The probability that Babby gets the same number of heads that Abby gets is 1/8 + 1/8 = 1/4. To solve this problem, we need to consider all the possible outcomes of Abby and Babby's coin tosses.
There are four possible outcomes for Abby's toss: heads or tails, and two outcomes for Babby's toss: heads or tails. Therefore, there are a total of 4 x 4 = 16 possible outcomes for the two coin tosses.
To determine the probability that Babby gets the same number of heads as Abby, we need to identify the outcomes where this happens. Abby can get either 0 or 1 heads, so we need to consider the outcomes where Babby gets 0 or 1 heads as well.
The possible outcomes where Abby gets 0 heads are:
Abby: tails, Babby: tails tails
Abby: tails, Babby: heads tails
In both of these outcomes, Babby also gets 0 heads, so the probability of this happening is 2/16 = 1/8.
The possible outcomes where Abby gets 1 head are:
Abby: heads, Babby: tails heads or heads tails
Abby: tails, Babby: heads heads
In two of these outcomes, Babby also gets 1 head, so the probability of this happening is 2/16 = 1/8. Therefore, the probability that Babby gets the same number of heads that Abby gets is 1/8 + 1/8 = 1/4.

99 cookies were diveded into three piles in the ratios of 1:1/2:1/3. how many cookies were in the middle pile
To the total of 99 cookies, there are 27 cookies in middle pile.
Let's call the number of cookies in the first pile "x". Then, the number of cookies in the second pile is 1/2 of x, or (1/2)x, and the number of cookies in the third pile is 1/3 of x, or (1/3)x.
We know that the total number of cookies is 99, so we can write an equation:
x + (1/2)x + (1/3)x = 99
To solve for x, we can first find a common denominator:
(6/6)x + (3/6)x + (2/6)x = 99
(11/6)x = 99
x = (6/11) * 99
x = 54
So, there are 54 cookies in the first pile, (1/2)x = (1/2)*54 = 27 cookies in the second pile, and (1/3)x = (1/3)*54 = 18 cookies in the third pile. In the middle pile there are 27 cookies.

consider a deck of 52 cards. one deals 4 cards in a row with no replacement. what is the probability that the first three cards are 3 aces and the last one is a king ?
The probability of the first three cards being 3 aces and the last one being a king is 1/66,300.
The probability of drawing an ace from a deck of 52 cards is 4/52 (since there are 4 aces in the deck), and the probability of drawing a king is 4/52 as well.
Since the cards are dealt with no replacement, the probability of drawing three aces in a row is
(4/52) × (3/51) × (2/50) = 1/5525
This is because after each card is drawn, there is one less ace in the deck, and one less card overall.
Now, we need to multiply this probability by the probability of drawing a king as the fourth card. Since there are only 48 cards left in the deck at this point (since three cards have already been drawn), the probability of drawing a king is
4/48 = 1/12
Therefore, the probability of drawing 3 aces and 1 king in a row is
(1/5525) × (1/12) = 1/66300

Based on your knowledge of the two data sets described below, would you expect a scatter plot describing the
two data sets to have a positive, a negative, or no correlation?
amount of gas in a car's gas tank and the total distance the car has traveled since last being filled with gas
Based on my knowledge, I would expect a negative correlation between the amount of gas in a car's gas tank and the total distance the car has traveled since last being filled with gas.
As the car travels, the amount of gas in the tank decreases. Thus, if the car has traveled a long distance since being filled up, it is likely that there is less gas in the tank. Therefore, there should be a negative correlation between the amount of gas in the tank and the distance traveled, meaning that as the distance traveled increases, the amount of gas in the tank decreases.
A scatter plot of these two variables should show a downward-sloping trend, indicating the negative correlation.
Therefore the correct answer is negative correlation.

Explain how to determine whether two ratios are equivalent
Answer:
Ratios are fractions, right? Set the two fractions equal to each other and then cross-multiply them. If each side of the equation is equal, then the ratios are equal; if not, then the ratios are not equivalent.
Ex. 1
Comparing ratios 4:2 and 2:1
[tex]\frac{4}{2} = \frac{2}{1}[/tex]
Cross-multiplying, we get 4 = 4, but we can also simplify each side of the equation to get 2 = 2.
Ex. 2
Comparing ratios 3:5 and 6:7
[tex]\frac{3}{5} =? \frac{6}{7}[/tex]
Cross-multiply, we get 21 = 30, so the ratios are not equal. This is an example of a case where you can't simplify the ratios.
Ex. 3
Comparing rations 5:12 and 10:24
[tex]\frac{5}{12} = \frac{10}{24}[/tex]

Find the surface area of the triangular prism shown below. units^2 2 5, 5, 7, 4, 6
Therefore, the surface area of the given triangular prism is approximately 126.56 square units.
What is surface area?Surface area is a measure of the total area that the surface of a three-dimensional object occupies. It is the sum of the areas of all the faces or surfaces of an object. Surface area is usually expressed in square units, such as square inches, square centimeters, or square meters, depending on the unit system being used.
For example, if you have a cube with side length "s", its surface area can be calculated by finding the area of each face and adding them together. Since a cube has six square faces of equal size, the formula for its surface area would be:
Surface Area of Cube = 6s²
by the question.
To find the surface area of a triangular prism, we need to calculate the area of all its faces and then add them together.
First, let's find the area of the two triangular bases. Each base is a right triangle with base 5, height 4, and hypotenuse 7. We can use the Pythagorean theorem to calculate the height of the triangle:
[tex]4^2 + (5/2)^2 = h^2[/tex]
[tex]16 + 6.25 = h^2[/tex]
[tex]22.25 = h^2[/tex]
[tex]h = \sqrt(22.25)[/tex]= 4.71
So, the area of each base is:
[tex]A = 1/2 * base * height = 1/2 * 5 * 4.71 = 11.78[/tex]
Next, we need to find the area of the three rectangular faces. The two congruent rectangular faces have dimensions of 5 by 6, and the remaining rectangular face has dimensions of 7 by 6. The area of each rectangular face is simply the product of its dimensions:
[tex]A1 = 5 * 6 = 30[/tex]
[tex]A2 = 5 * 6 = 30[/tex]
[tex]A3 = 7 * 6 = 42[/tex]
Finally, we can calculate the total surface area of the prism by adding up the areas of all five faces:
[tex]Total surface area = 2A(base) + A1 + A2 + A3[/tex]
[tex]Total surface area = 2(11.78) + 30 + 30 + 42[/tex]

La suma de las edades de Andrés, Carlos y Rodolfo es de 90 años. La edad de Andrés excede en 4 años a la edad de Carlos y en 11 a la de Rodolfo. Determina las edades de los tres
Andrés is 35 years old, Carlos is 31 years old, and Rodolfo is 24 years old based on the sum is given.
Let's assume the age of Andrés is x years.
According to the problem, Carlos' age is (x - 4) years and Rodolfo's age is (x - 11) years.
Now, we know that the sum of their ages is 90, so we write an equation:
x + (x - 4) + (x - 11) = 90
Simplify following equation:
3x - 15 = 90
Adding 15 to both sides, we get:
3x = 105
Dividing by 3, we get:
x = 35
So Andrés' age is 35 years.

what is equation ?
An equation is a mathematical statement that asserts that two expressions are equal. In other words, an equation says that one expression on the left side of the equals sign is the same as the expression on the right side of the equals sign. An equation typically includes variables
In the given question,
To determine the equation of the line passing through the points (0,-3) and (2,0), we can use the slope-intercept form of a linear equation:
y = mx + b
where m is the slope and b is the y-intercept.
The slope of the line can be found using the formula:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (0,-3) and (x₂, y₂) = (2,0)
m = (0 - (-3)) / (2 - 0) = 3/2
So the equation of the line is:
y = (3/2)x - 3
Now we can check which ordered pair is a solution to this equation by plugging in the x and y values into the equation and seeing if it holds true.
A. (0,-3)
y = (3/2)x - 3
-3 = (3/2)(0) - 3
-3 = -3
This is true, so (0,-3) is a solution.
B. (2,0)
y = (3/2)x - 3
0 = (3/2)(2) - 3
0 = 0
This is true, so (2,0) is a solution.
C. (2,2)
y = (3/2)x - 3
2 = (3/2)(2) - 3
2 = 0
This is false, so (2,2) is not a solution.
D. (-3,0)
y = (3/2)x - 3
0 = (3/2)(-3) - 3
0 = -9/2
This is false, so (-3,0) is not a solution.
Therefore, the solutions to the equation represented by the graph are A. (0,-3) and B. (2,0).

Find the Length of the mi dsegment of the trapezoid. A. 42
b. 12. 5
c. 38. 5
d. 51. 5
The length of the midsegment of the trapezoid is 38.5. The midsegment is the line segment that connects the midpoints of the two parallel sides of the trapezoid. It divides the trapezoid into two congruent triangles.
To find the length of the midsegment of the trapezoid, we need to first find the midpoint of the two parallel sides of the trapezoid. To do so, we need to use the midpoint formula, which is (x1 + x2) ÷ 2, (y1 + y2) ÷ 2, where (x1, y1) and (x2, y2) are the coordinates of the two points.
For example, if the coordinates of the two points are (1,2) and (5,7), then the midpoint of the two points will be (1+5) ÷ 2, (2+7) ÷ 2 = (6, 4.5).
Once we have the coordinates of the two midpoints, we can use the distance formula to find the length of the midsegment. The distance formula is √((x2-x1)² + (y2-y1)²).
So if the coordinates of the two midpoints are (3,6) and (9,2), then the length of the midsegment will be √((9-3)² +(2-6)²) = √(36+16) = √52 = 38.5.

In the third week,130 more people went to the pool than in the second week. In the fourth week, 232 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
The percent decrease in the number of people who went to the local swimming pool over four weeks, starting with a record high of 1,060 people in the first week, was 20%.
To find the percent decrease in the number of people who went to the pool over the four weeks, we need to first find the total number of people who went to the pool over the four weeks and then calculate the percentage decrease from the first week to the fourth week.
Number of people in the first week = 1,060
Number of people in the second week = 1,060 - 110 = 950
Number of people in the third week = 950 + 130 = 1,080
Number of people in the fourth week = 1,080 - 232 = 848
Total number of people over the four weeks = 1,060 + 950 + 1,080 + 848 = 3,938
Percentage decrease in the number of people who went to the pool over the four weeks = ((1,060 - 848)/1,060) * 100% = 20%
Therefore, the percent decrease in the number of people who went to the pool over the four weeks is 20%.

he transfers the total amount to another bank offering 12% per annum
a. How much interest did he get at the end of 7 years
b. Calculate the total amount he received at the end of 7 years
At the end of 7 years:
a. The man received approximately GHZ 6425.13 as interest.
b. The total amount received by the man is approximately GHZ 22,294.80.
The interest for the first 4 years at 3% compound interest:
Principal amount (P) = GHZ 14,100.00
Rate of interest (R) = 3% = 0.03
Time period (T) = 4 years
The formula for compound interest:
[tex]A = P (1 + R)^T[/tex]
A = 14,100 x (1 + 0.03)⁴
A = 14,100 x (1.03)⁴
A ≈ GHZ 15,869.67
Interest for the first 4 years = A - P
Interest = 15,869.67 - 14,100
Interest ≈ GHZ 1769.67
The total amount at the end of 7 years at 12% per annum:
(P) = GHZ 15,924.57
(R) = 12% = 0.12
(T) = 3 years (remaining 7 years - initial 4 years)
A = 15,869.67(1 + 0.12)³
A = 15,869.67(1.12)³
A ≈ GHZ 22,294.80
a. Interest for the remaining 3 years = A - P
Interest = 22,294.80 - 15,924.57
Interest ≈ GHZ 6425.13
b. Total amount received at the end of 7 years = Principal amount + Interest for 4 years + Interest for 3 years
Total amount = 14,100 + 1769.67 + 6425.13
Total amount ≈ GHZ 22,294.80

The resultant substraction value of the sum of three hundredths and 256 tenths from 41435 hundredths is equals to the 388.72.
Subtraction is one of the four arithmetic operations along with addition, multiplication and division. Subtraction is an operation representing the removal of an object from a collection. This is indicated by the symbol '-'. For example, there are 5 − 2 books meaning 5 books with 2 taken away, resulting in a total of 3 books. We have sum of three hundredths and 256 tenths. First, 3 hundredths means 3 out of 100, which can be denoted as = 3/100 = 0.03. Similarly, 256 tenth means 256/10 = 25.6. So, the sum of three hundredths and 256 tenths = 25.60 + 0.03 = 25.63 and 41435 hundredths = 414.35. Now, substract 25.63 from 414.35

AO is base {of both traingle's}
Now, ∆AOC= 1/2*CO*AO--1
and, ∆ COD = 1/2 *CO*AO--2
∆AOC= ∆COD {from above 1 and 2}

The table of values is completed below and the function of the sequence is T(n) = n(n + 2)
Completing the table of valuesFrom the question, we have the following parameters that can be used in our computation:
Pattern Counters
1 3
2 8
3 15
4 24
When the pattern is 5, we have
Counters(5) = 5 * (6 + 1)
So, we have
Counters = 35
So, the table is
Pattern number 1 2 3 4 5
Number of counters 3 8 15 24 35
The expression for the n-th termIn (a), we have
Counters(5) = 5 * (6 + 1)
Express 6 as 5 + 1
So, we have
Counters(5) = 5 * (5 + 1 + 1)
So, we have
Counters(n) = n * (n + 1 + 1)
As an n-th term, we have
T(n) = n(n + 2)
Hence, the function is T(n) = n(n + 2)
