Answer:
Line A
Step-by-step explanation:
Hello!
Given that the x-values is the time in minutes, and the y-axis is the number of dishes stacked, for every minute, the line should go up by 7.
This means, that the value of y when x is 1 should be 7. The line that follows this rule is Line A. For every minute, 7 dishes are stacked.
The answer is Line A.
The height of the flag is 13 times as tall as the height of a red stripe.
Average is the sum divideided by the number of numbers added together
so avarage of 3 number is 15 means
three numbers represented as x+y+z so
= 15
(x+y+z)/3=15
multiply both sides by 3 to clear fraction
x+y+z=45
45 is the sum of the 3 numbesr
double of that is
45 times 2=90
The least number of points Jared needs to score is 53.
Jared already has an average of 86%. He want to have an overall average of 88. His exam is worth 20% of the total grade. This information can be modelled as:
(0.8 x 86%) + (0.2 x a) = 88%
a = score in the exam.
68.8 + 0.2a = 88%
Combine similar terms
0.2a = 88 - 68.8
0.2a = 19.2
a = 19.2 / 0.2
a = 96%
Jared has to score 96% on the exam.
The second step is to determine which score would give 96%
x / 55 = 96%
x = 55 x 0.96
x = 52.8
x = 53
