The group with the greatest percent of students is expected to be the one with grades between 70 and 80 (inclusive), since this is close to the mean of 75 and encompasses approximately 68% of the data in a normal distribution (according to the empirical rule).
The empirical rule states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations, and approximately 99.7% falls within three standard deviations.
So, in this case, grades between 70 and 80 (75 - 5 and 75 + 5) would contain approximately 68% of the students in the course.

7 = x + 12 helllllllllllllpppppppppppppppp plllsssssssssssssss
Answer: -5
Step-by-step explanation:
To solve for x, you must use inverse operations.
We must move the 12 from the right, to the left in order to solve for x.
The inverse of addition, is subtraction.
Subtract 12 from both sides
7 - 12 = x + 12 - 12
To subtract a bigger number from a smaller number, flip it around, and make your answer negative
12 - 7 = 5
7 - 12 = -5
Something minus itself is 0
-5 = x + 12 - 12
-5 = x + 0
We like to have x on the left, and the = is symetrical. Just flip it around
x = -5 + 0
x = -5
Verify
7 = -5 + 12
7 = 12 - 5
7 = 7

Suppose that an ordinary deck of 52 cards (which contains 4 aces) is randomly divided into 4 hands of 13 cards each. we are interested in determining p, the probability that each hand has an ace. Let E, be the event that the ith hand has exactly one ace. Find p = P(EE, ESE) by using the multiplication rule.
Probability of having exactly one ace in each hand of 13 cards can be found by using the multiplication rule: p = P(E1)P(E2)P(E3)P(E4), where E1, E2, E3, and E4 represent events of having exactly one ace in each hand.
The probability that the first hand has exactly one ace and the second hand has exactly one ace and the third hand has exactly one ace can be calculated as follows:
p = (4/52) * (3/51) * (4/50) * (3/49) = 6/54145.
The probability of an event happening is represented as P(E), where E is the event. The multiplication rule states that if two events are independent and mutually exclusive, then the probability of both events happening is equal to the product of their individual probabilities. In this case, we have three events E1, E2 and E3, where each event is that a hand has exactly one ace. To find the probability of all three events happening, we use the multiplication rule as P(E1 and E2 and E3) = P(E1) * P(E2|E1) * P(E3|E1 and E2), where P(E2|E1) and P(E3|E1 and E2) are the conditional probabilities of E2 and E3 given that E1 has happened.

On saturday, the ratio of the amount of water sued by Household A to the amount of water used by Household B is 13:5. Household A uses 975 litres of water. Determine the total amount of water used by the two households on Saturday.
Answer:
1350
Step-by-step explanation:
A:B = 13:5 = 975:x
x=975/13*5 =375
total =975+375 = 1350
We use the proportional method
Let A = water used in household A.
Let B = water used in household B.
A to B = 13 to 5
A = 260 gal
260 to B = 13 to 5
260/B = 13/5
13B = 5 * 260
B = 100
A + B = 260 + 100 = 360
The total is 360 gallons.

Step 2 : Explanation
Box plots are a graphical tool used in statistics to show the concentration of data. They also demonstrate how far the extreme numbers differ from the majority of the data. The smallest value, the first quartile, the median, the third quartile, and the maximum value are used to create a box plot.
Use a horizontal or vertical number line and a rectangular box to make a box plot. The axis's ends are labelled by the smallest and largest data values. One end of the box is marked by the first quartile, while the other end is marked by the third quartile. Approximately half of the data is included within the box. From the box's ends to the smallest and greatest data values, the "whiskers" extend. The median or second quartile can be in the middle of the first and third quartiles, or it can be either one or the other.

create a universal conditional statement in the domain of square roots of positive integers that is vacuously true. [a conditional is vacuously true if, and only if, the truth set of the hypothesis is empty.] g
A vacuously true statement in the domain of square roots of positive integers is: For any integer x, if x is not a perfect square, then the square root of x is not an integer.
This statement is vacuously true because the truth set of the hypothesis (x is not a perfect square) is empty; there are no positive integers which are not perfect squares.
For example, the perfect squares of the first 10 positive integers are 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100. Thus, the hypothesis (x is not a perfect square) is false for any x from 1 to 10. Therefore, the statement is vacuously true.
Formula:
Let x be any positive integer
Vacuously true statement:
If x is not a perfect square, then the square root of x is not an integer.
For any positive integer x, since x is not a perfect square, the square root of x is not an integer.

The measurement scale for "age in years" is ordinal, meaning the values have a specific order or ranking, but no notion of equal distances between them.
The "age in years" measurement scale is ordinal. An ordinal scale is a type of measurement scale that has a specific order or ranking to its values, but there is no notion of equal distances between the values. In the case of "age in years," the values have a clear order (e.g., 25 years old is younger than 30 years old), but it doesn't make sense to say that a difference of 5 years is the same as a difference of 1 year. This is why age in years is considered to be measured on an ordinal scale.
Additionally, with an ordinal scale, the values can only be compared in terms of their order or ranking, and not in terms of the actual differences between them. For example, we can say that someone who is 25 years old is younger than someone who is 30 years old, but we cannot say that a person who is half as old as someone who is 50 years old at the age of 25. This is because an ordinal scale does not have a meaningful zero point and does not allow for meaningful comparisons of the absolute size of differences between values. An ordinal scale is the second highest measurement scale, below interval and ratio scales, which provide more information about the magnitude of the values being measured.

c. Use this information to estimate the elevation of the Mississippi 11 miles from its source.
a)
g(10) = 62 means at 10 miles from the source, the elevation of the Mississippi river is 62 feet.
b)
The rate of change of the elevation with distance from the source is -2.4.
c)
The elevation of the Mississippi 11 miles from its source is 59.6 feet.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
g(x) is the elevation in feet of the Mississippi river x miles from its source.
a)
g(10) = 62
This means,
At 10 miles from the source, the elevation of the Mississippi river is 62 feet.
b)
g'(10 = -2.4
This means,
The rate of change of the elevation with distance from the source is -2.4.
It is negative because the river flows downward.
The unit is feet per mile.
c)
We can make g(x) = mx + c
m = -2.4
(10 , 62) = (x, g(x))
So,
62 = -2.4 x 10 + c
62 = -24 + c
c = 62 + 24
c = 86
And,
g(x) = -2.4x + 86
So,
At x = 11 miles
g(11) = -2.4 x 11 + 86
g(11) = -26.4 + 86
g(11) = 59.6
Thus,
g(10) = 62 means at 10 miles from the source, the elevation of the Mississippi river is 62 feet.
The rate of change is -2.4.
The elevation of the Mississippi 11 miles from its source is 59.6 feet.

An appropriate interpretation of the 95 percent confidence level is Approximately 95% of all farm sizes in the United States are between 367 acres and 558 acres.
Random sampling is a method of choosing a sample of observations from a population to make assumptions about the population. It is also called probability sampling. The counterpart of this sampling is non-probability sampling or Non-random sampling. The primary types of this sampling are simple random sampling, stratified sampling, cluster sampling, and multistage sampling. In the sampling methods, samples which are not arbitrary are typically called convenience samples.
The primary feature of probability sampling is that the choice of observations must occur in a ‘random’ way such that they do not differ in any significant way from observations, which are not sampled.

The researcher could then compare the effectiveness of the other treatment groups to the control group and determine which treatment is most effective for treating insomnia.
The researcher would utilize the following formula to calculate the effectiveness of the different insomnia treatments:
Effectiveness = (Average Hours Slept in Treatment Group - Average Hours Slept in Control Group) / Average Hours Slept in Control Grou
For example, if the average hours slept in the treatment group is 8 hours and the average hours slept in the control group is 6 hours, then the effectiveness follows:
Effectiveness = (8-6) / 6 = 0.33 or 33%

(40 POINTS) The area of the right triangle shown below is 200 ft^2. The segment XY has a length of 10 ft. Find the length of the hypotenuse. Round to the tenths place if necessary. Show or explain your work. (40 POINTS)
The length of the hypotenuse is given as follows:
41.23 ft.
How to obtain the length of the hypotenuse?The Pythagorean Theorem states that for a right triangle, the length of the hypotenuse squared is equals to the sum of the squared lengths of the sides of the triangle.
The features of the right triangle in this problem are given as follows:
Side lengths of 10 and x.Hypotenuse of h.Area of 200 ft².The area of a right triangle is given by half the multiplication of the two side lengths of the triangles, hence the length x is given as follows:
0.5 x 10x = 200
5x = 200
x = 200/5
x = 40 ft.
Now we have the side lengths, the Pythagorean Theorem is applied to obtain the hypotenuse length, as follows:
h² = 10² + 40²
h = sqrt(10² + 40²)
h = 41.23 ft.

based on the table, do the data support the use of a normal model to approximate population characteristics?
Yes, as the relative frequency distribution closely resembles the empirical criterion for normal models.
Frequency tables or charts are used to represent frequency distributions. Frequency distributions can display the proportion of observations or the actual number of observations that fall inside each range. The distribution is known as a relative frequency distribution in the latter case.
What is the relative frequency distribution formula?
Subgroup Count / Total Count: Relative Frequency
Because they let us determine how frequent a certain value is in a dataset in comparison to all other values, relative frequency distributions are helpful.

these are the dimensions for Angel is planning on painting his room with a beautiful deep blue over the holidays. Mom has strict rules about not getting any paint on the ceilings and floors, so he must be very careful. His room also has two windows and a door that he won't be painting. What is the total amount of space he will be covering with blue if the windows are 12 square feet each, and his door is 16 square feet?
Answer:
420 ft²
Step-by-step explanation:
The front and back walls have length 15 ft and height 10 ft.
The right and left walls have length 8 ft and height 10 ft.
There are two windows with 12 ft² each.
There is a door with 16 ft².
total area to paint = area of 4 walls - area of windows - area of door
A = 2(15 ft × 10 ft) + 2(8 ft × 10 ft) - 2(12 ft²) - 16 ft²
A = 300 ft² + 160 ft² - 24 ft² - 16 ft²
A = 420 ft²
