A box contain 10 green pins 3 are blue and 7 are green. Two pins are randomly taken out of the box without replacement work out the probability that both pins are the same color

Answers

Answer 1

Answer:

[tex]P(Z)=\frac{8}{15}[/tex]

Step-by-step explanation:

From the question we are told that:

Sample size [tex]n=10[/tex]

Green pins [tex]x=7[/tex]

Blue pins [tex]y=3[/tex]

 

Generally the probability of getting two green is mathematically given by

[tex]P(2X)=\frac{7}{10}*\frac{6}{9}[/tex]

[tex]P(2X)=\frac{7}{15}[/tex]

Generally the probability of getting two blue is mathematically given by

[tex]P(2Y)=\frac{3}{10}*\frac{2}{9}[/tex]

[tex]P(2Y)=\frac{1}{15}[/tex]

Therefore the probability that both pins are the same color P(Z)

[tex]P(Z)=P(2Y)+P(2X)\\P(Z)=\frac{7}{15}+\frac{1}{15}[/tex]

[tex]P(Z)=\frac{8}{15}[/tex]

find the volume of the composite figure​

Answers

39in³ is a required volume.

Solution given:

for upper one

length[l]=8in

breadth[b] =3in

height[h]=1in

now

volume [V1]=l×b×h=8×3×1=24in³

again for lower one:

length[l]=6-1=5in

breadth[b] =3in

height[h]=1in

volume [V2]=l×b×h=5×3×1=15in³

Again

total volume =V1+V2=24in³+15in³=39in³

Which of the following correctly isolates the constant for the polynomial: x2 – 12x + 27

A. x^2 – 12x = 27
B. x^2 - 12x = 36
C. x^2 - 12x = -27
D. x^2 + 27 = 12x

Answers

Answer:

x^2 - 12x = -27

Step-by-step explanation:

Here, we want to isolate the constant for the polynomial

To do this, we start by setting the expression to zero

Afterwards, we can bring the constant term over the equal to sign, giving a change in sign value

Mathematically, we have this as;

x^2 - 12x + 27 = 0

x^2 - 12x = -27

the volume of a sphere is 4851 cubic cm find its diameter​

Answers

Answer:

The diameter is 21 cm

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3)πr³, or (in terms of the diameter)  V = (4/3)π(d/2)³.  This simplifies to

       4πd³          πd³

V = ----------- = -----------

        3·8               6

Now equate V = (πd³/6) to 4851 cm³.  We must first solve this for d³ and then take the cube root of the result:

πd³ = 4851(6) = 29106.

Dividing this result by π yields 9264.7,

and taking the cube root of this is 21.  The diameter is 21 cm
