Given A(4, 2) and B(-1, y) and the graph
of line t below, find the value of y so that
AB It.
Answer:
y = 9
Step-by-step explanation:
To solve this question we will use the property of perpendicular lines,
[tex]m_1\times m_2=-1[/tex]
Where [tex]m_1[/tex] and [tex]m_2[/tex] are the slopes of two lines perpendicular to each other.
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of a line which passes through the points A(4, 2) and B(-1, y) will be
[tex]m_1=\frac{y-2}{-1-4}[/tex]
[tex]=-\frac{y-2}{5}[/tex]
Slope of the line given in the graph [passing through (2, 4) and (-5, -1)]
[tex]m_2=\frac{4+1}{2+5}[/tex]
[tex]m_2=\frac{5}{7}[/tex]
From the property of perpendicular lines,
[tex]\frac{-(y-2)}{5}\times \frac{5}{7}=-1[/tex]
[tex]\frac{5(y-2)}{35}=1[/tex]
5y - 10 = 35
5y = 45
y = 9

Weighing the alternatives [Marks 2]
When weighing the various alternatives, how well each alternative fulfills the variables to consider can be expressed as scores. A different rating scale will be used to assess each alternative:
+2 very suitable
+1 quite suitable
0 neither suitable nor unsuitable
-1 not quite suitable
-2 not suitable at all
Note: Positive numbers (+2 or +1) indicate that the alternative is able to fulfill the variables, whereas negative numbers (-2 or -1) denote the opposite.
When weighing the alternatives, the suitability of each alternative can be expressed using a scoring system. The scoring system assigns scores to each alternative based on how well they fulfill the variables to consider.
The following rating scale is used:
+2: Very suitable
+1: Quite suitable
0: Neither suitable nor unsuitable
-1: Not quite suitable
-2: Not suitable at all
These scores reflect the extent to which each alternative meets the criteria or variables being evaluated. A higher positive score (+2 or +1) indicates that the alternative is highly suitable and fulfills the variables well. A score of 0 suggests that the alternative does not strongly align with the variables, neither positively nor negatively. Negative scores (-1 or -2) indicate that the alternative is not suitable and fails to fulfill the variables effectively.
By assigning scores to each alternative, decision-makers can compare and evaluate the different options based on their suitability and alignment with the desired criteria. This helps in making informed decisions and selecting the most appropriate alternative that best meets the desired objectives or requirements.

There is a 30% chance that you will be elected president of the history club. There is a 20% chance that your friend will be elected treasurer of the history club. You use a random number generator to randomly generate 50 numbers from 0 to 99. The results are shown in the table below. The digits 1, 2, and 3 in the tens place represent you being elected president. The digits 1 and 2 in the ones place represent your friend being elected treasurer. What is the experimental probability that you are elected president and your friend is elected treasurer? Write your answer as a fraction in simplest form.
Answer:
fraction form is 7/50
Step-by-step explanation:
The experimental probability is 2/25, written as a fraction in simplest form.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required event / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To find the experimental probability that you are elected president and your friend is elected treasurer,
We need to count the number of times the digits 1, 2, or 3 appear in the tens place and the digits 1 or 2 appear in the ones place.
We can then divide this count by the total number of digits (50) to get the experimental probability.
From the table,
We see that the digits 1, 2, or 3 appear in the tens place 12 times, and the digits 1 or 2 appear in the ones place 19 times.
However, we are interested in the number of times both events occur together, so we need to count the number of times that the digit 1, 2, or 3 appears in the tens place and the digit 1 or 2 appears in the ones place.
We can see that this occurs 4 times (tens place: 1, ones place: 1, 2, 1, 2).
The experimental probability that you are elected president and your friend is elected treasurer is:
4/50 = 2/25
Thus,
The experimental probability is 2/25, written as a fraction in simplest form.

the weights of a group of patients in a weight loss program range from 185 to 312. a doctor constructs a frequency distribution graph showing the number of children for each of the six age groups. what kind of graph would be appropriate for this distribution?
A bar graph is used to represent categorical data, while a histogram is used to represent continuous data.
The appropriate graph for the frequency distribution of a group of patients in a weight loss program that ranges from 185 to 312 pounds would be a histogram. This is because a histogram is a graphical representation of a frequency distribution. It is used to represent the distribution of a set of continuous data. A histogram is a graph that shows the number of times that each value appears in a set of data by grouping the data into classes of equal size. The number of values that fall within each class is represented by the height of a bar on the graph. The area of each bar is proportional to the frequency of the class.The six age groups will be grouped into classes that have the same size interval. The number of patients that fall within each class interval will be represented on the vertical axis, while the class intervals will be represented on the horizontal axis. The bars of the histogram will be plotted at the midpoints of each class interval. The height of each bar will represent the frequency of the class interval. It is important to note that a histogram is not the same as a bar graph.

find the volume of the ellipsoid x2 y2 5z2=100x2 y2 5z2=100.
The ellipsoid is defined by the equation x2 + y2 + 5z2 = 100. This equation can be rewritten as (x/10)^2 + (y/10)^2 + (z/2)^2 = 1. This is the equation of an ellipsoid with semi-axes of length 10, 10, and 2.
The volume of an ellipsoid is given by the triple integral of 1 over the ellipsoid. The bounds for the integral are determined by the semi-axes of the ellipsoid. In this case, the bounds are 0 <= x <= 10, 0 <= y <= 10, and 0 <= z <= 2.
The integral simply gives the volume of the ellipsoid. In this case, the integral is equal to 10000.

Step-by-step explanation:
a radio commercial for a loan company states "you pay 25 © a day for each $500 borrowed"if you borrow $1,693 for 120 days, what amount will you repay and what annual interest rate is the company actually charging (assume a 360 day year)
a) amount you repay= (round to two decimal places)
b) annual interest rate= (round to four decimal places)
a) The amount you will repay is approximately $12,000.
b) The annual interest rate charged by the loan company is approximately 18.2715%.
To calculate the amount you will repay and the annual interest rate charged by the loan company, we can follow these steps:
Step 1: Calculate the number of $500 increments for the loan amount:
Number of $500 increments = loan amount / $500
= $1,693 / $500
≈ 3.386
Since we can't have a fraction of an increment, we round up to 4.
Step 2: Calculate the daily payment:
Daily payment = 25 © * Number of $500 increments
= 25 © * 4
= $100
Step 3: Calculate the total repayment amount:
Total repayment amount = Daily payment * number of days
= $100 * 120
= $12,000
Step 4: Calculate the annual interest rate:
Annual interest rate = (Total repayment amount - Loan amount) / Loan amount * (360 / Number of days)
= ($12,000 - $1,693) / $1,693 * (360 / 120)
Now, let's perform the calculations:
Amount you repay ≈ $12,000
Annual interest rate ≈ (($12,000 - $1,693) / $1,693) * (360 / 120)
Calculating the annual interest rate:
Annual interest rate ≈ (($10,307) / $1,693) * 3
Rounding to four decimal places:
Annual interest rate ≈ (6.0905) * 3
≈ 18.2715
Therefore,
a) The amount you will repay is approximately $12,000.
b) The annual interest rate charged by the loan company is approximately 18.2715%.

Answer:
(x, y) = (6 8/11, -2 1/11)
Step-by-step explanation:
Add twice the second equation to the first:
(3x +2y) +2(4x -y) = (16) +2(29)
11x = 74 . . . . simplify
x = 74/11 = 6 8/11
Substitute this into the second equation to find y.
4(74/11) -y = 29
(26 10/11) - 29 = y = -2 1/11
The solution is (x, y) = (6 8/11, -2 1/11).

2.50x + 15.00 = 1.00x
what is x?
Answer:
x = -10
Step-by-step explanation:
Step 1: Write equation
2.50x + 15.00 = 1.00x
Step 2: Solve for x
Subtract 1.00x on both sides: 1.50x + 15.00 = 0Subtract 15.00 on both sides: 1.50x = -15.00Divide both sides by 1.50: x = -10Step 3: Check
Plug in x to verify it's a solution.
2.50(-10) + 15.00 = 1.00(-10)
-25 + 15.00 = -10
-10 = -10
Answer:
x = -10
Step-by-step explanation:
multiply both sides by 10:
2.50x*10+15*10=1.00x*10
Refine:
25x + 150 = 10x
Subtract 150 from both sides:
25x + 150 - 150 = 10x - 150
Simplify:
25x = 10x - 150
Subtract 10x from both sides:
25x - 10x = 10x - 150 - 10x
Simplify:
15x = -150
Divide both sides by 15:
15x/15 = -150/15
Simplify:
x = -10

Manny and Ada pool their money from a fundraiser Manny raised $7 less than twice what Ada raised. Manny made $45 more than Ada. How much money did Ada raise
Given parameters:
To solve this problem, we need follow it stepwisely.
Let the amount raised by Manny = M
amount raised by Ada = A
Now, let us go through the problem sentence by sentence and interpret it algebraically;
Manny raised $7 less than twice what Ada raised.Algebraically;
M = 2A - 7 ----- (I)
Manny made $45 more than Ada.M = A + 45 ----- (II)
Now that we have established two equations we can equate them and solve for A;
2A - 7 = A + 45
2A - A = 45 + 7
A = 52
Ada raised $52 during the fundraiser event.
If a = 1 and b = 2, how many times can bisection occur before there are no floating-point numbers in the interval (a, b) (in other words, a and b are adjacent floating-point numbers)
Bisection can occur an infinite number of times before there are no floating-point numbers in the interval (a,b).
Bisection refers to dividing an interval into two equal subintervals, as shown below:
First, divide the interval in half, and if the function changes sign over the interval, repeat the process with the subinterval that has the sign change until the endpoints are adjacent floating-point numbers.Thus, the interval [1,2] can be divided into two subintervals: [1,1.5] and [1.5,2]. Since both subintervals include floating-point numbers, we can bisect them again.
We now have four subintervals: [1,1.25], [1.25,1.5], [1.5,1.75], and [1.75,2]. All four subintervals include floating-point numbers, so we can bisect each of them. We now have eight subintervals, and all of them include floating-point numbers. We can continue this process indefinitely because there are an infinite number of floating-point numbers in the interval (1,2).
