Answer: −1.409
Step-by-step explanation:
Probability of drawing 3 hearts: 13/52 * 12/51 * 11/50 = 0.013
Probability of drawing 3 black cards: 26/52 * 25/51 * 24/50 = 0.118
Probability of other draw: 1 - 0.013 - 0.118 = 0.869
0.013 * (50 - 5) = 0.585
0.118 * (25 - 5) = 2.353
0.869 * (0 - 5) = -4.347
Expected value: 0.585+ 2.353 - 4.347 = -1.409
I believe A, D, and E are the correct answers.
I don't think the title of a line graph is completely necessary, as long as the viewers know what the graph is showing.
Also, color is not important if you only have 1 line. If you have multiple lines though, then you would probably need color.
But it is extremely necessary to have equal intervals on your graph, otherwise it just won't make sense.
Also, if you don't have an X axis or a Y axis, then half of your graph is missing!
I'm not sure if it's as necessary to have a grid, but the graph might be hard to read without it. So, I would put that down as an answer.
Answer:122
Step-by-step explanation:
The answer is D
Explanation:5x^5-44x^3-9x=0
X(5x^2+1)(x-3)(x+3)=0
X(x+3)(x-3)=0
X=0,x=-3,x=3
Answer:
1884 flowers
Step-by-step explanation:
Radius of the garden=150 ft
To determine the number of flowers needed to surround the circular garden, we first find the perimeter.
Since the flowers are spaced every 6 in, we need to convert from inch to feet because we cannot divide different units.
Now, 12 Inch =1 Feet
Therefore, 6 Inch =0.5 feet
To determine the number of flowers, we simply divide the perimeter by 0.5 ft.
Number of flowers=942/0.5
=1884 flowers
