Answer:
47
Step-by-step explanation:
follow Pemdas order of operations.
8 + (9 + 23) − 9 + 8 × 6 ÷ 3 =
8 + (32) - 9 + 8 x 6 ÷ 3
8 + (32) - 9 + 16
add and subtract the rest and u get 47
Answer:
gradient=change in y/change in x
=y2-y1/x2-x1
=-8-(-16)/-10-(-8)
=8/-2
=-4
Answer:
Top graph on the left
Step-by-step explanation:
f(x) =2(3)^x
Let x = 1
f(1) =2(3)^1
= 2 *3 = 6
(1,6)
1/3

1/5
1/6
1/7
1/8
1/9
1/10
And so on..
Hope this helped!
Answer:
32.33% probability of having at least 3 erros in an hour.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
The mean number of errors is 2 per hour.
This means that
(a) What is the probability of having at least 3 errors in an hour?
Either you have 2 or less errors in an hour, or we have at least 3 errors. The sum of the probabilities of these events is decimal 1. So
We want
So
In which
32.33% probability of having at least 3 erros in an hour.
