Answer 1

Answer:

Answer:

z = -3.73

Probability = P(z<-3.73) = 9.48761E.05

Step-by-step explanation:

Detailed explanation is given in the attached document.

Answer 2

Answer:

The probability that the project will take more than 30 days to complete can be found using the NORMSDIST() function in Excel, and it depends on the z-score associated with the project's completion time distribution.

To find the probability that a project will take more than 30 days to complete using the normal distribution, you'll need to follow these steps:

1. Calculate the z-score for 30 days using the formula:

Z = (X - μ) / σ

Where:

- X is the value you're interested in (30 days in this case).

- μ is the mean completion time (expected completion time).

- σ is the standard deviation of completion times.

2. Once you have the z-score, use Excel's NORMSDIST() function to find the probability associated with that z-score.

Here's a hypothetical example of how to do this:

Let's say the expected completion time (mean) for the project is 25 days, and you have a standard deviation (σ) of 5 days. Now, calculate the z-score:

Z = (30 - 25) / 5

Z = 1

Now, use Excel's NORMSDIST() function to find the probability associated with a z-score of 1:

`=1 - NORMSDIST(1)`

This formula will give you the probability that the project will take more than 30 days to complete.

Make sure to replace the mean (25) and standard deviation (5) in the formula with the actual values from your project data. Additionally, round the z-score to two decimal places and the final answer to four decimal places, as requested in your question.

Jacob the dog eats dry food that contains 324kcal/cup. Jacob eats 3.5 cups a day. The food contains 3.6 g of fat in 100 kcals of energy. what is his daily fat intake?the food contains 25.6 IU of Vitamin D3 in 100 kcals of energy. what is his daily Vitamin D inake?

Answers

Answer:

His daily fat intake is 40.824g.

His daily Vitamin D intake is 290.304 IU.

Step-by-step explanation:

The first step to solve this problem is finding the daily kcal intake of the dogs.

Each cup has 324 kcal, and he eats 3.5cups a day. So:

1 cup - 324 kcals

3.5 cups - x kcals

$x = 324*3.5$

$x = 1134$ kcals.

His daily intake is of 1134 kcals.

The food contains 3.6 g of fat in 100 kcals of energy. what is his daily fat intake?

There are 3.6g of fat in 100 kcals of energy. How many g of fat are there in 1134 kcals?

3.6g - 100 kcals

xg - 1134 kcal

$100x = 1134*3.6$

$x = (1134*3.6)/(100)$

$x = 11.34*3.6$

$x = 40.824$ g

His daily fat intake is 40.824g.

The food contains 25.6 IU of Vitamin D3 in 100 kcals of energy. what is his daily Vitamin D inake?

Similar logic as above.

25.6IU - 100 kcals

x IU - 1134 kcal

$100x = 1134*25.6$

$x = (1134*25.6)/(100)$

$x = 11.34*25.6$

$x = 290.304$ IU

His daily Vitamin D intake is 290.304 IU.

Answer with Step-by-step explanation:

We are given that

$f(x)=-sin x$

$[0,\infty]$ ]

Average value of the function is given gy

$f_(avg)=(1)/(b-a)\int_(a)^(b)f(x)dx=(1)/(\pi-0)\int_(0)^(\pi)-sinx dx$

$f_(avg)=(1)/(\pi)[cosx]^(\pi)_(0)$

Using the formula

$\int sin xdx=-cos x$

$f_(avg)=(1)/(\pi)(cos\pi-cos0)$

$f_(avg)=(1)/(\pi)(-1-1)=-(2)/(\pi)$

$f(x)=f_(avg)$

$-sinx=-(2)/(\pi)$

$sinx=(2)/(\pi)$

$x=sin^(-1)((2)/(\pi))=0.69radian$

The Ericsson method is one of several methods claimed to increase the likelihood of a baby girl. In a clinical trial, results could be analyzed with a formal hypothesis test with the alternative hypothesis of pgreater than0.5,which corresponds to the claim that the method increases the likelihood of having a girl, so that the proportion of girls is greater than 0.5. If you have an interest in establishing the success of the method, which of the following P-values would you prefer: 0.999, 0.5, 0.95, 0.05, 0.01, 0.001? Why?

Answers

Answer:

0.001

Step-by-step explanation:

Here, the aim is to support the null hypothesis, Ha. Where Ha: p > 0.5. Which means we are to reject null hypothesis H0. Where H0: p = 0.5.

The higher the pvalue, the higher the evidence of success. We know If the pvalue is less than level of significance, the null hypothesis H0 is rejected.

Hence the smallest possible value 0.001 is preferred as the pvalue because it corresponds to the sample evidence that most strongly supports the alternative hypothesis that the method is effective

Find the total amount of interest on a savings account if the principal is $9400 and the bank gives a rate of 6% compounded quarterly for the next 6 years.

Answers

Answer:

4037.3264$

Step-by-step explanation:

Total amount of money after 6 years:

A = P x (1 + rate)^time

= 9400 x ( 1 + (6/100)/4)^(6 x 4)

= 13437.3264$

=> Total amount of interest after 6 years:

I = A - P = 13437.3264 - 9400 = 4037.3264$
