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?

Solve for r.
–6(r − 98) = 78
Answers
Answer:
r = 85
Step-by-step explanation:
→ -6 ( r - 98 ) = 78→ r - 98 = -13→ r = -13 + 98→ r = 85conclusion:
so the value of r is 85
Step-by-step explanation:
First, divide both sides of the equation by -6.
-6(r-98)÷6=78÷6
This gives us r-98=-13
Then, add 98 to both sides.
r-98+98=-13+98
The answer is r=85

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.

Factor the trinomial
Answers
Answer:
3x (x-3)
Step-by-step explanation
3x^2 - 9x + 0
The equation.
3x^2 - 3^2 × x
What I did here is that I factored out 9x to 3^2 times x.
3x (3x^2 all over 3x - 3^2 × x/ all over 3x)
So that way I can divide the number in the parentheses by 3x to take 3x out of the parentheses to factor out.
3x (x^2-1 - (3^2-1) )
You simplify to get the final answer.
3x (x-3)
Final Answer.

Mark took his family to the movies and spent a total of 78$ on tickets he also bought a soda for each family member each sodas cost 4.25 if mark spent a total of 102,50 on sodas and tickets. How much sodas did he buy
Answers
Answer: He bought about 6 sodas.
Step-by-step explanation:
Given: Tota cost of tickets = $ 78
Cost of each soda = $4.25
Total cost of sodas and tickets = 102.50
Let x = Number of sodas purchased
Then
[tex]78+4.25x=102.50\\\\\Rightarrow\ 4.25x=102.50-78\\\\\Rightarrow\ 4.25x=24.5\\\\\Rightarrow\ x= \dfrac{24.5}{4.25}\\\\\Rightarrow\ x\approx6[/tex]
Hence, he bought about 6 sodas.
