In order to solve the given expression follow these steps:

1. Take the square roots on both sides in order to get rid of the power on the left side:

√(x-5)² = ±√3

x - 5 = ±√3

2. add 5 on both sides:

x-5 + 5 = 5 ±√3

x = 5 ±√3

Then, the solution is x = 5 ±√3

Determine whether each quadrilateral is a parallelogram. Justify your answer.

Lina20 [59]

Answer:

4. Parallelogram

5. Parallelogram

6. Parallelogram

Step-by-step explanation:

4. This is a parallelogram because the longer sides are parallel to each other and the shorter sides are also parallel to each other. Hence, this is a parallelogram.

5. This is a parallelogram because it's angles are the same to the opposite angles. Hence, this is a parallelogram.

6. This is a parallelogram because the longer sides are parallel to each other and the shorter sides are also parallel to each other. Hence, this is a parallelogram.

the area of a bathroom floor measures 3 yards by 3 yards and each custom tile that makes up the flooring is 1 1/2 square yards.

wel

Using the area, the number of tiles needed to cover the floor is 6.

The area is the region bounded by the shape of an object.

Therefore, the bathroom floor measures 3 yards by 3yards.

Hence the area of the bathroom floor can be calculated as follows;

area of the bathroom floor = 3 × 3

area of the bathroom floor = 9 yards²

The area of the custom tiles that makes the flooring is 1 1 /2 square yards.

Hence,

number of tiles needed to cover the floor = 9 ÷ 3 /2

number of tiles needed to cover the floor = 9 × 2 / 3

number of tiles needed to cover the floor = 18 / 3

number of tiles needed to cover the floor = 6

The question is in the attachment.

Vesna [10]

Answer:

0.0816

Step-by-step explanation:

Given:

Total number of students = 5000
Number of students taking an online class = 1200
Number of students prefer watching baseball to football = 1700

Let O = Students taking an online class

Let B = Students prefer watching baseball to football

Therefore,

P(O) = 1200/5000 = 0.24

P(B) = 1700/5000 = 0.34

If events O and B are independent,

⇒ P(O ∩ B) = P(O) · P(B)

= 0.24 × 0.34

= 0.0816
