The answer to this question would be: 
<span>a. minus− 1.5, because probability values cannot be less than 0.
</span><span>c. startfraction 64 over 25 endfraction 64 25 , because probability values cannot be greater than 1.

Probability would be in a range of 0-1. There won't be minus probability since the lowest possible will be 0. If the number using percent like 33.3%, then the maximal probability is 100%. If you calculate 64/25 you will got 2.56 which was higher than 1.</span>

Probability of an event is always greater than or equal to 0 & less than or equal to 1,

So, the range of probability is [0, 1]

Here,
a. <span>minus−​1.5, because probability values cannot be less than 0. CORRECT
</span><span>b. ​0.0002, because probability values must be rounded to two decimal places. WRONG 0.0002 is greater than 0 & less than 1
c. startfraction 64 over 25 endfraction 64 25​, because probability values cannot be greater than 1. CORRECT
d. ​33.3%, this is because probability values cannot be greater than 1. WRONG 33.3 % is less than 1 & greater than 0.
e. startfraction 320 over 1058 endfraction 320 1058​, because probability values cannot be in fraction form. f. ​0, because probability values must be greater than 0.</span>WRONG 33.3 % Probability values can be written in fraction, But it's decimal value of fraction should be greater than 0 & less than 1.

Answer:

Problem:

Solve 3x−y=6;y=x−4

Steps:

I will try to solve your system of equations.

y=x−4;3x−y=6

Step: Solvey=x−4for y:

Step: Substitutex−4foryin3x−y=6:

3x−y=6

3x−(x−4)=6

2x+4=6(Simplify both sides of the equation)

2x+4+−4=6+−4(Add -4 to both sides)

2x=2

2x

2

=

2

2

(Divide both sides by 2)

x=1

Step: Substitute1forxiny=x−4:

y=x−4

y=1−4

y=−3(Simplify both sides of the equation)

Answer:

y=−3 and x=1

Step-by-step explanation:

Hope this helped you
