Which is most likely the correlation coefficient for the set of data shown?

Sonja [21]3 years ago

The correlation coefficient of a scatter plot with line of best fit shown will be the slope of the line.

We can eliminate last 2 choices because the line is clearly a downward sloping line and it's slope wont be positive.

From the first two, it looks like the plot's slope is very close to -1. So we take -0.91, instead of -0.35. <em>[note: 0.91 is more steeper than 0.35 (which is very relaxed)]</em>


ANSWER: -0.91

Can u solve both 20. and 22.<br><br> Geometry
SCORPION-xisa [38]

Hey there!!

(1) Both the angles sum up to be 180.

(2) Both the angles sum up to be 90

_________________

(1) 4x+5+8x-5=180

... 12x=180

... x= 180/12

... x = 15

________________

(2) 4z+3z+6=90

... 7z+6=90

... 7z=84

... z=84/7

... x=12

Answer:

side c = 150 feet of flowers

Area = 5400 feet squared

concert question:

The converse of the Pythagorean theorem can help you determine whether the roped off area is in the shape of a right triangle because you use the side lengths of each square and enter them into the equation, and if the equation is true, then it is a right triangle

Concession stand question:

The school banner can fit across the length of the concession stand

the following information is missing

The length if the sides: c is 50 feet long, b is 40 foot long, and a is 30-foot long.

The distance between the two red stars of the picture makes the hypotenuse of a right triangle, where two sides of length a (30 ft) are the legs. From Pythagorean theorem, diagonal of square A is:

diagonal² = 30² + 30²

diagonal = √1800  = 42.43 ft

which is longer than the banner.

Blueprint question:

No, diagonal of square C is 70.71ft

2nd blueprint question:

50 square root 2

Gardening group:

50.24 yards
