An ogive graph serves as a graphical representation of the cumulative relative frequency distribution for quantitative variables. In other words, these graphs plot the percentile on the y-axis and the quantitative variable on the x-axis. An Ogive is connected to a point on the x-axis, that represents the actual upper limit of the last class, i.e.,( 80.5, 0) Take x-axis, 1 cm = 10 marks. Y-axis = 1 cm – 10 c.f. There are two types of ogives : Less than ogive : Plot the points with the upper limits of the class as abscissae and the corresponding less than cumulative frequencies as ordinates. Ogives are useful for determining the median, percentiles and five number summary of data. Remember that the median is simply the value in the middle when we order the data. A quartile is simply a quarter of the way from the beginning or the end of an ordered data set.

find the y-intercept of the parabola y=x^2-5x+9/2
Answer:
To find the Y-intercept substitute in 0 for all the x's and solve for Y
Your answer would be (0,9/2)
Steps:
Y=0^2-5(0)+9/2
0^2 -5(0)=0
Y=9/2
0 is your x place
and 9/2 is your Y intercept
Answer:
y-intercept = 9/2 or 4.5
Step-by-step explanation:
In the given quadratic equation, y = x² - 5x + 9/2, where:
a = 1, b = -5, and c = 9/2
The y-intercept is the point at which the parabola crosses the y-axis, and occurs at point (0, c ). It is the value of y when x = 0. To find out what I mean by this, we can substitute the value of x = 0 into the quadratic equation:
y = x² - 5x + 9/2
y = (0)² - 5(0) + 9/2
y = 0 - 0 + 9/2
y = 9/2
Therefore, the y-intercept (c) = 9/2, and has coordinates, (0, 9/2) or (0, 4.5).
Attached is a screenshot of the graph, where it shows the y-intercept.

Dan and Brian have played 51 tennis matches.
Dan has won 29 times.
Brian won the rest.
a) Estimate the probability that Dan wins.
b) Estimate the probability that Brian wins.
Answer:
A = 29/51 B = 22/51
Step-by-step explanation:
(E) = number of favorable outcomes/ total number of possible outcomes
- number of possible outcomes= 51
- number of favorable outcomes= 29
therefore, P(E) = 29/51
- number of possible outcomes= 51
- number of favourable outcomes = 51 - 29 = 22
therefore, P(E)= 22/51

If a fair coin is tossed twice the possible outcomes are HH, HT, TH or TT, where HH means both tosses are heads and HT means that the first toss is a head and the second toss is a tail, etc. Since the coin is fair, a 50-50 chance of getting a head or a tail, we assign a probability of 1/4 to each of the four outcomes. Assuming that a fair coin was tossed twice, find the probability that both tosses were heads given that at least one of the tosses was a head. Round your answer to 4 decimal places.
The conditional probability value rounded to 4 decimal places is : 0.2500
The relation can be used to find the conditional probability of events given :
P(HH | Atleast 1 head) = P(HHn(Atleast 1 H)) / P(Atleast 1 H)
P(Atleast 1 H) = P(HT + TH + HH)
P(Atleast 1 H) = P(HT + TH + HH) = 3(0.25) = 0.75
P(HHn(Atleast 1 H)) = P(HH) × P(Atleast 1 H) = 0.25 × 0.75 = 0.1875
Therefore, the conditional probability can be expressed as :
P(HH | Atleast 1 head) = 0.1875 / 0.75 = 0.25Therefore, P(HH | Atleast 1 head) is 0.25

medical and dental insurance. Medical coverage costs $9,560
a year and dental coverage costs $172 a year. The restaurant
pays 80% of the medical and 65% of the dental insurance. How
much is deducted each week for insurance
Out of the weekly amount that Shashi Rimoko makes, a deduction of $37.93 is made for insurance.
The total Medical cost is $9,560 and out of this, the amount paid by Shashi per year is:
= Amount x (1 - percentage paid by restaurant)
= 9,560 x ( 1 - 80%)
= $1,912
The amount he pays for Dental coverage is:
= Amount x (1 - percentage paid by restaurant)
= 172 x (1 - 65%)
= $60.20
The total amount he pays for insurance per year is:
= Medical + Dental
= 1,912 + 60.20
= $1,972.20
The weekly deduction is:
= Year amount / No. of weeks in year
= 1,972.20 / 52
= $37.93
In conclusion, $37.93 is deducted from his paycheck every week.

The area of a rectangle is 53 5/6 square feet the length of the garden is 9 1/2 feet what is the width (answer and equation please)
Answer:
The rectangle above shows its dimensions. Find the perimeter.
First, substitute the values for the width
(W)
and the length
(L)
into the perimeter formula.
P=2(12)+2(9)
Next, complete the multiplication and addition to find the perimeter.
PPP===2(12)+2(9)24+1842
The answer is 42.
The perimeter of the rectangle is 42 inches.
Area is the amount of square units inside the figure. Area is found by multiplying the
length×width
. The formula for finding the area of a rectangle is:
A=L×W
You can use the dimensions from the rectangle above to find the area of this rectangle.
First, fill the values for
L
and
W
into the formula for area.
AA==L×W12×9
Next, solve for the area by multiplying.
AA==12×9108
The answer is 108.
The area of the rectangle is
108 in2
.
Notice that the unit of measurement for area is squared. That is because you multiplied a unit measure times itself:
in×in=in2
. Area is always written in square units.
You can also find the perimeter and area of a square. Remember that a square has four equal sides given the symbol
s
. You can use the following formula for finding the perimeter of a square:
P=4s
Let’s look at an example.
A rectangle has a length of 12 feet and a perimeter of 72 feet. Write and solve an equation to determine the width of the rectangle.
First, substitute the values for the perimeter
(P)
and the length
(L)
into the perimeter formula.
72=2(12)+2W
Next, complete the multiplication.
72=24+2W
Then, subtract 24 from both sides to get your variable alone on the right side.
72−2448==24−24+2W2W
Then, multiply both sides by the reciprocal of 2 to isolate your variable.
12×481482W===12×2W1W24
The answer is 24.
The width of the rectangle is 24 feet.
The width of the rectangular garden is 5 2/3 feet
We have the following information available from the question is:
The area of a rectangle is 53 5/6 square feet
and, the length (L) of the garden is 9 1/2 feet
We have to find the width (W) of the rectangle.
Now, According to the question:
We know that :
The area of rectangle = L × W
Plug all the values in above formula:
53 5/6 = 9 1/2 × W
323/6 = 19/2 × W
[tex]W=\frac{323(2)}{6(19)}[/tex]
W = 17/3
17/3 as a mixed number would be 5 2/3.
Hence, The width of the rectangular garden is 5 2/3 feet

18. You have no more than $60 to spend. You want a drink that costs $1.50 including tax, and you want to buy a
pair of pants, which will have 4% sales tax.
a.) What is the inequality that represents the amount of money you have to spend?
b.) Given that you can spend no more than $60, what is the most a pair of pants could cost?
Answer:
a. pants + tax + drink ≤ 60 b. $56.16
Step-by-step explanation:
60-1.5 = 58.5 = money left for pants+tax
58.5/100 = 0.585 = 1%

A.(-18,-2)
B.(-10,-10)
C.(-9,-2)
D.(0,0)

Translation involves changing the position of a point in the coordinate plane.
The coordinate of the translated point A' is (D) (0,0)
The coordinate of the point is given as:
[tex]A = (-9,-1)[/tex]
The rule of translation 9 units right, and 1 unit up is:
[tex](x,y) \to (x+9,y+1)[/tex]
So, we have:
[tex]A' = (-9+9,-1+1)[/tex]
Simplify the expression
[tex]A' = (0,0)[/tex]
Hence, the coordinate of the translated point A' is (D) (0,0)
