Answer:
P ( Z < 72 ) = 0.8577 or P ( Z < 72 ) = 85.77 %
Step-by-step explanation:
We know:
-A normal distribution
-Mean μ = 69.0 in
-Standard deviation σ = 2.8 in
- Population n = 350
And doors height 72 in
If passengers will pass through the door without bending that means he must be under 72 in tall, therefore we are looking for the probability of men under 72 in, to find such probability we compute the value of Z according to
Z = ( X - μ ) / σ ⇒ Z = ( 72 - 69 ) / 2.8
Z = 1.07
Now with this value we look the Z tables, to find a value of: 0.8577
So the probability of select a men and that he can fit through the door is
P ( Z < 72 ) = 0.8577 or P ( Z < 72 ) = 85.77 %
Answer:
B
Step-by-step explanation:
(5, -1) and (-5, 2)
y=-3/10x+1/2
-1= 3/10 (5) + 1/2
-1 = -15/10 + 1/2
-1 = -1.5 + 0.5
-1 =-1
Salut!
Alecu ar citi in 12 zile 14 x 12 = 168 de pagini (atatea pagini are cartea);
O saptamana are 7 zile, asa ca 168 ÷ 7 = 24 de pagini trebuie sa citeasca zilnic Alecu ca sa inapoieze cartea la sfarsitul celor 7 zile;
Succes!
Answer:-8
Step-by-step explanation: you add -1+ -1, to get -2, then -2+-2, to get -4 and so forth.
