Answer 1

Answer:

x + 8 = 20

Step-by-step explanation:

Using the keywords;

'more than' (addition)

'a number' which we can consider a variable

and 'equals'

Answer 2

Answer: 8 + x =20

Step-by-step explanation: eight more than a number means 8 more than meaning plus, a number. So this is saying that 8 more than what ever that number is, will equal 20. We say x in the equation because x can be see as “the number”.

x = “the number” = 12

This is because 8 more than 12 is 20...

So 8 more than a number = 8 + x = 20

Special right triangles please help!

Find the variable

Answers

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:

A popular video game claims that the average time needed to reach level 10 paladin is 3 hours with a standard deviation of 0.4 hours. james thinks that he and his four friends are more skilled than the average gamer because it took them an average of only 2.5 hours. which of the following is the most restrictive level that would validate his claim? upper-tail values a 5% 2.5% 1% critical z-values 1.65 1.96 2.58 1% 2.5% 5% 10%

Answers

The probability that the claim of James is correct is 1%.

What is a standard error?

The standard deviation of a statistic's sample distribution, or an approximation of that standard deviation, is its standard error. The standard error of the mean is the term used when the statistic is the sample mean.

In order to know if the claim of James is correct or not, firstly we need to determine the standard error. The standard error is the ratio of the standard deviation and the square root of the sample. Therefore, the standard error can be written as,

[tex]\rm Standard\ Error, SE =\dfrac{\sigma}{\sqrt n} = \dfrac{0.4}{\sqrt5} =0.178[/tex]

Thus, the standard error is 0.178.

Further, The z-score is defined as the distance from the sample to the population mean in units of standard error. Therefore, the z-score can be written as,

[tex]z = \dfrac{X-\mu}{SE}=\dfrac{(3- 2.5)}{0.178} = 2.81[/tex]

Using the Z-table in order to know the probability of the claim of James is correct or not, therefore, at this z-score, the probability is 0.9974≈1.00%.

Hence, the probability that the claim of James is correct is 1%.

A merchant bought a table for ₹8250 and spent ₹175 on its transportation. He
sold the table for ₹7500. Find its gain or loss?

Answers

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:

7500+175=7675

Btw, my teacher told me that the ans was 3. I'm kind of confused.

Answers

Answer:

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
