Answer from: andy6128

In this exercise we have to use the percentage knowledge to calculate the number of employees of the company over the years, in this way we find that this corresponds to:

The percentage of employees with 8 or more years at the company that reported that email is their preferred method of communication is 67,9%. Is D.

They are using the data informed in the text, we have:

210 employees with 8 of more year. Of those, 64 have the email as their preferred method of communication.

So doing the percentage calculation we have that;

$210-64=146\\(146*100)/210=67,19\%$

Answer from: Usman458

The percentage of employees with 8 or more years at the company that reported that email is their preferred method of communication is 30.48%. I suppose there was a small typing mistake in option B.

Step-by-step explanation:

The proportion is the number of desired outcomes divided by the number of total outcomes.

The percentage is the proportion multiplied by 100.

In this question:

210 employees with 8 of more year.

Of those, 64 have the email as their preferred method of communication.

64/210 = 0.3048

0.3048*100 = 30.48%

The percentage of employees with 8 or more years at the company that reported that email is their preferred method of communication is 30.48%. I suppose there was a small typing mistake in option B.

Answer from: Quest

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

$\frac{1}{4}=\frac{x}{5}\\\\x=\frac{4}{5}\\\\x=0.8$

hence, first option 'a' is correct.
