You didn’t link any attachments or anything but since it rotated 90* clockwise it’s going to be upside down or right side up from the previous image.

You are playing a game where you draw a card from a standard deck, and you will win $13 if you draw a face card,
marissa [1.9K]

Answer:

Step-by-step explanation:

win

There are 3 face cards / suit. Every suit contains a Jack, Queen, and king.

There are 4 suits so the number of face cards is 3*4 =  12

There is 1 ace / suit

There are 4 suits so the number of aces is 1 * 4 = 4

The gain from the face cards = 12 * 13 = 156

The gain from the aces = 4 * 3 =               12

Total gain = 168

Losses

Any other card costs you $5

How many cards is that? 52 - 16 = 36

Each one costs 5 dollars

Total loss = 5 * 36 = 180

So each time you play the game, you can expect to lose 180 - 68 = 12 dollars. You should walk away quickly from this one.

You select a sample of 50 scores from a population of 2,000 scores. You compute the range and standard deviation on the sample o
nalin [4]

Answer:

The measure of dispersion which is likely to vary most between your first and second samples is the range.

Step-by-step explanation:

The range and standard deviation of a data are measures of dispersion, i.e. they measure the degree to which the data is dispersed.

The formula to compute the range is:

Range=X_{max}-X_{min}

The formula to compute the sample standard deviation is:

s=\sqrt{\frac{1}{n-1}\sum (X-\bar X)^{2} }

The sample size is: <em>n</em> = 50.

  • As the sample size is large (n = 50 > 30) the sample standard deviation (s) can be used to approximate the population standard deviation (σ). Thus, whatever the sample values be both the standard deviations can be used to approximate the population standard deviation. Hence, it can be said that both the sample standard deviations are approximately equal.
  • Whereas the range of the two samples are very likely to vary since it is based on the minimum and maximum value of the data. For both the samples the minimum and maximum value may be differ. Thus providing different range values.

Thus, the measure of dispersion which is likely to vary most between your first and second samples is the range.

during a sale a shirt was marked down from 70 to 56 what was the percent decrease in the price of the shirt
melomori [17]

20%

70 x n%= 56

n% = 70 x 56

n = 0.8 x 100

n = 80

the percent decrease = 100 - 80

= 20 %
