Answer: 7 over 30 times t plus negative 21
Step-by-step explanation:
(2/5t - 7 + 2/3t) - (5/6t + 14)
(16/15t - 7) - (5/6t + 14)
16/15t - 7 - 5/6t - 14
7/30t - 7 - 14
7/30t - 21, which is the same as 7/30t + -21

X cannot be a binomial variable because it matches a geometric distribution having parameters of p = 0.02 and is instead a geometric variable.
What is a Binomial Distribution?
The number of successes and failures in a series of n (a finite value) independent trials or experiments is represented by a binomial distribution.
Given that the producer of electronics is aware that 2% of computer processors are faulty, and
The random variable X represents the number of processors it takes to find a bad processor.
X does not constitute a binomial variable in this situation.
In the example above, the amount of failures (processors) is being counted up until the initial success (a malfunctioning processor) is attained.

The expression of the possible values of the number is x < 16
How to determine the possible values of the number?The statement is given as
Eight less than four times a number is less than 56.
Rewrite the statement as an expression
So, we have
4 * number - 8 is less than 56
Represent the number with x
So, we have
4 * x - 8 is less than 56
This gives
4 * x - 8 < 56
Add 8 to all sides
4 * x < 64
Divide both sides by 4
So, we have
x < 16

if maggie corrected her mistake, what would be the correct answer for x?
The correct value of x will be 9 as it is alternate angles which are equal so 4x+2=7x-25 for the given set of intersecting lines.
What is angle?An angle is a figure in Euclidean geometry made up of two rays that share a common endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
What is alternate angles?When a transversal intersects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines. At two different locations, the transversal passes through the two lines that are coplanar.
Here,
4x+2=7x-25
3x=27
x=9
The value of x would be 9 and the value of angle is 38°.
Given that the alternate angles are equal, 4x+2=7x-25 for the given set of intersecting lines, the proper value of x will be 9.

The rule of the rotation to the right is a rotation by 90° clockwise about the origin.
We need to describe the rule of the rotation to the right.
A figure and its rotation keep the same shape and size but face in a new direction. A figure can be rotated in either a clockwise or counterclockwise direction. The angle of rotation is the measure of how far a figure is rotated about its centre of rotation. The angle of rotation is often expressed in degrees. We specify the rotation's degree measure and direction.
If the rotation is applied to the right, it means a rotation of 90° in a clockwise direction about the origin.

Graph the line with slope -3/4 and y-intercept 9.
The equation of the line with slope -3/4 and y intercept 9 is y=-3/4x+9.
Based on the conditions formulate:
m=-3/4
and b = 9
Write the equation of the linear function:
y=mx+b
substitute m=-3/4 and b=9 into y=mx+b:
y = -3/4x+9
A line's equation must be in the Slope-Intercept Form, y = mx + b, in order to be graphed using its slope and y-intercept.
This format makes it simple to read off the slope and y-intercept values. The y-intercept is the constant term b, whereas the slope is just the m coefficient of the variable x.
plot the y intercept (0,9) in the xy axis.
Use the slope to locate a different point beginning at the y-intercept. The direction you travel from one point to another is contained in the slope.

Indian cricket team won 4 more matches than it lost with NewZealand. If it won 3/5 of its matches
,how many matches did India play?
As per the unitary method, the number of matches did India play is 20.
Unitary method:
Unitary method is the method in which we first find the value of a unit quantity and then use it to find the value of any required quantity.
Given,
Indian cricket team won 4 more matches than it lost with New Zealand.
Consider If it won 3/5 of its matches, then we need to find the number of matches did it played.
Let us consider the number of matches lost = x
Number of matches won = x + 4
Therefore, the total matches played
=> x + x +4
=> 2x + 4
So, we know that, it won 3/5 th of the matches,
Then it can be written as,
=> x + 4 = 3/5 (2x +4)
Cross multiply it,
=> 5(x + 4) = 3(2x + 4)
=> 5x + 20 = 6x + 12
=> x - 8 =0
=> x = 8
Then the total number of matches played by India is,
=> 2(8) + 4
=> 16 + 4
=> 20.
Therefore, 20 matches are played by India.

The function at x = -2 has a value of -1
How to evaluate the function?The graph represents the given parameter
From the question, we understand that:
The graph is a piecewise function
This means that there are breaks in the values represented on the graph
The x value is given as
x = -2
When this value is traced on the graph, we have
When x = -2, y = -1
When x = -2, y = 7
By considering the endpoint values of the domain, we have
When x = -2, y = -1 (inclusive)
When x = -2, y = 7 (not inclusive)

What are the types of solutions to a system of equations?The types of solutions of a system of equations are; no solution, infinitely many solutions, one solution
The given expression is; 2•x + 9 + 3•x + x
The above expression when given as the right hand side of an equation gives;
2•x + 9 + 3•x + x = _x + _No solution;
A situation where the right and left hand side of an equation has no solution is where they form lines that do not meet or intersect.
Two lines do not meet when they are parallel, that is when their slopes are the same and however, their y–intercepts are different
Which gives;
Simplifying the expression on the right into the form, m•x + c, where m represents the slope, gives;
2•x + 9 + 3•x + x = 6•x + 9
An expression that can be written on the left that is parallel but does not intersect with the graph of the expression on the left is therefore; 6•x + 5
The first equation is therefore;
No solution;

When the equation has one solution it means that the straight line graphs of the left and right sides intersect once.
Therefore, the lines are not parallel and therefore, the slopes are different, which gives the expression on the right as follows;
2•x + 9 + 3•x + x = 5•x + 9Infinitely many solutions;
When two equations have infinitely many solutions, we have that the equations meet at infinitely many points, such that the equations are essentially the same, which gives the correct option as follows;

The perimeter of the triangle below is 89 units. Find the length of side BC.
Write your answer without variables.
Answer:
BC = 10 units
Step-by-step explanation:
Perimeter of triangle:Perimeter = Sum of all sides
y + 1 + 4y + 5y - 2 = 89 units
y + 4y + 5y + 1 - 2 = 89
Combine like terms,
10y - 1 = 89
Add 1 to both sides,
10y = 89 + 1
10y = 90
Divide both sides by 10,
y = 90 ÷ 10
y = 9 units
BC = y + 1

What is equation of line in slope intercept form?The slope intercept form of such a straight line is among the most common ways to represent a line's equation. When given the slope of a straight line and the y-intercept, the slope intercept equation can be used to find the equation of a line ( the y-coordinate of the point in which a line intersects the y-axis).For a straight line with a slope,'m,' and 'b' as the y-intercept, the slope intercept form equation is: y = mx + b.For the given question;
The equation of the parallel line is given as;
9x - 4y = 7
Find the slope of the equation by comparing the equation with the standard form.
4y = 9x - 7
y = 9x/4 -7/4
Slope = m = 9/4
As, the line is parallel to the line passing from the point (5, -2).
Thus, the slope of both lines will be equal.
The equation in slope intercept form is found using,
y - y1 = m(x - x1)
y + 2 = (9/4)(x - 5)
Solving,
y = 9x/4 - 37/4
Where, slope is 9/4 and y-intercept is -37/4.

One side = 2cm
Let the one side given be Base
Then, base = 2cm
Now, by Pythagoras Theorem we can find out the missing length or Perpendicular of the triangle
By Pythagoras Theorem:
H² = P² + B²
If we have to find perpendicular then,
P² = H² - B²
or,
P = √H² - B²
