A department store is holding a drawing to give free shopping sprees to two lucky customers. There are 17 customers who have ent
mixer [17]

Answer: Our required probability is 0.044.

Step-by-step explanation:

Since we have given that

Number of customers who have entered the drawing = 17

Number of customers live in the town of Gaston = 5

Number of customers live in Pike = 4

Number of customers live in Wells = 8

The first customer will be selected and then second customer will be selected from the remaining .

Probability of getting first customers are Pike residents = \dfrac{4}{17}

Probability of getting second customers are Pike residents = \dfrac{3}{16}

So, the probability that both customers selected are Pike residents are

\dfrac{4}{17}\times \dfrac{3}{16}\\\\=0.044

Hence, our required probability is 0.044.

For the first four days of a five day vacation, the mean temperature was 80 degrees. What must the temperature be on the fifth d
V125BC [204]

Answer:

The 5th day must be 90

Step-by-step explanation:

The first 4 days averaged out to 80

You can find their total just by multiplying by 4. That won't tell you the exact values, but it will tell you their total when you add the 4 of them together.

80*4 = 320

Now you need to add another day into the mix. Call it x

320 + x

Now there are 5 days, not 4, and the new total is 82.

(320 + x) / 5 = 82          Multiply both sides by 5

5*(320 + x) / 5 = 82 *5

320 + x = 410                 Subtract 320

-320        -320

x = 90

The length of human pregnancies from conception to birth varies according to a distribution that is approximately normal with me
iragen [17]

Answer:

a) 229 and 305 days

b) 229 days or less

c) 305 days or more

Step-by-step explanation:

The Empirical Rule(68-95-99.7 rule) states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 267

Standard deviation = 19

(a) Between what values do the lengths of the middle 95% of all pregnancies fall?_____________and___________days

By the Empirical rule, 95% of all pregnancies fall within 2 standard deviations of the mean.

So

267 - 2*19 = 229 days

to

267 + 2*19 = 305 days

(b) How short are the shortest 2.5% of all pregnancies?______days or less

95% of all pregnancies fall within 2 standard deviations of the mean. The other 5% are more than 2 standard deviations from the mean. Since the distribution is symmetric, 2.5% is more than 2 standard deviations below the mean(shortest 2.5%) and 2.5% is more than 2 standard deviations above the mean(longest 2.5%). So

267 - 2*19 = 229 days

c) How long do the longest 2.5% of pregnancies last?________days or more

Explanation in b)

267 + 2*19 = 305 days
