The statement “If the movement of a mass on a spring may be
modeled with simple harmonic motion, then its frequency decreases with time”
is false.
<span>In mechanics and physics, simple </span><span>harmonic motion </span>is a type of
periodic motion<span> or oscillation </span><span>motion </span>where the restoring force is directly proportional to
the displacement and acts in the direction opposite to that of displacement .
5x + 3y= 8.50
3x + 2y= 5.25
Lydia is the first equation. She bought 5 pounds of apples which is x and bought 3 pounds of bananas which is y. Basically, remember each banana and apple weighs a price per pound. We don't know the price so we just put an x. This is the same for the second equation
Answer:
Part a) The scale of the new blueprint is 
Part b) The width of the living room in the new blueprint is 
Step-by-step explanation:
we know that
The scale of the original blueprint is
and
the width of the living room on the original blueprint is 6 inches
so
<em>Find the actual width of the living room, using proportion</em>
<em>Find the actual length of the living room, using proportion</em>
<em>Find the scale of the new blueprint</em>, divide the length of the living room on the new blueprint by the actual length of the living room
simplify
<em>Find the width of the living room in the new blueprint, using proportion</em>
Answer:
75% students read less than 35 pages.
Step-by-step explanation:
The stem and leaf plot is given below
0 | 5 0 5 8
1 | 2 3 5 8 8 9
2 | 2 4 6 7 7 7
3 | 3 5 6
4 | 2 4 6
5 | 7
Count the students in each row.
Row 1 = 4 students
Row 2 = 6 students
Row 3 = 6 students
Row 4 = 3 students
Row 5 = 3 students
Row 6 = 1 student
Total students = 23 students
75% of 23 students = 0.75/100 · 23 = 12.25 students
75% of 23 students ≅ 17 students
From the stem and leaf plot, 17th student read 33 pages while 18th student reads 35 pages.
Which means
75% students read less than or equal to 33 pages.
OR
75% students read less than 35 pages
