Step-by-step explanation:
Bryce wrote the linear regression equation y = 1. 123 x minus 6. 443 to predict the armspan, y, of a person who is x inches tall. Riley has an armspan of 67. 5 inches. Which is the best prediction of Riley’s height? 54. 36 inches 65. 84 inches 66. 55 inches 69. 36 inches.
The best prediction of Riley’s height is 65.84 inches and it can be determined by using the linear regression equation.
Given that,Bryce wrote the linear regression equation,
[tex]\rm y=1.123x-6.443[/tex]
To predict the arm span, y, of a person who is x inches tall.
Riley has an arm span of 67.5 inches.
We have to find,Which is the best prediction of Riley’s height?
According to the question,To predict the arm span, y, of a person who is x inches tall.
Riley has an arm span of 67.5 inches.
The linear regression equation is,[tex]\rm y=1.123x-6.443[/tex]
Where the arm span, y, of a person who is x inches tall.
Riley has an arm span of 67.5 inches,
Then,
The best prediction of Riley’s height is,
[tex]\rm 67.5 = 1.123x -6.443\\\\67.5+6.443=1.123x\\\\ 73.943 = 1.123x\\\\ x = \dfrac{73.943}{1.123}\\\\ x = 65.84 \ inches[/tex]
Hence, The best prediction of Riley’s height is 65.84 inches.

The 2 pentagons above are similar. What is the area of the smaller pentagon?
Answer:
16^2
Step-by-step explanation:
All you have to do is do 64 *.25 and you get 16
The area of the smaller pentagon is 4 in². thus option B is correct.
How to determine the area of the smaller pentagon?The ratio of the side lengths are given:
Small : Large = 3.5 : 14
The area of the larger pentagon is given;
Area = 64 in²
By Using the given parameters, the area of the small pentagon:
Area = (Small/Large)² * Area of Large
Area = (3.5/14)² * 64
Area = 4
Hence, the area of the smaller pentagon is 4 in². thus option B is correct.

The perimeter of a rectangular piece of land is 280m. People divide the land into two small pieces: a square, a rectangle. The total perimeter of the two small plots is 390m. Calculate the area of the original piece of land.
Step-by-step explanation:
Length of the Rectangular piece of the land = 12 + 1/2 m = 25/2 m
Breadth of the Rectangular piece of the land = 5 + 1/5 m = 26/5 m
If 4 small square flower bed of side length 1 m are made at center.
To find: Area of the rectangular land , Perimeter of the rectangle and Area of land left when flower bed are mad.
Perimeter of the rectangle = 2 × ( length + breadth )
= 2 × ( 25/2 + 26/5 )
= 2 × ( 177/10 )
= 177/5 m
= 35.4 m
Area of the rectangular land = Length × Breadth
= 25/2 × 26/5
= 5 × 13
= 65 m²
Area of a flower bed = side × side = 1 × 1 = 1 m²
Area of 4 flower bed= 4 × 1 = 4 m²
Area left in the land = 65 - 4 = 61 m²
Therefore, Perimeter of the land is 35.4 m
Area of land is 65 m²
Area of the land left after flower beds is 61 m²
