In the given equation we get the following values:
M = 2
C = 5
Given, we have the equation:
Y = 2x + 5
we are asked to determine the following values of m and c.
The given equation is in the form of slope intercept form.
slope intercept form is given as:
y = mx+c
hence :
M = 2 and
C = 5
One of the most popular ways to represent a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula can be used to determine the equation of a line ( the y-coordinate of the point where the line intersects the y-axis).
The slope intercept form is a technique for figuring out a straight line's equation in the coordinate plane. This relationship will be the equation of a straight line:
the line must satisfy the coordinates of every point along it.Any location that is not on the line will not satisfyhence we get the required values.

The student academic group on a college campus claims that freshman students study at least 2.5 hours per day, on average. One Introduction to Statistics class was skeptical. The class took a random sample of 30 freshman students and found a mean study time of 135 minutes with a standard deviation of 44 minutes. At
= 0.01 level, is the student academic group's claim correct?
1. What is the p-value
The p-value of this sample proportion is equal to 0.0360.
At the 0.01 (1%) significance level, there isn't enough evidence to conclude that freshmen students study less than 2.5 hours per day, on an average.
How to calculate value of the test statistic?For this statistical study, we would use a t-test statistic and the null and alternative hypotheses would be given by:
H₀: p ≥ 150 minutes
H₁: p < 150 minutes
Mathematically, the t-test statistic can be calculated by using this formula:
[tex]t=\frac{x\;-\;\mu}{\frac{\delta}{\sqrt{n} } }[/tex]
Where:
x represents the sample mean.μ represents the mean.σ represents the standard deviation.n represent the number of students.Substituting the given parameters into the formula, we have;
t-test, t = (135 - 150)/(44/√30)
t-test, t = (-15)/8.0333
t-test, t = -1.8672
From the t distribution table, the p-value is given by:
p-value = P(t < -1.8672)
p-value = 0.0360
Since the p-value (0.0360) is greater than the significance level (0.01), we fail to reject the null hypothesis because there is insufficient evidence to claim that the mean time of the freshman students is less than 2.5 hours per day.

The binomial distribution is a parametric probability distribution with two parameters, X and B. For a large number of trials, n, binomial probability tends to follow a continuous normal probability distribution.
What is meant by binomial distribution?The binomial distribution is a type of probability distribution that models the likelihood of one of two outcomes given a set of parameters. It sums up the number of trials when each trial has the same chance of achieving a single outcome.
Therefore,
The following is the definition of the Binomial distribution's probability mass function:
P (X = x) = (n x)p x(1p)n x, where x = 0, 1, 2, 3,..., n
Given,
Probability of defective, p = 0.03
Number of bulbs, n = 144
(i) The required probability is P(X = 5).
P(X = 5) = (1445) 0.035(1 − 0.03)144 − 5
= 144151 × (144 − 5) 1 × 0.035(1 − 0.03)144 − 5 ≈ 0.169
Within a carton of 144 bulbs, there is a 0.169 percent chance that 5 of them will be defective.
(ii) The required probability is P(X>2).
P(X>2) = 1 − P(X≤2)
= 1 − P(X = 0) − P(X = 1) − P(X = 2)
= 1 − 144101 × (144 − 0)10.030
Then simplifying,
(1 − 0.03)144 − 0 − 14411 × (144 − 1) 10.031 (1 − 0.03)144 − 1 − 14412 × (144 − 2)10.032 (1 − 0.03)144 − 2
= 1 − 0.01245 − 0.0554 − 0.1226
= 0.810
There is a 0.810 percent chance that there will be more than two faulty bulbs in a carton of 144 bulbs.

What is a correlation coefficient?A correlation coefficient measures the strength of the linear relationship between two variables.
Correlation coefficients usually range between -1 to 1, and they show how one variable moves in relation to another.
A positive correlation coefficient indicates that the two variables move uniformly in the same direction, while a negative correlation coefficient shows the opposite.
A zero correlation coefficient shows no linear relationship between the two variables.

Roberto is applying for a mortgage. He has a monthly gross income of $3,500. The home he would like to buy has monthly payments for the following: $1,000 mortgage, $150 property taxes, $75 homeowners insurance premium, and $75 mortgage insurance premium. Roberto also has other monthly debts totaling $500 per month. Based on the Federal Housing Administration (FHA) total fixed payments-to-income ratio, would he qualify for the mortgage loan?
Based on the Federal Housing Administration's (FHA) total fixed payments-to-income ratio, Roberto would not qualify for the mortgage loan.
What is the fixed payments-to-income ratio?The Federal Housing Administration (FHA) allows 31% of a person's income to settle housing costs (as the front-end ratio) and 43% (as the back-end ratio) towards housing expenses and other long-term debt.
Monthly gross income = $3,500
Monthly payments for Housing:
Monthly mortgage = $1,000
Property taxes = $150
Homeowners insurance premium = $75
Mortgage insurance premium = $75
Total monthly housing costs = $1,300
Other monthly debts per month = $500
Total monthly payments = $1,800
Minimum front-end ratio = 31% = $1,085 ($3,500 x 31%)
Maximum back-end ratio = 43% = $1,505 ($3,500 x 43%)
Thus, using the FHA fixed payments-to-income ratio, Roberto would not qualify.

period has a daily balance of $145. What is
the finance charge, on the average daily
balance, for this 1 month period?
28.5% = 0.285
Hint: Divide the decimal by 12 to get the monthly interest
rate. Do not round that answer. Take that answer and
multiply it to the average daily balance.
Finance charge = $[?]
Round to the nearest hundredth
The finance charge on the average daily balance for , this 1 month period is $3.45 .
In the question ,
it is given that ,
the daily balance over the period of 1 month = $145
The APR rate of interest = 28.5%
the monthly APR rate of interest = (28.5%)/12 = 2.375%
the finance charge for the 1 month period can be calculated using the formula .
finance charge = (daily average balance)×(monthly rate of interest)
Substituting the values , we get
finance charge = 145 × 2.375%
= 145 × 0.02375

Answer: (0,0) (12,0)
Step-by-step explanation:
y=4x³-96x²+576x
Let y=0
Hence,
4x³-96x²+576x=0
Divide both parts of the equation by 4:
x³-24x²+144x=0
x(x²-24x+144x)=0
x=0
Thus, (0,0)
x²-24x+144=0
x²-2(x)(12)+12(12)=0
x²-2(x)(12)+12²=0
(x-12)²=0

The value of the function when the value of x is 5 is 29.
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
[tex]f(x)= \left \{ {{x^3 \;\;\;\;\;\; x < -3} \atop {2x^2-9\;\;\;-3\leq x < 4}} \atop {5x+4\;\;\;x > 4}}\right.[/tex]
As the value of the function is to be found when the value of x is 5.
So, we can write the function as,
f(5) = 5x + 4

If a function is symmetrical about the origin, when y is replaced with (-y) and x is replaced with (-x), the resulting function will be equal to the original function.
Original function:
[tex]y=-\dfrac{1}{8}x^3[/tex]
Replace y with (-y) and x with (-x):
[tex]\implies -y=-\dfrac{1}{8}(-x)^3[/tex]
[tex]\implies -y=-\dfrac{1}{8}\cdot -x^3[/tex]
[tex]\implies -y=\dfrac{1}{8}x^3[/tex]
Multiply both sides by -1:

The given steps describe constructing a parallel line using a compass and straightedge given line and a point E that is not on line .
Step 1: Draw a line through point E that intersects line , and label the point of intersection, C.
Step 2: Place the point of the compass on C and draw an arc that crosses both lines.
Step 3: Without adjusting the compass width, move the compass to point E and draw an arc that has a similar orientation to the first arc drawn.
Step 4: Set the compass width to where the lower arc crosses the two lines.
Step 5: Move the compass point to the upper arc on the intersection of the arc and line .
Step 6: Draw an arc so it intersects the bottom of the arc. Label the intersection D.
Step 7: Use a straightedge to connect points E and D to form the parallel line .
so the answer is Place the point of the compass on C and draw an arc that crosses both lines
