c=62.8 a=314
Step-by-step explanation:
to find the circumfrence all you have to do is 2πr
and for area its πr²
Answer: y=6x-5
Step-by-step explanation:
Since we know the slope, we can plug it into the slope-intercept equation. We can plug in the given point to find the y-intercept.
y=6x+b
1=6(1)+b
1=6+b
b=-5
Now that we know the y-intercept, we can complete the equation.
y=6x-5
This is all middle school stuff.
First do the powers. 3 power plus -5 power equals to -2 power.
2 x 5 is 10. So, it's 10 to the power of -2.
Answer:
Step-by-step explanation:
a.
let A= number 5
B=number >3
P(A)=1/6 {5}
P(B)=3/6 {4,5,6}
p(A∩B)=1/6 {5}
P(AUB)=P(A)+P(B)-P(A∩B)=1/6+3/6-1/6=3/6=1/2
b.
let event C=number<5
D=even number
C=[1,2,3,4}
D={2,4,6}
C∩D={2,4}
P(C)=4/6
P(D)=3/6
P(C∩D)=2/6
P(C∪D)=P(C)+P(D)-P(C∩D)=4/6+3/6-2/6=5/6
c.
let event E=number 2
F= an odd number.
E={2}
F={1,3,5}
E∩F={}
P(E)=1/6
P(F)=3/6
P(E∩F)=0
P(E∪F)=P(E)+P(F)-P(E∩F)=1/6+3/6-0=4/6=2/3
Answer:
Multiply each term in the 2nd equation by 2
Step-by-step explanation:
This will allow him to eliminate the 2y
