Answer:
The correct answer should be the third option(175.9 cubic units)
Step-by-step explanation:
let's say pi is 3.14-
ok, ill do my work to find volume
4 x 4 x 3.14 =
50.24
50.24 x 7 =
351.68
351.68 ÷ 2 =
175.84
175.9 and 175.84 are super close so that should be the correct answer!
Using P(A∪B) = P(A) + P (B) - P(A∩B)
If we apply this in the question
Then P(S∪T) = P(S) + P(T) - P (S∩T)
= 6/11 + 1/10 - P (S∩T)
= 71/110 - P (S∩T)
But events S and T are mutually exclusive events therefore,
P(S∩T) = 0,
Hence P(S∪T) = 71/110

Step-by-step explanation:
Step-by-step explanation:
g(x) = ax²+bx+c
g(x)=−3x²−6x+5
a = -3, b= -6, c = 5
since a <0 , the function has only maximum value.
=> g'(x) = 0
-6x -6 = 0
-6x = 6
x = -1
the maximum value => g(-1) =
-3(-1)²-6(-1)+5 = -3+6+5 = 9
the domain : {x | x € Real numbers}
the range : {y| y ≤ 9, y € Real numbers}
the function is increasing for x < -1
the function is decreasing for x > -1
Answer:
assuming the three options are no solutions, one solution and all real numbers, i would say the final option. i forgot what the proper wording is thoough
