Six​ stand-up comics,​ A, B,​ C, D,​ E, and​ F, are to perform on a single evening at a comedy club. The order of performance is
kiruha [24]

Answer:

a) 1/6

b) 1/36

c) 1/720

d) 1/3

Step-by-step explanation:

a) Any of the six comics can perform in the fourth place, so there is one chance in six that Comic F is the one that performs fourth.

P(F=4th)=1/6

b) In this case, we have two conditions. Both are independent of each other, so the probability of both happening is the product of the probabilities of each happening individually:

P(D=4th \&B=2nd)=P(D=4th)\cdot P(B=2nd)=(1/6)\cdot(1/6)=1/36

c) This combination is one in all possible orders of perform. The amount of combinations of orders is n!=6!=720 possible combinations. So the probability of this specific order is:

P(F, D, B, A, C, E)=1/720

d) In this case, of the six possible comics performing in the last place, we calculate the probability of 2 of them being in that place. So the probability is:

P(C=6th\,or\, E=6th)=2/6=1/3

Clare volunteers at a local library during the summer. Her work includes putting labels on 750 books. How many minutes will she
Lubov Fominskaja [6]

Answer:

75 minutes

Step-by-step explanation:

Assuming that Clare will not take a break throughout the session

10 books=1 minute

750 books= x minutes

Cross multiplying to find the value of x

10x books=750 books minutes

Making x the subject

x=750 books minutes/(10 books)

x=75 minutes

This translates to 1 hours and 15 minutes

Therefore, Clare will require 75 minutes

What is 7 2/10 as a decimal
Dmitry_Shevchenko [17]
When changing fractions into decimals the whole number goes before the period and the fraction goes after.The denominator of the fraction will tell you whether or not you need to put any zeros before the numerator. If the denominator is 10 zeros are not needed.The end result is 7.2 and can be read as seven tenths.

If an object is projected upward with an initial velocity of 126 ft per​ sec, its height h after t seconds is h= -16^2+126t. Fin
Phoenix [80]
All you would have to do is plug in 5 for t since that is the time; then you would see that the height of the object after 5 seconds is 886 ft. Hope this helped!
