Answer:
![Area = 90.03cm^2](https://tex.z-dn.net/?f=Area%20%3D%2090.03cm%5E2)
Step-by-step explanation:
Given
![s_1 = 14.9](https://tex.z-dn.net/?f=s_1%20%3D%2014.9)
![s_2 = 14.7](https://tex.z-dn.net/?f=s_2%20%3D%2014.7)
--- angle in between
Required
The area of the plate
Since
is between
and ![s_2](https://tex.z-dn.net/?f=s_2)
The area is:
![Area = \frac{1}{2} * s_1 * s_2 * \sin(\theta)](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20s_1%20%2A%20s_2%20%2A%20%5Csin%28%5Ctheta%29)
![Area = \frac{1}{2} * 14.9 * 14.7 * \sin(124.7)](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%2014.9%20%2A%2014.7%20%2A%20%5Csin%28124.7%29)
![Area = \frac{1}{2} * 14.9 * 14.7 * 0.8221](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%2014.9%20%2A%2014.7%20%2A%200.8221)

Answer:
B
Step-by-step explanation:
The mean is 30, median is 26.875 and mode is 28.19.
<h3>What is Mean?</h3>
The mean for a given set of observations is equal to the sum of all the values of a collection of data divided by the total number of values in the data.
Here, given data:
Class Interval frequency(f) mid value(x) xf
16 - 20 2 18 36
21 - 25 7 23 161
26 - 30 14 28 392
31 - 35 8 33 264
36 - 40 8 38 304
41 - 45 1 43 43
Mean = ∑xf / ∑f
= 1200 / 40
= 30
Median = l + {(n/2)-c}/f X h
= 25.5 + (20-9)X5/40
= 25.5 + 55/40
= 25.5 + 1.375
= 26.875
Mode = l + (f₀-f₁)/ (2f₀-f₁-f₂)Xh
= 25.5 + (14-7)/ (2X 14 - 7 - 8) X 5
= 25.5 + 7/13 X 5
= 25.5 + 35/13
= 25.5 + 2.692
= 28.19
Thus, the mean is 30, median is 26.875 and mode is 28.19.

Okay, this is really easy:) He goes 3/8 miles and 1 and 3/8 miles. to add this together you just go across the top. Discard the 1 for a couple of seconds. so you have 3/8 + 3/8. Now go across the top so you get 6/8. simplify that, (divide by a common number, don't know if you know that or not) so, 2 in this case. you get 3/4. Your answer is 1 and 3/4. Hope this helps and isn't ridiculously confusing:) <span />
