What is the image point of (-2,6) after a translation left 2 units and up 4 units?
Answer:
[tex](-4,10)[/tex]
Step-by-step explanation:
When you translate (x,y), left 2 units and up 4 units, it becomes (x-2,y+4)
We are given the point (-2,6).
We want to find the image of this point after a translation left 2 units and up 4 units.
[tex](-2,6)\to(-2-2,6+4)[/tex]
We simplify to get:
[tex](-2,6)\to(-4,10)
[/tex]
Final answer:
The image point of (-2,6) after a translation left 2 units and up 4 units is (-4,10).
Explanation:
To determine the image point of (-2,6) after a translation left 2 units and up 4 units, we simply need to adjust the x-coordinate and the y-coordinate by the amounts specified by the translation. Moving left 2 units means we subtract 2 from the x-coordinate, and moving up 4 units means we add 4 to the y-coordinate.
Starting with the x-coordinate of -2, we subtract 2:
-2 - 2 = -4.
So, the new x-coordinate is -4.
Starting with the y-coordinate of 6, we add 4:
6 + 4 = 10.
So, the new y-coordinate is 10.
Therefore, the image point after the translation is (-4,10).

Question 1 a
A marketing executive is investigating whether this year's advertising campaign has resulted in greater mean sales compared with last year's mean sales. The executive collects a random sample of 100
customer orders from a large population of orders and calculates the sample mean and sample standard deviation
Which of the following is the appropriate test for the executive's investigation?
Answer:
B) A one-sample t-test for population mean would be used.
Step-by-step explanation:
The complete question is shown in the image below.
The marketing executive is interested in comparing the mean number of sales of this year to that of previous year.
The marketing executive already has the value of mean from previous year and uses a sample to calculate the mean and standard deviation of sales for the current year.
Since, data is being collected for one sample only this limits us to chose between one sample test for mean. So now the possible options are one sample t-test for population mean and one sample t-test for population mean.
If we read the statement we can see that we have the value of sample mean and sample standard deviation. Value of population standard deviation is unknown. In cases where value of population standard deviation is not known and sample standard deviation is given, t-test is used.
Therefore, we can conclude that A one-sample t-test for population mean would be used.
T test is the test is a statistical test that is used to compare the means of two groups. The option B is correct option because a one sample t test for a population mean is the appropriate test for the executive's investigation for the given problem.
Given-
The options for the given question are-
A) A one sample z test for a population mean.B) A one sample t test for a population mean.C) A one sample z test for a population proportion.D) A two sample t test for a difference between means.E) A matched pairs t test for a mean difference.T testT test is the test is a statistical test that is used to compare the means of two groups.
In the given problem the marketing executive wants to compare the annual sales mean number for the this year to the past year.
The mean value of the past year is known to the marketing executive.
The mean value of this year has to be calculated by the marketing executive.
For this the executive collects a random sample of 100 customer orders from a large population of orders and calculates the sample mean and sample standard deviation.
As t test is used to determine a significant difference between the means of the two groups which may be related in certain features. Thus this test is best suitable for the given problem.
Hence the option B is correct option because a one sample t test for a population mean is the appropriate test for the executive's investigation for the given problem.

What is the wright answer
Answer:
Yes, these two fractions are equivalent. Additional equivalent fractions are given below.
Step-by-step explanation:
To determine if two fractions are equivalent, we should simplify each fraction into its simplest form.
Brett's fraction is 4/8. To simplify this fraction, we should divide both the numerator the denominator by the GCF, or greatest common factor. The GCF is 4, so we should divide both of these numbers by this factor to simplify. This is shown below:
4/8 = 4/4 / 8/4 = 1/2
Aisha's fraction is 1/2. Since the GCF of 1 and 2 is 1, we know that this fraction is already in its simplest form.
When we compare the simplified versions of the two fractions, we see that they are both 1/2; therefore, they are the same.
To determine additional equivalent fractions, we should multiply both the numerator and the denominator by the same factor. For example, 4/8 is generated by multiplying both the numerator and denominator by a factor of 4. By this same logic, 2/4, 3/6, and 5/10 are all also equivalent fractions (multiplied by factors of 2, 3, and 5, respectively).

Four students set up a lemonade stand.At the end of the day,their profit is $17.52. How much money do they have when the profit is split equally?
Answer:
$4.38
Step-by-step explanation:
Lets recap the information we are told in the problem:
There are 4 students in total
Their total profit is $17.52
The total profit needs to be split equally between them
Now we can focus on solving. To do so we can set up an equation like this:
(Total profit) ÷ (Number of students) = (Amount each student gets)
Lets insert our numbers into this equation:
$17.52 ÷ 4 = $4.38
So each student gets $4.38 each when the profit is split equally.
Out of the entire profit of $17.52, each one of the students will be able to take home a profit of $4.38.
These four students were able to sell enough lemonade that they made $17.52.
They will need to divide the profit amongst themselves and when they do so, each one of them will get:
= Profit made / Number of students
= 17.52 / 4
= $4.38
In conclusion, each one of the students will get $4.38.

Triangle STV has side lengths of 7, 11, and 14 units. Determine whether this triangle is a right triangle.
The triangle STV is not a right angled triangle.
Explanation:
Given that STV is a triangle with side lengths of 7, 11 and 14 units
We need to determine that STV is a right angled triangle.
Using Pythagorean theorem, we have,
[tex]c^2=a^2+b^2[/tex]
where [tex]c=14, a=7[/tex] and [tex]b=11[/tex]
Substituting the values in the above formula, we have,
[tex]14^2=7^2+11^2[/tex]
Squaring the terms, we get,
[tex]196=49+121[/tex]
[tex]196=170[/tex]
Since, both sides of the equation are not equal, then the triangle STV is not a right angled triangle.
Final answer:
To determine if triangle STV is a right triangle, apply the Pythagorean theorem. The theorem shows that STV is not a right triangle because the squares of the two shorter sides do not add up to the square of the longest side.
Explanation:
To determine whether triangle STV with side lengths of 7, 11, and 14 units is a right triangle, we can use the Pythagorean theorem. Pythagorean theorem states that for a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In mathematical terms, if c represents the length of the hypotenuse and a and b represent the lengths of the other two sides, then the triangle is right if and only if c² = a² + b².
For triangle STV, let's assign the longest side, which is 14 units, as the hypotenuse c, and the other two sides as a and b. So:
a = 7 units
b = 11 units
c = 14 units
Now, we check:
c² = 14² = 196
a² + b² = 7² + 11² = 49 + 121 = 170
Since 196 does not equal 170, we conclude that triangle STV is not a right triangle.

Step-by-step explanation:
the difference is 4 if you do 12-8=4
the product sum is 96 which is 12*8=96
Answer:
12 and 8
Step-by-step explanation:
Let the numbers be x and y
x - y = 4 ................(1)
xy = 96 ..................(2)
From equation 1
x = 4+y ..............(3)
Put x = 4+ y into equation 2
y(4+y) = 96
y² +4y = 96
y² + 4y - 96 = 0
Solve quadratically using factorisation method
y² + 12y - 8y - 96 =0
y(y+12) - 8 ( y + 12) = 0
(y +12)(y -8) = 0
y = -12 or 8
When y = -12
x = 4+y = 4-12 = -8
When y= 8
x = 4+y = 4+8 =12
Numbers are 12 and 8 or -8 and -12

the year 2000, a company made $4.9 million in profit. For each consecutive year after that, their profit increased by 13%. How much would the company's profit be in the year 2003, to the nearest tenth of a million dollars?
Answer:
14.7 is the best answer i can come up with it might be wrong it might not be to be helpful there you go
Step-by-step explanation:
To find the company's profit in the year 2003, we need to apply a 13% increase for each consecutive year. Starting from an initial profit of $4.9 million in 2000, we can calculate the profit for each year using the given formula.
Explanation:To find the company's profit in the year 2003, we need to apply the given increase of 13% for each consecutive year. Starting from the initial profit of $4.9 million in 2000, we can calculate the profit for each year using the formula:
New Profit = Previous Profit + (Previous Profit * 0.13)
Using this formula, we can determine the profit for the year 2003 as follows:
Year 2000 Profit: $4.9 million
Year 2001 Profit: $4.9 million + ($4.9 million * 0.13) = $5.537 million
Year 2002 Profit: $5.537 million + ($5.537 million * 0.13) = $6.267 million
Year 2003 Profit: $6.267 million + ($6.267 million * 0.13) = $7.082 million
Therefore, the company's profit in the year 2003 would be approximately $7.082 million to the nearest tenth of a million dollars.
If you earn $2850 per month and you expect your earnings to increase by 6.6% per year, how much do you think you will be making in 2 years?
Answer:
To calculate how much you will be making in 2 years, given that you earn $2850 per month and your earnings are expected to increase by 6.6% per year, we can follow these steps:
1. Calculate the annual increase: To find the annual increase, we multiply the current earnings by the percentage increase. In this case, the annual increase would be 2850 * 0.066 = $188.10.
2. Calculate the total increase over 2 years: Since the earnings are expected to increase by the same amount each year, we can multiply the annual increase by 2 to get the total increase over 2 years. In this case, the total increase would be 188.10 * 2 = $376.20.
3. Calculate the future earnings: To find the future earnings after 2 years, we add the total increase to the current earnings. In this case, the future earnings would be 2850 + 376.20 = $3226.20.
Therefore, based on the given information, you can expect to be making approximately $3226.20 in 2 years.
If you earn $2850 per month with an annual increase of 6.6%, in two years you will be making approximately $3239.40 per month.
If you are currently earning $2850 per month and expect your earnings to increase by 6.6% each year, then to calculate your earnings in 2 years, we need to take into account the compound interest formula which can be applied to salary growth as well. The formula to calculate the future value after a certain number of years is:
Future Value = Present Value x (1 + Rate of Increase)Number of Years
In this case, your Present Value is $2850, the Rate of Increase is 6.6% (expressed as a decimal, which is 0.066), and the Number of Years is 2.
Calculate the earnings for the first year: $2850 x (1 + 0.066) = $3038.10.
Then calculate the earnings for the second year: $3038.10 x (1 + 0.066) = approximately $3239.40.
Therefore, in two years, you would be making approximately $3239.40 per month.
A rectangular one-story house covers an area of 3,700 square feet. The ceilings are 8 feet high. The owners add a second floor to the house. The second floor is 50 feet long and 30 feet wide with ceilings that are 9 feet high. What is the total volume of the interior of the house?
The total volume of the interior of the house after adding a second floor is 43,100 cubic feet, calculated by summing the volume of the original one-story (29,600 cubic feet) and the second floor (13,500 cubic feet).
To calculate the total volume of the interior of the house after the addition of a second floor, we need to find the volume of both floors and add them together. The original one-story house covers an area of 3,700 square feet with ceilings 8 feet high. To find the volume, we multiply the area by the height of the ceilings:
Volume of first floor = Length * Width * Height = 3,700 ft^2 * 8 ft = 29,600 ft^3
The second floor is a bit smaller than the first floor, with dimensions of 50 feet by 30 feet and ceilings that are 9 feet high. So, the volume of the second floor is:
Volume of second floor = Length *Width*Height = 50 ft*30 ft *9 ft = 13,500 ft^3
Adding the two volumes together gives us the total volume of the house:
Total Volume = Volume of first floor + Volume of second floor = 29,600 ft^3 + 13,500 ft^3 = 43,100 ft^3

A jar contains only pennies, nickels, dimes, and quarters. There are 25 pennies, 21 dimes, and 29 quarters. The rest of the coins are nickels. There are 92 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
(This solves to n = 17 meaning there are 17 nickels)
=====================================================
Explanation:
"There are 25 pennies, 21 dimes, and 29 quarters", so there are 25+21+29 = 75 coins so far. This is the amount of coins that aren't nickels. The rest are nickels, which is some amount n. This adds to the 75 to get 75+n. Set this equal to 92 because there are 92 coins in all. That's how we end up with 75+n = 92.
-----
Extra info
The equation 75+n = 92 is the same as n+75 = 92. Subtract 75 from both sides to isolate n. You should get n = 17 after doing so.
To find the number of coins that are not nickels, subtract the number of nickels from the total number of coins. Alternatively, solve for 'n' by subtracting the known quantities of pennies, dimes, and quarters from the total number of coins.
Explanation:To find the number of coins that are not nickels, we need to subtract the number of nickels from the total number of coins. Given that there are 92 coins in total and the number of nickels is represented by 'n', the equation to find the number of coins that are not nickels is 92 - n.
Alternatively, we can solve for 'n' by subtracting the known quantities of pennies, dimes, and quarters from the total number of coins. We know there are 25 pennies, 21 dimes, and 29 quarters. So, we have n = total number of coins - number of pennies - number of dimes - number of quarters = 92 - 25 - 21 - 29. Simplifying this equation gives us the value of 'n'.
