The aquarium has a scale model of a great white shark in there gift shop if the scale of the model is 2in 7ft what is the actual length of the shark​

i assume the line plot is the % difference, the original 95% vs 92% has a difference of 3%,

the 10 random values center around 3% and 3% has the most occurrences of the 10.

the average value for the 10 is 2.9%, so that is within .1 of the original 3%

so it should be significant, not sure what criteria you are supposed to use?

is there a p or z test involved?

hope this !

answer:

it has rotational symmetry about the origin.

step-by-step explanation:

if we rotate it 180 degrees about the origin we get the same graph.

another rotation   of 180 degrees also gives the same graph, so we have a rotational symmetry of 2.

answer:

b. arithmetric

step-by-step explanation:

answer:

y= -4x+4

step-by-step explanation:

y= mx+c is slope-intercept form of equation of line where m is slope and c is y-intercept.

in question statement,we observe that

x-intercept: (1,0)

y-intercept: (0,4)

we have to find slope for line.

slope= m =

slope= m = 4-0/0-1

slope = m = 4/-1

slope = m = -4

y-intercept= c = 4

putting the values of slope and y-intercept in slope intercept form,we get

y= -4x+4 is equation of line that has intercepts (1,0) and (0,4).
