Area of a circle = pi * r^2
A = (3.14) * 8^2
A = 3.14 * 64
A =200.96 units ^2
Randy's cat if 5 kilograms, so therefore the tiger's mass is 27 times larger than the mass of Randy's cat.
Answer:
The mean, μ is 2.5063 and
The standard deviation, σ = 2.0499 × 10⁻²
Step-by-step explanation:
Here we have
and
10% have length < 2.48 in while
5% have length > 2.54 in
and
From the z score table
Critical z at 10% to the left = -1.282
Critical z at 5% to the right = 1.645
Therefore, the equations become
-1.282σ = 2.48 - μ → μ -1.282σ = 2.48
1.645σ = 2.54 - μ → μ + 1.645σ = 2.54
Solving the above equations gives
The mean, μ = 2.5063 and
The standard deviation, σ = 2.0499 × 10⁻².
Answer:
P(Y) = 18/720 = 0.025
P(P) = 16/720 = 0.022
P(B) = 6/720 = 0.0083
Step-by-step explanation:
<em>I couldn't find the options but I will try to help you considering that the question is about probabilities.</em>
Let the events be:
- Y = a yellow flower is selected
- P = a pink flower is selected
- B = a blue flower is selected
We can define the probability of an event X as:
P(X) = number of favorable outcomes for event X / total number of outcomes
The total number of outcomes is 720 (total number of flowers in the piece of fabric).
When selected one flower at random from the fabric, the probability that a yellow flower is selected is:
P(Y) = 18/720 = 0.025
When selected one flower at random from the fabric, the probability that a pink flower is selected is:
P(P) = 16/720 = 0.022
When selected one flower at random from the fabric, the probability that a blue flower is selected is:
P(B) = 6/720 = 0.0083
Answer:
no similar doesn't mean it's congruent so 120 would be the answer
hope this helps
have a good day :)
