Answer:
- Hypotenuse
- Leg 1
- Leg 2
Step-by-step explanation:
Represent the dimensions as:
So, we have:
Required
Determine the dimensions
Apply Pythagoras theorem
This gives:
Open bracket
Collect Like Terms
Solve for S2
Recall that:
Hence, the dimensions are:
Answer:
The sample size used to compute the 95% confidence interval is 1066.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population proportion is:
The 95% confidence interval for proportion of the bank's customers who also have accounts at one or more other banks is (0.45, 0.51).
To compute the sample size used we first need to compute the sample proportion value.
The value of sample proportion is:
Now compute the value of margin of error as follows:
The critical value of <em>z</em> for 95% confidence level is:
Compute the value of sample size as follows:
Thus, the sample size used to compute the 95% confidence interval is 1066.
Answer:
Is this all of the question?
Step-by-step explanation:
Answer:
A rational number is a number that can be expressed as a fraction (ratio). This includes whole numbers, square roots that can be solved evenly, negatives, decimals, and repeating decimals that can be solved with a fraction.
- ↔ .5
- 5 ↔ 5.0
- ↔ 2.0
- -13 ↔ -13.0
- 0.38462... ()
An irrational number is a number that is NOT rational. It's the complete opposite!
- π ↔ 3.14159
- .13133133...
- ↔ 0.86603...
- - ↔ -2.23607...
- ↔ 2.23607...
Hope this helps!!!
Answer:
y = (-3/4)x + 15
Step-by-step explanation:
The slope of the given line is 4/3. The slope of a line perpendicular to this given line is the negative reciprocal of 4/3, which comes out to -3/4.
Now that we have both the slope and y-intercept of the new line, we're ready to write out the desired equation in slope-intercept form:
y = (-3/4)x + 15
