Answer:
-17.85
Step-by-step explanation:
=> y-x+z
Putting y = 4, x = 22 and z = 0.15
=> 4-22+0.15
=> -18+0.15
=> -17.85
Answer:
A= 16 cubes²
Step-by-step explanation:
The length, or the base, is 4 units. The height of the shape is 2, and the width is 2. If we use the formula of volume, <em>l·w·h</em>, we can say that V=4x2x2. So, 4x2x2=16.
Answer:
42¼ in³
Step-by-step explanation:
volume = 6½×2×3¼= 42¼ in³
Answer:
P(1 or 2) = 2/9
Step-by-step explanation:
OR means we add each probability
If it is 9-sided, I will assume the die will be numbered 1-9
Probability of getting a 1 in mathematical notation is:
P(1) = 1/9
Probability of getting 2:
P(2) = 1/9
We add their probabilities since we want to know if we get either 1 or 2
P(1) + P(2) = 1/9 + 1/9 = 2/9
If the question asked what the probability was of getting a 1 and a 2 by rolling the die twice, we would multiply the probabilities together
1/9 x 1/9 = 1/81
