Answer:
27
Step-by-step explanation:
Let the number to find out be 'x'
Therefore,
according to the condition given question, we get the equation as
Now,
squaring both the sides, we get
2x - 5 = 49
on adding 5 both sides, we get
2x - 5 + 5 = 49 + 5
or
2x = 54
or
x =
or
x = 27
Hence, the number is 27

Answer:
Step-by-step explanation:
Given that population average is 0.8 ampere
Sample size = 9
Sample mean x bar = 1.34 A
Sample std dev s = 0.48
(one tailed test)
Mean difference -
Std error =
t test can be used since sigma is not known and sample size small
t statistic = mean diff/std error = 3.5
df = 8
p value = 0.00404
1. Over a period of 6 years (from 1980 to 1986) the house gained a value of 12000 dollars (109k-97k). 12000/6 gives you a rate of 2000 dollars per year. Because the initial price at t=0 is 97000, the function is 97000+2000t
