Answer: simple random sampling
Step-by-step explanation:
- A simple random sampling is a sampling method in which individuals are chosen randomly from the population. In this each individual has equal chances to get selected.
- If N is the population size , then for any individual , the chances for getting selected is
.
As per given , the company randomly selects 50 customers directly from the database without applying any further steps and asks them about their level of satisfaction with the company.
Thus , the sampling technique used here is simple random sampling.
Answer:
The initial value of the function is <u>2</u>
The base of the function is <u>3</u>
The function shows exponential <u>growth</u>
Step-by-step explanation:
f(x) = 2(3^x)
Exponential functions are those with the following equation:
y = a*b^x
where a ≠ 0, b > 0 and b ≠ 1 and x is a real number.
<em>a</em> is the y-intercept and <em>b </em>is the base.
The initial value of the function is the same as the y-intercept
If <em>a</em> is positive, the function growth. If <em>a</em> is negative, the function decay
Answer:
a) 1/27
b) 16
c) 1/8
Step-by-step explanation:
a) 
One of the properties of the exponents tells us that when we have a negative exponent we can express it in terms of its positive exponent by turning it into the denominator (and changing its sign), so we would have:
And now, solving for x = 9 we have:
b) 
This is already a positive rational exponent so we are just going to substitute the value of y = 8 into the expression
c) 
Using the same property we used in a) we have:
And now, solving for z = 16 we have:
Answer:
pit it on -4 because your reflecting it on x
The computation shows that the area of the kitchen that's in the home in square feet is 50ft².
<h3>How to calculate the area?</h3>
It should be noted that an area of a rectangular space is calculated by multiplying the length by the width.
In this case, the area of the kitchen will be:
= 5ft × 10ft
= 50ft²
