Answer:
1/12
Step-by-step explanation:
The probability of rolling a 4 is 1/6.
The probability of flipping heads is 1/2.
The probability of both is 1/6 × 1/2 = 1/12

Step-by-step explanation:
The perimeter should be 11, since 33 divided by 3 is eleven.
Answer:
2/7
Step-by-step explanation:
Like it says it is the same as monty hall with 3 doors.
You have 7 doors, the probability of the car being in each door is 1/7. After you pick one the probability of the car being in the other doors is 6/7, then he opens 3 doors showing only goats but the probability of it being in one of all the remaining doors is still 6/7 because you made a 1/7 probability choice when you picked your door. Meaning the remaining 3 doors have a probability of 6/7, then 2/7 each
To find the equation for this line, we are going to use point-slope form. First, to find the perpendicular slope, we need to find the slope of the line 4y=5x - 8. To do this, we must transform this equation into slope-intercept form so we can determine the slope.
4y=5x-8
We should divide both sides of the equation by 4 to put the equation into slope-intercept form.
4y/4 = 5x/4 - 8/4
y = 5/4x - 2
Therefore, we can determine that the slope of this equation is 5/4. The slope of the line perpendicular to this line has the opposite reciprocal slope. To find the opposite reciprocal of 5/4, we must make it negative and switch the numerator and the denominator. The opposite reciprocal of 5/4 is -4/5.
Now, we must use this slope and the point we were given, (-5, 4), to write a new equation.
y = m(x-h) + k
y = -4/5(x + 5) + 4
y = -4/5x - 4 + 4
y = -4/5x
Therefore, your answer is y = -4/5x.
Hope this helps!
