The margin of error for a 95% confidence interval is 0.93.
mean (μ) = 23.4, standard deviation (σ) = 7.6, sample (n) = 254, confidence = 95% = 0.95
α = 1 - C = 1 - 0.95 = 0.05
α/2 = 0.05/2 = 0.025
The z score of α/2 is equal to the z score of 0.475 (0.5 - 0.025) which is equal to 1.96.
The margin of error (E) is given by:

Answer: y=1/2 - 3
Step-by-step explanation:
what they want you to find is the slope and y-intercept, and put that into slope-int form, which is y=mx+b. the point that is located on the y intercept is (0, -3), which gives you your b, which is -3. the other point on the graph helps you find the rise/run, or slope, which is m=2/4. simplified is m=1/2. so, y=1/2 - 3

On first week
Quantity of tomato = 25 tons
profit per ton = $250
So if she sells tomato on first week then total profit = 25 * 250 = $6250
On second week
Quantity of tomato =27 ton
profit per kg =$ 235
So if she sells tomato on second week then total profit =27* 235= $6345
On third week
Quantity of tomato = 29 ton
Profit per kg = $220
So if she sells tomato on third week then total profit = 29*220 = $6380
Now consider fourth week
Quantity of tomato =31 ton
Price per kg = $205
So if she sells tomato on fourth week then total profit =31*205 = $6355
so she must ship her tomatoes on third week i.e she will attain $ 6380 as profit.
Answer:
84.9
Step-by-step explanation:
The distance between first and third base makes the hypotonus of a triangle where the lengths of the legs are each 60 feet. To find the hypotonus, add (60)^2 + (60)^2 to get 3600 +3600 = 7200. Then square root 7200 to get the distance between first and third as 84.9
