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

Caleb is driving on a long road trip, He currently has 11 gallons of gas in his car, Pach
hour that he drives, his car uses up 2 gallons of gas, How much gas would be in the
tank after driving for 4 hours? How much gas would be left after t hours?
Answer:
4 hours = 3
t hours = 11-2t
Step-by-step explanation:
11 gallons = total
2 gallons are used up per hour
So:
11 - 2 * ( number of hours) = number of gallons
11 - (2 * 4) = 11 - 8 = 3
11 - (2t)
Answer:
3 gas
Step-by-step explanation:
4x2=8

15 to 19 is 4
19 is the larger than 15 so since 19 is negative your answer will also be negative
parallelogram
b= 13 ft. 6 in.
h= 10 ft. 3 in.
Answer:
A=19,926in.
or
A=1660.5ft
Step-by-step explanation:
you convert the feet into inches which gives you a base of 162 inches and a height of 123 inches. Next you multiply your base and height and it gives you an Area of 19,926inches but then if you need to convert the inches back into feet by dividing 19,926 by 12. After you do that you should end up with an area of 1660.5 feet.

Can you guys figure out the linear function for this table, please?
Answer:
y = 6x + 10
Step-by-step explanation:
This is because the slope is 6 and the y intercept is 10, therefore the answer is y = 6x + 10
The membership in the Lego Club decreased from 120 members in August to 82 members in October. What was the percent decrease from August to October?
Type your answer using the % key. Round to the nearest whole percentage if necessary.
Answer:
72% decrease I...guess?
120 members-60 members=50%
-70 should be approx=60%
-80 should be approx=70%
so 80 is around 70%, so I'd say 82 is 72%
I'm most likely wrong but i dunno maybe im right
Step-by-step explanation:
Answer:
32%
Step-by-step explanation:
((120 - 82) / 120) x 100 = 31.66 %
31.66% to the nearest whole percentage is 32%

Step-by-step explanation:
-2(4x-1)-7=5
whats the next step in solving this equation
Answer:
Using distributive property is the next step in solving the equation
Step-by-step explanation:
-2(4x-1)-7=5
-8x+2-7=5
Answer:
The next step would be to do distributive property.
Step-by-step explanation:
-2(4x-1)-7=5
-8x + 2 - 7 = 5
-8x - 5 = 5
+5 +5
-8x = 10
/-8 /-8
x= -5/4
or
x = -1 1/4

A certain forest covers an area of 4800 km^2 . Suppose that each year this area decreases by 5.25% . What will the area be after 6 years? Use the calculator provided and round your answer to the nearest square kilometer.
Answer:
the area after 6 years is 3,473 km^2
Step-by-step explanation:
The computation of the area after 6 years is as follows:
= Area × (1 - decreased percentage)^number of years
= 4,800 km^2 × (1 - 5.25%)^6
= 4,800 km^2 × 0.9475^6
= 3,473 km^2
Hence, the area after 6 years is 3,473 km^2
