Answer:
heads
Step-by-step explanation:
The difference between the number of heads and tails is 17.
What is Fraction?Every fraction has a numerator and a denominator separated by a horizontal bar known as the fractional bar.
The denominator represents the number of components into which the whole has been subdivided. It is positioned below the fractional bar in the lower section of the fraction.The numerator specifies how many fractional parts are depicted or selected. It is positioned above the fractional bar in the upper section of the fraction.Given:
Jm tosses a biased coin 50 times, and it lands on heads 40 times.
So, the fraction for getting tail out of 50 times
= (50- 40) / 50
= 10 / 50
= 0.2
Now, if the coins tossed 22 more times then number of tails are
= 22 x 0.2
= 4.4
So, the difference between the number of heads and tails
= 22 - 4.4
= 17.6

You use substitution to solve a system of equations and, after simplifying the equations, end with an expression that says 0 = 4. What does that say about the the lines and about the number of solutions to the system?
Sample Response: Since the statement is false, there are no solutions to the system of equations. This also indicates that the lines are parallel.
Check all that you included in your response.
□ The equation is false.
□ False equations indicate no solution.
□ No solution indicates a system with parallel lines.
Hope this helps!
Answer:
Check the first two.
Step-by-step explanation:
Since the statement is false, there are no solutions to the system of equations. This also indicates that the lines are parallel.

Step-by-step explanation:
Evaluate 3z- 3 when z=7
a 34
b 21
c 18
Answer: C (18)
Step-by-step explanation: If we plug in 7 for z, 3 times 7 is 21. 21-3=18.
Answer:
C
Step-by-step explanation:
Since z = 7 the equation would be 3(7) - 3
You would multiply 3 with 7 and get 21
Then you would subtract 3 from 21 and get 18

Answer:
x - (x*0.1)
Step-by-step explanation:
A percentage is just a fraction/decimal. you'll get 10% of the number with the equation in parentheses, and we need to do that first. then we need to take the original price and subtract 10%

....... m
Step-by-step explanation:
For no. 3
x - 3 = 3 - x
x + x = 3 + 3
2x = 6
x = 6 / 2
x = 3
For no. 4
3(x + 4) = 3x + 4
3x + 12 = 3x + 4
3x - 3x = 4 - 12
0 = - 8
Melanie spent four hours babysitting. She charges $16 up front and then an additional charge per hour. The total amount she earned can be represented by the expression $4x + $16. What expression represents the amount she earns each hour?
Please give me the expression.. if u just say i don't know i will report ;)
Answer:
She earns $4 x is representing the hours.
Step-by-step explanation:
16 is the charge up front.
I can infer that the additional charge is $4 because x represents the hours because we don't know how many hours she's going to spend there.

2. Write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. Show all your work, including the points used to determine the slope and how the equation was determined.
Answer:
y=x
Step-by-step explanation:
By using the (y2-y1)/(x2-x1), you can find y=mx+b
Points: (30,30) and (60,60)
(60-30)/(60-30)= 30/30=1
Your m value (slope) is 1.
For the y-intercept, your value is 0
The full answer is y=x
As per linear equation, the required equation of the given graph is y = x.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."
Here, the graph is a straight line.
Therefore, the equation of the given graph must be a straight line.
Again, the graph passes through points (30, 30) and (60, 60).
Therefore, the slope(m) of the given straight line is
[tex]= \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\= \frac{60-30}{60-30}\\ = \frac{30}{30}\\ = 1[/tex]
The graph of the straight line passes through the point (30, 30).
Putting this value in the standard equation(y = mx + c), we get:
30 = (1)(30) + c
⇒ c = 0
Therefore, the y-intercept of the straight line is 0.
Now, the required equation of the straight line is
y = mx + c
⇒ y = (1)x + 0
⇒ y = x
