Hey there! :)
Answer:
h(x) = 3x² - 7x - 6
Step-by-step explanation:
Calculate h(x) by adding the two polynomials:
h(x) = f(x) + g(x):
h(x) = x² - 3x + 5 + 2x² - 4x - 11
Combine like terms:
h(x) = 3x² - 7x - 6
Answer:
0
Step-by-step explanation:
0 divided by anything is always 0, so you don't have to round.
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.
Answer:
A point labeled R is placed in between the 7th and 8th tick marks to the left of 0. A point labeled T is placed on the 1st tick mark to the right of 0
Step-by-step explanation:
negative 7 1/2 is between negative 7 and negative 8
+1 is 1 to the right of 0
