The resulting coordinate points after translation is (4, -4), (0, -2) and -6,-2)
Translating coordinates ofa triangleThe triangle is a shape that has three sides and angles. Given the coordinate points of the triangle given as:
A(-2, 3)
B (-2, 5)
C (-4, 5)
If the coordinate points is translated by the vector (2, -7), hence the resulting coordinate points will be:
A' = (2+2, 3-7) = (4, -4)
B' = (-2+2, 5-7) = (0, -2)
C' = (-4-2, 5-7) = (-6,-2)
Hence the resulting coordinate points after translation is (4, -4), (0, -2) and -6,-2)

Angelo drove home from college traveling an average speed of 71.7 mph and drove back to the college the following week at an average speed of 64.1 mph. if the total round trip took 5 hours, how much time did it take angelo to drive from home back to college? express the time in hours and minutes. round to the nearest minute.
Answers
When Angelo drove home from college with an average speed of 71.7 mph and back to college with an average speed of 64.1 mph, she took 5 hours for full trip then the time taken to travel from home to college is 2.63 hours
Given,
The average speed from college to home = 71.7 mph
The average speed from home to college = 64.1 mph
We know,
Speed = Distance / Time
Consider the total distance as x
Time taken = Distance / Speed
Then the time taken to travel from college to home = [tex]\frac{x}{71.7}[/tex] hours
time taken to travel from home to college = [tex]\frac{x}{64.1}[/tex] hours
Total time taken = 5 hours
Then the equation will become
[tex]\frac{x}{71.7}+\frac{x}{64.1}=5[/tex]
Cross multiply the terms
[tex]\frac{64.1x+71.7x}{(71.7)(64.1)}=5\\ \frac{135.8x}{4595.97}=5[/tex]
135.8x= 5×4595.97
135.8x=22979.85
x=169.21
Time taken to travel from home to college =[tex]\frac{169.21}{64.1}[/tex]
=2.63 hours
Hence, When Angelo drove home from college with an average speed of 71.7 mph and back to college with an average speed of 64.1 mph, she took 5 hours for full trip, then the time taken to travel from home to college is 2.63 hours

What is the solation to the equation?
√x+7= -2
Answers
√x+7 The solution to the equation is x=-3.
Square root: If we take the square root of a number and then take the square of the outcome, we get the original number back again.
e.g. 4 = 2 and 22 = 4.
We can say that the square root and the square cancel each other out. They are the inverse of each other.
If we have a number written with the index 2 ( squared) then taking the square root simply means that we leave out the 2 ( this only applies to positive numbers ).
We can therefore take any squared numbers that are under the square root sign out from under the root sign by leaving out the power 2.
The solution to the equation√x+7= -2.
√x+7= -2
First we take Squaring on both sides
(√x+7)2= (-2)2
x+7 = 4
x=-3.

which of the following is an advantage of a cumulative frequency polygon over a histogram or frequency polygon?
Answers
The significant benefit of a cumulative frequency polygon above a histogram and frequency polygon is that it can demonstrate the total number of observations that are less than the upper limit of a specific class.
What is cumulative frequency polygon?A line segment-joined plot of a cumulative frequency against by the upper class boundary. An ogive would be any continuous cumulative frequency curve, along with a cumulative frequency polygon.
Some main points related to cumulative frequency polygon are-
The cumulative frequency graph can graphically represent data organized in the pattern of a cumulative frequency distribution. The method for drawing cumulative frequency polygons as well as cumulative frequency curves and perhaps ogives is similar. The only distinction in that a cumulative frequency polygon is formed by connecting points with line segments, whereas the cumulative frequency polygon is formed by connecting points with a free hand smooth curve.The cumulative frequency polygon is primarily a line graph drawn on graph paper by projecting the actual lower and upper limits of a class intervals on the x-axis and their respective cumulative frequencies on the y-axis.To know more about the cumulative frequency polygon, here

To make a sweater out of fabric, ruth needs 1 1/2 yards of fabric. if ruth bought 8 3/4 yards of fabric, how many sweaters can she make?
Answers
Given she bought 8 3/4 yards and 1 1/2 is needed, we can set up an equation:
1.5x ≈ 8.75
8.75 / 1.5 gives us 5.8333 repeating. Because it is irrational to make 5.8 sweaters, we should round down to the necessary approximation. Rounded down, 5.8 is 5. Therefore, Ruth can make a maximum of 5 sweaters.

Of the students that stated they would be going to Camp Redwood, 20% did not go to camp. Of the students that stated they would be going to Camp Kern, 15% did not go to camp. How many more students went to Camp Kern than Camp Redwood?
Answers
If the students that stated they would be going to Camp Redwood, 20 percentage did not go to camp and the students that stated they would be going to Camp Kern, 15 percentage did not go to camp, then 51 more students went to camp kern than camp redwood
The total number of students in Camp redwood =170
Number of students who didn't attend the camp redwood = 170×(20/100)
=34 students
Number of students who went to camp redwood =170-34
=136 students
Total number of students in Kern camp = 220
Number of students who didn't attend the camp Kern=220×(15/100)
=33 students
Number of students who went to camp kern =220-33
=187 students
How many more students went camp Kern than Camp Redwood= 187-136

Which of these fractions is equal to 1? A 31/31 B 17/18 C 1/5 D 7/4
Answers
Answer:
A
Step-by-step explanation:
31 divided by 31 is 1 (Since fractions are basically division)
B is incorrect because 17 is one number less than 18.
C is incorrect because 1 is four numbers less than what would equal a whole.
D is incorrect because the numerator is greater than the denominator, which would mean that the fraction 7/4 is greater than a whole.
A, however, is correct; 31 = 31, meaning they are the same number. If the numerator and denominator are equal, we know that we have a whole. Therefore, A is correct.

What is variability?The term "variability" (also known as "spread" or "dispersion") describes how dispersed a set of data is. You may use statistics to compare your data to other sets of data by using the term "variability" to indicate how much the data sets differ from one another.
In a data collection, there are four major approaches to describe variability:
Range: The difference between your smallest and largest piece in the set called the range.Interquartile range: The interquartile range is virtually identical to the range, with the exception that you only give the value for the "middle fifty" as opposed to the range for the whole data set.Variance: A data set's variance offers you a general indication of how evenly distributed your data is.Standard deviation: You may determine how closely your data is grouped around the mean using the standard deviation (the average).To learn more about variability , visit:
