Answer and Step-by-step explanation:

Distribute the s, then distribute the t, then finally simplify.

$5s^2 - 7st\\5st - 7t^2\\\\5s^2 - 7st + 5st - 7t^2\\\\5s^2 - 2ts = 7t^2$ <-- This is the answer.

To find the percentage,we need to form a fraction first:

The nominator would be: the students who have not blue eye and were not wearing orange at the same time (50)

The denominator: students with not blue eyes (20)

Hence we can form the fraction: 20/50

To find the percentage, we can multiply the fraction by 100%:

20/50x100%

=2/5 x 100%

= 200/5 %

= 40%

Therefore the answer is 40%.

Hope it helps!

A botanist has developed a new hybrid cotton plant that can withstand insects better than other cotton plants. However, there is

True [87]

Answer:

$n = 3000$ seeds planted in the farm

From these 3000 we know that only 2200 germinated

In order to determine the probability that a seed will germinate we can use the definition of probability given by:

$p =\frac{Possible}{Total}$

From this definition we need to divide the possible cases by the total cases and for this case if we replace we got:

$p =\frac{2200}{3000}= 0.733$

So then the probability that the seed will germinate is 0.733 from the sample data obtained

Step-by-step explanation:

For this case we know that the sample size is:

$n = 3000$ seeds planted in the farm

From these 3000 we know that only 2200 germinated

In order to determine the probability that a seed will germinate we can use the definition of probability given by:

$p =\frac{Possible}{Total}$

From this definition we need to divide the possible cases by the total cases and for this case if we replace we got:
