The probability of picking a purple and green marbles is 0.05.
What is a probability?Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.
Number of purple marble = 50
Number of green marbles = 10
Total number of marbles = 100
The probability of picking a purple and green marbles will be:
= 50/100 × 10/99
= 0.05

The square root of 4x^10 is (4x^10)^1/2.
Therefore, the square root of 4x^10 is (2x^5)^1/2.
This means that the square root of 4x^10 is 2x^(5/2).

The lines passing through points A (- 3, 10) and (1, 2) , B (- 1, 6) and (0, 2) , and C (1, 2) and (3, 4) has positive y-intercept.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
As we know, the slope formula is:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
A (- 3, 10) and (1, 2)
m = (2-10)/(1+3)
m = -8/4 = -2
y = mx + c
y = -2x + c
Plug (- 3, 10)
10 = -2(-3) + c
c = 10 - 6 = 4 (positive y-intercept)
Similarly, for the other points:
B (- 1, 6) and (0, 2)
y = -4x + 2 (positive y-intercept)
C (1, 2) and (3, 4)
y = x + 1 (positive y-intercept)
D (0, - 4) and (3, - 2)
y = 0.667x - 4 (negative y-intercept)
E (3, 1) and (5, 2)
y = 0.5x -0.5 (negative y-intercept)
Thus, the lines passing through points A (- 3, 10) and (1, 2) , B (- 1, 6) and (0, 2) , and C (1, 2) and (3, 4) has positive y-intercept.

After washing dishes, water drips from the faucet. The graph shows the number of cups of water that drip from the faucet over time. How many gallons of water drip from the faucet in 24 hours?
The number of gallons of water that drip from the faucet in 24 hours is; 6 gallons
How to Interpret Linear Graphs?We can see from the graph, that the x-axis represents the time in hours that the cup of water has dripped from the faucet while the y-axis represents the number of cups that has dripped from the faucet over a specific time frame.
Now, from the graph, we see the following coordinates;
(1, 4)
(2, 8)
(3, 12)
(4, 16)
Thus;
Slope = (8 - 4)/(2 - 1)
Slope = 4
Thus, the rate is 4 cups drip per hour.
1 hour = 4 cups dripping
Thus; 24 hours = (24 * 4)/1 = 96 cups
Now, conversion rate of cups to gallon is;
1 cup = 1/16 gallon
Thus;
96 cups = 96 * 1/16 = 6 gallons

Marc earns $3,300 per month in gross income. He withholds 28%
of his paycheck in taxes and deductions. What is his monthly net
pay?
Answer:
$2376
Step-by-step explanation:
Money Marc withholds from his gross income in taxes and deductions: We can do this by multiplying his gross income by the withholding rate of 28%, which gives us 0.28 * $3,300 = $<<0.28*3300=924>>924.
Next, we need to subtract this amount from Marc's gross income to find his net pay. This gives us $3,300 - $924 = $<<3300-924=2376>>2376. Therefore, Marc's monthly net pay is $2376.

Y=-3x-17 and y=x-1
Solving linear systems by substitution
Answer:
x = 8, y = 7
Step-by-step explanation:
The two equations are
y = 3x - 17 [1]
y = x -1 [2]
Substitute y = x - 1 in the first equation
x - 1 = 3x - 17
==> x - 3x = -17 + 1
==> -2x = -16
==> x = -16/-2 = 8
Sub for x in [2]
y = 8 - 1 = 7

Suppose that for each foot of land along a street, the

plot of land.
800
46 ft
28 At
A
Street
Approximately, how much is the annual tax for the plot?
The annual tax for the plot based on the triangle and the side lengths is $1488
How to determine how much is the annual tax for the plot?From the question, we have the following parameters that can be used in our computation:
Annual tax per foot = $12
Shape of the land = Triangle
Parameters of the triangle are represented as
Angle between sides = 80 degrees
Sides = 46 ft and 28 ft
The side represented as "Street" is calculated as
Street = The square root of Sum of the squares of the other sides - 2 * the product of the other sides * the cosine of the angle between them
Mathematically, this is represented as
Street = √46² + 28² - 2 * 46 * 28 * cos(80)
Evaluate
Street = 50
So, the perimeter of the land is
Perimeter = 50 + 46 + 28
Perimeter = 124 foot
Recall that:
Annual tax per foot = $12
So, we have
Yearly annual tax per foot = $12 * 124
Evaluate
Yearly annual tax per foot = $1488
Hence, the yearly annual tax per foot = $1488

Find the missing angle:

The missing angle RPQ between the intersected chord is 115 degrees.
How to find the angle between intersected chord?The intersecting chords theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle
If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.
Therefore,
∠RPQ = 1 / 2 (arc angle RQ + arc angle SA)
arc angle RQ = 175 degrees
arc angle SA = 55 degrees
Hence,
∠RPQ = 1 / 2 (175 + 55)
∠RPQ = 1 / 2 (230)

Find the domain of where f(x) = x + 10 and g(x)=x².
The domain of the function f(x)=x+10 is (-∞, ∞) and for the function g(x)=x² is (-∞, ∞).
What is meant by domain?If a formula specifies a real function f, it may not be defined for some values of the variable. The natural domain or domain of definition of f is the set of real numbers on which the formula can be evaluated to a real number in this case. A partial function is often referred to just as a function, and its natural domain is referred to simply as its domain.
Given, f(x) = x + 10
