Answer:
9:16
Step-by-step explanation:
The ratio of sides of the lengths of rectangles is 3:4.
- Now since the scale is constant. So the scale ratio of area will be square of the side ratio .
<u>T</u><u>hat </u><u>is </u><u>:</u><u>-</u><u> </u>
→ Ratio of Area = ( 3 : 4)²
→ Ratio of Area = (3/4)²
→ Ratio of Area = 9/16
→ Ratio of Area = 9:16
<h3>
Hence the ratio of areas is 9:16 .</h3>
Answer:
n has to be at least 16577.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
Out of n randomly selected students she finds that that exactly half attend their home basketball games.
This means that 
99% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
About how large would n have to be to get a margin of error less than 0.01 for p
We have to find n for which M = 0.01. So
Rounding up
n has to be at least 16577.
The 4th roots of a^12 = a^3 so we can take out a^3
4th root of 144 = 4th root of 9 * 2 so we can also take out 2
The answer is the first choice.

Answer:
Incomplete Question
Attachment is missing
Step-by-step explanation:
To answer this question, I'll give conditions which satisfy each of the above characteristics of a scatter plot
1. Negative Correlation:
This type of correlation is achieved when either or both values of X and y on the graph decrease
2. Positive Correlation
This is achieved when the slope (value) of both x and y increase
3. Strong Correlation
This is often achieved when there's uniformity in slope x and y.
4. Weak Correlation
This is achieved when there's no uniforms in slope x and y
5. Linear
Linearity refers to whether a data pattern is linear (straight)
6. Nonlinear
Non-Linearity refers to whether a data pattern is curved.
