These were the results:
yes, yes, yes, no, yes, no, yes, yes, no, yes, no, yes

a. Estimate the proportion of all shoppers who were happy with their experience that day.

Answers

Answer 1

Answer:

2/3

Step-by-step explanation:

Probability=number of favourable outcomes/number of possible outcomes

P(customers who were happy with their experience)= 8/12 = 2/3

two-third of total customers (12 people) were happy with their experiences.

A clothing store is having a sale on shirts and jeans. 4 shirts and 2 pairs of jeans cost $64. 3 shirts and 3 pairs of jeans cost $72. What is the cost of one shirt? What is the cost of one pair of jeans

Answers

Answer:

Shirt:8 ; jsans:16.

Step-by-step explanation:

Let’s shorten these terms: shirt=s ; jean=j.

3s+3j=72

4s+2j=64 => =2j=64-4s => j=(64-4s):2 => j=32-2s

3s+3j=72 => (instead of j we write 32-2s=> 3s+3*(32-2s)=3s+96-6s=72

=> -3s=72-96
-3s=-24

s=24:3

s=8.
=> j=32-2s => j= 32-16 => j=16.

[tex]y = 135[/tex]

Answer:

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos43° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{75}{y}[/tex] ( multiply both sides by y )

y × cos43° = 75 ( divide both sides by cos43° )

What is the range of the function g(x) = |x – 12| – 2?.

Answers

The range of the given function is [-2,∞).

what is the range of a function?

the range is the complete set of all possible values of the dependent variable say 'y'.

given function is:  f(x)=  |x – 12| – 2

f(x) = x-14  ∀ x≥12

f(x) = -x+10 ∀ x < 12

value of the above function at x=12 will be -2 means the minimum value of the function will be -2.

now, from the graph, we can see that f(x) is leading to infinity

so the range will be [-2,∞).

therefore, The range of the given function is [-2,∞).
