So basically you form little trapaziods to fin =d the area. It's been a long time since I took calculus so Imma have to improvise
Area or trapaziod = area of rectangle + area of triangle so you get
2*1+(3-2)*1/2+3*1+(6-3)*1/2+6*1+(11-6)*1/2=15.5
Well if you had 900 and shows loss it would be c
Answer:
It's A and B
Step-by-step explanation:
Since she took 75% off of her commute time, she has 25% left. 25% as a decimal is 0.25 and 0.25 as a decimal is 1/4.
Also, since it says choose two answers, C and D are not equal to each other.
Using the Pythagorean theorem we can solve for x.
x^2 + 6^2 = 10^2
Simplify:
x^2 + 36 = 100
Subtract 36 from both sides:
x^2 = 64
x = √64
x = 8
Randomly assigned group. the art class isn't random and only consists of a select type of people--it is not a representative sample; maybe more left handed people enjoy art than do right handed people! therefore, even though the randomly assigned group is smaller, it is the better estimate.
