Step-by-step explanation:
Complementary angles mean that the sum of the angles add up to . We can use algebra to solve for and then to determine .
(substitution)
∴
Hope this helps :)
So to find the other endpoint you need to see how far the first endpoint is to the midpoint. In X's place we have a total distance of
5- (-3)= 8 place away from one another so
5+8= 13
while in the y's case
5-2=3 place away from one another so
2-3= -1
so your order pair is
(13,-1)
NAMASTE :)
HERE IS YOUR ANSWER:
aeroplane Travel in 3 hrs = 105 miles
aeroplane travel in 1 hr = 105/3 = 35 miles
aeroplane travel in 11 hrs = 35 ×11 = 385 miles
Answer:
With 99% confidence the proportion of all smart phones that break before the warranty expires is between 0.041 and 0.069.
Step-by-step explanation:
We have to calculate a 99% confidence interval for the proportion.
The sample proportion is p=0.055.
The standard error of the proportion is:
The critical z-value for a 99% confidence interval is z=2.576.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 99% confidence interval for the population proportion is (0.041, 0.069).
