Step-by-step explanation:
So the answer for 33+45+78 is 156.
If you want to check that, you can use inverse operations, so subtract.
156-78=78. (Check 78)
78-45=33 (Check 45 and 33)
Well, now it's checked because we used all the factors of the equation!
Answer:
-5/6
Step-by-step explanation:
3(1/6+2/9)+(-2)
3(7/18)+(-2) working what is in parenthesis.
7/6-2 reduced the numbers ( 3 and 18) with greatest common divisor . which is 3
-5/6 calculate the difference
Answer:
A.) The probability that the missile is not detected by any of n sets = (1-0.9)^n = 0.1^n.
Where it's opposite will be that the missile is detected by atleast 1 of the sets. Which will be equals to 1-(0.1)^n.
B.) 0.999= 1-(0.1)^n
Here n=3
For, 0.999999=1-(0.1)^n
n=6.
C.) If n=5
5C4*(0.9)^4*(0.1)^1= 0.32805
Answer:
$0.13 to produce each box.
Step-by-step explanation:
S= ph+2b
p= 12.5+2.5+12.5+2.5=30
h=25
b= 12.5x2.5=31.25
S= (30)(25) +2 (31.25)
S= 
812.5 x 0.00016= 0.13
≈ 0.00020
