The total number of subsets that can be derived from the given set is given by the formula 2 n where n is the number of elements present in the set.Here in the given set n=3

Number of subsets = 2 3 = 8 subsets are formed.

Remember, the number of subsets of a set is 2 $2^n$ , where n is the number of elements in the set. Thus, it is 2³ = 8. If you want a proof for that, ask in comments below.

Solve the equation for x, where x is a real number (5 points): <br> -5x^2 + 7x + 41 = 32

wel

Subtract 32 to both sides to the equation becomes -5x^2 + 7x + 9 = 0.

To solve this equation, we can use the quadratic formula. The quadratic formula solves equations of the form ax^2 + bx + c = 0
                   x = [ -b ± √(b^2 - 4ac) ] / (2a)
                   x = [ -7 ± √(7^2 - 4(-5)(9)) ] / ( 2(-5) )
                   x = [ -7 ± √(49 - (-180) ) ] / ( -10 )
                   x = [ -7 ± √(229) ] / ( -10)
                   x = [ -7 ± sqrt(229) ] / ( -10 )
                   x = 7/10 ± -sqrt(229)/10
The answers are 7/10 + sqrt(229)/10 and 7/10 - sqrt(229)/10.

Of all the students that Mikey surveyed, 30% said they play baseball. If 21 students play baseball, how many students did Mikey

Ulleksa [173]

Answer:

70 students

Step-by-step explanation:

As, 30% Mike surveyed

And these 30% are 21 students

So 30% of X = 21

= 30/100 x X = 21

= 30X = 2100
