First we would find the area of the entire thing,
A=1/2(base)(height)
so A = 1/2(5)(12) = 30 mm^2
next we find the area of the smaller triangle,
A = 1/2(4)(3) = 6 mm^2
Then we subtract the area of the smaller triangle from the area of the larger one
30-6 = 24 mm^2
Answer:
Step-by-step explanation:
Given that transitor has a 2% defective rate, need to calculate the probability that the 10th transistor produced is the first with a defect.
The probability function is p(x=k) = (1-p)^(n-1) * p
p = (1-defective rate)^(n-1) * defective rate; n=10
p = (1-0.02)^9 * 0.02 = 0.98^9 * 0.02 = 0.01666
Answer:
855
Step-by-step explanation:
90x9.5=855
Answer:
820
Step-by-step explanation:
If you use order of operations, you can find that 3x0 and 1x400x100x456x0 is just 0 so you just have to add 2x2 and 34x24. Which is 820
order of operations is
GEMDAS
Grouping symbols
exponents
multiplication and division (these don't have to be in order)
Addition and Subtraction (again, these don't have to be in order)
The hypotenuse of the triangle is 2x
the one opposite of 30 is x
and the one opposite of 60 is sqrt(3)*x
since x=11, the side is 11
