10/14 = 5/7.
5/7 is your answer. Divide both the numerator and the denominator by a number that they both have in common - 2.
Answer:
YES
Step-by-step explanation:
Answer:
c. 0.778 < p < 0.883.
Step-by-step explanation:
The formula for confidence interval for proportion =
p ± z score × √p(1 - p)/n
p = x/n
n = 195, x = 162
z score for 95% confidence Interval = 1.96
p = 162/195
p = 0.8307692308
p ≈ approximately equal to = 0.8308
0.8308 ± 1.96 × √0.8308 × (1 - 0.8308)/195
0.8308 ± 1.96 ×√0.8308 × 0.1692/195
0.8308 ± 1.96 × √0.0007208788
0.8308 ± 1.96 × 0.0268491862
0.8308 ± 0.052624405
Confidence Interval
= 0.8308 - 0.052624405
= 0.778175595
Approximately = 0.778
= 0.8308 + 0.052624405
= 0.883424405
Approximately = p
0.883
Therefore, the confidence interval for this proportion = (0.778, 0.883) or option c. 0.778 < p < 0.883
option (D) 28 √6 is the answer
Explanation :
p =3√6 + 2√24 + 7√54
3√6 + 2√2×2×6+ 7√3×3×6
3√6 +2 ×2√6 + 7 ×3√6
3√6 +4√6 + 21√6
28√6
Answer:
The total amount customer paid during those 3 years is $1685
Step-by-step explanation:
We are supposed to find the total amount customer paid during those 3 years
Customer made a tax payment = $1250
He received a refund of amount = 550
So, amount paid by him = 1250-550
Amount paid by him ==700
Now again He made a tax payment = $925
Processing fee = $60
So, Total Amount paid by him =700+925+60
Total Amount paid by him =1685
Hence the total amount customer paid during those 3 years is $1685
