<u>Answer:</u>

Option (C)

Numbers is arranged in decreasing order is 6.82 , 2π, 55/9, √37

<u>Explanation:</u>

By computing the decimal equivalents of all given values so

the value of 6.82 remains same and

value of 2π is about 6.28 in decimal,

and that of 55/9 is about 6.11 in decimal

and √37 is 6.08 in decimal form.

Since the more the value after decimal point in one's digit, the greater the number will be.

so the order of values is 6.82> 6.28> 6.11> 6.08 so option C is the correct decreasing order of given values.

A fair coin is tossed 3 times in a row. What is the probability that heads appears on only the last toss? A. `1/8` B. `3/8` C. `

expeople1 [14]

Answer:

P(heads appears on only the last toss) = $\frac{1}{8}$

Step-by-step explanation:

A fair coin is tossed 3 times in a row.

When a coin is tossed we get a tail or head T or H

The possible outcomes of 3 coins are

T T T , H H H , T H H, H T H, H H T, H T T , T H T, T T H

So total of 8 possible outcomes

heads appears on only the last toss , first and second toss should be tail

So its T T H. Only one possibility

Probability(any event) = number of outcomes / total outcomes

P(heads appears on only the last toss) = $\frac{1}{8}$

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.
