2(x+2) = 60
x+2 = 30
x = 28
The correct answer is C
Answer:
The chance of getting exactly 3 hits is = 0.20
Step-by-step explanation:
P.S - The exact question is -
As given,
F(x) = 0 , x < 1
0.30 , 1 ≤ x < 2
0.56 , 2 ≤ x < 3
0.76 , 3 ≤ x < 4
0.9 , 4 ≤ x < 5
1 , 5 ≤ x
Now,
f(x) = 0.30 , x = 1
0.56 - 0.30 = 0.26 , x = 2
0.76 - 0.56 = 0.20 , x=3
0.9 - 0.76 = 0.14 , x = 4
1 - 0.9 = 0.1 , x = 5
0, otherwise
Now,
The chance of getting exactly 3 hits is = f(x = 3) = 0.20
Your answer is 6 centimeters because you would have to subtract 3 from 9. Hence, your answer is 6.

4x + 11 = 8x + 1
11 = 4x + 1
10 = 4x
/4 /4
2.5 = x
X = 2.5
The approximate distance between points (-7,2) and (11,-5) is
=√[11-(-7)]²+[(-5-2)]²
=√(18)²+(-7)²
=√324+49
=√373
