A group of scouts helped rangers clear a trail after an ice storm. They cleared tree branches from 2 5/6 miles of trail the firs

Gwar [14]

Answer:

The remaining number of miles to trail will be $3\frac{3}{4}$ miles.

Step-by-step explanation:

A group of scouts cleared tree branches from $2\frac{5}{6}$ i.e. $\frac{17}{6}$ miles of trail the first day. On the second day, they cleared $3\frac{1}{4}$ i.e. $\frac{13}{4}$ miles of trail.

Therefore, in two days they have cleared $(\frac{17}{6} + \frac{13}{4}) = \frac{17 \times 2 + 13 \times 3}{12} = 5$ miles.

If the length of the trail is $8\frac{3}{4}$ i.e. $\frac{35}{4}$ miles, then the remaining number of miles to trail will be $\frac{35}{4} - 5 = \frac{15}{4} = 3\frac{3}{4}$ miles. (Answer)

A dice game lets you roll 2 6 sided disc and find the sum of the numbers. A 12 wins 100 dollars, 10 or 11 wins 50 dollars, a 2 w

Advocard [28]

Answer:

Step-by-step explanation:

A two 6 sided die is rolled

Sample space would be (1,1)...(1,6)....(6,1)....(6,6)

Let x be the sum obtained

X can take values as 2 or 3 ....12

P(x=12) = P(6,6) =1/36

P(x=10 or 11) = P{(5,5)(5,6) (6,5) (4,6)(6,4)}=5/36

P(2) =P(1,1) = 1/36

For other outcomes no payment

Thus we can list this as

Sum 2 3 4 5 6 7 8 9 10 or 11 12

Prob 1/36 5/36 1/36

Gain 3 0 0 0 0 0 0 0 50 100

E(gain) 3/36 0 0 0 0 0 0 0 250/36 100/36

E(gain) = total= 353/36

Cost of game = 6

E(outcome) = E(gain -6) = E(gain)-6 = 353/36 -6

= 3.806

What is w - (-7) = 2 with the work

kramer

Ok since you are solving for w, you remove the parentheses first w-(-7) it would convert to a +7, so the equation would be w+7=2 subtract the 7,on both sides to isolate the w. And w=-5.
