Answer:
50 ft
Step-by-step explanation:
The side lengths in a 30-60-90 triangle have the ratios 1 : √3 : 2. The longest side is 2 times the length of the shortest side.
In this geometry, that means the length of the escalator is 2 times its height, so is ...
x = 2(25 ft)
x = 50 ft . . . . . distance a person travels
Answer:
D. 2
Step-by-step explanation:
soh cah toa rule
sine equals opposite over hypotenuse,
cosine equals adjacent over hypotenuse, and
tangent equals opposite over adjacent
csc is 1/sin which is hypotenuse over opposite
if csc is -√5/2 then
hypotenuse is -√5
opposite is 2
3rd quadrant on a graph is bottom left
both x and y values are negative
hypotenuse means its a triangle
pythagorean theorem
a^2 + b^2 = c^2
a^2 + 2^2 = (-√5)^2
a^2 + 4 = 5
a = 1 = adjacent
tangent equals opposite over adjacent
tan is 2 / 1 which is 2
third quadrant means it's still positive
because tan is positive in quadrant 3

Answer = p=12-4 -12=17=18+19
p-q
p=12
Answer:
a. yes
b = 0.0563
c. 0.1460
d. 0.7560
Step-by-step explanation:
a. Yes. n = 10 identical trials with two possible outcomes on each with p = 0.25.
b. p(x= 0) = 10!/(0!*10!)* .250* .7510= 1 * 1 * 0.0563 = 0.0563.
c. p(x= 4) = 10!/(4!*6!)* .254* .756= 210 * .0039 * 0.1780 = 0.1460
d. p(x= 1) = 10!/(1!*9!)* .251* .759= 10 * .25 * 0.0751 = 0.1877
p(x≥ 2) =1 - p(x< 2) = 1 – (0.0563 + 0.1877) =0 .7560
