C. 1 for every 6.25
D. 0.5 for every 3.125</span>
Answer:
Step-by-step explanation:
Assuming this complete question:
"Suppose a certain species of fawns between 1 and 5 months old have a body weight that is approximately normally distributed with mean kilograms and standard deviation kilograms. Let x be the weight of a fawn in kilograms. Convert the following z interval to a x interval.
"
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where and
And the best way to solve this problem is using the normal standard distribution and the z score given by:
We know that the Z scale and the normal distribution are equivalent since the Z scales is a linear transformation of the normal distribution.
We can convert the corresponding z score for x=42.6 like this:
So then the corresponding z scale would be:
Answer:
Davids brother has more then 7 hats
Step-by-step explanation:
because together they have 19 and david himself has 12. 19-12 equals 7 and the question states that have more then 19 hats together so we know his brother has to have 7 hats but we dont know how many more he has.
D: -2/3
That's your answer...
Hope this helps! Please give me a 5-rate and a thanks! (and brainliest) thanks!
Answer:
D)- Less than 1 Mile
Step-by-step explanation: as current= 1 1/2 Miles = 3/2 Miles
Total plans= 2 1/3= 7/3 Miles
Difference= (7/3)-(3-2)
= 5/6 Miles
