Answer:
680 students
Step-by-step explanation:
The 68 - 95 - 99.7 rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean, 95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.
Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:
number of people that like MATH 123 = 68% of the population
number of people that like MATH 123 = 0.68 * 1000
number of people that like MATH 123 = 680 students
The answer would be D. y=75x+300 because if you multiply 75 and 20 you would get 1500 and subtract 1800 for how much was paid and 1500 for the result of multiplying 75 and 20
Answer is D. y=75x+300
Actually Welcome to the concept of expo functions.
f(x) = -8(2)^x - 12 ,
for f(0) ,here substitute x = 0
so we get as ,
==> f(0) = -8(2)^0 -12
==> f(0) = -8-12
==> f(0) = -20
hence, f(0) = -20
Answer:
69
Step-by-step explanation:
If every 175th person gets free admission, that means
175th
175 * 2 = 350th
175 * 3 = 525th
person gets free admission and so on...
This basically means <em><u>"how many 175s are there is 6742 (for first day) and 5487 (for 2nd day)?"</u></em>
<em><u /></em>
We would need to divide and see the WHOLE number, not the fractional(decimal) amount remaining. So
<u>1st Day:</u>
6742/175 = 38.53
This means 38 people will get free admission
<u>2nd Day:</u>
5487/175 = 31.35
This means 31 people will get free admission
In the 2 days, total of 38 + 31 = 69 people will get free admission
