PLEASE HELP ME!! Tristen solved the equation log 3(x+1) - log 3(x-6) = log 3(2x + 2). Justify each step of solving the equation in Tristen's work below. Are both numbers solutions to the equation? Explain.
Justify each step of solving the equation in Tristen's work.
log 3(x+1) - log 3(x - 6) = log 3(2x+2)
Write the original equation
log 3(x + 1) = log 3(x-6) + log 3(2x + 2) Subtract the same logarithm from each side.
log 3(x + 1) = log 3(x-6)(2x + 2)
Power Property of Logarithms
(x + 1) = (x - 5)(2x+2)
Property of Equality for Exponential Equations
x + 1 = 2x2 - 10x - 12
Divide.
0 = 2x2 - 11x - 13
Subtract x + 1 from each side.
x=6.5 or x = -1
Apply the Zero Product Property.
Are both numbers solutions to the equation? Explain. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. Only the one solution x = is correct, and it is extraneous
OB. Both solutions are correct, and the solution(s)= is/are extraneous
(Use a comma to separate answers as needed.)
O C. Both solutions are correct, and neither solution is extraneous

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.

The average daily maximum temperature for laura’s hometown can be modeled by the function f(x)=4.5sin(πx/6)+11.8 , where f(x) is the temperature in °c and x is the month. x = 0 corresponds to january.what is the average daily maximum temperature in may? round to the nearest tenth of a degree if needed.use 3.14 for π .
