Answer:
Step-by-step explanation:
multiply .20 with 40
which gets you 8
subtract 8 from 40
which is 32
multiply .05 with 32
which is 1.6
subtract 1.6 from 32 which gets you $30.40
Answer:
$397.99
Step-by-step explanation:
105*100 = 1.05
1.05^20 = 2.65329770514
2.65329770514* 150 = 397.99
Answer:
B
Step-by-step explanation:
A=1/2*(10+20)*5
=1/2*30*5
=75m*2
Solution :
Given :
Sample mean,
Sample size, n = 40
Standard deviation, s = 83.2
∴ The null hypothesis is
Alternate hypothesis is
Test statistic :
z = 0.813
Now at α = 0.05, for a right tailed,
Since, , we fail to reject the null hypothesis.
