geometry!! can someone help me with #23 please? it would mean a lot thanks :)
Answer:
yes, they are parallel lines in #23
Step-by-step explanation:
the slope of both lines is -1
y>-3x+1
How do I graph this
Answer:
The graph of y>-3x+1 through the points (0,1) and (1,-2)
Step-by-step explanation:
y=3x+1 is in the slope intercept form
y=mx+b
m = the slope in this case 3
b = the y intercept in this case 1.
Think of b the y intercept as the beginning this is where to start the graph.
So start with (0,1) the y intercept and make the first point at (0,1)
Think of m ( the slope) as the mountain slope, This is the angle of the slope of the line
So in this case go up three on the y axis and over 1 on the x axis.
make the next point at 1 + 3 = 4 for the y value and 0 + 1 = 1 for the x value. Make the next point at ( 1, 4)
Now connect the points. creating the line

A class of 63 students is going on a field trip. They will take 9 buses. Each bus will have the same number of students. How many students will be on each bus?
Answer:
There will be 7 students on each bus.
Step-by-step explanation:
If the class of 63 students is divided into 9 buses with the same number of students traveling in each one, to determine the number of students traveling in each bus it is necessary to perform the following mathematical calculation:
63/9 = X
7 = X
Thus, in each bus 7 students will travel, and in this way all buses will carry the same number of students.
Answer:
9
Step-by-step explanation:
36 divided by 4 = 9

What is the 2nd step in solving this problem x/4 - 3 = 12 ?
A. Do the inverse by adding 3 to both sides
B. Do the inverse by dividing both sides by 4
C. Subtract 3 on both sides
D. Multiply by 4 on both sides
Answer:
A
Step-by-step explanation:
After the first step, which is to do the inverse by dividing both sides by 4.
The equation will look like x-3=48
You the have to do the second step, which is to add 3 (or do the inverse) on both sides (answer A)

5(4 • 3 + 3 • 4)=
480
300
120
Answer:
Step-by-step explanation:
Our given equation is 5 (4 × 3 + 3 × 4)
Using The Order of Operations (AKA): PEMDAS, we need to solve this.
The "P" stands for parentheses. We do have them, so we need to solve the operations inside of them.
We don't have any parentheses inside.
The "E" stands for exponents. We don't have any, so we need to move on.
The "M" stands for multiplication. We have two multiplication symbols, so we need to solve them.
1. 5 (4 × 3 + 3 × 4)
2. 5 (12 + 3 × 4)
3. 5 (12 + 12)
The "D" stands for division. We don't have any of them, so we need to move on.
The "A" stands for addition. We have one of them, so we need to solve.
4. 5 (12 + 12)
5. 5 × 24
Now that we only have the operation 5 × 24, we can go ahead and solve.
6. 5 × 24 = 120
So now we know that when using The Order of Operations to solve the equation: 5 (4 × 3 + 3 × 4) results in a 120.
Remember this; This is The Order of Operations/ PEMDAS expression:
P arentheses
E xponents
M ultiplication

Do the Louisiana State Flag have a line of symmetry?
Answer: No it does not
Well, first you can search up a picture of the Louisiana State Flag if you don't know what it looks like. In case you don't, it looks like this.
The Louisiana State Flag does not have a line of symmetry because the bird's head is facing in one direction. If you split the state flag in half, both sides would not be similar.
please help asap, will mark brainliest

The y-intercept of an equation is a point where the graph of the equation intersects the Y-axis. There are several ways to find the y-intercept of an equation, depending on the starting information you have.
How to find the Y-Intercept from the Slope and Point.
Write down the slope and point. The slope or "rise over run" is a single number that tells you how steep the line is. This type of problem also gives you the (x, y) coordinate of one point along the graph. Skip to the other methods below if you don't have both these pieces of information.
Example 1: A straight line with slope 2 contains the point (-3,4). Find the y-intercept of this line using the steps below.Pleaseee drop answers !!!’

N is a product of two primes. N is prime, composite or special number?
Answer:
special number
Step-by-step explanation:
Answer:
The answer is a composite number Step-by-step explanation: If you multiply 3x3, that is 9, which is composite. Even if you go forever trying to multiply a prime number by a prime number, it will always be composite.
What makes a function of a discrete variable a candidate for a discrete random variable distribution? What about the counterpart of this candidacy in the case of a continuous variable?
Answer and Step-by-step explanation:
A random variable is a variable having numerical values determined by the outcomes of the experiment. A random variable may have a finite number or an infinite sequence of values said to be discrete.
A random variable that describes the number of automobiles sold at a dealership would be discrete one day. Simultaneously, a random variable represents the weight of a person in a kilogram or pounds.
The probability distribution of discrete random variable x is each possible value of x and the probability that x takes amount in one trial of the experiment.
The probability distribution of the random variable contains the following properties:
1- Each probability must be between 0 and 1.
0 ≤ p(x) ≤ 1
2- The sum of all probabilities is equal to 1.
Ʃp(x) = 1
A continuous random variable may assume any value from data. The continuous random variable takes costs that vary within one or more intervals. And it has a cumulative distribution function (CDF) that is absolutely continuous.
The random variable has an infinite number of possible values, which have zero probability. The range of this type of discount can have a nonzero chance.
The probability distribution of the random variable is described by probability density, where the probability can be calculated by taking the area under the curve.

Erik Red is a player for the Arizona Snowflakes in the National Foosball League. The league has 25 teams, each with 73 players. Every week, 8 players per team are chosen for random drug testing.
A) What is the probability that Erik Red is chosen for random drug testing in a specified week of the foosball season?
B) What is the probability that Erik Red is chosen for random drug testing at least 5 times in the first 9 weeks of the foosball season?
C) What is the expected number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season?
D) Let Y be the number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season. What is the maximum possible value of Y, i.e., the largest k such that P(Y=k) > 0?
Answer:
8/73
0.10959
21 players
Step-by-step explanation:
Given that:
Number of teams = 25
Number of players per team = 73
Number of players chosen for drug testing = 8
A) What is the probability that Erik Red is chosen for random drug testing in a specified week of the foosball season?
Number chosen per team / number of players per team
8 / 73 = 0.10959
B) What is the probability that Erik Red is chosen for random drug testing at least 5 times in the first 9 weeks of the foosball season?
P( being chosen at least 5 times)
USing binomial. Distribution
P(X =x) = nCr * p^x * (1-p)^n-x
To save computation time, we can use the binomial distribution calculator :
P(x≥5):p(x = 5) + p(x = 6) + p(x =7) + p(x = 8) +. P(x = 9) = 0.00136
C) What is the expected number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season?
Number who are chosen atleast 4 times :
P(x ≥ 4) = p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7) + p(x = 8) +. P(x =9) = 0.0115
P(x ≥ 4) * number of players per team * nunber of teams in league
0.0115 * 73 * 25 = 20.9875
= 21 players
D) Let Y be the number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season. What is the maximum possible value of Y, i.e., the largest k such that P(Y=k) > 0?
