Pedro deposited $35 then withdrew $50 show number line graph

1 answer:

4 0

If you deposit $35, you can imagine drawing a green line (representing the money gained) to the 35 on the number line, which can be seen as moving 35 to the right. Fo withdrawing, imagine drawing a red line back 50 notches on the number line (representing money lost). The net effect that the deposit and withdrawal will have on your account balance is a $35-50=-15$ dollar loss, which can be represented on the number line as a line drawn to the point -15.

An elevator starts at the basement with 8 people (not including the elevator operator) and discharges them all by the time it re

Rus_ich [418]

Answer:

1287

Step-by-step explanation:

Number of people in elevator , n = 8

Number of floors, r = 6

Since they all look alike, arrangement doesn't matter, the we use combination :

(n+r-1 r - 1) = (8+6-1 C 6-1) = 13C5

Recall:

nCr = n! / (n-r)!r!

13C5 = 13! / (13-5)!5!

13C5 = 13*12*11*10*9 / 5*4*3*2*1

= 1287

Jason and Maria are playing a board game in which three dice are tossed to determine a player's move. Find each probability for:

fredd [130]

Tossing a die will have 6 possible outcomes. Those are having sides that are number 1 to 6. The sample space of tossing 3 dice is equal to 6³ which is equal to 216. Now for the calculation of probabilities,

P(two 5s) = (1 x 1 x 5)/216
As we have to have the 5 in the die for two times, then for the 1 time, we can have all other numbers except 5. The answer is 5/216.

P(three 5s) = (1 x 1 x 1)/216 = 1/216

P(one 5 or two 5s) = (1 x 5 x 5)/216 + (1 x 1 x 5)/216 = 5/36
