Use the confidence level and Sample data to find the margin of error E. Round your answer to the same number of decimal places a
Ivenika [448]

Answer:

A) 2.6 mm Hg

Step-by-step explanation:

Margin of error = critical value × standard error

ME = CV × SE

n > 30, so we can approximate CV with a normal distribution.  At P = 94%, CV = 1.88.

SE = σ / √n

SE = 13.5 / √92

SE = 1.41

So the margin of error is:

ME = 1.88 × 1.41

ME = 2.6

What is the equation of the line that has a slope of 4 and passes through then point (3,-10)?
Fynjy0 [20]
<h3>♫ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Substitute the x and y values into the equation:

y = mx + c

'm' is the slope, which we know is 4

-10 = 4(3) + c

- 10 = 12 + c

c = -22

The equation is y = 4x -22

Find p(0),p(1),p(-1) and p(2) of the 3x(x-2) <br><br>​
Effectus [21]

Answer:

<u>make x→0</u>

p(0)=(0)^{2}-3(0)+2

→ p(0)=0+0+2

→p(0)=2

------

<u>Replace x→-1</u>

p(-1)=(-1) ^{2} -3 (-1)+2

→ p(-1)=1-3+2

→ p(-1)=0

----------

<u>Now make x→2</u>

p(2)=(2) ^{2} -3(2)+2

→ p(2)=4-6+2

→ p(2)=0

Answer:-2,0,0

-----------

hope it helps...

have a great day!!

Answer:

Greatest population density: Denmark

Smallest population density: The U.S.

Step-by-step explanation:

Population density = population / area

So let's find the population density of each country

For U.S

Population: 272,648,000

Area: 9,364,520 sq km

Population density: 272,648,000/9,364,520=29.1 ( rounded to the nearest tenth )

So the population density of the U.S is 29.1 people per sq km

For Denmark

Population: 5,248,000

Area: 42,077

Population density: 5,248,000/42,077=124.7 ( rounded to the nearest tenth )

So the population density of Denmark is 124.7 people per sq km

For Ghana

Population: 18,339,000

Area: 237,533

Population density: 18,339,000/237,533=77.2 ( rounded to the nearest tenth ).

So the population density of Ghana is 77.2 people per sq km

Now that we have calculated the population density of each country let's look back at the question

Which country has the greatest population density? Which country has the least?

Looking at the population densities we can conclude that Denmark has the largest population density at 124.7 people per sq km and the U.S. has the smallest population density at 29.1 people per sq km
