13
step-by-step explanation:
169-1=168
168-3=165
165-5=160
160-7=153
153-9=144
144-11=133
133-13=120
120-15=105
105-17=88
88-19=69
69-21=48
48-23=25
25-25=0
since it took 13times to completely subtract it hence its square root is 13
the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.
spinner 1 spinner 2
1 1
1 2
1 3
1 4
2 1
2 2
2 3
2 4 = not 1, and 4
3 1
3 2
3 3
3 4 = not 1, and 4
only 2 outcomes have passed the given condition.
