Answer:the mean is 6.1 the mode is 5 and 7.
Step-by-step explanation: the mean is 6.1 because the number add up to 61 and there are 10 numbers 61/10=6.1
The mode is 5 and 7 because they occur most frequently
C(s) = 175s + 4500 or y = 175x + 4500
cost of 12 tons of sugar...
C(12) = 175(12) + 4500
C(12) = 2100 + 4500
C(12) = 6600....so 12 tons of sugar will cost u $ 6600
Answer:
519
Step-by-step explanation:
Let's assume that the scores for the national verbal proficiency test follow a normal distribution.
Mean score (μ) = 500
Standard deviation (σ) = 75
According to a Z-score table, the score for the 60th percentile is roughly z = 0.253
For any score "x", the z-score is given by:
For z = 2.53:
The raw score to the 60th percentile is 519.
Answer:
B and D
Step-by-step explanation:
One thing is for certain. The final answer will be 1/r^12 or r^(-12)
When written as the given of (r^-4)^3, the powers are multiplied.
The first one is false. There are 4 factors of r^-4 If you get an answer that says it is true, then the question means that r^-4 is 3 equal factors of r^-12
B is true
C: not true. The exponents are multiplied, not added.
D is true
E: not true. This is the same thing as C.
