Answer:
b
Step-by-step explanation:
Answer:
A. B = 5
Step-by-step explanation:
Joe:
J(b) = 14b + 7
Will:
W(b) = 7b + 42
Where,
b = number of hamburgers cooked
J(b) and W(b) = amount of time each cook takes in minutes respectively
At what value of b will their cooking time be equivalent?
Equate both functions
Joe = Will
14b + 7 = 7b + 42
Collect like terms
14b - 7b = 42 - 7
7b = 35
Divide both sides by 7
b = 35 / 7
= 5
b = 5
The answer is
A. B = 5

Answer: C 4
Step-by-step explanation:
Use the formula: distance = rate x time
We can say that train 1 travels a distance of x, and train 2 travels a distance of 700 - x
The rate of train 1 is 75 mph, and the rate of train 2 is 100 mph
The time traveled for the two trains will be the same. We can represent that with the variable t.
We have the following equation for train 1:
x = 75t
For train 2, we have this equation:
700 - x = 100t
Use the Substitution Method by replacing x in the equation for train 2 with the value 75t.
700 - 75t = 100t
700 = 175t
700/175 = 4 hours.
It will take 4 hours for the two trains to meet.
Answer:
Convenience sampling.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Quota sampling.
6. Convenience (opportunity) sampling.
Convenience sample can be defined as a sampling technique in which the representatives to be used are easily accessible. For example, a researcher using a social media poll such as Twitter polls.
In this scenario, Catherine Chao, Director of Marketing Research, chooses thirty-six of her closest friends to participate in the testing of a new toothpaste package. Thus, Catherine's sample is a convenience sampling.
