Hello,
Area under the curve is 1.
So p(x>5)=1-p(x<5)=1-0.0625=0.9375
Answer A
Answer:
rise over run
Step-by-step explanation:
90=l+l+w+w
90=28+28+w+w
90=56+2w
34=2w
17=w
The width of the playground is 17.
Answer:
y = 4/3
Step-by-step explanation:
The two equations can be added to eliminate x:
(0.1x +0.5y) + (-0.1x -0.2y) + (1.2) +(-0.8)
0.3y = 0.4 . . . . . simplify
Divide by the coefficient of y to find y:
y = 0.4/0.3
y = 4/3
The answer is C. . . . . . . . . . . . .
