x = -4y + 9
x - y = 4
Answers
Answer:
please what should we found? is it the value of ×or y
x - y = 4
- rearrange the second equation to x = 4 + y
- then we can plug it into x for the first equation
4 + y = -4y + 9 — then we solve for y
y = -4y + 5
5y = 5 -> y = 1
we can then plug in 1 (our y value) into the original second equation.
x - 1 = 4 -> x = 5
x = 5 & y = 1
you should put it in a coordinate layout so:

Answer:
[tex]Accept = 69.44\%[/tex]
[tex]Reject = 11[/tex]
Step-by-step explanation:
Given
See attachment for dataset
Solving (a): Percentage to accept
The percentage to accept are flea collars that range between 14mg to 16mg (inclusive)
From the attachment, we have:
[tex]Total = 36[/tex]
[tex]n(14mg-16mg) =25[/tex] --- Number of 14mg to 16mg
So, the percentage to accept is:
[tex]Accept = \frac{n(14mg-16mg)}{Total} * 100\%[/tex]
[tex]Accept = \frac{25}{36} * 100\%[/tex]
[tex]Accept = 0.6944 * 100\%[/tex]
[tex]Accept = 69.44\%[/tex]
Solving (b): Collars to reject
In (a), we have:
[tex]n(14mg-16mg) =25[/tex]
The number to reject is then calculated by subtracting the collars to accept from the total (this is called complement rule)
So, we have:
[tex]Reject = Total - n(14mg - 16mg)[/tex]
[tex]Reject = 36 - 25[/tex]
[tex]Reject = 11[/tex]
11 will be rejected

the one angle is 135 degrees and to find the other one we can just subtract 360 - 135
the other angle is 225°
we can set it up as:
12 yd x
——— = ——-
225 135
to find x, cross multiply 135 and 12 which gives you 1,620
1,620 / 225 = 7.2
the other angle is 7.2 yards!
