Answer:
12:176 or 12/176
Step-by-step explanation:
Multiply both the top and bottom by 2.
6/88. 6 x 2= 12. 88 x 2= 176
So, 6:88 = 12:176 because you multiplied both numbers by 2.
6/88 x 2/2 = 12/176
Answer:
(262, 690)
Step-by-step explanation:
Given that :
Mean score = 476
Standard deviation, s = 107
2 standard deviations above and below the mean :
Mean ± 2s
Hence,
2 standard deviations below :
476 - 2(107)
476 - 214 = 262
2 standard deviations above
476 + 2(107)
476 + 214 = 690
Plug 4 in to the function
f(4)=4(4)+7
f(4)=16+7
f(4)=23
Final answer: 23
