Step-by-step explanation:
1/10 km long, split into 4 equal parts.
so each part is 1/10 / 4 km long.
1/10 / 4 = 1/10 / 4/1 = 1×1 / (4×10) = 1/40
each athlete has to run 1/40 km.
Answer:
a) 1/2 (50%)
b) 1/2 (50%)
c) 3/4 (75%)
d) 3/4 (75%)
Step-by-step explanation:
for a uniform distribution
P(X=x)= x-A/(B-A) , for A≤x≤B
then
P(X=x)= (x+8)/16 , for -8≤x≤8
a) P(X<0)= interval chosen / total interval = (0-(-8))/(8-(-8)) = 1/2 (50%)
b) P(-4<X<4)= interval chosen / total interval =(4-(-4))/(8-(-8)) = 1/2 (50%)
c) P(-5<X<7)= interval chosen / total interval =(7-(-5))/(8-(-8)) = 3/4 (75%)
d) for −8 < k and k + 4 < 8 → k < 4 , then -8<k<4 , thus k
P(X=k)= P(-8<X<4) = interval chosen / total interval =(4-(-8))/(8-(-8)) = 3/4 (75%)
Answer:
x tan q
Step-by-step explanation:
Refer the attached figure
An observer on the ground is x meters from the base of the launch pad of a rocket i.e. BC = x
The height of the rocket is AB
The observer sees its tip at an angle of q° from the horizontal.i.e.∠ACB = q°
In ΔABC
We will use trigonometric ratio
So, the height of the rocket is x tan q.
So, Option C is correct.
Hence the tip of the rocket is x tan q far above the ground
