Answer:
Hi, There! FrozenVines Here!
I'm here to help you Understand Better So Let's go-
20:24 is My Answer
Step-by-step explanation:
y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio
proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.
For example 2/5 is Equal to 4/10 this Would be A Example Of a Proportional relationship!
Answer:
Correct option: A. Weight.
Step-by-step explanation:
In regression analysis there are two kinds of variables: Explanatory and Response variable.
The explanatory variable are used to predict the changes in the response variable. They are also known as independent or predictor variable.
The response variable are observed for any changes caused by the explanatory variable. They are also known as the dependent or experimental variable.
In this case it is provided that heavier cars have lower fuel efficiencies.
It implies that there is linear inverse relationship between the variables weight of the car and fuel efficiency.
The response variable is the fuel efficiency and the explanatory variable is the weight of the car. Since the weight of the car is used to determine the fuel efficiency.
Thus, the explanatory variable is the weight of the car.
The answer will be 138.16
You will find the answer by multiplying by 2 and 22 which will give you 44, then you multiply that but 3.14 which will give you 138.16
Answer:
0.267 or 26.7%
Step-by-step explanation:
The probability of an event happening is calculated by dividing the favorable outcomes by all outcomes:
The sum of all events (marbles) is 6 + 15 + 8 + 1 = 30
The number of favorable events is 8
Therefore, the probability is 8/30 ≈ 0.267 or 26.7%
