Answer:
458
Step-by-step explanation:
Margin of error = critical value × standard error
At 99% confidence, the critical value is z = 2.576.
The standard error is σ/√n = 5.4/√n.
Given the desired margin of error is 0.65:
0.65 = 2.576 × 5.4/√n
n = 458
2x+3y=6
- subtract 2x from both sides
3y = -2x + 6
- divide each term by 3

- simplify


- write in slope-intercept form

Answer:
450 cm^3 (Answer D)
Step-by-step explanation:
Volume of a rectangular box of dimensions L, W, H is V = L*W*H. The order in which these measurements are multiplied together is immaterial. Thus,
this particular box has volume V = (5 cm)(9 cm)(10 cm) = 450 cm^3
Answer:
Total earning of Clarissa for the november month is $3840 .
Step-by-step explanation:
As given
Clarissa works in sales for a software company.
Her pay each month varies, because each month she receives a base pay of $2,400.00 plus 8% commission on her sales.
During the month of November, Clarissa had $18,000.00 in sales.
8% is written in the decimal form

= 0.08
Commission price = 0.08 × sales in november month .
= 0.08 × 18000
= $ 1440
Total earning in november month = Base price + Commission price
= $2400 + $ 1440
= $ 3840
Therefore the total earning of Clarissa for the november month is $3840 .
