Answer: I disagree with Penny's statement. The probability of her selecting a green pair of swim goggles and then a green sand bucket is the product of their individual probabilities. The fact that she selected a green pair of swim goggles does not change the probability of selecting a green sand bucket. Each selection is independent of the other, and the probabilities of each event remain the same. So, Penny's statement that "because she selected a green pair of swim goggles, she was more likely to select a green sand bucket" is not valid.

Answer:
Values of x are ±4 and ±5
Step-by-step explanation:
Let y = [tex]x^{2}[/tex]
Which means: [tex]y^{2} = x^{4}[/tex]
Therefore:
A quadratic equation is formed:
[tex]y^{2} - 41y + 400 = 0[/tex]
The above quadratic equation can be simplified either by The Double Bubble Method or using the quadratic formula
Double Bubble Method:
[tex]y^{2} - 41y + 400 = 0[/tex]
The pair of factors of 400 that add together to give 41 are 25 and 16. Use these two factors to rewritre -41y:
[tex]y^{2} - 25y - 16y + 400 = 0[/tex]
Then do Factorization by grouping (i.e group the terms with common factors before factorizing):
[tex]y(y -25) - 16(y - 25) = 0[/tex]
[tex](y - 25)(y - 16) = 0[/tex]
The product of two expressions is zero, which means either of the two expressions is equal to Zero:
Either: [tex]y - 25 = 0[/tex]
Substituting [tex]y = x^{2}[/tex]:
= [tex]x^{2} - 25 = 0[/tex]
= [tex]x^{2} = 25[/tex]
= [tex]\sqrt{x^{2}} = \sqrt{25}[/tex]
∴ x = ±5
Or: [tex]y - 16 = 0[/tex]
Substituting [tex]y = x^{2}[/tex]
[tex]= x^{2} - 16 = 0[/tex]
[tex]= x^{2} = 16[/tex]
[tex]= \sqrt{x^{2}} = \sqrt{16}[/tex]
∴ x = ±4
∴Values of x are ±4 and ±5

The box-and-whisker plot below represents some data set. What percentage of the data values are greater than 72?
Answer:
In a box-and-whisker plot, the box represents the middle 50% of the data, with the median value marked by a vertical line inside the box. The "whiskers" extend from the box to the minimum and maximum values in the data set that are not considered outliers. Outliers are marked by individual points outside the whiskers.
To determine the percentage of data values that are greater than a given value, we need to look at the box-and-whisker plot to see where that value falls in the data set. If the value is outside the box, we know that at least 50% of the data values are either greater or less than that value, depending on whether the value is greater or less than the median. If the value is inside the box, we know that exactly 50% of the data values are greater and 50% are less than that value.
In the case of the value 72, we cannot determine the percentage of data values that are greater than it without knowing where it falls in the box-and-whisker plot. If it falls outside the box, we only know that at least 50% of the data values are greater than it. If it falls inside the box, we only know that exactly 50% of the data values are greater than it.

Elish was required to write a 600 word Literature essay. After working away for one hour, the word count on her computer showed that she had typed 240 words. What fraction of the essay does Elish still need to complete? Write your answer in simplest form
If Elish was required to write a 600 word Literature essay and word count on her computer showed that she had typed 240 words Elish still needs to complete 3/5 of the essay.
To find the fraction of the essay that Elish still needs to complete, we need to determine how many words she has left to write. We can do this by subtracting the number of words she has already written from the total required word count:
Words left to write = Total word count - Words already written
Words left to write = 600 - 240
Words left to write = 360
Now, to find the fraction of the essay that Elish still needs to complete, we can express the remaining words as a fraction of the total word count:
Fraction of essay left to complete = Words left to write / Total word count
Fraction of essay left to complete = 360 / 600
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 120:
Fraction of essay left to complete = (360 ÷ 120) / (600 ÷ 120)
Fraction of essay left to complete = 3 / 5
This means that she has completed 2/5 of the essay so far (which is the equivalent fraction of 240/600).

x = 3 4/3 and y = 13 1/3.How to find the numbersLet's call the numbers x and y
From the first equation, we have:
2x + y = 18
From the second equation, we have:
3x - y = 7
Solving simultaneously by substitution method
3x - y = 7
3x = 7 + y
x = (7 + y)/3
substitute this expression for x into the first equation:
2x + y = 18
2((7 + y)/3) + y = 18
14/3 + 3y/3 = 18
14/3 = 18 - 3y/3
14/3 = 18 - y
collecting like terms
y = 18 - 14/3
y = 18 - 4 2/3
y = 13 1/3

At the concrete level, I would introduce the concept of more than/less than with a hands-on activity. For example, I would have students compare the number of counters or blocks and have them determine which group has more or less. This would help them develop a fundamental understanding of the concept.At the semi-concrete level, I would introduce the concept of more than/less than with written numerals. I would have students compare numbers on paper, such as 4 and 6, and have them determine which number is more or less. I would also ask them to use concrete objects to represent the numbers, such as using four counters for 4 and six counters for 6.At the abstract level, I would introduce the concept of more than/less than with larger numbers. I would ask students to compare numbers such as 12 and 15, and determine which number is more or less. I would also ask them to use abstract symbols, such as 12 + and 15 -, to represent the numbers.By using this step-by-step approach, students will be able to move from the concrete level to the semi-concrete and finally to the abstract level of understanding the more than/less than concept. This will help them develop a strong foundation of the concept, which will allow them to solve more complex problems in the future.
