24. Knowing a Person Who Was Murdered In a sample of 11,771 children
ages 2 to 17, 8% have lost a friend or relative to murder. Four children are
selected at random. (Adapted from University of New Hampshire)
(a) Find the probability that all four have lost a friend or relative to murder.
(b) Find the probability that none of the four has lost a friend or relative to
(c) Find the probability that at least one of the four has lost a friend or
relative to murder.
Using the binomial distribution, the probabilities are given as follows:
a) 0.000041 = 0.0041%.
b) 0.7164 = 71.64%.
c) 0.2836 = 28.36%.
For each person, there are only two possible outcomes, either they have lost a friend, or they have not. The probability of a person having lost a friend is independent of any other person, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula for the probability of x successes is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are given by:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.For this problem, the values of the parameters are:
n = 4, p = 0.08.
The probability of all four is P(X = 4), hence:
P(X = 4) = (0.08)^4 = 0.000041.
0.000041 = 0.0041% probability that all four have lost a friend or relative to murder.
The probability of none is P(X = 0), hence:
P(X = 0) = (0.92)^4 = 0.7164.
0.7164 = 71.64% probability that none have lost a friend or relative to murder.
The probability of at least one is given by:
P(X >= 1) = 1 - P(X = 0)
Then:
1 - 0.7164 = 0.2836.
0.2836 = 28.36% probability that at least one have lost a friend or relative to murder.

Points A and B have coordinates A(-4, 2) and B(3,-6). Find the coordinates of point P, the weighted average of points A and B, in which point A
has a weight of 2 and point 8 has a weight of 5.
A) (-2,-²)
B) (-2)
C) (1,-)
D) (1,-13)
Answer:
C) P(1, -26/7)
Step-by-step explanation:
You want the weighted average of A(-4, 2) and B(3,-6) using weights 2 and 5, respectively.
Weighted averageEach of the values is multiplied by the corresponding weight, and the sum of those products is divided by the total of the weights to obtain the weighted average.
P = (2A +5B)/(2+5)
P = (2(-4, 2) +5(3, -6))/7 = (-8 +15, 4 -30)/7 = (7, -26)/7
P = (1, -26/7)
The coordinates of P are (1, -26/7).

INTEREST FORMULA: The interest formula includes two types of interests - simple interest and compound interest. Interest is the cost a borrower pays a lender for a loan. This additional sum, or the interest, must be paid in addition to the loan itself. The compound interest formula and the simple interest formula are both discussed in the interest formula.
Present value of the car = A = $25,000
Depreciation rate = r = 30% per annum
Time = t = 1 year
Let the initial value be p
We know the formula, A = P(1 – r/100)^t
$25,000 = P [1 – 30/100] ^1
$25,000 = P (7/10)
P = (25,000 * 10) / 7
P = $35,714.3

Write the improper fraction 30/7 as a mixed number
Answer:
Step-by-step explanation:
30/7 = 4 2/7
Because 7 only goes into 30, four times (7 x 4 = 28) anything else would be too big.
7 goes into 30 four times, and you get left with a remainder of 2
So you write 4 wholes, then 2/7 because 2 is the remainder it goes on top, and 7 stays in the denominator (bottom)

a) "Reflect the graph about the x-axis."
This is written as:
g(x) = -f(x)
Replacing f(x) by the actual function:
g(x) = -x^2
b) "Vertical compress by a factor of 13"
This is written as:
g(x) = f(x)/13 = x^2/13
c) "Vertical shift up 2."
This is written as:
g(x) = f(x) +2 = x^2 + 2
d) "Horizontal shift right 3."
This is written as:
g(x) = f(x - 3) = (x - 3)^2
The graphs are below, the colors are:

Sports regulations usually give the sizes and weights of most sports equipment over a range of values. For each type of sports equipment, the diameters and weights to the appropriate type of ball are given in the accompanying table.
A box contains 30 baseballs. Write a compound inequality that shows the range of the weight of the balls. Graph the inequality.
Type of Ball Range of Diameters Range of Weights Tennis ball 2 1/2 inches to 2 5/8 inches no less than 2 ounces, no greater than 2 1/6 ounces Baseball 2 7/8 inches to 3 inches 5 to 5 1/4 ounces Basketball (women's) no less than 9.07 inches, no greater than 9.23 inches no less than 20 ounces, no greater than 22 ounces Soccer ball (size 5) no less than 21.64 inches, no greater than 22.28 inches 14.46 ounces to 15.87 ounces
The compound inequalities for all the balls that are sports regulated are { (x,y) : 2(1/2) ≤ x ≤ 2(5/8) and 2 ≤y≤ 2(1/6) } for Tennis ball.
{ (x,y) : 2(7/8) ≤ x≤ 3 and 5≤ y ≤ 5(1/4) } for Baseball.
{ (x,y) : 9.07 ≤ x ≤ 9.23 and 20 ≤ y ≤ 22 } for women's Basket ball.
{ (x,y) : 21.64 ≤x ≤ 22.28 and 14.46 ≤ y ≤ 15.87 } for Scoccer Ball.
What is the correct way of pronouncing a set in roaster form?Suppose we are given { (x,y) : 9.07 ≤ x ≤ 9.23 and 20 ≤ y ≤ 22 } this reads as The set of all x comma y such that x is between this range and y is between in this range.
Sports regulations have some rules that the diameters and weights of sports pieces of equipment must lie between the regulations that have been set.
We are denoting the Diameters of the balls as x in inches and the weights of the balls as y in ounces.
Now for a Tennis ball the range for x and y can be written in roaster form of set is { (x,y) : 2(1/2) ≤ x ≤ 2(5/8) and 2 ≤y≤ 2(1/6) }.
For Baseball it is { (x,y) : 2(7/8) ≤ x≤ 3 and 5≤ y ≤ 5(1/4) }.
For women's Basketball it is { (x,y) : 9.07 ≤ x ≤ 9.23 and 20 ≤ y ≤ 22 }.
For Soccer ball the set in roaster form can be written as
{ (x,y) : 21.64 ≤x ≤ 22.28 and 14.46 ≤ y ≤ 15.87 }.
