A=2piR
so 144pi=2piR
solve and you get R=72
so D= 144 ft
Answer:
a. 0.93 b. 0.06 c. 0.05
Step-by-step explanation:
Probability is commonly known as the chance of success of a particular event. The probability of failure of the event can also be estimated.
(a) Probability of not having type 2 defect is: 
= 1 - 0.07 = 0.93
(b) Probability of having type 1 and 2 defects is: 
(c) probability pf having both type 1 and type 2 defects but not type 3 defect is:
Answer:
Y=2x+7
Step-by-step explanation:
To find the gradient of the line u have to subtract the y intercepts and the x intercepts
11--9/2--8=20/10=2
Y-11/x-2=2
Y-11=2(x-2)
Y-11=2x-4
Y=2x-4+11
Y=2x+7

Answer:
3 grams
Step-by-step explanation:
on the left side there is 3 circles and every circle is 3 grams, so there is 9 grams plus 6 squares for 2 grams its 12 . 9+12 =21 and two triangles with x mass
on the right side there is 2 circles , 2×3 = 6, and 3 squares, 3×2 = 6. 6+6=12 +5x
both sides are equal so we have
21+2x=12+5x
21-12=5x-2x
9=3x
x=3
