Answer:
Marcus score is 13.7, the mean is 12.89, and the standard deviation is 1.95, so I’ll do ( 13.7 – 12.89)/ 1.95, Since Marcus' z-score is 0.415. The area to the left of the z-score is 65.9% so therefore Marcus did scored better than 65.9% of the students. So Marcus needs to score 98% better of all the other students in order for him to receive an actual certificate.

Answer:
the angle is 245°
Step-by-step explanation:
that is a pentagon, (a shape with 5 sides)
we know 4 of the angles in the pentagon
the sum of those 4 angles is
58°+100°+112°+25°=295°
to find a shapes total amount of °, the equation is (n-2)x180°
(5-2)x180°
=540°
540°-295°=245°
x=245°
Answer:
79 m
Step-by-step explanation:
We know that
Perimeter of rectangle = 2(l + b)
=> 288 = 2(l + 65)
=> 288/2 = l + 65
=> 144 = l + 65
=> 144 - 65 = l
=> 79 = l
Hence,
Length of rectangle is 79 m
