So on solving the provided question we can say  that factors 8 = 1,2,4,8 factor 20 = 1,2,4,5,10,20

Any natural number other than 1 with just itself and the number 1 as its divisors is considered a prime factor. Actually, 2, 3, 5, 7, 11, and so on are some of the first prime numbers. an amount that has been multiplied to produce another amount. By dividing 15 by 3 and 5, for instance, we get 3 5 = 15. main elements: Prime factors include all factors that are prime but are not composite. A few prime factors of 30 are 2, 3, and 5. Only 2 and 3 are prime factors of 12, so listing 2 twice as 2 2 3 (or 22 3) is necessary to factorize 12. The sum of 2 + 3 is not 12.

The constant of proportionality of the graph is 12.

Proportional relationships are relationships between two variables where their ratios are equivalent. In other words, a proportional relationship is one in which two quantities vary directly with each other.

Proportional relationship can be represented mathematically as follows:

y = kx

where

Therefore, let's use (3, 36) to find the constant of proportionality.

Hence,

y = kx

36 = 3k

divide both sides by 3

3k / 3 = 36 / 3

k = 12

In mathematics, a percentage (from Latin: per centum, "by a hundred") is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%",although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number (pure number); it has no unit of measurement.

The term "percent" is derived from the Latin per centum, meaning "hundred" or "by the hundred". The sign for "percent" evolved by gradual contraction of the Italian term per cento, meaning "for a hundred". The "per" was often abbreviated as "p."—eventually disappeared entirely. The "cento" was contracted to two circles separated by a horizontal line, from which the modern "%" symbol is derived.

A linear model can be represented by the equation y = mx + b, where y is the dependent variable (megawatt hours generated by hydropower), x is the independent variable (years since 2007), m is the slope of the line, and b is the y-intercept.

To find the slope (m) and y-intercept (b) for this problem, we can use the two points given: (2007, 248) and (2012, 277).

m = (277 - 248) / (2012 - 2007) = 29 / 5 = 5.8

b = 248 - (5.8)(2007) = 248 - 11456 = -11208

So the linear model representing the number of megawatt hours generated by hydropower as a function of the number of years since 2007 is:

y = 5.8x - 11208

where x is the number of years since 2007.

ax² + bx + c = 0

where x is the unknown variable and a, b and c are the constant terms.

The given equation is :

40x² = 30

40x² - 30 =0

Common factor:

10(4x²- 3) = 0

4x²- 3 = 0

a = 4

b = 0

c = -3

x =  -0±[tex]\sqrt{0^2-4(4)(-3)}[/tex]/ 2(4)

C. Expression 2. Sarah can’t combine -4 and -6. She must combine -4 with 8.

D. Expression 3. Sarah applied the Distributive Property but incorrectly multiplied 1/2 (-6).

Expressions 1, and 2 are equivalent because they are using the distributive property to expand the term within the brackets before applying the 1/2 coefficient.

Expression 3 is not equivalent because it does not use the distributive property and does not have the same terms as the other expressions.

The interquartile range (IQR) of this dataset is 8.25, it means that half of the observations fall between 53 and 61.25, while half of the observations fall outside of that range.

IQR stands for Interquartile Range, which is a measure of the variability of a dataset. It is defined as the difference between the third quartile (Q3) and the first quartile (Q1). To calculate the IQR, you first need to order the data set and find the median (middle value) of the dataset, and the Q1 and Q3.

Here is the dataset you provided, in order:

53 53 53 54 55 56 59 60 61 62 63 88

The median of the dataset is: (56+59)/2 = 57.5

Q1 is the median of the lower half of the dataset: (53+53+54)/3 = 53

Q3 is the median of the upper half of the dataset: (60+61+62+63)/4 = 61.25

Now you can calculate the IQR:

IQR = Q3 - Q1 = 61.25 - 53 = 8.25

So the interquartile range of this dataset is 8.25, it means that half of the observations fall between 53 and 61.25, while half of the observations fall outside of that range.
