Is the relationship shown by the data linear? If so, model the data with an equation. X:1,5,9,13 Y:5,10,15,20

ryzh [129]

Let
A (x1,y1)-------> (1,5)
B (x2,y2)------> (5,10)
C (x3,y3)------> (9,15)
D (x4,y4)------> (13,20)

find the slope
AB
m=(10-5)/(5-1)-----> m=5/4

find the slope
CB
m=(15-10)/(9-5)-----> m=5/4

find the slope
DC
m=(20-15)/(13-9)-----> m=5/4

so
<span>the relationship shown is linear
</span>
<span>to model the data with an equation find the equation of a line
</span>with m=5/4 and point A (1,5)
y-y1=m*(x-x1)-----> y-5=(5/4)*(x-1)----> y=1.25x-1.25+5-----> y=1.25x+3.75

the equation to model data is
y=1.25x+3.75

see the attached figure

The distribution of the amount of money spent by students for textbooks in a semester is approximately normal in shape with a me

vladimir2022 [97]

Answer:

b. between 195 and 275 dollars.

Step-by-step explanation:

The standard deviation rule, or the 68-95-99.7 rule, states that, for a normally distributed random variable X:

68% of the measures are within 1 standard deviation of the mean

95% of the measures are within 2 standard deviations of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean 235, standard deviation 20.

According to the Standard Deviation Rule, in a semester, most (95%) of the students spent on textbooks:

Between 235 - 2*20 = 195 dollars and 235 + 2*20 = 275 dollars.

So the correct answer is:

b. between 195 and 275 dollars.
