Step-by-step explanation:
Given :
Mean :
![$=-0.0375 \left[ \frac{t^4}{4} \right]^4_0 + 0.225 \left[ \frac{t^3}{3} \right]^4_0$](https://tex.z-dn.net/?f=%24%3D-0.0375%20%5Cleft%5B%20%5Cfrac%7Bt%5E4%7D%7B4%7D%20%5Cright%5D%5E4_0%20%2B%200.225%20%5Cleft%5B%20%5Cfrac%7Bt%5E3%7D%7B3%7D%20%5Cright%5D%5E4_0%24)
= 2.4
Therefore, the mean is 2.4

Answer:
S=157
Step-by-step explanation:
an= a1+(n-1)d
a2=80+(2-1)(-3)
a2=80-3
a2=77
Sn=(a1+an)*n/2
S2=(80+a2)*2/2
S2=(80+77)*1
S2=157
BC is 21 meters.
2x + 5 + 3x = 45
5x + 5 = 45
5x = 40
X = 8
2(8) + 5 = BC
21 = BC
