(a + b)^2

You are given that a = 2 and b = 3, so plug in 2 for a and 3 for b in the expression.

Now your expression should look like this:

(2 + 3)^2

Solve within the parentheses first.

(5)^2

Square 5.

(5)^2 = 25

Your answer to this problem is 25.

A 2-liter container holds more than a 3,000-milliliter container. True or false?
tiny-mole [99]

<u>To consider whether this statement is true or not</u>

   ⇒ must determine the <u>number of milliliters in a liter</u>

        ⇒ <u>1 Liter = 1000 milliliter</u>

<u />

<u>To compare both containers, lets set both containers in terms of milliliters</u>

  • Container 1 --> 2 Liter Capacity --> 2000 milliliter
  • Container 2 --> 3000 milliliter

<u>By looking at the data</u>

  ⇒ the 3000-milliliter container holds more than the2-liter container

<u>Thus, the statement</u>: A 2-liter container holds more than a 3,000-milliliter container

  ⇒ <u>False</u>

<u></u>

<u>Answer: False</u>

A population of small bottles and their contents has the following weights (in grams): 4, 2, 5, 4, 5, 2, and 6. What is the vari
Ahat [919]

Answer:

D. 2.33.

Step-by-step explanation:

Given;

the weight distribution of the bottles = 4, 2, 5, 4, 5, 2, and 6

sum of the weights = 28

the mean (x) = 28/7

                 x = 4

the sum of square of the mean deviation is calculated as:

= (4 - 4)² + (2 - 4)² + (5 - 4)² + (4 - 4)² + (5 - 4)² + (2 - 4)² + (6 - 4)²

= 0 + 4 + 1 + 0 + 1  + 4 + 4

= 14

the \ variance \ is \ calculated \ as:\\\\\sigma ^2 = \frac{\sum (x-\bar x)^2}{n-1} \\\\\sigma ^2 = \frac{14}{7-1} = \frac{14}{6} = 2.33

Therefore, the correct answer is D

const2013 [10]

Answer:

<em>14 </em>° <em>;</em> <em>83 </em>°

Step-by-step explanation:

( 14x - 1 )° + ( 2x + 2 )° = 97°

14x - 1 + 2x + 2 = 97

16x = 96

x = 6

m∠BCA = ( 2 × 6 + 2 )° = <em>14 </em>°

m∠ABC = ( 14x - 1 )° = <em>83 </em>°
