Answer:
The distribution is skewed (either to the left or to the right).
Step-by-step explanation:
Skewness is the measure of how symmetric the distribution of the data is around its mean. It can be skewed either to the left or to the right (meaning that one of the "tails" of the distribution is longer than the other). This means that the mass your data set's observations tends to accumulate more around one extreme of the distribution than around the other.
A strictly symmetric, normal distribution would have a skewness measure of 0.

You deposit $5000 in an account earning 7.5% simple interest. How long will it take for the balance of the account to be $6500?
Final answer:
It will take 4 years for the balance of an account to grow from $5000 to $6500 at a 7.5% simple interest rate. The formula for simple interest I = P × r × t is used, and after rearranging to solve for t, we find t = 4 years.
Explanation:
To calculate how long it will take for the balance of an account to reach a certain amount with simple interest, we can use the formula for simple interest: I = P × r × t, where I is the interest earned, P is the principal amount (initial deposit), r is the annual interest rate, and t is the time in years. In this case, we want to find out when the account balance will be $6500 after depositing $5000. The total interest earned to reach $6500 will be $6500 - $5000 = $1500.
The given annual interest rate is 7.5% (or 0.075 when converted to decimal form). We will rearrange the simple interest formula to solve for t:
t = I / (P × r)
Now, substituting the given values:
t = $1500 / ($5000 × 0.075)
t = $1500 / $375
t = 4 years
Therefore, it will take 4 years for the balance of the account to be $6500 at a 7.5% simple interest rate.
A golfer has 4 different hats, 3 gloves, and 2 pairs of shoes to pick from for his round of golf. In how many ways can he make his choices?
The number of ways the golfer can make his choices is 4 hats times 3 gloves times 2 shoes, resulting in 24 different combinations.
Explanation:The student is asking about the number of different ways a golfer can choose from 4 hats, 3 gloves, and 2 pairs of shoes. To find the total number of combinations, we multiply the number of choices for each category. Thus, the number of ways the golfer can make his choices is:
4 (hats) × 3 (gloves) × 2 (shoes) = 24 combinations.
This is not an instance where factorial calculation (4!) is necessary, since the golfer does not need to select one of each item in a specific order but simply needs to choose one from each category.
To calculate the number of ways the golfer can make his choices, we can use the concept of permutations.
For the hats, there are 4 choices. For the gloves, there are 3 choices. And for the shoes, there are 2 choices.
To find the total number of combinations, we multiply the number of choices for each category together: 4 hats * 3 gloves * 2 pairs of shoes = 24 different ways the golfer can make his choices.
Final answer:
The golfer can choose his accessories in 24 different ways by selecting 1 out of 4 hats, 1 out of 3 gloves, and 1 out of 2 pairs of shoes, and multiplying the choices together (4 × 3 × 2).
Explanation:
The question asks us to calculate the total number of ways the golfer can choose his outfit accessories assuming he chooses one of each type. To do this, we need to consider each type of accessory independently and multiply the number of choices for each type.
The golfer has 4 different hats, 3 pairs of gloves, and 2 pairs of shoes to choose from. Since these choices are independent of each other, we simply multiply the number of options for each type of accessory:
4 options for hats,3 options for gloves,2 options for shoes.Thus, the total number of combinations is 4 hats × 3 gloves × 2 shoes = 24 different ways the golfer can choose his accessories for the round of golf.
This is an example of a fundamental counting principle problem, where we multiply the number of choices in each step to get the total number of combinations.
Ms. johnson's class is having a pizza party. if there are 14 students and 7 pizzas cut into 8 slices, what answer choice represents the fraction of one pizza that each student receives?
We are asked about the fraction of pizza each student gets, so the relevant numbers here is only 14 students and 7 pizzas. SO the fraction of pizza each student get is the ratio of the two:
fraction = 7 pizzas / 14 students
fraction = 1 / 2
So each student gets 1/2
Each student receives 4 slices out of 8, or half a pizza, which is represented by the fraction 1/2. There are 56 slices available in total (7 pizzas times 8 slices each), and when that is divided by 14 students, it equals 4 slices per student.
The question asks for the fraction of one pizza that each student receives at a pizza party. Given that there are 14 students and 7 pizzas, each pizza is cut into 8 slices. This information can be used to calculate the total number of slices available and then divide that by the number of students to determine the fraction of a pizza each student gets.
First, we find the total number of slices by multiplying the number of pizzas by the number of slices per pizza:
7 pizzas x 8 slices per pizza = 56 slices
Next, we divide the total number of slices by the number of students to find how many slices each student will receive:
56 slices ÷ 14 students = 4 slices per student
Since each pizza has 8 slices, 4 slices represent half a pizza. Therefore, the fraction of one pizza that each student receives is 1/2.

A car is traveling at a rate of 50 miles per hour. what is the car's rate in kilometers per hour? how many kilometers will the car travel in 3 hours? in your computations, assume that 1 mile is equal to 1.6 kilometers.
Final answer:
To convert 50 miles per hour to kilometers per hour, multiply by 1.6 to get 80 km/h. In 3 hours, the car will travel 240 kilometers.
Explanation:
The student is asking how to convert a car's speed from miles per hour (mi/h) to kilometers per hour (km/h), and then calculate the distance traveled in kilometers over a period of 3 hours.
Conversion from mi/h to km/h
To convert the car's speed from miles per hour to kilometers per hour, you can use the conversion factor that 1 mile is equal to 1.6 kilometers. Given the car's speed of 50 miles per hour, the calculation would be:
Speed in km/h = Speed in mi/h imes Conversion factor = 50 mi/h imes 1.6 km/mi = 80 km/h.
Distance Traveled in 3 Hours
Now, to compute the distance the car will travel in 3 hours at 80 km/h, use the formula:
Distance = Speed imes Time = 80 km/h imes 3 h = 240 kilometers.
We’ve seen that natural numbers are closed under addition. Determine the closure of natural numbers under the other three operations, and give examples to support your answers.
Natural numbers are closed under multiplication but not under subtraction and division: subtracting or dividing two natural numbers can lead to results that aren't natural numbers (negative numbers or fractions, respectively).
Explanation:The student's question pertains to the closure of natural numbers under the operations of subtraction, multiplication, and division. Natural numbers are numbers used for counting and ordering that include all positive integers from 1 onwards. Let's evaluate each of these operations with respect to closure:
Subtraction: Natural numbers are not closed under subtraction because subtracting a larger number from a smaller one results in negative numbers, which are not part of the natural numbers. For example, 3 - 5 = -2 is not a natural number.
Multiplication: Natural numbers are closed under multiplication because the product of any two natural numbers is always a natural number. For example, 2 x 3 = 6, and both the numbers and result are natural numbers.
Division: Natural numbers are not closed under division because the division of two natural numbers can result in a fraction or a decimal that is not a natural number. For example, 1 / 2 = 0.5, which is not a natural number.
When a natural number is subtracted or divided by another, the result might not always be a natural number, indicating that natural numbers are not closed under these operations.
The closure property holds for addition and multiplication of natural numbers, but not for subtraction and division.
Explanation:Addition:The closure property states that when you add two natural numbers, the result is always a natural number. For example, 2 + 3 = 5.
Subtraction:Subtraction is not closed under natural numbers. For example, if you subtract 3 from 2, you get -1, which is not a natural number.
Multiplication:The closure property holds for multiplication as well. When you multiply two natural numbers, the result is always a natural number. For example, 2 x 3 = 6.
Division:Division is not closed under natural numbers. For example, 2 ÷ 3 = 0.67, which is not a natural number.

[tex]\Rightarrow (x-3)^2[/tex]
[tex]\Rightarrow (x-3)(x-3)[/tex]
Hence, The factor of given polynomial is [tex]\Rightarrow (x-3)(x-3)[/tex]
Factorizing the polynomial expression x² - 6x + 9 = (x - 3)²
What is factorization?Factorization is the simplification of an expression into a smaller expression using its factors.
To factor the polynomial expression. x² - 6x + 9, we proceed as follows
Since we have the polynomial expression x² - 6x + 9, we multiply x² by 9 to get x² × 9 = 9x².
Now, we desire to find the factors of 9x² so that the sum of those factors equal - 6x
Thus, we have 9x² = -3x × (-3x)
So, -6x = -3x - 3x
Thus, we replace this with -6x, so
x² - 6x + 9 = x² - 3x - 3x + 9
So, factorizing, we have that
x² - 3x - 3x + 9 = x(x - 3) - 3(x - 3)
= (x - 3)(x - 3)
= (x - 3)²
So, factorizing x² - 18x + 81 = (x - 9)²

What is the area of rhombus ABCD ?
Enter your answer in the box. Do not round at any steps.
Answer:
16 units
Step-by-step explanation:
The area of a rhombus is given by the formula A = bh. The base would be CB and the height would be DP. We will use the distance formula to find the length of each:
[tex]d=\sqrt{y_2-y_1)^2+(x_2-x_1)^2}[/tex]
For CB, we have
[tex]d=\sqrt{(2-0)^2+(3--1)^2}=\sqrt{2^2+4^2}=\sqrt{4+16}=\sqrt{20}[/tex]
For DP we have
[tex]d=\sqrt{(2--1.2)^2+(-5--3.4)^2}=\sqrt{3.2^2+1.6^2}=\sqrt{10.24+2.56}=\sqrt{12.8}[/tex]
This makes the area of the rhombus
[tex]A=bh=\sqrt{20}\times \sqrt{12.8}=\sqrt{20\times 12.8}=\sqrt{256}=16[/tex]
The area of a rhombus can be found using the formula (diagonal1 * diagonal2) / 2. In this case, the area is 24 cm^2.
Explanation:The area of a rhombus can be found using the formula:
Area = (diagonal1 * diagonal2) / 2
where diagonal1 and diagonal2 are the lengths of the two diagonals of the rhombus.
For example, if diagonal1 = 6 cm and diagonal2 = 8 cm, the area of the rhombus is:
Area = (6 * 8) / 2 = 24 cm2
Therefore, the area of rhombus ABCD is 24 cm2.

Line segment ab has a length of 4 units. it is translated 1 unit to the right on a coordinate plane to obtain line segment a prime b prime. what is the length of a prime b prime? 1 unit 4 units 5 units 6 units
Answer:
The length of A'B' is 4 unit.
Step-by-step explanation:
Translation is a rigid transformation in which a figure or a line segment is shifted or moved without changing its shape and size,
That is, if the measurement of segment AB is 4 unit then after translation by any factor its measurement will not change,
So, the measurement of segment A'B' would be 4 unit.
Verification :
Let the coordinates of A and B are [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] respectively,
Also, the rule of translation 1 unit right is,
[tex](x,y)\rightarrow (x+1, y)[/tex]
By the distance formula,
The measure of segment AB = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Thus, if A'B' is the transformed segment of segment AB,
Then, coordinates of A' and B' are [tex](x_1+1, y_1)[/tex] and [tex](x_2+1, y_2)[/tex]
So, the measure of segment A'B' = [tex]\sqrt{(x_2+1-x_1-1)^2+(y_2-y_1)^2}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Hence, the measure of AB = measure of A'B'

angle b = arctan(7/5) = 54.5
Answer is C
Answer:
(C)35.5° and 54.5°
Step-by-step explanation:
It is given that ABC is a right angled triangle which is right angled at C and AC=7 inches and CB=5 inches.
Now, using the trigonometry, we have
From ΔABC, we have
[tex]\frac{BC}{AC}=tanA[/tex]
[tex]\frac{5}{7}=tanA[/tex]
[tex]0.714=tanA[/tex]
[tex]A=tan^{-1}(0.714)[/tex]
[tex]A=35.5^{\circ}[/tex]
Again, from ΔABC, we have
[tex]\frac{AC}{BC}=tanB[/tex]
[tex]\frac{7}{5}=tanB[/tex]
[tex]1.4=tanB[/tex]
[tex]B=tan^{-1}(1.4)[/tex]
[tex]B=54.5^{\circ}[/tex]
Therefore, the measure of missing angles in triangle ABC are 35.5° and 54.5°respectively.
Thus, option C is correct.
