Answer:
f(-2) = 3
Step-by-step explanation:
Given that,
f(x) = x + x + 7
We need to find the value of f(-2).
Put x = -2 in the given function.
f(-2) = (-2) + (-2) + 7
= -2-2+7
= -4+7
= 3
Hence, the value of f(-2) is equal to 3.
Answer:
steps below
Step-by-step explanation:
1. The series contains a combination of two arithmetic sequence series. The number series in the odd position (100,90,80,..) is an arithmetic series with a common difference of 10, and the even number group (3,10,15,...) is another arithmetic series with a common difference of 5.
2. sequence 1 (Odd): a₁ = 100 d = 10 next term is 60
sequence 2 (Even): a₁ = 5 d = 5 next term is 20
3. next 2 terms of the series are 60, 20
The correct answer is A. The 200 randomly selected students
Explanation:
In most studies, the complete population is not surveyed or studied instead, a specific number of individuals are selected, this group is known as the sample. Additionally, the sample represents the population, and due to this, their answers are used to make inferences about all the population.
According to this, the population is all the students in the school, while the sample is the 200 randomly selected students because this is the group that is going to be studied to make conclusions and inferences about all the population.
Answer:
Step-by-step explanation:
4(5-2)+(-7)(0.5)
20-8+(-3.5)

8.5
Answer:
25
Step-by-step explanation:
First you have to figure out how much each is worth by itself.
carmel =30
coco chips =50
coconut= 45
then add all of them you'd get 125
subtract 125 from 150 and get 25
