Answer:
Tues=8 Weds=24 Thurs=120
Step-by-step explanation:
The question can be modeled by the equation x+3x+15x=152
x is the amount sold on tuesday, 3x is 3 times the amount sold on tuesday so it represents wednesday and 15x represents thursday as it is 5 times the amount sold on wednesday.
Now we just need to solve for x to figure out how many he sold each day.
x+3x+15x=19x
19x=152
x=152/19
x=8
To find the amount sold on each day just mulitiply x by the coefficient
Tuesday = x = 8
Wednesday = 3x = 3*8 = 24
Thursday = 15x = 15*8 = 120
Answer:
The sample size is 183.
Step-by-step explanation:
Given:
σ = $1050, ppulatin standard deviation
99% confidence interval
Accuracy = +/- $200
The accuracy is given by
z*(σ/√n)
where
z* = 2.576 for 99% confidence level (from tables)
n = sample size
Therefore
2.576(1050/√n) = 200
√n = (2.576*1050)/200 = 13.524
n = 182.9
<em>The sample size is 183</em>
