The counter top is 48 square feet (16x3) and there are 4.45935 square meters in 1 square foot... So I think about $90... I Hope this helps :)
11+13= 24
13-11= 2
The numbers are 13 and 11.
I hope this helps!

The answer to this problem is 555.4
Sample is the 3 selected customers; And population is all customers
According to the statement
we have given that a shopkeeper asks 3 customers to taste the chocolate icecream.
And we have to identify the sample and population.
So, A definition of sample is that a
A sample is an outcome of a random experiment. When we sample a random variable, we obtain one specific value out of the set of its possible values. That particular value is called a sample.
And a Population is defines as the is a discrete group of people, animals or things that can be identified by at least one common characteristic for the purposes of data collection and analysis.
So, according to definition Sample is the 3 selected customers; And population is all customers.

Complete question :
The 100m dah times in the girl's track meet were normally distributed with a mean of 13 seconds and a standard deviation of 0.3 seconds.
Lana finished the race in 13.2 seconds . If 84 other girls ran in the event, approximately how many runners did she beat?
Answer:
21 runners
Step-by-step explanation:
Mean, μ = 13 seconds
Standard deviation, σ = 0.3
Lana's race time = 13.2
We find the proportion of runners who had race time above 13.2 ;
Proportion of who had race tune above 13.2
P(x > 13.2)
Obtain the Zscore
Zscore = (x - μ) / σ
Z = (13.2 - 13) / 0.3
Zscore = 0.2 / 0.3 = 0.6667
P(Z > 0.6667) = 0.25239 (Z probability calculator)
This is about 0.25239 * 100 = 25.24% = 25% (nearest percent)
Hence, Number of runners Lana beat = 25% of total runners ;
0.25 * 84 = 21
Hence, Lana beat about 21 runners
