425.69+298.72=724.41
29.72+135.47+208.28=373.47
724.41-373.47=350.94
350.94-5=345.94
The answer is c
Answer:
y= -3/4x+3
Step-by-step explanation:
3x+4y=12 first step is to isolate the variable
-3x -3x subtract 3x on both sides
4y=-3x+12
/4 /4 divide both sides by 4
y= -3/4x+3
Answer:
D. Neither group of colleges satisfies her criterion.
Step-by-step explanation:
The probability of admission to at least one of the colleges in the group is the complement of the probability of being admitted to none. That probability is the product of the probabilities of rejection from the colleges in the group.
<u>Group VW</u>
The probabilities of rejection from V and W are 0.6 and 0.75, so the probability of rejection by both is 0.6×0.75 = 0.45. The complement of that, the probability of admission to V or W (or both) is 1 - 0.45 = 0.55, which is less than 60%.
<u>Group XYZ</u>
The probabilities of rejection are 0.7, 0.8, and 0.8, so the probability of rejection by all of X, Y, and Z is 0.7×0.8×0.8 = 0.448. The complement of that, the probability of admission to X, Y, or Z is 1 -0.448 = 0.552, which is less than 60%.
Since neither group of colleges will have a probability of admission of 60% or more, neither group of colleges will satisfy her criterion.
He will be making a right triangle with the legs being 24 x 45. The diagonal will be the hypotenuse of the triangle. To find the amount of fencing we need the perimeter of the triangle.
Use Pythagorean theorem to find the length of the hypotenuse.
a^2 + b^2 = c^2
24^2 + 45^2 = c^2
576 + 2025 = c^2
2601 = c^2
sqrt 2601 = c
c = 51
Adding the three lengths the total fencing needed is
51+24+45=120 meters
