Answer:
250g= 3g
Step-by-step explanation:
The first step is to convert the kg to g
5kg
= 5 × 1000
= 5000g
5000g= 60g
500g= 6g
250g = 3g
Hence the t's simplest form is 250g= 3g
Using the z-distribution, it is found that a sample size of 3,385 is required.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
The margin of error is:
In which:
- is the sample proportion.
In this problem, we have a 98% confidence level, hence, z is the value of Z that has a p-value of , so the critical value is z = 2.327.
We have no prior estimate, hence is used, which is when the largest sample size is needed. To find the sample size, we solve the margin of error expression for n when M = 0.02, hence:
n = 3,385.
A sample size of 3,385 is required.

Answer:
negative
Step-by-step explanation:
that is a negative slope .
Answer:
b
Step-by-step explanation:
1. the function will approach negative infinity as x approaches neg/pos infinity because -x^4 (highest power) will result in both ends pointing down. this rules out a and d.
2. skip the Maxima/minima part
3. to test for zeroes, list all possible zeroes using rational zero theorem. then use synthetic division to test out the differing zeroes between b and c.
we find -5 leaves us with remainder of 0, so it is a zero where as -7 leaves us with some remainder that isn't 0, so it is not a zero.
the only option with the function approaching negative infinity with a zero at -5 is b
