289 196 248 379 319 276 198 349
(in order) 196, 198, 248, 276, 289, 319, 349, 379 there are eight numbers.
--------------------------------------------------------------------------------------
196, 198, 248, 276
since the median is between 198 and 248, we must add both numbers together and divide them by two:
(198 + 248) ÷ 2
= 446/2
<h2>
= 223 (first quartile)</h2>
--------------------------------------------------------------------------------------
289, 319, 349, 379
since the median is between 319 and 349, we must add both numbers together and divide them by two:
(319 + 349) ÷ 2
= 668/2
<h2>
= 334 (third quartile)</h2>
--------------------------------------------------------------------------------------
Interquartile range:
<h2>
IQR: 334 - 223 = 111 </h2>
<em>I double-checked my answers btw</em>
Solve for Y
6x+12y=3
-6x+10y=-14
22y/22=-11/22
y=-1/2
Now solve for X
6x+12(1/2)=3
6x+6=3
6x/6=-3/6
x=-1/2
I hope it's the correct answer. Good Luck!
Answer:
m = 1/3
b = -6
Step-by-step explanation:
How to calculate slide (m):
x1 = 0
x2 = -12
y1 = -6
y2 = -10
If we put in the values:
Subtracting a negative number is the same as adding it:
-6 + 10 = 4 and 0 + 12 = 12 so now we have this:
Lets simplify:
4 and 12 can both be divided by 3:
3 and 1 are prime numbers and cannot be simplified further.
Now we know that m=1/3
Since:
y = mx + b
y = -6
x = 0
m = 1/3
Then:
-6 = 1/3*0 + b
1/3*0 is 0, so we can just remove that part:
-6 = b
that means b is equal to -6
