Answer:
d. There is no charge
Step-by-step explanation:
An atom of this nature with equal number of protons and neutrons will have no charge on them.
Protons are the positively charged particles in an atomElectrons are negatively charged. Neutrons carry no charges.In an atom, when there is an imbalance between the number of protons and electrons, they become charged.
When the number of protons and electrons are the same, then, the atom becomes uncharged.
Charge = Number of protons - Number of electrons
Number of protons = 6
Number of electrons = 6
Charge = 6 - 6 = 0
So, the atom will have no charge on it.

We have 2 terms:
[tex]\sqrt{x+2}[/tex] and [tex]\sqrt{4x+1}[/tex]
For the sum of these to equal a negative number, in this case -3, one of these terms would have to be negative.
So what's the problem?The function [tex]\sqrt{x}[/tex] (square root of x) only returns positive values!
(See the attached image for a graph of [tex]\sqrt{x}[/tex])
Since neither of the terms can be negative, it can't be equal to -3. In other words, no matter what we put as [tex]x[/tex], we can't solve the solution, so we say that the equation does not have any solutions.

Johnny has a computer repair businesss and he needs to make at least $475 a day to remain in business. He charges an initial fee of $100, and $75 for each hour he works. How many hours must he work each day to remain profitable?
Subtract the fee from the total he needs:
475 - 100 = 375
Now divide that by the hourly rate:
375 / 75 = 5
He needs to work 5 hours.
2) Suppose the probability distribution for the one-period return of some asset is as follows: Return Probability 0.27 0.25* 0.18 0.25* 0.10 0.30 p.04 0.20+ a. What is this asset's expected one-period
The expected one-period return for the asset is given by the expression 0.0675 + 0.045 + 0.03 + 0.04p + 0.04, where 'p' represents an unknown probability.
The given probability distribution represents the one-period return for an asset, with corresponding probabilities assigned to each return value. To find the expected one-period return, we need to calculate the weighted average of the returns, where the weights are the probabilities.
Let's calculate the expected one-period return step by step:
1. Multiply each return value by its corresponding probability:
0.27 * 0.25 = 0.0675
0.18 * 0.25 = 0.045
0.10 * 0.30 = 0.03
p * 0.04 = 0.04p
0.20 * 0.20 = 0.04
2. Sum up the products calculated in step 1:
0.0675 + 0.045 + 0.03 + 0.04p + 0.04
3. Set the sum equal to the expected one-period return, denoted as E(R):
E(R) = 0.0675 + 0.045 + 0.03 + 0.04p + 0.04
Therefore, the expected one-period return of the asset is 0.0675 + 0.045 + 0.03 + 0.04p + 0.04.

a box has 10 disks numbered 1 through 10. a disk is drawn at random 50 times with replacement. the disk numbered 7 was drawn 6 times. what is the relative frequency of getting the disk numbered 7 on the next draw?
The relative frequency of getting the disk numbered 7 on the next draw is 0.12 or 12%.
To find the relative frequency of getting the disk numbered 7 on the next draw, we need to analyze the data provided.
In this scenario, a disk is drawn at random from a box containing 10 disks numbered 1 through 10. The draws are made with replacement, meaning that after each draw, the disk is returned to the box, and the next draw is independent of the previous ones.
We are given that the disk numbered 7 was drawn 6 times out of the 50 draws. To find the relative frequency of getting the disk numbered 7 on the next draw, we need to determine the proportion of times it appeared relative to the total number of draws.
The relative frequency can be calculated by dividing the number of times the desired outcome occurs (in this case, drawing disk 7) by the total number of trials (draws).
In this case, the number of times disk 7 was drawn is 6, and the total number of draws is 50. Therefore, the relative frequency is:
Relative frequency = (Number of times disk 7 was drawn) / (Total number of draws)
= 6 / 50
= 0.12
Hence, the relative frequency of getting the disk numbered 7 on the next draw is 0.12 or 12%.
This means that if we were to continue drawing disks with replacement, the probability of drawing disk 7 on the next draw would be approximately 12%. However, it's important to note that since the draws are made with replacement, the probability of drawing any specific disk remains the same for each draw, regardless of the previous outcomes.

A scientist counts the number of inclusions in a sample of 30 tourmaline rocks, each of weight 50g. a If the sample mean number of inclusions per gem is 31.0635 and the sample standard deviation of the number of inclusions is 2.0996, calculate the standard error of the mean number of inclusions. (Please provide answers rounded to four decimal places) Submit part Score: 0/1 Unanswered b) Use you answer from the previous question to estimate a 95% confidence interval for the mean number of inclusions per tourmaline gem (Please provide your answer to four decimal places).
a) To calculate the standard error of the mean number of inclusions, we divide the sample standard deviation by the square root of the sample size. In this case, the sample mean number of inclusions is 31.0635, and the sample standard deviation is 2.0996. The sample size is 30. Therefore, the standard error of the mean number of inclusions can be calculated as follows:
Standard Error = Sample Standard Deviation / √Sample Size
Standard Error = 2.0996 / √30 Standard Error ≈ 0.3836 (rounded to four decimal places) b) To estimate a 95% confidence interval for the mean number of inclusions per tourmaline gem, we can use the formula: Confidence Interval = Sample Mean ± (Critical Value × Standard Error) The critical value corresponds to a 95% confidence level, which is 1.96 for a large sample size. Using the standard error calculated in part (a) as 0.3836 and the sample mean of 31.0635, the confidence interval can be calculated as: Confidence Interval = 31.0635 ± (1.96 × 0.3836)
Confidence Interval ≈ 31.0635 ± 0.7521 Confidence Interval ≈ (30.3114, 31.8156) (rounded to four decimal places) Therefore, we can estimate with 95% confidence that the mean number of inclusions per tourmaline gem lies between approximately 30.3114 and 31.8156.

Which postulate or theorem can be used to determine the length of RT
Answer:
AAS Congruence Theorem
Step-by-step explanation:
The two triangles share the same vertex T. Therefore, both ∆s has the same measure of <T.
From the information made available in the diagram above, it shows that the non-included side of 170, and two given angles, <T and <S in ∆RST are congruent to the non-included side of 170, and two given angles, <T and <U in ∆VUT. Therefore, ∆RST and ∆VUT are both congruent to each other based on the AAS Congruence Theorem.
This invariably implies that the length of RT is congruent to the length of VT.

A person is starting a retirement fund. The person will add to the fund on a yearly basis. Each year, they will increase the amount added to the fund the previous year by 10%. In the first year, the person will add $2000. Which expression represents the total amount the person will add in the first 5 years?
A. 2000(1−1.1)^5/1−1.1
B. 2000(1−1.1^5)/1−1.1
C. 2000(1−.1)^5/.1
D. 2000(.1)^5/.1
The correct Retirement Fund expression is B. [tex]2000(1−1.1^5)/1−1.1.[/tex]
The expression that represents the total amount the person will add in the first 5 years is:
B. [tex]2000(1−1.1^5)/1−1.1[/tex]
Let's break down the expression to understand why it is the correct choice.
The person adds $2000 in the first year. Each subsequent year, they increase the amount added by 10% compared to the previous year. This means that in the second year, they will add 10% more than $2000, in the third year 10% more than what they added in the second year, and so on.
To calculate the total amount added in the first 5 years, we can use the formula for the sum of a geometric series:
S = a * [tex](1 - r^n)[/tex] / (1 - r)
where:
S is the sum of the series,
a is the first term,
r is the common ratio, and
n is the number of terms.
In this case, the first term a is $2000, the common ratio r is 1.1 (since each year's amount is 10% more than the previous year), and the number of terms n is 5 (since we want to calculate the total amount for the first 5 years).
Plugging these values into the formula, we get:
S = [tex]2000 * (1 - 1.1^5) / (1 - 1.1)[/tex]
Simplifying further, we get:
S = 2000 * (1 - 1.61051...) / (-0.1)
The approximate value of 1.61051... is obtained by evaluating 1.1^5.
This expression is equivalent to the expression in option B, [tex]2000(1−1.1^5)/1−1.1.[/tex]
Therefore, the correct Retirement Fund expression is B. [tex]2000(1−1.1^5)/1−1.1.[/tex]

The ratio of corresponding sides for the given similar triangles is 2/5.
In the given options, the ratio of corresponding sides is provided for each set of similar triangles. Let's analyze each option to determine the correct ratio:
a. 10
This option only provides a single number and does not specify the ratio of corresponding sides. Therefore, it is not the correct answer.
b. 4/5
This option provides the ratio 4/5 for the corresponding sides of the similar triangles. However, the ratio can be simplified further.
To simplify the ratio, we divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 4 and 5 is 1.
Dividing 4 and 5 by 1, we get:
4 ÷ 1 = 4
5 ÷ 1 = 5
Therefore, the simplified ratio is 4/5.
c. 10/85
This option provides the ratio 10/85 for the corresponding sides of the similar triangles. However, this ratio cannot be simplified further, as 10 and 85 do not have a common factor other than 1.
Therefore, the correct ratio of corresponding sides for the given similar triangles is 2/5, as determined in option b.
