Mean for each hour = 1
Mean for four hours, m = 4
P(x,m)=m^x*e^(-m)/x!
where x is number of defects.
P(X<=3,4)
=P(X=0,4)+P(X=1,4)+P(X=2,4)+P(X=3,4)
=0.01832+0.07326+0.14653+0.19537
=0.43355
Probability of at most 3 defects in four hours is 0.43355
Answer:
y-5=-2(x+3)
Step-by-step explanation:
y-y1=m(x-x1)
m=-2
y-5=-2(x-(-3))
y-5=-2(x+3)
I think it would be 40% but i am not fursher i took 150 244 300 and 50 added them and subtracted them from 1240 and that gave me 496 496 % of 1240 is 40%
Answer: The correct option is (A). angle 1.
Step-by-step explanation: In the given diagram, the measure of ∠3 is 105°.
We are to find the angle that must also measure 120°.
We know that the measures of two vertically opposite angles are equal.
In the given diagram, since ∠1 and ∠3 are vertically opposite angles.
So, the measures of ∠1 and ∠3 are equal.
That is,
m∠1 = m∠3.
Also, m∠3 = 105°.
Therefore, m∠1 = 105°.
Thus, the measure of angle 1 must be 105°.
Option (A) is correct.
Not sure but good luck 25•
