Answer:

.753

Step-by-step explanation:

Let Ps = probability both marbles are the same color.

Let Pd = probability both marbles are a different color.

Pd = 1 -Ps

Let Pb = probability both marbles are blue

Let Pr = probability both marbles are red.

Let Pg = probability both marbles are green

Pb= 2/9 * 1/9 = 2/81

Pr= 4/9 * 3/9 = 12/81

Pg=.3/9 * 2/9= 6/81

Ps = Pb + Pr +Pg= 20/81

Pd =1-Ps= 61/81 = .753

Is this correct?

Answer:

x = 30

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

The given is a right triangle so one of the angle is 90 degrees:

90 + 2x + x = 180 add like terms

90 + 3x = 180 subtract 90 from both sides

3x = 90 divide both sides by 3

x = 30

We know that:

We know that, 1 litre = 1000 ml

Then, 2 litres = 2000 ml

Hence, the required ratio of 1000 ml to 2000 ml be

= 1000 : 2000

= 1 : 2

1 litres =1000ml

then

1000:2000

Answer:

  (1/2)^(t/4) = ((1/2)^(1/4))^t

Step-by-step explanation:

If time t is given in hours, then the number of 4-hour time periods is t/4. If the half-life is 4 hours, the population multiplier is ...

  (1/2)^(t/4)

Using the rules of exponents, that can be rearranged to ...

  (1/2)^((1/4)·t) = ((1/2)^(1/4))^t

That is, the multiplier every hour is ...

  (1/2)^(1/4)

_____

The relevant rule of exponents is ...

  (a^b)^c = a^(bc)

Answer:

53.7

Step-by-step explanation:

Rectangle: lenth = 14, width = 2 * 5 = 10

perimeter of reactangle (3 sides) = 14 + 10 + 14 = 38

perimeter of semicircle = π * 5 = 3.14 * 5 = 15.7

Total perimeter = 38 + 15.7 = 53.7

Answer:

Step-by-step explanation:

Rectangle:

Length = 14 units

Width = diameter of the semicircle = 2*5 = 10 units

Circumference  of circle = πr = 3.14 * 5 = 15.7 units

Perimeter of the figure = 14 + 10 + 14 + 15.7 = 53.7 units

Answer:

1/4

Step-by-step explanation:

First we need to find the total of the fruit

7+5+8 = 20

The fraction of the fruit that is mangoes is the number of mangoes over the total.

mangoes / total = 5/20 = 1/4

=======================================================

Explanation:

Line K is 9x-4y=-5*4 which is the same as 9x-4y=-20

Rule: Anything parallel to Ax+By = C is of the form Ax+By = D.

The equation 9x-4y=-20 has A = 9, B = -4 and C = -20.

That means Ax+By = D becomes 9x-4y = D.

------------------------------

Plug in the coordinates (x,y) = (4,7) and compute the value of D.

9x-4y = D

D = 9x-4y

D = 9(4)-4(7)

D = 36 - 28

D = 8

So 9x-4y = D becomes 9x-4y = 8

----------------------------

The last step is to solve for y to get the equation in y = mx+b form.

9x-4y = 8

-4y = 8-9x

-4y = -9x+8

y = (-9x+8)/(-4)

y = (-9x)/(-4) + 8/(-4)

y = (9/4)x - 2    is the slope-intercept form of line L

The equation is in y = mx+b form where,

m = 9/4 = slope

b = -2 = y intercept

Answer:

segment

Step-by-step explanation:

a line goes on forever in both directions

a point has no length

a ray starts on a point and continues forever in one direction

a segment has a beginning and end because it starts on a point and ends on a point

Step-by-step explanation:

Answer:

3rd option

Step-by-step explanation:

always choose the equation where the variable is alone.

second equation has a lone 'y' and all that needs to be done is subtracting 2x from both sides of equal sign.

Answer:

a = 7

Step-by-step explanation:

Using the Cosine rule in the triangle

a² = b² + c² - (2bc cosA )

   = 2² + (5[tex]\sqrt{3}[/tex] )² - (2 × 2 × 5[tex]\sqrt{3}[/tex] × cos30° )

  = 4 + 75 - (20[tex]\sqrt{3}[/tex] × [tex]\frac{\sqrt{3} }{2}[/tex] ) ← exact value of cos30°

 = 79 - ( 10 × 3)

 = 79 - 30

 = 49 ( take square root of both sides )

a = [tex]\sqrt{49}[/tex] = 7

Answer:

a = 7

Step-by-step explanation:

a² = b² + c² - 2bc × cos α

a² = 2² + ( 5√3 )² - 2 × 2 × 5√3 × [tex]\frac{\sqrt{3} }{2}[/tex]

a² = 49

a = 7

Answer:

1

Step-by-step explanation:

Mistake in the second step.

We must add positive numbers or negative ones.

Here he had add the positive and negative numbers and that is the mistake

[tex]=3-(-5)-7\\\\=3+5-7[/tex]Here 5 is positive because -×-=+

[tex]=8-7[/tex]

[tex]=1[/tex]

In the second step, we must add the positives that are 3 and 5 and subtract from 7.

The expected number of times he picks a blue marble is the mean of the blue marbles

Malik should expect to pick a blue marble 10 times when he picks 25 marbles

The given parameters are:

Blue = 16

Red = 12

Green = 12

The total number of marbles is:

Total = 16 + 12 + 12

So, we have:

Total = 40

When he picks 25 marbles, the expected number of blue marble is:

Expected = Blue/Total * 25

So, we have:

Expected = 16/40 * 25

Evaluate the product

Expected = 10

Hence, he should expect to pick a blue marble 10 times when he picks 25 marbles

Answer:

Option D

Step-by-step explanation:

Given the following question:

Airline makes $98,410
Truck driver makes $38,200

Annually means in a year so the airline makes $98,410 and the truck driver makes $38,200 in a year.

Now in order to find the amount the two make in 20 years we have to multiply:

[tex]98410\times20=1968200[/tex]
[tex]38200\times20=764000[/tex]

Now since the question asks "how much MORE" does the airline make we have to subtract:

[tex]1968200-764000=1204200[/tex]
[tex]=1204200[/tex]

The airline makes "$1,204,200 more dollars" than the truck driver, or option D.

Hope this helps.

Answer:

The answer is either D or B

Step-by-step explanation:

98,410 x 20 is 1,968,200 so

it might be closer to D or B instead.
