Answer:
a. 0.15%
Step-by-step explanation:
The Z-score of a 945-lb car is ...
(X -μ)/σ = (945 -3550)/807 ≈ -3.23
The empirical rule tells you that about 99.7% of the normal distribution is within 3σ of the mean, so less than 1/2 of 0.3% will be more than 3σ below the mean. The most appropriate of these choices is 0.15%.
_____
The CDF of a normal distribution changes rapidly in the tails, so the difference between 3σ and 3.23σ is pretty large. The actual probability is nearer 0.062%.
To fully answer this question you would have to list the plynomials or provide a picture of the question, but the answer you're looking for will have the highest exponent be 2 an example of a plynomial like this would be 94x^2 - 54y + 17x - 49
Answer: your gonna add 3,000+ 5,000 then you will add test answer to 157.50 then you’ll put the answer for 3,000+5,000 then you’ll put that in the first box then you’ll add that number two 157.50
