A packet of garden seeds contains 250 seeds. The information printed on the packet indicates that the germination rate for this

Westkost [7]

Answer:

Expectation=240

standard deviation=3.098

Step-by-step explanation:

This is a binomial probability function with n=250 and probability of success is 96%

-The expected value is calculated as:

$E(X)=np\\\\=250\times 0.96\\\\=240$

Hence, the expected germination is 240 seeds

b. From a above, we have the value of p=0.96 and n=250.

The standard deviation of germination is therefore calculated using the formula:

$\sigma=\sqrt{np(1-p)}, \ \ \ \\\\=\sqrt{250\times 0.96(1-0.96)}\\\\\\=3.098$

Hence, the standard deviation of germination is 3.098

Please help me in the question of commission ! Grade - 9 .

AlladinOne [14]

Answer:

Step-by-step explanation:

Commission for amount Rs. 5,00,00 = $\frac{2}{100}*500000$

= 2* 5000

= Rs. 10,000

total commission = Rs. 32,000

Remaining commission = 32500 - 10000

= Rs. 22500

Let remaining amount of the restaurant = Rs. x

Commission on Rs. x = 22500

3% of x = 22500

$\frac{3}{100}*x=22500\\\\x=22500*\frac{100}{3}\\\\x = 7500*100$

x = Rs. 750000

Price of the restaurant = 750000 + 500000

=Rs . 1250000
