Step-by-step explanation:
Answer:
D.121
Step-by-step explanation:
R=165-0.75a for men,
where a represents the person’s age. What would the desirable heart rate be for a 46 year old woman?
a. 113 beats per minute
b. 172.9 beats per minute
c. 143.7 beats per minute
d. 63 beats per minute
Answer:
Option a is correct.
The desirable heart rate be for a 46 year old woman is, 113 beats per minute.
Step-by-step explanation:
Here, R represents a person's desirable heart rate(in beats per minute)
and a represents the person's age.
The desirable heart rate of a person's can be approximated by the formulas;
For women:
......[1]
For men:
......[2]
To find the desirable heart rate be for a 46 year old woman.
⇒
Substitute in [1] we get;
beats per minute
Therefore, 113 beats per minute would the desirable heart rate be for a 46 years old woman.
Answer:the correct answer is A) 0.59.
To find the margin of error at a 95% confidence level, we can use the formula:
Margin of Error = Critical Value * Standard Deviation
First, let's find the critical value. Since we are working with a 95% confidence level, we can use a z-score table to find the corresponding critical value.
For a 95% confidence level, the critical value is approximately 1.96.
Next, we need to find the standard deviation. In this case, the standard deviation is represented by "s" which is given as 3.
Now we can calculate the margin of error:
Margin of Error = 1.96 * 3 = 5.88
Rounding this to two decimal places, the margin of error is approximately 5.88.
Therefore, the correct answer is A) 0.59.
The margin of error for a 95% confidence interval with a sample size of 24 and a standard deviation of 3 is approximately 1.2 (or 1.23 when rounding up to the next available answer). This is calculated using the formula M = Z * (s/√n), where M is the margin of error, Z is the z-score, s denotes standard deviation, and n represents the sample size.
The formula for calculating the margin of error at a 95% confidence level is M = Z * (s/√n), where M is the margin of error, Z is the z-score, s is the standard deviation, and n is the sample size.
Since we're finding the margin of error for the 95% confidence level, we use a z-score of 1.96: the value that corresponds to 95% confidence in a standard normal distribution. In your case, n=24, s=3, and z=1.96. Thus, the margin of error is M = 1.96 * (3/√24).
After performing the arithmetic, you'll find that the margin of error, rounded to two decimal places, is approximately 1.2 (1.21 to be more accurate). Thus, the closest answer is B) 1.23.
