Answer:
We use Newton's second law of motion, which states that,
F
=
m
a
where:
F
is the net force applied in newtons
m
is the mass of the object in kilograms
a
is the acceleration of the object in meters per second squared
So, we get:
F
=
5
kg
⋅
10
m/s
2
=
50
N
(
∵
1
N
≡
1
kg m/s
2
)
Step-by-step explanation:
The odds against selecting a red marble is =2/11
<h3>Calculation of probability</h3>
The number of marbles which were red = 9
The number of marbles which were blue = 2
The total amount of marbles in the Box = 11
When one marble is picked at random from the box, the odds against selecting a red marble can be gotten through the blue marble.
That is, the number of blue marble/ total marble
= 2/11

not a clue luv sorry xxxx
Answer:
Expected Number=71
Variance =4959
Standard Deviation= 70.42
Step-by-step explanation:
Expected Number = E (x) = np
Here p = 0.71 and q= 1- 0.71= 0.29 n= 100
Expected Number = E (x) = np = 0.71*100= 71
b) The Variance and Standard Deviation for the number of these tweets with no reaction
Suppose the number of tweets are hundred then the number of tweets with no reaction would be 71 .
Variance = E(x²) - [E(x)]² = (100)²- (71)²= 10000- 5041= 4959
Standard Deviation= √4959= 70.42
