There are six girls and seven boys in the class a team of 10 players is to be selected from the class how many different combina

sweet [91]

Answer:

In 286 different ways 10 players can be selected.

Step-by-step explanation:

There are 6 girls and 7 boys in a class. So in total there are 6+7 = 13 number of students in the class.

A team of 10 players is to be selected from the class.

As there is no other conditions are given, we can pick any 10 students from 13 students.

The way we can select 10 players from 13 students is;

= (13 10)

= 13!/10!(13-10)!

= 13!/10! 3!

= (13 × 12 × 11 × 10!)/ 10! 3!

= ( 13 × 12 × 11)/6

= 286

Step 3: Let LM = x. We know the lengths of the radii of each circle, so KL = 12 +

kow [346]

Answer:

Step-by-step explanation:

Step 3:

Let LM = x

OK = KP = 12 units [Radii of circle K]

LN = LP = 8 units [Radii of circle L]

Therefore, KL = KP + PL

KL = 12 + 8

= 20 units

Step 4:

Since, ΔKOM and ΔLNM are the similar triangles,

By the property of two similar triangles, corresponding sides of these similar triangles will be proportional.

$\frac{OK}{NL}=\frac{KM}{LM}$

$\frac{12}{8}=\frac{x+20}{x}$

12x = 8(x + 20) [By cross multiplication]

12x = 8x + 160

12x - 8x = 160

4x = 160

x = 40

X ^ 2 + 4x - 7 = 0<br><br> Solve using the Quadratic Formula

aalyn [17]

There's a special case of the quadratic formula called the Shakespeare Quadratic Formula (2b or -2b) that applies when the linear coefficient is even.

$x^2-2Bx + C \textrm{ has zeros }x = B \pm\sqrt{B^2 - C}$

If you're planning on solving a lot of quadratic equations quickly, it's good to know.

Here we have

$x^2 + 4x - 7 = 0$

$x = -2 \pm \sqrt{2^2 - -7}$

$x = -2 \pm \sqrt{11}$

Consider all seven-digit numbers that can be created from the digits 0-9 where the first and last digits must be odd and no digi

Yuliya22 [10]

Answer:

1/4 or 0.25

Step-by-step explanation:

The total possibilities of any 7 digit number using 0-9 is :

9×10×10×10×10×10×10=9000000

To work out the total possibilities in this question :

We look at the conditions :

The first digit can only be 5 numbers :

1 , 3 , 5 , 7 , 9

Now we subtract 5 from 9 :

9-5 = 4

Since no repeats for 2 , 3 , 4, 5, 6:

9 , 8 , 7 , 6 , 5,

5 possibilities for the last digit :

Total possibilities for this code :

4 × 9 × 8 × 7 × 6 × 5 × 5 = 302400

If it begins with 5 that is only 1 possibility for the first digit

1 × 9 × 8 × 7 × 6 × 5 × 5 = 75600

Now we make a fraction :

75600÷302400

Dividing top and bottom by 75600 gives you 1/4 or 0.25

Hope this helped and have a good day
