Answer:

20

Step-by-step explanation:

He's going to need a very sharp pencil to cross out the people he cannot afford to invite but would like to.

Equation

y = 33 + 1x

y = 42

42 = 33  + x

Solution

42 = 22 + x               Subtract 22 from both sides.

42 - 22 = 22 -22 + x    

20 = x

This means that if each extra person costs $1.00 then he can invite 20 more people (20 * 1 = 20)

What are the possible numbers of positive, negative, and complex zeros of f(x) = x6 + x5 + x4 + 4x3 − 12x2 + 12?
gladu [14]
As per Descartes Theorem, a polynomial of degree n (n is the highest exponent of a polynomial) has n roots (or number of zeros) be it positive, negative, real or complex.

in f(x) = x⁶ + x⁵ + x⁴ + 4x³ − 12x² + 12, the highest degree is 6, then it has 
a total of 6 zeros, positive, negative, real or complex.

jek_recluse [69]

Answer:

The margin of error is given below:

E=z \times \sqrt{\frac{\hat{p}(1-\hat{p}}{n} }

Where:

\hat{p}=\frac{26}{80}=0.325

\therefore E = z \times \sqrt{\frac{0.325(1-0.325}{80} }

                           =z \times 0.0523659

Therefore, the option E = z*6% is correct as it closest to the given answer
