Answer:
M=-10
Step-by-step explanation:
Step 1, subtract 1/6m from both sides leaving the equation: 1/2m+2=-3
Step 2, subtract 2 from both sides leaving the equation: 1/2m=-5
Step 3, Multiply both sides by 2 leaving the equation: m=-10
Answer:
Step-by-step explanation:
1. The probability that your mail is delivered before 2 pm is 0.9, so the probability that the mail is delivered at 2 pm or after 2 pm (so not before 2 pm) is 1-0.9=0.1.
Remark: 0.9=9/10=90/100=90%, and 0.1 is 10%
2. Probability of the mail being delivered before 2 pm for 2 consecutive days is
3. take a look at the picture attached, the tree diagram is another method we could use.
A way that I use to determine if something is a function or not is to ask whether or now it passes the “vertical line test”. In other words, does an x have two y’s? if we graphed these points, and proceeded to draw a vertical line through it, if it touches the function twice, then it is not a function. So I believe your answers would be A and C (In A, when x is 2, there are two y’s. Same goes with C, when x is 1, 4, 9 etc).
I hope this answer helps! :)
Answer:
The correct answer is option D. 69°
Step-by-step explanation:
Points to remember
1). The sum of angles in a linear pair is 180°
2). In a triangle sum of two angles are equal to the exterior angle of third angle
From the figure we can see a triangle in which two exterior angles area given.
<u>To find the value of n</u>
from figure we get,
n = (interior angle of 131° + interior angle of 160°)
interior angle of 131° = 180 - 131 = 49°
interior angle of 160° = 180 - 160 = 20°
n = 49° + 20° = 69°
Therefore the correct answer is option D. 69°
