11) 1/6

There are 12 total cards. Out of those cards, there are 2 letter S's.

2/12 = 1/6

12) 5/12

There are 12 total cards. Out of those cards, there are 3 T's and 2 E's. Because this is an 'or' probability, we will add the probability of drawing a T and E together.

3/12 + 2/12 = 5/12

13) Likelu

There are 12 total cards. Out of those cards, there are 5 vowels.

5/12 = 41.7%

The probability of this event occurring is less than 50%, but there is still a good chance of it occurring, so the probability is likely.

Hope this helps! :)

The distribution of the amount of money spent by students on textbooks in a semester is approximately normal in shape with a mea
zheka24 [161]

Answer:

$301 - $397

Step-by-step explanation:

Using the Empirical rule

1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

2)95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

3)99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

From the above question,

Mean = 349 , standard deviation = 24.

Confidence interval = 95%

Using 2)95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

μ – 2σ

= 349 - 2(24)

= 349 - 48

= 301

μ + 2σ

349 + 2(24)

= 349 + 48

= 397

Therefore, according to the standard deviation rule, approximately 95% of the students spent between $301 and $397 on textbooks in a semester.

8_murik_8 [283]
19.30 - ( p / 100 )*19.32 = 14.01 ;
19.30( 1 - p/100 ) = 14.01 ;
1 - p/100 = 14.01 / 19.30
1 - p / 100 = 0.72 ;
p/100 = 1 - 72 / 100 ;
p/100 = 28 / 100 ;
p = 28 ;
The percent discount is 28% ;
