Answer:
Both.
Step-by-step explanation:
The perimeter of a trapezuun is given by : a + b + c + d ; where a, b, c, d are the lengtb of the sides of the trapezium.
The perimeter of the trapezium Given below is :
(4 + 6 + 4 + w + 2)
Evaluating both expressions :
Peter = 6 + 4 + (w + 2) + 4
Christine's expression = w + 16
From the expression, we can see that Peter's expression is correct s he wrote the sum of all the four sides
As for Christine's expression, it is also right ; as she added all the sides to obtain a reduced term
Hence, both are correct
<u>Given</u>:
The random number table was used to generate the random sample of dollar amounts. The samples are 7.43, 5.38, 6.39, 6.53, 4.72, 5.58, 3.63, 7.43, 5.29, 5.70
We need to determine the mean of the given random sample.
<u>Mean of the random sample:</u>
The mean of the random sample can be determined using the formula,
Substituting the values, we have;
Rounding off to the neatest hundredth, we get;
Therefore, the mean of the random sample is 5.81
Hence, Option B is the correct answer.
