Answer:120 on each
Step-by-step explanation:
Average is the total of x divide by number of x.
Here, we have,
x = 55, 64, 60, 61
number of x = 4
Total of x = 55 + 64 + 60 + 61 = 240
So, the average is,
240 / 4 = 60
This is the concept of quadratic equations, solving the equation 2x^2-12x+20=0 using the formula we get:
x=[-b+/-sqrt(b^2-4ac)]/(2a)
from our equation, a=2,b=-12 and c=20
x=[-(-12+/-sqrt((-12)^2-4*2*20)]/(2*2)
x=[12+/-sqrt(144-160]/4
x=[12+/-sqrt(-16)]/4
x=[12+/-4i]/4
x=[3+\-i]
the answer is A] 3+/-i
Step-by-step explanation:
3 of the 4 options aren't prisms
A is a cuboid
B is a cube
C is a prism
D is a pyramid
These are improper fractions so you need to change them to mixed numbers. 5/2 is 2 1/2 and 5/3 is 1 2/3. From there you can tell which is smaller and which is larger.
