Louis traveled 7,144 miles
Answer:
y < 
x
Step-by-step explanation:
Since the line is dotted and shaded down that mean the sign is <.
The slope is rise over run or 3/4.
Since the line intercepts the y-intercept at (0,0) that means that the y-int is 0
So the full equation is y < 3/4 x

Step-by-step explanation:
Hello!
X: Cholesterol level of a woman aged 30-39. (mg/dl)
This variable has an approximately normal distribution with mean μ= 190.14 mg/dl
1. You need to find the corresponding Z-value that corresponds to the top 9.3% of the distribution, i.e. is the value of the standard normal distribution that has above it 0.093 of the distribution and below it is 0.907, symbolically:
P(Z≥z₀)= 0.093
-*or*-
P(Z≤z₀)= 0.907
Since the Z-table shows accumulative probabilities P(Z<Z₁₋α) I'll work with the second expression:
P(Z≤z₀)= 0.907
Now all you have to do is look for the given probability in the body of the table and reach the margins to obtain the corresponding Z value. The first column gives you the integer and first decimal value and the first row gives you the second decimal value:
z₀= 1.323
2.
Using the Z value from 1., the mean Cholesterol level (μ= 190.14 mg/dl) and the Medical guideline that indicates that 9.3% of the women have levels above 240 mg/dl you can clear the standard deviation of the distribution from the Z-formula:
Z= (X- μ)/δ ~N(0;1)
Z= (X- μ)/δ
Z*δ= X- μ
δ=(X- μ)/Z
δ=(240-190.14)/1.323
δ= 37.687 ≅ 37.7 mg/dl
I hope it helps!
This would result in 322.5. you get this by moving the decimal place two to the right
Answer:
5y=4+3x, 5y-3x=-1
Step-by-step explanation:
To be parallel they must have different constants but the same slope.
5y-3x=-1
5y=-1+3x and 5y=4+3x fit these requirements.
