41. Degree 3 = x^3 (maximum power in the equation)

Zeros: -1, 1, 3

(x-1)(x+1)(x-3)=f(x) <--- expand as necessary

44. Zeros: -4, 0, 2

(x+4)x(x-2)= f(x) <--- expand as necessary

47. Multiplicity is how many times a particular number is 0 for a given function.

(x+1)(x-1)^3(x-2)^3 <-- not too sure about this one, google definition of multiplicity?

Hope I helped :)

The blueprint for a new swimming pool uses the scale 3/4

Answer:

3 in wide by 4.5 in long.

Step-by-step explanation:

3/4=0.75

I divided the given dimensions by two, so I could multiply .75 by the sets of twos instead of dividing 3/4 by two and multiplying that by 12 and 8.

.74 x 4 = 3

.75 x 6 = 4.5

A counselor records the number of disagreements (per session) among couples during group counseling sessions. If the number of d

Shalnov [3]

Answer:

$P(X>4)=P(\frac{X-\mu}{\sigma}>\frac{4-\mu}{\sigma})=P(Z>\frac{4-4.4}{0.4})=P(z>-1)$

And we can find this probability with the complement rule:

$P(z>-1)=1-P(z$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the disagreements of a population, and for this case we know the distribution for X is given by:

$X \sim N(4.4,0.4)$
