Answer:
y = ± 12
Step-by-step explanation:
Given
y : 24 = 6 : y, or in fraction form
= 
( cross- multiply )
y² = 144 ( take the square root of both sides )
y = ± 
= ± 12
Answer:
C. f⁻¹(x) = 3 - 5x
Step-by-step explanation:
To find the inverse of a function, switch x and y and solve for y.
f(x) = (3 - x)/5
Change f(x) to y.
y = (3 - x)/5
Switch x and y.
x = (3 - y)/5
Multiply both sides by 5.
5x = 3 - y
Subtract 3 from both sides.
5x - 3 = -y
Multiply both sides by -1.
-5x + 3 = y
Switch the sides.
y = -5x + 3
Change the equation.
y = 3 - 5x
Answer:
w = 52°
Step-by-step explanation:
We know that the sum of the angle of a triangle is equal to 180 degrees
In this figure,
w+w+76 = 180
As w = w (Vertically opposite angles)
So,
2w = 180-76
2w = 104
w = 52
So, the value of w is equal to 52°.
Answer:
A. What happens on one trial affects the probability on the next: they are dependent events.
Step-by-step explanation:
Below are some important characteristic of a binomial experiment:-
- A binomial experiment has n trials.
- Each trials has two possible outcomes. Success or failure.
- The probability of success is same in very trail.
- The event is independent event. In other words, the probability of one event doesn't effect the other.
- The coefficient of the binomial term can be determined using Pascal’s triangle
Basis these characteristics, only the first option is not a properties of a binomial experiment. In case of binomial experiment, the event is independent event.
Hence, option A is correct.
The data is skewed to the right so the mean will be higher than the median. The median would be a better picture of the data.
