You roll a 6-sided die.
What is P(odd)?
i need someone to explain this to me please.
Write your answer as a percentage.
Answer:
50%
Step-by-step explanation:
In total, there are six things that can happen when you roll a 6-sided die: you either roll a 1, 2, 3, 4, 5 or a 6.
Three of these numbers are odd, therefore meaning the chances of you rolling an odd number is [tex]\frac{3}{6}[/tex] (because there are 6 events which could occur, 3 of which are odd)
Converting this into a fraction can be made easier by simplifying the fraction. As both the numerator and denominator can be divided by 3, you can simplify the fraction to [tex]\frac{1}{2}[/tex]
To turn this into a percentage, first divide 100% by your denominator (2) to get 50%, and then multiply it by your numerator (1). Therefore, P(odd) is 50%.

What is the vertex of the graph of the following equation? y = x^2 + 2x-3
Answer:
vertex = (- 1, - 4 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = x² + 2x - 3 ← is in standard form
with a = 1, b = 2 , then
x = - [tex]\frac{2}{2}[/tex] = - 1
Substitute x = - 1 into the equation for corresponding value of y
y = (- 1)² + 2(- 1) - 3 = 1 - 2 - 3 = - 4
vertex = (- 1, - 4 )
what would be the equation for this graph? (WILL GIVE BRAINLEIST!)
Answer:
y = (x - 2)² - 9 Vertex form
y = x² - 4x - 5 Standard form
Step-by-step explanation:
vertex = (h, k) = (2, -9)
Vertex form
y = a(x - h)² + k
y = a(x - 2)² - 9
find "a" using point (5, 0)
0 = a(5 - 2)² - 9
0 = a(3)² - 9
0 = 9a - 9
9 = 9a
a = 1
y = (x - 2)² - 9
Standard form
y = (x² - 4x + 4) - 9
y = x² - 4x - 5

Answer: 57 degrees
Step-by-step explanation:
Angle ZXY = Angle YZV = 75 degrees (Alternate segment theorem)
Since angles on a straight line add upto 180 degrees:
Angle UZX = 180 - ( 75 + 48) = 57 degrees
Note: 75 is Angle YZV and 48 is Angle XZY

Find xy if x + y=3, x^2 + y^2 = 5
Answer:
mark me
Step-by-step explanation:
x+y=3
x=3-y
putting the value of x
in this
x²+y²=5
(3-y) ²+y²=5
9-6y+y²+y²=5
2y²-6y+9-5=0
2y²-6y+4=0
2y²-4y-2y+4=0
2y(y-2)-2(y-2)=0
(2y-2) (y-2) =0
2y-2=0 or y-2=0
y=1 or y=2
so x=2 or 1
so x×y=2×1 or 1×2=2

99% + 99% - 99% x 99% ÷ 99%
Answer:
0.99
Step-by-step explanation:
99% + 99% - 99% × 99% ÷ 99%
Add 99% and 99%198% + 99% - 99% × 99% ÷ 99%
Divide 99% × 99% by 99%198% - 99%
Subtract 99% from 198%99%
By defination :- p% = p / 100so, 99 / 100
= 0.99
Answer:
0.99
Step-by-step explanation:
99% + 99% - 99% × 99% ÷ 99%
Add 99% and 99%
198% + 99% - 99% × 99% ÷ 99%
Divide 99% × 99% by 99%
198% - 99%
Subtract 99% from 198%
99%
By defination :- p% = p / 100
so, 99 / 100
= 0.99

Answer:
11.9
Step-by-step explanation:
in maths, we are aware that in triangles we can use sine, cosine, and tangent.
using tangent, we have
tan 29⁰=6.6/x
and tan 29⁰=0.5543
0.5543=6.6/x
cross multiply
0.5543x=6.6
x= 6.6/0.5543
x= 11.9

A line goes through the points (8,9) and (-2,4)
(B) Write the equation of the line in point-slope form. Show your work.
Please only answer if you know the answer.
Please explain. :)
Answer:
[tex]\displaystyle y-9=\frac{1}{2}(x-8)\text{ or } y-4=\frac{1}{2}(x+2)[/tex]
Step-by-step explanation:
Point-slope form is given by:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
Where (x₁, y₁) is a point and m is the slope.
So, first, we will find the slope using the two points (8, 9) and (-2, 4). We can use the slope formula:
[tex]\displaystyle m=\frac{\Delta y}{\Delta x}=\frac{4-9}{-2-8}=\frac{-5}{-10}=\frac{1}{2}[/tex]
Next, pick either of the two points and substitute it into the point-slope formula. Using (8, 9), we acquire:
[tex]\displaystyle y-9=\frac{1}{2}\left(x-8\right)[/tex]
And using (-2, 4), we acquire:
[tex]\displaystyle y-4=\frac{1}{2}\left(x -(-2)\right)\Rightarrow y-4=\frac{1}{2}\left(x+2\right)[/tex]
Both of these are valid answers.
Answer:
y-9=1/2(x-8)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-9)/(-2-8)
m=-5/-10
m=1/2
y-y1=m(x-x1)
y-9=1/2(x-8)

for question 1
there can only be 36 outcomes so you find out how many time you could get 7and2 which is 8 from so u write 8.36=.2222
for question 2
divide the outcome by the total out comes example(there are 6 red balls and 4 white out of 15 so you do 10/15=.6667)
Answer:
#1Outcomes with sum of 7:
1 + 6, 2 + 5, 3 + 4, 4 +3. 5 + 2, 6 + 1Outcomes with sum of 11:
5 + 6, 6 + 5Total outcomes:
6*6 = 36Required probability:

Find the discriminant for each quadratic function below. Then list the number of zeros/solutions for each quadratic function.
1) 4x^2+10x-16=0
Discriminant________
Number of Zeros__________
2) -16x^2-7x+3=0
Discriminant_______
Number of zeros_________
Answer:
Step-by-step explanation:
The discriminant is found in
[tex]b^2-4ac[/tex] which is part of the quadratic formula. In
[tex]4x^2+10x-16=0[/tex], a = 4, b = 10, c = -16. Filling in for the discriminant:
[tex]10^2-4(4)(-16)=100+256=356[/tex]
It's positive so we know we have real roots; it's not a perfect square, so our solutions are 2 complex rational.
In [tex]-16x^2-7x+3=0[/tex], a = -16, b = -7, c = 3. Filling in for the discriminant:
[tex](-7)^2-4(-16)(3)=49+192=241[/tex]
It's positive and not a perfect square so the 2 solutions are complex rational
