Answer:

The approximate probability that the total weight of their baggage

P (\bar x >60) = 0.000

Step-by-step explanation:

Given data;

number of passenger is 100

baggage limit = 6000 lb

standard deviation = 19 lb

mean value  = 49

For 100 passengers baggage limit is 6000 lb

so, average weight for per passenger  > 60

P (\bar x >60)

As mean value is 49, therefore  P (\bar x >60) lie on right side center

z is given as

z = \frac{ \bar x \mu}{\sigma_{\bar x}}

z = \frac{60 - 49}{\frac{\sigma}{\sqrt n}}

z  = \frac{60 - 49}{\frac{19}{\sqrt {100}}} = 5.79

P(Z>5.79) = AREA to the right of 5.79

P (\bar x>60)  = P (Z>5.79)  = 1 -P (Z < 5.79)

= 1 -P (Z < 5.79)

= 1 - 1.0000

= 0.000

P (\bar x >60) = 0.000

What is the solution to the system shown below y=2x-1. Y=2x+3 A (0,0). B(1,-3) C(-1,3). D no solution
Setler [38]
We have that
<span>y=2x-1
and
Y=2x+3
the two lines are parallel
because the slopes are the same
m=2

we know that
</span>If two lines are parallel<span>, then they will never intersect
</span><span>
therefore
the answer is the option
</span><span>D no solution</span><span>
