OLga [1]3 years ago
5 0

Answer:  Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Total students in a class = 30

Number of students is to be chosen = 4

So, we will use Combination :

<u>As Combination is the collection of the object irrespective of any arrangement.</u>

So, Number of ways to choose 4 students among the 30 students is given by

^{30}C_4\\\\=27405

Hence, Combination is the required answer.

Therefore, Option 'A' is correct.

For what value of the variable will the expression 8b−27 be equal to the following:<br> 5
qaws [65]

Answer:

We need to find the value of b to make 8b - 27 be equal to 5, so:

8b - 27 = 5

We solve the equation:

8b = 5 + 27

8b = 32

We divide both sides by 8:

b = 32/8 = 4

So now, we know that b=4, and we can verify:

8*4 - 27 = 5

32 - 27 = 5 TRUE

Could someone pls send me an example of using the substitution method in algebra?
Elden [556K]

Answer:

in this method a variable is expressed in terms of another variable from one equation and it is substituted in remaining equation.

Step-by-step explanation:

solve:x+2y=9 and 3x-y=13.

x+ 2y=9…be the first equation

3x-y=13…be the second equation

from first equation

x=9-2y…be the third equation substituting value of x from third equation in second equation, we get

3(9-2y)-y=13

or, 27-6y-y=13

or, y=2

now,

substituting value of y in third equation, we get,

x=9-2×2

=9-4

=5

the required value of x and y are 5&2
