Answer:
1512
Step-by-step explanation:
The key is that there's an equal # of boys and girls, 756 each. Add the two together to get 1512
Probability is the study of calculating the chances or likelihood of an event occurring out of the total number of events. This likelihood is always presented as part of a whole. It could be in fractions or percentages.
There are two techniques to apply to this problem. First, we use the repeated trial equation:
P = n!/r!(n-r)! * p^(n-r) * q^r
This is used to determine the probability that an event will occur exactly 'r' times out of 'n' trials. p is the probability of success, while q is the probability of failure. Together, they add up to 1. In this case, each kind of plant has 1/3 probability. So, p=1/3 and q=2/3.
Second thing to note when dealing with probability problems are 'hint words'. When you are asked to find the probability of event A 'AND' event B happening, then you multiply their probabilities. However, when you are asked to find the probability of event A 'OR' event B happening, then you add their probabilities. Hence, the solution to this problem is:
P = 6!/4!(6-4)! * (1/3)^6-4 * (2/3)^4 + 6!/5!(6-5)! * (1/3)^6-5 * (2/3)^5
P = 0.596 or 59.6%
Find the slope of the line first using
(3, 4), (2, -1)
= 5
Now use y - y1 = m(x - x1) to make an equation in slope-intercept form. Plug the numbers into the formula.
y - (-1) = 5(x - 2)
y + 1 = 5x - 10
y = 5x - 11
The equation of the line in slope-intercept form would be y = 5x - 11.
First find the vertical distance from Charlie to the plane by subtracting the altitude of Charlie's eyes from the altitude of the plane: 1700-5.2=1694.8 ft. Let d be the distance from Charlie to the plane. Use the trignometric relationship in the right triangle: sin32=1694.8/d. d=3198 ft.
Solve it in what way, also are those exponents or normal 2’s
