Answer:
B. 12 units
Step-by-step explanation:
Law of sines,. a/sinA = b/sinB = c/sinC
25/sin44 = c/sin88. Angle C is 88° because the three angles of any triangle add to 180°
now a little Algebra gives us that
25(sin88)/sin44 =35.966 so B is our answer
3.556 is the correct answer
Answer:
The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.
Step-by-step explanation:
In this problem we have a normal ditribution with mean of 4.0 in and standard deviation of 1.5 in.
The proportion of the trees that are expected to have diameters greater than 5 inches is equal to the probability of having a tree greater than 5 inches.
We can calculate the z value for x=5 in and then look up in a standard normal distribution table the probability of z.

The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.
The vertex is (3,3) and the axis is 3
