Am I doing this right?

Lubov Fominskaja [6]

GCF(16, 14) = 2 Note: 14 is not divisible by 4.
GCF(24, 32) = 8 because
24 = 2 x 2 x 2 x 3
32 = 2 x 2 x 2 x 2 x 2 GCF = 2 x 2 x 2 = 8
GCF(10w, 5w) = 5w because the w is a common factor, too.
GCF(16xy, 24xy) = 8xy because x and y are factors common to both
GCF(21ab, 35a) = 7a because a is a common factor, but b is not
GCF(10jk, 15k) = 5k
GCF(3mn, 9mn, 12mn) = 3mn

1: We can say that the total of the length is 9, so:

(3x - 2) + (x-1) = 9

3x + x = 9 - 3

4x = 6

x = 6/4

x = 1.5

SO: (3x - 2) = (3x1.5 - 2)= 4.5 - 2 = 2.5

and

x - 1 = 1.5 - 1 = 0.5

You're welcome!! thank you for the test... revoir ~~

Which of the following statements is not true? A. If the probability of an event occurring is 0, then it is impossible for tha

FromTheMoon [43]

Answer:

C. If the probability of an event occurring is 1.5, then it is certain that the event will occur.

Step-by-step explanation:

Probability is a value between <em>0 and 1</em> (including both values). Thus, to say that there is a probability of 1.5 is not correct, and, therefore, this statement is not true.

We can rewrite the statement as "If the probability of an event occurring is 1, then it is completely certain that the event will occur."

Statement A.

Suppose the event is A. Then, if P(A) = 0, it is completely certain that the event will not occur. It is true.

Statement B.

$\\ if P(A) = 0\;then\;P(\overline{A}) = 1 - 0 = 1$ . Then, the statement is true.

Statement C.

We already explained the <em>statement C is not true</em> because the values for probabilities are between 0 and 1 (including both values). A probability of 1.5 is meaningless as a result.

Statement D.

For the same reason explained in C, the probability can never be a negative value. So, this statement is also true.

what is the volume of the box with a height of 3/2 inches a length of 7/2 inches and a width of 5/2 inches

user100 [1]

The answer would be 13.125 because if you multiply 3/2 by 7/2 and 5/2, then you would get 13.125
