A speaker claimed that if the number of factories in the country increases by 3% per annum, then even if they all immediately reduced the amount of pollution they produce by 80%, the total annual pollution will be back to its present level in about 50 years. (Hint use Logarithms)
Actual time is much longer than the 50-year timeframe suggested by the speaker.
How to verify the statement?
This claim is based on the assumption that the rate of pollution reduction from each factory remains constant at 80%, and the number of factories increases by 3% per annum.
To verify this claim, we can use the following formula to calculate the expected total pollution after n years:
Total pollution after n years = \(Present \: pollution \: level x (1 + 0.03)^n \times (1 - 0.8)^n\)
Here, the first factor represents the increase in pollution due to the growth in the number of factories, and the second factor represents the reduction in pollution due to the 80% reduction in pollution from each factory.
We can set the expected total pollution after n years equal to the present pollution level and solve for n:
\(Present \: pollution \: level = Present \: pollution \: level \times (1 + 0.03)^n \times (1 - 0.8)^n\)
Simplifying this equation, we get:
\(1 = 1.03^n \times 0.2^n\)
Taking the logarithm of both sides of the equation, we get,
\(n \times log(1.03) + n \times log(0.2) = 0 \\ n \times (log(1.03) + log(0.2)) = 0 \\ n = \frac{0} { (log(1.03) + log(0.2))} \\ n = 271.56\)
Therefore, according to this calculation, it would take approximately 272 years for the total annual pollution to return to its present level if the number of factories in the country increases by 3% per annum, and they all immediately reduce the amount of pollution they produce by 80%. This is much longer than the 50-year timeframe suggested by the speaker.
It is important to note that this calculation assumes that the pollution reduction from each factory remains constant at 80% and does not take into account any other factors that may affect pollution levels, such as changes in technology or regulations. Therefore, this should be considered as a rough estimate and not as an exact prediction.

Decide whether the rates are equivalent. Maria saves $50 in 4 months.
Ralph saves $60 in 5 months
Answer:
The rates are not equivalent since Maria saves $0.50 more per month than Ralph.
Step-by-step explanation:
We can determine if two rates are equivalent by comparing the rates at which they save per month.
Maria's savings per month:
Both 50 and 4 can be divided by 2, which gives us 25/2. As a regular number, this becomes 12.5/1 which means Maria saves $12.5 per month.
Ralph's savings per month:
Both 60 and 5 can be divided by 5, which gives us 12. Thus, Ralph saves $12 per month.
Thus, the rates are not equivalent as Maria saves $0.50 more per month than Ralph.

Answer:

Step-by-step explanation:
Given
\(\begin{array}{ccccccccccccccc}{1} & {[ \ ]} & {4} & {[ \ ] } & {15} & {18}& {[ \ ] } & {[ \ ]} & {29} & {30} & {32} & {[ \ ]} & {58} & {[ \ ]} \\ \end{array}\)
Required
Fill in the box
From the question, the range is:
\(Range = 60\)
Range is calculated as:
\(Range = Highest - Least\)
From the box, we have:
\(Least = 1\)
So:
\(60 = Highest - 1\)
\(Highest = 60 +1\)
\(Highest = 61\)
The box, becomes:
\(\begin{array}{ccccccccccccccc}{1} & {[ \ ]} & {4} & {[ \ ] } & {15} & {18}& {[ \ ] } & {[ \ ]} & {29} & {30} & {32} & {[ \ ]} & {58} & {61} \\ \end{array}\)
From the question:
\(IQR = 20\) --- interquartile range
This is calculated as:
\(IQR = Q_3 - Q_1\)
\(Q_3\) is the median of the upper half while \(Q_1\) is the median of the lower half.
So, we need to split the given boxes into two equal halves (7 each)
Lower half:
\(\begin{array}{ccccccc}{1} & {[ \ ]} & {4} & {[ \ ] } & {15} & {18}& {[ \ ] } \\ \end{array}\)
Upper half
\(\begin{array}{ccccccc}{[ \ ]} & {29} & {30} & {32} & {[ \ ]} & {58} & {61} \\ \end{array}\)
The quartile is calculated by calculating the median for each of the above halves is calculated as:
\(Median = \frac{N + 1}{2}th\)
Where N = 7
So, we have:
\(Median = \frac{7 + 1}{2}th = \frac{8}{2}th = 4th\)
So,
\(Q_3\) = 4th item of the upper halves
\(Q_1\)= 4th item of the lower halves
From the upper halves
\(\begin{array}{ccccccc}{[ \ ]} & {29} & {30} & {32} & {[ \ ]} & {58} & {61} \\ \end{array}\)
We have:
\(Q_3 = 32\)
\(Q_1\) can not be determined from the lower halves because the 4th item is missing.
So, we make use of:
\(IQR = Q_3 - Q_1\)
Where \(Q_3 = 32\) and \(IQR = 20\)
So:
\(20 = 32 - Q_1\)
\(Q_1 = 32 - 20\)
\(Q_1 = 12\)
So, the lower half becomes:
Lower half:
\(\begin{array}{ccccccc}{1} & {[ \ ]} & {4} & {12 } & {15} & {18}& {[ \ ] } \\ \end{array}\)
From this, the updated values of the box is:
\(\begin{array}{ccccccccccccccc}{1} & {[ \ ]} & {4} & {12} & {15} & {18}& {[ \ ] } & {[ \ ]} & {29} & {30} & {32} & {[ \ ]} & {58} & {61} \\ \end{array}\)
From the question, the median is:
\(Median = 22\) and \(N = 14\)
To calculate the median, we make use of:
\(Median = \frac{N + 1}{2}th\)
\(Median = \frac{14 + 1}{2}th\)
\(Median = \frac{15}{2}th\)
\(Median = 7.5th\)
This means that, the median is the average of the 7th and 8th items.
The 7th and 8th items are blanks.
However, from the question; the mode is:
\(Mode = 18\)
Since the values of the box are in increasing order and the average of 18 and 18 do not equal 22 (i.e. the median), then the 7th item is:
\(7th = 18\)
The 8th item is calculated as thus:
\(Median = \frac{1}{2}(7th + 8th)\)
\(22= \frac{1}{2}(18 + 8th)\)
Multiply through by 2
\(44 = 18 + 8th\)
\(8th = 44 - 18\)
\(8th = 26\)
The updated values of the box is:
\(\begin{array}{ccccccccccccccc}{1} & {[ \ ]} & {4} & {12} & {15} & {18}& {18 } & {26} & {29} & {30} & {32} & {[ \ ]} & {58} & {61} \\ \end{array}\)
From the question.
\(Mean = 26\)
Mean is calculated as:
\(Mean = \frac{\sum x}{n}\)
So, we have:
\(26= \frac{1 + 2nd + 4 + 12 + 15 + 18 + 18 + 26 + 29 + 30 + 32 + 12th + 58 + 61}{14}\)
Collect like terms
\(26= \frac{ 2nd + 12th+1 + 4 + 12 + 15 + 18 + 18 + 26 + 29 + 30 + 32 + 58 + 61}{14}\)
\(26= \frac{ 2nd + 12th+304}{14}\)
Multiply through by 14
\(14 * 26= 2nd + 12th+304\)
\(364= 2nd + 12th+304\)
This gives:
\(2nd + 12th = 364 - 304\)
\(2nd + 12th = 60\)
From the updated box,
\(\begin{array}{ccccccccccccccc}{1} & {[ \ ]} & {4} & {12} & {15} & {18}& {18 } & {26} & {29} & {30} & {32} & {[ \ ]} & {58} & {61} \\ \end{array}\)
We know that:
The 2nd value can only be either 2 or 3
The 12th value can take any of the range 33 to 57
Of these values, the only possible values of 2nd and 12th that give a sum of 60 are:
\(2nd = 3\)
\(12th = 57\)
i.e.
\(2nd + 12th = 60\)
\(3 + 57 = 60\)
So, the complete box is:
\(\begin{array}{ccccccccccccccc}{1} & {3} & {4} & {12} & {15} & {18}& {18 } & {26} & {29} & {30} & {32} & {57} & {58} & {61} \\ \end{array}\)

one card is drawn from a pack of 52cards each of the 52 cards being equally likely to be drawn. what is the probability that the card drawn is a king?
The probability of drawing a king from a standard deck of 52 cards is 1/13.
In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.
To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).
The total number of possible outcomes is 52 because there are 52 cards in the deck.
The favorable outcomes, in this case, are the four kings.
Therefore, the probability of drawing a king is given by:
Probability = (Number of favorable outcomes) / (Number of possible outcomes)
= 4 / 52
= 1 / 13
Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.
This means that out of every 13 cards drawn, on average, one of them will be a king.
It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.
Each draw is independent, and the probability of drawing a king is constant.
