Answer:
9.7
Step-by-step explanation:
Here is the correct question with picture attached: Lines DE and AB intersect at point C
What is the value of x?
(2x+2)
°
(16x+3)°
Now, finding the value of x.
∠ACE+∠ECB= 180° (∵ They form a straight line angle)
∴
Opeing the parethesis.
⇒
⇒
subtracting 5 on both side.
⇒
cross multiplying the number
⇒x=
∴x= 9.7
I know two ways that we can use in this problem, it depends on your knowledge in your math class.
The first way is using the combinatorial formula, and probability:
P = possibles outcomes from the event/ all outcomes from the experiment
Using combinatoria P = (2C2*4C1)/(6C3)
2C2 is the possibles ways to get two defectives and we calculate that:
2C2=2!/(2!*(2-2)!)=1
Then, 4C1 is the possibles ways to get 1 no defective (remember you need only 3 test and you expect 2 are defective from the question), calculating:
4C1=4!/(1!*(4-1)!)=4
And 6C3 represents the all possible ways to get 3 calculators (no matter if they defective or not), calculating:
6C3=6!/(3!*(6-3)!)=20
Apply p formula:
<span>P = (1*4)/20 = 1/5 = 0.2</span> in percertage 20%
The another way to calculate this problem is using the tree diagram or multiplication rule:
P=(2/6)*(1/5)*(4/4)=1/15 (here you are saying the order of computer, first and second defective and the last one no defective)
P=(2/6)*(4/5)*(1/4)=1/15 ( the second is no defective, and the others are defective)
P=(4/6)*(2/5)*(1/4)=1/15 (the first one is no defective and the others are defective)
Finally add the three result above, and get the answer:
<span>P=1/15+1/15+1/15 = 3/15 = 1/5 = </span>0.2
Answer: I THINK A function f (x) is called increasing in an interval [a,b] when f' (x) > 0 in the interval (a,b). That is, in that interval, with increasing the value of x the value of f (x) increases. Let f (x) be the function which is shown in the given diagram.
Step-by-step explanation:
70 because 55+55 = 110 and a triangle is 180 so 180-110= 70 and X is opposite to the angle we worked out as the missing one
