Answer:
Step-by-step explanation:
Let the height of the street lamp be x
Opposite angle is 40° and the shadow, the hypotenuse of the formed triangle is 20 ft.
- sin 40° = x/20
- x = 20sin 40°
- x ≈ 12.86 ft
Hello!
We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.
To solve, we just multiply the two probabilities.
=0.2125≈21.3
Therefore, we have about a 21.3% chance of this event occurring.
I hope this helps!
Answer:

Step-by-step explanation:
Given that,
A sequence 352,345,338.
First term = 352
Common difference = 345-352 = -7
We need to find the 37th term of the sequence.
The nth term of an AP is given by :

So, the 37th term of the sequence is 100.
×= 10 and ×= -14
Find x by simplifying both sides of the equation then isolate the variable.
