Answer:
third number = 4,
equation of y, y = 5x - 11
equation of n, n = 4x
equation of x, n + x + y =19
Step-by-step explanation:
so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19
10x = 30
x = 3.
Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11
15 - 11
4 = third number
Answer:
B. 4
Step-by-step explanation:
cos(45°) = x/4√2
√2/2 = x/4√2
x = 4√2•√2/2
x = 4
The corollary of the statement tends that its not the Poisson experiment.
<h3>What is Poisson experment</h3>
It is a statistical approach to follow properties that The experiment outcomes that can be opted as successes or failures. That gives a outcome in a specified region is known in average number of successes i.e. (μ).
The probability of a given task is not a Poisson experiment because the mean number of successful outcomes in its domain neither constant nor given.
