5y+30+2y<4y+8
5y+2y-4y<8-30
3y<-22
y<-22/3
Answer:
25-2
---------- less than 8
3
Step-by-step explanation:
25 - 2 = 23
23/3 = 7.666...
the answer to the inequality will be less than 8 since 7.6666... < 8

To find the critical value
that corresponds<span> to 97% confidence level</span>:
Step 1:
Subtract 0.97 from 1:
1 - 0.97 = 0.03
Step 2:
Divide 0.03 by 2:
0.03 / 2 = 0.015
Step 3:
Subtract 0.03 from 1:
1 - 0.015 = 0.985
Step 4:
From the normal distribution table, the z score that corresponds to a probability of 0.985 is 2.17.
Therefore, <span>the critical value that corresponds to 97% confidence level is 2.17.</span>
