What are all the possible rational solutions for x^4-3x^2+2x5=0
Answer: x = 1
x =(-3-√-15)/4=(-3-i√ 15 )/4= -0.7500-0.9682i
x =(-3+√-15)/4=(-3+i√ 15 )/4= -0.7500+0.9682i
x2 = 0
Step-by-step explanation:
A construction company submitted bids for three contracts. The company estimates that it has a 20%
chance of winning any given bid. Let X represent the number of bids the company wins. Here is the
probability distribution of X along with summary statistics:
X = # of bids won-
0 1 2 3
P(X)-
0.512 0.384 0.096 0.008
Mean: µx=0.6
Standard deviation: σx=0.69
It costs the company a total of $2,000 to submit these bids, and they stand to gain $10,000 for each bid
they win. Let V represent their net gain from submitting these three bids.
What are the mean and standard deviation of V?
µv= ______dollars
σv=_______dollars
Answer: 4000 dollars
6900 dollars

So your answer is 15
Plz help me :(:(:(:(:(:(:(:(::(((::(:(:(.(.(
Answer:
Look below!
Step-by-step explanation:
Angle A = 180-47 = 133
Angle B = 180-32-Angle A = 180-32-47 = 101
Angle D = 90-32 = 58
Angle C = 180-47-58 = 75
Hope I helped!
Answer:
A=133 ,B=15, C=75 D= 58
Step-by-step explanation:
Angle 32, d, and right angle add up to 180. So 180=32+90+x. Then x = 58 (D). The all 3 angles in the triangle add up too 180 so 180=47+58+x. x=75 (C). The 47 and a equal to 180 degrees. 180-47=133. The 133+32+x=180. x=15 (B).

Anais bought 4 1/2 yards of ribbon. She had 3 feet 8 inches of ribbon left after trimming some curtains. How many inches of ribbon did anais use to trim the curtains
Answer:
First convert all numbers into inches since that is the answer being solved for.
1 yard =36 inches
4.5 x 36 = 1,620 inches
1 foot = 12 inches
3 x 12 = 36 inches
36 + 8 = 44 inches
Now take 1,620 inches (starting ribbon measure) and subtract 44 inches (what was left over) to get the inches used to trim curtains.
1,620 inches - 44inches =
1,576 inches were used to trim the curtains.

The graph which represents the function; y = 2 x - 2 is the second graph from the left.
Graph of FunctionsBy considering the slope-intercept form of the equation of a straight line;
y = mx + cBy observation, the graph of the function has y-intercept, -2 and has slope, m = 2
The graph most comparable to the information above is the third graph and hence is the graph of the function.

There are 8 students on the school chess team. They need to raise at least $760 for a field trip. Their advisor says they still need to raise 85% of the funds, and she wants each of them to raise an equal share of the money still needed. Diego wrote and solved the inequality 8m + 0.85(760) ≥ 760 to find the least amount of money, m, each student on the chess team needs to raise. He says the solution is m ≥ $14.25. Diego is incorrect.

please help solve for x ................................................................
Answer:
104°+33°+(5x+13)°=180°[all angle sum is 180°]
137°+(5x+13)=180°
137°+13+5x=180°
150°+5x=180°
5x=180°-150°
5x=30
x=30/5
×=6
Answer:
x = 6
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
5x + 13 + 104 + 33 = 180, that is
5x + 150 = 180 ( subtract 150 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6
