Hello there!
By multiplying them altogether, this would the result in (-0.054).
We first do the first two problems.
0.04*-0.9.
From this solution, we multiply this by 1.5, and from this we get -0.054
Answer:
the cost of the damaged book is 11.25
Step-by-step explanation:
since it is 25% off the 100% cost it is dicounted to 75% of the price
multiply full price by 75% (.75) to get 11.25
Answer:
When a line segment is bisected into 2 halves, the two halves are equal. In this case, when AB is bisected by CD, AE and BE would be equal and each point on CD should be equidistant from point A and point B. Therefore, AC = AB.
Answer:
Decision rule for rejecting is
reject H0 is test statistic <-1.233
Step-by-step explanation:
Given that a sample of 1300 computer chips revealed that 27% of the chips do not fail in the first 1000 hours of their use, as against company literature of 29%
To test this we create hypotheses as
![H_0: p = 29%\\H_a: p](https://tex.z-dn.net/?f=H_0%3A%20p%20%3D%2029%25%5C%5CH_a%3A%20p%20%3C27%25)
(left tailed test at 10% significance level)
p difference = -0.02
STd error of p = ![\sqrt{0.29*0.71/1300} \\=0.0126](https://tex.z-dn.net/?f=%5Csqrt%7B0.29%2A0.71%2F1300%7D%20%5C%5C%3D0.0126)
Test statistic = p diff/std error = -0.1587
For 10% significance level for right tailed test we can reject H0 if
test statistic <-1.645
Decision rule for rejecting is
reject H0 is test statistic <-1.233
