Answer:

9.11 x 10^-28

Step-by-step explanation:

if you divide 9.11 x 10^-28 by 1.67 x 10^-24 you get .000546

if you divide 1.67 x 10^-24 by 9.11 x 10^-28 you get 1,833

therefore, 1.67 x 10^-24 is 1833 times greater than the other value

Volgvan

Answer: We reject the null hypothesis, and we use Normal distribution for the test.

Step-by-step explanation:

Since we have given that

We claim that

Null hypothesis : H_0:\mu\geq 50000

Alternate hypothesis : H_1:\mu

There  is 5% level of significance.

\bar{X}=46800\\\\\sigma=9800\\\\n=29

So, the test statistic would be

z=\dfrac{\bar{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\z=\dfrac{46800-50000}{\dfrac{9800}{\sqrt{29}}}\\\\z=-1.75

Since alternate hypothesis is left tailed test.

So, p-value = P(z≤-2.31)=0.0401

And the P-value =0.0401 is less than the given level of significance i.e. 5% 0.05.

So, we reject the null hypothesis, and we use Normal distribution for the test.

Ronch [10]

Answer:

Value of f (Parapedicular) = 7√6

Step-by-step explanation:

Given:

Given triangle is a right angle triangle

Value of base = 7√2

Angle made by base and hypotenuse = 60°

Find:

Value of f (Parapedicular)

Computation:

Using trigonometry application

Tanθ = Parapedicular / Base

Tan60 = Parapedicular / 7√2

√3 = Parapedicular / 7√2

Value of f (Parapedicular) = 7√2 x √3

Value of f (Parapedicular) = 7√6
