Suppose that work hours in new zombie are 200 in year 1 and productivity is $8 per hour worked. what is new zombie's real gdp? if work hours increase to 210 in year 2 and productivity rises to $10 per hour, what is new zombie's rate of economic growth?
Final answer:
New Zombie's real GDP in year 1 is $1600 and in year 2 is $2100, resulting in a rate of economic growth of 31.25%.
Explanation:
To calculate the real GDP of New Zombie we must multiply the work hours by the productivity (value produced per hour).
For year 1, the real GDP is calculated as follows:
200 hours * $8 per hour = $1600.
For year 2, we calculate the real GDP as:
210 hours * $10 per hour = $2100.
Now, to find the rate of economic growth from year 1 to year 2, we use the formula:
((GDP in year 2 - GDP in year 1) / GDP in year 1) * 100
= (($2100 - $1600) / $1600) * 100
= 31.25%.
Thus, New Zombie's rate of economic growth is 31.25%.

Step-by-step explanation:
Given : Quadratic form [tex]x^2+16[/tex]
To find : Write the quadratic as a product of factors irreducible over the reals?
Solution :

A store is marking down the price of a television 25 percent from the original price of $250. Which expression can be used to find the marked down price?
A: $250 - (0.25)(250)
B: $250 + (0.25)(250)
C: $250 - (25)(250)
D: $250 + (25)(250)
Answer:
Option A.
Step-by-step explanation:
The original price of a television in a store = $250.00
The store is marking down the price of a television 25 percent from the original price.
25% = [tex]\frac{25}{100}[/tex] = 0.25
The expression can be used to find the marked down price
250 - ( 25% of 250)
= 250 - (0.25)(250)

Shailen is adding three numbers he gets a sum that is an even number between 10 and 20 show two addition equation shailen could have written
Shailen could have written two possible addition equations like 4 + 3 + 8 = 15 or 5 + 7 + 6 = 18. Both of these sum up to an even number between 10 and 20. Order of numbers doesn't matter in addition due to its commutative property.
Explanation:The problem is asking for two possible addition problems that Shailen could be solving if his sum ends up being an even number between 10 and 20. This involves an understanding of the properties of addition and how different number combinations can result in an even sum.
Here are two possible addition equations that meet the conditions:
4 + 3 + 8 = 15
5 + 7 + 6 = 18
In both cases, the sums fall between 10 and 20 and are even. It's worth noting commutativity of addition, which says the order in which numbers are added doesn't change the sum. Hence, you can rearrange the numbers in the addition (e.g., 3 + 4 + 8 or 8 + 4 + 3) and the sum will still remain the same.

The amount of time a bank teller spends with each customer has a population mean = 3.10 minutes and standard deviation = 0.40 minute. if a random sample of 16 customers is selected without replacement from a population of 500 customers,
a. what is the probability that the average time spent per customer will be at least 3 minutes?
b. there is an 85% chance that the sample mean will be below how many minutes?
a. First we solve the finite population correction factor σx from the formula:
σx = [s / sqrt(n)] * sqrt [(N – n) / (N – 1)]
σx = [0.40 / sqrt(16)] * sqrt[(500 – 16) / (500 – 1)]
σx = 0.0985
Then we compute for z score when x ≥ 3 minutes:
z = (x – m) / σx
z = (3 – 3.10) / 0.0985
z = -1.015
From the tables, the probability (p value) using right tailed test is:
P = 0.845 = 84.5%
b. At P = 0.85, the z score is z = 1.04
1.04 = (x – 3.10) / 0.0985
x = 3.20
Hence there is a 85% chance it will be below 3.20 minutes
Final answer:
The probability that the average time spent per customer will be at least 3 minutes is approximately 0.8413. There is an 85% chance that the sample mean will be below approximately 3.359 minutes.
Explanation:
a. To find the probability that the average time spent per customer will be at least 3 minutes, we need to find the probability that the sample mean is greater than or equal to 3 minutes. Since the population standard deviation is known and the sample size is large (n=16), we can use the z-score formula and the standard normal distribution to calculate the probability. The z-score is calculated as follows:
z = (x - µ) / (σ / √n)
where x is the sample mean, µ is the population mean, σ is the population standard deviation, and n is the sample size. Substituting the values into the formula:
z = (3 - 3.10) / (0.40 / √16) = -0.1 / (0.40 / 4) = -0.1 / 0.1 = -1
Looking up the corresponding area to the left of z=-1 in the standard normal distribution table, we find that the probability is approximately 0.1587. Therefore, the probability that the average time spent per customer will be at least 3 minutes is approximately 0.8413.
b. To find the value below which there is an 85% chance that the sample mean will be, we need to find the z-score that corresponds to the cumulative probability of 0.85. Using the standard normal distribution table, we find that the z-score is approximately 1.036. Substituting the values into the z-score formula:
1.036 = (x - 3.10) / (0.40 / √16)
Solving for x:
1.036 * (0.40 / √16) + 3.10 = x
x ≈ 0.259 + 3.10 ≈ 3.359
Therefore, there is an 85% chance that the sample mean will be below approximately 3.359 minutes.

Which recursive formula can be used to represent the sequence 2,5,8,11,14
The recursive formula for the given AP series 2,5,8,11,14 is a₁ = 2 and [tex]a_{n} =a_{n-1} + 3[/tex] so option (D) will be correct.
What is Arithmetic progression?The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression has wider use in mathematics for example sum of natural numbers.
Natural number = 1,2,3,4,5,6,7,8...
Now it has the same difference between any two consecutive terms d =2-1 = 3-2
Given an ap series,
2,5,8,11,14
The first term (a₁) = 2
The nth term of AP can be given as
[tex]a_{n} =a_{n-1} + d[/tex] where d is a common difference.
d = 5 - 2 = 3
So,
[tex]a_{n} =a_{n-1} + 3[/tex]

Construct a 95% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDLcholesterol?
sample mean = x-bar = 4.7
ME = 1.96*15.6/sqrt(43) = 4.663
95% CI: 4.7 - 4.663 < u < 4.7 + 4.663
The 95% confidence interval of (4.5, 9.5) suggests that the true average change in LDL cholesterol after the garlic treatment is likely to fall within this range. However, with a p-value of 0.1494, there isn't enough statistical evidence to conclusively affirm that the garlic treatment significantly reduces LDL cholesterol levels.
Explanation:To construct a 95% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment, you have to be given or calculate the sample mean, the standard error, and the degrees of freedom. These factors depend on the data provided.
In this scenario, using the pre-calculated confidence interval provided, we have it at (4.5, 9.5). This means that we are 95% confident that the true population mean net LDL cholesterol change after garlic treatment is somewhere between a 4.5 unit decrease and a 9.5 unit decrease.
The effectiveness of the garlic treatment cannot be determined solely by this confidence interval, but this range might suggest a possible decrease in LDL cholesterol levels.
However, keep in mind that the p-value signifies the strength of the evidence against the null hypothesis. A p-value of 0.1494, as stated in the problem, means there isn't enough evidence to significantly conclude that the garlic treatment reduced LDL cholesterol at the 5% significance level.
