Answer:
The number of radians in the central angle is 0.375
Step-by-step explanation:
* Lets study the radians rule of the circle
- If the measure of the central angle is Ф radians
- If the length of the arc subtended by Ф is L
∴ L = r Ф
* Lets look to the our problem
∵ The radius = 8 inches
∵ The measure of the central angle is Ф
∵ The length of the intercepted arc of Ф = 3 inches
* Use the rule L = r Ф ⇒ divide both sides by r
∴ Ф = L/r
∴ Ф = 3/8 = 0.375 radians
* The number of radians in the central angle is 0.375
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
(left tailed test at 10% significance level)
p difference = -0.02
STd error of p =
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
Ask your teacher he or she will know
It’s either a or c sorry if there wrong!
This shape would be an equilateral triangle, hope that helps!!
