Answer:

8, 20, 32, 44, 56
arithmetic

Step-by-step explanation:

The words "common difference" tell you this is an arithmetic sequence. A geometric sequence will have a common ratio between terms.

The common difference is added to each term to get the next.

first term: 8 -- given

second term: first term + common difference = 8 + 12 = 20

third term: 20 +12 = 32

fourth term: 32 +12 = 44

fifth term: 44 +12 = 56

The first 5 terms of this arithmetic sequence are 8, 20, 32, 44, 56.

sveta [45]

Answer:

13.53% probability that no earthquakes with a magnitude of 6.5 or greater strike the San Francisco Bay Area in the next 40 years

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

$e = 2.71828$ is the Euler number

$\mu$ is the mean in the given time interval.

According to geologists, the San Francisco Bay Area experiences five earthquakes with a magnitude of 6.5 or greater every 100 years.

One earthquake each 100/5 = 20 years.

What is the probability that no earthquakes with a magnitude of 6.5 or greater strike the San Francisco Bay Area in the next 40 years?

40 years, so $\mu = 40/20 = 2$

This probability is P(X = 0).

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-2}*2^{0}}{(0)!} = 0.1353$

13.53% probability that no earthquakes with a magnitude of 6.5 or greater strike the San Francisco Bay Area in the next 40 years

A lawnmower costs $284, and the six-year extended warranty on the lawnmower costs 17% as much as the lawnmower itself. What is t

Veseljchak [2.6K]

Answer:

The correct answer option is c. $8.05.

Step-by-step explanation:

We are given that a lawnmower costs $284, and the six-year extended warranty on the lawnmower costs 17% as much as the lawnmower itself.

We are to find its effective price per year of the extended warranty.

So, the amount of six year warranty = $\frac { 17 } { 100 } \times 284$ = $48.28

Price of warranty per year = $\frac { 48.28 } { 6 }$ = $8.05

kupik [55]

Answer:

6.04%

Find the percentage of 182 is 11. 11/182 = about 0.0604

Percent = Decimal * 100

0.0604 * 100 = 6.04
