2) Given that XY || AC, what is YC if BX = 10, BA = 15, and BY = 8?
1 answer:
The parallel lines XY and AC is an illustration of similar triangles
The value of YC is 12 units
<h3>How to determine the length of YC</h3>From the question, we have:
Parallel lines XY || AC
This means that:
BA : BX = YC : BY
Substitute known values in the above ratio
15 : 10 = YC : 8
Express the ratio as fractions
This gives
Multiply both sides by 8
Hence, the value of YC is 12 units

Answer:
And the real value for this case is y=14. The residual is defined as:
Replacing we got:
And the best answer would be:
-2
Step-by-step explanation:
For this case we know that the best fit line for the relationship between x and y is given by:
And we know that an individual in the dataset has a score of 10 on the x-variable and a score of 14 on the y-variable. So then we can find the estimated value like this:
And the real value for this case is y=14. The residual is defined as:
Replacing we got:
And the best answer would be:
-2
Answer:
11 and 12
Step-by-step explanation:
because 11 and 12 are two positive consecutive integers. and when you multiply 11 and 12 you get 132.
