Answer:

Option B. Range of the given sample data is 113.

Step-by-step explanation:

The given question is incomplete; here is the complete question.

Find the range for the given sample data.

The amounts below represent the last twelve transactions made to Juan's checking account. Positive numbers represent deposits and negative numbers represent debits from his account.

$28 -$20 $67 -$22 -$15 $17 -$38 $41 $53 -$13 $30 $75

Option A. $75

Option B. $113

Option C. $37

Option D. -$113

Transaction done by Juan can be arrange from lowest to highest

-38 -22 -20 - 15 -13 17 28 30 41 53 67 75

Now we know rage of the sample data = Highest value - Lowest value

= 75 - (-38)

= 113

Therefore, range of the given sample data is 113.

Option B is the answer.

Answer:

So, ADC = 124/2 => ⛰ ADC = 62°

Step-by-step explanation:

If ABC i.e angle of centra = 124°

If ABC i.e angle of centra = 124°Then, we know that angle at any where of Circle is 1/2 if central angle 

If ABC i.e angle of centra = 124°Then, we know that angle at any where of Circle is 1/2 if central angle So, ADC = 124/2 => ⛰ ADC = 62°.

Solve using quadratic formula 5x^2-4x+3=0

Semenov [28]

Answer:

Impossible

Step-by-step explanation:

In 5x^2-4x+3=0, standard form, substitute these values in the quadratic formula:

a = 5; b = -4; c = 3

The quadratic formula is $x = \frac{ -b ± \sqrt{b^{2} - 4ac}}{2a}$

(ignore the weird capital A)

Substitute a b and c:

$x = \frac{-(-4) ± \sqrt{(-4)^{2} - 4(5)(3)}}{2(5)}$

Simplify:

$x = \frac{4) ± \sqrt{16 - 60}}{10}$

Because $\sqrt{16-60}$ is the square root of a negative number, the answer would be imaginary.

Therefore, there are not solutions to this equation.

A solution is the same as the roots or zeroes, where the graph would cross the x-axis when graphed.

The graph never meets the x-axis. It looks like this:
