The left-hand "tail" of the standard normal curve can be defined as the part of it that lies at least two standard deviations to

the left of the mean.
According to the Empirical Rule, approximately what percentage of the area under the whole curve is in the left-hand tail? Round your answer to the nearest tenth.

Roughly 95% of the data lies within 2 standard deviations of the mean. 

So (100% - 95%)/2 = 2.5% of the data lies within each tail.

This means roughly 2.5% of the data is in the left hand tail.

Answer:

2.5%

Step-by-step explanation:

The Empirical Rule states that 95% of the values lies between two standard deviations to the left of the mean and two standard deviations to the right of the mean. 50% of the values lies on the left side respect to the mean; so, 95%/2 = 47.5% of the values lies in the region formed two standard deviations to the left of the mean. In consequence, 50% - 47.5% = 2.5% of the values lies on the left-hand "tail" of the standard normal curve.

Use the equation an = a1 + (n – 1)d to write a rule for the arithmetic sequence 32, 41, 50, . …
jarptica [38.1K]

Answer: an = 9n + 23

Step-by-step explanation:

The formula for determining the nth term of an arithmetic sequence is expressed as

an = a1 + (n - 1)d

Where

a1 represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = 32

d = 9

Therefore, the equation or rule for the given arithmetic sequence would be

an = 32 + (n - 1)9

Expanding the brackets, it becomes

an = 32 + 9n - 9

an = 9n + 32 - 9

an = 9n + 23

There are 4 prime numbers
amid [387]

Answer:

No

Step-by-step explanation:

As you go to larger numbers, there are more possibilities of factors for them.

For example, the internal from 20 to 30 contains only two prime numbers (23 and 29) and the interval from 90 to 100 contains only one prime (97).

However, the number of prime numbers in an interval varies. There are four prime numbers between 100 and 110 (101, 103, 107, 109).
