Answer:
3
Step-by-step explanation:
The x value is half of the y value on this chart.
Using the property of inverse,
, we can extend the given table
x f(x) f^(-1)(f(x))
-1 1 -1
2 3 2
3 6 3
5 7 5
7 8 7
Answer:
11/50
Step-by-step explanation:
The frequency numbers for landing on 1, 2, and 3 are:
25, 53, 62.
We add them up to get: 25 + 53 + 62 = 140
Since 250 spins were made, and 140 of them landed on 1, 2, or 3, then
250 - 140 = 110,
so 110 landed on 4 or 5.
We are told the numbers of spins landing on 4 and 5 are equal, so
110/2 = 55,
so the spinner landed 55 times on 4 and 55 times on 5.
relative frequency = 55/250 = 11/50
Numbers that are divisible by 5 will end in 5 or 0
The horizontal distance from the base of the skyscraper out to the ship will be 1140 feet.
<h3>What is trigonometry?</h3>
Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.
Given that:-
- The angle is = 45
- The height of the skyscraper is 1140 feet.
The horizontal distance will be calculated by applying the angle property in the right angle triangle.
tan45 = ( P / B )
B = P / tan45
B = P Since ( tan45 =1 )
B = 1140 feet.
Therefore the horizontal distance from the base of the skyscraper out to the ship will be 1140 feet.
