Jack rolled a die 60 times and recorded the results in the table.
What could Jack expect to happen to the probability of getting a four if he increased the number of trials to 450?
A)Jack has no idea what to expect. Until you actually perform the simulation you cannot predict the outcome of the results.
B)Jack should see the experimental probability of getting a four to decrease and come closer to 0.167 due to the Law of Large Numbers.
C)Jack should expect to see a increase in the probability of getting a four. As you increase the number of trials you increase the number of times a four occurred, which raises the probability.
D)Jack should expect to see the probability of getting a four remain the same. If you increase the number of trials you can expect to see similar results as to what you got the first time, therefore the probability will not change.
Answers
Answer:
C
Step-by-step explanation:
The number of times it happens the more Fours will occur
The correct option is Jack should see the experimental probability of getting a four to decrease and come closer to 0.167 due to the Law of Large Numbers.
What is probability?
A probability is a number that reflects the chance or likelihood that a particular event will occur.
Given that, Jack rolled a die 60 times, and then he increased the number of trials to 450
The law of large numbers;
The law of large numbers indicates that if an event of probability p is observed repeatedly during independent repetitions, the ratio of the observed frequency of that event to the total number of repetitions approaches p as the number of repetitions becomes arbitrarily large.
Hence, Jack should see the experimental probability of getting a four to decrease and come closer to 0.167 due to the Law of Large Numbers, is the correct answer.

Answer:
$292.50
Step-by-step explanation:
Equation - A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2.5%/100 = 0.025 per year.
Solving our equation:
A = 260(1 + (0.025 × 5)) = 292.5
A = $292.50
The total amount accrued, principal plus interest, from simple interest on a principal of $260.00 at a rate of 2.5% per year for 5 years is $292.50.

y=3x-4 is the slope-intercept form of the equation of a line. It is in the form y=mx+b.
m is the slope (often called "rise over run") and b is the y-intercept (the point where x=0).
The y-intercept is the point (0,-4).
We need one other point. This is where finding easy calculations pays off. How about where x=2, y=(3)(2)-4 = 2.

Part I: Making the Race
Henri is Emile's younger brother and they are having a walking race. Emile can walk 2.5 meters per second whereas Henri walks 1 meter per second. Because Emile is faster, they give Henri a 45 meter head start. Emile knows Henri would enjoy winning the race, but they do not want to make the race so short that it is obvious Emile let Henri win.
1. How long should the race be so that Henri will win in a close race?
2. Describe or show your strategy on how you came up with your answer for #1.
Answers
74 meters
Step-by-step explanation:
The difference in Emile and Henry's speed is 1.5, and the lead for Henry is 45 meters, so 45÷1.5= 30 seconds which means Henry will go another 30 meters at 1 meter per second.
2. To make it a close race we want Henry to go a longer distance than Emile, so make it 74 meters, which means Emile will go only have 45+29 = 74 seconds to get to 74 meters, but Henry only have 29 seconds in total = 29*2.5 = 72.5 meters.

Describe the pros and the cons of using the standard form of a line to graph an equation.
Answers
Answer:
The standard form of a line is expressed as Ax + By = C, where A, B, and C are constants and x and y represent the variables. One advantage of using the standard form to graph a line is that it is relatively easy to determine the slope and y-intercept of the line from the constants A and B. This can be particularly useful when trying to analyze the behavior of the line.
Another advantage of using the standard form is that it allows you to easily determine the equation of the line when given a set of points. For example, if you are given the points (2,4) and (3,6), you can use the standard form to find the equation of the line that passes through these points by substituting the coordinates into the form and solving for the constants.
One potential disadvantage of using the standard form is that it can be more difficult to interpret the meaning of the constants A, B, and C in terms of the context of the problem. For example, if the line represents the cost of a product, it may be more intuitive to express the equation in terms of the variables x (the number of units) and y (the cost). In this case, it may be more useful to use the slope-intercept form of the equation, which is expressed as y = mx + b, where m is the slope and b is the y-intercept.

Determine which integer in the solution set makes this true: 4x -9 = 31 S:{ -10, 5.5, 9, 10}
Answers
Answer: 10
Step-by-step explanation: 4x-9=31
4x=31+9
4x=40
4x/4=40/4
x=10
Answer: 10. 4(10)-9=31
Step-by-step explanation:
firstly, we would substitute the values given in the subset to the value of x and check which solves the equation.
When x= (-10),
4(-10) -9
= -40-9
=-49,
which does not equal 31, so it cannot be -10.
Similarly, when x=5.5,
4(5.5)-9
=22-9
= 13
which does not equal 31.
Thirdly, when x=9
4(9) -9
= 36-9
= 27
which does not equal 31.
Finally,
when x=10,
LHS 4(10)-9
=40-9
=31 RHS
Therefore x=10.

Step-by-step explanation:
Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answers
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.
