Your decimal is in the wrong place.
However, assuming the number is 50,000, the answer could be 49987.

Assuming the number is 500,000, the answer could be 499954.

If you want it in fraction form it would be 4/5 but if you wanted it in the percentage it would be there is a 80% chance it will not be a get well card. Work: 4/5 x 2= 8/10 which converted into a percentage would be 80/100, or 80%. Hope this helped!

Help me with Balloon Mortgages?

Ket [755]

I just answered this question. Here's my answer.

Home price is $245,000. There is no down payment mentioned.
I understand 20/4 as amortized over 20 years and balloon payment after 4 years.

Total cost would be = Balloon payment + Total monthly payment

4 years x 12 months = 48 months
Balloon payment = 216,789.79 x 1 mo = 216,789.79
Total monthly payment = 1,727.11 x 47 mos = 81,174.17

<span>Total cost = 216,789.79 + 81,174.17 = 297,963.96</span>

schepotkina [342]

Answer: 160

Step-by-step explanation:

Given : The options to fill science requirement =4

The options to fill diversity requirement =2

The options to fill English requirement =5

The options to fill math requirement = 4

The Fundamental Counting Principle say that the number of total outcomes is equal to the product of the number of ways of all the events occur in the problem.

Using Fundamental Counting Principle, we have the total number of possible outcomes for the given situation :-

$4\times2\times5\times4=160$

Hence, the total number of possible outcomes = 160

A sample of 900900 computer chips revealed that 66f% of the chips fail in the first 10001000 hours of their use. The company's p

Alik [6]

Answer:

No, there is not enough evidence at the 0.02 level to support the manager's claim.

Step-by-step explanation:

We are given that the company's promotional literature states that 68% of the chips fail in the first 1000 hours of their use. Also, a sample of 900 computer chips revealed that 66% of the chips fail in the first 1000 hours of their use.

And the quality control manager wants to test the claim that the actual percentage that fail is different from the stated percentage, i.e;

Null Hypothesis, $H_0$ : p = 0.68 {means that the actual percentage that fail is same as the stated percentage}

Alternate Hypothesis, $H_1$ : p 0.68 {means that the actual percentage that fail is different from the stated percentage}

The test statistics we will use here is;

T.S. = $\frac{\hat p -p}{\sqrt{\frac{\hat p(1- \hat p)}{n} } }$ ~ N(0,1)

where, p = actual percentage of chip fail = 0.68

$\hat p$ = percentage of chip failed in a sample of 900 chips = 0.66

n = sample size = 900

So, Test statistics = $\frac{0.66 -0.68}{\sqrt{\frac{0.66(1- 0.66)}{900} } }$

= -1.267

Now, at 0.02 significance level, the z table gives critical value of -2.3263 to 2.3263. Since our test statistics lie in the range of critical values which means it doesn't lie in the rejection region, so we have sufficient evidence to accept null hypothesis.

Therefore, we conclude that the actual percentage that fail is same as the stated percentage and the manager's claim is not supported.
