Set it up as a fraction:
8kg = 10kg
24N ?N
cross multiply
8x=240
x=30N
Answer:
0.9995
Step-by-step explanation:
10% = 0.10
1 - 0.10 = 0.9
n = number of light bulbs = 7
we calculate this using binomial distribution.
p(x) = nCx × p^x(1-p)^n-x
our question says at most 4 is defective
= (7C0 × 0.1⁰ × 0.9⁷) + (7C1 × 0.1¹ × 0.9⁶) + (7C2 × 0.1² × 0.9⁵) + (7C3 × 0.1³ × 0.9⁴) + (7C4 × 0.1⁴ × 0.9³)
= 0.478 + 0.372 + 0.1239 + 0.023 + 0.0026
= 0.9995
we have 0.9995 probability that at most 4 light bulbs are defective.

Step-by-step explanation:
Answer:
The rate of the slower cyclist is
and that of the faster cyclist is
Step-by-step explanation:
We let x be the rate of the slower cyclist
From the question, the distance between the two towns is 253 and the time taken for the two cyclist to meet is 5 hours
so we can write the equation
We simplify to get the value for x
Hence the rate of the slower cyclist is
and that of the rate faster cyclist is
The slope should be 3/5 because the rise over run using the points (0,3) and (5,6) result in 3/5.
