Answer:
A = strong negative correlation
B = positive correlation
C = very weak or no correlation
Step-by-step explanation:
Scatter plot A:
A clear linear trend line could be observed having a negative slope ; the nature of the slope gives the nature of the correlation (positive or negative). Since the slope is negative then we have a negative correlation. The linear trend line is almost straight with only few points marginally missing the best fit line. Hence. We can conclude to have a strong negative correlation.
Scatter plot B :
Has a positive slope, and hence a positive correlation. The best fit line miss a few points but the linear trend of the plot is still observable. Hence, we can conclude to having a fairly strong positive correlation.
Scatter plot C :
From the graph, no linear trend can be observed and hence it is fit to say that no correlation exists between the points.
Let's restate your first sentence: the length of AB is 15 cm.
For dilation, we would have to multiply 15 by 0.4 and that would lead us to our answer: 6 cm. Hope this helps!
We have to express the number 304,800,400 in standard and expanded form.
The expanded form is shown as a sum of each digit multiplied by its matching place value. Let us express the number in expanded from.
So, 304,800,400 = 
= 
So, this is the expanded form of the given number.
Standard form is a way of writing down very large or very small numbers easily.
The standard from of the number is:
304,800,400 = 
.
