10th b.day=300
11th=300+200=500
12th=500+200=700
13th=700+200=900
14th=900+200=1100
15th=1100+200=1300
16th=1300+200=1500
17th=1500+200=1700
18th=1700+200=1900
So,the daughter will receive an amount of 1900..
Thanks!
Answer:
The 95% confidence interval for population mean is (18.19, 23.81).
Step-by-step explanation:
The confidence interval for population mean using the Student's <em>t</em>-distribution is:
Given:
The critical value of <em>t</em> for <em>α </em>= 0.05 and degrees of freedom, (<em>n</em> - 1) = 19 is:
Compute the 95% confidence interval for population mean as follows:
Thus, the 95% confidence interval for population mean is (18.19, 23.81).
Okay so I wont be able to show the row here but I will try my best.
7(5x-4y=28) = 35x-28y=196
-5(7x+5y=18) = -35x-25y=-90
= -53y=106
= y=-2
5x-4(-2) =28
5x+8=28
5x=20
x=4

Answer:
t = 3
Step-by-step explanation:
Given
- 3 (t - 2) + 7t = 9t - 9 ← distribute left side and simplify
- 3t + 6 + 7t = 9t - 9
4t + 6 = 9t - 9 ( subtract 9t from both sides )
- 5t + 6 = - 9 ( subtract 6 from both sides )
- 5t = - 15 ( divide both sides by - 5 )
t = 3
