Answer:
2/7
Step-by-step explanation:
Probabilty 1 = 4/7
Probability 2 = 3/6 = 1/2 (because if you not replace it, there is one less
final probability = 4/7 * 1/2 = 4/14 = 2/7

Find all Values of b that will make the polynomial a perfect square trinomial.
289r^2 - 102r + c
Please write out how to do this so I can see the steps of what I am doing wrong. thank you!
Answer:
10,404/334,084
Step-by-step explanation:
Given the polynomial
289r^2 - 102r + c
We are to find the value of c that will make it a perfect square
Divide through by 289
289r²/289 - 102r/289 + c/289
Half of the coefficient of r is 1/2(102/289)
Half of the coefficient of r = 102/578
Square the result
r² = (102/578)²
r² = 10,404/334,084
Hence the required constant is 10,404/334,084
What are the domain and the range of function ? f(x)=x-6/x^2-3x-18
Step-by-step explanation:
f(x)= (x-6) /(x²-3x-18)
=> (x-6) / (x-6)(x+3)
Domain = { x/ x≠6, x≠-3, x€R}
Range = { y/ y € R}
The domain and the range of function f(x)=x-6/x^2-3x-18 is x/ x≠6, x≠-3.
What are the domain and the range?The range of values in which we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's spectrum is the collection of values it may take as input. If we enter an x value, the function outputs this sequence of values.
Y = f is the formula to determine a function's range (x). It is only functioning in a link if each x value has exactly one y value.
f(x)= (x-6) /(x²-3x-18)
= (x-6) / (x-6)(x+3)
Domain = { x/ x≠6, x≠-3, x€R}
Range = { y/ y € R}

Finding the area of a triangle is stralghtforward if you know the length of the base and the helght of the triangle. But is it possible to
find the area of a triangle if you know only the coordinates of its vertices? In this task, you'll find out. Consider /_\ABC, whose vertices
are A(2, 1), B(3, 3), and C(1,6); let line segment AC represent the base of the triangle.
Part A
Find the equation of the line passing through B and perpendicular to AC.
Part B
Let the point of intersection of AC with the line you found in part A be point D. Find the coordinates of point B.

from 5 metres of cloth Alexa cut 217 cm how much cloth remaining after cutting
Answer:
2.83 meters
Step-by-step explanation:
Change 217 cm to meter
217 * 1 m/ 100 cm = 2.17 m
5 meter - 2.17 m = 2.83 meters
Answer:
283 cm Or 2.83 m of cloths remaining after cutting.
Step-by-step explanation:
Alexa have a cloth measures 5 metre and she cut 217 cm clothes.As we know that
1 m = 100 cm
so, 5 m = 5 × 100 = 500 cm
Alexa cut 217 cm of clothesSubtract 217 cm from 500 cm

In a two-digit number, the units digit is two more than the tens
digit. If you add the digits together and multiply the result by 6,
you will get five less than the number with the digits reversed.
Find the original number.
Answer:
35
Step-by-step explanation:
In a two-digit number, the units digit is two more than the tens
digit.
(10x) + (x + 2)
If you add the digits together and multiply the result by 6,
you will get five less than the number with the digits reversed.
(x + (x + 2))(6) = 10(x + 2) + x - 5
(2x + 2)(6) = (10x + 20)+ x - 5
12x + 12 = 11x + 15
x = 3
Original number
(10x) + (x + 2)
(10 * 3) + (3 + 2)

Remember - The formula to find out the area of a rectangle is l × w where l = length & w = width.Let the length of a rectangle be ' l ' . We're provided - Width ( w ) = l - 3 & area of rectangle ( A ) = 88 square inches. We're asked to find out the length and width of the rectangle.

Plug the values and then simplify :[tex] \large{ \text{⟶ \: 88 = l(l - 3)}}[/tex]
[tex] \large{ \bf{⟶ \: 88 = {l}^{2} - 3 l}}[/tex]
[tex] \large{ \bf{⟶ {l}^{2} - 3l = 88 }}[/tex]

The aspect ratio (the ratio of screen width to
height) of a rectangular flat-screen television is
16:9. The length of the diagonal of the screen
the television's screen 12c. Determine and wate. to
the nearest inch, the screen size (diagonal) of this
Mat-screen television
with a screen height of 20.6
inches
Answer:
[tex]Width = 36in[/tex]
[tex]Size = 42.02[/tex]
Step-by-step explanation:
Given
[tex]x \to width[/tex]
[tex]y \to height[/tex]
[tex]x : y = 16 : 9[/tex]
Required
The size of [tex]screen[/tex] of height [tex]20,6in[/tex]
First, we calculate the width using the following equivalent ratios
[tex]16: 9 = x : 20.6[/tex]
Express as fraction
[tex]\frac{16}{ 9} = \frac{x }{ 20.6}[/tex]
Solve for x
[tex]x = 20.6 * \frac{16}{ 9}[/tex]
[tex]x = 36.62[/tex]
Hence:
[tex]Width = 36in[/tex] --- approximated
So, we have:
[tex]x = 36.62[/tex]
[tex]y =20.6[/tex]
The size (diagonal) is then calculated using:
[tex]Size = \sqrt{x^2 + y^2[/tex]
[tex]Size = \sqrt{36.62^2 + 20.6^2[/tex]
[tex]Size = \sqrt{1765.3844[/tex]
[tex]Size = 42.02[/tex]
[tex]Size =42in[/tex] --- approximated

Answer:
y-1 = 3(x-2)
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y-1 = 3(x-2)

which of the following is the linear function?
1/3x=y-3
y=x^3+2
y=6x^2
y=2/3x
Answer:
1/3x=y-3, y=2/3x
Step-by-step explanation:
1/3x=y-3 is a linear function because there are no powers.
y=x^3+2 is not a linear function because x is squared by 3.
y=6x^2 is not a linear function because x is squared by 2.
y=2/3x is a linear function because there are no powers.

Hawkeye Elementary School is having a raffle for students who are in sports. The school leaders are voting to choose between the two options below.

If you get to vote and you have a daughter in sports, which option would you vote for and why?
Answer:
The answer is "0.052 and 0.056".
Step-by-step explanation:
For option 1:
Your daughter's opportunity (in sport) (when a person only wins once)
[tex]\to \frac{1}{39}+\frac{1}{38}\\\\ \to \frac{38+39}{1,482} \\\\\to \frac{38+39}{1,482} \\\\\to 0.052[/tex]
For option 2:
Your daughter would win a chance (in sport) [tex]= \frac{1}{18} = 0.056[/tex]
So a little better, the second option. The rationale is that there are fewer girls than boys so if a lottery in a smaller group is awarded you are more likely to win.
