Anitha and Jyothi shared some money. Anitha had $4x and Jyothi had $(2x + 8).
Both of them had $56 altogether. Find the value of x and hence find out how much
did Jyothi get?
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.
Suppose we know that a confidence interval is (27,35), with a margin of error of 4. Find the sample mean (x¯).
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.

Solve the following proportion x/24 = 30/36
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.

what iswrong with this one
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

Answer in 2 complete sentences.
Answer:
It is not necessary to line up decimals while multiplying because you count the decimals instead of bringing them down. Plus lining up decimals while adding can overcomplicate the problem with too many zeros.
