Step-by-step explanation:
33) A student has a set of cards, Each cara nas a picture of one shape.
The table shows the number of cards that have a picture of each
shape. The student will randomly select one card from the set.
Shape Cards
Circle = 8
Pentagon = 12
Rectangle = 10
Square = 6
Triangle = 4
Which statement is true?
A) The probability of selecting a card with a picture of a circle is 5/8, and the probability of selecting a card that is not a picture of a circle is 3/8
B) The probability of selecting a card with a picture of a circle is 3/8, and the probability of selecting a card that is not a picture of a
circle is 5/8
C) The probability of selecting a card with a picture of a circle is 1/5, and the probability of selecting a card that is not a picture of a
circle is 4/5
D) The probability of selecting a card with a picture of a circle is 4/5, and the probability of selecting a card that is not a picture of a circle is 1/5
Answer: C The probability of selecting a card with a picture of a circle is 1/5, and the probability of selecting a card that is not a picture of a
circle is 4/5
Step-by-step explanation:
First you need to find the total amount of cards in the set by adding up all of the cards: 8 + 12 + 10 + 6 + 4 = 40
Then to find the probability of selecting a circle divide the number of cards that have a circle by the total number of cards: 8/40
You can simplify it to be 1/5 since 8/8 = 1 and 40/8 = 5
So the probability of a circle is 1/5
This means that the probability for all of the other shapes that are not a circle have to be 4/5-- but you can check by adding up the rest then dividing by 40:
12 + 10 + 6 + 4 = 32
32/40 --> 32/8 = 4 & 40/8 = 5

Bob's Bagels sells 10 bagels for $11.00, and Donny's Bagels sells 4 bagels for $3.00.
Which is the better deal? What fractions do you compare to find the better deal? Will the deal have a lower or higher ratio of dollars per bagel?
Answer:
The better deal is 4 bagels for $3.00.
The fractions you would compare would be:
11 / 10 = 1.10 and
3 / 4 = 0.75
A "deal" would refer to the better value. In this case the better deal has a lower ratio of dollars to bagels.
Step-by-step explanation:
Which is the better deal?
First, you have to get the 10 and 4 to the same number.
10 x 4 = 40
4 x 10 = 40
Then, you multiply $11 by the same number as the 10.
Now multiply $3 by the same number as the 4.
$11 x 4 = $44
$3 x 10 = $30
So, which one has the lowest prize?
Donny's Bagels
What fractions do you compare with the better deal?
Bob's Bagels: 44/40
Donny's Bagels: 30/40
Now, you'll have to make these fractions as low as possible.
Bob's Bagels:
44 divided by 4 = 11
40 divided by 4 = 10
Donny's Bagels:
30 divided by 5 = 6
40 divided by 5 = 8
The fractions are: 11/10 and 6/8. But, 11/10 is an improper fraction.
To make it a mixed number, you'll have to follow these steps:
Divide the numerator by the denominator: 11 divided by 10 = 1.1Write down the whole number answer: 1Then write down any remainder above the denominator: 1 1/10Bob's Bagels fraction: 1 1/10
Will the better deal have a lower or higher ratio of dollars per bagel?
The better deal will have a lower ratio of dollars per bagel.

The most appropriate choice for probability of an event will be given by-
Probability of getting a number greater than 2 on a 8 sided die is 0.75
What is probability of an event?
Probability of an event gives the information about how likely an event is going to happen.
Probability is calculated by number of favourable outcomes divided by total number of outcomes.
Probability is always greater than or equal to zero and less than or equal to 1
Probability of unsure event is 0 and probability of sure event is 1.
Calculation
Here,
Favorable outcomes (Numbers greater than 2 on a eight - sided die) = {3, 4, 5, 6, 7, 8}
Number of favourable outcomes in rolling a 8 sided die = 6

Youth soccer fields vary in size per the age of the players. The field for the 9 and 10 year-old players was 75 yards long by 45 yards wide. The field for the 11- 14 year old players was proportionally larger. If the length of the field for the 11-14 year old players was 100 yards, what was the width?
Answer:
60 yards.
Step-by-step explanation:
We can use the concept of proportional relationships to find the width of the field for 11-14 year-old players.
The ratio of length to width of the field for 9 and 10 year-old players is:
75 yards : 45 yards
We can simplify this ratio by dividing both sides by 15:
5 yards : 3 yards
This means that for every 5 yards in length, the field is 3 yards wide.
Now we can use this ratio to find the width of the field for 11-14 year-old players:
Ratio of length to width for 11-14 year-old players:
100 yards : w yards
where w is the unknown width.
We can set up a proportion using the ratio we found for the 9 and 10 year-old players:
5 yards : 3 yards = 100 yards : w yards
To solve for w, we can cross-multiply:
5 yards x w yards = 3 yards x 100 yards
5w = 300
w = 60
Therefore, the width of the field for 11-14 year-old players is 60 yards.

Step-by-step explanation:
The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Step-by-step explanation:
5x + 15y =20 multiply all by 3 to get 15x
15x +45y=60
- 3x +25y =75 multiply all by -5 to get 15x
15x -125y = -375
rewrite ans together
15x +45y=60
15x -125y = -375
-80y = -315
y = -315/ - 80
y = 3.9375 = y= 4 substitute to find x
5x + 15(4 )=20
5x +60 = 20
5x=-40
x= -40/5
x=-8

In two or more complete sentences, compare the number of x-intercepts in the graph of f(x) = x^2 to the number of x-intercepts in the graph of g(x) = -x^2 -5. Be sure to include the transformations that occurred between the parent function f(x) and its image g(x).
Answer:
f(x) = x^2 has one x-intercept and g(x) = x^2 -7 has two x-intercepts. For f(x) = x^2 to equal g(x) = x^2 -7 you must traslate f(x) = x^2 down seven units.

Brainlist for positive attitude and correct answer :D
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D
In 2020, Forest A had an area of about 4000 acres and Forest B had an area of about 3600 acres. Researchers expect deforestation to cause the area of Forest A to decrease at a rate of 105 acres per decade and the area of Forest B to decrease at a rate of 30 acres per decade. In what year do they expect the areas of the forests to be the same?
Answer:
In about 2073, 3440 acres
Step-by-step explanation:
Determine the equation for each forest. Forest A: y=-105x+4000 Forest B: y=-30x+3600There are a number of ways to solve a system of equations, but for this we are first going to solve for x when -105x+4000=-30x+3600. In this case, x=5 1/3.Then, we are going to plug 5 1/3 in as x into one of our equations. To double check you have this right, you may do both. If our equation is y=-30(5 1/3)+3600, then y=3440.Add 5 1/3 decades or about 53 years to 2020.Therefore, they expect the area of the forests to be the same in about 2073. At this time, both will have an area of about 3440 acres.
In 2073 the areas of the forests to be the same.
What is 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. LHS = RHS is a common mathematical formula.
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:
Forest A had an area of about 4000 acres and Forest B had an area of about 3600 acres.
If Forest A to decrease at a rate of 105 acres per decade and the area of Forest B to decrease at a rate of 30 acres per decade.
let the number of decades occur be x
So, the equation is
4000 - 105x= 3600 - 30x
400 = 75 x
x= 5.33
x= 53.3 years
Hence, In 2073 the areas of the forests to be the same.
