The number of rookie cards in a variety pack of baseball cards is normally distributed with a mean of 3 cards and the standard d
Sergio039 [100]

Answer:

z = \frac{2-3}{\frac{1}{\sqrt{10}}}=-3.163

z = \frac{4-3}{\frac{1}{\sqrt{10}}}=3.163

P(-3.163

P(-3.163

So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10

Step-by-step explanation:

Let X the random variable that represent the number of rookie cards of a population, and for this case we know the distribution for X is given by:

X \sim N(3,1)  

Where \mu=3 and \sigma=1

We select a sample size of n = 10 variety packs and we want to find this probability:

P(2

We can use the z score formula given by:

z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}

If we apply this formula to our probability we got this:

We can find the z score for 2 and 4 and we got:

z = \frac{2-3}{\frac{1}{\sqrt{10}}}=-3.163

z = \frac{4-3}{\frac{1}{\sqrt{10}}}=3.163

So we can find the probability with this difference

P(-3.163

And using the normal standard distirbution or excel we got:

P(-3.163

So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10

“The following are the distances (in miles) to the nearest airport for 16 families. 10, 11, 14, 15, 16, 18, 20, 27, 27, 30, 31,
slava [35]

We can construct a box-and-whisker plot to represent a five statistical summary. To do this plot, we need first to find:

1. Minimum of the data.

2. First quartile.

3. Median.

4. Third quartile.

5. Maximum of the data.

To do this:

1. We first need to order the data from least to greatest. It has already been done.

Then, we have that the minimum is 10. We also know that the maximum is 42. We have these two points to graph in the plot.

Median

2. Now we need to find the first quartile, the median, and the third quartile.

We can find the median first. The data in ascending order is:

10, 11, 14, 15, 16, 18, 20, 27, 27, 30, 31, 33, 33, 37, 38, 42

The median is the value for which 50 percent of the data is below it, and 50 percent of the data is above this value. We have here, an even number of data (16 values). Then, we have that the median is:

a. We have that the median is 27 because we have an even number of data, we have two central values:

10, 11, 14, 15, 16, 18, 20, 27, 27, 30, 31, 33, 33, 37, 38, 42

We need to sum these numbers and then divide them by 2. Then, we have:

(27 + 27)/2 = 27.

First Quartile

3. The first quartile is a value for which 25% of the values are below it, and 75% of the values are above it. We can proceed in a similar way (as we do for the median) to find the first quartile having into account the first eight numbers:

10, 11, 14, 15, 16, 18, 20, 27

Because we have an even number of values, we take the two central numbers, and then we need to find an average between them:

(15 + 16)/2 = 15.5

Third Quartile

In this case, we can do the same to find the first quartile, but because we need to find the third quartile, we need to take the last eight values:

27, 30, 31, 33, 33, 37, 38, 42

Then, the third quartile is:

(33 + 33)/2 = 33

Now, we have these five statistics:

Minimum = 10

First Quartile = 15.5

Median = 27

Third Quartile = 33

Maximum = 42

Now, we can plot these values as follows:

1. We can plot in a line the given numbers.

2. We need to graph these five numbers in this line.

3. The box starts in the First Quartile, and finish in the Third Quartile.

4. We draw the median inside the box.

5. Minimum and maximum will be outside this box.

Then, this graph is:

And this is the box and whisker plot for these data.

What are the interest cost and the total amount due on a six-month loan of $1,800 at 14.4 percent simple annual interest
kiruha [24]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Principal (P)= $1,800

Number of periods (t)= 6 months

Monthly interest rate (r)= 0.144/12= 0.012

<u>To calculate the interest to be paid and the total amount due, we need to use the following formula:</u>

<u></u>

I= P*r*t

I= 1,800*6*0.012

I= $129.6

Total amount= $1,929.6

Describe a real life multiplication situation for which an estimate make sense
Wittaler [7]
So, let's say that I have 3 bills: a 50 dollar bill, a 100 dollar bill and 1 dollar bill.

I need to buy 9 pens for my friends, and each of the pens costs 4.34 dollars.

I want to know if I can just take the 50 dollar bill, since I'm not too comfortable to carry the 100 dollar bill the whole day.

A quick estiate tells me that 10 times 5 is 50, and since both numbers are less, then in fact, 50 dollar bill will be enough!
