Solve using the elimination method x + 5y = 26 - X+ 7y = 22

S_A_V [24]

Answer:

$x=6\\y=4$

Step-by-step explanation:

Elimination method:

$x+5y=26$

$-x+7y=22$

Add these equations to eliminate x:

$12y=48$

Then solve $12y=48$ for y:

$12y=48$

$y=48/12$

$y=4$

Write down an original equation:

$x+5y=26$

Substitute 4 for y in $x+5y=26$ :

$x+5(4)=26$

$x+20=26$

$x=26-20$

$x=6$

{ $x=6$ and $y=4$ } ⇒ $(6,4)$

hope this helps...

Find the median, range, and interquartile range of both sets:

Sever21 [200]

Answer:

C) Both sets have an interquartile range of 27.

Step-by-step explanation:

Sorted data

Set 1: 65, 66, 77, 79, 81, 93, 104, 105

Set 2: 1, 29, 56, 59, 60, 67, 72, 74

Median position: (8+1)/2 = 4.5th value

Ranges:

Set 1: 105 - 65 = 40

Set 2: 74 - 1 = 73

Medians:

Set 1: (79+81)/2 = 80

Set 2: (59+60)/2 = 59.5

IQR:

Set 1: (93+104)/2 - (66+77)/2

= 27

Set 2: (67+72)/2 - (29+56)/2

= 27
