Answer:
Step-by-step explanation:
total number of students=21
students play neither sport=6
students who play at least one sport=21-6=15
Let play basketball=X
and play baseball=Y
n(XUY)=n(X)+n(Y)-n(X∩Y)
15=11+6-n(X∩Y)
n(X∩Y)=17-15=2
reqd. probability=2/21
[multiply the first equation by -2]
[-2x - 10y = 4]
[add like terms between the equations]
[-5y = 10]
[y = -2]
[x = 8]
(8, -2)
Answer:
27
Good one! Didn't trip me up tho
The problem gives you X, so replace X witht he given vaule and solve for y:
y = -0.1x^2 + 4X
X = 40
y = -0.1(40)^2 +4(40)
y = -0.1(1600) + 160
y = -160 + 160
y = 0
<span>In the question "Complete the following equation using <, >, or =. 100% ___ 1" The correct answer is 100% = 1. A percentage is a number or ratio expressed as a fraction of 100. To convert a given percentage to its equivalent number, we divide the given percent by 100. Therefore, 100% = 100 / 100 = 1.</span>
