Answer:
slope=200
y-intercept=500
Step-by-step explanation:
Equation of straight line in slope intercept form is given as

here
slope=m=200/day
y-intercept=b=500

X would be your variable <span>A variable is a </span>quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x , y , and z are common generic symbols used for variables.
Witch means that X can not be more than -15 it has to be less or equal to.
Answer:
15750
Step-by-step explanation:
Answer:
8.5 hrs
Step-by-step explanation:
-A 75th percentile mathematically means that 75% of the time data points are below that value and 25% of the time are above that value.
-We plot the given our data {3 12 2 3 5} to determine the 75th percentile
#We can use
to plot our boxplot.
-From the plot, we find our 75th percentile to be 8.5 hrs
Hence, 75% of the time the number of hours spent to prepare was less than 8.5hrs.
