Answer:
Claire traveled for 9 days.
Step-by-step explanation:
Given:
Total Distance traveled = 701 miles
Distance traveled each day = 80 miles
Distance traveled on last day = 61 miles
We need to find the number of days Claire traveled.
Solution:
Let the number of days Claire traveled be denoted by 'd'.
Now we can say that;
Total Distance traveled is equal to sum of Distance traveled each day multiplied by number of days and Distance traveled on last day.
framing in equation form we get;
![80d+61=701](https://tex.z-dn.net/?f=80d%2B61%3D701)
Now Subtracting both side by 61 using Subtraction Property of Equality we get;
![80d+61-61=701-61\\\\80d = 640](https://tex.z-dn.net/?f=80d%2B61-61%3D701-61%5C%5C%5C%5C80d%20%3D%20640)
Now Dividing both side by 80 we get;
![\frac{80d}{80}=\frac{640}{80}\\\\d=8](https://tex.z-dn.net/?f=%5Cfrac%7B80d%7D%7B80%7D%3D%5Cfrac%7B640%7D%7B80%7D%5C%5C%5C%5Cd%3D8)
Hence Claire traveled 80 miles in 8 days and 61 miles on last day making of total <u>9 days</u> of travel.
Answer:
y=2x+3
Step-by-step explanation:
Use the equation: y=mx+b
m is the slope (2 in this case)
b is the y intercept (3 in this case)
So the equation of the line would be y=2x+3
Yes..it does. To be a function, all the inputs (x's) have to be different numbers...there can be no repeating x's...there can be repeating outputs (y's)...just not the x's
Answer:
Hip breadths less than or equal to 16.1 in. includes 90% of the males.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 14.5
Standard Deviation, σ = 1.2
We are given that the distribution of hip breadths is a bell shaped distribution that is a normal distribution.
Formula:
![z_{score} = \displaystyle\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z_%7Bscore%7D%20%3D%20%5Cdisplaystyle%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
We have to find the value of x such that the probability is 0.10.
P(X > x)
Calculation the value from standard normal z table, we have,
![P(z < 1.282) = 0.90](https://tex.z-dn.net/?f=P%28z%20%3C%201.282%29%20%3D%200.90)
Hence, hip breadth of 16.1 in. separates the smallest 90% from the largest 10%.
That is hip breaths greater than 16.1 in. lies in the larger 10%.
answer:
48 + 12 + 35 + 57 + 42 + 15 + 74 + 29 = 312
divide by number of numbers,
312 / 8 = 39
the mean is 39.
