Given that after a discount of 40% a furniture was bought for $438. The original price of the furniture will be calculated as follows:
discount=40%
new percentage price=100-40=60%
Original percentage price=100%
New buying price=$438
therefore, the original price was:
100/60×438
=$730
The original price was $730
Answer:
Step-by-step explanation:
Given that for a sample size of 25, sample mean = 102 lbs. and sample std deviation = 10 lbs.
(Right tailed test)
Given that we assume population is normally distributed
Test statistic:
Mean difference = +2
Std error of sample = 
t = test statistic = Mean diff/Std error 
degree of freedom
Critical value of t = 1.711
Our test statistic >1.71
Accept alternate hypothesis
Because there is significant difference between the test statistic and test statistic lies above critical value.
The explicit rule will be an = 1/3 + (n - 1)
<h3>An explicit formula for a sequence</h3>
Given the following information
a2 = a1 + 1
a2 = 4/3
For the third term
a3 = a2 + 1
a3 = 4/3 + 1
a3 = 7/3
The resulting seqence is 1/3, 4/3, 7/3
The sequence is an arithmetic sequence
a = 1/3
d = 1
The explicit rule will be an = 1/3 + (n - 1)
