Answer:
x = 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2 from both sides.
Step 3: Divide both sides by -4.
If he flipped the coin 100 times and got 50 heads, then the answer would be 0.5 (since 50/100 = 1/2 = 0.5). I think you might be mixing theoretical probability with empirical probability.
In this case, he got 28 heads out of 75 flips
so 28/75 = 0.373333... where the 3's repeat forever
This rounds to 0.37
That's why the answer is actually choice A
the answer would be -5 and -6.
-5 + -6 = -11 and -5 * -6 = 30 because when multiplying, you cancel out the negative sign when you've got an even amount of negatives.
Answer: y = 
Step-by-step explanation:
The slope intercept form can be written as y = mx + b
Where m is our slope and b is our y-intercept
We're given a slope of 1/2
We're given a y-intercept of -3
Substituting into y = mx + b gives
y = 
Answer:
50.41 feet
Step-by-step explanation:
Hypotenuse = length of ladder
31 = opposite side of angle
sin(angle) = (opposite)/(hypotenuse)
sin(78) = (36)/(hypotenuse)
hypotenuse = sin(78)/ (36)
hypotenuse = 50.41 feet
length of ladder = 50.41 feet
