Answer:
2x + 3y2

6xy3
Step-by-step explanation:
Density = m/v with mass being in grams and volume in mL......
192 grams/250 mL = 0.768 g/mL
The unit rate is going to be calories per serving....calories / serving
Food A :
150 / (3/4) =
150 * 4/3 =
600/3 =
200 calories per serving
Food B :
250 / (2/3) =
250 * 3/2 =
750/2 =
375 calories per serving
Therefore, Food A has fewer calories per serving <==
Answer:
70%
Step-by-step explanation:
Two Steps to Convert a Fraction to a Percent
Use division to convert the fraction to a decimal:
7/10 = 7 ÷ 10 = 0.7
Multiply by 100 to get the percent value:
0.7 × 100 = 70%
Therefore the answer is 70%.
Answer:
Mean = 10.2
Standard deviation = 4.0
Step-by-step explanation:
The average age = mean age
Mean = (16 + 10 + 5 + 7 + 13)/5
Mean = 51/5 = 10.2
What is the standard deviation will be square root of variance
(16 - 10.2) + (10 -10.2) + (5-10.2) + (7-10.2)+( 13-10.2)
5.8 + 0.2 -5.2 - 3.2 + 2.8
Square each number
33.64 + 0.04 + 27.04 + 10.24 + 7.84
Variance = 78.8/5 = 15.76
Standard deviation = 3.969 = 4.0
