Answer:
a) 0.970225
b) 0.999775
c) 0.000225
Step-by-step explanation:
probability of one system not working =1-0.985=0.015
a)
probability of one system is 0.985 then
Probability of both system = 0.985 * 0.985= 0.970225
b)
probability of one of system fail is = 1 - 0.985
=0.015
Therefore
probability of both system failing =0.015 * 0.015 =0.000225
probability at least one system function satisfactorily = 1- 0.000225
= 0.999775
c)
If both system are fail then probability is 0.000225
Jonas has 8, Maura has 24, and Treton has 6 I think. Hope it helps :)
Answer:
Option D: 1/3
Step-by-step explanation:
Let
x ------> the entire Stefanie's allowance
we know that
She spends on clothes (1/2)x
She spends on movies (1/6)x
To find out how much more does she spend on clothes that he does on movies, subtract the amount she spends on movies from the amount she spend on clothes
Simplify
therefore
She spends 1/3 more on clothes that he does on movies
I am looking on the answers, and there is only one case, when a or b or c or d pass: 3|x-3| + 2 = 14. So I assume, that before two is plus. Then:
3|x-3|+2=14 |minus 2
3|x-3|=12 |divide 3
|x-3|=4
From absolute value definition you've got two ways:
x-3=4 or x-3=-4
x=7 or x=-1
And answer d) passes
