Answer:
6
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
6+2+4+2+2+7+5+6+3+3=40
40/10=4
Therefore the mean is 4
Current average = (80 + 93 + 63 + 83 + 83) / 5
= 402 / 5
= 80.4
79 x 6
= 474
what he needs to score on the next test = 474 - 402
= 72
{reassurance = (80 + 93 + 63 + 83 + 83 + 72) / 6
= 474 / 6
= 79}
if the line is parallel is has the same slope so it will be a horizontal line
it must pass thru the point (7,5)
y =5
Answer:
