Jared is going to plant 20 small plants around the edge of a circular garden that is 8 feet in diameter. If he spaces the plants
Hatshy [7]

Answer:

The space between the plants is approximately 1.26ft

Step-by-step explanation:

Given

Circular Garden

Number of plants = 20

Diameter of garden = 8ft

First, the circumference of the garden needs to be calculated; This is so because the plants that will be placed at the edge of the garden will occupy the circumference of the circle.

Calculating the circumference....

Circumference = 2πr

Where r = radius

r = ½ * diameter.

r = ½ * 8ft

r = 4ft

So,

Circumference = 2π * 4

Circumference = 8π ft

Given that the plants will be spaced evenly.

The distance between them = Circumference ÷ Number of plants

Distance = 8π/20

Distance = 0.4π ft.

Solving further to get actual distance (take π as 22/7)

Distance = 0.4 * 22/7

Distance = 8.8/7

Distance = 1.2571428571 ft

Distance = 1.26ft (Approximated)

Hence, the space between the plants is approximately 1.26ft

The reading speed of second grade students in a large city is approximately normal, with a mean of 90 words per
kari74 [83]

Answer:

The probability that a random sample of 10 second grade students from     the city results in a mean  reading rate of more than 96 words per minute

P(x⁻>96) =0.0359

Step-by-step explanation:

<em>Explanation</em>:-

<em>Given sample size 'n' =10</em>

<em>mean of the Population = 90 words per minute</em>

<em>standard deviation of the Population =10 wpm </em>

<em>we will use formula</em>

<em>                            </em>Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }<em></em>

<em>Let X⁻  = 96</em>

                           Z = \frac{96-90 }{\frac{10}{\sqrt{10} } }

                          Z =  1.898

<em>The probability that a random sample of 10 second grade students from     the city results in a mean  reading rate of more than 96 words per minute</em>

<em></em>P(X^{-}>x^{-} ) = P(Z > z^{-} )<em></em>

<em>                    = 1- P( Z ≤z⁻)</em>

<em>                    = 1- P(Z<1.898)</em>

                   = 1-(0.5 +A(1.898)

                   = 0.5 - A(1.898)

                   = 0.5 -0.4641 (From Normal table)

                  = 0.0359

<u><em>Final answer</em></u>:-

The probability that a random sample of 10 second grade students from  

                = 0.0359

Help plz<br> I don't understand
IrinaVladis [17]

Answer:

(-9,-3.4)

Step-by-step explanation:

By adding 2.1x and subtracting 5.3 from the top equation, it will end up as 2.1x=4y-5.3

By adding 5.5y to the bottom equation, it will end up as 2.1x=5.5y-0.2.

By the equal valuesmethod, they are equal: 5.5y-0.2=4y-5.3

5.5y+5.1=4y

5.1=-1.5y

y=-3.4; this gets us our y-coordinate.

To get the x-coordinate, you plug the value for y back into the original equation.

-2.1x-4y=5.3

-2.1x-4(-3.4)=5.3

-2.1x-13.6=5.3

-2.1x=18.9

x=-9
