Answer:
Yes, more than half are being used. (292 out of 546 used)
Step-by-step explanation:
The first part of this problem is to determine the total amount of seats on the plane so we can determine what half of the seats would be.
1st class has 14 seats.
Business-class has 64 seats.
And the 4 economy classes have 117 each, meaning 117 * 4 = 468
So the total amount of seats are 14 + 64 + 468 = 546
So half that amount would be 273.
Now we can determine the number of seats being used.
1st class has (6/7) * 14 = 12 seats used
Buisness-class has (7/16) * 64 = 28 seats being used
Economy has 4 * (7/13) * 117 = 4 * 63 = 252 seats being used
So the total amount of used seats would be 12 + 28 + 252 = 292.
Note that 292 is greater than 273, so there is indeed more than half the seats on the plane being used.
Cheers.
Answer: D. f(x)=-34x+320
The line of best fit for the scatter plot shown would have a value of positive 320 when x=0 and it’s a drecreasing slope so it will need to have a negative x value.
f(x)=-34x+320
Answer:
b
Step-by-step explanation:
because I learned this like 4 years ago
1c = 16t = x(
)
1c = 16t = 16 X 3
1c = 16t = 48
