Answer:
D. Obtain a cluster sample by randomly selecting 20 counties and visiting every restaurant within those counties.
Step-by-step explanation:
Since this executive wants to minimize cost and expenses he should use a cluster sample of 20 counties and using the selected counties as a representative of the whole. Cluster sampling is a good and useful way of doing market research. It is more economical than other sampling methods and as the executive cannot get information on the whole population, he would be able to get information from the clusters.
A) x * y = 196A) x = 196 / y
B) x + y = 35Substituting A) into B)
B) 196 / y + y = 35Multiplying both sides by y
B) 196 + y^2 = 35yB) y^2 -35y + 196 = 0
X1 = 28X2 = 7
She fill 12 bags because if you take 3/4*11 3/8- 1/8=12
Question:
Point T, the midpoint of segment RS, can be found using the formulas x = (1/2) (6 – 2) + 2 and y = (1/2) (4 – 6) + 6. What are the coordinates of point T?
Answer:
Step-by-step explanation:
Given
Required
Determine the coordinates of T
The coordinates of T can be represented as 
To do this, we simply solve for x and y
Solve 6 - 2
Solve 1/2 * 4
Solve 4 - 6
Solve 1/2 * -2
Hence, the coordinates of T(x,y) is:
So the rounded weights would be 3, 5, 2, 6, and 11, as when you round, you look at the number to the right of the one you want to round to. If it's 5 or larger, you add one to the spot you're rounding to, and make the rest of the numbers after into zeroes. If it's below 5, just change the ones after the one you want to round to into zeroes and don't add one.
Then for the estimating of the weight, you would add them together. 3+5+2+6+11. That would equal 27, so the estimate weight is 27 grams.
