The following probabilities are based on data collected from U.S. adults. Individuals are placed into a weight category based on
1 answer:
Answer:
<em>The probability that a randomly selected U.S. adult is not underweight is 0.979</em>
Step-by-step explanation:
<u>Probability Distribution</u>
Four events were measured and their probabilities computed as follow
Please note the sum of the probabilities is 1, thus the distribution is correctly expressed. We want to compute the probability that a randomly selected U.S. adult is not underweight.
Knowing the adult doesn't belong to the underweight category, then they must belong to any of the other categories, thus the probability is the sum of their individual probabilities or (easily computed), the total probability minus the underweight probability:
The probability that a randomly selected U.S. adult is not underweight is 0.979

Grant needs to ride at least 13.33 miles to male at least $ 15.00 a day
<em><u>Solution:</u></em>
Given that Grant has an agreement with Brian to rent the bike for $35.00 a night
He charges customers $3.75 for every mile he transports them
Grant needs to make at least $15.00 a day
To find: miles needed to ride
From given question, He charges customers $3.75 for every mile he transports them
So if he transports for "x" miles he would get,
So the profit he gets is $ 3.75 and initial cost invested to rent bike is $ 35. Also, Grant needs to make at least $15.00 a day
So we can frame a inequality as:
So he needs to ride atleast 13.33 miles to male atleast $ 15.00 a day
