The probability of certainty is 100%=1

If Probability(p)=0.34

then

Probability (p) +cProbability (!p) = 1 where !p is used to denote "not "p

0.34+Probability(!p)=1

Probability(!p)=1−0.34=0.66

Martin’s gross pay is $30,135 per year. His federal income tax percent that is withheld from his paycheck is 15%. The amount of
OLEGan [10]

Answer:

Martin will get a refund of about $370.

Step-by-step explanation:

The gross pay of Martin = $30135

The federal income tax percent that is withheld from his paycheck is 15%, this becomes = 0.15*30135=4520.25

As given, he owes the government after federal deductions is $4,150.

So, amount that exceeds this amount = 4250.25-4150=370.25

Means, this $370.25 is to be refunded to Martin.

Hence, the true option is Martin will get a refund of about $370.

Use the Distributive Property to find (z−5)(z+3).
Anastasy [175]
Consider, (z-5)(z+3). Let's say a = z-5 then the problem reduces to a(z+3)=za+3a. (Do you understand this step?)

So then replacing a again with our definition we get, z(z-5)+3(z-5)=z^2-5z+3z-15=z^2-2z-15.

Look at this graph:
EastWind [94]
<h2>Answer:</h2>

The Slope is \frac{2}{3}\\

<h2>Explanation:</h2>

Notice that both the points, (0,20) and (20,50), are on the line. So we can use those points to calculate the slope. Recall that that slope of the line m can be calculated by \frac{y_2 -y_1}{x_2 -x_1}\\ if we have the points, (x_1,y_1) and (x_2,y_2).

<h3>Calculating for the slope of the line:</h3>

Given:

(0,20)

(20,50)

m = \frac{50 -20}{20 -0} \\ m = \frac{30}{20} \\ m = \frac{2}{3}
