Answer:
The scatter diagram that contains the correlation coefficient closest to r = 1 is the first one shown in the attached images.
Step-by-step explanation:
The correlation coefficient "r" measures how much two variables x and y are related. When the variables are highly related, the value of r is closer to one and the points contained in the scatter diagrams are assimilated more and more to a line. When the value of r is positive the relation is crescent and therefore the slope of the line drawn by the points in the diagram has a positive slope
Therefore, to answer this question, one must search among the attached images for the dispersion diagram in which the points resemble a straight line with a positive slope.
The scatter diagram that meets the requirements mentioned is the first one that appears in the attached images

Answer: x = 8√7, y = 4√21
Explanation:
1) There are three triangles.
2) The small triangle of the right has a right angle, and the sides are the height, x and 16.
3) The small triangle of the left, has a righ angle, and the sides are the heigth, y and 12.
4) The big triangle has a right angle, and the sides are the x, y and 28.
5) Set three equations using Pytagora's theorem for the three triangles..
a) y^2 + x^2 = 28^2 = 784
b) h^2 + 12^2 = y^2
c) h^2 + 16^2 = x^2
6) Subtract b) from c)
16^2 - 12^2 = x^2 - y^2
=> x^2 - y^2 = 112
add x^2 - y^2 = 112 with the equation a)
x^2 - y^2 = 112
x^2 + y^2 = 784
----------------------
2x^2 = 112 + 784
2x^2 = 896
x^2 = 896 / 2 = 448
x = √448
x = 8√7
7) now you can use any a) to find y:
y^2 + x^2 = 784
=> y^2 = 784 - x^2
=> y^2 = 784 - 448
=> y^2 = 336
=> y = 4√21
Answer: x = 8√7, y = 4√21
Answer:
Store T sells apples at the lowest rate
$1.16
Step-by-step explanation:
which of these is a true statemnt
Store R sells apples at the lowest rate
Store T sells apples at the lowest rate
Store s charges a lower rate than Store T
Store t charges the same rate as Store R
Given:
Store R= $1.20 per pound
Store S =$5.00 for 4 pounds
Store T=$3.48 for 3 pounds
Find the price of apple per pound
Store R=1.20 per pound of Apple
Store S=$5.00/4
=$1.25 per pound of Apple
Store T=$3.48/3 pounds
=$1.16 per pound of Apple
From the statements above,
Store T sells apples at the lowest rate
