a fair six-sided die with sides labeled 1 through 6 is rolled. quantity a quantity b the probability that the number rolled is closer to 4 than it is to 2 the probability that the number rolled is closer to 5 than it is to 3
On solving the provided question, we can say that probability that a four or higher number will first emerge on the third or fourth roll.= 4/27 + 8/81 = 20/21
What is probability?Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.
On a dice, the numbers 5 and 6 are the ones above 4. The likelihood of receiving a number higher than 4 (i.e., 5 or 6) is = 2/6 = 1/3
and as a result, the likelihood of receiving 4 or less is= 1-1/3 = 2/3
The likelihood that a number larger than 4 will show up on the third roll is equal to
2/3* 2/3 * 1/3 = 4/27
The likelihood that a number larger than 4 will emerge on the fourth roll is equal to =2/3*2/3* 2/3 * 1/3 = 8/81
probability that a four or higher number will first emerge on the third or fourth roll.= 4/27 + 8/81 = 20/21

A coordinate graph is shown with an upward sloped line crossing the y axis at the origin that ends at the open point 3, 1, a closed point at 3, 7, and a horizontal line starting at the open point 3, 3.
Find limit as x approaches three from the left of f of x..
The limit of f(x) as x approaches 3 does not exist, as the lateral limits are different.
How to calculate the limit of a function?The first step in calculating the limit of a function is calculating the numeric value of the function at the value of x which the function approaches.
On the graph of a function, the limit of f(x) as x approaches a value of a is defined considering it's lateral limits, that is:
Limit as x approaches a to the left.Limit as x approaches a to the right.If the lateral limits are different, then the limit does not exist.
To the left of x = 3, the line ends at point (3,1), hence the lateral limit to the left of x = 3 is given as follows:

Coins are placed into a treasure chest, and each coin has a radius of 1.4 inches and a height of 0.0625 inches. If there are 230 coins inside the treasure chest, how many cubic inches of the treasure chest is taken up by the coins? Round to the nearest hundredth and approximate using π = 3.14.
0.38 in3
126.39 in3
353.88 in3
88.47 in3
Answer:
D. 88.47 in3
Step-by-step explanation:
The volume of a single coin would be the volume of a cylinder with a radius of 1.4 inches and a height of 0.0625 inches. The formula for the volume of a cylinder is V = πr^2h. So, V = 3.14 * (1.4^2) * 0.0625 = 0.38 in^3
Since there are 230 coins, the total volume of the coins would be 230* 0.38 = 87.40 in^3
So, the answer would be 87.40, which is closest to D. 88.47 in3
Answer: D: 88.47 in³
Step-by-step explanation:
So what you want to do is first find the individual volume of the coins. Use the volume formula: V = πr^2h
Take 1.4 and times it by itself
1.4 x 1.4 = 1.96
Now multiply 1.96 by 0.0625
1.96 x 0.0625 = 0.1225
And times 0.1225 by pi, or in this case, 3.14
0.1225 x 3.14 = 0.38465
Now you have found the individual volume of each coin. You are trying to find how much space all of the coins take up together. The question says that there is 230 coins in total. So times 0.38465 by 230 to find how much space all the coins take up.
0.38465 x 230 = 88.4695 in³
Now round it to the nearest hundredth: 88.47 in³
That is your answer.
Also I took the same test and I picked 88.47 inches cubed and got it right.

given the summary statistics below for the size of a sample of automobile engines, show how we can tell there are no outliers in the data set.?
There are a few ways to tell if a dataset contains outliers, one of which is by using summary statistics.
Outliers are data points that fall far outside of the main body of a dataset. They can have a significant impact on the overall summary statistics of a dataset, such as the mean and standard deviation.
Given the summary statistics below for the size of a sample of automobile engines:
Mean: 2.5
Median: 2.5
Mode: 2.5
Standard deviation: 0.5
We can tell that there are no outliers in the data set because the mean, median, and mode are all equal. This indicates that the values in the dataset are tightly clustered around a central value, which is a good indication that there are no outliers. Additionally, the standard deviation is relatively small, which also suggests that the values in the dataset are not spread out very much, again indicating that there are no outliers.
Another approach is using the interquartile range (IQR). This can be calculated by subtracting the 25th percentile (Q1) from the 75th percentile (Q3) of a dataset. Values that fall outside of the range of 1.5*IQR below the first quartile (Q1) or above the 3rd quartile (Q3) are considered outliers.

The number of in-state undergraduates could not be 200.
What is foreign students comprise?International or foreign students are students who migrate to another country to pursue their studies and complete all or a portion of their postsecondary education there.
Each nation has its unique national educational system, which affects how "foreign students" and "international students" are defined.
If foreign students comprise exactly 1/8 of the number of out-of-state undergraduates, then the number of in-state undergraduates would have to be a value that yields an integer value for the number of foreign students.
In-state undergraduates are 55% of 60% of the total, or (.55)(.6) = (.33) of the total.
If 330 is the number of in-state undergraduates, which comprise 33% of the total, then you can calculate the total number of admitted students:
(0.33) (total) = 200
⇒ total = 200/0.33
⇒ total = 200*100/33

Seven times the first number plus six times the second number equals 31. Three times the first number minus ten times the second number is 29.
Answer:
1st number = 5.5
2nd number = -1.25
Step-by-step explanation:
1) 7x + 6y = 31 (multiply entire equation by 3) → 21x + 18y = 93
2) 3x - 10y + 29 (multiply entire equation by 7) → 21x - 70y = 203
3) 21x + 18y = 93
4) -(21x - 70y = 203) now subtract equation (4) from equation (3) to make the x terms drop out
0 + 88y = -110
y = -110/88 = -1.25 now plug this into equation (1) and solve for x
7x + 6(-1.25) = 31
7x = 38.5
x = 38.5/7 = 5.5
is there end behavior for square root function? like for example: [tex]\sqrt{6x}[/tex] or [tex]\sqrt{x-5}-6[/tex]
Answer:
Step-by-step explanation:
Yes, there is an end behavior for a square root function. The end behavior of a square root function is determined by the sign of the leading coefficient of the equation. For example, if the leading coefficient is positive, then the end behavior will be asymptotic to the positive x-axis as x increases, and asymptotic to the negative x-axis as x decreases. Conversely, if the leading coefficient is negative, then the end behavior will be asymptotic to the negative x-axis as x increases, and asymptotic to the positive x-axis as x decreases.

The vertex of the quadratic equation:
f(x) = 2x^2 - 8
is (0, -8)
How to find the vertex of the quadratic equation?For a general quadratic equation:
a*x^2 + b*x + c
The vertex is located at the x-value:
x = -b/2a
Here we have the quadratic equation:
f(x) = 2x^2 - 8
Then the values are:
a = 2
b = 0
c = -8
Then the vertex is at:
x = 0/2*2 = 0
To get the y-value of the vertex, we need to evaluate on x = 0.
f(0) = 2*0^2 - 8 = -8
So the vertex is (0, -8).

Unit conversion is a process with multiple steps that involves multiplication or division by a numerical factor or, particularly a conversion factor. The process may also require selection of the correct number of significant digits, and rounding. Different units of conversion are used to measure different parameters. By definition conversion of units means the conversion between different units and measurements of the same quantity done by the process of multiplication or division. In maths, conversion is the process of changing the value of one form to another for example inches to millimeters, or liters to gallons. Units are used for measuring length, measuring weight, measuring capacity, measuring temperature, and measuring speed.
If we want to calculate how many Grams are 1000 Milligrams we have to multiply 1000 by 1 and divide the product by 1000. So for 1000, we have (1000 × 1) ÷ 1000 = 1000 ÷ 1000 = 1 Gram.
So finally 1000 mg = 1 g
Thus, converting 1,000 mg to 1 gram would require moving the decimal place zero places to the left.
