Answer:

There are 3 elements in the set.

Step-by-step explanation:

Given set,

{A, B, C}

∵ Set is the collection of defined distinct objects,

These objects are called elements of the set,

We have given a set in which A, B, C are present thus they must be distinct,

So, by the above definition,

The given set has three elements.

Answer:

The maximum variance is 250.

Step-by-step explanation:

Consider the provided function.

$V(x)=1000x(1-x)$

$V(x)=1000x-1000x^2$

Differentiate the above function as shown:

$V'(x)=1000-2000x$

The double derivative of the provided function is:

$V''(x)=-2000$

To find maximum variance set first derivative equal to 0.

$1000-2000x=0$

$x=\frac{1}{2}$

The double derivative of the function at $x=\frac{1}{2}$ is less than 0.

Therefore, $x=\frac{1}{2}$ is a point of maximum.

Thus the maximum variance is:

$V(x)=1000(\frac{1}{2})-1000{\frac{1}{2}}^2$

$V(x)=250$

Hence, the maximum variance is 250.

MARK AS BRAINLEST! 5 + x = 5

n200080 [17]

Answer:

x = 0

Step-by-step explanation:

You know the answer to this because you know the identity element for addition is 0: 5 + 0 = 5.

Or, you can make use of the addition property of equality and add -5 to both sides of the equation:

5 - 5 + x = 5 - 5

x = 0 . . . . . . . . . . simplify

Answer:

Step-by-step explanation:

Formula

$B = 25(\frac{M}{10} +\frac{3}{4} )$

Where M meters of granola makes B granola bars.

Given:

M = 2.5 meters

Now substitute that value in the formula and calculate.

$B=25(\frac{2.5}{10} +\frac{3}{4} )= 25(1) = 25$

Therefore, 2.5 meters of granola makes 25 granola bars.

B = 25

7(x-4)=14 what are the steps?

Vaselesa [24]

Answer:

x=6

Step-by-step explanation:

multiply 7 by x and 7 by -4. You get 7x-28=14, add 28 to 14, which is 42. So 7x=42, then divide 7 on both sides, and you get x=6.
