The sum of all angles in a triangle sum up to 180.
∠1 = x+37
∠2=x+67
∠3=90° (right triangle)
∠1+∠2+∠3 = 180°
(x+37)+(x+67)+90=180
2x+104+90=180
2x+194=180
2x=-14
x=-7
An angle can't be negative, but when plugged in it works!!
∠1 = -7+37=30
∠2=-7+67=60
30+60+90=180
Hope it helps!
Answer: Company A mean = 14.65 million Company B mean = 14.32 million.
Step-by-step explanation:
The mean, or average, is calculated by adding up the scores and dividing the total by the number of scores.
Company A mean = 12.8 + 15.0 + 31.0 + 13.0 + 14.0 + 12.9 + 12.7 + 11.9 + 11.7 + 11.5 = 146.5/ 10 = 14.65 million
Company B mean = 13.8 + 14.0 + 14.5 + 14.3 + 14.6 + 14.5 + 14.2 + 14.7 + 14.4 + 14.2 = 143.2/ 10 = 14.32 million
The median is the middle score of a distribution. To calculate the median
Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
Currently i'm providing you the mean solution im working on the median I haven't learned it.
Answer:
(x, y) = (8, -3)
Step-by-step explanation:
You can substitute for x in the first equation:
3(-3y -1) +3y = 15
-6y = 18 . . . . . add 3 and simplify
y = -3 . . . . . . . divide by -6
x = -3(-3) -1 = 8 . . . . find x using the second equation
The solution to this system of equations is (x, y) = (8, -3).
Answer:
B
Step-by-step explanation:
If you're looking for direct correlation, you're looking for a proportion for the second box. So you set the ratio of 2.5:5.5 up as a fraction. 2.5/5.5 and set it equal to the second box 3/x.
2.5 = 3
5.5 x
cross multiply
16.5=2.5x
and divide
16.5/2.5 and you get your answer
7x300=7x 3 hundres because in 300 hundreds there is 3 hundreds.I know that didnt make sense.so basically just look at the front number number its 3 so 3 hundreds but if your working with thousands and the front number is 5 its 5 thousands.I hope this was helpful.
