The mean of the weight is 8.1 ounces.
So the means of the distribution of 10 sample will be 10*8.1.
And the mean of 20 <span>cheese wedges is again 20*8.1.
(The mean of the addition of two normal law is the sum of the
mean of each law)
Divide the above two numbers: </span>
The distribution of the sample means of the weights of cheese wedges is multiplied by 2 in the new <span>
batches</span>
.

Step-by-step explanation:
Answer:
r = 0.5 and 5.25
Step-by-step explanation:
The common ratio r of a geometric progression is the ratio of a term to the one before it, that is
(a)
r = 42 ÷ 84 = 0.5
(b)
To obtain a term in the sequence multiply the previous term by r, thus
a₅ = 10.5 × 0.5 = 5.25
Answer:
1) You know that the addition of all interior angles of a triangle always should add up to 180°
Then, for example, we can construct a triangle with angles
100°, 40°, 40° such that
100° + 40° + 40° = 180°
So we have an example of a triangle that has one angle greater than 90°.
2) Suppose that we have the positive numbers 0.5 and 1.
The product is: P = 0.5*1 = 0.5
the sum is: S = 0.5 + 1 = 1.5
The sum is greater than the product.
A= pi • r•r =
A = pi • 10• 10
