Answer:
Step-by-step explanation:
Given
Cost of Textbooks ---- Frequency
$25 up to $35 ----- 2
$35 up to $45 ------- 5
$45 up to $55 ------- 7
$55 up to $65 ------ 20
$65 up to $75 ---- -- 16
Required
Determine the relative class frequency for the $25 up to $35 class
First, we need to get the total frequency
Next, is to write out the frequency of $25 up to $35 class
Divide this frequency by the total frequency; This gives the relative frequency
Hence;
Option D answers the question
Answer:
60
Step-by-step explanation:
10 / 2 = 5
9 +3 = 12
5 x 2 = 60
Answer:
90.80
Step-by-step explanation:
6x+4
= (6)(13)+4
= 78+4
=82
3x
=(3)(13)
= 39
So we know the sides are 39 and 82
Pythagoras theorem in triangles
= a2+b2= c2
Now, we know the value of a and B but not c (the hypotenuse)
Therefore,
c2 = (39)^2 + (82)^2
= 1521+ 6724
= 8245
so, c = √8245
= 90.80 unitd
Given the coordinates of the three vertices of a triangle ABC,
the centroid coordinates are (x1+x2+x3)/3, (y1+y2+y3)/3
<span>so (-4+2+0)/3=-2/3, ]2+4+(-2)]/3=4/3
so the coordinates are (-2/3, 4/3)</span>
Answer:
Step-by-step explanation:
volume=πr^2h
461.58=3.14*r^2*12
461.58=37.68*r^2
461.58/37.68=r^2
12.25=r^2
=r
3.5=r
diameter=radius*2
=3.5*2
=7 in.
