independent vs dependent equation5х – Зу = 10 бу = kx - 42
We will assume that we want to know if the system of equations is independent or dependent:
[tex]\begin{cases}5x-3y=10\text{ (1)} \\ 6y=kx-42\text{ (2)}\end{cases}[/tex]where k is a real number. We will try to find the solutions to the system, and we will try to give values to k for which the system becomes independent or dependent.
We will use substitution, we solve for the variable x on the first equation to obtain:
[tex]\begin{gathered} 5x-3y=10 \\ 5x=10+3y \\ x=\frac{10+3y}{5} \end{gathered}[/tex]And now we replace it onto the second equation:
[tex]\begin{gathered} 6y=k(\frac{10+3y}{5})-42 \\ 6y=\frac{10k+3ky}{5}-42 \\ 6y=\frac{10k+3ky-210}{5} \\ 30y=10k+3ky-210 \\ 30y-3ky=10k-210 \\ y(30-3k)=10k-210 \\ y=\frac{10k-210}{30-3k} \end{gathered}[/tex]And the value of x will be:
[tex]\begin{gathered} x=\frac{10+3(\frac{10k-210}{30-3k})}{5}=\frac{10+\frac{10k-210}{10-k}}{5} \\ =\frac{10(10-k)+10k-210}{5(10-k)} \\ =\frac{100-10k+10k-210}{50-5k} \\ =-\frac{110}{50-5k} \\ =-\frac{22}{10-k} \end{gathered}[/tex]This means that a solution of the system will be:
[tex]\begin{cases}x=-\frac{55}{10-k} \\ y=\frac{10k-210}{30-3k}\end{cases}[/tex]Now, for finding the values which make the system dependent. This happens when the lines have the same slope, this is, when:
[tex]\begin{gathered} \frac{-5}{-3}=\frac{k}{6} \\ \frac{5}{3}=\frac{k}{6} \\ 30=3k \\ 10=k \end{gathered}[/tex]We did the division of the opposite of the coefficient of x, over the coefficient of y. This means that the system will be independent for each value of k different than 10, and will be dependent for k=10.
There are 3 consecutive odd integers that sum to –9. What is the least of these integers?

The ratio of the number of oranges to the number of apples is 1 : 3.21 oranges were added and the ratio became 4 : 5. How many fruitswere there initially?
Answer
There were 15 oranges initially.
There were 45 apples initially.
Hence, there were (15 + 45) = 60 fruits there initially.
Explanation
Let the number of oranges be x
Let the number of apples be y
The ratio of the number of oranges to the number of apples is 1 : 3 implies:
[tex]\begin{gathered} x\colon y=1\colon3 \\ \frac{x}{y}=\frac{1}{3} \\ \text{Cross multiply} \\ y\times1=x\times3 \\ y=3x----i \end{gathered}[/tex]If 21 oranges were added and the ratio became 4 : 5, this implies:
[tex]\begin{gathered} (x+21)\colon y=4\colon5 \\ \frac{x+21}{y}=\frac{4}{5} \\ \text{Cross multiply} \\ 5(x+21)=4\times y \\ 5x+105=4y----ii \end{gathered}[/tex]To know how many fruits were there initially, solve the system of the equations:
[tex]\begin{gathered} \text{Substitute }y=3x\text{ into }ii \\ 5x+105=4(3x) \\ 5x+105=12x \\ \text{Combine the like terms} \\ 12x-5x=105 \\ 7x=105 \\ \text{Divide both sides by 7} \\ \frac{7x}{7}=\frac{105}{7} \\ x=15 \end{gathered}[/tex]x = 15 implies there were 15 oranges initially.
To get y, substitute x = 15 into equation (i):
[tex]\begin{gathered} y=3x----i \\ y=3\times15 \\ y=45 \end{gathered}[/tex]y = 45 implies there were 45 apples initially.
Hence, there were (15 + 45) = 60 fruits there initially.

Which normal distribution has a wider spread: distribution A with a mean of one and a standard deviation of two, or distribution B with a mean of two and a standard deviation of one?
The normal distribution with mean of one and standard deviation of two has the wider spread.
Normal distribution:
Normal distribution defines a symmetrical plot of data around its mean value, where the width of the curve is defined by the standard deviation.
Given,
Here we have the distributions,
Distribution A with a mean of one and a standard deviation of two, or Distribution B with a mean of two and a standard deviation of one
Now, we have to identify the normal distribution has a wider spread.
Here the normal distribution with a mean of 1 and standard deviation of 2 will be wider than a distribution with a mean of 2 and standard deviation of 2.
Because, the distributions with greater standard deviations indicate greater variability/spread of its variables around the mean.

Standard Position of Angles
An angle is in standard position if its vertex is located at the origin and one ray is on the positive x-axis.
The ray on the x-axis is called the initial side and the other ray is called the terminal side.
Positive angles are measured counterclockwise, negative angles are measured clockwise.
The angle of 110 degrees is positive so it must be measured counterclockwise. The angle -80 will be drawn clockwise.

yson does 75 sit-ups during his work out. He wants to increase his sit-ups by 15%. Which represents the new amount of sit-up
Answer:
he does 86 sit ups instead of 75 to increase by 15 percent
Step-by-step explanation:
Answer: The correct answer is 86.25 sit-ups (or round-up to 87 whole sit-ups).
Step-by-step explanation:
S = current amount of sit-ups (75)
S2 = Increased amount of sit-ups by 15%
The equation:
S2 = S + (S x .15)
S2 = 75 + (75 x .15)
S2 = 75 + 11.25
S2 = 86.25 sit-ups

The number of sick days an employee takes per year is believed to be about 12.
The mean purpose of null hypothesis is to verify or disprove the proposed statistical assumptions, also is usually associated with just ‘equals to’ sign as a null hypothesis can either be accepted or rejected.
If you wish to test the claim that mean number of sick days an employee takes per year is not equal to 12 days, then the null hypothesis is "the mean number of sick days an employee takes per year is equal to 12 days".
Then, the correct null hypothesis is:

Answer
The highest height attained by the rocket = 1194.4 feet
Explanation
The height of the rocket, y, in feet as a function of the time, x in seconds as
y = -16x² + 261x + 130
We are then asked to find the maximum height reached by the rocket
To do this, we would use the differentiation analysis to obtain the maximum of this function.
At maximum point for any function,
The first derivative = (dy/dx) = 0
The second derivative = (d²y/dx²) < 0
y = -16x² + 261x + 130
First derivative
(dy/dx) = -32x + 261 = 0
32x = 261
Divide both sides by 32
(32x/32) = (261/32)
x = 8.15625 s
We can then substitute this value of x (time) into the equation to get the maximum height (y)
y = -16x² + 261x + 130
At x = 8.15625 s,
y = -16 (8.15625)² + 261 (8.15625) + 130
= -1064.39 + 2128.78 + 130
= 1194.39
= 1194.4 feet to the nearest tenth.

20. Damilola wrote the equation h = 2d + 1 to represent the height of hisplant, h, after a certain number of days. In this relationship, he identified has the dependent variable, and d as the independent variable. Do youagree? Why or why not?*
As we can see we have the next equation
[tex]h=2d+1[/tex]where h is the dependent variable and d is the independent variable
So we agree, because d does not depend on the height, but the height depends on the days
In order words
An independent variable is a variable that represents a quantity that is modified in an experiment. In this case d
A dependent variable represents a quantity whose value depends on how the independent variable is modified. In this case h

Seniors at a high school are allowed to go off campus for lunch if they have a grade of A in all their classes or perfect attendance. An assistant principal in charge of academics knows that the probability of a randomly selected senior having A's in all their classes is 0.1. An assistant principal in charge of attendance knows that the probability of a randomly selected senior having perfect attendance is 0.16. The cafeteria staff know that the probability of a randomly selected senior being allowed to go off campus for lunch is 0.18. Use the addition rule of probability to find the probability that a randomly selected senior has all As and perfect attendance.
Given:
Probability a randomly selected senior has A = 0.1
Probability a randomly selected senior has a perfect attendance = 0.16
Probability a randomly selected senior is being allowed to go offf campus: P(A or B) = 0.18
Let's find the probability that a randomly selected senior has all As and a perfect attendance using addition rule for probability.
Apply the formula below:
P(A or B) = P(A) + P(B) - P(A and B)
Rewrite for P(A and B):
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = 0.1 + 0.16 - 0.18
Therefore, the probability that a randomly selected senior has all As and perfect attendance is
