4z^3 + 5z^2 + z
<span>Well that</span> would be it... <span>not</span> much can be done considering the exponents of the variable :)
An item, x, is marked up 40% and now costs $49.99
40% is 0.40
1 times any number will be the same number so we'll use that to add on the original price to the amount of increase
(1+0.40)x=49.99
x=49.99/1.4
x=35.71 so D is the answer
A) The original claim in symbolic form is; p > 0.50
B) The Null Hypothesis is;
H₀: p = 0.50
Alternative Hypothesis is;
H_a: p > 0.50
<h3>How to identify the hypothesis claim?</h3>
We are given;
Sample size; n = 576
Sample Proportion; p^ = 59% = 0.59
A) The percentage of 59% represents the proportion of a sample and thus we are making a claim about the population proportion p in the hypotheses.
We claim "most of the adults", which indicates more than 50% or 0.50. Thus, the claim in symbolic form is; p > 0.50
B) The Null Hypothesis is;
H₀: p = 0.50
Alternative Hypothesis is;
H_a: p > 0.50
