Answer:
number one is the appropriate answer for this question
The equation that represents the relationship between x and y is y= 4x.
Answer:
x = 4.
Step-by-step explanation:
We see that it passes through the x axis at the point (4, 0) so x = 4 is a solution.
Check by solving the equation
x^2 - 4x + 13 = 13
Subtract 13 from both sides:
x^2 - 4x = 0
x(x - 4) = 0
x = 0 or x - 4 = 0, so:
x = 0 or 4.
Answer:
14
Step-by-step explanation:
Follow DMAS formula:
DMAS rule is followed when multiple arithmetic operations are there in a given problem like addition, subtraction, multiplication and division. It tells they should be performed in order of Division, Multiplication, Addition and Subtraction.
=50+6*3 -82
=50+18-82
=68-82
=14
Answer:
Step-by-step explanation:
The pdf of X is given by 3e^x(1-e^-2y). Please check the screenshot for the workings.
The pdf of Y is given by 6e^-2y. Please check the screenshot for the workings.
The expected time the device fails is the expected time Y fails, so we are going to find the expected time of Y which equals to 0.83.
