Answer:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

Step-by-step explanation:

The table below shows the number of marbles of different colors in a bag:
noname [10]
There are a total of 5+8+2=15 marbles.  There's a 5/15 chance of drawing a red marble in the first trial.  Then, there are 4 red marbles and 14 total marbles left, so afterwards, there's a probability of 4/14 that the second marble is red.  The probability overall is found by multiplying these together, so the first answer is the best.

There are 2+6+7=15 cakes.  There's a 6/15 chance that the first cake selected will be a pineapple cake, and then a 2/14 chance that the second cake selected will be a strawberry cake, by the same logic as above.  This is equal to 12/210.  The first answer is the best option.

Box and whisker plots please help!
kotykmax [81]
The correct answer is D. 100%
Each tick counts as 8 so the beginning of the plot would be at 28 which is only 2 from 30 and everything else is on the plot is greater than 30 so the answer would have to be D since 75% would be too little coverage of the plot

.........simplify 3^2*3^5
Liula [17]
Using order of operations, we can see we should first solve for the exponents, and then multiply the exponent values by each other.


3²×3^{5}
9×243
2187

Another way to solve this is to add the exponents together and simply do 3^{7}. We can only do that in this case, however, because the values are being multiplied by each other.

Either way we solve, we will get 2187 as our final answer.
