It’s a function. So for every X-input, there is a Y-output. Or in this case, P-input and C-output. When you plug in 1 for P in the equation, you get the answer for c which is 115. Continue plugging in the number of painting sold for the P and you get your output of c! Use the chart given. Hope this helps
Answer:
Well to start with, a coefficient is a number that is placed before a variable. In this case we have 10x+8, so the coefficient is well 10.
Step-by-step explanation:
The correct answer is B. Stratified sampling is used since the field is divided into subplots and a random sample is taken from each subplot.
Explanation:
Sampling refers to the process followed by researchers to select a group of individuals from a larger group; considering in most studies it is not possible to analyze all the population. In the case of stratified sampling, this involves dividing the general population into smaller groups, which are known as strata; after this, the researcher selects a specific number of individuals from each strata. This method guarantees the sample is selected randomly, and therefore the study is not biased. Stratified sampling was the method used in the example described because, in this, the general population (46-acre field) was divided into subplots that represent the strata. Also, after this, the researcher selected one random sample.
Answer:
1/3
Step-by-step explanation:
(-5,4)=(x1,y1)
(1,6)=(x2,y2)
Slope(m)=y2-y1
_____
x2-x1
=6-4
____
1+5
=2÷6
=1/3
Answer:
x = ±sqrt(y-11)
Step-by-step explanation:
y = x^2 +11
Subtract 11 from each side
y -11 = x^2 +11-11
y-11 = x^2
Take the square root of each side
±sqrt(y-11) = sqrt(x^2)
±sqrt(y-11) = x
