Step-by-step explanation:
The probability that it will rain on wednesday will be 0.75.
What is a expression? What is a mathematical equation? What is Probability?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. The formula to calculate the probability of occurrence of an event 'A' can be written as -
P(A) = n(A)/n(S)
where -
n(A) = Number of outcomes favorable to event A.
n(S) = Total number of outcomes.
We have a meteorologist who says that there is a 50% greater chance of rain than no rain on Wednesday.
Assume that the probability that it will rain on wednesday be [x]. Now, we can write -
P[R] = P[N.R.] + 1/2
P[R] + P[R] = P[N.R.] + P[R] + 1/2
2 P[R] = 1 + 1/2
2 P[R] = 1.5
P[R] = 1.5/2
P[R] = 0.75
Therefore, the probability that it will rain on wednesday will be 0.75.

An angle 0 is drawn on the unit circle such that its terminal ray is in the second quadrant.
if sin 0 = 0.809, then what must be true about sin(-0)?
Answer:
sin(-θ) = -0.809
Step-by-step explanation:
To find this, simply perform the operation that is being asked, make theta negative.
If you want to find out what theta is in the first place, do this:
θ = arcsin(0.809)
θ = 54
Then to find sin of negative theta, substitute:
sin(-θ), or, sin(-54)
should equal to:
sin(-θ) = -0.809

We see the triangle ABC and AED with common vertex at the point A.
1. The center of dilation is the point A as it remains unchanged after dilation and the other vertices are lined up with the point A.
2. Since the scale factor is 1/2 < 1, the dilation is a smaller triangle, which is AED

Answer:
1, 3, 5
Step-by-step explanation:
let the 3 consecutive odd numbers be n , n + 2 , n + 4 , then
5(n + 2) = 2(n + n + 4) + 3 ( 5 times 2nd = twice sum of 1st and 3rd + 3 )
5n + 10 = 2(2n + 4) + 3
5n + 10 = 4n + 8 + 3
5n + 10 = 4n + 11 ( subtract 4n from both sides )
n + 10 = 11 ( subtract 10 from both sides )
n = 1
n + 2 = 1 + 2 = 3
n + 4 = 1 + 4 = 5
The 3 consecutive odd numbers are 1, 3, 5
Step-by-step explanation:
let the three consecutive odd number be x + 1 , x + 3 , x + 5
a/q
5 times the middle number = 5(x + 3) is
3 more than twice the sum of 1st and 3rd number = 3 + 2(x+1 + x + 5 )
so,
= 5 ( x + 3 ) = 3 + 2 ( x + 1 + x + 5 )
= 5x + 15 = 3 + 4x + 12
= 5x + 15 = 4x + 15
= -4x + 5x = 15 - 15 = 0
= x = 0
so, the 3 consecutive odd numbers are,
x + 1 = 1
x + 3 = 3
x + 5 = 5
and also a/q
5 times the middle number = 5×3 = 15
is equal to 3 more than twice the sum of 1st and 3rd number = 3 + 2(1+5) = 12 + 3 = 15
LHS = RHS
hope this answer helps you dear...take care and may u have a great day ahead!

factor the expressions
x^3 + x^2 -2x^2 +2x=3x-3
factor the expression
-x^2 x (x-1)-2x x (x-1) +3 (x-1)
rewrite the expression
-(x-1) x (x^2 + 2x-3)
rewrite
-(x-1) x (x^2 + 3x - x - 3)
factor the expression
-(x-1) x (x^2+2x-3)
factor the expression
-(x-1) x (x x(x+3)-(x+3)
write in exponential form

4(x-8)+12 equal 2(2x-9)
(Answer explained)
4(x-8)+12=2(2x-9)
We move all terms to the left:
4(x-8)+12-(2(2x-9))=0
We multiply parentheses
4x-(2(2x-9))-32+12=0
We calculate terms in parentheses: -(2(2x-9)), so:
2(2x-9)
We multiply parentheses
4x-18
Back to the equation:
-(4x-18)
We add all the numbers together, and all the variables
4x-(4x-18)-20=0
We get rid of parentheses
4x-4x+18-20=0
We add all the numbers together, and all the variables
-2!=0

A line that passes through the point (x,y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx + b.
A line is drawn on the coordinate plane that passes through the point (3,-6) and has a slope of 4. The y-intercept of the line is
Answer:
y-intercept is -18
Step-by-step explanation:
The total y=mx+b equation is y=4x-18, you can check in a calculator. I checked on a graphing calculator, and solved it via graphing on a piece of paper.
A line is drawn on the coordinate plane that passes through the point (3,-6) and has a slope of 4. The y-intercept of the line is -18.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
Given:
A line that passes through the point (x, y), with a y-intercept of b and a slope of m, can be represented by the equation,
y = mx + b.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = 4 (given)
So, the equation of the line is,
y - y₁ = m(x - x₁) equation 1
And here
x₁ = 3 and y₁ = -6.
Substituting the values to the equation 1,
y - (-6) = 4 (x - 3)
y+6 = 4x -12
y = 4x -18.
Comparing with the slope-intercept form,
we get y-intercept b = -18
Therefore, the equation is y = 4x -18 and y -intercept of the equation is -18
