Solving Quadratic Equations by completing the square<br><br> xz^2 - 3z - 5 =0

Andrei [34K]

Answer:

x=3z+5

/z^2

Step-by-step explanation:

Let's solve for x.

xz^2−3z−5=0

Step 1: Add 5 to both sides.

xz^2−3z−5+5=0+5

xz^2−3z=5

Step 2: Add 3z to both sides.

xz^2−3z+3z=5+3z

xz^2=3z+5

Step 3: Divide both sides by z^2.

xz^2

The figure shows segment A D with two points B and C on it in order from left to right. The length of segment A B is 22 units, t

valentina_108 [34]

The total length of the segment AD will be 52 units.

The complete question is given below:-

The figure shows segment A D with two points B and C on it in order from left to right. The length of segment A B is 22 units, the length of segment BC is 19 units, and the length of segment C D is 11 units. What will be the total length of the segment AD?

<h3>What is the length?</h3>

The measure of the size of any object or the distance between the two endpoints will be termed the length. In the question the total length is AD.

Given that:-

Segment AD with two points B and C on it in order from left to right.
The length of segment AB is 22 units, the length of segment BC is 19 units, and the length of segment C D is 11 units.

The total length will be calculated as:-

The total length will be equal to the sum of all the segments of line AD. It will be the sum of AB, BC and CD.

AD = AB + BC + CD

AD = 22 + 19 + 11

AD = 52 units

Therefore the total length of the segment AD will be 52 units.

A bag contains tickets numbered 1 through 5. Use the probability distribution to determine the probability of drawing an odd num

Makovka662 [10]

Answer:

The probability of drawing an odd numbered ticket is 60%.

Step-by-step explanation:

Odd numbered tickets:

Probability of one is 1/5 plus half of 1/5.

$P(X = 1) = \frac{1}{5} + \frac{1}{10} = \frac{3}{10}$

Probability of 3 is half of 1/5.

$P(X = 3) = \frac{1}{10}$

Probability of 5 is 1/5. So

$P(X = 5) = \frac{1}{5}$

Probability of drawing an odd numbered ticket:

$p = P(X = 1) + P(X = 3) + P(X = 5) = \frac{3}{10} + \frac{1}{10} + \frac{1}{5} = \frac{4}{10} + \frac{2}{10} = \frac{6}{10} = 0.6$

0.6*100% = 60%

The probability of drawing an odd numbered ticket is 60%.
