Answer: x=7
Step-by-step explanation: 4(7+4)=44. 7(7)-5=44.
Answer:
I. 60%
II. 75.4 kg
Step-by-step explanation:
We will use the z-scores and the standard normal distribution to answer this questions.
We have a normal distribution with mean 69 kg and variance 25 kg^2 (therefore, standard deviation of 5 kg).
I. What percentage of adult male in Boston weigh more than 72 kg?
We calculate the z-score for 72 kg and then calculate the associated probability:

II. What must an adult male weigh in order to be among the heaviest 10% of the population?
We have to calculate tha z-score that satisfies:

This happens for z=1.28 (see attachment).
Then, we can calculate the weight using this transformation:

Answer:
8
Step-by-step explanation:
Step 1: Write polynomial
4x⁵ - 16x² + 13x⁸
Step 2: Rearrange
13x⁸ + 4x⁵ - 16x²
The degree of a polynomial is the highest power. In this case, our degree would be 8 because of the x⁸ term being the largest exponent.
Answer:
2y I think ( I am not sure tho)
E=Pt where e= energy P= power t= time
E=1.200kiowatt/15 minutes
E={1200/100*1000}/15
E=800 watt/minute
