Answer:
1 hour and 15 minutes.
Step-by-step explanation:
Since Janet, an experienced shipping clerk, can fill a certain order in 2 hours, while Tom, a new clerk, needs 3 hours to do the same job, to determine how long will it take them to fill the order by working together you must perform the following logical reasoning:
Each of them will do half the work, so in principle, Janet will do her work in 1 hour, while Tom will do it in 1 hour and a half. Now, the remaining half hour that Tom has more than Janet can in turn be divided in two, with which each one will do their work in 15 minutes. Thus, the order will be ready in 1 hour and 15 minutes.
Answer:
.
Step-by-step explanation:
[2(12×17)] + [2(8×12)] + [2(8×17)] = ?
Answer:
True
Step-by-step explanation:
Confidence interval for banking service in a given confidence level can be calculated as M±ME where
- M is the mean banking service in the sample and
- ME is the Margin of Error
margin of error (ME) is calculated using the formula
ME=
where
- t is the corresponding statistic in the given confidence level
- s is the standard deviation of the sample(or of the population if it is known)
t-statistic for 99% confidence level is always bigger than 95% confidence level which makes Margin of Error bigger and thus confidence interval wider.
Area:
The expression for area would be length x width, therefore the expression would be (3x + 1)(2x -7)
Perimeter:
There are many expressions for perimeter. Here are some of them:
Length + width + length + width
2length + 2width
2(length + width)
Let's use the first one, for example. The expression would be (3x + 1) + (2x - 7) + (3x + 1) + (2x -7).
