Answer:
(a)4
Step-by-step explanation:
First you would distribute the 2 within the parentheses and it becomes 14n-46 <= 14-16n. Then you would find the smallest coeficent and do the inverse operation so you would have to add 16n to 14n and get 30n. Your equation is now 30n-46<=14. Now you want to isolate the variable by doing the inverse operation of -46. You would then add 46 to positive 14 and get 60. Your eqaution now is 30n<=60. Your last step is to divide 30 on each side which leaves you with n<=2.
2 is less than or equal to 2
-2 is less than or equal to 2
-4 is less than or equal to 2
4 is NOT less than or equal to 2 it is GREATER
Hopefully, that helps.
Answer:
Step-by-step explanation:
Given that a statistics teacher taught a large introductory statistics class, with 500 students having enrolled over many years.
Mean = 78 and std dev =10
Next time, sample size n was reduced to 25
For smaller sample size the mean was found to be = 83
The teacher wanted to know if teaching a smaller class was more effective and students performed better
ie comparison of two means of two samples should be done with different sample sizes but same teacher.
Hence hypothesis should be:
where x denotes the I sample and Y the second with 25 students.
If Nick began with three clients, you would do basic math to get here.
January / 3
February / 3•2 = 6
March / 6•2 = 12
April / 12•2 = 24
May / 24•2 = 48
June / 48•2 = 96
July / 96•2 = 192
August / 192•2 = 384
September / 384•2 = 768
October / 768•2 = 1,536
November / 1,536•2 = 3,072
December / 3,072•2 = 6,144
Nick would start with 3 clients and end with 6,144 clients.
Answer:
7 < x
Step-by-step explanation:
-3< x-10
-3+10 < x -10+10
7< ×
