Which Step In The Solution Contains The First Error?

Answers

Answer 1

9514 1404 393

Answer:

  Step 4

Step-by-step explanation:

In Step 1, the first equation is correctly multiplied by 2.

In Step 2, the two equations from step 1 are correctly added.

In Step 3, the value of x is correctly determined by dividing by 11.

In Step 4, the value of x is incorrectly substituted for y in the original first equation.

The first error is in Step 4.

Ratio of fruit to nuts in the first bag:3 5 Ratio of fruit to nuts in the second bag:7 10 Which bag has more fruit? Use the ratios to justify your answer. The first bag, because the ratio is greater. The first bag, because the ratio is smaller. The second bag, because the ratio is greater. The second bag, because the ratio is smaller.

Answers

Answer:

the second bag because the ratio is greater

Step-by-step explanation:

Bag1

fruits 3 : 5 nuts so 3+5=8 and 60/8=7.5 but 7.5*3=22.5

ratio is 3/5=0.428

Bag2

fruits 7 : 10 nuts so 10+7=17 and (60/17)*7 ≈ 24.7

ratio is 7/10=0.7

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.

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?

Answers

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?

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? ​

Answers

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:

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?

Answers

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.

y>-3x+1

How do I graph this

Answers

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

120. Hope this helps have a good day.

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.
