Step-by-step explanation:
Given : Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a variance of and a mean life span of
hours.
Here ,
Let x represents the life span of a monitor.
Then , the probability that the life span of the monitor will be more than 14,650 hours will be :-
Hence, the probability that the life span of the monitor will be more than 14,650 hours = 0.1357
Answer:
The Ration of length 2.0 meters to the length 1.2 meters = 5 : 3
Step-by-step explanation:
The given two length are 2.0 m and 1.2 m
Length L1 = 2.0 m And
Length L2 = 1.2 m
SO, The ratio of L1 : L2 =
Or, The ratio of L1 : L2 =
∴ The ratio of L1 : L2 =
Hence The ratio of L1 : L2 is 5 : 3 Answer
Answer:
<h3>B. 4units</h3>Step-by-step explanation:
Find the diagram attached. The diagram is a similar triangle.
From the diagram, XZ/XY = CA/AB
Given XZ = 2x-2+2x-2 = 4x-4
XY =5x-7
CA = 2x-2
AB= x+1
On substituting this parameters into the formula to get x first
4x-4/5x-7 = 2x-2/x+1
cross multiply
(4x-4)(x+1) = 5x-7(2x-2)
open the parenthesis
4x²+4x-4x-4 = 10x²-10x-14x+14
4x²-4 = 10x²-24x+14
10x²-4x²-24x+14+4 = 0
6x²-24x+18 = 0
x²-4x+3 = 0
x²-3x-x+3 = 0
x(x-3)-1(x-3) =0
(x-3)(x-1) = 0
x = 3 and 1
Next is to get length AX.
Given AX = 2x-2
Substitute x = 3 into the expression
AX = 2(3)-2
AX = 6-2
AX = 4 units
Hence the measure of length AX is 4 units
