Considering the definition of an equation and the way to solve it, the number of monthly movies watched that would make the two plans have an equal monthly cost is 26.
Definition of equationAn equation is an algebraic equality in which there are unknowns with unknown value. The unknown represents the number, if any, that makes the equality true. This unknown number is the solution of the equation.
This is, the solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.Number of monthly movies watchedBeing "x" the number of monthly movies watched, you know that:
Plan A costs $34 per month plus $2 per movie watched. → A= 34 + 2xPlan B costs $8 per month plus $3 per movie watched. → B= 8 + 3xIf the two plans have an equal monthly cost, the equation in this case is:
A= B
34 + 2x= 8 + 3x
Solving:
34 - 8= 3x - 2x
26= x
Finally, 26 monthly movies watched would make the two plans have an equal monthly cost.

PLEASE HELP!! It's easy i'm just Dum. Solve for x, look down below for more info.
By using the fact that the two angles are vertical angles, we will write and solve a linear equation to fine that the value of x is 20.
How to find the value of x?Here we assume that both of the horizontal lines are parallel. Then the two marked angles (the ones that depend of x) are vertical angles.
This means that the measure of these angles is the same one, then we can write:
(5x - 8)° = (3x + 32)°
So we can solve that linear equation to find the value of x, we will get:
5x - 8 = 3x + 32
Grouping like terms we get:
5x - 3x = 32+ 8
2x = 40
x = 40/2
x = 20
The value of x is 20.

As per the tangent angle, the value of x in the given diagram is 7cm.
Tangent angle
The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
Given:
Here we have the two right angled triangle, through this we have to identify the value of x.
According to the given question, we have a diagram with two right angled triangles.
Now, in the upper right angled triangle
tan 50° = opposite side / 5
⇒ 1.19 = 0pposite side/ 5
⇒ opposite side = 1.19 × 5
⇒ opposite side = 1.2 × 5
⇒ opposite side = 6cm
Now, the opposite side with respect to the angle 50 degrees in the upper right angle triangle is a adjacent side according to angle 38 degrees in the lower right angle triangle.
So, in the lower right angle triangle.
tan 38° = x / adjacent side
⇒ 0.78 = x/6
⇒ x = 0.78 × 6
⇒ x = 4.68
⇒ x = 7cm
Hence, the value of x in the given diagram is 7cm.

84. the centers for disease control and prevention reported in 2012 that 1 in 88 american children had been diagnosed with an autism spectrum disorder (asd). a. if a random sample of 200 american children is selected, what are the expected value and standard deviation of the number who have been diagnosed with asd?
a) The expected value is calculated to be 2.273 and b) the standard deviation is 1.499 if a random sample of 200 children is selected.
According to the report 1 in 88 American children has been diagnosed with ASD, therefore the probability can be given as;
p = 1 / 88
a) the expected value can be calculated as follows;
E (X) = n × p
here n = sample size = 200
p = probability = 1 / 88
E (X) = 200 × 1 / 88
E (X) = 2.273
b) To find the standard deviation, first, we have to determine the variance of the random variable;
V (X) = n × q × p
V (X) = 200 × 87/88 × 1/88
V (X) = 2.2468 = 2.247
Now we can calculate the standard deviation as follows;
standard deviation = √V(X)
standard deviation = √2.247
standard deviation = 1.499
Therefore, the expected value and standard deviation are calculated to be 2.273 and 1.499 respectively.

What are mathematical operations?An operation in mathematics is a function that converts 0–n parameters or operands into a definite output value. The complexity of the operation depends on how many operands there are.
The operations that are most frequently studied are binary operations (i.e., operations of arity 2), which include addition and multiplication, and unary operations (i.e., operations of arity 1), which include additive inverse and multiplicative inverse. A zero-arity operation, also known as the nullary operation, is a constant. An illustration of a ternary operation, also known as an operation of arity 3, is the mixed product.
Usually, it is considered that the arity is constrained. Even so, infinitary operations are occasionally considered, in which case the "normal" finite dimensionality operations are referred to as finiteary operations.
A partial operation is described as being similar to an operation but using a partial function in place of a function.

a clothing business finds there is a linear relationship between the number of shirts, n, it can sell and the price, p, it can charge per shirt. In particular, historical data shows that 6000 shirts can be sold at a price of $81, while 10,000 shirts can be sold at a price of $45. Give a linear equation in the form p = mn + b that gives the price p they can change charge for n shirts.
Answer: p = ____
The linear equation in the form p = mn + b that gives the price p they can change charge for n- shirts is; p = (9/1000)n - 9.
What is defined as the linear equation?A linear equation is really an algebraic equation with only a constant and the first-order (linear) term of the form y=mx+b, in which m is the slope and b is indeed the y-intercept.The above is sometimes regarded to as a "linear equation of two variables," in which y and x are the variables.As per the given question;
number of shirts = n
The charge per shirt = p.
The equation describing the relation is;
p = mn + b
The price of 6000 shirts = $81.
Put the value is equation;
81 = 6,000m + b .....eq 1
The price of 10,000 shirts = $45.
45 = 10,000m + b .....eq 2
Solving eq 1 and eq 2 by elimination method.
m = 9/1000
Put the value of m in eq 2 and find b.
b = -9
Now, put the value of b and m in the equation.
p = (9/1000)n - 9
Thus, the equation in the form p = mn + b that gives the price p they can change charge for n shirts is; p = (9/1000)n - 9.

What is a force?A force is effect that can alter an object's motion according to physics. A force can cause an object with mass to accelerate when it changes its velocity, for as when it moves away from the rest. An obvious way to describe force is as push or a pull. A force is vector quantity since it has both magnitude and direction. It is calculated by using newton SI unit (N). Force is denoted by letter F. (formerly P).
The net force acting on object is equal to the rate at which its momentum varies over time, according to Newton's second law in its original formulation. This law suggests that object's acceleration is directly proportional to the net force acting on it, is in the direction of the net force, and is inversely proportional to mass of the object if the object's mass is constant.

Probability is a branch of mathematics in which we determine how likely an event is to happen. It is used when we are not sure about the result or outcome of an event so we consider the probabilities of certain outcomes.
In this case, there are 12 zodiac signs, out of which one is yours. So the probability or chance that the 4 randomly picked people do not share your zodiac sign can be determined as follows;
Probability of one person not having your zodiac sign: 11/12
Probability of 4 people not having your zodiac sign;
11/12 × 11/12 × 11/12 × 11/12 = 0.706
