Answer:
A
Step-by-step explanation:
Carlos' score was 2 standard deviations from the mean, so his z-score was 2.0. You can either use the empirical 68-95-98.5 rule, or you can plug it into your calculator as <u>normalcdf(-999, 2) = .977</u>
So 97.7% of people had a score lower than Carlos!
.977 * 1.5 million = 1,465,500 people
If by standard form, you mean ax+by= c, here is how to solve.
To write the equation in standard form, move each variable term to the left side of the equation and simplify.
y+2=3/5(x + 5)
y+2= (3/5*x) + (3/5*5)
y+2= 3/5x + (3*5)/5
y+2= 3/5x +15/5
y+2= 3/5x + 3
subtract 3/5x by both sides
-3/5x+y+2= 3
subtract both sides by 2
-3/5x+y=1
multiply by 5 to eliminate fraction
-3x + 5y= 5
ANSWER: -3x + 5y= 5
Hope this helps! :)
Carla rested at: -33
Jim rested at: -35
Now it is up to you to figure who was at the greater depth. I did the calculations for you all you have to do is compare:)))) GOOD LUCK its not hard now
Answer:
Option A
Step-by-step explanation:
Slope of a line passing through two points 
and 
is given by,
Slope = 
Line shown in the graph is passing through two points (2, 8000) and (4, 7000).
Therefore, slope of the given line = 
= -500 feet per mile
Which means, altitude decreases by 500 ft every mile.
(Negative sign represents the decrease)
Option A is the correct option.
