f(x)=8−4x−x3 g(x)=x2+7x−9 Find f(x)+g(x). Select one: a. x3+x2+3x−1 b. −x3+x+3x−1 c. −x3+x2+11x−9 d. 8x2+3x−9x3
vovangra [49]

Answer:

B

Step-by-step explanation:

We are given the two functions:

f(x) = 8 - 4x - x^3\text{ and } g(x) = x^2 + 7x - 9

And we want to find:

f(x) + g(x)

Substitute:

= (8 - 4x - x^3) + (x^2 + 7x - 9)

Rewrite:

= (-x^3) + (x^2) + (7x - 4x) + (8 - 9)

Combine like terms:

= -x^3 + x^2 +3x -1

In conclusion:

f(x) + g(x) =  -x^3 + x^2 +3x -1

Hence, our answer is B.

Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. Thi
Mariana [72]

Answer:

a. Mean: 9.5.

Standard deviation: 2.18.

b. The critical value for signficantly low girl births is 5.14.

The critical value for signficantly high girl births is 13.86.

Step-by-step explanation:

a) If we take a sample of 19 births, all with individual probability of 0.5, we have a random binomial variable with n=19 and p=0.5.

This random variable will have mean and standard deviation calculated as:

\mu=n\cdot p=19\cdot0.5=9.5\\\\\sigma=\sqrt{np(1-p)}=\sqrt{19\cdot0.5\cdpot0.5}=\sqrt{4.75}=2.18

b) Range rule of thumb: The standard deviation is approximately a quarter of the range, difference between the maximum and minimum value.

The range rule of thumb tells us that the expected minimum and maximum value are 2 standards deviation below or above, respectively, from the mean.

Then, the extreme expected values are:

Min=\mu-2\sigma=9.5-2\cdot2.18=9.5-4.36=5.14\\\\Max=\mu+2\sigma=9.5+2\cdot2.18=9.5+4.36=13.86

The critical value for signficantly low girl births is 5.14.

The critical value for signficantly high girl births is 13.86.
