Answer:
-2
Step-by-step explanation:
-10 = -6 + 2x
-10+6=2x
-4÷2x
-2=x
Step 2 Add 5 negative unit tiles to both sides
Step 3 The solution is x = 1.
Which explains whether Brandon is correct?
Brandon is correct because he has the correct solution in step 3.
Brandon is correct because he forms zero pairs to isolate the variable by using the lowest coefficient each time.
Brandon is not correct because he should have performed step 2 before performing step 1.
Brandon is not correct because he should have added 6 negative unit tiles to isolate the variable in step 2.
The correct option is Option D: Brandon is not correct because he should add -6 on both sides to isolate the variable in step 2.
The linear equation is an equation where the highest degree of the variable used in the equation is 1.
For example 2x+5=25
Given the equation is 15x +6= 14x+ 5
In order to the linear equation first, try to keep the constant and the variable part to one side by adding or subtracting the constant term.
Then divide the coefficient of the variable (if the coefficient is not equal to 1) on both sides.
Here the given equation is 15x +6= 14x+ 5
Step-1: adding -14x on both sides
⇒15x +6 -14x= 14x+ 5 -14x
⇒x+ 6= 5
Step-2: adding -6 on both side
⇒x+ 6-6 = 5-6
Step-3: solution will be -1
⇒x= -1
Therefore the correct option is Option D: Brandon is not correct because he should add -6 on both sides to isolate the variable in step 2.

Answer:
0.8333%
Step-by-step explanation:
Assuming that there is only one possible shortest route, the probability that a randomly selected route is given by one divided by the permutation of the order of five different sites:
There is a 1 in 120 chance, or 0.8333% chance that a randomly selected route is the shortest possible route.

Let X be the total taxable earnings, in millions, of all wage earners in a county. The mean total taxable earnings of all wage earners in a county across all the counties in James' sample is x??.
Use the central limit theorem (CLT) to determine the probability P that the mean taxable wages in James' sample of 56 counties will be less than $33 million. Report your answer to four decimal places.
P(x??<33)=
Use the CLT again to determine the probability that the mean taxable wages in James' sample of 56 counties will be greater than $30 million. Report your answer to four decimal places.
P(x??>30)=
Answer:
1
The probability is
2
The probability is
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
The sample size is
Generally the standard error for the sample mean is mathematically evaluated as
substituting values
Apply central limit theorem[CLT] we have that
substituting values
From the z-table we have that
For the second question
Apply central limit theorem[CLT] we have that
substituting values
From the z-table we have that
Thus
