9/20 because you can divide them in half but you can divide them any further.
If you
3 x 3 / 8
you
3× 3 = 9
in you put
9/8
The answer is option b because by substituting the values corresponding to x = -2 and x = -3 then the result of the equation is zero. Therefore, it is shown that for this equation both roots of the polynomial are correct.
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
