Step-by-step explanation:
Probability is the likeliness of happening of an event.
Probability of any event A can be be defined by
no. of time event A happens/ total no. all possible event that can occur
___________________________________
In the problem
probability of occurrence of 1 on rolling a cube is needed.
A cube has six sides with one written on one sides and rest has 2,3,4,5,6.
No of times 1 can occur on rolling the dice once will be = 1
Since there six sides and and each has different number (1,2,3,4,5,6)
There is chance that each of the number can come.
Thus, total no possible outcome = 6
Probability of occurrence of 1 = No of times 1 occurs on rolling the dice /total no possible outcome = 1/6
_____________________________________________
If dice is rolled 1 time there is 1/6 chance that 1 will be the outcome.
If dice is rolled 1*60 time then there is 1/6*60= 10 chance that 1 will be the outcome
Thus , If you were to roll a six-sided number cube 60 times, about 10 times it is expected that the number cube to land on a 1.

The table below represents the equation: y = 1.5x – 2 A 2-column table with 4 rows. Column 1 is labeled x with entries negative 3, 0, 3, 6. Column 2 is labeled y with entries negative 6.5, negative 2, blank, blank. Y = 1.5 (negative 3) minus 2. y = 1.5 (0) minus 2. If you completed this table, would each input have exactly one output?
Answer:
yes, each input would have exactly one output if you completed this table.
Step-by-step explanation:
Yes, there is only one output for each input. The table's linear equation provides exactly one value of y for each value of x.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
What is the linear equation?The general equation of a line is y = mx + c
where m is the slope of the line and c is the intercept.
A linear equation is defined as an equation in which the highest power of the variable is always one.

Answer:
(2(an))-2
Step-by-step explanation:
How do you find the median of a data set when you have an even number of values?
Answer:
If there is an even number of numbers, the median is the average of the two numbers in the middle.
Step-by-step explanation:
To find the median of any set of numbers, put them in order from smallest to greatest. If a number occurs more than once, list it more than once. The number in the middle is the median. If there is an even number of numbers, the median is the average of the two numbers in the middle. For your first example, we line them up: 3, 6, 6.
Answer:
Set them from least to greatest and remove one from each side until you find the middle number! If you're left with 2, add them both and divide by 2.

Sherri hikes on the Pacific Coast trail. She plans to hike 3.72 miles. If she hikes at an average speed of 1.2 miles per hour, how long will she hike?
Answer:
3.1 hours
Step-by-step explanation:
Average Speed=Distance Traveled ÷ Time Taken
Sherri plans to hike 3.72 miles at an average speed of 1.2 miles per hour.
Average Speed=1.2 miles per hour.Distance =3.72 milesTherefore:
1.2 miles per hour=3.72 miles ÷ Time
1.2 miles per hour X Time=3.72 miles
Time = 3.72 ÷ 1.2 hours
Time taken by Sherri=3.1 hours
Sherri will hike for 3.1 hours.

A cylindrical tank is half-full of oil. The cylinder has base radius of 100cm.The height of the cylinder is 250cm. 1 litre =1000cm cubed
How many litres of oil are in the tank? Round your answer to the nearest litre.
Answer:
Step-by-step explanation:
area of a cylinder=. V=πx r^2xh
so...
πx100^2x125=3926990.817 (the height is 125 because only half of it has oil)
3926990.817/1000=3927litres
Batman, who is having a slow year for crime, has resorted to saving cats from very tall buildings. Our fearless 6 foot tall hero is 40 feet from the the Petsmart building the cat was trying to break in to, in order to get his paws on the pumpkin spice cat nip. Batman sights the top of the building at a 30° angle, how high is the building?
Answer:
29.094 feet tall
Step-by-step explanation:
tan(30) = [tex]\frac{x}{40}[/tex]
so tan is opposite over adjacent which means that we should be able to solve for the opposite as we have the angle (30) and the distance from Batman to to building, which is (40 feet), with these numbers you will do, tan(30) = [tex]\frac{x}{40}[/tex] and from that you will solve for x, and from x you add the 6 foot of batmans height
Which dimensions can create more than one triangle?
three angles measuring 259, 65°, and 90°
three angles measuring 509, 50°, and 50°
three sides measuring 5 in., 12 in., and 13 in.
three sides measuring 4 ft, 8 ft, and 10 ft
Answer:
three sides measuring 4 ft, 8 ft, and 10 ft
Step-by-step explanation:
To choose which dimensions that can create more than one triangle, we consider the given values carefully and how possible it will be to construct.
The only dimensions given in the option that will be possible to create more than one triangle from it, is three sides measuring 4 ft, 8 ft, and 10 ft.
4 ft, 8 ft, and 10 ft are in simple multiple of 2
4 ft, 8 ft, and 10 ft = 2 (2 ft, 4 ft, and 5 ft ), with this we can construct two triangles with three sides measuring 2 ft, 4 ft, and 5 ft.

Find the value of x.
Answer:
x = 61
Step-by-step explanation:
x and 29 are complementary angles so they add to 90 degrees
x+29 = 90
Subtract 29 from each side
x+29-29 = 90-29
x = 61
Answer:
61 degrees = x
Step-by-step explanation:
Since angle measures x and 29 are complementary angles, subtract 29 from 90 degrees.
90 - 29 = 61 degrees is the value of x
Which statement is true? Question 10 options: A) |13| = – 13 B) – |13| = 13 C) |–13| = 13 D) – |–13| = 13
Answer:
The answer is C
Step-by-step explanation:
Every negative or positive number in the modulus while be positive at the end
The true statement is C) |–13| = 13, indicating that the absolute value of -13 is 13, representing the distance of -13 from zero on the number line.
How to Solve Absolute Value Equations?The true statement is: C) |–13| = 13, as explained below.
The expression |–13| represents the absolute value of -13, which is the distance of -13 from zero on the number line, always resulting in a non-negative value.
|–13| = 13, because the absolute value of -13 is 13, meaning it is 13 units away from zero on the number line. So, the correct option is C) |–13| = 13.

How to solve #2 if you don’t know any of the side lengths?? (We’re learning about Pythagorean Theorem)
Answer:
Applying Pythagorean theorem in right triangle with c is longest side and a, b are the other sides:

=> a^2 = c^2 - b^2
=> b^2 = c^2 - a^2

Rearrange the equation so q is the independent variable.
9q-4=3r-6
r = __
Answer:r=3q+2/3
Step-by-step explanation:
Step 1: Flip the equation.
3r-6=9q-4
Step 2: Add 6 to both sides.
3r-6+6=9q-4+6
3r=9q+2
Step 3: Divide both sides by 3.
3r/3=9q+2/3
r=3q+2/3
Hopefully it’s right
Rearranging the equation, so q is the independent variable as r=(9q+2)/3.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 9q-4=3r-6.
Now, 9q-4+6=3r
3r=9q+2
r=(9q+2)/3
Therefore, rearranging the equation, so q is the independent variable as r=(9q+2)/3.

PLEASE HELP me with the magic square
Fill in each slot in the square with variables a, b, c, d, and e, in order from left-to-right, top-to-bottom. In a magic square, the sums across rows, columns, and diagonals all add up to the same number called the magic sum.
The magic sum is -3.9, since "diagonal 2" (bottom left to top right) has all the information we need:
3 + (-1.3) + (-5.6) = -3.9
Use this to find the remaining elements
row 1:a + b + (-5.6) = -3.9
row 2:c + (-1.3) + d = -3.9
row 3:3 + e + 0.02 = -3.9
column 1:a + c + 3 = -3.9
column 2:b + (-1.3) + e = -3.9
column 3:(-5.6) + d + 0.02 = -3.9
diagonal 1 (top left to bottom right):a + (-1.3) + 0.02 = -3.9
You will find
a = -2.62
b = 4.32
c = -4.28
d = 1.68
e = -6.92
