Answer:
Yes.
Step-by-step explanation:
If we wrote the equation down
7=4-(-3)
Then, we do keep, change, change
7 = 4+3
Y = 7
The equation is true, so that means the points are.
Because they have the same measurements and are equal
Using the law of sins:
side a / sin (angle A) = side b / sin(Angle B)
Side a is opposite angle A, so from the picture we know side a = 50, angle A is 58 degrees and angle B is 48 degrees.
replace those values in the formula we get:
50 / sin(58) = b/ sin(48)
so now we can cross multiply the 2 fractions to get:
50 * sin(48) = b*sin(58)
to get b by itself, divide both sides by sin(58) to get:
b = (50*sin(48)) / sin(58)
b = 43.82
You may need to round the answer as needed.
Answer:
£672
Step-by-step explanation:
so you add 12 to 100 which is 112
then do 112 divided by 100 and multiplied by 600 on a scientific calculator.
you will get £672 I'm not sure but try it anyways.
Answer:
Zero
Step-by-step explanation:
Failure Rate = 1 in every 5 hours
It is important to consider the time that it takes for 2 components to fail
* Standard deviation is not given for failure rate hence it is assumed to be zero.
What is the probability that 12 hours will elapse before 2 components fail?
In other words, what is the probability that it takes 12 hours for 2 components to fail?
This probability is = 0
This is because the time it takes for 2 components to fail is 10 hours.
No adjustment can be made for this time, as there is no stipulated standard deviation.
