cross section is formed by the <em>intersection</em> of a<em> three-dimensional object</em> and a <em>plane.</em>
So the right answers are 4 and 5. Let's explain each case.
First. A prism and a horizontal planeThe representation of this statement is shown in Figure 1. A prism has the following characteristics:
1. These objects have identical ends.
2. They have flat faces.
3. They have </span><span>the same </span>cross section<span> all along its length </span><span>
So in the figure, you can see how the horizontal plane intersects the prism. <em>The cross section</em> of this object <em>is a</em> <em>triangle</em>. Thus, </span><span>it has the same cross section all along its length and this object is called <em>a triangular prism.</em></span><span>
Second. A vertical plane and a pyramid
As shown in Figure 2 you can see the representation of this statement. </span><span>If the pyramid is cut with a plane that passes through the top vertex and it is perpendicular to the base, then the intersection of this pyramid and the plane becomes a <em>triangular cross section</em>.</span>
Based on the error rate of manually and electronically filed returns, the chances of making an error using manual instead of electronic is c. 400 times more likely.
<h3>How much more likely are errors with manual filing?</h3>
This can be found as:
= Percentage error from manual returns / Percentage error from electronic returns
Solving gives:
= 20% / 0.05%
= 400 times
In conclusion, option C is correct.

Answer:
38/5
Step-by-step explanation:
15 x 3 = 45 + 3 = 48/15
then 4 + 5 = 20 + 2 = 22/5
22/5 + 48/15 = ?
find the common denominator
15 ÷ by 3 so you do the same to the numerator so, 48 ÷ 3 = 16
then keep the 22 and 16 and put it as 16/5 and 22/5 and add them to get 38/5
hope this helps
Answer:
We need to solve each equation:
1. 2x - 5 = x
2x - x = 5
x = 5 ✅
2. -3b + 1 = 3b -5
5 + 1 = 3b + 3b
6 = 6b
b = 1 ✅
3. (1/2)t + 7 = (3/2)t - 4
t + 14 = 3t - 8
2t = 22
t = 11 ✅
4. -2.3 + 1.2x = 5.9 - 2.9x
2.9x + 1.2x = 5.9 + 2.3
4.1x = 8.2
x = 2 ✅
5. -7y -21 = -3y - 21
-21 + 21 = -3y + 7y
0 = 4y
y = 0 ✅
Answer:
Gerald will need to conduct fewer trials because experimental and theoretical results in experiments with small
numbers of possible outcomes are the same.
