A random sample of 4000 U.S. citizens yielded 2150 who are in favor of outlawing cheesing. Find the point estimate for estimatin

Darina [25.2K]

Answer:

0.5375

Step-by-step explanation:

The point estimate of proportion of all Americans who are in favor of outlawing cheese can be computed as

p=x/n

Here. x is the number of favorable outcomes and n is sample size.

We are given that x=2150 and n=4000, So,

p=2150/4000

p=0.5375.

Thus, the point estimate of proportion of all Americans who are in favor of outlawing cheese is 0.5375.

A new restaurant with 134 seats is being planned. Studies show that 62% of the customers demand a smoke-free area. How many se

zzz [600]

Answer: 100

Step-by-step explanation:

Given : The total number of seats planned in new restaurant =134

The percentage of customers demand a smoke-free area = 62%

It can also be written as $62\%=\dfrac{62}{100}=0.62$

The mean of this binomial distribution will be :-

$\mu=np\\\\\mu=(134)(0.62)=83.08$

Standard deviation:-

$\sigma=\sqrt{np(1-p)}\\\\\Rightarrow\sigma=\sqrt{134(0.62)(0.38)}\approx5.6$

Now, the number of seats should be in the non-smoking area in order to be very sure of having enough seating there :-

$\mu+3\sigma=83.08+3(5.6)=99.88\approx100$

What is the vertex of the equation y = -x 2 + 10x - 28?

Roman55 [17]

Answer:

(5,-3)

Step-by-step explanation:

Rewrite the equation in vertex form

y =-(x-5)^2 - 3

You take the value of -5 (that would be your x value) and change it to the opposite sign -> +5

Then you take -3 (that would be your y value) and take it as it is

therefore the answer is (5, -3)
