Answer
Find out the how much weight does she need to remove from her suitcase.
To prove
Let us assume that the weight Clara's need to remove from her suitcase be x.
As given
the airline's weight limit for suitcases is 50 pounds
Than the equation becomes
x = 8.25 pounds.
Therefore the weight Clara's need to remove from her suitcase be 8.25 pounds.
As 1 pounds = 16 ounces
Convert 8.25 pounds into ounces.
x = 8.25 × 16
x = 132 ounces
Therefore the weight Clara's need to remove from her suitcase be 132 ounces.
Answer: She needed to remove 8 pounds 4 ounces from her suitcase.
Step-by-step explanation:
Since we have given that
Weight of Clara's suitcase is given by
But the weight limit for suitcases = 50 pounds
So, She needs to remove from her suitcase is given by
Hence, She needed to remove 8 pounds 4 ounces from her suitcase.

Answer:
Probability that Adam and Ella will be selected:
Step-by-step explanation:
Probabilities
The probability of a random event E to occur is a real number between 0 and 1, both inclusive, where 0 indicates an impossible event and 1 a sure event. There are many techniques to compute probabilities depending on the particular situation and distribution.
This question will be solved by simple calculations and logic, given its simplicity. We know the middle school chess club has 5 members: Adam, Bradley, Carol, Dave, and Ella. Two of them are going to be selected at random to participate in the county chess tournament. We can calculate the number of different ways it can be done without any restriction. It's called the sample space.
The sample space of this event is the combination of 5 members regardless of their position. If {a,b,c,d,e} are the five members, then the possible combinations are {ab,ac,ad,ae,bc,bd,be,cd,ce,de}. Notice that there are only 10 possibilities because the combination ab is the same as ba since it's the same team for the tournament.
We can see there is only one combination of two specific letters out of 10. If a=Adam and e=Ella, only one combination is ae, the other 9 don't include both members, so the probability is
Answer:
1) 0.5 or 50%.
2) Order does not matter: 3,003 combinations.
Order matters: 360,360 permutations.
Step-by-step explanation:
1) The probability of drawing either a purple or a blue chip is the sum of both individual probabilities:
the probability that a blue or a purple chip will be drawn is 0.5 or 50%.
2)
a) Choose 5 items from a total of 15 items when order does not matter:
b) Choose 5 items from a total of 15 items when order matters:
