Students in a math class recorded the number of text messages they received the previous day. how many students received at leas
1 answer:
Answer:
14 students
Step-by-step explanation:
You didn't include a graph, so I looked up the question to find the graph you are likely talking about.
If this graph does not match, ignore my answer (although the question is exactly the same so I'm guessing it might be the same)
{even if different , conceptually, here is what you do: }
Receiving at least 10 messages includes those who receive 10 messages.
Each X represents 1 student. So, 3 students received exactly 10 messages.
3 (who received 10)
2 (who received 15)
4 (who received 20)
5 (who received 25)
+________
14 students
14 students received ≥ 10 messages
(≥ means greater than or equal to,
< is less than (less < more)
> is greater than (more > less)
the line under includes the value _ (same or more ≥ than this value ; same or less ≤ than this value)
hope this helps you !!

Answer:
<em>The required points of the given line segment are ( - 1, - 5 ).</em>
Step-by-step explanation:
Given that the line segment AB whose midpoint M is ( 3, -2 ) and point A is ( 7, - 9), then we have to find point B of the line segment AB -
As we know that-
If a line segment AB is with endpoints ( ) and (
)then the mid points M are-
<em>M = ( ,
)</em>
Here,
<em>Let A ( 7, - 9 ), B ( x, y ) with midpoint M ( 3, - 2 ) -</em>
then by the midpoint formula M are-
<em>( 3, - 2 ) = ( ,
)</em>
On comparing x coordinate and y coordinate -
We get,
<em>( = 3 ,
= - 2)</em>
<em>( 7 + x = 6, - 9 + y = - 4 )</em>
<em>( x = 6 - 7, y = - 4 + 9 )</em>
<em>( x = - 1, y = -5 )</em>
<em>Hence the required points A are ( - 1, - 5 ).</em>
<em>We can also verify by putting these points into Midpoint formula.</em>
