All you need to do is find the unit rate by dividing 32 ➗ 3, and you get a unit rate of 10 2/3. Next, multiply 10 2/6 by 6 and 9 and you can find your answer.

I did not tell you the answer but I hope this helps you figure it out

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 find x in the proportion: 4/x=5/9.

Nonamiya [84]

First multiply 4 so x is on its own.

5/9 multiplied by 4/1 is 20/9.

20/9 simplifies to 2 and 2/9.

x = 2 and 2/9

Hope this helped, and please mark brainliest! :)
