${x}^{2}+10x+25-\left( x+5 \right) \times \left( x+1 \right)$
${x}^{2}+10x+25-\left( {x}^{2}+x+5x+5 \right)$
${x}^{2}+10x+25-\left( {x}^{2}+6x+5 \right)$
${x}^{2}+10x+25-{x}^{2}-6x-5$
$10x+25-6x-5$

User One of the applications of the derivative of a function is its use in Physics, where a function that at every instant t associates the number s(t), this function s is called the clockwise function of the movement. By deriving the time function we obtain the velocity function at time t, denoted by v(t). A body has a time function that determines its position in meters at time t as S(t)=t.³√t+2.t . Present the speed of this body at time t = 8 s.

We plan to test whether the mean mRNA expression level differs between two strains of yeast, for each of 8,000 genes. We will measure the expression levels of each gene, in n samples of strain 1 and m samples of strain 2. We plan to compute a P-value for each gene, using an unpaired two-sample t-test for each gene (the particular type of test does not matter). a) What are the null hypotheses in these tests (in words)? [2] b) If, in fact, the two strains are identical, how many of these tests do we expect to produce a P-value exceeding 1/4? [2]
