Answer:

x= 1 ±√21/3

x= 2.52753

x= - 0.527525

Step-by-step explanation:

-(-6) ±√-6² - 4 (3) (-4) / 2(3)

6±√36 -(-48) / 6

6±√84/6

6±2√21/6

6/6 ±2√21/6

1±√21/3

1+ √21/3 = 2.52753

1-√21/3= - 0.527525

Answer:

0.12

Step-by-step explanation:

Number of red candies = 60

Total number of candies = 500

Recall :

Probability of event A = number of occurrences of A / total number of occurences

= required outcome / Total possible outcomes

The probability of randomly selecting a red candy is :

= number of red candies / total number of candies

= 60 / 500

= 0.12

Step-by-step explanation:

Answer:

Step one: Decide if the two terms have anything in common, called the greatest common factor or GCF. If so, factor out the GCF. Do not forget to include the GCF as part of your final answer. In this case, the two terms only have a 1 in common which is of no help.

Step 2: Rewrite the original problem as a difference of two perfect cubes.

Step 3a: “Write What You See” If you disregard the parenthesis and the cubes in step 2, you should see:

Step 3b: “Square-Multiply-Square” If you square the first term, x, you get x2. If you multiply the two terms, x and 4, you get 4x. Finally, if you square the second term, 4, you get 16.

Step 3c: “Same, Different. End on a Positive” This will determine the signs of the problem. The first sign should be the same as the original question, the next sign should be different then the first, and the last sign should always be positive.

Step 4: Write the final answer.

Step-by-step explanation:

Answer:

Sample space: {1, 2, 3, 4, 5, 6}

Simple event

Step-by-step explanation:

Sample space is a list of all the possible outcomes.

This is a simple event because you are only doing one event, such as rolling a die.

A compound event would be multiple simple events, such as flipping a coin and choosing a marble from a bag.

The answer is 27 m² and 9 m² of blue and brown fabric will be used respectively.

A square pyramid is a three-dimensional shape that has a total of four triangular faces.  

A most famous example of such a pyramid in real life is the Great Pyramid of Giza.

The sides are triangular faces are 3 m and 4.5m

Height of the prism is 4.5m and the side of the square base is 3m

The surface area for triangular face is (1/2) *  base * height

= (1/2) * 3 * 4.5

= 6.75 m²

For four faces the surface area of the blue fabric required is side * side

= 4 * 6.75

= 27 m²

For the base , brown fabric is being used and the surface area of the base is

= 3 * 3

= 9 m²

Therefore 27 m² and 9 m² of blue and brown fabric will be used respectively.

Step-by-step explanation:

commission rate = (amount earned on sales / total cost of items sold) x 100

[tex]\frac{378}{9000}[/tex] × 100 = 4.2%

To convert to the nearest whole number, look at the first number after the decimal,

two is less than 5, thus we would add zero to 4.
