Answer:
£418
Step-by-step explanation:
i answered part of this earlier
julie = 2
kelly = 5
lou = 12
5-2 = 3
3 = £66
£66/3 = £22
2+5+12 = 19
19 x £22 = £418
Answer:
a^7
Step-by-step explanation:
a to the 7th power
I think it would be Six
Because 30 divided by 5 = 6
because 5 times 6 = 30
Approx. 3 1/3 cups. 1 1/2 dozen equals 18 cookies. 90/18=5 . Then you multiply 5 by .666(rep) and it equals =3.3333333(rep) or approx. 3 1/3 cups of sugar.
Answer:
49 eggs.
Step-by-step explanation:
The formula for Margin of Error =
z × standard deviation/√number of samples
z = z score of 98% confidence interval = 2.326
Margin of Error = Half a day = 1/2day = 0.5 day
Standard deviation = 1.5 days
Number of samples = number of eggs he needs to sample = unknown.
Imputing these above values into the formula
Margin of Error = z × standard deviation/√number of samples
0.5 = 2.326 × 1.5/√n
Cross Multiply
0.5 × √n = 2.326 × 1.5
√n = 2.326 × 1.5/0.5
√n = 3.489/0.5
√n = 6.978
Square both sides
(√n)² = 6.978²
n = 48.692484
n ≈ Approximately to the nearest whole number = 49
Therefore, the number of eggs he needs to sample to create the desired interval is approximately to the nearest whole number 49 eggs
