Please tell me how you got it very clearly



Any spam, nonsense, links, and anything that does not relate to this question will get deleted. Thank you.

Answers

So first you gotta convert 2 2/5 into and improper fraction which gives you 12/5. Which brings you to 12/5 x 5/7, you’re gonna wanna cross cancel the most common factor which is the number 5 and that leaves you to build up the fraction 12/7. Now you wanna convert your improper fraction to a mixed number, and you do that by putting it in long division form otherwise said as 12 divided by 7 which leaves you with 1 and a remainder of 5. 1 5/7 is your answer
If your problem is a fraction I can help… 1 5/7

Answer:

Apply the distributive property to the left-hand side of the inequality.

Step-by-step explanation:

Using PEMDAS, what you need to do first is clear!

P -> parentheses ( distribute, clear them out, etc. )

E -> exponents

M -> multiplication

D -> division

A -> addition

S -> subtraction

Going in order, you would apply the distributive property first to clear out the parentheses.

Suppose we know that a confidence interval is (27,35), with a margin of error of 4. Find the sample mean (x¯).

Answers

May u explain it alittle more im just confused

The formula for the sample mean, the margin of error, and the confidence interval.

Sample mean + margin of error = High-end confidence interval

Sample mean - margin of error = Low-end confidence interval

The sample mean is 31.

What is a mean?

It is the average value of the set given.

It is calculated as:

Mean = Sum of all the values of the set given / Number of values in the set

We have,

Confidence interval = (27,35).

The margin of error = 4.

The formula for the sample mean, the margin of error, and the confidence interval.

Sample mean + margin of error = High-end confidence interval

Sample mean - margin of error = Low-end confidence interval

Now,

The sample mean = x

x + 4 = 35 ____(1)

x - 4 = 27 _____(2)

From (1) we get,

x = 35 - 4 = 31

From (2) we get,

x = 27 + 4

x = 31

Thus,

The sample mean is 31.

Answer:

the line is at a 6.9 degree angle

Step-by-step explanation:

when the y = 69 the x = 420

Answer:

The answer is y = 1/8x

Step-by-step explanation:

Slope-intercept form is y = mx + b, with m being the slope and b being the y-intercept.

In this graph, we can see the line intersects the y-axis at point (0, 0). This means the y-intercept is 0, so we don't have to add it in the equation.

To find the slope, we use the formula m = (y₂ - y₁)/(x₂ - x₁) using two coordinate points on the line: (0, 0) and (8, 1).

Substituting it in the formula, we get m = (1 - 0)/(8 - 0), which simplifies to 1/8.

Putting this information into slope-intercept form, we get that the equation of the line in slope-intercept form is y = 1/8x.

Walmart marked up a bottle of nail polish 150% in order to make profit. if Walmart sells the nail polish for $8.75, what was the original cost of the polish?

Answers

The original price of the nail polish with a 150% markup sold at $8.75 is $3.50.

Let x be the original price of the polish.

Walmart marked up 150%.

Selling Price = Original Cost + Mark-up

therefore the selling price = x + 150% of x

we know the selling price is $8.75

Therefore, substituting the values:

8.75 = x + 150% of x

convert percentages to decimals:

8.75 = x + 1.5x

combine like terms:

8.75 = 2.5x

divide by 2.5 into both sides:

3.5 = x

use reflexive property:

x = $3.50

Thus, the original price of the nail polish is $3.50.
