Is the identity
?
If so, all you have to do is recognize that in your example, a = 2
Substitute into the identity
Recognizing an identity can be helpful in that it can save time when expanding.
If you are asking for just an arbitraty sequence, here it goes:
Answer:
$15600
Step-by-step explanation:
Minimum number of samples can be calculated using the formula:
N≥ where
- N is the sample size
- z is the corresponding z-score for 95% confidence level (1.96)
- s is the standard deviation of the calorie consumption (450 cal.)
- ME is the margin of error that the researcher is willing to accept. (50 cal)
N≥ =311.2
Therefore, minimum required sample size for 50 cal standard error in 95% confidence is 312
Since the survey costs $50 for each person then the survey costs minimum
50*312=$15600
Add 3 to each side, then cross out the three. The equation can be rewritten as 2x+4x=24
2x plus 4x is 6x, making our equation 6x=24.
Divide by 6 on each side to get the answer x is 4. Your answer is 4
