Answer:
a. The probability of it not snowing on that particular day is 7/11
b. The probability of it not raining on that particular day is 5/8
Step-by-step explanation:
To answer this question, we need to understand something.
The probability of an event happening and the probability of that event not happening sums up to 1.
This will be our guiding principle in answering this question.
a. Probability of snowing on a given day = 4/11
Probability of not snowing = 1 - probability of snowing = 1-4/11 = 7/11
b. The probability of raining on a particular day = 3/8
The probability of it not raining on that particular day = 1-3/8 = 5/8

The height of a triangle is 2 less than 5 times it's base. If the base of the triangle is x feet, and the area of the triangle is 12 square feet, which equation models the situation
Answer:
Area A = 12 = 1/2 × x × (5x-2)
5x^2 - 2x -24 = 0
Solution;
Base x = 2.4
Height h = 10 ft
Step-by-step explanation:
Given;
base of the triangle is x feet;
Base = x
The height of a triangle is 2 less than 5 times it's base;
Height = 5x - 2
the area of the triangle is 12 square feet;
Area A = 12 ft^2
The area of a triangle is;
Area A = 1/2 × base × height
Substituting the base and height;;
Area A = 1/2 × x × (5x-2)
Area A = 1/2 × (5x^2 - 2x)
Area A = 12
12 = 1/2 × (5x^2 - 2x)
Multiply through by 2.
24 = (5x^2 - 2x)
5x^2 - 2x -24 = 0
Solving the simultaneous equation;
x = 2.4 or -2
Since the base cannot be negative;
x = 2.4 ft
Height h = 5x -2 = 5(2.4) - 2 = 12 - 2 = 10 ft
Base x = 2.4
Height h = 10 ft
The function h(x) shown is the result of combining two functions, f(x) and g(x), by addition. Which statement could be true of the two functions? The domains of both f(x) and g(x) must be (–[infinity], [infinity]). The domains of both f(x) and g(x) must be (0,[infinity]). The domain of f(x) is (–[infinity], 0), while the domain of g(x) is (0, [infinity]). The domain of f(x) is (–[infinity], 0], while the domain of g(x) is [0, [infinity]).

Solve for v.
4v = 676
Answer:
v=169
Step-by-step explanation:
[tex]4v=676[/tex]
Divide by 4.
[tex]v=\frac{676}{4}[/tex]
[tex]v=169[/tex]
Hello!
Answer:v = 169
Explanation:Since it is being multiplied (4v), we're going to have to use the opposite operation to solve. The opposite of multiplication is division.
Divide both sides of the equation by 4:
[tex]\frac{4v}{4}[/tex] = [tex]\frac{676}{4}[/tex]
v = 169

what is 10 + x = 24?
Answer:
x=14
Step-by-step explanation:
subtract 10 on both sides
24-10=14
x=14
Answer:
x = 14
Step-by-step explanation:
10 + x = 24
-10
x=14
( You subtract 10 from both sides. 24-10 =14. Therefore x =14

Pierce is making a rectangular frame for a photo collage that has a perimeter of 72.2 72.2 inches. The length of the frame is 20.3 20.3 inches. Write an equation to find the width of the frame, x
Answer:
[tex] P = 2x+2y[/tex] (1)
And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:
[tex] P-2y = 2x[/tex]
[tex] \frac{P-2y}{2} =x[/tex]
And replacing we got:
[tex] x = \frac{72.2 in -2*20.3 in}{2}= 15.8 in[/tex]
And the width for this case would be 15.8 in
Step-by-step explanation:
For this case we know that the photo is rectangular. Let's define:
x = the width, y= the length
And we know that the perimeter is given by:
[tex] P = 2x+2y[/tex] (1)
And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:
[tex] P-2y = 2x[/tex]
[tex] \frac{P-2y}{2} =x[/tex]
And replacing we got:
[tex] x = \frac{72.2 in -2*20.3 in}{2}= 15.8 in [/tex]
And the width for this case would be 15.8 in

Answer:
12
Step-by-step explanation:
Each song should be 12 minute long.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
The band will play for 60 minutes.
If they want to play 5 songs in a duration of 60 minutes, we have to divide the total amount of minutes by how many songs they have to play.
Using the formula,
Total Duration / Total Songs = Duration Per Song
60 / 5 = 12
Therefore, Each song should be 12 minute long.

determine whether the function represented by the equation is quadratic
Answer:
not quadratic because there is not a quadrat in it.
Step-by-step explanation:
The graph of a quadratic funtion is a parabola.
The general form of quadratic function is this:
f(x) = ax² + bx + c
Where a, b, and c are numbers.
Please uderstand that a can not be zero, which means that any quadratic function has at least one term with ² in it.
In this example, there is no quadrat visible, so it is not quadratic. By the way, y = -9x + 19 is a so called linear equation. It's graph is a line.
