Answer:
a statistical question is one that we can answer using data
example: How much do 5 gorillas weigh at the zoo called wilderness?
Answer:
V = 396 cm³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the height of prism )
A = 
bh ( b is base and h perpendicular height )
here b = 9, h = 8 , then
A = × 9 × 8 = 4.5 × 8 = 36 cm² , so
V = 36 × 11 = 396 cm³
Answer:
x = ±20
Step-by-step explanation:
Step 1: Write equation
x² = 400
Step 2: Square root both sides
x = ±√400
x = ±20
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
20² = 400
400 = 400
(-20)² = 400
400 = 400
Step-by-step explanation:
Perimeter = 2 * (Side A + Side B)
= 2 * (3x + 2 + x - 5)
= 2 * (4x - 3)
= 8x - 6.
We have 8x - 6 = 50, so 8x = 56 and x = 7.
Length of rectangle = 3(7) + 2 = 23.
Width of rectangle = (7) - 5 = 2.
