The correct answer should be 20% because u were 80% certain he would remember so that means ur 20% certain he would forget
To find the probability simply divide the number of blue marbles by the total:
SO, 3 / 7 = 0.42857
p = 0.429
Answer:
The scale factor is 1.
Step-by-step explanation:
Let k be the scale factor of a dilation of triangle ABC to form the image triangle A'B'C'.
The dilation is a magnification if

In this case, the preimage will be similar to the image triangle.
If

the dilation is a reduction. The image and pre-image will still be similar.
But if

the image is the same as the preimage.
We say the pre-image is congruent to the image triangle.
Multiplying the linear expressions, the correct sequence is given as follows:
<h3>How are linear expressions multiplied?</h3>
They are multiplied applying the distributive property, in which all the terms are multiplied and the like terms are combined.
Hence:
5x(-3 -7x)
(5x)(-3) + (5x)(-7x)
-15x - 35x²
Hence the last option is correct.
