t value lies between (2,3) so, answer is option d
Answer:
4.61 m
Step-by-step explanation:
The angle of depression of the bottom of the shorter building from the top of the taller building = 48° equals the angle of elevation of the top of the taller building from the bottom of the shorter building
Using trig ratios
tan48° = H/d where H = height of taller building and d = their distance apart = 12 m
H = dtan48° = 12tan48° = 13.33 m
Also, the angle of elevation of the top of the shorter building from the bottom of the taller building is 36°
Using trig ratios
tan36° = h/d where h = height of shorter building
h =dtan36° = 12tan36° = 8.72 m
Now, the difference in height of the buildings is thus H - h = 13.33 m - 8.72 m = 4.61 m
Answer:
Assume that the formula is true for the (k+1)term

I learned this in class a couple weeks ago in intermediate algebra
-2/5=-.4
-7=-7
These two are repeating decimals.
3/9=.3333334
11/12=.9166667
Answer:
C.
Mean= 4.9
Mean Absolute Deviation (MAD): 4.099173553719
Step-by-step explanation:
An outlier is a value that is very different from the other data in your data set. This can skew your results. As you can see, having outliers often has a significant effect on your mean and standard deviation. Because of this, we must take steps to remove outliers from our data sets.
outlier: 21
