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%.

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

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

A square has an area of 81 cm^2.What is the length of each side
Answer:
length of each side=√81
=9 cm
Answer:
9cm
Step-by-step explanation:
a square has 4 equal sides, so to find out the area you do width x height
the area is 81cm², which means that the side length is 9cm as 9 x 9 = 81

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 )

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

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:
X=60°
Y=50°
Step-by-step explanation:
Triangles must equal 180° when you add all angles together.
Triangle with angle X
50+70=120180-120=60X=60°To find the value of Y takes a few more steps, but it isn't hard!
Angle Y is on a line, which equals 180° just like a triangle.
We know X=60°, but we don't know what the blank angle equals.
We use the same steps as we did when finding X
60+50=110180-110=70Blank angle=70°We know that the blank angle=70° and that X=60°
Since the line equals 180, we add the two angles and then subtract from 180, just like before!
70+60=130180-130=50 Y=50°Solve the equation -8v – 5 = -21 for v.
Answer:
v=2
Step-by-step explanation:
add five to the other side and: -8v=(-21+5)
divide -16 by -8: v= -16/-8
v=2

The foundation of a house has 1200 termites. The termites grow at a rate of about 3% each day. How many termites are there after one week (round to the nearest termite?
Answer:
1476 termites after 7 days.
Step-by-step explanation:
initial population, P = 1200
rate of growth, r = 1.03
time, t = 7 days
Final population
= Pr^t
= 1200 (1.03^7)
= 1475.8
