Why are the solutions to the proportions StartFraction 50 over x EndFraction = StartFraction 10 over 20 EndFraction and StartFra
asambeis [7]

Answer:

because both result in the equation 10 x = 1,000, which simplifies to x = 100

Step-by-step explanation:

50 / x = 10/20

Cross product

50 * 20 = x * 10

1000 = 10x

x = 1000 / 10

= 100

10/50 = 20/x

Cross product

10 * x = 50 * 20

10x = 1000

x = 1000/10

= 100

The answer is :

because both result in the equation 10 x = 1,000, which simplifies to x = 100

(c) Assume this is a simple random sample of U.S. women. Use the Empirical Method to estimate the probability that a woman has m
ella [17]

Complete Question

The complete question is shown on the first uploaded image

Answer:

p(X> 6 ) = 0.01132 + 0.01672 = 0.0280

           

Step-by-step explanation:

The probability that the US woman would have more than six children is equal to the probability that she would have children that are equal to 7 or that she would that she would have children equal to 8 or more as shown on the table in the question

Now representing this mathematically we have

                     p(X > 6) = p(x =7 ) + p(x = 8 or more)

    From the table the p(x = 7 ) = \frac{523}{46165} = 0.01132

     And the p(x= 8 or more ) = \frac{772}{46165} = 0.01672

Hence  p(X> 6 ) = 0.01132 + 0.01672 = 0.0280

A small business ships specialty homemade candies to anywhere in the world. Past records indicate that the weight of orders is n
FinnZ [79.3K]

Answer with Step-by-step explanation:

Since we have given

n = 16

a) Describe the sampling distribution for the sample mean.

The sampling distribution of the mean is the population's mean from where the items are sampled.

It would be \mu

b. What is the standard error?

s=\dfrac{\sigma}{\sqrt{n}}\\\\s=\dfrac{14}{\sqrt{16}}\\\\s=\dfrac{14}{4}\\\\s=3.5

c. For 90% confidence, what is the margin of error?

Degrees of freedom = v - 1= 16-1 = 15

Using t-table, 1.753 cuts 5% level of significance in each tail.

so, Margin of error would be

1.753\times 3.5\\\\=6.1355

d. Based on the sample results, create the 90% confidence interval and interpret.

So, 90% confidence interval would be

110+6.136\\\\=116.136\\\\and\\\\110-6.136\\\\=103.86

(103.86,116.136)

A big cruise ship dropped anchor off the Caribbean island of Antigua. The heavy anchor dropped into the water at a rate of 2.5 m
4vir4ik [10]

Answer:

1) The anchor was  released from 72.5 meters above the water's surface.

2)The anchor took 29 seconds to reach the water's surface

Step-by-step explanation:

The rate of drop of anchor = 2.5 meters per second

So, total depth covered by anchor after 45 seconds

= 2.5 meters x 45 seconds

= 112.5 meters

But after 45 minutes, the anchor was 40 meters deep.

So, extra distance traveled by anchor = Total distance covered by anchor - depth of water

= 112.5 meters  - 40 meters  =  72.5 meters

Hence, the anchor was  released from 72.5 meters above the water's surface.

Now, speed of anchor = 2.5 m/sec

So, total time taken to cover extra 72. 5 meters = 72. 5 meters / 2.5 m/sec

= 29 seconds

Hence, the anchor took 29 seconds to reach the water's surface.
