Answer:
<em>It would be -7,-2,3,4.</em>
The probability of drawing exactly one red ball is given by:

the probability of drawing two red balls is given by:

The probability of drawing at least one red ball is:
P(1 red ball) + P(2 red balls) = 16/28 + 6/28 = 11/14.
The answer is
Choice given:
<span>33.6°
39.8°
50.2°
56.4°
I drew the figure.
I got 12 ft as the hypotenuse, 10 ft as the opposite.
Sin</span>Θ = opposite / hypotenuse
SinΘ = 10/12
SinΘ = 0.83
I used the calculator to get the value of each angle using the sine function
sin(33.6°) = 0.55
sin(39.8°) = 0.64
sin(50.2°) = 0.77
sin(56.4°) = 0.83
The angle where the wire meets the ground is approximately 56.4°
Answer:
i believe a=105, b=29, and c=45
X + y = 405
y = 8x
To solve:
Plug the second equation into the first and solve for x.
x + 8x = 405
9x = 405
Divide both sides by 9
x = 45
Use the second equation to find y.
y = 8(45)
y = 360
45 angelfish
360 parrotfish
