Consider a 95 percent confidence interval constructed for the difference between two population
proportions PR and Ps. The interval for PR - Ps is given as (-0.05, 0.15). Which of the following is an
appropriate interpretation of the confidence level?
In repeated random sampling with the same sample size, êr - Ộs will be contained in
the interval approximately 95 percent of the time.
In repeated random sampling with the same sample size, PR will be contained in the
interval approximately 95 percent of the time.
In repeated random sampling with the same sample size, Ôr will be contained in the
interval approximately 95 percent of the time.
The probability is 0.95 that the difference in the sample proportions PR - Ổs is between
-0.05 and 0.15
In repeated random sampling with the same sample size, approximately 95 percent of the
intervals will capture the difference in population proportions, PR - Ps.

x=4

Step-by-step explanation:

you have to get x on one side so x=4

Answer:

x=4

x=4

Answer:

x=39

Step-by-step explanation:

Answer:

it would be less than

Step-by-step explanation:

so it would be this <

The magnitude of the number 6.209 is less than the number 6.29 thus the sign of inequality will be < as 6.209 < 6.29.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given numbers,

6.209 and 6.29

Since, 6.209 - 6.29 = -0.081

Thus, 6.209 < 6.29.

Hence "The magnitude of the number 6.209 is less than the number 6.29 thus the sign of inequality will be < as 6.209 < 6.29".

Step-by-step explanation:

Answer:

80 square yards

Step-by-step explanation:

We know we have a width of 8 yards and a perimeter of 36.

how I figured it out was:

36=(8*2) * (x*2)

8*2=16

36-16=10

So now we know the length and width.

area of a rectangle is lw (length * width)

10*8=80.

Answer:

Answer:

Each person will get 3 pieces

Step-by-step explanation:

First you separate each item in 4 pieces. Then you get 12 pieces. Since 12 divided with 4 is 3, the answer is 3.

We want to draw a model that shows 3 items being divided equally for 4 people, we will see that each person receives 0.75 of an item.

Here you just need to create an area that represents 3 elements, then replicate that area but this time with 4 sections, so we can see how much each of the 4 sections takes from the 3 elements.

The model can be seen below. (this is just an example, you should do it with a ruler to have a proper model).

Now to see how much each person haves we just take the quotient:

3/4 = 0.75

Each person receives 0.75 of an item.

Answer:

What’s The question?

Answer:

Direct variation, by definition, has the form shown below:

y=kx  

Where k is the constant of proportionality.

Given the information in the problem, you can find k:

7=3k

k=7/3

Now you can find y when x=7 as following:

y=(7/3)x

Substitute values.

y=(7*7)/3

y=49/3

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = ax² + bx + c

~~~~~~~

(4, - 2), (8, 6), (2, 0)

a(4²) + b(4) + c = - 2

a(8²) + b(8) + c = 6

a(2²) + b(2) + c = 0

16a + 4b + c = - 2 .............. (1)

64a + 8b + c = 6 ............... (2)

4a + 2b + c = 0 ................. (3)

a = 0.5 ; b = - 4 ; c = 6

y = 0.5x² - 4x + 6

Part A: (0, 6), (6, 0)

Part B: (0,6)

Part C: (6, 0)

Part D: [ 4, ∞ )

The quadratic function has the form f(x) = ax² + bx + c, where a, b, and c are non-zero values, and the calculation of the values can be defined as follows:

vertex point of graph function= (4,-2)

points=  (8,6) and (2,0)

Using the formula of a quadratic function:

[tex]y = ax^2 + bx + c[/tex]

putting the value into the above-given formula:

[tex]\to (4, - 2), (8, 6), (2, 0)\\\\\to a(4^2) + b(4) + c = - 2\\\\\to 16 a + 4b + c = - 2.........................(a)\\\\\to a(8^2) + b(8) + c = 6\\\\\to 64a + 8b + c = 6......................................(b)\\\\\to a(2^2) + b(2) + c = 0\\\\\to 4a + 2b + c = 0................................(c)\\\\[/tex]

Computing the value of a,b, and c:

[tex]\to a = 0.5\\\\ \to b = - 4 \\\\ \to c = 6\\\\[/tex]

Putting the value of a, b, and c values into the quadratic function:

[tex]\to y = 0.5x^2 - 4x + 6[/tex]

So, the calculated points are:

Part A: (0,6)

Part B: (2,0) and (6,0)  

Part C: x>4

Part D: positive the parabola upwards

Answer:

8<n+1/5<98

Step-by-step explanation:

Answer:

80%

Step-by-step explanation:

0.75 ⇒ 100%

0.15 ⇒ x%

0.75x = 100·(0.15)

0.75x = 15

x = 15/(0.75)

x = 1500/75

x = 20%

100% - (discount) = x%

100% - (discount) = 20%

discount = 100%-20%

discount = 80%

Step-by-step explanation:

It might want a simplified version of the fraction, so the answer for that one could be 4/5. I hope this helps :)

The percent of the pencils in the pack are black is,

⇒ 80%

And, The fraction of the pencils in the pack is black is,

⇒ 24 / 30

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Ms. Cathy bought a package of pencils.

And, Out of every 10 pencils, 8 are black. .

Since, There are 30 pencils in the pack,

Hence, The percent of the pencils in the pack are black is,

⇒ 24 / 30 x 100

⇒ 2400 / 30

⇒ 80%

And, The fraction of the pencils in the pack is black is,

⇒ 8 / 10 = x / 30

⇒ 240 = 10x

⇒ x = 24

Thus, The fraction of the pencils in the pack is black is,

⇒ 24 / 30

Thus, The percent of the pencils in the pack are black is,

⇒ 80%

And, The fraction of the pencils in the pack is black is,

⇒ 24 / 30
