Answer:
Step-by-step explanation:
we can simply find the relative frequency as foloows:
We are given are No piercings, One or two piercings, and More than two piercings. The relative frequency with no piercings is 188/361 = 0.521, the relative frequency for one or two piercings is 82/361 = 0.227. The total has to add to 361, so there are 361−188−82 = 91 students with more than two piercings, and the relative frequency is 91/361 = 0.252. the below table describes each.
It would be (8)(4$) because 7.9 rounds up to eight and 3.89 also rounds up to 4
Answer:
x=133
Step-by-step explanation:
the missing angle plus are supplementary. the missing angle is 47 as a triangle must be 180 degrees.
therefore 180=x+47

Answer: 24 feet</h3>
========================================================
Explanation:
Refer to the diagram below. We have a right triangle with known horizontal leg 18, and unknown vertical leg x. The hypotenuse is 30.
Let a = x, b = 18, c = 30.
Apply the Pythagorean theorem to solve for x
a^2 + b^2 = c^2
x^2 + 18^2 = 30^2
x^2 + 324 = 900
x^2 = 900-324
x^2 = 576
x = sqrt(576)
x = 24
The top of the ladder reaches 24 feet high.
