The relative frequencies for all pets are given-
The relative frequency for dog is 0.4.
The relative frequency for cat is 0.35.
The relative frequency for bird is 0.15.
The relative frequency for fish is 0.1
What is relative frequency?The ratio of the total number of events occurring in a scenario to the number of times an event occurs is known as relative frequency.
Relative Frequency = Subgroup frequency/ Total frequency.
Relative Frequency = f/ n.
where, f = total frequency
n = subgroup frequency
Calculation for the relative frequencies of the pet types:
(1) Relative frequency for dog:
Total frequency is 20.
The frequency for dog is 8.
Relative frequency for dog = frequency for dog/total frequency
= 8/20
= 0.4
Relative frequency for dog = 0.4.
(2) Relative frequency for cat:
Total frequency is 20.
The frequency for cat is 7.
Relative frequency for cat = frequency for cat/total frequency
= 7/20
= 0.35
Relative frequency for cat = 0.35.
(3) Relative frequency for bird:
Total frequency is 20.
The frequency for bird is 3.
Relative frequency for bird = frequency for bird/total frequency
= 3/20
Relative frequency for bird = 0.15.
(4) Relative frequency for fish:
Total frequency is 20.
The frequency for fish is 2.
Relative frequency for fish = frequency for fish/total frequency

1. How many tolls will Stephanie pay?
2. What is the total cost of a one-way trip?
There are 3 tolls where Stephanie pays $ 4.05.
What is Distance?The distance between two points is the length of the path connecting them.
Here,
Distance covered by Stephanie = 12 1/4 miles

Distance between two toll tax = 3 1/2 miles
= 3.5 miles
Number of Tolls = Total distance covered / Distance between two tolls
= 12.25 / 3.5
= 3.5
≈ 3 tolls.
Cost of 1 toll = $ 1.35
Total amount paid on toll = 3 X 1.35

Find the principal which amounts to $918 in 1 year at a simple interest
of 2% per annum
Answer:
P = $900
Step-by-step explanation:
Simple Interest Formula: [tex]A = P(1+rt)[/tex]
Where A is the final amount,
P = Principal
r = Interest Rate in Percent or [tex]\frac{r}{100}[/tex] per annum
t = time in years
From the information given in the question,
A = $918
r = 2% per annum or [tex]\frac{2}{100}[/tex]
t = 1 year
Lets substitute these values to find P, the principal.
[tex]P(1+(\frac{2}{100} )(1))=918\\P(1+0.02)=918\\1.02P=918\\P = \frac{918}{1.02} \\=$900[/tex]
Therefore, P = $900

Part A Determine whether side-side-angle (SSA) is a valid means for establishing triangle congruence. In this case, you know the measure of two adjacent sides and the angle opposite to one of them. If it is a valid criterion, explain why. If it is not valid, use GeoGebra to create a counterexample demonstrating that it doesn’t work and give an explanation. (Hint: Try constructing a triangle where the known angle is opposite to the shortest known side.) If you construct a counterexample, take a screenshot of your work, save it, and insert the image in the space below.
In the case above, the side-side-angle (SSA) is no valid means for establishing triangle congruence.
What is the triangle congruence about?Using the image attached:
m angle A = M angle A

The algebraic expression for "m decreased by 47%" is m - 0.47m.
To translate "m decreased by 47%" into an algebraic expression, we first need to understand the meaning of the phrase. "Decreased by" indicates a subtraction operation, and "47%" represents 47 percent, which is equal to 0.47 in decimal form.
Let's break down the expression step by step:
"m" represents the original quantity we want to find.
"Decreased by" indicates subtraction.
"47%" is equivalent to multiplying the original value "m" by 0.47.
Combining all these elements, the algebraic expression for "m decreased by 47%" is:

For the following exercises, find (f ∘ g)(x) and (g ∘ f)(x) for each pair of functions

Answer:
The value of [tex]$(f \circ g)(x)$[/tex] is [tex]$4+4 x$[/tex] and [tex]$(g \circ f)(x)$[/tex] is [tex]$4 x-16$[/tex].
Step-by-step explanation:
It is given in the question functions f(x) as 4-x and g(x)=-4x.
It is required to find [tex]$(f \circ g)(x)$[/tex] and [tex]$(g \circ f)(x)$[/tex].
To find [tex]$(f \circ g)(x)$[/tex], substitute g(x)=-4x for x in f(x) and simplify the expression.
To find [tex]$(g \circ f)(x)$[/tex], substitute f(x)=4-x for x in g(x) and simplify the expression.

A spiral staircase turns $270^\circ$ as it rises 10 feet. The radius of the staircase is 3 feet. What is the number of feet in the length of the handrail
The number of feet in the length of the handrail is 17.3 ft.
The easiest way to see this is to imagine that we can "unfold" the spiral to create a rectangle
The bottom side of the rectangle is just the arc length of a circle with a radius of 3 ft turned through 270°= (3/4) of a whole revolution
(3/4) (2pi) (3) = (9/2)pi ft = 4.5 pi ft
The side of the rectangle will be the rise of the staircase = 10ft
And the diagonal of the rectangle will be the length of the handrail
We can use the Pythagorean Theorem to solve this
Handrail length = √ [ (4.5 pi)^2 + 10^2 ] ≈ 17.3 ft

What is the measure of arc ef
Answer: [tex]128^{\circ}[/tex]
Step-by-step explanation:
By the inscribed angle theorem, minor arc EG measures 92 degrees.
Since the circumference of a circle measures 360 degrees, arc EF measures [tex]360-140-92=128^{\circ}[/tex]
The measure of the arc EF = 128°.
What is an Arc?Arc is that part of the circumference of the circle which is formed by two points on the circle.
The angle subtended by an arc on the center of the circle is twice that it subtends on the circumference of the circle.
So,
The measure of arc EG = 2 * 46 = 92
The measure of arc GF = 140°
The complete circle has an angle of 360° at the center
The measure of the arc EF = 360 -mEG - mGF
The measure of the arc EF = 360 - 92 -140
The measure of the arc EF = 128°.
Therefore, The measure of the arc EF = 128°.

Answer:
(a) The number of positive zeros is either 2 or 0. The number of negative zeros is either 2 or 0.
Step-by-step explanation:
The possible numbers of real zeros can be found using Descarte's Rule of Signs.
RuleWhen signs of coefficients of terms of the polynomial are listed in order of decreasing degree, the number of sign changes can be counted. That number is the number of possible positive real zeros of the polynomial.
When the signs of odd-degree terms are changed, the number of sign changes becomes the possible number of negative real zeros.
The actual number of real zeros may be less by a multiple of 2. (The zeros may be complex, and complex zeros come in pairs.)
ApplicationThe signs of the terms in the given polynomial are ...
+ - + + + . . . . . 2 sign changes: 2 or 0 positive real zeros
When the signs of odd-degree terms are changed, they become ...
+ + + - + . . . . . 2 sign changes: 2 or 0 negative real zeros
Descarte's rule of signs lets us conclude ...
The number of positive zeros is either 2 or 0. The number of negative zeros is either 2 or 0.__
Additional comment
When we graph the function, we find there are no real zeros. All four of the zeros are complex.
