Answer: B is correct

Step-by-step explanation:

if you do 2 ÷ 5 you get 0.4. But that isn't an option. So, the only other possibility would be -2 ÷ 5 which gives us -0.4, and that makes sense.

I'm not the greatest at explaining this one but hopefully, this helps!

Over the course of a week, an environmental activist randomly stopped 1,200 people on the street and asked whether they were wil

sdas [7]

Sample Size = n = 1200
Number of people who are willing to pay higher = x = 708

Proportion of people who are willing to pay higher = p = $\frac{708}{1200}= \frac{59}{100}=0.59$

Confidence Level = 99%
Z Value = z = 2.58

The confidence interval about a population proportion can be calculated as:

$(p-z \sqrt{ \frac{p(1-p)}{n} }, p+z \sqrt{ \frac{p(1-p)}{n} })$

Using the values, we get:

$(0.59-2.58 \sqrt{ \frac{0.59(0.41)}{1200} } ,0.59+2.58 \sqrt{ \frac{0.59(0.41)}{1200} }) \\ \\ 
(0.553,0.627)$

Thus, at 99% confidence level, the estimated proportion of people willing to pay higher prices for gas in order to protect the environment lies between 0.553 and 0.627.

Help me do examples for a function and a non function

bekas [8.4K]

Answer:

{(1,2) (3,4) (5,6)} and {(1,2) (1,4) (5,6)}

Step-by-step explanation:

you really want to think of a function as a vending machine. if you press B12 on a vending machine because thats where the chips are, only the chips should come out. in a function, the input value aka x (B12, what youre putting in) should only have one output value aka y, (the chips)

an example of a function would be {(1,2) (3,4) (5,6)}

an important thing to remember is that one output value can belong to multiple input values. there can be chips (output) in both B12 and C12 (inputs) BUT as i said before, there CANNOT be two outputs for one input. B12 cannot give you both chips and a drink.

using this, another example of a function would be {(1,2) (3,2) (5,2)}

an example of an non function would be {(1,2) (1,4) (5,6)} because x, the input value, has multiple output values which is not possible. the output of 1 can not be 2 and 4 at the same time which we can see in the (x,y) coordinates.
