Reflect triangle ABC over the line y = 2.
Translate the image by the directed line segment from (0, 0) to (3, 2).
What are the coordinates of the vertices in the final image?
Answers
The question is an illustration of transformation, and the coordinates of the image of the triangle are (-3,7), (-2,4) and (0,6)
How to transform the triangle?The coordinates of the triangle are given as:
(-6,-1), (-5,2) and (-3,0)
When the triangle is reflected across the line y = 2 is, the new points are
(-6,5), (-5,2) and (-3,4)
Next, we translate the image of the triangle using the translation
(x,y) -> (x + 3, y +2)
So, we have:
(-6,5) => (-6 + 3, 5 + 2) = (-3,7)
(-5,2) => (-5 + 3, 2 + 2) = (-2,4)
(-3,4) => (-3 + 3, 4 + 2) = (0,6)
Hence, the coordinates of the image of the triangle are (-3,7), (-2,4) and (0,6)

Answers
The probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixt
What is probability?Probability is the likelihood or chance that an event will occur. Mathematically;
Probability = Expected/Total
If the spinner is spinned, the total outcome is 1/6
Pr(greater than 4) = 2/6 = 1/3
Pr(shaded section) = 3/6 = 1/2
Pr(number greater than 4 or on a shaded section) = 1/3 + 1/2
Pr(number greater than 4 or on a shaded section) = 5/6
Hence the probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixths

Stephen bought a package of stickers for $0.50. His brother bought 4 times as many packages. How much did his brother spend? (3 points) a $2.00 b $2.25 c $2.50 d $3.00
Answers
a $2.00
Step-by-step explanation:
0.50 x 4 = 2
If he bought 4 times as many, then take the price times 4.
Answer:
$2.00
Step-by-step explanation:
Stephen bought 1 package for $0.50. His brother bought 4 times as many (4 * 1 packages). Which means his brother bought 4 packages.
If each package costs $0.50 then we simply multiply the price with the amount of packages he bought:
4 * $0.50. Lets get rid of the dollar sign, so it doesn't distract us.
I'm not sure if you studied about floating point numbers yet, but I assume you did.
4 * 0.50 =?
We have two numbers after the floating point, but for the sake of simplicity we can get rid of it too and just multiply 4 * 50 and then put the floating point back into the number after the first two digits (because we removed it after two digits 0.50)
Anyway 4 * 50 = 200
We add the floating point and get:
2.00
Therefore his brother spent $2.00 after we add the dollar sign back in
What fraction of the sweaters cost $50 or less?
Answers
Answer:
8/15 is the fraction I think
The answer is that 50% of the sweaters cost $50 or less.
What is a box plot?To determine the fraction of sweaters that cost $50 or less, we need to look at the box plot and identify the range of prices that fall within that category.
Looking at the box plot, we can see that the box extends from $40 to $60, which means that 50% of the sweaters sold were priced between $40 and $60. Additionally, we can see that the left whisker of the box plot extends down to $30, which means that some sweaters were sold for less than $40.
Therefore, to find the fraction of sweaters that cost $50 or less, we need to calculate the portion of the box plot that falls below $50.
From the box plot, we can see that the distance between $40 and $50 is half of the total distance of the box or 25%. And the distance between $30 and $40 is also 25%. Therefore, the total fraction of sweaters that cost $50 or less is 25% + 25% = 50%.
So, the answer is that 50% of the sweaters cost $50 or less.
