A (-9.5, -9.5) B (5.5,-2.5) C (3.5,3.5)
Answer:
D. 1.2
Step-by-step explanation:
The sum of an arithmetic sequence is the product of the average term value and the number of terms.
The average term is often computed by averaging the first and last terms of the sequence. It can also be computed by averaging the middle two terms of the sequence (when there are an even number of terms, as here).
We are given a_13 is 1.9. We know that a_12 is 3.7 less, so is -1.8. Then the average of these two middle terms is ...
... (-1.8 + 1.9)/2 = 0.05
The product of this value and the number of terms (24) is ...
... 24·0.05 = 1.2 . . . . . the sum of 24 terms of the sequence
absolute value is 8 because the absolute value of a negative is positive and the absolute value of positive stays positive
Answer: F. Parameter, because the data set of all 2000 students in a high school is a population.
Step-by-step explanation:
Parameters is a variable or measure that is calculated from the entire population of data while a statistic is done from a sample of the data.
The question notes that the poll was done on <u>all 2,000</u> students in a high school. This means that the poll is a Parameter because it was done on the entire population of the high school.
Answer:
x = 2
Step-by-step explanation:
x/5 + 1 = 11
x/5 = 10
x = 50
