The diagonals of a rectangle are congruent so set them equal to each other to get x = 2x - 7. isolate the variable (0 = x - 7 — x = 7) to get x = 7. the diagonals are seven.
Answer:
88 units squared
The two triangles at the end make it a regular rectangle so you just multiply length by height. Hope this helps!
Step-by-step explanation:
Answer:
P(C|Y) = 0.5.
Step-by-step explanation:
We are given the following table below;
X Y Z Total
A 32 10 28 70
B 6 5 25 36
C 18 15 7 40
Total 56 30 60 146
Now, we have to find the probability of P(C/Y).
As we know that the conditional probability formula of P(A/B) is given by;
P(A/B) =
So, according to our question;
P(C/Y) =
Here, P(Y) =
and P(C
Y) =
{by seeing third row and second column}
Hence, P(C/Y) =
=
= <u>0.5.</u>
