Step-by-step explanation:
tan = perpendicular / base
acc. to diagram ,
angle C = 90°
such that
AB is hypotenuse
acc to theta ,
AC is perpendicular and BC is base
therefore
tan theta = AC / BC
tan theta = 8/15
Answer:
Step-by-step explanation:
<u>Slope intercept form:</u>
- y = mx + b, where m - slope, b - y-intercept
<u>Take two points from the graph:</u>
<u>Find the slope:</u>
- m = (3 - 1)/(3 - 1) = 2/1 = 2
<u>Find the y-intercept using point (2, 1) and the equation above:</u>
- 1 = 2*2 + b
- b = 1 - 4
- b = -3
<u>The line is:</u>
Answer:
81 / 256
Step-by-step explanation:
just multiply 3/4 4 times
(Just because I'm a high schooler doesn't mean that I don't know this I take AP and IB classes)
Answer:
6
Step-by-step explanation:
-15+6 means it goes minus basically its 15-6(-15+6)=-9
The standard deviation is the square root of the variance
so if the variance is 196, then the standard deviation is the sqrt of 196, which is 14
