Please see the attached picture to see the similar triangle.
The new triangle has triple the side lengths of the first one. This means all side lengths will be triple.
You will use this ratio to find the new side lengths and then use them to find the perimeter and area.
3:4:5 = 9 cm: 12 cm:15 cm on triangleABC
1. The
perimeter is 9cm + 12 cm + 15 cm or
36 cm.
2. The
area is 1/2 x 12 x 9 or
54 square cm.
3. The length of the
hypotenuse is
15 cm.
A) 0.2076
B) 0.6786
C) 0.3214
Explanation:A)
![P(X=5)=_8C_5(0.75)^5 \times(1-0.75)^{8-5} \\ \\=_8C_5(0.75)^5 \times (0.25)^3=0.2076](https://tex.z-dn.net/?f=P%28X%3D5%29%3D_8C_5%280.75%29%5E5%20%5Ctimes%281-0.75%29%5E%7B8-5%7D%0A%5C%5C%0A%5C%5C%3D_8C_5%280.75%29%5E5%20%5Ctimes%20%280.25%29%5E3%3D0.2076)
B) We find the probability that X=6, 7, or 8:
![P(X=6)=_8C_6(0.75)^6(0.25)^2=0.3115 \\ \\P(X=7)=_8C_7(0.75)^7(0.25)^1=0.267 \\ \\P(X=8)=_8C_8(0.75)^8(0.25)^0=0.1001 \\ \\0.3115+0.267+0.1001=0.6786](https://tex.z-dn.net/?f=P%28X%3D6%29%3D_8C_6%280.75%29%5E6%280.25%29%5E2%3D0.3115%0A%5C%5C%0A%5C%5CP%28X%3D7%29%3D_8C_7%280.75%29%5E7%280.25%29%5E1%3D0.267%0A%5C%5C%0A%5C%5CP%28X%3D8%29%3D_8C_8%280.75%29%5E8%280.25%29%5E0%3D0.1001%0A%5C%5C%0A%5C%5C0.3115%2B0.267%2B0.1001%3D0.6786)
C) P(X≤5) = 1-P(X>5) = 1-0.6786 = 0.3214

Answer:
-3.0mph/s
Step-by-step explanation:
Why?
- If you apply brakes then your bike will experience a retar dation.
- Hence acceleration will be in -
Step-by-step explanation:
x= how many members are in the group
x= 100/x
x= 100/(x-5)
x(x-5)=100
x^2-5x=100
x^2-5x-100=0
and then use the quadratic formula (i can't type it srry)
