Answer:
42° and 138°.
Step-by-step explanation:
Here we use the identity that
.
Now, to find
, we make use of the inverse sine function:
![x = sin^{-1}(0.0091)](https://tex.z-dn.net/?f=x%20%3D%20sin%5E%7B-1%7D%280.0091%29)
![\boxed{ x = 42^o.}](https://tex.z-dn.net/?f=%5Cboxed%7B%20x%20%3D%2042%5Eo.%7D)
Another solution to this is
Thus, the values of
in the interval
for which
are 42° and 138°.
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
![H_o: x bar =0.8\\H_a: x bar >0.8](https://tex.z-dn.net/?f=H_o%3A%20x%20bar%20%3D0.8%5C%5CH_a%3A%20x%20bar%20%3E0.8)
(one tailed test)
Mean difference - ![1.34-0.8 =0.54](https://tex.z-dn.net/?f=1.34-0.8%20%3D0.54)
Std error = ![\frac{s}{\sqrt{n} } =0.16](https://tex.z-dn.net/?f=%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%20%7D%20%3D0.16)
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
Complete question:
Traders often buy foreign currency in hope of making money when the currency's value changes. For example, on a particular day, one U.S. dollar could purchase 0.8167 Euros, and one Euro could purchase 145.8038 yen. Let f (x )represent the number of Euros you can buy with x dollars, and let g (x )represent the number of yen you can buy with x Euros.
Find a function that relates dollars to Euros
Find a function that relates Euros to Yes
Answer:
1. Since with one dollar, you can purchase 0.8167 euro.
thus the function will be direct.
if dollar is x
then f (x) = 0.8167 x
2. Since with one Euro, you can purchase 145.8038 yen.
thus the function will be direct.
if euro is y
then f (y) = 145.8038 y

▹ Answer
<em>a = 8</em>
▹ Step-by-Step Explanation
a/4 + 4 = 6
Multiply both sides:
a + 16 = 24
Subtract 16 from both sides:
16 - 16 = a
24 - 16 = 8
a = 8
Hope this helps!

It would take 2.61 hours to fly from Dallas to Boston at 775 mph.
Since the time it takes to fly from Dallas to Boston varies inversely with the speed of the plane, to determine, if the trip takes 4.75 hours at 427 mi / h, how long would it take at 775 mi / h, the following calculation must be performed:
- (427 x 4.75) / 775 = X
- 2028.25 / 775 = X
- 2.61 = X
Therefore, it would take 2.61 hours to fly from Dallas to Boston at 775 mph.
