Answer:

2 + 2i\sqrt{3}

Step-by-step explanation:

note that \sqrt{-1} = i

Given

\sqrt{4} + \sqrt{-12}

= 2 + \sqrt{4(3)(-1)}

= 2 + (\sqrt{4} × \sqrt{3} × \sqrt{-1} )

= 2 + 2i\sqrt{3}

Find the value of x if a, b, and c are collinear points and b is between a and c. ab=x,bc=x 2,ac=14
Aleks04 [339]

The value of x is 7 for the given collinear points a, b, and c as b is the mid-point of ac.

According to the given question.

a, b, and c are collinear points. Which means all points a, b, and c lie in a same plane.

b is lies between a and c.

Also,

ab = x, bc = x and ac = 24.

Since, b lies in between a and c, and it is given that ab = x and bc = x.

Which means b is the mid point of ac.

Therefore,

ab + bc = ac

Substitute the values of ab, bc and ac in the above equation.

⇒ x + x = 14

⇒ 2x = 14

⇒ c = 14/2

⇒ c = 7

Therefore, the value of x is 7.

Suppose that the regression equation y = 16.99 + 0.32 x1 + 0.41 x2 + 5.31 x3 predicts an adult’s height (y) given the individual
umka21 [38]

Answer:

Step-by-step explanation:

It is given that the regression equation

y = 16.99 + 0.32 x_1 + 0.41 x_2 + 5.31 x_3

predicts an adult’s height (y) given the individual’s mother’s height (x1), his or her father’s height (x2), and whether the individual is male (x3 = 1) or female (x3 = 0).

The coefficient of x1 = 0.32 represents the increase in height of the child due to one inch increase in mother.

Similarly coefficient of x2 = 0.42 represents the increase in height of the child due to one inch increase in father.

and coefficient of x3 = 5.31 represents the increase in height of the child due to being a male than a female.

At my favorite computer store, there was a sale of 20% off. I bought a $300
pochemuha
<h2>Answer:</h2><h2>The total cost of the computer = $ 252</h2>

Step-by-step explanation:

The cost of the computer = $300

The sale percentage of the computer = 20%

20% ( 300) =  $60

The current price of the computer = 300 - 60 = $240

5% of salex tax on the computer = 5% (240) = 12

The total price = current price of the computer + sales tax

= 240 + 12

= $252
