Answer:

D) 21

Step-by-step explanation:

r*t=s*u

14*15= 210

so, the easy way to do it is to just multiply all the answer choices by 10 unitil you get 210.

WHY  because r*t = 210 so, 10*x = 210

If you want the break down just set up an equation 10 *( 5x +1 ) = 210

210/10 =21

21-1=20

20/5=4

PLUG IN, 5*4=20

20 +1 = 21

There you go kiddos :)

If 15 actuators have failed today, what is the probability that a) at least 10 are repairable? b) from 3 to 8 are repairable? c)
Ann [662]

The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.

According to the statement

we have given that If 15 actuators have failed and we have to find the probabilities on some conditions.

we know that the formula of probabilities is

probability = possible outcomes / total outcomes

So,

  • at least 10 are repairable = 1 - (10 are not repairable)

at least 10 are repairable = 1 - 10/15

at least 10 are repairable = (15 - 10)/15

at least 10 are repairable = (5)/15

at least 10 are repairable = 1/3

  • from 3 to 8 are repairable = 3/15 *8/15

from 3 to 8 are repairable = 1/5 *8/15

  • exactly 5 are repairable = 5/15

exactly 5 are repairable = 1/3

These are the probabilities of the given conditions.

So, The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.

How much is a 40% discount off of $74.99
pychu [463]

Answer:

\frac{40}{100}  \times  \frac{7499}{100}

\frac{2}{5}  \times  \frac{7499}{100}

\frac{1}{5}  \times  \frac{7499}{50}

\frac{7499}{250}

7499/250= 29.996

74.99-29.996= $44.994
