Find the probability P(E or F) if E and F are mutually exclusive, P(E)=0.41 and P(F) = 0.47
P(E or F) =
Answer:
P(E or F)=P(E)+P(F)=0.41+0.47=0.88
As per the probability of an event, the probability P(E or F) is 0.88, when E and F are mutually exclusive.
What is probability of an event?"Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes how likely they are.
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. "
Given, the probability of the event E is P(E) = 0.41
The probability of the event F is P(F) = 0.47
Now, the probability P(E or F) is
= P(E) + P(F)
= 0.41 + 0.47
= 0.88
Therefore, P(E or F) = 0.88

What is the equation for the line in slope-intercept form?
Enter your answer in the box.
Answer:
y = -2x - 4
Step-by-step explanation:
In order to write down the equation of this line in slope-intercept form we will need to know the slope and the y intercept. Since the y intercept is the value of y when x = 0, from this we know that in our case the y intercept is - 4. Now in order of find the slope we can choose any two points on the linear function and then divide the rise by the run of the slope (if you want to understand this more you can read about how to find the slope). In our case I took two points (-2, 0) and (0, -4). Form here we know that the slope is....
Let "m" be the slope...
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1} }= \frac{-4 - 0}{0 + 2} = \frac{-4}{2} = -2[/tex]
We know that the slope-intercept looks like y = mx + b (where m is the slope and b is the intercept) so since we know both the slope and the y interest we can conclude the following.
The equation of the linear function show is y = -2x - 4

Write the equation of the line that passes thought the points (0,4) and (-9, -3).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
The equation of the straight line in point-slope form
[tex]y - 4 = \frac{7}{9} (x-0)[/tex]
The equation of the straight line
7x -9y +36 =0
Step-by-step explanation:
Step(i):-
Given that the points (0,4) and (-9,-3)
The slope of the line
[tex]m = \frac{y_{2} - y_{1} }{x_{2}- x_{1} } = \frac{-3-4}{-9-0} = \frac{7}{9}[/tex]
Step(ii):-
Equation of the straight line passing through the point (0,4) and having slope m = 7/9
[tex]y - y_{1} = m (x-x_{1} )[/tex]
[tex]y - 4 = \frac{7}{9} (x-0)[/tex]
9 y - 36 = 7x
9y = 7x + 36
[tex]y = \frac{7x}{9} +\frac{36}{9}[/tex]
Slope - intercept form
[tex]y = \frac{7x}{9} +4[/tex]
Final answer:-
The equation of the straight line in point-slope form
[tex]y - 4 = \frac{7}{9} (x-0)[/tex]
The equation of the straight line
7x -9y +36 =0
what is -2(1-4x)=3x+8
Answer:
x = 2
Step-by-step explanation:
[tex]-2(1 - 4x) = 3x + 8[/tex]
[tex]=> -2 + 8x = 3x + 8[/tex]
Lets keep the variables in L.H.S .
[tex]=> 8x - 3x = 8 + 2[/tex]
[tex]=> 5x = 10[/tex]
[tex]=> x = \frac{10}{5} = 2[/tex]
Verification :-
Lets put x = 2 in the eqn.
In L.H.S -
[tex]-2 (1 - 4 \times 2)[/tex]
[tex]=> -2 (1 - 8)[/tex]
[tex]=> -2 \times -7[/tex]
[tex]=> 14[/tex]
In R.H.S -
[tex]3 \times 2 + 8[/tex]
[tex]=> 6 + 8[/tex]
[tex]=> 14[/tex]
∴ L.H.S. = R.H.S. (Proved)
5. An airplane takes 4 hr to travel a distance of 4100 km. Another airplane travels at a speed
which is 200 km/hr less than first airplane. How long will it take to travel the same distance by
the second airplane?
Answer:
4.969696 hours
Step-by-step explanation:
The distance traveled is shown through the following equations
Distance = velocity * time
This means that
4100=velocity*4
This means that ariplane 1 travles at 1025 km/hr
We can then subtract 200 from this to find that airplane two travels at a speed of 825 km/hr
Now we need to find how long it takes for that plane to travel 4100
So using the same equation
4100=825*time
Divison will tell us that the answer is around 4.9696 hours which is pretty much 5

A triangle has side lengths of n, n – 3, and 2(n − 2). If the perimeter of the triangle is at least 37 units, what is the value of n?
OA.
n> 11
OB
n> 8
O C.
n > 10.5
OD
n > 7.5
Answer:
n = 11
Step-by-step explanation:
The side length of a triangle are n,n-3 and 2(n-2).
The perimeter of the triangle, P = 37 units
We need to find the value of n.
Perimeter = sum of all sides
n+n-3 +2(n-2) = 37
2n-3+2n-4 = 37
4n -7 = 37
4n = 37+7
4n = 44
n = 11
So, the value of n is 11.

Linnett is planning a concert and needs to tell the bands that are playing how big the stage is. The stage has a width of 32 ft. And a depth of 17 ft. What is the area of the triangular stage below, in square feet?
Answer:
272 ft²
Step-by-step explanation:
Given that:
Width = 32 = length of base ; depth = 17 = height
Area of triangle :
A = 0.5 * base * height
A = 0.5 * 17 * 32
A = 272 ft²
Area of triangular stage = 272 ft²
expand quadratic equation (2x-3)(x+4) = 0
Answer:
Step-by-step explanation:
Simplifying
(2x + -3)(x + -4) = 0
Reorder the terms:
(-3 + 2x)(x + -4) = 0
Reorder the terms:
(-3 + 2x)(-4 + x) = 0
Multiply (-3 + 2x) * (-4 + x)
(-3(-4 + x) + 2x * (-4 + x)) = 0
((-4 * -3 + x * -3) + 2x * (-4 + x)) = 0
((12 + -3x) + 2x * (-4 + x)) = 0
(12 + -3x + (-4 * 2x + x * 2x)) = 0
(12 + -3x + (-8x + 2x2)) = 0
Combine like terms: -3x + -8x = -11x
(12 + -11x + 2x2) = 0
Solving
12 + -11x + 2x2 = 0
Solving for variable 'x'.

Set the factor '(3 + -2x)' equal to zero and attempt to solve:
Simplifying
3 + -2x = 0
Solving
3 + -2x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -2x = 0 + -3
Combine like terms: 3 + -3 = 0
0 + -2x = 0 + -3
-2x = 0 + -3
Combine like terms: 0 + -3 = -3
-2x = -3
Divide each side by '-2'.
x = 1.5
Simplifying
x = 1.5
Subproblem 2
Set the factor '(4 + -1x)' equal to zero and attempt to solve:
Simplifying
4 + -1x = 0
Solving
4 + -1x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + -1x = 0 + -4
Combine like terms: 4 + -4 = 0
0 + -1x = 0 + -4
-1x = 0 + -4
Combine like terms: 0 + -4 = -4
-1x = -4
Divide each side by '-1'.
x = 4
Simplifying
x = 4
Solution
x = {1.5, 4}

Step-by-step explanation:
Given
[tex]x^2 - 12x = 21[/tex]
Required
Make a perfect square
First, get the coefficient (k) of x
[tex]k = -12[/tex]
Divide by 2
[tex]\frac{k}{2} = \frac{-12}{2}[/tex]
[tex]\frac{k}{2} = -6[/tex]
Square this result:
[tex](\frac{k}{2})^2 = (-6)^2[/tex]
[tex](\frac{k}{2})^2 = 36[/tex]
Hence, 36 when added to the left-hand side makes it a perfect square trinomial

Nuestro presupuesto es S/ 400 y acordamos distribuirlos así con tu mamá: 25 % en verduras, 15 % en lácteos, 30 % en menestras, 20 % en frutas y el resto en artículos de limpieza. ¿Podrías ayudarnos diciéndonos cuánto dinero utilizaremos para cada cosa? 1
Answer:
Verduras= $100
Lacteos= $60
Menestras= $120
Frutas y verduras= $80
Limpieza= $40
Step-by-step explanation:
Presupuesto= $400
Primero determinamos la proporción a gastar en cada rubro:
Verduras= 0.25
Lacteos= 0.15
Menestras= 0.3
Frutas y verduras= 0.2
Total= 0.9
Limpieza= (1 - 0.9) = 0.1
Ahora, la cantidad de dinero:
Verduras= 0.25*400= $100
Lacteos= 0.15*400= $60
Menestras= 0.3*400= $120
Frutas y verduras= 0.2*400= $80
Limpieza= 0.1*400= $40
Total= $400
