The most common error when entering a formula is to reference the wrong cell in the formula.

This error occurs when the cell references within a formula do not match the intended cells. It can lead to incorrect calculations and produce unexpected results. For example, if a formula is supposed to use data from cell A1 but mistakenly refers to cell B1, the calculation will be based on the wrong data. It is important to double-check and ensure that the cell references in a formula accurately reflect the intended data sources to avoid this common mistake.

Answer:

x =7

Step-by-step explanation:

hope it helped

Answer:

x=7

Step-by-step explanation:

i just saw that this has been answered but i want to give an explanation incase it is needed:

•3x+4=5x-10

first move the like terms to one side of the = sign. (its best to move the smaller x value to the bigger one.

•4+10=5x-3x

then you just solve the equation on both sides:

• 14=2x

then you have to being the 2 over the = sign so that x is by itself. when you bring a divide value over the = sign it will turn into the opposite operation.

so basically you are dividing 14 by 2

•14/2 = x or 14÷2=x

which finally gives you :

x=7

hope that makes sense...

1. Variable manufacturing overhead rate variance

The formula Actual Hours × (Actual Rate - Standard Rate) is used to calculate the variable manufacturing overhead rate variance. This variance measures the difference between the actual variable manufacturing overhead cost incurred and the standard variable manufacturing overhead cost that should have been incurred, based on the standard rate per hour.

Variable manufacturing overhead rate variance = Actual Hours × (Actual Rate - Standard Rate)

The variable manufacturing overhead rate variance provides insight into how efficiently a company is utilizing its variable manufacturing overhead resources in terms of the rate per hour. A positive variance indicates that the actual rate paid per hour for variable manufacturing overhead was higher than the standard rate, resulting in higher costs. On the other hand, a negative variance suggests that the actual rate paid per hour was lower than the standard rate, leading to cost savings.

By analyzing this variance, management can identify areas where the company may be overspending or underspending on variable manufacturing overhead and take corrective actions accordingly, such as renegotiating supplier contracts or optimizing resource allocation.

The three-course meals that are possible are 300.

To calculate how many three-course meals are possible, we need to calculate the total number of options. Since, you cannot have both dessert and appetizer, you have two options for the first course. Let's consider both these cases separately.

Case 1: Dessert

For the first course, there are six dessert option. After choosing a dessert, you are left with five soup option and five main course option. In this case, number of three-course meals possible are 6 * 5 * 5 = 150.

Case 2: Appetizer

For the first course, there are six appetizer option. After choosing an appetizer, you are left with five soup option and five main course option. In this case, number of three-course meals possible are 6 * 5 * 5 = 150.

Therefore, by adding up both the possibilities from both the cases, we have a total of 150 + 150 = 300 three-course meals possible.

Question 9.

In the construction of a frequency distribution, it is NOT a good idea to have overlaping class limits such as 10-20, 20-30, 30-40.

Let's determine if the above statement is true or false.

A frequency distribution shows a representation of the num ber of observations within a given interval either in tabular or grahical format.

In the construction of a frequency distribution, the class limits should be made very clear in order for each observation to fall into only one class.

It is not a good idea to have ovelaping class limits like 20-30, 30-40. This is because overlaping limits such as this would make it dificult to determine the class where 30 is located.

Therefore, this statement ''it is NOT a good idea to have overlaping class limits such as 10-20, 20-30, 30-40'' is TRUE.

Option C. No, because the 100 adults were selected without replacement, the selections are dependent.

The binomial probability formula assumes that the trials are independent, meaning that the probability of success or failure for each trial remains the same regardless of the outcomes of previous trials. However, in this case, the 100 adults were selected without replacement, so the probability of being left-handed for each selection depends on the outcomes of previous selections. Therefore, the binomial probability formula cannot be used to find the probability in this situation. Instead, the hypergeometric distribution can be used to account for the dependence between selections.

Complete question:

It is assumed that approximately 15% of adults in the U.S. are left-handed. Consider the probability that among 100 adults selected in the U.S., there are at least 30 who are left-handed. Given that the adults surveyed were selected without replacement, can the probability be found by using the binomial probability formula with x counting the number who are left-handed? Why or why not?

A. Yes, because the 100 adults represent less than 5% of the U.S. adult population, the trials can be treated as independent.

B. No, because the 30 adults represent more than 5% of the sample size, the trials are dependent.

C. No, because the 100 adults were selected without replacement, the selections are dependent.

D. No, because the probability of being right-handed is greater, x must count the number of right-handed adults.

Answer:

4 and 12

Step-by-step explanation:

let x be the smaller number and y the larger number , the

x + y = 4x ( subtract x from both sides )

y = 3x → (1)

2y - x = 20 → (2)

substitute y = 3x into (2)

2(3x) - x = 20

6x - x = 20

5x = 20 ( divide both sides by 5 )

x = 4

substitute x = 4 into (1)

y = 3x = 3 × 4 = 12

smaller number is 4 and larger number is 12

 (a) The probability that one woman using the birth control pill did not become pregnant is 0.98 (98% effective rate).(b) The formula that can be used to calculate the probability that at least one woman per 100 users will become pregnant is Pr = 1 - Pr.
 
(a) Given that the birth control pill is 98% effective, the probability that one woman using the pill did not become pregnant is 0.98. This means that there is a 98% chance of preventing pregnancy for an individual woman.
(b) To find the probability that at least one woman per 100 users will become pregnant, we can use the complement rule. The complement of "at least one woman per 100 users becoming pregnant" is "none of the 100 users becoming pregnant."The probability of "none of the 100 users becoming pregnant" can be calculated by multiplying the individual probabilities of each woman not becoming pregnant, assuming independence. Since each manifestation is independent, the probability for each woman not becoming pregnant is also 0.98.
Therefore, the probability that none of the 100 women become pregnant is (0.98)^100 ≈ 0.132, rounded to three decimal places.Using the complement rule, we can calculate the probability that at least one woman per 100 users will become pregnant as 1 - Pr(none of the 100 users become pregnant) = 1 - 0.132 ≈ 0.868, rounded to three decimal places. This is the probability that at least one woman per 100 users will become pregnant.

Answer:

A is the correct answer to the problem!

Answer:

Let's identify what we know and what we are looking for. To start off, the question states that there is a flat rate of 500. This is the y intercept, because you start off with 500. It also states that it charges a fee of 50 per hour, which is your slope. So what we have now is y=50x+500. We know that A is asking how much it will be for 20 hours. We simply plug 20 into x, so we do y=50(20)+500 which gives 1500. For C, we repeat the same step and just plug in 50.

Hello, sorry for taking half an hour to respond.

a) If x represents the number of students in her class, we have :

The cost of a calculator on website C : 480 : x
The cost of a calculator on website D : 480 : (x+4)

b) We call the price of a calculator on website C as a, and the price on website D is a-6
Let's also call the amount of calculators if we buy on website C as d, and the amount of calculators if we buy on website D as d + 4

We have :

a.d = (a-6)(d+4)
Break the brackets out : ad = ad-6d + 4a - 24
=> -6d + 4a - 24 = 0
Divide both sides by 2
=> -3d + 2a - 12 = 0

=> 2a = 3d + 12

So, d is divisible by 3, and a is divisible by 2 => ad is divisible by 6.

And ad x the amount of students = 480

So, we can conclude that the amount of students is a factor of 80

Let's list out all of them : 1,2,4,5,8,10,16,20,40,80.

If there was 20 students :

The price of each calculator would be : 480 : 20 = 24

If it's 6 cheaper, it would be 24-6 = 18

And she would've gotten 480 : 18 (not divisible)

If you keep replacing like that, you'll eventually get the answer. I don't have time left, so the answer is 16 students. Hope it helps.

The total cost of repayment over 5 years is $23,300.

A loan repayment refers to the act of paying back money previously borrowed from a lender.

To get total cost of repayment, we must principal amount, the interest rate and the duration of the loan.

The formula to get total cost of repayment is given by \(Total Cost of Repayment = Principal + Interest\)

Interest = Principal * Interest Rate * Time

Given:

Principal amount is $20,000

Interest rate is 3.3%

Duration is 5 years.

Interest = $20,000 * 0.033 * 5

Interest = $3,300

Total Cost of Repayment = Principal + Interest

= $20,000 + $3,300

= $23,300.
