the base of the triangle would be 20 +5 = 25 feet
the angle of elevation is 30 degrees
multiply tan(30) by 25 = 14.433
rounded to nearest foot = 14 feet
Y intercept on 5 and move down 3 then right 1
Call the point of attachment at the top of the building point T. (Angle T = 25°) The angle N = 180° -32° -25° = 123°. The Law of Sines tells you the relationship ...
... TM/sin(N) = MN/sin(T)
... MN = TM·sin(T)/sin(N) = (200 ft)·sin(25°)/sin(123°)
... MN ≈ 100.8 ft
The answer is A. If you add all the numbers up at the top you will see the top of the box length is 52. Multiply 52 with 38 and you get 1976. The to find the surface area of the little boxes you do 10x16 which is 160. Since there are two little boxes you add them to be 220. Then add 220 with 1976 to get the final answer.
Answer:
e
Step-by-step explanation:
mean = 16 ounces
standard deviation = 0.2×16 ounces = 3.2 ounces
standard deviation of sample mean = 3.2/√64 = 3.2/8 =0.4
z value of 15 is (15-16)/0.4 = -1/0.4 = -2.5, using z-table corresponding p value = 0.00621
P(average <15) =0.00621
so answer is (e)
