Answer: n = 600.25 ≈ 601 ( sample size)

the minimum sample size of the adults in United State who have sleep deprivation  is 601

Step-by-step explanation:

Given that;

the confidence level = 95% = 0.05

the Margin of error E = 4% = 0.04

∴  level of significance ∝ = 1 - C.L

∝ = 1 - (95/100)

= 0.05

Z∝/2 = 0.05/2 = 0.025

Z-critical value at 95% confidence level is OR level of significance at 0.025 = 1.96 (z-table)

Now to calculate the sample size, we say

n = (Z(critical) / M.E )² P ( 1 - P)

now we substitute

n =  (1.96 / 0.04)² × 0.5 ( 1 - 0.5)

n = 2401 × 0.5 × 0.5

n = 600.25 ≈ 601

Therefore the minimum sample size of the adults in United State who have sleep deprivation  is 601

Using the formula for the margin of error, it is found that a sample of 601 is needed.

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

95% confidence level

So [tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].

In this problem:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.04 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]

[tex]0.04\sqrt{n} = 1.96(0.5)[/tex]

[tex]\sqrt{n} = \frac{1.96(0.5)}{0.04}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.96(0.5)}{0.04}\right)^2[/tex]

[tex]n = 600.25[/tex]

Rounding up, a sample of 601 is needed.

Step-by-step explanation:

Given

A [tex]\triangle GHJ[/tex] in which

[tex]\angle GHJ = 90^\circ[/tex]

Hypotenuse = 10

Length of another side = 5

To find:

HJ = ?

Solution:

Kindly refer to the image attached in the answer area.

We know that there are only 3 sides in a triangle.

We are given hypotenuse is 10.

i.e. GJ = 10

To find HJ, Base = ?

So, we are given the side length of GH, perpendicular i.e. 5.

Kindly refer to attached image for further details.

Let us use Pythagorean theorem here.

According to Pythagorean theorem:

[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow GJ^{2} = GH^{2} + HJ^{2}\\\Rightarrow 10^2=5^2+HJ^2\\\Rightarrow HJ = \sqrt{100-25}\\\Rightarrow \bold{HJ = \sqrt{75}}[/tex]

Answer:

The absolute value for x = 1/6

Step-by-step explanation:

Leave |x + 3| alone

2/3|x + 3| = 11/6 + 1/2 ➡ 2/3|x + 3| = 14/6

|x + 3| = 14/6 ÷ 2/3 ➡ |x + 3| = 7/2 now we write two equations

x + 3 = 7/2 or x + 3 = -7/2 first we subtract 3 from all

x = 1/6 or x = -13/6 since we are asked to find the absolute value, the answer would be 1/6

Answer: y = -2/5x -4

Step-by-step explanation:

First we can notice that the line is not going through the origin but is is going through the y-intercept which is -4.In this case the the equation of the line has be in slope intercept form as if  y=mx +b where only m and b is indicated and  m is the slope and b is the y intercept. So since we already know the y intercept is -4 we need to find the slope using  the points on the line.

The points (0,-4) and ( -5,-2)   lies on the line and we could use them to find the slope. To find the slope,we need to find the change in the y coordinates and divide it by the change in the x coordinates.

-4 -(-2) =  -2

0 - (-5) = 5      

slope:  -2/5

So since the slope is -2/5 and the y intercept is -4 then we will have the equation,

y= -2/5x - 4

Answer:

The length of the curtain is 10.625 feet

Step-by-step explanation:

The length of the curtain to cover one side of the room depends on the shape of the room

Given a room shape of a square, we have;

Perimeter = 4 × Side length of the room

Length of the curtain = Side length of the room

Therefore;

Perimeter = 4 × Length of the curtain

42.5 feet = 4 × Length of the curtain

Length of the curtain = (42.5 feet)/4 = 10.625 feet

The length of the curtain = 10.625 feet.

Answer:

(x-12)/5

Step-by-step explanation:

Answer:

f⁻¹(x) = (x - 12)/5

Step-by-step explanation:

To find the inverse of f(x), you have to switch the places of the x and y.  You then have to rearrange the equation so that it is equal to y.

f(x) = 5x + 12

x = 5y + 12

x - 12 = (5y + 12) - 12

x - 12 = 5y

(x - 12)/5 = 5y/5

(x - 12)/5 = y

f⁻¹(x) = (x - 12)/5

Answer:

x=-1/3 or x = -3/2

Step-by-step explanation:

6x²+11x+3=0

divide through by 6

x² +11x/6 + 3/6 =0

collect like terms that is those with x should be left on one side nd the one without x should be on the other side

x² +11x/6 = -1/2

add the square of the half of the co efficient of B i.e 11x/6 to both sides

(x+11/12)² = 121/144 -1/2

(x+11/12)² = 121-72/144

square root of both sides

x+11/12 =+or - √49/144

x= -11/12 ± 7/12

x= -1/3 or x= -3/2

Answer:

25) true

for example if x is -3 then x^2 will be +9

Step-by-step explanation:

The level of the pond is dropping each day by 4 cm.  7 days passed, and each day it was dropping at a constant rate.  In order tto find how many centimeters the level of the pond dropped in 7 days, you have to multiply the days passed by the amount dropped each day.

So, 7 days times 4 cm. a day= 28 centimeters dropped.

Answer:

Step-by-step explanation:

The shape is made up of a semicircle and a right angled triangle.

Perimeter of the shape = perimeter of a semicircle + perimeter of the right angle triangle.

Since perimeter of a circle = 2πr

Perimeter of a semicircle = 2πr/2 = πr wherr r is the radius

r = 10in/2 = 5in

Perimeter of the semicircle = 5π in

Perimeter of a triangle = s1+s2+s3 where s1, s2 and s3 are the sides of the triangle.

We only have 2 sdies of the triangle, hence we need to get the third side using pythagoras theorem.

let s1 = 10in, s2 = 6in

10² = 6²+s3²

s3 = √10²-6²

s3 = √100-36

s3 = √64

s3 = 8in

Perimeter of the triangle = 10in+6in+8in = 24in

Perimeter of the shape = (24in + 5π in) - 10in (10 in was subtracted since it is common to both shapes)

Perimeter of the shape = (14+5π )inches
