Your answer is 26.
We have to go at this kind of backward.
We find the average by adding up the numbers, then dividing by how many numbers we have.
In this example, we will have 5 numbers...so
x divided by 5 = 18
x/5 = 18
x = 90
The sum of all 5 numbers is 90, so then subtract the 4 numbers you already know to find the one you’re missing. (We’ll call it n)
90 - 8 - 12 - 18 - 26 = n
90 - 64 = n
n = 26
Please let me know if you have any questions.
The answer is A , for determining range look at Y-axis only from down to up .For this question we can also say
range: [1,7] , if both ends of the line are arrows it means the line goes from negative infinity to positive infinity (which means range is all real numbers) , but if the point is include just like this graph the points will be also include in range , but if the points are an empty circle the points won't be include for writing range
hope it helps
please give brainliest
-4x-2y=-12
4x+8y=-24
--------------------------add
6y = -36
y = -6
Substitute y = -6 into -4x-2y=-12
-4x-2(-6) = -12
-4x + 12 = -12
-4x = -24
x = 6
Answer
x = 6 and y = -6
Answer:
Population = All registered voters in Raleigh city
Population size = 9500
Sample size = 360
Proportion of sample statistic for brown = 0.3167
3008 voters
Step-by-step explanation:
Population refers to all elements which meets the requirement for a specific experiment or research interest.
Number of voters for brown = 114
Number of voters for Feliz = 210
Undecided = 36
Sample statistic for proportion in support of brown :
Proportion = x / n
x = number who said they'll vote for brown
n = sample size
Sample statistic for proportion in support of brown = 114 / 360 = 0.3167
Using the proportion ; number from population who'll vote brown :
Sample proportion * population size
0.3167 * 9500 = 3008 voters
