Answer:
The x-value is between 2 and 3, and the y-value is between -4 and -5
Step-by-step explanation:
The plot of the equations:
y = 1/4x - 5 (red)
y = -1/2x - 3 (blue)
is shown in the figure attached.
The solution to the system is found at the intersection point. In this case, the solution is x = 2.667 and y = -4.333
Answer: i think this is it
the answer would be 3
Step-by-step explanation:
It says something like this: Multiply each value by the frequency of that value: 1*7, 2*1, etc. I'll let you write down the rest.
Divide by the sum of the frequencies, 7 + 1
Step-by-step explanation:
Hi
2n³ + 4n² - 7 + (-n³ - 8n - 2) = 2n³ - n³ + 4n² - 8n - 7 - 2
n³ + 4n² - 8n - 9
Answer: n³ + 4n² - 8n - 9
Answer:
(i). 0.03981
(ii).0.0048
Step-by-step explanation:
The probability density function of Poisson distribution is:
Consider <em>X</em> is a number of typos error on a single page of a book and <em>X</em> follows the Poisson distribution with 
(i) Exactly two typos:
(ii) Two or more typos:
