Answer:

  (f\cdot g)(x)=\dfrac{7x-21}{x+4}

Step-by-step explanation:

(f\cdot g)(x)=f(x)\cdot g(x)=(x^2-7x+12)\cdot\dfrac{7}{x^2-16}\\\\=7\dfrac{(x-3)(x-4)}{(x+4)(x-4)}=\dfrac{7(x-3)}{x+4}\\\\=\dfrac{7x-21}{x+4}

Suppose medical records indicate that the length of newborn babies(in inches) is normally distributed with a mean of 20 and a st
Nadusha1986 [10]

Answer:

P=0.954 or 95.4%

Step-by-step explanation:

Using the formula for the standardized normal distribution to find Z:

Z=\frac{X-\mu}{\sigma}

Where μ is the mean (μ=20) and σ is the standard deviation (σ=2.6).  

Z_{1} =\frac{14.8-20}{2.6}=-2.0

Z_{1} =\frac{25.2-20}{2.6}=2.0

In the table of the normal distribution, we can look for positive values z, and these values are going to represent the area under the curve between z=0 and the values searched. the negatives values are found by symmetry (with the corresponding positive value but remember this area is under the left side of the curve).  To find a value in the table, find the units in the first column and the follow over the same row till you find the decimals required.

P_1=0.4772

P_2=0.4772

P_1 represents the probability of length being between 14.8 and 20 (the mean) and P_2 represents the probability of length being between 20 and 25.2, The requested probability is the sum of these two.

P=P_1+P_2=0.954
