Answer:
B. x = 7, y = 4√2
Step-by-step explanation:
Drop a vertical from the upper left corner
This creates a rectangle and a 45-45-90 triangle
The bottom of the rectangle is 3
The legs of the triangle are 4
Therefor
x = 4 + 3
x = 7
For a 45-45-90 triangle
the hypotenuse = leg * √2
y = 4√2
The slope, or gradient, of the line is 6/-3 which is -2. The gradient is -2.
Answer:
System A is A System B is B
Step-by-step explanation:
Probability of Quiz = 0.6
Probability of Not doing homework 0.85
Probability of both event happening = P1 * P2 = 0.51
The probability of there being a quiz and you not doing the homework is 51%
