Answer:

1. The relative frequency of heads is (A) reasonably close to 40%.

2. Mr. Clark's claim about the theoretical probability is likely to be (A) True.

3. This means that the theoretical probability of tails is most likely 0.6 for this coin.

Dear Math Helper,
valentina_108 [34]

Answer:

n = 98, that is, she scored at the 98th percentile.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

She scored 38, so X = 38

Test scores are normally distributed with a mean of 25 and a standard deviation of 6.4.

This means that \mu = 25, \sigma = 6.4

Find the percentile:

We have to find the pvalue of Z. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{38 - 25}{6.4}

Z = 2.03

Z = 2.03 has a pvalue of 0.98(rounding to two decimal places).

So n = 98, that is, she scored at the 98th percentile.

0.01 written as a percent then round to the nearest tenth of a percent
Aleks [24]

Answer and step-by-step explanation:

To write it as percent, multiply it with 100, we get:

0.01 * 100 = 1%

Nearest tenth of a percent would be 10%, 20%, 30%, etc.

So as we can see 1% is nearest to 10% so we round it up to 10%

Hope this helped :3

What are the next three terms in the sequence 5, 14, 23, 32, ...? 43, 54, 65 45, 54, 63 41, 50, 59 47, 56, 65
nikitadnepr [17]
Take a careful look at 5, 14, 23, 32.  Each new term is equal to the previous term PLUS 9.  Thus, 9 is the "common difference."

Next 3 terms?

32 plus 9 is 41
41 plus 9 is 50
50 plus 9 is 59
59 plus 9 is 68.
and so on

So the "next 3 terms in the seq. 5, 14, 23, 32 are 41, 50, 59.
