X=3 because the equation is 9x=5x + 9 + x.
Answer:
What? I don't see anything.
Step-by-step explanation:
The pigeon can fly 7 kilometers in around 8-9 minutes
Let x be the lengths of the steel rods and X ~ N (108.7, 0.6)
To get the probability of less than 109.1 cm, the solution is computed by:
z (109.1) = (X-mean)/standard dev
= 109.1 – 108/ 0.6
= 1.1/0.6
=1.83333, look this up in the z table.
P(x < 109.1) = P(z < 1.8333) = 0.97 or 97%
Answer:
Option A. 
Step-by-step explanation:
we know that
The measure of the median is the semi-sum of the bases
so
