Answer:
PS=5.4
Step-by-step explanation:
The centroid divides each median in the ratio 2:1
If U is the centroid, then

We use ratio to obtain;

Cross multiply;

Expand;

Group similar terms;


x=1
PS=PU+US
PS=3.6+1+0.8
PS=3.6+1+0.8
PS=5.4
Answer:
It is not a factor
Step-by-step explanation:
It is because p(x)=-12 at x=3
2·(2 + 9 + 2/SIN(30°)) = 30
Answer:
1497 - 202
Step-by-step explanation:
The question is saying that the Las Vegas trip was longer so we know to put that first in the expression
we can also tell that the question is asking us for the difference (aka subtraction) between the two trip by the key words <em>how much longer</em>
and then it tells us that we are finding the difference between Las Vegas and Cheyenne so we know to use those two numbers
that is how we come up with the expression 1497 - 202
Answer:
11.8 ;
0.1036360
Step-by-step explanation:
Mean births per day, μ = number of births per year / number of days in a year ;
4310 / 365 = 11. 8 births per day
From poisson distribution :
P(x) = (μ^x * e^-μ) ÷ x!
P(x = 13) = (11.8^13 * e^-11.8) ÷ 13!
P(x = 13) = 6.453438E8 / 13!
P(x = 13) = 0.1036360
