Answer:
The margin of error for a sample size of 250 is 6
Step-by-step explanation:
The margin of error is given as
1/square root of the sample size
Thus, margin of error for a sapless size of 250 is
1/√250
= 1/15. 811
= 6
You have to post a picture of the actually histogram we can’t see it
Answer:
its 3 inches
Step-by-step explanation:
Because 9 divided by 3 is 3 (in.) as well as 6 divided by 2 and if its equilateral, all sides are the same (i hope this makes sense)
75+ 15x ≥ 140
⇒ 15x ≥ 140-75
⇒ 15x ≥ 65
⇒ x ≥ 65/15
⇒ x ≥ 13/3
⇒ x ≥ 4 1/3
Final answer: x ≥ 4 1/3~
