Answer:

Step-by-step explanation:

The area A of a circle of radius r is A = πr², where π is often approximated by 3.14.

Here, with the circle diameter being 8, we figure the radius to be half that, or 4.

Then the area of this circle is A = (3.14)(4 in)², or

                                                 A  =  50.24 in²

Answer:

50.24

Step-by-step explanation:

Area = pi*r^2

r = diameter/2

r = 4

Area = pi*4^2

Area = 3.14*16

Area = 50.24

Answer:

\large\boxed{\text{yes,}\ \dfrac{2}{3}}

Step-by-step explanation:

If it's a geometric sequence, then

\dfrac{a_{n+1}}{a_n}=a_{n+1}:a_n=constant

Check:

\dfrac{2}{9}:\dfrac{1}{3}=\dfrac{2}{9}\cdot\dfrac{3}{1}=\dfrac{2}{3}\\\\\dfrac{4}{27}:\dfrac{2}{9}=\dfrac{4}{27}\cdot\dfrac{9}{2}=\dfrac{2}{3}\\\\\dfrac{8}{81}:\dfrac{4}{27}=\dfrac{8}{81}\cdot\dfrac{27}{4}=\dfrac{2}{3}\\\\\dfrac{16}{243}:\dfrac{8}{81}=\dfrac{16}{243}\cdot\dfrac{81}{8}=\dfrac{2}{3}

A manufacturer makes plastic wrap used in food packaging and aims to have a minimum breaking strength of 0.5 kg. If the mean bre
Darina [25.2K]

Answer:

Option D

Step-by-step explanation:

A type I error occurs when you reject the null hypothesis when it is actually true.

The null hypothesis in this case is minimum breaking strength is less than or equal to 0.5.

A type one error would be allowing the production process to continue when the true breaking strength is below specifications.

Write the follow equation y=3x+2,in point-slope form?
vredina [299]

Answer:

Point-slope form :

y - 2 = 3(x - 0)

Step-by-step explanation:

We have given an equation:  y = 3x + 2

we need to write this equation in point-slope form

i.e y - y₁ = m(x - x₁)  , this is general form of point-slope form.

Now,

We can rewrite the given equation in point -slope form:

y = 3x + 2

or y - 2 = 3x

or y - 2 = 3(x - 0)  , This is the point-slope form.

here y₁ = 2 and x₁=0
