(5/4) / (2/3)
= 5/6
therefore: he has run 5/6 miles so far
Answer:
Probability that X <32 degrees
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )
Step-by-step explanation:
Given that a city's mean minimum daily temperature in February is 22 degrees Upper F, with std deviation 6 degrees.
Let X be the minimum temperature in February
Then X is N(22,6)
To calculate percentage of days in February has minimum temperatures below freezing (32 degrees Upper F )
Probability that X <32 degrees
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )
Answer:
The iron will need 10 amps
Step-by-step explanation:
The extension cord can support uptown 8 amps.
The iron has a 1200watts labelled on it
Converting watts to amps by dividing by 120 gives:
1200watts/120 =10 amps
The iron is 10amps
Answer: 1
Step-by-step explanation:
A formula for the slope of a line is rise/run.
First let’s find the ‘rise’
To find the rise, we must look at the difference between the elevation of the points. We can find the rise by subtracting y1 from y2. 7-3=4, so the rise is 4
Run is the same concept. We must subtract x2 - x1.
2-(-2)=2+2=4
So the rise is 4 and the run is 4. There for rise/run = 4/4 =1
The slope of the line is 1
Answer:
No
Step-by-step explanation:
In order for a group of points to be considered a function, there has to be one exact y value for each x value. In other words, the same x value can't appear twice in the relation. Since 15 appears twice in the relation, it is not a function.
