At a show, there are 19 adults, 45 teenagers, and 36 children.
What is the probability that a person chosen at random from the audience is not a teenager?
Answer:
55% or 0.55 or 11/20
Step-by-step explanation:
probability the person chosen is an adult or child out of all
so 19+36/19+36+45
55/100
The probability that the selected person is not a teenager is [tex]\frac{11}{20}[/tex].
What is probability?
Probability is a measure of happening or non happening of the outcomes of the random experiment.
Probability formulaP(E) = Total number favorable of outcomes/ Total number of outcomes
Where,
P(E) is the probability of an event.
According to the given question.
Total number of adults in the audience = 19
Total number of teenagers in the audience = 45
Total number of children in the audience = 36
Total audience = 19 + 45 + 36 = 100
Now, the probability that the selected person is teenager = [tex]\frac{45}{100} = \frac{9}{20}[/tex]
Therefore,
The probability that a selected person is not a teenager
= [tex]1 -\frac{9}{20}[/tex]
= [tex]\frac{11}{20}[/tex]
Hence, the probability that the selected person is not a teenager is [tex]\frac{11}{20}[/tex].

Answer:
m∠W = 134
Step-by-step explanation:
JGN is congruent to AIW and the names of the triangles are both in the same order. That may sound confusing but this means that:
J = A
G = I
N = W
So, if angle N is 134 then angle W is the same.

Michals basketball team practiced for 2hours 40 minutes yesterday and 3 hours 15 minutes today how much longer did the team practice today than yesterday
Answer:
35 minutes
Step-by-step explanation:
The is calculated using the Subtraction operation
The number of minutes longer the team practiced today than yesterday =
Number of minutes they practiced today - Number of minutes they practiced yesterday
Number of minutes they practiced today = 3 hours 15 minutes
Number of minutes they practiced yesterday = 2hours 40 minutes
The number of minutes longer the team practiced today than yesterday =
3 hours 15 minutes - 2hours 40 minutes
= 35 minutes
Therefore, the team practiced 35 minutes longer today than yesterday

if each square on the grid represents 400mi square how many miles will jacob's family travel?
Answer:
80miles
Step-by-step explanation:
Area of a square grid = L²
L is the side length of the grid
Given that Area of the square = 400mi square
400 = L²
L =√400
L = 20miles
To get the number of miles travelled, we will find its perimeter
P = 4L
P = 4(20)
P = 80miles
Hence Jacob's family travels 80miles
Select elther relation (If the set is a relation but not a function), function (If the set is both a relation and a function), or
neither (If the set is not a relation).
F=[(x, y) |x+y=10)
A. neither
B. Function
C. Relation
Answer:
B
Step-by-step explanation:
The given set F=[(x, y) |x+y=10) is a function.
What is a function?A relation is a function if it has only One y-value for each x-value.
The set F represents a relation since it contains ordered pairs of elements. Specifically, it contains all pairs (x, y) such that x+y=10.
For example, (2, 8) and (5, 5) are elements of F since 2+8=10 and 5+5=10.
However, it is not necessarily a function since it is possible for two different x values to have the same y value, which would violate the vertical line test for functions.
For example, both (2, 8) and (8, 2) are in F since 2+8=10 and 8+2=10.
Hence, the given set F=[(x, y) |x+y=10) is a function.
