Answer:
b= -11
Step-by-step explanation:
For an equation to remain valid, what we do to the right- hand side of the equation should also be done to the left- hand side of the equation.
5b= -55
Since we are finding the value of b, we need to divide the right- hand side by 5 to obtain b from 5b. Thus, divide the left- hand side by 5 too.
b= -55 ÷5
b= -11

the mean per capita consumption of milk per year is 105 liters with a standard deviation of 26 liters. if a sample of 220 people is randomly selected, what is the probability that the sample mean would be less than 107.81 liters? round your answer to four decimal places.\
Answers
The probability is approximately 0.9429. Rounded to four decimal places, the probability is 0.9429. Therefore, the probability that the sample mean would be less than 107.81 liters is about 0.9429 or 94.29%.
To solve this problem, we can use the central limit theorem, which states that the distribution of sample means will be approximately normal with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.
First, we need to calculate the standard error of the mean, which is the standard deviation of the sampling distribution of the mean:
standard error = standard deviation / square root of sample size
standard error = 26 / sqrt(220)
standard error ≈ 1.756
Next, we can standardize the sample mean using the formula for z-scores:
z = (sample mean - population mean) / standard error
z = (107.81 - 105) / 1.756
z ≈ 1.574
Finally, we can use a standard normal distribution table or calculator to find the probability of getting a z-score less than 1.574.

Answers
The Deposit Fees 15% VAT amount on goods sold at a VAT-inclusive price of R1,500 would be approximately R195.65.
To answer the questions using the provided information, we'll refer to TABLE 2 for the deposit fees.1.2.1 The minimum amount one will pay when making a deposit of notes and coins:
Notes: R2.25 per R100 or part thereof
Coins: R5 per R100 or part thereof
Therefore, the minimum amount one will pay depends on the value of the deposit. For notes, it will be R2.25 per R100 or part thereof, and for coins, it will be R5 per R100 or part thereof.
1.2.2 To determine if Mr Mbhalati's statement is valid, let's calculate the deposit fees for his deposit of notes and coins.
Deposit of notes:
Deposit amount: R1,500
Deposit fee for notes: R2.25 per R100 or part thereof
Calculation:
Deposit fee = (Deposit amount / 100) * Deposit fee per R100
= (1500 / 100) * 2.25
= 33.75
Deposit of coins:
Deposit amount: R500
Deposit fee for coins: R5 per R100 or part thereof
Calculation:
Deposit fee = (Deposit amount / 100) * Deposit fee per R100
= (500 / 100) * 5
= 25
Total deposit fee = Deposit fee for notes + Deposit fee for coins
= 33.75 + 25
= 58.75
Therefore, Mr Mbhalati's statement is not valid. The total deposit fee for his deposit of notes to the value of R1,500 and R500 in coins would be R58.75, not R180.
1.2.3 To calculate the 15% VAT on the amount of goods sold at a VAT-inclusive price:
Amount from the sale of goods: R1,500
Calculation:
VAT amount = (Amount from the sale of goods / (100 + VAT rate)) * VAT rate
= (1500 / (100 + 15)) * 15
= (1500 / 115) * 15
≈ 195.65
Therefore, the Deposit Fees 15% VAT amount on goods sold at a VAT-inclusive price of R1,500 would be approximately R195.65.
1.2.4 One method Mr Mbhalati can use to send money to a person who does not have a bank account is by using a money transfer service like Western Union or MoneyGram. These services allow individuals to send money to recipients who can collect it in cash from designated locations, even if they don't have a bank account.

The claim that the population mean is less than 125 (Option E) would
the interval tends to refute.
How to know which claim would the interval tends to refute?The 90% confidence interval for the population mean is 135 to 160. This means that if we were to repeat the process of taking samples from the same population and constructing a 90% confidence interval, we would expect 90% of the intervals to contain the true population mean.
With this in mind, let's consider each claim:
A. The interval does not rule out the possibility that the population mean is more than 110, as 110 is less than the lower bound of the interval.
B. The interval does not rule out the possibility that the population mean is less than 150, as 150 is greater than the upper bound of the interval.
C. The interval does not rule out the possibility that the population mean is between 140 and 150, as both of these values fall within the interval.
D. The interval does not rule out the possibility that the population mean is more than 140, as 140 is less than the upper bound of the interval.
E. The interval refutes the claim that the population mean is less than 125, as 125 is less than the lower bound of the interval.

Explain two factors that could make the public resort to violent ways of protesting
Answers
There are a variety of factors that can lead to violent protests, but two significant factors are perceived injustice and lack of political representation.
Perceived injustice: When people feel that they have been wronged, marginalized, or oppressed by a system or institution, they may resort to violent protest as a way to express their anger and frustration. This is particularly true when people believe that peaceful means of protest have been ignored or have failed to bring about change. For example, if a community feels that they are being unfairly treated by the police, and previous attempts to seek redress through peaceful protests or other channels have failed, they may turn to violent protest as a last resort.
Lack of political representation: When people feel that their voices are not being heard, they may resort to violent protests as a way to force attention to their concerns. This can happen when marginalized groups feel excluded from the political process, or when they feel that their interests are being ignored by those in power. If people feel that their concerns are not being taken seriously, they may turn to violent protest as a way to make their voices heard.

expres
Answers
The postfix expression of "7+5-3*2(6*7)/4" is "7 5 + 3 2 * 6 7 * 2 * - 4 /". Evaluating the postfix expression gives the result of the expression. The prefix expression for the given infix expression is "/ - + 7 5 * 3 * 2 ( * 6 7 ) 4".
To convert the infix expression "7+5-3*2(6*7)/4" into postfix expression, we follow the rules of operator precedence and associativity. The postfix expression is obtained by placing operators after their operands.
The postfix expression for the given infix expression is:
"7 5 + 3 2 * 6 7 * 2 * - 4 /"
To evaluate the postfix expression, we use a stack data structure. We scan the postfix expression from left to right and perform the corresponding operations.
Starting with an empty stack, we encounter the operands "7" and "5". We push them onto the stack. Then we encounter the operator "+", so we pop the last two operands from the stack (5 and 7), perform the addition operation (7 + 5 = 12), and push the result back onto the stack.
We continue this process for the remaining operators and operands in the postfix expression. Finally, after evaluating the entire expression, the result left on the stack is the final answer.
To convert the infix expression into prefix expression, we follow similar rules but scan the expression from right to left. The prefix expression is obtained by placing operators before their operands.
The prefix expression for the given infix expression is:
"/ - + 7 5 * 3 * 2 ( * 6 7 ) 4"

If the conclusion of an argument is a tautology, then the counterexample set of that argument must be inconsistent. True or False?
Answers
The statement "If the conclusion of an argument is a tautology, then the counterexample set of that argument must be inconsistent" is true.
Let's understand why?
Explanation:
An argument with a tautology conclusion is an argument that arrives at a conclusion that is always true, regardless of the truth values of the premises. In other words, it is impossible for the premises to be true while the conclusion is false.
This means that any attempt to find a counterexample that disproves the conclusion will always fail, as there is no possible scenario in which the conclusion is false.
The counterexample set of an argument is the set of all possible scenarios in which the premises are true but the conclusion is false. If the conclusion is a tautology, then there is no possible scenario in which the conclusion is false, and thus the counterexample set is empty. An empty counterexample set is equivalent to an inconsistent counterexample set, as it means that there is no consistent scenario in which the conclusion is false.
Therefore, if the conclusion of an argument is a tautology, then the counterexample set of that argument must be inconsistent.
Hence, the statement is true.

John opened up a new bag of jelly beans and ate three-fourths of the jelly beans in the bag. Then Mike ate two-thirds of the remaining jelly beans. Finally, Fred ate the ten jelly beans that were left. How many jelly beans were in the unopened bag of jelly beans?
Answers
There were 60 jelly beans in the unopened bag of jelly beans.
Let's work through the problem step by step to find the original number of jelly beans in the bag.
John ate three-fourths of the jelly beans.
This means that he consumed 3/4 of the total number of jelly beans, leaving 1/4 of the original amount.
Mike then ate two-thirds of the remaining jelly beans.
Since 1/4 of the original amount was left after John, Mike ate 2/3 of this remaining 1/4.
To find out how much is left, we need to calculate \((\frac{1}{4} )\times (\frac{2}{3} )\).
\((\frac{1}{4} )\times(\frac{2}{3} )=\frac{2}{12} =\frac{1}{6}\)
Mike ate 1/6 of the original amount, leaving 1/6 of the original amount.
Finally, Fred ate the ten jelly beans that were left.
We know that these ten jelly beans represent 1/6 of the original amount.
Let's calculate how many jelly beans are equal to 1/6.
\(\frac{1}{6} = 10\) jelly beans
Now, we can determine how many jelly beans are equal to 6/6 (the whole).
\(\frac{1}{6} \times6=10\times6=60\) jelly beans
Therefore, there were 60 jelly beans in the unopened bag of jelly beans.
