N a typical 2-pound bag of M&Ms contains 500 individual pieces, of which... 120 are blue, 70 are brown, 80 are green, 100 are orange, 60 are red, and 70 are yellow. If I randomly select one M&M candy from the bag, what is the probability that candy will be red?
Answers
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

Tamika makes $ 378.00 on the sale of a home theater system that costs $9.000.00. Express her rate of commission as a percent rounded to the nearest whole number
Answers
Answer:
4%
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,
if it is equal to or greater than 5, add 1 to the number before the decimalif it is less than five, add 0 to the number before the decimaltwo is less than 5, thus we would add zero to 4.
4.2% becomes 4%
Solve for x.

Answer: x=2

Please mark brainliest
Answer:
x = 2
Step-by-step explanation:
The whole goal when solving problems like this is to get the x alone. So the first step would be to get the -3 over to the other side. To do this, you would add 3 to each side of the equation, so that the -3 on the left side cancels out.
-2x - 3 = -7
+3 +3
-2x = -4
The next thing you need to do is divide each side by -2. You would do this because right now, the equation reads "negative two times x equals negative four". When you divide a multiplication problem, it cancels out, so you are left with just the x.
-2x = -4
÷ -2 ÷ -2
x = 2
You now have the value of x.

Una garrafa de aceite equivale a 5 botellas y 3 garrafas es igual a 7, las cuales suman 11 litros, ¿Cuál es las capacidad de una botella y una garrafa?
Answers
Respuesta:
Botella, B = 0.5
Jarra, C = 2,5
Explicación paso a paso:
Dejar :
Garrafa = C
Botella = B
C = 5B - - - - 1)
3 garrafas más 7 botellas = 11 litros
3C + 7B = 11
C = 5B
3 (5B) + 7B = 11
15B + 7B = 11
22B = 11
B = 11/22
B = 1/2 = 0,5
Sustituyendo B = 0.5 en 1)
C = 5B
C = 5 (0,5)
C = 2,5
