The probability that 2 out of 10 randomly selected shipments would be late is 0.19.
<h2>Given </h2>
A shipping company claims that 90% of its packages are delivered on time.
Jenny noticed that out of the last 10 packages shipped, 2 were late.
<h2>What is probability?</h2>
The probability of success and failure remain the same throughout the trials.
The probability that 2 out of 10 randomly selected shipments would be late is given by;
Hence, the probability that 2 out of 10 randomly selected shipments would be late is 0.19.

6. 2/3
7. Angle U = 56
8. SB = 15
Answer:
a.
b
Step-by-step explanation:
1.
Auxillary equation
D=2,2
Then complementary solution =
Particular solution 
D is replace by D+2 then we get
P.I=
P.I=
where V is a function of x
P.I=
By integrating two times
Hence, the general solution
b.y''+9y=5 cos x-7 sin x
Auxillary equation
D=
P.I=
P.I=
Then D square is replace by -a square
is replace by - then we get
P.I=-5 cos x+7 sin x
The general solution
Answer:
Step-by-step explanation:
I feature of congruence of triangles: side-side-side
Available two triangles must match equal sides, these triangles are congruent.
II feature of congruence of triangles side - angle - side
Available two sides and the angle contained between them in one triangle are equal to two sides and the angle contained between them in the other triangle, these triangles are congruent.
III feature of congruence of triangles angle - side - angle
If the side and two adjacent angles in one triangle, they are equal to the side and two adjacent angles of the other triangle, these triangles are congruent.
The answer would be choice B. "Five-year-old cat."
3 kilograms is about 6 pounds, which is reasonable for a cat of that age. It is reasonable to come to the conclusion that 6 pounds is too heavy for a peach or a small feather. Also, that would be far too light to be the weight of a grown elephant, given that they usually weigh a few tons.
