Answer:
m∠K = 36°
m∠L = 54°
m∠M = 90°
Step-by-step explanation:
A triangle's angles add up to 180 degrees. We will add together all the angles and set them equal to 180. Then, we will solve for x. Lastly, we will solve for the angle measurements.
-> The little "box" in angle M means that it is equal to 90°
90° + (2x + 42)° + (4x + 12)° = 180°
90° + 42° + 12° + 2x° + 4x°= 180°
144° + 6x°= 180°
6x° = 36°
x = 6°

Step-by-step explanation:
take two points, (1,13) (2,19)
subtract using slope formula
19-13 2-1= 6/1 -> 6-> 3
find your y intercept (b) by using the first term in the 7 row (7)
Answer:
y = 3x +
Step-by-step explanation:
The equation of the line is given by:
----------------------------
The equation of a line, in slope-intercept formula, has the following format:
In which
m is the slope, that is, how much y changes when x changes by 1.
b is the y-intercept, that is, the value of y when x = 0.
----------------------------
Given two points (x,y), the slope is the change in y divided by the change in x.
We have points (-1, -1) and (3,11). Thus:
Then
----------------------------
Point (-1,-1) means that when , and we use this to find b.

O 17

median = the middle number {always remember this}.
To find the median of a set of numbers we arrange that set of numbers either in ascending order (smallest to biggest value) or in descending order ( biggest to smallest value).
so we are given :
20, 19, 13 , 23, 16, 15 , 17, 17, 15 , 15, 22, 19, .
we rearrange in ascending order (I chose ascending order).
Soo...
13, 15, 15, 15, 16, 17, 17 , 19, 19, 20, 22, 23.
so we cancel out (we cancel out left number, right number)
I mean
cancel out 13, cancel out 23
cancel out 15, cancel out 22
cancel out 15, cancel out 20 and so on.....
after that we will be left with 2 numbers which are 17 and 17.
NOTE: ( if we get 2 numbers instead of 1, then we add those 2 numbers and divide by 2)
so...
17 + 17 = 34
34/2 = 17.
the median of the set of numbers is equal to 17.
Hope this helps.

From the table we can conclude that after 2 minutes the height of the water is increased by 4.
Example: In minute 2 it was 8 inches, in minute 4 it was 12 inches. (12-8=4)
This means that if the height of the water is increased by 4 inches for 2 minutes, then for 1 minute is increased 4/2=2 inches.
The following statement best describes how the slope relates to the height of the water in the pool:
The height of the water increases 2 inches per minute.

How can you verify using distance that the center of rotation is the origin?
If the distance between the origin and the points on the path of rotation is equal, the origin will be the center of rotation for any system.
What is center of rotation?Center of rotation is the point about which the rotation takes place. this point is equidistant from all points in the path of rotation.
We are asked to verify that the center of rotation is the origin.
In this case, the center of rotation will be equidistant from all the points in the locus of rotation. So, the distance between the origin and any point on the path of rotation will be equal.
Thus, if the distance between the origin and the points on the path of rotation is equal, origin will be the center of rotation for any system.

Which equation represents the transformed function below? on a coordinate plane, a parent function starts at (0, negative 1) and then curves up into quadrant 1 and approaches y = 1. a transformed function starts at (0, 4) and then curves up into quadrant 1 and approaches y = 6. _____ = parent function; y = log x - - - - - = transformed function y = log x 5 y = log x minus 5 y = log (x 5) y = log (x minus 5)
The parent function which starts at (0, -1) and then curves up into quadrant 1 is logx and the transformed function which starts at (0, 4) and then curves up into quadrant 1 is logx+5.
What is transformation of a function?Transformation of a function is shifting the function from its original place in the graph.
Types of transformation-
Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)-c shifts the graph c units down and by replacing parent function with f(x)+c shifts the graph c units up.On a coordinate plane, a parent function starts at (0, -1) and then curves up into quadrant 1 and approaches y = 1. Thus, the function of this curve is,
y=logx
A transformed function starts at (0, 4) and then curves up into quadrant 1 and approaches y = 6.
y=logx +5

At LaGuardia Airport for a certain nightly flight, the probability that it will rain is 0.18 and the probability that the flight will be delayed is 0.14. The probability that it will not rain and the flight will leave on time is 0.74. What is the probability that the flight would leave on time when it is not raining? Round your answer to the nearest thousandth.
The probability that the flight would leave on time when it is not raining is: 0.522
What is probability?Probability is the likelihood of an event happening or not.
Analysis:
pr( it will rain) = 0.18
Pr( it will not rain) = 1 - 0.18 = 0.82
Pr ( flight will be delayed) = 0.14
Pr( it will not be delayed) = 1 - 0.14 = 0.86
Pr( it will not rain and flight would leave early) = 0.74
Pr( flight leave early when not raining) = pr( it willnot rain) x Pr( it will not be delayed) x Pr( it will not rain and flight leave on time) 0.82 x 0.86 x 0.74 = 0.522
In conclusion, the probability that flight would leave on time when it is not raining is 0.522
