Every day Ahmet buys a scratch-off lottery ticket with a 40%, percent chance of winning some prize. He noticed that whenever he wears his red shirt he usually wins. He decided to keep track of his winnings while wearing the shirt and found that he won 3 out of 3 times. Let's test the hypothesis that Ahmet's chance of winning while wearing the shirt is 40%, percent as always versus the alternative that the chance is somehow greater.
Testing the hypothesis, it is found that the p-value of the test is 0.017 < 0.05, which means that we can conclude that the red shirt increases his chances of winning.
At the null hypothesis, we test if the proportion is of 40%, that is:
[tex]H_0: p = 0.4[/tex]
At the alternative hypothesis, we test if the proportion is greater than 40%, that is:
[tex]H_1: p > 0.4[/tex]
The test statistic is:
[tex]Z = \frac{X - p}{s}[/tex]
In which:
X is the sample proportion.p is the value tested at the null hypothesis.s is the standard error, given by:[tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex]
With n as the sample size.
In this problem:
0.4 is tested at the null hypothesis, thus [tex]p = 0.4[/tex].Won 3 out of 3, thus [tex]n = 3, X = \frac{3}{3} = 1[/tex].The standard error is:[tex]s = \sqrt{\frac{0.4(0.6)}{3}} = 0.283[/tex]
The value of the test statistic is:
[tex]Z = \frac{X - p}{s}[/tex]
[tex]Z = \frac{1 - 0.4}{0.283}[/tex]
[tex]Z = 2.12[/tex]
The p-value is the probability of finding a sample proportion of 1 or "above", which is 1 subtracted by the p-value of Z = 2.12.
Looking at the z-table, Z = 2.12 has a p-value of 0.983.1 - 0.983 = 0.017.The p-value of the test is 0.017 < 0.05, which means that we can conclude that the red shirt increases his chances of winning.

The equivalent expression will be;
⇒ 12 (2m + 3) + 6 (2m + 3)
Option D is true.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ (24m + 36) + (12m + 18)
Now,
Since, The expression is,
⇒ (24m + 36) + (12m + 18)
it can be written as;
⇒ (24m + 36) + (12m + 18) = 12 (2m + 3) + 6 (2m + 3)
Thus, The equivalent expression after solving,
⇒ 12 (2m + 3) + 6 (2m + 3)

Explain how you can take an imaginary number and multiply it by another imaginary
number and get a real number.
Answer:
When you multiply two imaginary numbers, you are essentially multiplying them by itself or squaring them. If we recall, an imaginary number is the square root of -1. By squaring this number, you're eliminating the square root, ending up with -1 (aka a real number).

A total of $8000 is invested: part at 5% and the remainder at 13%. How much is invested at each rate if the annual interest is $730?
Answer:
$3875 at 5%
$4125 at 13%
Step-by-step explanation:
Let x = amount invested at 5%.
Let y = amount invested at 13%.
x + y = 8000
0.05x + 0.13y = 730
Solve the first equation for x and sustitute into the second one to solve by the substitution method.
x = 8000 - y
0.05(8000 - y) + 0.13y = 730
400 - 0.05y + 0.13y = 730
0.08y = 330
y = 4125
x = 8000 - 4125
x = 3875
Answer:
$3875 at 5%
$4125 at 13%

Which of the following describes a gerund and how it functions in a sentence? (1 point)
O A gerund is a noun that functions as the subject of a sentence.
O A gerund is a noun that functions as the direct object receiving the action in a sentence.
O A gerund is a verb ending in -ing that functions as a verb in a sentence.
O A gerund is a verb ending in -ing that functions as a noun in a sentence.
Answer:
a
Step-by-step explanation:
The accurate definition of the gerund and its purposes is "gerund is a verb ending in -ing that serves as a noun in a phrase." Thus, option fourth is correct.
What is sentence?Sentence refers to a set of words that are appropriately ordered in a line and provide the sense or meaning. When the line imparts meaning to the words, it is considered to be a sentence.
A combination of words that may transmit a statement, question, exclamation, or demand on their own. Sentences generally include a subject and a predicate, as well as one main clause and one or more subsidiary clauses.
Gerund is a verb form that includes -ing at the end of the word and functions as a noun in the phrase. Gerunds, like the other two forms of verbals, are founded on a verb and hence reflect the verbal category.
Therefore, it can be concluded that option fourth is correct.

Proof Hexagon:
Hey, I'm a German 11th grader and we currently have a tough geometry question: The centers A, B, C of three congruent circles that have no common points do not lie on the same straight line. From points A, B, C, the six tangents shown in the figure are placed on the circles that enclose a convex hexagon.Prove: The sums of the lengths of three pairs of not immediately adjacent sides of this hexagon are equal, i.e. | PQ | + | RS | + | TU | = | QR | + | ST | + | UP |
How can I prove this? I already found out that the triangles on the sides of the hexagon are not pairwisely congruent, as i first thought. I think my other idea that the red and orange triangles (attachment) are congruent, so the sum of the areas of the triangles on the above mentioned sides is equal, but the congruency of red and orange must be proven too. Any help is appreciated!
If I'm not wrong, then the answer will be:-
Given
• centers A, B, C
• three congruent sides
• have no common points
So, the result is:-
| PQ | + | RS | + | TU | = | QR | + | ST | + | UP |

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
- |a + b| / 2 - c
The value of -|a + b| / 2 - c
when,
a = [tex]1\frac{7}{8}[/tex] = 15/8
b = -1
c = -4
= [- |a + b| / 2 ]- c
= [ - | 15/8 + (-1) | / 2] - (-4)
= [ - | 15/8 - 1 | / 2 ] + 4
= [ - | (15-8)/8 | / 2 ] + 4
= [ - | 7/8 | / 2 ] + 4
= { -7/(8 x 2) ] + 4
= -7/16 + 4

There is a 1 in 8 chance of a player winning a game. Which value is equivalent to the chance
of the player winning a game?
F
100
125
G
125
10
H 1.25
J 0.125
The value which is equivalent to the 1 in 8 chance of the player winning a game is Choice J: 0.125.
The question statement implies that the probability of a player winning a game is 1 in 8.
We must know that the probability of an event occuring can be expressed as any choice of real numbers. However, the probability must ultimately not be more than 1 upon evaluation.
For choice F:
The expression 100/125 = 0.8 which is not equivalent to 1 in 8.For choice G:
The expression 125/10 = 12.5 which is not equivalent to 1 in 8.For choice H:
The expression 1.25 is more than 1, therefore, it is obviously not equivalent to 1 in 8.For Choice J:
The expression 0.125 is equivalent to 1 in 8 because 1/8 = 0.125.Read more:
