A
function is an operation you perform to a number or expression. For example, my function could be "add five to the input". Now the
input is what you have before you use the function; it's what you put into the function. For example, my input could be the number 7. If I put it through my function of adding five, I get 7+5=12. 12 is the
output; what you have after you put it through the function. Hope this helped.
Chart relating to the question is attached below.
Answer:
349 students
Step-by-step explanation:
Based on the chart given, we can obtain the experimental probability or proportion for the travel plan of 75 students :
Proportion who would be traveling by car :
Number traveling By car / number of samples
p(car) = 23 / 75 = 0.30666
If total number of students = 1138
Using the proportion obtained from the sample, the number of students who would be traveling by car from the population would be :
= 0.30666 * 1138
= 348.98 students
= 349 students
Answer:
3 or 3/1 (the 1 is the denominator)
Step-by-step explanation:
the shape got 3 times bigger. let me know
Let the triangle be abc with equal sides ab,bc and ca
then perimeter = 3 ab = 12a + 18b
ab = = 4a + 6b ( each side will have this length)
Now since qr is a mid segment it will be = half length of ab
So qr = 2a + 3b Answer
