It's Rational since its a Fraction
Answer:
Probability that a 20- cubic foot block of wood has at most 1 knot P (X<=1) = 0.5918
Step-by-step explanation:
Average rate of knot= 1.4
Wavelength = 1.4
Geometric probability is given by:
P(X= K) = wavelength ^k × e^-wavelegth
P(X=0) = (1.4^0 × e^-1.4)/0!
P(X=0) = 1 × 0.2466 = 0.2466
P(X=1) = 1.4^1 × e^-1.4
P(X=1)= 1.4×0.2466= 0.3452
P(X<=1)= P(X=0) + P(X=1)
P(X<=1) = 0.2466 + 0.3452 = 0.5918
Answer:
(0, 6)

(2, 7)
Step-by-step explanation:
Just implement x and solve for y.
CENTROID is the term used to describe the point where the three medians of a triangle intersect.
Centroid is the center of gravity of the triangle. It is one of the triangle's point of concurrency. Aside from "center of gravity", it is also known as "center of mass" and "barycenter".
Centroids are always inside the triangle. Since, the centroid is where three medians intersect, each median divides the triangle into two smaller triangles of equal area. The centroid is exactly two-thirds the way along each median.
Other types of triangle centers aside from Centroids are:
1) incenter
2) circumcenter
3) orthocenter
Answer:
enlargement
Step-by-step explanation:
Actual picture is smaller than the scaled one
Scaling is used to enlarge the actual picture
So the answer is enlargement
