A data scientist tracked how many cups of coffee she drank every day at work over the course of a year. She used the data to build a probability distribution where the random variable CCC represents the number of cups of coffee she drank on a given day. Here is the partially completed distribution

Answers

Answer 1

The ommitted distribution :

C : ___ 0 ____ 1 ____ 2 ____ 3

P(C) :_0.05 _ 0.10 _ 0.75 _ 0.10

Answer:

0.19

Step-by-step explanation:

Given the table :

C : ___ 0 ____ 1 ____ 2 ____ 3

P(C) :_0.05 _ 0.10 _ 0.75 _ 0.10

The mean of the distribution is defined as :

ΣX * p(X)

Therefore ;

Σ(C * P(C))

= (0*0.05) + (1*0.10) + (2*0.75) + (3*0.10)

= 0 + 0.10 + 1.50 + 0.30

= 1.90

The mean, also the expected value gives the average number of coffee sold.

Supplementary angles are those which add to 180 o. Complementary angles are those which add to 90°

solve for x
(21x-9)
27
x=​

Answers

Answer:

x = 6

Step-by-step explanation:

∠ AFB and ∠ EFC are vertically opposite angles and are congruent , then

21x - 9 = 117 ( add 9 to both sides )

21x = 126 ( divide both sides by 21 )

x = 6

The measured valued of x is 6.

What are Vertical Angle?

Vertical angles are generated by the junction of two straight lines that are not contiguous. Vertical angles are positioned across from each other in the corners of the "X" created by two straight lines.

We have,

<AFB = 21x- 9

and, <DFC = 27

Using Vertical Angle

<AFB = (<EFD + <DFC)

21x - 9=  (90 + 27)

21x - 9 = 117

21x = 117 + 9

21x = 126

x = 6

John took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4.70 plus $2.50 per mile. The total fare was $24.70, not including the tip. How many miles was the taxi ride? ​

Answers

Answer:

8

Step-by-step explanation:

You can solve this by creating a linear equation.

Slope: 2.50

Y-intercept: 4.70

y=2.50x+4.70

Since we know that the total fare was 24.70 we can plug it into the y.

24.70=2.50x+4.70

Now solve for the equation.

20=2.50x

8=x

So he went 8 miles with the taxi.

Total number or mile taxi run is 8 miles.

Given that;

Pick up charge = $4.7

Charges per mile = $2.5 per mile

Total fare = $24.7

Find:

Number of mile taxi ride

Computation:

Total fare = Pick up charge + [Total number or mile taxi run][Charges per mile]

24.7 = 4.7 + [Total number or mile taxi run][2.5]

[Total number or mile taxi run][2.5] = 24.7 - 4.7

[Total number or mile taxi run][2.5] = 20

Total number or mile taxi run = 20 / 2.5

Total number or mile taxi run = 8 miles

Elise bought a dress that was discounted 35% off of
the original price of $140. What was
a: the amount of discount and
b : the sale price of the dress?

Answers

Answer:

a: $49

b: $91

Explaination:

a: 35% of 140 = 49

b: 140 - 49 = 91

You're welcome! <3

The amount of discount is $49 and  the sale price of the dress is $91 and this can be determined by using the unitary method.

Given :

Elise bought a dress that was discounted 35% off of  the original price of $140.

a) The unitary method can be used in order to determine the amount of discount. If the original price is $140 then the discounted price is given by:

[tex]=\dfrac{35}{100}\times 140[/tex]

Simplify the above expression.

= $49

b) The unitary method can be used in order to determine the sale price of the dress. If the original price is $140 then the selling price is given by:

[tex]=\dfrac{65}{100}\times 140[/tex]

Simplify the above expression.

= $91
