This question is incomplete, the complete question is;
A fair coin is tossed three times and the events AA, BB, and CC are defined as follows: A:{A:{ At least one head is observed }} B:{B:{ At least two heads are observed }} C:{C:{ The number of heads observed is odd }} Find the following probabilities by summing the probabilities of the appropriate sample points (note that 0 is an even number): a) P(B) =, b) P(A or B) =
Answer:
a) probability of B is 0.5
b) probability of (A or B) is 0.875
Step-by-step explanation:
Given the data in the question;
The coin is tossed 3 times.
so let S represent the sample space with the probabilities;
S = [ HHH, HHT, HTH, THH, HTT, THT, TTH, TTT ]
so n(S) = 8
now let A be the set where at least one head is observed;
A = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]
n( A) = 7
let B be the set where at least two head is observed;
B = [ HHH, HHT, HTH, THH, ]
n(B) = 4
let C be the set where number of heads are odd;
C = [ HHH, HTT, THT, TTH ]
n(C) = 4
so
a) P(B) = ?
probability of B will be;
P(B) = n(B) / n(S)
we substitute
P(B) = 4 / 8 = 0.5
Therefore, probability of B is 0.5
b) P(A or B) = ?
the favorable number of cases to event A∪B is
A∪B = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]∪[ HHH, HHT, HTH, THH, ]
A∪B = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]
n(A∪B) = 7
Now the probability of A or B will be
P( A∪B ) = n(A∪B) / n(S) = 7/8 = 0.875
Therefore, probability of (A or B) is 0.875

Answers
The length of diagonal BD from the parallelogram ABCD is 10.
The midpoint of diagonals BD and AC is E. Hence, the point of bisection is marked E.
BE = DE (The diagonals of a parallelogram bisect each other)
From the diagram given :
BE = 5
DE = BE = 5
Length of BD = BE + DE
Length of BD = (5 + 5) = 10
Therefore, the length of Diagonal BD is 10.

Shoes cost $20 a pair and boots cost $60 a pair. Arlene and Jerry spent $8000 and bought 3 times as many boots as shoes. How many pairs of each did they buy?
Answers
Answer:
They bought 40 shoes and 120 boots.
Step-by-step explanation:
So from the question itself we can make the following equation.
Let "x" be the number of shoes they bought, then...
20(x) + 60(3x) = 8000
20x + 180x = 8000
200x = 8000
x = 8000 / 200
x = 40
From here we know that..
# of shoes they bought = x = 40
# of boots they bough = 3x = (3)(40) = 120

A leaky 10-kg bucket is lifted from the ground to a height of 12 m at a constant speed with a rope that weighs 0.5 kg/m. Initially the bucket contains 36 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 12-m level. Find the work done. (Use 9.8 m/s2 for g.) Show how to approximate the required work by a Riemann sum. (Let x be the height in meters above the ground. Enter xi* as xi.)
Answers
Answer:
The work done is 3645.6 J or 3.6 kJ
Step-by-step explanation:
M1 = (0.5 kg/m)(12 - x m) = (6 - 0.5x) kg
At the height of x meters (0<=x<=12), the mass of the rope is,
M2 = (36kg/12m)(12 - x m) = (36 - 3x m) kg
At the height of x meters (0<=x<=12), the mass of the water is,
M3 = 10 kg
The mass of the bucket is 10 kg
Then, Total mass M is,
M = M1 + M2 + M3 = (6 - 0.5x) + (36 - 3x) + 10 = (52 - 3.5x) kg
From Force F = mass m * acceleration due to gravity g
Force = mass x gravity
F = 9.8(52 - 3.5x) Newtons
To get the work done W,
Follow the attached file,
The work done is 3645.6 J or 3.6 kJ

Wilma has 28 coins, all nickels, and dimes worth $2.05. How many nickels does she have?
Answers
Answer:
15 nickels and 13 dimes
Step-by-step explanation:
5n + 10d = 205 cents
n + d = 28
n = 28-d
5(28-d) +10d = 205
140 -5d + 10d = 205
5d = 65
d = 13
n = 28-d = 28-13 = 15
5n = 5(15) = 75
10d = 10(13) = 130
75+130=205

To test the effectiveness of a new, cholesterol-lowering drug, a group of researchers recruits 200 volunteers with high cholesterol to take part in a study. The researchers place the numbers 1 through 200 in a hat and have each participant select a number. Those who picked an odd number receive the new drug, while those who picked an even number receive a placebo. Which experimental design are the researchers using?
a. Representative Sample Design
b. Completely Randomized Design
c. Matched-Pair Design
d. Randomized Block Design
Answers
Answer:
c. Matched-Pair Design
Step-by-step explanation:
The experimental research study showcased above exhibits two different treatments groups ; the new cholesterol lowering drug and the placebo. The allocation of observations or subjects into groups was based on pair selection which is based on whether subjects picked an even or odd number. Subjects who picked the odd are moved to the treatment group of the new drug while those who picked an even number are referred to the placebo treatment group. This type of research design which involves two pairs of treatment and allotment pattern is called a matched pair research design
Answer:
Completely Randomized Design

Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 16 feet, and the ball 2 is dropped from a height of 144 feet. Write and graph a function for the height of each ball. Then use the graphs to tell when each ball will reach the ground.
Answers
Answer:
Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 181 feet, and ball 2 is dropped from a height of 238 feet. Write a function for the height of each ball.
h1(t) = -16t^2 + 181
h2(t) = -16t^2 + 238
When does ball 1 reach the ground? Round to the nearest hundredth. seconds
Solve: -16t^2+181 = 0
-16t^2 = -181
t^2 = 11.3125
t = 3.3634 seconds

When does ball 2 reach the ground? Round to the nearest hundredth. seconds
