Answer:
(0, -2) and (1, 1) both work in this system of equations.
Step-by-step explanation:
Happy to help! The best way to find if it is a solution is to look for those points on the graph. When we graph the point, it needs to fall in an area where both lines or shaded or on a solid line.
Look carefully and see if you can find points like these!
(0, -2) falls on a solid line.
(1, 1) falls in the double shaded area.
Therefore, (0, -2) and (1, 1) both work in this system of equations.
Good luck!

What is the mean of the sampling distribution of the means?
The sampling distribution of the means has a mean of 172 pounds and a standard deviation of 4.83 pounds.
In the context of sampling distribution of the means, the standard deviation represents the degree of spread or variation of sample means around the true population mean.
To compute the standard deviation of the sampling distribution of the means, one typically divides the population standard deviation by the square root of the sample size.
Therefore, the standard deviation of the sampling distribution of the means is 29/√36 = 29/6 = 4.83 pounds.
So, the sampling distribution of the means has a mean of 172 pounds and a standard deviation of 4.83 pounds.

To find the number of females in the class, we can start by calculating the number of males.
Given that 30% of the class are males, we can calculate it as follows:
Number of males = 30% of total number of people
= 30% of 30
= (30/100) * 30
= 9
Since we know that the total number of people in the class is 30, we can find the number of females by subtracting the number of males from the total:
Number of females = Total number of people - Number of males
= 30 - 9
= 21
Therefore, there are 21 females in the class.
Answer:
m = 3
Step-by-step explanation:
5m - 12 = m
subtract 5m from both sides
5m - 5m - 12 = m - 5m
simplify
-12 = -4m
divide both sides by -4
-12 / -4 = -4m / 4
simplify
3 = m
hope this helps :)
Please give an explanation to the answer
Answer:
x = 12
Step-by-step explanation:
This equation is very easy to solve.
3x - 13 = 23 Add 13 to both sides of the equation.
3x = 36 Divide by 3 on both sides of the equation.
x = 12
Then, check your answer by substituting the solved value.
3(12) - 13 = 23
36 - 13 = 23
23 = 23
Therefore, x = 12 is the solution to the equation.
Answer:
x = 12
Step-by-step explanation:
3x - 13 = 23
Bring non-variable numbers to other side:
3x = 36
Divide both sides by 3:
x = 12
