Answer: y= -2/3 + 8/3
Step-by-step explanation:
-2/3 is the slope so you just need the y-intercept to write the equation in general form or slope intercept form
4= -2/3(-2) +b
4 = 4/3 + b
-4/3 -4/3
b= 8/3
general form is y= -2/3 + 8/3

b) The 99% confidence interval for the population proportion is given as follows: (0.57, 0.68).
What is a confidence interval of proportions?A confidence interval of proportions has the bounds given by the rule presented as follows:
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which the variables used to calculated these bounds are listed as follows:
\(\pi\) is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of \(\frac{1+0.99}{2} = 0.995\), so the critical value is z = 2.575.
The parameters for this problem are given as follows:
\(n = 520, \pi = \frac{325}{520} = 0.625\)
Then the lower bound of the interval is given as follows:
\(0.625 - 2.575\sqrt{\frac{0.625(0.375)}{520}} = 0.57\)
The upper bound of the interval is given as follows:
\(0.625 + 2.575\sqrt{\frac{0.625(0.375)}{520}} = 0.68\)

(x - 1)(x² + 3x - 4) = x³ + 2x² − 7x + 4
Solving the provided question, we can say that the quadratic equation is \((x - 1)(x^{2} + 3x - 4)\) = \(x^{3} + 2x^{2} - 7x + 4\) and the roots of the polynomial are x = 1, -1, 4.
A quadratic equation is what?A quadratic polynomial in a single variable is represented by the equation \(ax^{2}+bx+c=0\). a 0. Since this polynomial is of second order, the Fundamental Theorem of Algebra guarantees that it has at least one solution. There are both simple and complex solutions.
A quadratic equation is just that—quadratic. It has at least one word that has to be squared, as shown by this. One of the often used solutions for quadratic equations is "ax2 + bx + c = 0." where X is an undefined variable and a, b, and c are numerical coefficients or constants.
the quadratic equation is
\((x - 1)(x^{2} + 3x - 4)\) = \(x^{3} + 2x^{2} - 7x + 4\)
On multiplying,
⇒ \(x (x^{2} + 3x - 4) - (x^{2} + 3x - 4)\)
⇒ \(x^{3} + 3x^{2} - 4x - x^{2} - 3x + 4\)
⇒ \(x^{3} + 2x^{2} - 7x + 4\)
∴ We can say that LHS = RHS.
From given equation, the roots of the equation will be -
\((x - 1)(x^{2} + 3x - 4)\)
⇒ x - 1 = 0
⇒ x = 1
\(x^{2} + 3x - 4 = 0\)
⇒ \(x^{2} - 4x + x - 4\)
⇒ \(x(x - 4) + 1(x - 4)\)
⇒ (x + 1) (x - 4)
⇒ x = -1, x = 4

Answer:
D) 9:20 am
Step-by-step explanation:
Train A's route = 20 mins
Train B's route = 80 mins
80 ÷ 20 = 4
Therefore, Train B's route is 4 times the length of Train A's route.
Therefore, the time Train A and B will leave the station at the same time will be the first time Train B leaves after 8am.
1 hour = 60 minutes
8am + 80 minutes = 8am + 1 hr + 20 minutes = 9:20 am
10. Prime numbers from 1 to 100 are running a restaurant - PRIME SPOT, near a tourist point. On a winter holiday, 1 and the composite numbers up to 100 enter the restaurant for dinner after their picnic at the same point. The dining hall has tables with seating capacity 15 for each. If they occupy tables without leaving any chair free, how many tables are required? If each prime number attender has to serve equal number of customers, how many customers should each one get to serve?
6 tables are required. Each prime number attender should serve 3 customers each.
The prime numbers between 1 and 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
All the numbers other than prime numbers are composite numbers.
The composite numbers from 1 to 100 are: 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.
Now, as there are 25 primes and 75 composites in the group that visited the restaurant, we can calculate the number of tables required by dividing the number of people by the seating capacity of each table.
Each table has a seating capacity of 15, so the number of tables required will be: Number of tables = (Number of customers)/(Seating capacity of each table)Number of customers = 25 (the number of primes) + 75 (the number of composites) = 100Number of tables = 100/15 = 6 tables
Therefore, 6 tables are required.
Now, as each prime number attender has to serve an equal number of customers, we need to calculate how many customers each one should serve.
Each prime attender has to serve 75/25 = 3 customers each, as there are 75 composites and 25 primes.
Thus, each prime number attender should serve 3 customers each.

Put the following equation of a line into slope-intercept form, simplifying all fractions.
2x-12y=12
Answer:
\(y=\frac{1}{6}x-1\)
Step-by-step explanation:
The slope-intercept form is y=mx+b, where m is the slope of the line and b is the y-intercept.
For this problem, the equation can be manipulated into the desired form:
\(2x-12y=12\\2(x-6y)=12\\\frac{2(x-6y)}{2}=\frac{12}{2}\\x-6y=6\\(x-6y)+6y=(6)+6y\\x=6+6y\\x=6(1+y)\\(\frac{1}{6})x=\frac{6(1+y)}{6}\\\frac{1}{6}x=1+y\\(\frac{1}{6}x)-1=(1+y)-1\\y=\frac{1}{6}x-1\)

Enola is saving money and plans on making monthly contributions into an account
earning a monthly interest rate of 0.4%. If Enola would like to end up with $5,000
after 3 years, how much does she need to contribute to the account every month, to
the nearest dollar? Use the following formula to determine your answer.
Enola needs to contribute $4,330.68 per month to the account.
How much does Enola need to contribute to the account?Let's denote the monthly contribution as X.
The interest rate is 0.4% per month.
Since Enola plans to save for 3 years, the total number of months is:
= 3 * 12
= 36 months.
Using formula for compound interest: Future value = Present value * (1 + interest rate)^number of periods
We will plug values:
$5,000 = X * (1 + 0.004)^36
X = $5,000 / (1 + 0.004)^36
X = $5,000 / (1.004)^36
X = $4,330.68248
X = $4,330.68.
the venn diagram shows event a and event b comprised of outcomes from the same sample space. The probability of event A is given, as well as the probability of neither event A nor event B. What is the probability of event B?
A. 0.2
B. 0.4
C. 0.5
D. 0.6
E. 0.8
Answer:
Correct option: D. 0.6
Step-by-step explanation:
The Venn diagram shows that there is no intersection between events A and B, so we have that:
P(A and B) = 0
Therefore the probability of A or B is:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = P(A) + P(B)
So, If the sum of the probabilities needs to be 1, we have that:
Total = P(A or B) + P(neither)
Total = P(A) + P(B) + P(neither)
1 = 0.2 + P(B) + 0.2
P(B) = 1 - 0.2 - 0.2 = 0.6
So the correct option is D.
Answer:0.6
Step-by-step explanation:
There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.
What is the theoretical probability of randomly drawing a red marble?
25%
62.5%
20%
41.7%
Answer:
20%
Step-by-step explanation:
The theoretical probability of drawing a red marble can be found by dividing the number of red marbles by the total number of marbles in the bag:
P(red) = number of red marbles / total number of marbles
P(red) = 5 / (5 + 8 + 12)
P(red) = 5 / 25
P(red) = 0.2
So the theoretical probability of randomly drawing a red marble is 20%, which corresponds to option (C).
Dylan weighs 45 pounds. Use the expression you derived in part I to calculate how much more Bruce weighs than Alan.
Given: 1) weight of Dylan= 45 pounds
2) weight of Alan= 3 pounds more than twice the weight of Dylan
3)weight of Bruce = 12 pounds less than three times the weight of
Dylan.
To Find: How much more does Bruce weighs than Alan .
Solution:
weight of Dylan= 45 pounds
weight of Alan= 3 pounds more than twice the weight of Dylan
= 3 + ( 2×45) pounds
= (3+ 90) pounds
= 93 pounds
weight of Bruce= 12 pounds less than three times the weight of Dylan
= (3× 45) - 12 pounds
= (135) - 12 pounds
= 123 pounds
therefore, the amount by which Bruce weighs more than Alan will be given by:
weight of Bruce - weight of Alan
= 123 pounds - 93 pounds
= 30 pounds
Hence, Bruce weighs 30 pounds more than Alan.

The solution of the equation 4x - 3 = 5 is not extraneous .
How to solve an equation?Extraneous solutions are values that we get when solving equations that aren't really solutions to the equation.
Therefore, let's solve the equation to know whether it is extraneous solution.
Hence,
4x - 3 = 5
add 3 to both sides of the equation
4x - 3 + 3 = 5 + 3
4x = 8
divide both sides of the equation by 4
4x / 4 = 8 / 4
