The probability of rolling a number less than 14 among {1,2,3,4} is 1.
Given The dice is 4 sided. Likely outcomes is {1,2,3,4} and we have to find the probability of rolling a number less than 4.
Probability is the likeliness of happening an event among all the events possible. The value of probability cannot be negative or greater than 1. It lies between 0 to 1. The formula of calculating probability is:
Probability= number of events/ total number of events.
Total likely outcomes=4 {1,2,3,4}
Numbers less than 14 = 4
Probability of rolling a number less than 14=1/4
=0.25 because all number less than 14 is present.
1,2,3,4 are all less than 14.
and because all numbers are included that's why the value of probability is 1.
Hence the probability of rolling a number less than 14 is 1.

What is unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
One litre is equal to 1000 millilitres. Tony made 14 Liter of lemonade, therefore, Tony made 14,000 millilitres of lemonade. His guest drank 9500 millilitres. Therefore, the lemonade left with Tony is,

Which best describes the relationship between the line that passes through the points (9, –5) and (5, –2) and the line that passes through the points (–4, –2) and (–8, 1)?
Since the lines have the same slopes, hence they are parallel lines
How to determine the relationship between linesWe can determine the relations by knowing the slopes of the line
For the line with coordinates (9, –5) and (5, –2)
Slope = -2+5/5-9
Slope = -3/4
For the line with coordinates (–4, –2) and (–8, 1)
Slope = 1+2/-8+4

After five science tests, Sonya's average score
is 89. If she gets a 95 on the sixth test, what is
her new average?
A. 89.50
B. 89.90
C. 90.00
D. 90.50
Answer:
C
Step-by-step explanation:
The sum of Sonya's 5 initial tests = 89*5 = 445.
445 + 95 = 540 (sum of the 6 tests)
Average = 540/6 = 90
Hence C
Answer:
C. 90.00
Step-by-step explanation:
We find average by adding up all values in a data set and dividing by the total number of values we have
We can say that Sonya got 89 for each test (it doesn't matter what each test score exactly was--you'll see why in a second)
So, we can add up 89 five times (5 tests have occured)
*I say add up, because that's what average is, but you can find this number by multiplying 89 · 5
89 · 5 = 445
(89 + 89 + 89 + 89 + 89 = 445)
Now, we need to add up our new value: 95
445 + 95 = 540
So, we can now divide 540 (sum of all values) by 6 (total number of values)
540 ÷ 6 = 90
So, C (90.00) is her new average

Which of the following are solutions to the equation below?
Check all that apply.
x²-2x-24 = 0
Answer:
[tex]x=6, x=-4[/tex]
Step-by-step explanation:
1) Let's solve this quadratic equation by factorizing. We need to find two numbers that multiply to -24 and add up to -2 simultaneously. If we pull out the factors of -24, two of them will be -6 and 4, which multiply to -24 as well as add up to -2.
3) Write [tex]-2x[/tex] as a sum.
[tex]x^2-6x+4x-24=0[/tex]
Now, we can factor them out by grouping.
[tex]x^2-6x+4x-24=0\\x(x-6) + 4(x-6)=0[/tex]
Since, [tex]x -6[/tex] is common in both of the factors, we only take one of the [tex]x -6[/tex] along with [tex]x[/tex] and [tex]4[/tex] and all equated to 0.
[tex](x-6)(x+4) = 0[/tex]
Solve for x: [tex]x-6=0[/tex]
[tex]x=0+6\\x=6[/tex]
Solve for x: [tex]x+4=0[/tex]
[tex]x=0-4\\x=-4[/tex]
Therefore, our solutions to this quadratic equation are [tex]x=6, x=-4[/tex].

Answer:
A system of two linear equations can have one solution, an infinite number of solutions, or no solution.
===================================================
Explanation:
An equation is something like [tex]\text{y} = 2\text{x}+5[/tex] and [tex]\text{y} = 3\text{x}+7[/tex]
When we combine two such equations to form a group (of sorts), we consider this to be a system of equations.
We use a single curly brace to write the system
[tex]\begin{cases}\text{y} = 2\text{x}+5\\\text{y} = 3\text{x}+7\end{cases}[/tex]
Here are the three cases mentioned when it comes to solutions.
If the two lines intersect at exactly one point, then the system has exactly one solution. This system is consistent and independent.If the two lines are the same, they intersect at infinitely many points along that line. One line perfectly overlaps the other. Therefore, this scenario leads to infinitely many solutions. The system is dependent because one line depends on the other (since they are one in the same). This system is also consistent because it has at least one solution. Lastly, if the two lines are parallel, then they never cross. The lack of crossing points means there aren't any solutions. We call this an inconsistent system.Side note: Any solution is of the form (x,y)
