Answer:

\huge\boxed{\sf 46.2\%}

Step-by-step explanation:

Prediction = 19 throws

Actual = 13 throws

<h3><u>Percent Error:</u></h3>

\displaystyle =\frac{Predication -Actual}{Actual} \times 100 \%\\\\= \frac{19-13}{13} \times 100 \%\\\\= \frac{6}{13} \times 100 \%\\\\= 0.462 \times 100 \%\\\\= 46.2\%\\\\\rule[225]{225}{2}

Y = x2 + 12x + 30<br> 8x − y = 10
faltersainse [42]
So you need the solve for x and y ?

from 8x-y = 10,
y = 8x -10

Plug this in other equation.
8x-10 = x^2 +12x + 30

Re-arrange and combine like terms,
x^2 +12x -8x +30+10 = 0
x^2 +4x +40 = 0

This does not have any real solutions.
So there are no real values of x and y satisfying the 2 equations.

Are you sure the question is correct? or if this question belongs to complex numbers topic?

2v2 -5v +3 = 0 how did I do this?
anzhelika [568]
2v2 -5v +3 = 0 \\ \\\Delta = b^{2}-4ac = (-5)^{2}-4*2*3= 25-24=1\\ \\v_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{5- \sqrt{1 }}{2*2}=\frac{5- 1}{4}= \frac{4}{4}=1\\ \\v_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{5+ \sqrt{1 }}{2*2}=\frac{5+1}{4}= \frac{6}{4}=\frac{3}{2}=1\frac{1}{2}

Write the inverse function for the function, ƒ(x) = x + 4. Then, find the value of ƒ -1(4). Type your answers in the box.
lesya [120]

The inverse is:

f^{-1}(x) = x-4

Further explanation:

Given function

f(x) = x+4

<u>Step 1: Replacing f(x) with y</u>

y = x+4

<u>Step 2: Replacing x with y and y with x</u>

x = y+4

<u>Step 3: Solving the equation for y</u>

x = y +4\\x -4 = y+4-4\\y = x-4

<u>Step 4: Replacing y with f-1(x)</u>

f^{-1}(x) = x-4

So, the inverse is:

f^{-1}(x) = x-4
