Step-by-step explanation:
7 choose 2 or
=7! / (7-2)!
=7*6*5*4*3*2*1 / 5*4*3*2*1
=7*6
=42
The first one and the 6,7,8th one all go to the right reasoning is for the positives section

5 2/3 gallons of fuel ... 2 hour trip
x gallons of fuel = ? ... 1 hour
If you would like to know how many gallons were used each hour, you can calculate this using the following steps:
5 2/3 * 1 = 2 * x
17/3 = 2 * x /2
x = 17/6 = 2 5/6 gallons of fuel
The correct result would be 2 5/6 gallons of fuel.
The answer is M= 2 so the answer is B
Answer:
a) WCK, WTM, WTK, BCM, BCK, BTM, BTK.
b) 1/4
Step-by-step explanation:
a)
For this answer we just need to write all possibilities of sandwiches, so we can use the options given to create all the sandwiches, besides the one given:
(WCM given), WCK, WTM, WTK, BCM, BCK, BTM, BTK.
b)
From the letter a), we have 8 possible options. From these options, we have 2 that have turkey and ketchup (WTK and BTK), so the probability is the number of options we want over the total number of options:
P = 2/8 = 1/4
