Answer:
D.
The points do not follow the line of fit, and the line is increasing.
Step-by-step explanation:
Given that correlation coefficient between two variables x and y is 0.30
This implies that there is a positive relationship in other words, when x increases y increases.
Since r is close to 0 than to 1, there is a weak correlation only.
So all points will not lie very close to the line.
There will be positive slope and hence line would be increasing.
Out of the four options correct option would be that which says all points do not follow line of fit and line increases
So option d is right
D.
The points do not follow the line of fit, and the line is increasing.
The triangle tells us that 8x - 4 is equal to 4x + 16 we set them equal to eachother 8x - 4 = 4x + 16 and solve for x
8x - 4x - 4 = 16
4x + 4 - 4 = 16 + 4
4x = 20
x = 5
Then you plug the x value in for x on all 3 of the problems.
8(5) - 4 = 36
4(5) + 16 = 36
5(5) + 7 = 32
Therefore, the correct answer should be B
Answer:
Proportion states that the two ratios or fractions are equal
Given the statement:
The scale on map is 2 cm =25 miles.
Dave measured the distance to the next town at 5 cm.
We have to find the what miles away is the next town.
Let x be the distance in miles away is the next town.
By definition of proportion:
By cross multiply we get;
Simplify:
Divide both sides by 2 we get;
x = 6.25 miles
Therefore, 6.25 miles away is the next town.
