Answer:
B
Step-by-step explanation:
mean = average. to find it, add all terms, and then divide by the number of terms.
find the mean of group a:
(1+1.5+3+3.2+2.8+1.5+1.8+2.5+2.2)/9 = 2.16
find the mean of group b:
(2+2.5+3.2+3+1.8+2.4+3+1.5+1/8)/9 = 2.1694
group b is larger.
answer = b
Answer:
Length = 65 m
Width = 23 m
Step-by-step explanation:
Width = w
Length = 3w - 4
Perimeter of rectangle = 176 m
2*(length + width) = 176
2*( 3w - 4 + w ) = 176
2* ( 4w - 4) = 176
2*4w - 2*4 = 176
8w - 8 = 176 { add 8 to both sides}
8w = 176 +8
8w = 184
8w/8 = 184/8
w = 23 m
Length = 3w - 4
= 3*23 - 4
= 69 - 4
Length = 65 m
Answer:
1/216
Step-by-step explanation:
The ratio of volumes of similar shapes is the cube of the scale factor. The filled portion of the cone is similar to the entire cone.
<h3>Linear scale factor</h3>
If the filled height is 1/6 of the total height, the scale factor for linear dimensions is 1/6.
<h3>Volume scale factor</h3>
The scale factor for the volume is the cube of the scale factor for linear dimensions. it is ...
(1/6)³ = 1/216
The volume of the filled portion of the cup is 1/216 of the volume of the cup.
