Explain the steps for dividing decimals. Write three or four sentences.
NO SAMPLE RESPONSE FROM EDGINUTY
Answers
Answer:
Step-by-step explanation:
Move the decimal point in the divisor and dividend.
Turn the divisor (the number you’re dividing by) into a whole number by moving the decimal point all the way to the right. At the same time, move the decimal point in the dividend (the number you’re dividing) the same number of places to the right.
Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend.
Divide as usual, being careful to line up the quotient properly so that the decimal point falls into place.
Line up each digit in the quotient just over the last digit in the dividend used in that cycle.

List the sample space for rolling a fair six-sided die. S = {1} S = {6} S = {1, 2, 3, 4, 5, 6} S = {1, 2, 3, 4, 5, 6, 7, 8}
Answers
Answer:
The sample space for rolling a fair six-sided die is: S = {1, 2, 3, 4, 5, 6}
The sample space represents all the possible outcomes of an event. In this case, the event is rolling a fair six-sided die, so the sample space is the set of all the possible numbers that can appear on the die, which are 1, 2, 3, 4, 5 and 6.
Option A, S = {1}, is incorrect because this only represents one outcome, not all possible outcomes.
Option B, S = {6}, is incorrect because this only represents one outcome, not all possible outcomes.
Option C, S = {1, 2, 3, 4, 5, 6}, is correct as it represents all possible outcomes.
Option D, S = {1, 2, 3, 4, 5, 6, 7, 8}, is incorrect because this includes numbers that cannot appear on a six-sided die, and it does not represent all possible outcomes.

Answers
The probability that a student studied for 5 hours is 0.23 Or 23%.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
A table is given where the first column represents the number of hours a student studied maths and the second column represents the number of students.
The sum of the second column is 30 so it is the total number of students
And only 7 of them studied mathematics for 5 hours.
Therefore, The probability that a student studied for 5 hours is,
= 7/30.
= 0.23 or 23%.

George wrote seven tests and each was marked out of 100. No two of his marks were the same. He recorded the seven marks to do a statistical analysis. He accidentally recorded his highest mark higher than it actually was. How many of the following are altered because of his mistake? 1. Mean 2. Median 3. Minimum test score 4. Range
Answers
Explanation: median isn't affected because it is the middle value of all the values. If the highest score is already at the end of the list, then it won't go up or down if the score is even higher. Minimum isnt affected because that is the lowest score, which has seemingly been entered correctly. Mean is affected because it is the average. If one score is higher than it should be, it will raise the average. Range isnaffected because it is the number in between the max and min (max-min). If the max is higher, then the range increases
Mean: Calculated by adding all the test scores together and then dividing by the total number of tests, so the error in the highest score does not affect the mean.
Median: Calculated by finding the middle value in a set of data, so the error in the highest score does not affect the median, as it will still be the fourth highest test score.
Minimum: The lowest test score remains the same, as it will not be affected by the error in the highest score.
Range: Calculated by subtracting the lowest test score from the highest score, so if the highest score is incorrect, the range will also be incorrect.
Therefore, only the maximum score and the range are altered by George's mistake, and the mean, median, and minimum score remain the same.

The box-and-whisker plots below show the numbers of motor vehicles produced in four different regions for selected years since 1950.
Which region has had the GREATEST amount of variability in annual vehicle production?
A. Japan
B. Europe
C. Canada
D. United States
Answers
Answer: A. Japan
Step-by-step explanation:
Japan would have more variables in the production the vehicles annual leave because it has the longest box out of all other reasons, and when you’re dealing with box equations the longest box has the most variables when the short box has the least variables.
Japan region has had the greatest amount of variability in annual vehicle production.
What is the box-and-whisker plot?
A box and whisker plot displays a "box" with its left edge at Q₁, right edge at Q₃, "center" at Q₂ (the median), and "whiskers" at the maximum and minimum.
More varied data is implied by larger boxes.
When comparing box plots, especially when the medians are comparable, that is something to keep an eye out for.
Whisker lengths and box sizes with wider ranges signify more varied data.
So, from the given choices,
Japan shows the greatest amount of variability.
Therefore, the Japan box plot is the required plot.

A cone has a diameter of 18 units and height of 8 units. What is its volume? 72π cubic units 216π cubic units 648π cubic units 864π cubic units
Answers
Answer:
216π cubic units
Step-by-step explanation:
volume of a cone = πr²h/3
r = radius = 1/2 of diameter = 1/2 of 18 = 9
volume = π*9²*8/3 = 216π
The volume of the cone with a diameter of 18 units and a height of 8 units is
216π cubic units.
Option B is the correct answer.
What is a cone?It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
The volume of a cone is 1/3πr²h.
We have,
Diameter = 18 units
Radius = 9 units
Height = 8 units
The volume of a cone.
= 1/3 π r² h
= 1/3 x π x 9² x 8
= 1/3 x π x 81 x 8
= 27 x π x 8
= 216π cubic units.
Thus,
The volume of the cone is 216π cubic units.

l = 6 cm ; w = 6 cm ; h = 7 cm
\(\sf \boxed{ \text{ surface area = 2h(l+w) + lw}}\)
= 2*7 *(6 + 6 ) + 6*6

Surface area of right triangular prism:
In, right triangular prism, the base rectangle is not included.
Surface area = bh + (S1 + S2)*L
b is the base of the triangle. b= 6 cm
h is the altitude of the triangle. h = 4cm
S1 and S2 are the edges of the triangle.
S1 = 4 cm ; S2 = 7 cm
L is the length of the prism. L = 6 cm
Surface area = 6*4 + (4 + 7)*6

Answer:
no solution
Step-by-step explanation:
when you substitute \(y\) for \(-2x+4\) the equation is false
how I solved this:
1. substitute \(y\) for \(-2x+4\)
\(6x+3(-2x+4)=-12\)
2. distribute the 3
\(6x+-6x+12=-12\)
3. combine like terms
\(12=-12\)
this is incorrect because 12 does not equal -12, so there is no solution

Step-by-step explanation:
Our goal here is to solve -1/3 (4+z)=-5/6 for z.
Begin by multiplying both sides by 6, to eliminate the fractions:
-2(4 + z) = -5
Isolate (4 + z) by dividing both sides by -2: 4 + z = 5/2
Finally, determine z by subtracting 4 from both sides: z = 5/2 - 8/2 = -3/2
z = -3/2
