Answer:
102-105
Step-by-step explanation:
Median formula for a group data is expressed as shown;
Median = (N+1)/2 th value/interval
N is the total number of students
From the question N = 36
Median = (36+1)/2
Median = 37/2
Median = 18.5
Therefore we are to cumulate the value of the frequency up till the 18.5th value.
From the table
If we keep cummulating the frequency from the top;
Let's add:
1+3+5+5+8 = 21
Since the 18.5th values falls within the cumulative frequency value (i.e 21), the corresponding interval where we stopped cumulating will be our Median.
From the table, the interval with the frequency of 8 is 102 - 105. Hence the median is located at the interval 102 - 105

Answer: Second company (in the table), aka #1 toys, produces at a slower rate
============================================================
Explanation:
The equation y = 123x is in the form y = mx+b with m = 123 as the slope. The slope is the rate of change telling us how many toys per minute are produced. In this case, 123 toys per minute is the rate for the first company.
----------
We'll need the slope of the other function. So we need to pick two rows from the table and use the slope formula. I'll pick the first two rows.
m = (y2-y1)/(x2-x1)
m = (1320-600)/(11-5)
m = 720/6
m = 120
The second company produces at a rate of 120 toys per minute. This is the smaller rate, so this company produces at a slower speed.

- A quadratic model for a certain stock on Wall Street is P=-3d2 + 50d, where d
represents the days of trading and P is the price per share.
a. What is the maximum price per share of the stock?
Help please I’m stuck
Answer:
208.333
Step-by-step explanation:
A quadratic model for a certain stock on Wall Street is given by :
[tex]P=-3d^2+50d[/tex] ...(1)
(a) We need to find the maximum price per share of the stock. For maximum value, put :
[tex]\dfrac{dP}{dd}=0[/tex]
[tex]\dfrac{d(-3d^2+50d)}{dd}=0\\\\-6d+50=0\\\\d=\dfrac{50}{6}\\\\d=8.34[/tex]
price per share of the stock is maximum when the value of d = 8.34. Put the value of d in equation (1).
[tex]P=-3(8.34)^2+50(8.34)\\\\P=208.333[/tex]
So, the maximum price per share of the stock is 208.333.

Matt is going to sign up for the "Fruit of the Month Club." He must pay a $25 enrollment fee, as well as $17 each month to continue his membership. He is going to stop receiving fruit once he has spent $280. Write the equation of this problem in Slope-Intercept form (hint: y=mx+b): How much as he spent on fruit after 5 months? In how many months until he has spent $280?
Answer:
He spent on fruit after 5 months is $110.
In 15 months he spent $280.
Step-by-step explanation:
Fixed pay for membership is $25
And enrollment fee is $17 for each month.
The equation represents this situation is
y= 17 x + 25
He is going to stop receiving fruits once he spent $280.
Now, to find how much he spent on fruit after 5 months is plugin x as 5 into
y=17x+25 for x
y=17(5)+25
y=85+25
y=110 dollars
Now, to find how many months until $280 is to plug in y as 280 then solve the equation for x.
280 = 17 x+25
Subtract both sides 25
255 =17 x
Divide both sides by 17
x= 15 months

Prove that in any triangle the length of a side is less than the half of the perimeter in statement reason format.
Answer:
Proved
Step-by-step explanation:
I am going to pose c as the largest side in a random triangle
If so then remember that, by the triangle inequality, a + b > c. Let's start from there...
Statement: | Reasoning:
1. a + b > c 1. Triangle Inequality
2. a + b + c > c + c (adding c on both sides), 2. Algebra + Def. Of Perimeter
a + b + c > 2c (simplified)
Perimeter > 2c (definition of perimeter)
c < 1/2 * Perimeter
The prove of statement ''in any triangle the length of a side is less than the half of the perimeter'' is shown.
What is Perimeter?
The sum of all sides of a quadrilateral is called a perimeter.
Given that;
The statement is,
''In any triangle the length of a side is less than the half of the perimeter''.
Now,
Let sides of triangles are a, b and c.
The triangle inequality is;
a + b > c
Add both side by c;
a + b + c > c + c
a + b + c > 2c .... (i)
Since, Perimeter of a triangle with sides a, b and c is;
Perimeter (P) = a + b + c
Substitute value of perimeter in equation (i), we get;
a + b + c > 2c
P > 2c
c < P/2
Thus, In any triangle the length of a side is less than the half of the perimeter.

Step-by-step explanation:
In the adjoining figure , AB = 6 , BC = 8 , [tex] \angle[/tex] ABC = 90° , BD ⊥ AC and [tex] \angle[/tex] ABD = [tex] \theta[/tex] , find the value of sin [tex] \theta[/tex].
Here we are given with a triangle with smaller triangles formed due to the altitude on AC. Given:
AB = 6BC = 8<ABC = 90°BD ⊥ AC<ABD = [tex] \theta[/tex]We have to find the value for sin [tex] \theta[/tex]
So, Let's start solving....
In ∆ADB and ∆ABC,
<A = <A (common)<ABC = <ADB (90°)So, ∆ADB ~ ∆ABC (By AA similarity)
The corresponding sides will be:
[tex] \sf{ \dfrac{AD}{AB} = \dfrac{AB}{AC} }[/tex]
We know the value of AB and to find AC, we can use Pythagoras theoram that is:
AC = √6² + 8²
AC = 10
Coming back to the relation,
[tex] \sf{ \dfrac{AD}{6} = \dfrac{6}{10} }[/tex]
[tex] \sf{AD = \dfrac{6 \times 6}{10} = 3.6}[/tex]
In ∆ADB, we have to find sin [tex] \theta[/tex] which is given by perpendicular/base:
[tex] \sf{\sin( \theta) = \dfrac{AD}{AB} }[/tex]
Plugging the values of AD and AB,
[tex] \sf{\sin( \theta) = \dfrac{3.6}{6} }[/tex]
Simplifying,
[tex] \sf{ \sin( \theta) = \dfrac{3}{5} = \boxed{ \red{0.6}}}[/tex]
And this is our final answer.....

In golf, a golfer must have a score of 0 in order to be at par. A golfer scores 4 above par on the first hole, 3 below par on the second hole, and 1 below par on the third hole. Write an expression to solve for their score. What is the golfer's score?
Answer:
The expression to solve the golfer's score is X = A + B + C
The golfer's score is 0 (The golfer is at par)
Step-by-step explanation:
The given information are;
The score the golfer must have = 0
The score, A, the golfer has on the first hole = +4
The score. B, the golfer has on the second hole = -3
The score. C, the golfer has on the third hole = -1
Therefore, the expression to calculate the golfer's score, X, is given as follows;
The golfer's score = The score the golfer has on the first hole + The score the golfer has on the second hole + The score the golfer has on the third hole
The expression to solve the golfer's score is given as follows;
X = A + B + C
The golfer's score = 4 - 3 - 1 = 0
The golfer's score = 0.

Answer:
y = 3
Step-by-step explanation:

- 7y = - 21 ( divide both sides by - 7 )
y = 3
Answer:
[tex]y=3[/tex]
Step-by-step explanation:
[tex]-7y - 17 = -38[/tex]
Add 17 both sides
[tex]-7y - 17 + 17= -38+17[/tex]
[tex]7y= -21[/tex]

The perimeter of a rectangle is 64 feet. The length of the rectangle is 3 times the width of the rectangle. If w represents the width of the rectangle, the equation that represents the perimeter is 2 (3 w) + 2 w = 64. Which shows the first step that should be taken to verify that the width of the rectangle is 8? A regular hexagon and a rectangle have the same perimeter, P. A side of the hexagon is 4 less than the length, l, of the rectangle. The width of the rectangle, w, is 2 less than the length of the rectangle. What is the perimeter of the hexagon?
Step-by-step explanation:
given the perimeter is
64ft
the length l= 3w
we know that the perimeter of a rectangle is given as
P=2l+2W
but L=3w
64=2(3w)+2w
64=6w+2w
64=8w
divide both sides by 8 we have
w=64/8
w=8ft
also
let the lenght of the rectangle be l
side of hexagon=l-4
perimeter of hexagon
P=5(l-4)
P=5l-20
width of rectangle w=l-2
perimeter of rectangle= 2l+2w
but w=l-2
5l-20= 2l+2(l-2)
5l-20=2l+2l-4
5l-20=4l-4
5l-4l=-4+20
l=16ft
perimeter of hexagon
P=5(l-4)
put l=16
perimeter of hexagon
P=5(16-4)
p=5(12)
P=60ft
Answer: 2(3(8))+(2+8)=64 or c
Step-by-step explanation:
You have to replace w with 8 meaning 8 is now the width, therefore, c is the correct answer.
