Rachel’s free-throw average for basketball is 60%. How many times do you think she will make a free-throw in her next 50 tries?
Answer:
Rachel will make 30 free-throws!
Step-by-step explanation:
Hello!
I came up with this solution with some easy mental math! If you weren't aware, 60% of 50 is a whole number! Meaning that 60% of 50 is 30. You could even double 50 to make it 100, everyone knows that dealing with percentages with the number 100 make them a whole lot easier!
Back to what I was saying, if you used 100, you would also have to take 60% of 100, which is 60. And then have to divide 60 by 2 because you doubled the 50! Giving you 30 free-throws, which is the correct answer!
Hope this helped! Let me know if you have any further questions! :)
if f(x) =7x+5/3-x, then show that fof power -1(x) is an identity function
If f(X)= 7x +5/3 - x =6x +5/3
y= 6x +5/3
6x= y-5/3
f^-1(y)=x=(y-5/3)/6
So we can write
f(f^-1(y))= f((y-5/3)/6) = 6 (y-5/3)/6 +5/3= y-5/3+5/3= y
The same result can be obtained for f^-1(f(x))=x
If the function is f(x)= 7x +5/(3-x) then it is not invertible since it is not injective (pictures)
C=(3x-5)^2-36x^2
tìm x
Answer:
C = -27x^2 - 30x + 25
Step-by-step explanation:
C = (3x - 5)^2 - 36x^2
~Use FOIL
C = 9x^2 -30x + 25 - 26x^2
~Simplify
C = -27x^2 - 30x + 25

Jerimiah records lap times at the track meet on Saturday. He records a time of 85 seconds for Jennifer's lap, but she really completed the lap in 84.25 seconds.
What is the approximate percentage of error in Jerimiah's measure?
Answer:
I'm not sure. What I would do, though, is find the difference of the two times and then find the percentage of that within the original time. So the difference is .75. So the percentage would be .25%. Just an educated guess.

Order 0.5, -1/7, -0.2, and 1/3 from least to greatest.
Hey there! I'm happy to help!
Let's convert the decimals to fraction form.
0.5=5/10=1/2
-1/7
-0.2= -2/10= -1/5
1/3
We know that the bigger the number in the denominator, the smaller the fraction is if the numerators are all the same.
First off, we have the negative numbers which are smaller than the other numbers. We have -1/7 and -1/5. We know that the 1/5 is a bigger fraction, but it is negatively bigger, so that is going to be the lesser number.
-1/5, -1/7
And with our bigger ones, we have 1/3 and 1/2. 1/2 is the bigger number here, so that will be the last one. Let's also be sure to convert back to our original forms! Here is our order :
-0.2, -1/7, 1/3, 0.5

Where is the error in the solution below? Explain what the error is and solve the equation correctly. Be sure to check your answer.
Answer:
The error in the question is that in the second line, both sides are not multiplied by x. This causes an imbalance in the equation.
Step-by-step explanation:
[tex]\frac{5}{x}= x-4[/tex]
Multiply both sides by x.
[tex]x(\frac{5}{x}) = x(x-4)[/tex]
[tex]5= x^{2} -4x[/tex]
Subtract 5 from the equations.
[tex]x^{2} -4x-5=0[/tex]
Factorise the equation (Quadratics)
[tex](x-5)(x+1)=0[/tex]
Null Factor Law
[tex]x=5[/tex] or [tex]x=-1[/tex]
Here, we have to go through the equation and correct it:
Starting equation: 5/x = x - 4
Multiply both sides by x:
x * (5/x) = x * (x - 4)
[tex]5 = x^2 - 4x[/tex]
Move all terms to one side to set up a quadratic equation:
[tex]x^2 - 4x - 5 = 0[/tex]
Now, we have a quadratic equation that needs to be solved.
We can solve this quadratic equation using factoring, completing the square, or the quadratic formula.
In this case, let's use factoring:
(x - 5)(x + 1) = 0
This gives you two possible solutions:
x - 5 = 0 --> x = 5
x + 1 = 0 --> x = -1
So, the correct solutions for the equation 5/x = x - 4 are x = 5 and x = -1. The error in your solution was in the step where you multiplied by x; you didn't distribute x properly to both terms on the right side of the equation.
This causes an imbalance in the equation.
