List in ascending order:-
32 39 45 48 50 57 65 68 70
Q1 = (39+45)/2 = 42
Q2 = 50
Q3 = (65+68)/2 = 66.5
Correct option is the first one.
5.
aritmetic is same increase per term
14 to 21 is 7
21 to 42 is 21
7≠21
no
6.
decreases by 4 each time
an=a1+d(n-1)
an=10-4(n-1)
n=12 for 12th term
a12=10-4(12-1)
a12=10-4(11)
a12=10-44
a12=-34
it is -34
7.
missing term is y
22+n=y
y+n=34
22+n+n=34
22+2n=34
minus 22 from both sides
2n=12
divide both sides by 2
n=6
22+n=y
22+6=y
28=y
28 is answer
5. no
6. -34
7. 28
Answer: 18.52
Step-by-step explanation: not exactly sure if this is right. Had to look it up sorry. (Link=https://www.mathwarehouse.com/arithmetic/square-root-calculator.php)
343−−−√49⋅7−−−−√ 49−−√7–√ 77–√
343−−−√≈18.520259177452136
140
25+105+90=220
360-220=140
Y=-1/2x+3 is the slope intercept form.
