95% of the students will score between 400 and 600, because you use a bell shaped graph and normal distribution to put the variables in the bottom. The graph i attached should help. So the answer is 95% of the students will score between 400 and 600. Hope this helped, and by the way I am a girl, not a poly whatever guy like that person said lol.
Answer:
Area of background without flower bed = 575 feet²
Step-by-step explanation:
Given:
Length of rectangle ground = 35 feet
Width of rectangle ground = 20 feet
Height of triangle bed = 10 feet
Base of triangle bed = 25 feet
Find:
Area of background without flower bed
Computation;
Area of background without flower bed = Area of rectangle - Area of triangle
Area of background without flower bed = [l x b] - (1/2)(b)(h)
Area of background without flower bed = [35 x 20] - (1/2)(25)(10)
Area of background without flower bed = 700 - 125
Area of background without flower bed = 575 feet²
The area is 288 units squared, or D. 72 times 4 equals 288.
