3^2 = 3 x 3 = 9

( 3^2 - 8 ) + 4

= 9 - 8 + 4

= 1 + 4

= 5

Answer:

(3^2-8) + 4 = 5

Step to step explanation:  

(3^2-8) + 4     (3^2 = 3 x 3)

(9 - 8) + 4

Answer:

x=20

Step-by-step explanation:

So we have [tex]\frac{x}{24} =\frac{30}{36}[/tex]

divide 30/36 to get

[tex]\frac{x}{24} =.833[/tex]

then multiply that by 24

[tex]x=.833*24[/tex]

which will get you

[tex]x=20[/tex]

The value of x from the given proportion is 20.

The given proportion is x/24 = 30/36.

Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Here, x/24 = 5/6

x/4 = 5/1

x=20

Therefore, the value of x from the given proportion is 20.

#SPJ6

Answer:

$24

Step-by-step explanation:

To begin we need to form an equation that equals the total amount of money, which is 56. The question tells us that Anitha's money and Jyothi's money comes to a sum of $56 (the total amount). So, in our equation we will be doing Anitha + Jyothi = 56; our equation will be 4x+2x+8=56.

The next step is to rearrange the equation to get x=..., and we can do this using the funnel method like I have shown in the attached image. First, I simplified to get 6x+8=56. Then, I subtracted 8 from both sides to get 6x=48. Finally, I divided by 6 on both sides to get x=8. This is the first step of the question completed.

The finish the question, we need to work out Jyothi's total money, and since we now know x=8, all we need to do is substitute 8 where x is for Jyothi. So, we need to calculate the answer to 2*8+8, and following the rules of BIDMAS, we get 24. Which is the final answer.

He made an error in step 1. Specifically, he distributed incorrectly.

The 3(x+2) portion is not the same as 3x+2. We need to multiply that '3' by the 2 as well to get 3*2 = 6

In other words, 3(x+2) should turn into 3x+6

If you wanted, you can think of 3(x+2) as three copies of (x+2) added together like this:  (x+2)+(x+2)+(x+2) = (x+x+x)+(2+2+2) = 3x+6

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.

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.
