Answer:
The representative sample contained more girls than boys.
(2x+1)(x-2) = 2x^2 - 4x +x -2= 2x^2-3x-2
Answer:
a= d and b= b
Step-by-step explanation:
circumference falls hand and hand with diameter and radius
a has a circumference of about 301 inches
b is about 62 inches
c is about 75 inches
d is about 314
The ratios are Surface area ⇒ 4 : 25 Height ⇒ 2 : 5 and Volume ⇒ 8 : 125
<h3>How to determine the ratios?</h3>
The scale factor is given as:
m : n = 2 : 5
For the area, we take the square of the ratios.
i.e.
Area = 2^2 : 5^2
Evaluate
Area = 4 : 25
For the volume, we take the cube of the ratios.
i.e.
Volume = 2^3 : 5^3
Evaluate
Volume = 8 : 125
The given scale factor can be used for the height of the model and the original bicycle
Hence, the ratios are
Surface area ⇒ 4 : 25
Height ⇒ 2 : 5
Volume ⇒ 8 : 125
