There is a bag filled with 4 blue, 3 red and 5 green marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of exactly 1 red?
Answer:
You are selecting marbles with replacement. The marble selections (trials) are independent and the marble selection follows the binomial distribution.
The probability of selecting a red marble the first time is 1313.
(This is because 4 out of 12 marbles are red and412412 reduces to 1313.
The probability of selecting a red marble the second time is 1313.
The marble selections are independent and you can multiply the two probabilities to get the following:
probability of getting 2 reds = (13)2(13)2
=19=19.
So the probability of getting two reds is 1919.

During a certain day, a worker made 81 parts. He usually does 45 parts per day. What was the percent by which he inrceased the number of parts he usually makes?
Answer:Percent Increase n the number of parts usually made = 80%
Step-by-step explanation:
Percent Increase = (Increase / Initial Number of parts made daily) X 100/1
Initial Number of parts made daily = 45
Current number of parts ,made daily = 81
Percent Increase = 81-45/ 45 x 100
=36/45 x100/1
= 0.8 x 100
= 80%
Answer:
80 percent

PLEASE HELP!Which of the following statements correctly describes how to tell when a function is positive over a given interval.
Question 5 options:
The functions values are greater than 0 over the interval.
The functions values are less than 0 over the interval.
Answer: The functions values are greater than 0 over the interval.
Step-by-step explanation:
To tell if a function is positive over a given interval, see if it's below the x-axis or if it's under (since the x-axis represents 0).
If it's below, it's less than zero. If it is above, it's greater than zero.If the interval is above the x-axis, it's positive (greater), and if it's below, it's negative (less).

Polynomial of degree 3 with three distinct real zeros and a positive leading coefficient
The Polynomial of degree 3 with three distinct real zeros and a positive leading coefficient is P(x) = x³ - x
Let the distinct real zeros of the required polynomial be 0, 1 and -1.
The equivalent factors will be x(x-1)(x+1)
To get the required polynomial, we will take the product of the factors as shown:
P(x) = x(x-1)(x+1)
P(x) = (x+1)(x-1)x
P(x) = x(x²-1)
P(x) = x³ - x
Hence the Polynomial of degree 3 with three distinct real zeros and a positive leading coefficient is P(x) = x³ - x
