The expression for the cost function is cost=60y.
We have given that,
a cup of tea costs 60p.
We have to determine the cost function.
<h3>What is the cost function?</h3>
In mathematical optimization and decision theory, a loss function or cost function is a function that maps an event or values of one or more variables onto a real number intuitively representing some cost associated with the event. An optimization problem seeks to minimize a loss function.
Cost=no of cups(price for one cup)
cost=60y
Therefore the expression for the cost function is cost=60y.

Answer:
explain the difference between a postulate and a theorem:
A postulate is a statement that is to be assumed as true without proof. A theorem is a true statement that can be always proven.(put an example from the module. Idk the module ofc)

Answer:
D. The data are discrete because the data can only take on specific values.
Step-by-step explanation:
<u>Continuous variables</u> are variables that can take on any value in an interval. Examples of continuous variables are length, time, etc.
<u>Discrete variables</u> on the other hand are variables that can only take on specific values.
The durations of movies in minutes<u> can only take on integer values from 0 to 60.</u> Therefore, it is a discrete data.
The correct option is D.
Answer:
SUPER SIMPLE =
if r//s then the two angles which in this case are 110 and 80 should be equal but clearly in this case are not so the the lines r and s arent parallel to each other .
Answer:
51.60% probability that a randomly selected adult has an IQ between 86 and 114.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Find the probability that a randomly selected adult has an IQ between 86 and 114.
Pvalue of Z when X = 114 subtracted by the pvalue of Z when X = 86. So
X = 114
has a pvalue of 0.7580
X = 86
has a pvalue of 0.2420
0.7580 - 0.2420 = 0.5160
51.60% probability that a randomly selected adult has an IQ between 86 and 114.
