Descriptive statistics
Explanation:
The population average is a descriptive statistic. It informs about how the population looks like, in this case, the population looks like having a average of 1000.
If, using her class's average where to infer the population average that is inferential statistic. But that is not the case
The answer would be 21... did you type something in the wrong order, or is there suppose to be an exponent? What’s the * for
7x - 14y = -56
Divide the equation by 7,
x - 2y = -8
2y = x + 8
y = 1/2x + 8
In short, Your Answer would be: y= 1/2x + 4
Hope this helps!
Answer:
The fraction of the money that Lisa received will be 5x/13
Step-by-step explanation:
The the amount shared by Lisa and ant be x
If Lisa and ant share the money in the ratio 5:8, to get the fraction Lisa received;
Step1:
The total ratio will give:
5+8 = 13
Since the ratio Lisa got was 5, then the fraction of money Lisa receive will be:
Lisa ratio/Total ratio × Amount shared
= 5/13 × x
= 5x/13
Therefore, the fraction of the money that Lisa received will be 5x/13
Hello from MrBillDoesMath!
Answer: Using the diagram provided the question can not be answered.
Discussion:
The 3 angles of a triangle add up to 180. From the diagram
73 + ( 6x + 4) + ( 8y -7) = 180
This equation has two variables, x and y, and we can't solve it as such. BUT if the third angle was intended to be (8x -7), an assumption totally, then
73 + ( 6x + 4 ) + ( 8x -7) = 180 or
73 + (6x + 8x) + (4 -7) = 180 or
73 + 14x -3 = 180 or
14x + 70 = 180 or
14x = 180 -70 = 110
x = 110/14 = 55/7
Thank you,
MrB
