Answer:
if sinx=3/5=P/H
using pythogoras thoeren find B
B²= H²-P²
B²= 25-9
B=4
Tanx = P/B= 3/4
3.
n(S)= 6
n(O) = 3 {1,3,5)
P(O) = n(O)/n(s)= 3/6=1/2
Step-by-step explanation:
Answer:
y = 35x+200
Step-by-step explanation:
The $200 is a constant, and the $35 PER credit hour makes it dependent on x.
So I added all of the numbers of tourists together, I got 30 tourists. Then I saw that the number of tourists that visisted the museum but not the zoo was 5. I divided 5 by 30 and got that there was a 16% chance that a randomly selected tourist would of visited the museum but NOT the zoo.
Hope this helps!

Answer:
a. 0.5
Step-by-step explanation:
We know that X follows normal distribution with
mean=75
standard deviation=8
P(0<Z<∞)
The area under the normal curve is 1 and the (0<Z<∞) =0.5 and (-∞<Z<0) =0.5
So, P(0<Z<∞)=0.5
Hence the P(X ≥ 75)=0.5
Answer:
a = 16.13 ft²
Step-by-step explanation:
Triangle
a = (1/2)bh
a = (1/2)6 * 4
a = 12
Semicircle
a = (1/2)πr²
a = (1/2)(3.14)(3²)
a = 14.13
Combined figure
a = 12 + 14.13
a = 16.13 ft²
