Answer:
as a whole number
Step-by-step explanation:
We calculate the z-score, by evaluating the z value of 0.96/2 = 0.48
The z-score for 0.48 = 2.054
Next, we multiply the z-score by the standard deviation.
i.e. 2.054 x 15 = 30.81
Next, we divide by the margin of error. (from the question, we want to estimate to within 3 minutes of the mean, thus our margin of error is 3.)
i.e. 30.81 / 3 = 10.27
Finally, we square the outcome,
i.e. 10.27^2 = 105.47
Therefore, to estimate within 3 minutes of the mean with 96% confidence, the researcher should take a minimum of 106 samples.
Answer:
C
Step-by-step explanation:
A) 258 x 8145 + 6 = 2101416
And
258 x 8145 = 2101416
So it is NOT the answer because 258 x 8145 + 6 is not 6times than the value of 258 x 8145
B) 6435 x (75452 + 4) =485559360
And
6435 x 75452 = 485533620
So it is NOT the answer beacuse 6435 x (75452 + 4) is not 4 more than the value of 6435 x 75452
D) 9,035 x (432 − 3) = 3876015
AND
9,035 x 432 = 3903120
So it is NOT the answer because 9,035 x (432 − 3) is not 3 less than the value of 9,035 x 432
THE ANSWER IS C BECAUSE :
7,684 − 4,322 = 3362
AND
2 x (7,684 − 4,322) = 6724
And when we do
6724 ÷ 3 =3362
So 7,684 − 4,322 is half value of 2 x (7,684 − 4,322)
