She stopped because:
| 2 x - 0.6 | ≠ -2 . It is absolute value and it can´t be equal to the negative number.
This equation has no solution.

A list has 10 numbers. Each number is a 1, 2, or 3. The average is 2 and the SD is 0. What is the list?

OLga [1]

Answer:

1, 1, 1, 2, 2, 2, 2, 3, 3, 3

Step-by-step explanation:

Since the standard deviation = 0

And the mean of the number = 2

If X is the sum of all the numbers, then

X/10 = 2

Cross multiply and make X the subject of formula

X = 2 × 10 = 20

The sum of the numbers will be 20

The number will be

1, 1, 1, 2, 2, 2, 2, 3, 3, 3

The sum of the above numbers is equal to 20 and the average value of the numbers is equal to 2.

When using the given diagram, the following steps prove the Pythagorean theorem. Step 1: Given yellow triangle abc Step 2: Const

Keith_Richards [23]

Answer:

B. $\dfrac{1}{2}ab$

Step-by-step explanation:

Given the proof below:

<u>Proof of Pythagorean theorem.</u>

Step 1: Given yellow triangle abc

Step 2: Construct 3 triangles congruent to yellow triangle abc.

Step 3: $(a + b)^2 = c^2 + 4(\dfrac{1}{2}ab)$

Step 4: $a^2 + 2ab + b^2 = c^2 + 2ab$

Step 5: $a^2 + b^2 = c^2$

Since Area of a Triangle = $\frac{1}{2}X$Base X Height$

The expression that represents the area of each triangle is <u>Option B.</u>
