love history [14]

Answer:

1. JG (Jim gets first prize, George gets second prize)

2. JH (Jim gets first prize, Helen gets second prize)

3. JM (Jim gets first prize, Maggie gets second prize)

4. GH (George gets first prize, Helen gets second prize)

5. GJ (George gets first prize, Jim gets second prize)

6. GM (George gets first prize, Maggie gets second prize)

7. MJ (Maggie gets first prize, Jim gets second prize)

8. MG (Maggie gets first prize, George gets second prize)

9. MH (Maggie gets first prize, Helen gets second prize)

Step-by-step explanation:

The question asks for the list of outcomes in the event "Not A". We are looking for the reverse or negative of Event A.

The above given list is the list of outcomes in the event where Helen DOES NOT get first prize.

PQ= 2x +1 and QR= 5x - 44; find PQ

Lena [83]

2x+1=5x-44 that would be your equation

next start to simplify

subtract 1 from both sides so you are left with 2x=5x-45

then subtract 5x from both sides and you have -3x=-45

then finally divide -3 from -45 to get x=15

9. Gold miners in Alaska have found, on average, 12 ounces of gold per 1000 tons of dirt excavated with a standard deviation of

netineya [11]

Answer:

9.18% probability the miners find more than 16 ounces of gold in the next 1000 tons of dirt excavated

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 12, \sigma = 3$

What is the probability the miners find more than 16 ounces of gold in the next 1000 tons of dirt excavated?

This is 1 subtracted by the pvalue of Z when X = 16. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{16 - 12}{3}$

$Z = 1.33$

$Z = 1.33$ has a pvalue of 0.9082

1 - 0.9082 = 0.0918

9.18% probability the miners find more than 16 ounces of gold in the next 1000 tons of dirt excavated

George still has 40 percent of his book to read. If George has read 180 pages, how many pages does he still have to read? How do

beks73 [17]

Answer: 72

Step-by-step explanation: so you do a line = line method the lines should look like they are fractions.

you do it for the both numbers the percent is always out of 100.

it should look like this

40% ?

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

100% 180

then you cross multiply 40 and 180 and than divide it by 100. your answer should be 72. you later replace the ? with 72

you know this because It is smaller than 180 and its bigger than the number 40.

for a population of 800000 subway riders, the numbers of subway trips taken per rider last january are approximately normally di

vladimir1956 [14]

So, we have
Z=x−μ / σ

Mean would be = 56
30 - 56 = |-26| 4
3 - 56 = |-13|
and
Standard deviation= 13
2 - 1 will give us the approximate area
95/2 - 68/2 = N

95 -68 = 27

27 /2 = 13.5
Hence, the answer would be
800,000 * .135
= 108000
