Step-by-step explanation:
20 percent of 15 is 3, so if there were to be 20 percent off, the answer would be 12.
Answer:
$12
Step-by-step explanation:
Given:
$15 sale
Sale: 20% off
New cost of the shirt

The sides of a triangle are 20, 51, and 50. Use the Pythagorean Theorem to determine if the triangle is right, acute, or obtuse. The triangle is because the square of the largest side the sum of the squares of the other two sides.
Answer: Obtuse Triangle
Step-by-step explanation:
It is not right, because a^2 + b^2 doesn’t equal c^2. It is Actually obtuse because a^2 + b^2 is greater than c^2 because 20^2+50^2 =2900 which is greater than 2601 or 51^2.

Question:
A party pack consists of x chocolate bars and x cans of drinks. Each chocolate bar costs $3 and each can of drink costs $1. The total cost for the chocolate bars and drinks in a party pack is more than $10. Find the minimum number of choclate bars in a party pack.
Btw, my teacher told me that the ans was 3. I'm kind of confused.
Answer:
3
Step-by-step explanation:
Your teacher is correct. The reason is because it is the total cost of both the chocolate and the can… if the choc is $3 and can is $1, you can have 3 chocolate bars because when you add the one can which is one dollar, it equals $10
3x3 = 9
9+1 = 10
Therefore 3 is the answer

a probability of zero means it can never happen
a probability of one means it will always happen
Answer:
B.
Step-by-step explanation:
I assume the middle two choices have fractions 1/2 and 9/10.
In probability, 1 means it will definitely happen. 0 means it will definitely not happen.

Special right triangles please help!
Find the variable
Answer:
11. s = 14
12. k = 24
Step-by-step explanation:
There are two "special" right triangles that show up in trig and geometry problems.
The isosceles right triangle has angles of 45°-45°-90°, and side length ratios 1 : 1 : √2.
The half-equilateral triangle has angles of 30°-60°-90°, and side length ratios 1 : √3 : 2.
You will do yourself a favor if you remember and learn to recognize these triangles.
__
11.)The hypotenuse of the isosceles right triangle is 14√2. This tells you the basic ratio has been multiplied by 14. The side length is ...
s = 14
__
12.)The half-equilateral triangle has middle-length side 12√3. This means the basic ratio has been multiplied by 12. The triangle short side is 12, and the long side is twice that:
k = 24

The volume of this right prism is 240.5 ft³. What is the height, x, of the prism? Enter your answer as a decimal in the box.
Answer:
7.4 is the correct answer
Step-by-step explanation:
Height 'x' of the given right prism is 7.4 feet.
Volume of right prism:What information do we have?
Height of base = 5 ft
Length of first parallel line = 5 ft
Length of Second parallel line = 8 ft
Volume of prism = 240.5 ft³
Volume of prism = Area of base × height
Volume of prism = (1/2)(sum of parallel line)(Height) × height
240.5 = (1/2)(5+8)(5) × height
240.5 = (1/2)(13)(5) × height
240.5 = 32.5 × height
Height of prism = 7.4 feet

A merchant bought a table for ₹8250 and spent ₹175 on its transportation. He
sold the table for ₹7500. Find its gain or loss?
Answer: Loss of 925
==============================================
Work Shown:
Total cost = 8250+175 = 8425
Total revenue = 7500
Profit = revenue - cost = 7500 - 8425 = -925
Profit = -925
The negative profit means the merchant lost money.
Answer: The merchant lost 575 dollars or whatever you call them.
Step-by-step explanation:

Which of the following z-values, standard deviations, and sample sizes produce a margin of error of 0.95? m e = startfraction z times s over startroot n endroot endfraction z = 2.14; s = 4; n = 9 z = 2.14; s = 4; n = 81 z = 2.14; s = 16; n = 9 z = 2.14; s = 16; n = 81
The z-values, standard deviations, and sample sizes that produce a margin of error of 0.95 is z = 2.14; s = 4; n = 81.
What is the margin of error?The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The formula of the margin of error is given by the formula,
[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]
A.) z = 2.14; s = 4; n = 9
The margin of error is,
[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]MOE = 2.14\times \dfrac{4}{\sqrt{9}}\\\\\\MOE =2.85[/tex]
B.) z = 2.14; s = 4; n = 81
The margin of error is,
[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]MOE = 2.14\times \dfrac{4}{\sqrt{81}}\\\\\\MOE =0.9511[/tex]
C.) z = 2.14; s = 16; n = 9
The margin of error is,
[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]MOE = 2.14\times \dfrac{16}{\sqrt{9}}\\\\\\MOE =11.413[/tex]
D.) z = 2.14; s = 16; n = 81
The margin of error is,
[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]MOE = 2.14\times \dfrac{16}{\sqrt{81}}\\\\\\MOE =3.80[/tex]
