(0,-8)
Explanation: In y=mx + b, m represents the slope of the line and b represents the y intercept, since b is -8, it will cross the y-axis at (0,-8)
Answer:
25 percent
Step-by-step explanation:
Is there a photo? I know the last option is true but I feel like there should be a photo with this
Draw a triangle with shortest side on the ground (horiz.). The length of this side is 80 feet. Two angles touch the ground: a right angle, and the 70 degree angle.
Then the height of the building is the 2nd shortest side.
The tangent function is the appropriate one to use here:
opp h
tan 70 deg = -------- = ----------
adj 80 ft
h
Since tan 70 deg = 2.75, 2.75 = -------
80 ft
so h = building height = (80 ft)(2.75) = 219.8 ft
The binomial cumulative probability with p=0.5 for 3+ successes is as follows:
for p=0.5 (50% success rate) it becomes:
the probability is 0.65625, or about 66%
