Answer:
option 3
Step-by-step explanation:
Answer: 75% of the rate lies in 47 per month and 55 per month.
Step-by-step explanation:
The mean rate for a satellite television from a sample of households was $51.00 per month, with a standard deviation of $2.00 per month.
According to the Chebychev's Theorem, atleast % of the data lies within k standard deviation from the mean.
For k=2
Alteast 75% of data lies within 2 standard deviation from mean.
i.e. 51-2(2) per month and 51+2(2) per month
i.e. 47 per month and 55 per month
Hence, 75% of the rate lies in 47 per month and 55 per month.
Ohio = 45,000, Cali = 160000, Texas = 270000, Connecticut = 5500, SC = 32000,
A would be true
B would be false
C would be false
D would be true, assuming "about" means you can round up a little.
hope this helped
Difference = -
- 7 - (+ 8) = - 7 - 8 = -15
The correct answer is 3 terms
9c, 2d, and 8 are all single terms because they can’t be combined with anything else in the expression
Hope this helps ;)
