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

Step-by-step explanation:

x=2

y=-3

Answer:

5

Step-by-step explanation:

The x coordinate is always listed first

The coordinate in this ordered pair (5, -8) the X coordinate will be 5.

An ordered pair is made up of the ordinate and abscissa coordinates, with the two values given in parenthesis in a certain order.

Paired in order. Two numbers that must be provided in a specific order are considered ordered pairs. A set of two integers used to locate a point in a coordinate plane is typically referred to as an ordered pair.

The coordinate is given below.

(5, -8)

The y-coordinate is -8 and the x-coordinate is 5.

The ordered pairs are written in a form of (x,y).

Therefore, the ordered pair corresponding to the given coordinates is (-8,9).

Hey there!

“Which expression is equivalent to 6(3x + 4)

6(3x + 4)

6(3x) + 6(4)

6(3x) = 18x

6(4) = 24

= 18x + 24

Possible answer: 18x + 24 ☑️

Answer:

72.5 gallons an hour (i think im sorry if im wrong)

Step-by-step explanation:

Answer: 75%

Step-by-step explanation:

Over the course of seven years, Carrie went from charging the Millards $8 to charging them $14 per hour.

To calculate the percentage increase, use the following formula:

= (New price - Old Price) / Old price * 100%

= (14 - 8) / 8 * 100%

= 6/8 * 100%

= 75%

Carrie's rate went up by 75%.

Answer:

The Correct Answer Is 4

Step-by-step explanation:

So if you have $12 and you can buy $3 with each box of envelopes, you think, how many times can 3 go into 12

count in your head, 3 6 9 12 therefore, ITS 4

here is your equation to match this:

3 x ? = 12

You probably already know this, but i simple way to figure this out is to flip the equation to

12/3 = ?

so from here you can tell that 3 goes into 12 4 times

so the equation is

3 x 4 = 12

Hope It helps!

Answer:

Distance travel by Monica = 628 ft

Step-by-step explanation:

Given:

Radius of whee l = 1 ft

Number of revolution = 100

Find:

Distance travel by Monica

Computation:

Distance travel by Monica = 100[Circumference of wheel]

Distance travel by Monica = 100[2πr]

Distance travel by Monica = 100[2(3.14)(1)]

Distance travel by Monica = 100[6.28]

Distance travel by Monica = 628 ft

Answer:

we have

1+2=180(being co-interior angle)

2x+5+3x-10=180

5x-5=180

5x=180+5

x=185/5=37

m<1=2x+5=2×37+5=74+5=79

Answer:

274878070200

Step-by-step explanation:

4 to the power 11 = 4194304

4 to the power -8 = 0.00001525878

4194304/0.00001525878 = 274878070200

Step-by-step explanation:

x=33 y= -22

52 -33

-22=33m+b

-33=52+b

-11=19m

m=-11/19

-22= 19.105+ b

b= -41.105

y=-11x/19 -41.105

x intercept when y=0

0=-11x/19 -41.105

41.105=-11x/19

-11x= 780.995=781

x= - 71

x-intercept = -71

Answer: x=1, y=-0.5

Answer: the total is 69.24

Step-by-step explanation:

Answer:

s = 17 units

Step-by-step explanation:

In triangle ABD,

(AB)² + (BD)² = (AD)² (by Pythagoras Theorem)

=> 8² + 15² = s²

=> 64 + 225 = s²

=> s = [tex]\sqrt{289}[/tex]

=> s = 17 units

Answer:

simplest form

Step-by-step explanation:

Simplest form is a method of converting the fraction to its lowest multiple.

For example, the fraction 25/100 isn't in its simplest form

Both the numerator and the denominator can be divided by 5. When divided by 5 the fraction becomes 5/20.

5/20 is still not in its simplest form because it can be divided by 5. When divided by 5, the fraction becomes 1/4.

1/4 is now in its simplest form because both the numerator and denominator cannot be divided by any other number

The equation representing the total number of students in the class: b+g=36

The equation representing the total number of boys in the class: b=2g-3

Answer:Time = 1/9 Hours  0r  0.11111 hours

Step-by-step explanation:

We Know that Speed = Distance / Tim\e

Using the constant rate of the speed given as 27 miles per hour at

Distance = 3miles

Time = Distance  / Speed

Time = 3 miles / 27miles per hour = 1/9 hours

Answer:

B 1/3 then reflection across y axis then move figure 2 units to down and 1 right.

Step-by-step explanation:

The figure ABC is bigger than FED so the scale factor is less than one since we are going to ABC to FED. Let look at corresponding sides, AB and FE. AB distance is 3. FE distance is 1 so let divide

[tex] \frac{fe}{ab} [/tex]

[tex] \frac{1}{3} [/tex]

The scale factor is 1/3.

The new points are at A'(-2,0) B'(-2,1) C'(-1,0).

Then we apply reflection.

Since FED is in the 4th quadrant, we are going to reflect across the y axis.

That becomes using formula

(x,y) goes to (-x,y) when reflecting across yaxis.

A''(2,0) B''(2,1) C''(1,0)

Now we will apply the translation. We can simply just move the figure 2 units down and 1 unit to the right.
