A student ran out of time on a multiple choice exam and randomly guessed the answers for two problems. Each problem had 5 answer choices - a, b, c, d, e- and only one correct answer. What is the probability that she answered neither of the problems correctly? Do not round your answer. (If necessary, consult a list of formulas.)

Answers

Answer:

there is a 64% chance that the student got both problems wrong

a 32% chance that they got only 1 correct

and a 4% chance that they got both correct

Step-by-step explanation:

There are 25 total possible combinations of answers, with 8 possible combinations where the student would get 1 answer right, and 1 combination where the student would get both answers correct.

$25-9=16$

$(16)/(25) =(x)/(100)$

$(64)/(100)$

$64$ %

$(8)/(25) =(y)/(100)$

$(32)/(100)$

$32$ %

$(1)/(25) =(z)/(100)$

$(4)/(100)$

$4$ %

Hey there!

ANSWER: $p=25$

EXPLANATION:

$0.4p-5=0.08p+3$

To solve this inequality, we will need to subtract 0.08p from both sides of the inequality.

$0.4p-5-0.08p=0.08p+3-0.08p\n0.32p-5=3$

Now we have to add both sides by 5.

$0.32p-5+5=3+5\n0.32p=8$

In our last step, we will have to divide both sides by 0.32.

$(0.32p)/(0.32) =(8)/(0.32)\n25\n\text{25 is your answer.}$

Hope this helps!

Answer:

p=25

Step-by-step explanation:

Look at the answer above.

An investigative bureau uses a laboratory method to match the lead in a bullet found at a crime scene with unexpended lead cartridges found in the possession of a suspect. The value of this evidence depends on the chance of a false positive positive that is the probability that the bureau finds a match given that the lead at the crime scene and the lead in the possession of the suspect are actually from two differant melts or sources. To estimate the false positive rate the bureau collected 1851 bullets that the agency was confident all came from differant melts. The using its established ctireria the bureau examined every possible pair of bullets and found 658 matches. Use this info to to compute the chance of a false positive.

Answers

Answer:

Step-by-step explanation:

Given that, we have 1851 bullets that we KNOW are NOT MATCHES of one another. One by one they examine two bullets at a time.

So, there are 1851 bullets but each time we choose 2.

We have, N choose K = N! / K! (N-k)!

Here, N = 1851 and K = 2

Therefore, 1851 choose 2 = 1851! / 2! (1851-2)!

= 1851! / 2! * 1849!

= 1712175 Possible Combinations

Out of these 653 are false positive.

The chance of getting false positive is = 658 / 1712175

= 0.000384

= 0.0384 %

Therefore, The correct option is

The chance of false positive is 0.0384% Because this probability is sufficiently small (< or = 1%) There is high confidence in the agency's forensic evidence.

3.A train can travel 360 miles in 4 hours. How much time will it take
travelling 585 miles?

Answers

Answer:

6.5 hours

Step-by-step explanation:

We can write a ratio to solve

360 miles 585 miles

---------------- = ------------

4 hours x hours

Using cross products

360 * x = 4* 585

360 x = 2340

Divide each side by 360

x = 2340/360

x =6.5
