Answer:
the mean number of days absent is 0.72 days ( since 0.72 is not an integer, we can say that is the average number of days absent is close to 1 day)
Step-by-step explanation:
given a random variable X= number of days absent , the mean is calculated as:
mean = ∑ x * p(x) , for all the x possible
where x = number of days absent and p(x) the probability of "x" number of days absent
therefore
mean = 0 * 0.60 + 1 * 0.20 + 2*0.12 + 3*0.04 + 4* 0.04 + 5* 0.00 = 0.72 days
Y = mx + b
slope(m) = 6
(-3,5)...x = -3 and y = 5
now we sub and find b, the y int
5 = 6(-3) + b
5 = -18 + b
5 + 18 = b
23 = b
so ur equation is : y = 6x + 23
Answer:
D
Step-by-step explanation:
Recall that a⟌b means b/a. So, we want to find the expression: 20⟌4 and 4 ÷ 20. By examining, we see that D has those two expressions.
So, the answer is
and we're done!
Omg I thought this was an actual internet scam looking at it
Answer:
483,000,000
Step-by-step explanation:
483,000,000 is already rounded to the nearest million.
48<u>3</u>,000,000
/\
The three underlined is the millions place, as there is no numbers after it this is already rounded.
Have a nice day!
