Use PEMDAS for this.

Also it's a made up question

Answers

PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

First, subtract the numbers in the parentheses, then multiply by 11.

(12 - 9) = (3)

3 x 11 = 33

19 + 11 - 12^2 ÷ 3(33) - 7

Now, just multiply 33 by 3, and then square 12 (12 x 12).

19 + 11 - 144 ÷ 99 - 7

Now, you can divide 144 by 99, this is an infinite number, so..

144 ÷ 99 = 1.455

19 + 11 - 1.455 - 7

Finally add, then subtract.

30 - 1.455 - 7

28.545 - 7

The final answer is 21.545.

Find the value of X, then find AB and DC.
(opposite sides are congruent)
AB= 3x+8
DC= x+12

Answers

Answer:

X=2, AB=14, DC=14

Step-by-step explanation:

3x+8=x+12

Subtract x from both sides

2x+8=12

Subtract 8 from both sides

2x=4

Divide by 2 on the sides

Answer: x=2

Then replace the x's with (2) and multiply

3(2)+8 and (2)+12

Answer:

Both AB and DC are equal to 14.

The color reference provided by the automotive manufacture is 44.21%. Does this known value match the measured value at the 95% confidence level

Answers

Answer:

This known value does not match the measured value at the 95% confidence level.

The 95% confidence interval for value is calculated as 42.92 to 43.78%,

Step-by-step explanation:

The complete question is:

Police have a hit-and-run case and need to identify the brand of red auto paint. The percentage of iron oxide, which gives paint its red color, was determined to be 43.35 ± 0.33% by one method of analysis using five measurements. The color reference provide by the automotive manufacture is 44.21%. What can you conclude about whether the sample matches the reference at a 95% confidence level?

Student's t test is used to compare the two values .

Here n=5

Degrees of freedom =ν= n-1= 5-1=4

The value from t- table for 4 d.f at 95 % confidence interval is 2.776

The test statistic is

x`± t ∝/2(v). S/√n

43.35 ± (2.776)(0.33)/√5

= 43.35 ± 0.43

= 43.78, 42.92

Here the 95% confidence interval for μ calculated is 42.92 to 43.78%, where as color reference provided by the automotive manufacture is 44.21%.

This known value does not match the measured value at the 95% confidence level.

Solution:

The given rate amount is the speed. Speed is the distance divided by the time.

It is mathematically expressed as:

Speed = [tex]\frac{distance}{time}[/tex]

The head of maintenance at XYZ Rent-A-Car believes that the mean number of miles between services is 3408 miles, with a variance of 249,001. If he is correct, what is the probability that the mean of a sample of 36 cars would be less than 3245 miles

Answers

Answer:

The probability that the mean of a sample of 36 cars would be less than 3245 miles

P(X⁻≤3245) = 0.975

Step-by-step explanation:

Step(i):-

The mean number of miles between services

μ= 3408 miles

The Variance of miles between services

σ² = 249,001

σ = √249,001 = 499

Let 'X' be a random variable in a normal distribution

Given sample size 'n' =36

Step(ii):-

[tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]

Z = -163/83.16 = 1.96

The probability that the mean of a sample of 36 cars would be less than 3245 miles

P(X⁻≤3245) = P(Z≤1.96)

= 0.5 + A(1.96)

= 0.5 + 0.4750

= 0.975

Final answer:-

The probability that the mean of a sample of 36 cars would be less than 3245 miles

P(X⁻≤3245) =0.975

The clerks rattle me; the wickets rattle me; the sight of the money rattles me; everything rattles me. The moment I cross the threshold of a bank and attempt to transact business there, I become an irresponsible idiot. I knew this beforehand, but my salary had been raised to fifty dollars a month and I felt that the bank was the only place for it.So I shambled in and looked timidly around at the clerks. I hadan idea that a person about to open an account must needs consult the manager. I went up to a wicket marked "Accountant." The accountant was a tall, cool [scoundrel]. The very sight of him rattled me. My voice was sepulchral."Can I see the manager?" I said, and added solemnly, "alone." I don't know why I said "alone.""Certainly," said the accountant, and fetched him.The manager was a grave, calm man. I held my fifty-six dollars clutched in a crumpled ball in my pocket."Are you the manager?" I said. . . . I didn't doubt it."Yes," he said."Can I see you," I asked, "alone?" I didn't want to say "alone" again, but without it the thing seemed self-evident.The manager looked at me in some alarm. He felt that I had an awful secret to reveal.Come in here," he said, and led the way to a private room. He turned the key in the lock."We are safe from interruption here," he said; "sit down."We both sat down and looked at each other. I found no voice to speak."You are one of Pinkerton's men, I presume," he said.He had gathered from my mysterious manner that I was a detective. I knew what he was thinking, and it made me worse."No, not from Pinkerton's," I said, seeming to imply that I came from a rival agency. "To tell the truth," I went on, as if I had been prompted to lie about it, "I am not a detective at all. I have come to open an account. I intend to keep all my money in this bank."The manager looked relieved but still serious; he concluded now that I was a son of Baron Rothschild or a young Gould."A large account, I suppose," he said."Fairly large," I whispered. "I propose to deposit fifty-six dollars now and fifty dollars a month regularly."The manager got up and opened the door. He called to the accountant."Mr. Montgomery," he said unkindly loud, "this gentleman is opening an account; he will deposit fifty-six dollars. Good morning."I rose. A big iron door stood open at the side of the room."Good morning," I said, and stepped into the safe."Come out," said the manager coldly, and showed me the other way.I went up to the accountant's wicket and poked the ball of money at him with a quick convulsive movement as if I were doing a conjuring trick.My face was ghastly pale."Here," I said, "deposit it." The tone of the words seemed to mean, "Let us do this painful thing while the fit is on us."He took the money and gave it to another clerk. He made me write the sum on a slip and sign my name in a book. I no longer knew what I was doing. The bank swam before my eyes."Is it deposited?" I asked in a hollow, vibrating voice."It is," said the accountant."Then I want to draw a cheque."My idea was to draw out six dollars of it for present use. Someone gave me a chequebook through a wicket, and someone else began telling me how to write it out. The people in the bank had the impression that I was an invalid millionaire. I wrote something on the check and thrust it in at the clerk. He looked at it."What! are you drawing it all out again?" he asked in surprise.Then I realized that I had written fifty-six instead of six. I was too far gone to reason now. I had a feeling that it was impossible to explain the thing. All the clerks had stopped writing to look at me.Reckless with misery, I made a plunge."Yes, the whole thing.""You withdraw your money from the bank?""Every cent of it.""Are you not going to deposit any more?" said the clerk, astonished."Never."An idiot hope struck me that they might think something had insulted me while I was writing the cheque and that I had changed my mind. I made a wretched attempt to look like a man with a fearfully quick temper.The clerk prepared to pay the money."How will you have it?" he said."What?""How will you have it?""Oh" I caught his meaning and answered without even trying to think "in fifties."He gave me a fifty-dollar bill."And the six?" he asked dryly."In sixes," I said.He gave it to me and I rushed out. As the big door swung behind me, I caught the echo of a roar of laughter that went up to the ceiling of the bank. Since then I bank no more. I keep my money in cash in my trousers pocket and my savings in silver dollars in a sock.
