The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To simulate an event that has a probability of success of 20%, we need to randomly generate numbers from 0 to 9 such that there is a 20% chance of getting a "success" number.
Since there are 10 possible numbers to choose from, 20% of them would be 2 "success" numbers.
So, any group of numbers that contains two "success" numbers out of 10 would represent a success.
For example,
The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.
Other groups with two "success" numbers would also be valid.
Thus,
The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.

Find the next number in the pattern: 12, 24, 48, 96, ...
Answer:
196
Step-by-step explanation:
12, 24, 48, 96, __?
The next term will come by multiplying with number 2
12 *2 = 24,
24*2 = 48,
48*2 = 96,
96*2 = 192,
& The answer will be 196
Answer:
Each time the pervious number is being doubled (multiplied by 2). So the next number would be 96 x 2. So, the next number on the pattern is 192.

This is the graph of y = x2 -7x + 3. Work out x2 -7x + 3 = 0 (careful with the scale).
Answer:
x=6.54138
x=0.458619
Step-by-step explanation:
using the Quadratic Formula where
a = 1, b = -7, and c = 3
x=−b±[tex]\sqrt{b^{2} -4ac}[/tex]/2a
x=−(−7)±√[(−7)2−4(1)(3)]/2(2)
x=7±√(49−12)/2
x=7±√37/2
The discriminant b2−4ac>0
so, there are two real roots.
Cannot Simplify the Radical:
x=[tex]\frac{7+-\\\sqrt{37} }{2}[/tex]
which becomes
x=6.54138
x=0.458619

Write an equation for each translation of y = |x|.
15.5 units left
A. y = | x | – 15.5
B. y = | x + 15.5 |
C. y = | x – 15.5 |
D. y = | x | + 15.5
Answer:
B. y = | x + 15.5 |
Step-by-step explanation:
The + inside the absolute value equation really means -.
So there is a horizontal shift of 15.5 units left.
Answer:
B. y = | x + 15.5 |
Step-by-step explanation:
Given : y= |x|.
To find : Write an equation for each translation of y= |x|. 15.5 units left .
Solution : We have given that y= |x|.
By the translation rule :if function transformed to f(x ) →→→ f(x +h) Then graph of the function would shift h units left.
For translation 15.5 unit left we need to add 15.5 in function y= |x|.
y = | x + 15.5 |
Therefore, y = | x + 15.5 |.
How would you describe the graph for the equation ? lxl = 1
Answer:
Step-by-step explanation:
Note that |-x| = 1, just as |x| = 1. Removing the absolute value operator in both cases, we get x = 1. In two dimensions the graph would be a solid dot at = 1.

Two sides of a triangle are 11 can and 14 cm what are all the possible values for the length of the third side
Answer:
Step-by-step explanation:
The third side is thus, less than 14 + 11 = 25 cm. The side cannot be less than the difference of the two sides. Thus, the third side has to be more than 14 - 11 = 3 cm. So, the length of the third side could be any length greater than 3 cm and less than 25 cm.
On a bicycle, Jack can travel 20 miles in 4 hours. How many miles did he travel in one hours?
Answer:
Jack traveled 5 miles in 1 hour
Step-by-step explanation:
Answer: In one hour Jack can Travel 5 miles.
Step-by-step explanation:
Jack can travel 20 miles in 4 hours. So to find out how many miles Jack can travel in 1 hour, we need to divide the number of miles for 4 hours (which is 20) by 4.
20 miles ÷ 4 hours = 5 miles in 1 hour
Therefore, we can say Jack can travel 5 miles in 1 hour.

Malik's average pace was 5.5 minutes per mile.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given; Malik uses an app on his phone to track how far he rides his bike. Yesterday, he biked a new trail in a total of 57.5 minutes, including a 2.5-minute water break. The app notified Malik that he rode 10 miles.
Now, This equation represents the situation.
Now, solve the equation for p;
10p+2.5 = 57.5
Subtract 2.5 from both sides;
10p = 55
Divide both sides by 10
p = 5.5
Therefore, Malik's average pace was 5.5 minutes per mile.

Martin is sewing costumes for the school play. He needs 1/3
yard of ribbon for each costume. He has 12 3/4 yards of
ribbon left. How many costumes can he finish making?
Answer:
simple convert to improper to subtract
51/4 turn to a common denominator
so multiply by 3
153/12. 4/12
then just divide 153 by 12 = 12.75* 3 bc 3 costumes are one yard and you get 38.25 costumes or 38 bc you cant have .25 of a costume
The no. of costumes Martin can make is 38.
It is given that 1/3 yards of Ribbon is needed for each costume and [tex]12\frac{3}{4}[/tex] yards of Ribbon is left.
We have to find out the no. of costumes which Martin can make.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations and the symbols are called variables.
As per the question ;
Ribbon needed for each costume = 1/3 yards
Ribbon left = [tex]12\frac{3}{4}[/tex] yards
Let's assume no. of costumes Martin can make is x.
The ribbon needed for x costumes will be ;
= [tex]\frac{1}{3}[/tex] × x
= [tex]\frac{x}{3}[/tex] yards
So ;
The no. of costumes will be ;
[tex]\frac{x}{3}[/tex] yards = [tex]12\frac{3}{4}[/tex] yards
[tex]\frac{x}{3}[/tex] yards = [tex]\frac{51}{4}[/tex] yards
or
4x = 51 × 3
or
x = [tex]\frac{51 * 3}{4}[/tex]
x = [tex]\frac{153}{4}[/tex]
or
x ≈ 38
Thus , the no. of costumes Martin can make is 38.

Find the gradient of the line segment between the points (4,6) and (8,14).
Let a = (x1,y1) = (4,6) and b = (x2,y2) = (8,14)
Then, since the formula of the gradient (or Slope), given two points a and b is :
m = (y2 - y1) / (x2-x1) = (14 - 6) / (8 - 4) = 8 / 4 = 2
Then we know that the gradient is m = 2

Draw a bar diagram and write and solve
an equation.
Yellow shirt $24

The bar diagram is attached below. As we can see, the price of a yellow T-shirt is as three times as the price of a blue T-shirt. Hence, we can construct the following equation to determine the ratio between both prices:
[tex]y = r\cdot x[/tex] (1)
Where:
[tex]x[/tex] - Price of blue T-shirt, in monetary units.[tex]y[/tex] - Price of the yellow T-shirt, in monetary units.[tex]r[/tex] - Price ratio, no unit.If we know that [tex]x = 8[/tex] and [tex]y = 24[/tex], then the price ratio is:
[tex]r = \frac{y}{x}[/tex]
[tex]r = 3[/tex]
The price of the yellow T-shirt is as three times as the price of the blue T-shirt.
