You know $89.64 is 65%
<span>and you want to find out 100% </span>
<span>so: </span>
<span>??? = 100% </span>
<span>89.64 = 65% </span>
<span>89.64 x 100 = 8964 </span>
<span>8964 : 65 = 137.90769 </span>
<span>So you know 100% are 137.90769 </span>
<span>Then you round up to 2 decimals </span>
<span>So the answer is, before the sale the shoes cost $137.91 </span>
Answer: C plz brainliest
Step-by-step explanation:
Cuz if x is replaced for 646

Since it said approximately it is 21.758
<h3>
Answer:</h3>
-36
<h3>
Step-by-step explanation:</h3>
The applicable rule of exponents is ...
... (a^b)^c = a^(b·c)
Here, you have a=m, b=?, c=1/3, b·c = -12, so you can write ...
... b·(1/3) = -12
Multiply by 3.
... b = -36
The exponent of m inside parentheses is -36.
Using margin of error, it is found that increasing the sample size results in a smaller sampling error.
The equation for the <em>margin of error</em> is given by:
In which:
- c is the critical value according to the distribution used.
- s is the standard deviation, either of the sample or of the population.
From the equation, it can be noted that the margin of error is inversely proportional to the square root of the sample size, hence, increasing the sample size results in a smaller sampling error.
