(Correct)
3. 25% = 0.25 (Correct)
(Error)!

Answer:</h2>
Option: D is the correct answer.
The probability is: 0.50
<h2>
Step-by-step explanation:</h2>
Weight/Calories 1000-1500 1500-2000 2000-2500 Total
120 lb. 90 80 10 180
145 lb. 35 143 25 203
165 lb. 15 27 75 117
Total 140 250 110 500
We are asked to find the probability that a person consumes 1500-2000 calories in a day.
Total number of people who were surveyed=500
Total number of people who consume 1500-2000 calories in a day are:250
Hence, Probability is:
250/500=1/2=0.50
the ansewr is x=3 and y=0
Given:
The fees for a day student are $600 a term.
The fees for a boarding student are $1200 a term.
The school needs at least $720000 a term.
To show:
That the given information can be written as
.
Solution:
Let x be the number of day students and y be the number of boarding students.
The fees for a day student are
a term.
So, the fees for
day students are
a term.
The fees for a boarding student are
a term.
The fees for
boarding student are
a term.
Total fees for
day students and
boarding student is:

The school needs at least $720000 a term. It means, total fees must be greater than or equal to $720000.


Divide both sides by 600.


Hence proved.
