Answer:

Step-by-step explanation:

The median is the middle value of the data in ascending order. If there is no exact middle then it is the average of the two values either side of the middle.

Arrange in ascending order

12, 15, 15, 18, 20, 29, 33, 42

The middle is between 18 and 20

median = $\frac{18+20}{2}$ = $\frac{38}{2}$ = 19

Answer:

Step-by-step explanation:

Hey diddle diddle the medians in the middle you add then divide for the mean. the mode is the one that appears the most and the range is the difference in between.

Median: you have to organize the numbers from least to greatest then eliminate one by one.

12, 15, 15, 18, 20, 29, 33, 42

eliminate 12, and 42

15, 15, 18, 20, 29, 33

eliminate 15, and 33 ... so on

once you get to the median you end up with two numbers.

18, 20

because you can only have one median you find the number between, which in this case would be 19

What are the coordinate of ABC after a dilation with center 0,0 and a scale factor of 3 please help

mojhsa [17]

Answer:

Note that both the x and y coordinates are multiplied by the SAME value, k. Given ΔDEF with center of dilation the origin (0,0) and scale factor of 2, plot ΔD'E'F'. As shown in the formula above, multiply each x and y coordinate value by the scale factor of 2 to find the new coordinates

We know that angle MKJ is comprised of angle MKL and angle LKJ. That means if we add MKL and LKJ, we should get 80 degrees, which is the measure of angle MKJ.

$MKL + LKJ= MKJ \implies \\ 2x+10+3x-5=80 \implies \\ 5x+5=80 \implies\\ 5x=75 \implies \\ x=15$

So, we know that our x is 15. That is not enough to tell whether KL is an angle bisector, because we have to evaluate both MKL and LKJ with x=15, so:

$MKL=2(15)+10 = 40\\ LKJ=3*15-5=40$

So we see that these two angles are actually bisectors, and the third question best describes this phenomenon.

Find what equals to x and what equals to y

Nuetrik [128]

Answer:

x=15√2 y=90 degrees.

Step-by-step explanation:

Thanks to the Pythagorean Theorem we know that with any right triangle, A^2+B^2=C^2. In this case we can use 15^2+15^2=sqrt of 450. The square root of 450 is 15 times the square root of 2. Thus x=15√2. Now we need to find y. All angles in a triangle add up to 180 so if we have 45+45+y=180 then y=90.

Amy bought a bag of chips for 0.75, a sandwhich for 5.50, a bottle of water for 1.60. How much does amy have left from 10.

ch4aika [34]

Answer:

Amy would have 2.15 left

Step-by-step explanation:

To find out how much she has left, subtract the cost of the items from 10.

10 - 0.75 - 5.50 - 1.60 = 2.15
