Answer:
3
Step-by-step explanation:
The scale factor of ABC to DEF is the number you need to multiply a corresponding side of ABC to get one of DBC. We are given the two triangles are similar, so we can say that sides AB and DE are proportional. We are looking for the number we need to multiply AB by to get DE. From this relation, we can get the equation:
AB * x = DE
where x is our scale factor. We can substitute in the values of AB and DE, and solve for x:
5x = 15
x = 3
Therefore, the scale factor is three. This means that you can multiply any side of ABC by 3 to get a side of DEF.
The probability of the ball being white in the first basket is: 2/9
The probability of the ball being white in the second basket is: 3/13
Work:
First off, in basket 1, there are 9 balls in all, 2 of which are white, 7 of which are yellow. So, to find your denominator (If doing this in fraction form), you add up the number of balls. In this case, the first basket has 2 white balls and 7 yellows balls, so 2 + 7 = 9. To find your numerator (Which is the specified color ball probability), you just simply choose the number of balls it is asking for. In this question, it is asking for the probability of white balls in each basket. In basket one, there are 2 out of 11 balls in total. So, your answer would be that there are 2/11 white balls in basket 1.
I am not going to say this same process for the 2nd basket because it takes some time, but I hope this helps! :)
The point-slope form of the equation of a line of slope m through point (h, k) is given by
... y - k = m(x - h)
Substituting your given values, you have ...
... B. y - 5 = 3(x - 2)
