Please help, im so confused PLEASEEEEE

Answer:

291.63 ml

Step-by-step explanation:

200/72 2.7778 half lives

(1/2)^2.77777 =   .1458        or    291.63 ml

Using the stated percentage, it is determined that it has a 0.877 = 87.7% chance of arriving on time.

The number of desired outcomes divided by the total number of outcomes yields a probability.

A percentage can be regarded as a probability over a big sample.

In this question, 87.7% of flights arrive on time in Atlanta, based on a significant number of flights. As a result, there is a 0.877 = 87.7% chance that it will arrive on time.

Answer: 86.1%

Answer:

Pasos para resolver una ecuación lineal

3x−2/4−2x+5/3=1−x/6

Multiplique ambos lados de la ecuación por 12, el mínimo común denominador de 4,3,6.

36x−3×2−24x+20=12−2x

Multiplica −3 y 2 para obtener −6.

36x−6−24x+20=12−2x

Combina 36x y −24x para obtener 12x.

12x−6+20=12−2x

Suma −6 y 20 para obtener 14.

12x+14=12−2x

Agrega 2x a ambos lados.

12x+14+2x=12

Combina 12x y 2x para obtener 14x.

14x+14=12

Resta 14 en los dos lados.

14x=12−14

Resta 14 de 12 para obtener −2.

14x=−2

Divide los dos lados por 14.

Answer: 45

Step-by-step explanation:

I had the same problem it's 45. 45 is the maximum or greatest data in the box plot.

Answer:

C(50;-20)

Step-by-step explanation:

The question is asking for the midpoint of the line.

The triangle is formed by placing a line directly from the y-axis to the x-axis.

The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].

your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.

Your coordinates for B are (100;0)

C[(x1+x2)/2 ; (y1+y2)/2 ]

C [(0+100)/2 ; (-40+0)/2 ]

C[ 100/2 ; -40/2]

C (50 ; -20)

Answer:

(-4, 1) is the coords of the final point

Step-by-step explanation:

First do the translation: (3,1) to the right 1 unit is (4,1).
Now the reflection: (4,1) reflected over the y-axis is (-4, 1)

this should be correct... please tell me if its not! hope this helps!!

Answer:

72 ft ^2

Step-by-step explanation:

Surface area =  2 * ( 3x6   + 6x2  + 2x3)  = 72 ft^2

Answer: = x > $124.3

Step-by-step explanation:

Alicia's Paycheck = x

Took half money for dinner x/2

She spent $42.15 on dinner and she brought home more than $20.00

.x/2 - $42.15  > $20.00

 => x/2 > $62.15

=> x > $124.3

I hope that helps! Have a great day!!

Answer:

Step-by-step explanation:

Haven't done this in awhile but I think it's 2 because if you cube 2 it comes to 8. L x W x H = 8 | 2 x 2 x 2 = 8

Answer:

y = 3x - 3

Step-by-step explanation:

Given, (2,3) and (-1,9), m = 3

Equation of a straight line is y = mx + c

Here, y = 3, x = 2 and m = 3

Substituting the values in y = mx + c we get,

3 = 3(2) + c

c + 6 = 3

c = 3 - 6

c = -3

So, the equation of the line is y = 3x - 3  (Answer).

Answer:

5 - 55

6 - 125

7 - 55

8 - 125

Step-by-step explanation:

6 is 125 because of alternate interior angles.

8 is 125 because of vertical angles

5 is 55 because of supplementary angles

8 is 55 because of vertical angles (to 5)

b= 2 and 5

is your answer to the above question.

Answer:

s = [tex]\frac{19}{4}[/tex]

Step-by-step explanation:

substitute the given values into the equation

s = (10 × [tex]\frac{1}{2}[/tex] ) + ( [tex]\frac{1}{2}[/tex] × - 2 × ([tex]\frac{1}{2}[/tex] )² )

  = 5 + (- 1 × [tex]\frac{1}{4}[/tex] )

  = 5 - [tex]\frac{1}{4}[/tex]

  = 4 [tex]\frac{3}{4}[/tex]

  = [tex]\frac{19}{4}[/tex]

Answer:

See below

Step-by-step explanation:

Arrange the list in ascending order

16 800   18400    19 950    23 400    26 500    47 800

MEDIAN is the middle number ...since there are TWO in the middle it is the average of the two    (19950 + 23400) /2 = 21675

MEAN is the average...add all of the numbers and divide by 6

   = 25475

Answer:

a) 2a

b) -a + b

c) -b -a

Step-by-step explanation:

a) From C, you just go down with a twice.

b) From A, you go up the a hence -a, then you go down b so -a + b.

c) From B, you go down b to O then you go up a to C.

Step-by-step explanation:

Answer:

84

Step-by-step explanation:

198 × 50%

198 × 50/100

198 × 1/2

198/2=84

Answer:6 dollars

Step-by-step explanation:5 +20% gives you 6 which would be the ending price

[tex]3x + x - 4 + 100 = 180[/tex]

[tex]4x + 96 = 180[/tex]

[tex]4x = 180 - 96[/tex]

[tex]4x = 84[/tex]

[tex] \frac{4x}{4} = \frac{84}{4} [/tex]

[tex]x = 21[/tex]
