Snapdragon plants have a gene that determines the presence of chlorophyll. The dominant allele (C) causes the plant to make chlo

rophyll, while the recessive allele (c) makes none. Snapdragons that are homozygous dominiant (CC) are green, whereas those that are heterozygous (Cc or cC) are yellow. The homozygous recessive plants die almost immediately due to lack of chlorophyll. If a healthy adult snapdragon is chosen at random from a large population of offspring of a heterozygous cross, about 1/3 will have zero copies of the recessive, and 2/3 will have one copy. Let X be a RV that represents the number of copies of the recessive allele. Eight healthy Snapdragon plants were chosen at random from a large population of offspring of a heterozygous cross.

Answer: i)For X = (0,1) then P(x) = (1/3, 2/3)

              ii) Then p=(2/3) as n=8

              iii) 0.06828

Step-by-step explanation:

Use binomial distribution:

Probability of being yellow (by having 1 recessive allele) is 2/3. This is a binomial distribution with p=2/3. And since there are 8 selections, our n is 8. So p=(2/3), n=8.

Recall that in binomial distribution P(X=x) = C(n,x) × p^x × (1-p)^n-x.

So for 3 out of 8, it means x=3 and n=8.  

Our equation becomes P(exactly three Snapdragon are yellow) = P(X=3) = (8C3) × (2/3)³ × (1/3)5 = 0.06828

X=7 since you need to make an equation and in one hour you make $7. Don’t include the 1 as in 1x cause that’s incorrect

Which expression is equivalent to 4(7 + 8)?<br><br>A) 11+8<br>B) 11+12<br>C) 28+12<br>D) 28+32​
andreev551 [17]
To do this we take the outlier off the parenthesis (the 4) and multiply it by the two numbers inside the parenthesis...

4*7 + 4*8

28+32

Someone please explain this question PART "b) i" ONLY!!!

<h3>Answer:   (n-1)^2</h3>

This is because we have a list of perfect squares 0,1,4,9,...

We use n-1 in place of n because we're shifting things one spot to the left, since we start at 0 instead of 1.

In other words, if the answer was n^2, then the first term would be 1^2 = 1, the second term would be 2^2 = 4, and so on. But again, we started with 0^2 = 0, so that's why we need the n-1 shift.

You can confirm this is the case by plugging n = 1 into (n-1)^2 and you should find the result is 0^2 = 0. Similarly, if you tried n = 2, you should get 1^2 = 1, and so on. It appears you already wrote the answer when you wrote "Mark Scheme".

All of this only applies to sequence A.

side note: n is some positive whole number.
