The inequality built is:
Solving the inequality, it is found that Myesha needs to buy at least 41 sets.
--------------------
- The restaurant currently has 248 knives.
- Each set on sale contains 10 knives, thus, for s sets, 10s knives are added.
- If s sets are bought, the total number of knives is:
The restaurant needs at least 657 knives, thus:
The inequality is:
The solution is:
Thus, Myesha needs to buy at least 41 sets.

z= r(cosθ+i sinθ) is the required polar form where, r = √41 and θ =π-
Step-by-step explanation:
Given,
-4+5i is a complex number.
To find the polar form.
Formula
z=x+iy
r² = mod of (x²+y²)
θ =
So, the polar form will be z=r(cosθ+i sinθ)
Now,
r² =(-4)²+5² = 41
or, r = √41
θ =π- [ since the point is in second quadrant]
Hence,
z= r(cosθ+i sinθ) is the required polar form where, r = √41 and θ =π-
"Have only 1 and itself as a factor" is definition of prime
so each factor must be prime
let ssay 2
2 is prime
2^4=16
a number is 16
Answer:
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Step-by-step explanation:
We have given,
The sample size n=42
The sample mean
The population standard deviation
Let be the level of significance = 0.05
Using the z-distribution table,
The critical value at 5% level of significance and two tailed z-distribution is
The value of margin of error is
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
