Probability is the study of possible outcomes of events, together with the probabilities and distributions of those occurrences.
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
To calculate probability, divide the total number of outcomes by the total number of possible possibilities. There are differences between probability and odds.
Odds are computed by dividing the likelihood that an event will occur by the likelihood that it won't.
From the stated circumstance,
Total ways = [tex]4^{5}[/tex]= 1024

Yuri bought a new house. The diagram shows the layout of his backyard. Yuri is designing improvements that he wants to make. Yuri plans to fill the patio with concrete, the garden with a special soil mixture, and the remaining areas that surround the hot tub with a wood deck. The table shows the costs associated with each project. How much more will Yuri spend on concrete than on soil and wood? Explain. Click here to view the diagram of Yuri's backyard. Click here to view the table of materials. The area of the patio is yd?, so the cost of concrete is $ The area of the garden is yd?, so the cost of soil is $ The total area of the deck is ft?, so the cost of wood is $1. So, Yuri will spend $ more on concrete than on soil and wood. (Type integers or decimals.) Enter your answer in the edit fields and then click Check Answer. All parts showing
1) Area of patio = 1/2 base x height
Height = 3.1ft
base = 7 + 10 =17 ft
Area = 1/2 x 3.1 x 17
Area of patio = 26.35 square ft
1 yard = 3 ft
1 square yard = 9 square ft
so the area of the patio in yard is
26.35/9 = 2.927777778 square yard
2) Cost of concrete = $10/square yard poured 1/9 yard deep+ $60 delivery fee
for 2.9277777778 square yard it will cost 1/9($10 x 2.9277777778) + $60 =$

There are 54% of the participants are female.
What is percent?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
%, which is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified. percentage
Given:
There are 104 males and 121 females
participating in a marathon.
So, the total number of participants are,
104 + 121 = 225.
There are 225 total number of participants.
So, the percent of the female are,
[tex]\frac{121}{225} (100) = 53.78[/tex]

In comparative statistics, what type of error occurs when a test indicates a significant difference between two or more populations even though the null hypothesis is true?.
Type 1 error is the error occurs when a test indicates a significate difference between two or more populations.
What does a Type I mistake mean?Rejecting the null hypothesis when it is in fact true is a Type I mistake. It entails drawing conclusions about outcomes that are statistically significant when, in fact, they were just the consequence of chance or unrelated causes. The significance level you select (alpha or ) determines the likelihood that you will make this mistake.
Data cleansing—also known as data cleaning, data scrubbing, or data rectification—is the process of correcting inaccurate, insufficient, duplicate, or other wrong data in a data set. It entails locating data mistakes and then correcting them by modifying, updating, or eliminating data.
Using independent samples from two independent groups, the two-sample (independent groups) t-test is used to assess whether the unknown means of two populations are different from one another.

What is Marbles?
A marble is a tiny, sphere-shaped object that is frequently fashioned of agate, glass, clay, steel, or plastic. They come in a variety of sizes, but the most have a diameter of about 13 mm (12 in). These toys can be made into works of art or utilized in a variety of marble-based activities. They can also be used in races or runs. They are frequently collected for their pleasing colors and nostalgic appeal.
Let x = Number of red marbles
y = Number of black marbles.
A bag contains 275 marbles.
So, x + y = 275 ..(1)
There are 24 red marbles for every black marble.
x = 24y ..(2)
Plug value of x in equation (1).
24y + y = 275
25y = 275
y = 11

Ariel dropped a golf ball from her second story window. The ball starts from rest and hits the sidewalk 1.5 s later with a velocity of 14.7 m/s. Find the average acceleration of the golf ball.
The average acceleration of the golf ball as it was dropped from the second story window is 9.8m/s².
Given in the question is:
Since the ball started from rest
Initial velocity; u= 0m/s
Final velocity; v = 14.7 m/s
Time taken for the golf ball to hit the sidewalk; t = 1.5 s
Average Acceleration; g =?
To determine the average acceleration of the golf ball, we use the First Equation of Motion:
v = u + at
The Equation will be :
v = u + gt
Plug the all values in above equation:
14.7m/s = 0 + g x 1.5 s
g = 14.7 / 1.5
g = 9.8m/[tex]s^2[/tex]

Ms. Wilson invested $30,000 in two accounts, one yielding 8% interest and the
other yielding 9%. If she received a total of $2,590 in interest at the end of the
year, how much did she invest in each account?
The amount invested at 8% was $
The amount invested at 9% was $
Answer:
The amount invested at 8% was $11,000
The amount invested at 9% was $19,000
Step-by-step explanation:
Let the variable x represent the amount in $ invested at 8% and let y be the amount in $ invested at 9%
Total amount invested:
x + y = 30000 [1]
8% = 8/100 = 0.08
9% = 9/100 = 0.09
Interest at 8% on $x = 0.08x
Interest at 9% on $x = 0.09x
Total Interest :
0.08x + 0.09y = 2590 [2]
Using equations [1] and [2] we can solve for x and y
We have
x + y = 30000 [1]
0.08x + 0.09y = 2590 [2]
Multiply equation 1 by 0.08 to get
0.08x + 0.08y = 0.08(30,000)
0.08x + 0.08y = 2,400 [3]
Subtract [3] from [2] :
0.08x + 0.09y = 2590
-
0.08x + 0.08y = 2400
----------------------------------
0x + 0.01y = 190
Divide both sides by 0.01
0.01y/0.01 = 190/0.01
y = = 19,000
Use [1] to get value of x
x + y = 30,000
x + 19,000 = 30,000
x = 30,000 - 19,000
x = 11,000

A valid solution to a problem that vanished during the process of solving it is referred to as a missing solution.
We have to open the equation by using cross multiplication
10(3x - 3) = 15(x² - 1)

When line is reflected about x-axis, the x coordinate remain same where as y-coordinate changes in opposite sign with same magnitude. So reflection of line x = 3 about x axis remain same.
Simillarly reflection of line x = 3 about x = 1 remain same as x = 3.
The reflection of line x = 3 about y-axis results n a parallel line passing through x = -3.

Note also that upward and right movement is positive, downward and left movement is negative.
From the figure, the vertical units between two given points is 3 units upward, so this is positive.
The horizontal units between them is 2 units to the right which is also positive.
The slope will be :

How much of an increase does the new amount represent over the previous amount?
Based on the amount you have received in grants, and the amount the boss wants to increase it to, the increase the new amount represents over the previous amount is $15,000 or 33.3%.
How to find the increase?Your boss wants to increase the grants to $60,000 from the current amount of $45,000.
This means that the new amount will represent an increase over the previous amount by:
= 60,000 - 45,000
= $15,000
In percentage terms this is:
= Increase over previous amount / Previous amount x 100%
= 15,000 / 45,000 x 100%
= 33.3%
In conclusion, the difference between the grants applied for in the past 5 years and the amount the boss is asking for, gives the increase of $15,000.
