Match each equation on the left of the equivalent equation on the right some answer options on the right will not be used
(left) log_2(0.25) = -2 , 5^2 =25 , log_2(32) = 5 , 25^-1 = 0.04 (right) 2^5 = 32 , 0.25^2 = -2, log_25 (0.04) =-1 , log_0.04(-1)=25, 2^-2 = 0.25, log_5(25) =2
The equations log₂ (0.25) = -2, 5² = 25, log₂ 32 = 5 and 25⁻¹ = 0.04 are equivalent to the equations 2⁻² = 0.25, log₅ 25 = 2, 2⁵ = 32, log₂₅ 0.04 = -1 respectively.
What are Logarithms?Logarithms are another way, which is the opposite of writing exponents. A number raised to some power will give some other values in case of exponentiation process. This power is called the logarithmic value.
We can write it as,
logₐ x = n ⇔ aⁿ = x
We have the equations on the left equivalent to the equations on the right using the definition of logarithms as,
log₂ (0.25) = -2 ⇔ 2⁻² = 0.25
5² = 25 ⇔ log₅ 25 = 2
log₂ 32 = 5 ⇔ 2⁵ = 32
25⁻¹ = 0.04 ⇔ log₂₅ 0.04 = -1
Hence the equations on the lefts log₂ (0.25) = -2, 5² = 25, log₂ 32 = 5 and 25⁻¹ = 0.04 are equivalent to the equations on the rights 2⁻² = 0.25, log₅ 25 = 2, 2⁵ = 32, log₂₅ 0.04 = -1 respectively.

The coefficient of determination if the total sum of squares is 23.29 and the sum of squares due to regression is 10.03 is 0.43
How to calculate regression?
The standard formula for simple linear regression is Y = mX + b, where Y is the response (dependent) variable, X is the predictor (independent) variable, m is the estimated slope, and b is the estimated intercept.
Here we need to find the coefficient determination if the total sum of squares (sst) is 23.29 and the sum of squares due to regression (ssr) is 10.03.
Here we know that the value of the following are given,
Sum of square = 23.29
Sum of regression = 10.03

explain how regression toward the mean can describe two friends who have a fight then later go to the movies together.
Given the circumstances of the question, it is feasible that the two friends would feel that they overreacted during the argument, and as a result, they decide to see a movie together to make up for it.
Regression toward the mean is a statistical condition that involves events that the outcomes produce based solely on chance rather than on real facts. Therefore, it is impossible to forecast with precision what will happen in a regression towards the mean.
Example
Two military units are brought back, one with 20% casualties and the other with 50%. He compliments the first while criticizing the second. The two units return with the opposite outcomes the following time. He "learns" from this experience that praise reduces performance and berating strengthens it.

the distribution of time spent brushing teeth for the 1,200 students in a school is multimodal with a mean of 43 seconds and a standard deviation of 8.99 seconds. if a random sample of 9 students is selected, is it appropriate to calculate the probability of the sample mean being less than 30 seconds using an approximately normal model?
No, it is not appropriate to estimate the probability using an approximately normal model because the population is not normal and the sample size is small.
The details given are,
Sample size = 9
mean = 43 sec
Standard deviation = 8.99
Therefore we conclude that is it not appropriate to calculate the likelihood of the sample mean being less than 30 seconds using an approximately normal model.

The first and the second terms of the recursive sequence are given as follows:
a) u(1) = -25.
b) u(2) = -15623.
How to solve the recursive sequence?The definition of the recursive sequence is presented as follows:
u(n + 1) = u(n)³ + 2.
The initial term is needed to solve the sequence, hence it is given as follows:
u(0) = -3.
Thus the term with index 1 is given as follows:
u(1) = u(0)³ + 2.
u(1) = -3³ + 2
u(1) = -27 + 2
u(1) = -25.
Considering the term with index 1, the term with index 2 is obtained as follows:
u(2) = u(1)³ + 2
u(2) = (-25)³ + 2
u(2) = -15623.
And then the same rule is obtained if needed to obtain the 3th, 4th terms, and so on, considering the previous term and the definition.

What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that the Xochitl is going to a carnival that has games and rides
The cost of each game is $2.50 and cost of each ride is $5.
Xochitl spent $30 altogether on 9 games
Let x represents the number of games and y represents the number of rides.

d.Two of the above are correct.
e.We can not draw conclusions based on the above statistical output because the conditions are not met due to the extreme out
The conditions are not met by the extreme outliers, hence we are unable to draw inferences based on the statistical output presented above. So, option e is correct.
What is meant by null hypothesis?
The null hypothesis, often known as H₀, is the assertion that there is no difference between two sets of data or variables under analysis, or that there is no relationship between them. Because there is no underlying causative relationship, the null hypothesis holds that any experimentally detected difference is merely the result of chance; therefore, the name "null."
We can create a z-test hypothesis by assuming that the amount of rain produced by thunderheads follows a distribution that is nearly normal:
300 acre feet is the null hypothesis for the average quantity of rain that thunderheads produce on their own without fertilizing the clouds.
Alternative Hypothesis: The amount of rain that thunderheads often produce by seeding the clouds is greater than 300 acre feet.
This test has a right tail.

How does the concept of fractions apply in real life?
In real life, the concept of a fraction is often used when we want to talk about a part of a whole, a part of something, a part of a group of people, etc.
In this case, it is stated that Mrs. Stewart made several pies, some of which were sold and given to food banks, and some were left over.
If we know that 1/4 of the unsold pies were given to the food bank, then the unsold pies that were not given to the food bank = 1 - 1/4 = 3/4 part.
Additionally, we also know that the number of unsold pies that were not given to the food bank (leftover pies) was 150.
If x is the number of unsold cakes, then the two statements above can be written in mathematical notation:
3/4 x = 150
x = 150 : 3/4
= 150 x 4/3
= 200 pies
If pies made are y, then pies not sold = pies made - pies sold
x = y - 3/5y
= 2/5y
if we put the value of x into this equation it becomes:
200 = 2/5y
y = 200 : 2/5
= 200 x 5/2
= 500 pies
Then the pies were sold = 3/5y

The ale tax i 12%.
What i the total price Michael pay for the baket of mangoe?
Total price paid by Michael for the basket of mangoes is $4.48.
For the calculation of total price, price of sales tax will be added with selling price. Forming the equation -
Total price = 4 + 12%×4
Calculating the percentage of sales tax on Right Hand Side of the equation
Total price = 4 + 12×4/100
Solving the percentage part on Right Hand Side of the equation
Total price = 4 + 0.48
Performing addition on Right Hand Side of the equation
Total price = $4.48
