Answer: Second option.
Step-by-step explanation:
For this exercise it is important to remember that, by definition, a "Cross section" is the two-dimensional shape obtained by the intersection of a three-dimensional body with a plane.
In this case you can observe in the figure given in the exercise, that the the cylinder (which is the three dimensional body) is sliced perpendicular to its base.
By definition , when a plane intersects a cylinder perpendicular to its base, the resulting shape obtained is a Rectangle.
A Rectangle is defined as a quadrilateral whose opposite sides are parallel and have equal lengt. And each angle measures 90 degrees (Angles that measure 90 degrees are also called "Right angles").
To see this better, you can see the picture attached.
Answer:
b) Chemistry
Step-by-step explanation:
To compare both scored we need to standardize the scores using the following equation:
Where x is the score, m is the mean and s is the standard deviation. So, 82 on chemistry is equivalent to:
Because the mean of the scores on the chemistry final exam is equal to 75 and the standard deviation is 15
At the same way, 80 on Calculus is equivalent to:
Because the mean of the scores on the calculus final exam is equal to 83 and the standard deviation is 13
Now, we can compare the values. So, taking into account that -0.2308 is lower than 0.4667, we can said that the student do better in Chemistry.
Answer: The answer to the first question is C(20%)
Step-by-step explanation: 1. you need to find the absolute decrease which is subtracting 350-280= 70.
2. now you need to find the percent decrease which is dividing the absolute decrease by the whole price.. so.. 70/350= .20
3. now just multiply .20 *100 = 20%
The right answer for the question that is being asked and shown above is that: "C. The student incorrectly multiplied by the scale factor instead of adding it." .After a dilation with a center of (0, 0), a point was mapped as (1, 4) → (4, y). A student determined y to be 16.
The right answer for the question that is being asked and shown above is that: "C. <span>only 1."</span>
