I think It’s C or the 3rd one
You expect to get heads 250 times and tails 250 times, So, if this is the case and you flip your coin 500 times, you would most likely get heads 257 times and tails 243 times.
Does that make sense?
B, 27 ft²
2*3 + 7*3 = 27
but for this one you could just actually count the tiles
Answer:
7/4
Step-by-step explanation:
since 1=4/4
4/4+3/4=7/4
Answer:
C=$(4.30xy+5.40(xz+yz))
Step-by-step explanation:
Surface Area of a Cuboid=2(LW+LH+HW)
Since the top is open
Surface Area = LW+2(LH+HW)
If Length = x feet,
Width =y feet
Height = z feet
Surface Area = xy+2(xz+yz)
Area of the base=xy
If it costs $4.30 per square foot to build the base
Cost of the base=Cost Per Square Foot X Area = $4.30xy
Area of the sides =2(xz+yz)
If it costs $2.70 per square foot to build the sides
Cost of the sides=Cost Per Square Foot X Area of the sides
= 2.70 X 2(xz+yz)
=5.40(xz+yz)
Cost of Constructing the Box = Cost of Constructing the Base + Cost of Constructing the Sides.
Therefore,
C=$(4.30xy+5.40(xz+yz))
