Here is the answer the app is called cymath btw
Let's attack this problem using the z-score concept. The sample std. dev. here is (0.25 oz)/sqrt(40), or 0.040. Thus, the z score representing 3.9 oz. is
3.9 - 4.0
z = -------------- = -2.5
0.040
In one way or another we must find the area under the std. normal curve that lies to the left of z = -2.5. Use a table of z-scores or a calculator with built-in statistics functions. According to my TI-83 Plus calculator, that area is
0.006. One way of interpreting this that with so small a standard deviation, most volumes of coffee put into the jars are very close to the mean, 4 oz.
Answer:
I think The White one is 3.61 and the purple is 10....
Step-by-step explanation:
we just divide the shapes into separate and find the area of each separate shape
Answer:
I attached a picture below of what the lines of symmetry are.
Answer:
4240 inches²
Step-by-step explanation:
In order to find the amount of film needed, we have to find the surface area of this cuboid.
- Formula to Find Surface Area of Cuboid:
, where w = width, l = length, and h = height.
Now, let's solve!
Therefore, the answer is 4240 inches².
