract 4 3/32 from 5 27/64
= 5 27/64 - 4 3/32
= 347/64 - 131/32
=347/64 - 262/64
=(347-262)/64
=85/64
= 1 21/64inches
It means about "1 21/64" inches of the steel beam was wasted.
Therefore, after simplification the length of 1 21/64 inches of stock get wasted.

2) If you wish to save up $220,000 using an annuity, what monthly payment is required into the
annuity if the annuity has an APR of 8.0% compounded annually and you wish to reach your
savings goal in 30 years?
Answer:
$936.91
Step-by-step explanation:
To find the monthly payment required to save up $220,000 using an annuity with an APR of 8.0% compounded annually over 30 years, we can use the following formula:
payment = (goal * rate) / (1 - (1 + rate) ^-n)
In this formula, "goal" is the savings goal, "rate" is the monthly interest rate, and "n" is the number of payments.
To find the monthly payment, we need to first convert the annual interest rate to a monthly rate by dividing it by 12:
rate = 8.0% / 12 = 0.0067
Next, we need to find the number of payments by multiplying the number of years by the number of payments per year:
n = 30 years * 12 payments/year = 360 payments
Substituting these values into the formula, we get:
payment = (goal * rate) / (1 - (1 + rate)^-n)
= (220,000 * 0.0067) / (1 - (1 + 0.0067)^-360)
= $936.91
The monthly payment required to save up $220,000 using an annuity with an APR of 8.0% compounded annually over 30 years is $936.91.

An actuary is studying hurricane models. A year is classified as a high, medium, or low hurricane year with probabilities 0.1, 0.3, and 0.6, respectively. The numbers of hurricanes in high, medium, and low years follow Poisson distributions with means 20, 15, and 10, respectively. Calculate the variance of the number of hurricanes in a randomly selected year
The variance of the number of hurricanes in a randomly selected year is 12.5 .
Mean number of hurricanes in a randomly selected year =
0.1 × 20 + 0.3 × 15 + 0.6 × 10 = 12.5
Now, since the sum of independent Poisson random variables also follows Poisson distribution.
Thus, the variance of the number of hurricanes in a randomly selected year = Mean = 12.5
In both statistics and probability theory, variance is the predicted squared deviation of a binomial distribution from its sample proportion or sample mean.
Dispersion, or how far apart from the mean a set of data are from one another, is measured by variance. A few ideas that involve variance are descriptive research, statistical inference, testing hypotheses, goodness of fit, and Monte Carlo sampling.
The variance of a set of uncorrelated explanatory variables is equal to the sum of their variances, making it easier to manipulate mathematically than other measures of dispersion like anticipated absolute deviation.

An airplane flying at a given altitude begins its descent directly above a ground marker that is 20.42 miles from the runway. If the glide angle of the airplane to the ground is 30 degrees, how far did the airliner travel in the air from the point of descent until the plane touched ground? Round your answer to the nearest tenth mile.
Answer:
40.8 miles.
Step-by-step explanation:
To solve this problem, we need to know the distance that the airplane traveled in the air from the point of descent until it touched the ground. This distance is determined by the glide angle and the altitude of the airplane.
In general, the distance traveled in the air is equal to the altitude of the airplane divided by the sine of the glide angle. In this case, we are given the altitude and the glide angle, so we can calculate the distance traveled in the air as follows:
Distance = Altitude / sin(glide angle)
Plugging in the values from the problem, we have:
Distance = 20.42 miles / sin(30 degrees)
The sine of 30 degrees is 0.5, so the distance traveled in the air is:
Distance = 20.42 miles / 0.5
This simplifies to:
Distance = 40.84 miles
Rounded to the nearest tenth mile, the distance traveled in the air is 40.8 miles. This is the answer to the problem.
