Answer:
Total amount paid = 20 + 15x
11 months
Step-by-step explanation:
Annual fee = $20
User charge per month = $15
Number of months = x
Total amount paid = 20 + 15x
Felix prepaid = $185
Total amount paid = 20 + 15x
185 = 20 + 15x
Subtract 20 from both sides
185 = 20 + 15x
185 - 20 = 20 + 15x - 20
165 = 15x
Divide both sides by 15
x = 165 / 15
= 11
x = 11 months

Answer:
Step-by-step explanation:
Given that a simple random sample of 40 ten-gram portions of the food item is obtained and results in a sample mean of x overbarequals2.5 insect fragments per ten-gram portion.
a) By central limit theorem for samples randomly drawn with large sample sizes (atleast 30) the sample mean follows a normal distribution irrespective of the original distribution it belonged to.
b) Mean of X bar = Sample mean = 5
Std error of x bar = s/sqrt n = ![\frac{289}{\sqrt{40} } \\=45.695](https://tex.z-dn.net/?f=%5Cfrac%7B289%7D%7B%5Csqrt%7B40%7D%20%7D%20%5C%5C%3D45.695)
c) P( x bar >5.8) = P(Z>
