A circle with a radius of 4cm sits inside a circle with a radius of 11cm
What is the area of the shaded region?
Round your final answer to the nearest hundredth.
Answer: 329.86 cm
The answer is= there are 126 5p coins
the reason for this is that
-630 is simplified to 5,
-so 1/5 is really 126/630,
(630 divided by 5 is 126)
- and so 2/5 is 126 x 2 =252/630
- there are only 3 parts left, and if 1p has more parts than 5p,
-then 1p takes up 2/5 of the bag
-and 5p takes up 1/5 of the bag
Answer:
210
Step-by-step explanation:
GCF(30,42) = 6
LCM(30,42) = ( 30 × 42) / 6
LCM(30,42) = 1260 / 6
LCM(30,42) = 210
Answer:
h(-6) = 2
Step-by-step explanation:
-x - 4 =
-(-6) - 4 = 2
6-4=2
Solution :
To claim to be tested is whether "the mean salary is higher than 48,734".
i.e. μ > 48,734
Therefore the null and the alternative hypothesis are
![$H_0 : \mu = 48,734$](https://tex.z-dn.net/?f=%24H_0%20%3A%20%5Cmu%20%3D%2048%2C734%24)
and ![$H_1 : \mu > 48,734$](https://tex.z-dn.net/?f=%24H_1%20%3A%20%5Cmu%20%3E%2048%2C734%24)
Here, n = 50
![$\bar x = 49,830$](https://tex.z-dn.net/?f=%24%5Cbar%20x%20%3D%2049%2C830%24)
s = 3600
We take , α = 0.05
The test statistics t is given by
![$t=\frac{\bar x - \mu}{\frac{s}{\sqrt n}}$](https://tex.z-dn.net/?f=%24t%3D%5Cfrac%7B%5Cbar%20x%20-%20%5Cmu%7D%7B%5Cfrac%7Bs%7D%7B%5Csqrt%20n%7D%7D%24)
![$t=\frac{49,830 - 48,734}{\frac{3600}{\sqrt 50}}$](https://tex.z-dn.net/?f=%24t%3D%5Cfrac%7B49%2C830%20-%2048%2C734%7D%7B%5Cfrac%7B3600%7D%7B%5Csqrt%2050%7D%7D%24)
t = 2.15
Now the ">" sign in the
sign indicates that the right tailed test
Now degree of freedom, df = n - 1
= 50 - 1
= 49
Therefore, the p value = 0.02
The observed p value is less than α = 0.05, therefore we reject
. Hence the mean salary that the accounting graduates are offered from the university is more than the average salary of 48,734 dollar.
