Aliun [14]

Answer:

Only the firsts and fourth choices (\frac{2}{3}(x+9)=-18 and \frac{2}{3}x+6=-18)

Step-by-step explanation:

Turn the equation into words:

"A number plus 9"

(x+9)

"Multiplied by \frac{2}{3}"

\frac{2}{3} (x+9)

"Is equals to -18"

\frac{2}{3}(x+9)=-18

Andrei [34K]

Probability is 0

Step-by-step explanation:

The key information is that the data is normally distributed.

In a normal distribution, each individual value of hours has a probability equals to zero. It is a continuos distribution which is centered in the mean value, and where the expected value is the average.

As the distribution it is centered in the mean value, and it is symmetrical, then the probabilty of a bulb lasting more than the mean value is 0.5, and the probabilty of lasting less than avergare is 0.5 as well, but each individual valu is 0

Calculate the 5th term of the sequence which has this explicit formula: an=3/2n(2n+5), n=1,2,...
Zielflug [23.3K]

Answer:

D. 9 ÷ 2

Step-by-step explanation:

For getting the nth value of the sequence we simply put the value of n in a formula.

In the given sequence for finding the 5th term we simply put n = 5 in given explicit formula:

We have a_{n} = \frac{3}{2n}(2n+5)

Putting n = 5

a_{5} = \frac{3}{2\times5}(2\times5+5)

⇒ a_{5} = \frac{3}{10}(15)

⇒ a_{5} = \frac{9}{2}

Thus, option (D) is correct.
