Step-by-step explanation:
(2*5)*4 = 10*4 = 40
2*(5*4) = 2*20 = 40
Answer:
Step-by-step explanation:
To find the area, I divided the shape into squares and rectangles. Then, I found the area of the squares and rectangles and added them,
- Area = (7 x 7) + (18 x 5) + (6 x 4)
- => (49) + (90) + (24)
- => 163 in²
Hence, the area is 163 in.²
Using the binomial distribution, it is found that there is a 0.125 = 12.5% probability of observing exactly 3 tails.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, considering 3 tosses of a fair coin, the parameters are n = 3 and p = 0.5.
The probability of 3 tails is P(X = 3), hence:
0.125 = 12.5% probability of observing exactly 3 tails.

Answer:
both linear and nonlinear
Answer:
225 necklaces.
Step-by-step explanation:
Assuming that they have the necessary amount of straws to match the beads then we can use the following simple equation to solve this problem.
t = b/12 ... where t is the total amount of necklaces and b is the number of beads you have
t = 2700 / 12
225 necklaces.
For 225 necklaces you would also need 1125 straws since each necklace requires 5 straws to be fully made. Therefore if you have this amount you should not run into any problems.
