The mayor of a town has proposed a plan for the annexation of a new community. A political study took a sample of 10001000 voter
Reil [10]

Answer:

We accept H₀

p-value = 0,1618

Step-by-step explanation:

We are going to solve a one tail proportion-test ( right tail)

We assume Normal distribution

Sample population 1000

Political strategist to test  wants to test:

Null hypothesis                             H₀           p = p₀       or   p = 26 %

Alternate hypothesis                    Hₐ           p > p₀        or  p > 26%

We assume CI  90 % then

α = 10 %     α = 0,1    and  z score for α = 0,1  is critical value

z = 2,32          ( note  2,32 is z score for α = 0,1017 "good approximation")

To compute z(s)

z(s)  =  ( p -p₀ ) / √ p₀q₀/n

z(s)  =  ( 0,29 - 0,26 ) /√ 0,26*0,74/1000

z(s)  = 0,03 / 0,014

z(s) = 2,14

We compare z(s) and z(c)

z(s) < z(c)

2,14 < 2,32

z(s) is in the acceptance region we accept H₀

The p-value for z(s) is from z-table

p-value = 0,1618

On the first day of school, the cafeteria serves hot dogs and hamburgers together. The cafeteria serves hot dogs every 6th schoo
kumpel [21]

Answer:

The Answer is 12 days or times.

Step-by-step explanation:

The LCM of 6 is 3 and 2, the LCM of 4 is 2 and 1, so we multiply 3 by 2 and 4 by 2 together to get 12, which is the number of days or times.

PLEASE HELP!!! ASAP I don't understand this!!!
Paladinen [302]

Answer by JKismyhusbandbae: So this is really simple. You are probably making this out harder than it needs to be. Consider the set of ordered pairs {(-1,0), (4,-5), (6,-6), (9,11), (10,14)}.  This set of ordered pairs is a function because for each value of x there is one and only one y-value.  This means that the x value never repeats.  Therefore any function is a function when the x value never repeats.

Looking at the table we want to find all it's ordered pairs: (0,4), (1,2), (2,3), (3,9), (4,1).

F(2) is 3 so when x equals 2.

So the ordered pair is (2,3) 2 is the x value and the f(2) is 3.

The ratio of adult dogs to puppies on monday was 3:2. There were 12 puppies there that day. Tuesday, 15 adult dogs were at the p
Svetlanka [38]

Answer:

3

Step-by-step explanation:

The ratio of adult dog to puppies is 3:2

There were 12 puppies that day

Number of adult puppies can be calculated as follows

= 3/2× 12

= 3 ×6

= 18

There were 15 adult dogs in the park on Tuesday

Hence the difference can be calculated as follows

= 18-15

= 3

Find the following equation
adoni [48]

Answer:

y=\frac{-1}{2}x+7

Step-by-step explanation:

Slope intercept form: y=mx+b when m is the slope of the line and b is the y-intercept (the y-coordinate of the point the line crosses the y-axis)

<u>1) Find the slope (</u>m<u>)</u>

m=\frac{y_2-y_1}{x_2-x_1} when the points are (x_1,y_1) and (x_2,y_2)

We can use any two points that the table gives us to plug into this equation. For example, we can use the points (14,0) and (0,7):

m=\frac{0-7}{14-0}\\m=\frac{-7}{14}

Simplify the fraction

m=\frac{-1}{2}

So far, our equation looks like this:

y=\frac{-1}{2}x+b

<u>2) Find the y-intercept (</u>b<u>)</u>

The y-intercept is the y-coordinate of the point the line crosses the y-axis, or in other words, it's the value of y when x is equal to 0.

Looking at the table, we can see that y is equal to 7 when x is equal to 0, so, therefore, b=7.

Now, this is our final equation after plugging in m and b:

y=\frac{-1}{2}x+7

I hope this helps!
