g The following scatterplot shows the 20 top-selling cars with their weight on the horizontal axis and their miles per gallon (m
pg) on the vertical axis. The overall direction of this data is __________. The strength of the association is __________. a.) positive; weak b.) positive; strong c.) negative; strong d.) negative; weak
1 answer:
scatterplot relating to the question is attached below.
Answer: Negative ; Strong
Step-by-step explanation:
From the picture of the scatter plot Given, it could be observed that the trend of the scatter points exhibits a negative gradient as the points on the graph slopes downward depicting that an inverse relationship exists between the two variables. With weight decreasing as miles per gallon increases. The relationship between the two variables depicted by the scatter plot is strong as the slope of the point is looks moderately steep.

Answer:
66.6% (see below)
Step-by-step explanation:
Each sphere 4/3r²=4/3
(4²)=268.08cm³
Assuming the tube is the same width and height as the three spheres,
V=r²h=
(4²)24=1206.37
The three spheres are 268.08*3=804.24cm³
The tube is 1206.37cm³
<u>I’m not sure if your question is asking the percentage of the tube that’s filled, or the percentage that’s unfilled.</u>
Filled: 804.24÷1206.37=0.66666=66.6%
Unfilled: 1206.37-804.24=402.13
402.13÷106.37=0.33333=33.3%
The 99% confidence interval for the population proportion is given by
Given that 52% = 0.52 is the standard proportion and the standard error is 2.4% = 0.024.
Therefore, the <span>99% confidence interval for the fraction of u.s. adult twitter users who get some news on twitter is given by
</span>Therefore, the <span>99% confidence interval for the fraction of u.s. adult twitter users who get some news on twitter is 45.82% and 58.18%.
The interpretation of the confidence interval</span> is as follows: "We are 99% confident that the fraction of U.S. adult twiter users who get some news on twitter is between 45.82% and 58.18%.
