Answer: 8 dogs
Step-by-step explanation:
There are 96 animals in the shelter.
1/3 are ferrets which means that the number of ferrets is:
= 1/3 * 96
= 32 ferrets
Remaining animals:
= 96 - 32
= 64 animals
7/8 of the remaining are rabbits:
= 7/8 * 64
= 56 rabbits
Number of dogs is what is left so:
= 64 - 56
= 8 dogs

The solution is Option B.
Number of seats for the students is given by the equation A = 231 seats
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of seats for the students be A
Now , the equation will be
The total number of buses = 3 buses
The total number of seats on each buses = 80 seats
So , the total number of seats = number of buses x number of seats on each buses
Substituting the values in the equation , we get
The total number of seats = 80 x 3
The total number of seats = 240 seats
Now , the teachers has 3 seats each on 3 buses
So , the number of seats for teachers = 3 x 3 = 9 seats
And , the remaining number of seats = total number of seats of students
The total number of seats for students A = total number of seats - number of seats for teachers
Substituting the values in the equation , we get
The total number of seats for students A = 240 - 9
The total number of seats for students A = 231 seats
Therefore , the value of A is 231 seats
Hence , the number of seats for students is 231 seats

TOLL ROAD Mr. Espinoza randomly chooses one of five toll booths when
entering a toll road when driving to work. What is the probability he will
select the middle toll booth on Monday and Tuesday?
Answer: Assuming that the selection of the toll booth is a random and independent event, the probability that Mr. Espinoza chooses the middle toll booth on Monday is 1/5 (or 20%), since there are five total toll booths and the middle booth is one of those options. Similarly, the probability that he chooses the middle booth on Tuesday is also 1/5 (or 20%).
To find the probability that he chooses the middle booth on Monday and Tuesday, we can multiply the probabilities of each event.
Probability of selecting middle booth on Monday AND selecting middle booth on Tuesday = (1/5) * (1/5) = 1/25 = 0.04 or 4%
So, Mr. Espinoza will select the middle toll booth on Monday and Tuesday with a probability of 4%. This means that the chance that both events will happen is low and quite rare, but not impossible.

Find the lengths of the diagonals of rectangle WXYZ.
WY = 14x + 10
XZ = 11x + 22
The length of each diagonal is
units.
The length of each diagonal is √(196x^2 + 816x + 324) units.
What is the formula for diagonal length?The diagonal of a rectangle can be estimated using the hypotenuse formula, such as using the Pythagorean theorem calculator.
WX^2 = WY^2 + XZ^2
Given that WY = 14x + 10 and XZ = 11x + 22, we can substitute those values in the equation:
WX^2 = (14x + 10)^2 + (11x + 22)^2
WX^2 = 196x^2 + 816x + 324
WX = √(196x^2 + 816x + 324)
The same goes for the other diagonal, WZ.
WZ = √(196x^2 + 816x + 324)
So, the length of each diagonal is √(196x^2 + 816x + 324) units.

Explain about the probability?Probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
By dividing the number of preferable possibilities by the total number of potential outcomes, probability, which measures the likelihood that an event will occur, is obtained. A coin flip is the most basic illustration. There are only two outcomes that can occur when you flip a coin: either heads or tails.
The basic probability formula is: Probability = Number of Favorable Outcomes / Total Number of Outcomes. or P(A) = f/N

One-fourth
One-half
StartFraction 1 Over 8 EndFraction
StartFraction 1 Over 16 EndFraction
answer is one fourth
What the height would need for this curve to be a density curve is; One-half
How to interpret Density Curves?The criteria for a curve to be a density curve is as follows;
1. The curve must always be non-negative. This tells us that the y-value of the curve must be greater than or equal to 0 at every given point.
2. The area under the curve must always be equal to 1.
Now, we are told that the curve starts at (-2, 0) and then goes to (5, question mark), and then goes down to (6, 0),.
This means that the area under the curve will be a trapezoid that has a height of question mark and then bases of length 3 (from -2 to 5) and length 1 (from 5 to 6).
The area of this trapezoid will be equal to the sum of the bases times the height divided by 2, or:
Area = ((3 + 1) × question mark)/2
Since the area under the curve must be equal to 1, we can set up the equation:
1 = ((3 + 1) × question mark) / 2
Solving for question mark, we will:
The question mark = 2/4
The question mark = 1/2
Therefore, we can conclude that the height of the curve is 1/2

Tierra is making steps for a doll house. She has cut a piece of wood that measures 1. 5 centimeters wide and 30 centimeters long. Each step will measure 15 millimeters by 4 millimeters. She will make 21 steps for her doll house. Which are the dimensions of the wood that remains after Tierra finishes making the 21 steps?
The dimensions of the wood that remains after Tierra finishes making the 21 steps is 1.185 cm by 21.6 cm
In Mathematics, dimensions are referred to as measures of size such as length, width, and height of an object or a shape.
A square has sides of equal dimensions.
A rectangle has length and width as its dimensions that define the area of a rectangle.
Also, dimension is used widely to term the figure as one-dimensional, two-dimensional or three-dimensional.
Wood = 1.5 cm by 30 cm
Each cut = .15 mm by 4 mm
Steps = 21
The remaining dimension is calculated as:
Remaining = 1.5 cm - 21 * .15 mm by 30 cm - 21 * 4 mm
Express mm as cm
Remaining = 1.5 cm - 21 * .015 cm by 30 cm - 21 * 0.4 cm
Evaluate the difference
Remaining = 1.185 cm by 21.6 cm
Hence, the dimensions of the wood that remains after Tierra finishes making the 21 steps is 1.185 cm by 21.6 cm

A standard deck of 52 cards contains four suits: clubs, spades, hearts, and diamonds. Each deck contains an equal number of cards in each suit. Rochelle chooses a card from the deck, records the suit, and replaces the card. Her results are shown in the table. Cards Suit Observed Frequency Clubs 29 Spades 13 Hearts 15 Diamonds 23 How does the experimental probability of choosing a heart compare with the theoretical probability of choosing a heart
The theoretical likelihood of selecting a heart is 1/16 times higher than the actual likelihood.
In the given question, we have to find the experimental probability of choosing a heart compare with the theoretical probability of choosing a heart.
We are aware that a deck's total number of cards= 52
Total number of hearts = 13
Then the theoretical probability of getting a heart = Number of cards have hearts/Total cards
Then the theoretical probability of getting a heart = 13/52
Then the theoretical probability of getting a heart = 1/4
Then the theoretical probability of getting a heart = 0.25
Cards chosen by Rochelle : Clubs 29, Spades 13, Hearts 15, Diamonds 23
Total cards = 80
The experimental likelihood of experiencing a heart attack = Number of cards have hearts/Total cards
The experimental likelihood of experiencing a heart attack = 15/80
The experimental likelihood of experiencing a heart attack = 3/16
The experimental likelihood of experiencing a heart attack = 0.185
Since, 0.25 > 0.1875 so, Theoretical probability > Experimental probability
and,
Theoretical probability = 0.25-0.1875
Theoretical probability = 0.0625
Theoretical probability = 625/10000
Theoretical probability = 1/16
Hence, the theoretical likelihood of selecting a heart is 1/16 times higher than the actual likelihood.
