The mean height is 3.2 feet and thestandard deviation 0.6 feet. A… ... A forest ranger has data on the heights of a large growth ... mately what fraction of the trees should we expect to be.

The  fraction of the trees that is between 4.0 and 4.4 feet is 7%

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

x is the raw score, μ is mean and σ is standard deviation

Given that μ = 3.2, σ = 0.6, hence:

[tex]For\ x = 4:\\\\z=\frac{4-3.2}{0.6} =1.33\\\\\\For\ x = 4.4:\\\\z=\frac{4.4-3.2}{0.6} =2[/tex]

From the normal distribution table, P(4 < x < 4.4) = P(1.33 < z < 2) = P(z < 2) - P(z < 1.33) = 0.9772 - 0.9082 = 7%

The  fraction of the trees that is between 4.0 and 4.4 feet is 7%

Answer:

1x+ -4y= -16

Step-by-step explanation:

y= 1/4x + 4

subtract 1/4x from both sides

-1/4x + y= 4

multiply both sides by -4

1x -4y= -16

Answer:

One hosta = $ 12 , One shrub = $ 5

Step-by-step explanation:

Let;

x = hostas

y = shrubs

Emily spent $132 on 6 hostas and 12 shrubs.

6x + 12y = 132 ........................................ (i)

Chelsea spent $213 on 14 hostas and 9 shrubs

14x + 9y = 213 ........................................ (ii)

From (i)

12y = 132 - 6x

y = 11 - 0.5x  ........................................ (iii)

substitute (iii) into (ii)

14x + 9 (11 - 0.5x) = 213

14x + 99 - 4.5x = 213

9.5x = 114

x = $ 12

Substitute value of x in (iii)

y = 11 - 0.5(12)

y = 11 - 6 = $ 5

Answer:

A

Step-by-step explanation:

The expression for the width of rectangular placemats is (9x - 25) units.

Given that, the area of rectangular placemats=45x²-70x-150.

The area of a rectangle (A) is the product of its length 'a' and width or breadth 'b'. So, the area of the rectangle = (a × b) square units.

Now, 45x²-70x-150=(5x + 6)×b

⇒b=45x²-75x-150/(5x + 6)

⇒b=(5x + 6)(9x - 25)/(5x + 6)

⇒b=(9x - 25)

Therefore, the expression for the width of rectangular placemats is (9x - 25) units.

Answer:

14 - 13x

Step-by-step explanation:

take 13x + 1 away from 15

15 - (13x + 1) =  15 - 13x - 1  =  14 - 13x

The value of x is 1/2 and the measure of MG is 7.5 cm.

Given that, M is the midpoint of FG.

We need to find the measure of MG and FM.

In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.

Now, FG=MG+FM

⇒FG=MG+MG (MG=FM)

⇒FG=2MG

⇒15=2(13x+1)

⇒15=26x+2

⇒x=1/2

Now, MG=FM=13(1/2)+1=7.5 cm

Therefore, the value of x is 1/2 and the measure of MG is 7.5 cm.

Answer:

3x^2 + 5x + 4

Step-by-step explanation:

The expression for the height of the rectangle is found by dividing the expression for the area, 3x3 − x2 − 6x − 8, by the expression for the base, x − 2. Use synthetic division.

Step-by-step explanation:

AB = 72 so, then FB would be half of that

so 72 divided by 2 would be 36

5x+1=36 then do substitution

-1 from both sides (from +1 you gotta do the inverse)

5x = 35

divide 5 from both sides because in between 5 and x is a times so the inverse of that is divide

Answer: EG = 80

Step-by-step explanation: A parallelogram is a quadrilateral with opposite sides parallel to each other.

The diagonals of a parallelogram bisect each other, which means, using the figure as example:

EJ = JG

So, to determine EG, first find w:

[tex]4w+4=2w+22[/tex]

[tex]2w=18[/tex]

w = 9

Substituting:

[tex]EJ=4w+4[/tex]

[tex]EJ=4(9)+4[/tex]

EJ = 40

Since each segment has the same measure:

EG = 2EJ

EG = 2(40)

EG = 80

The measure of EG is 80 units

Answer:

The property used is Symmetric property of Equality.

Option B is correct option.

Step-by-step explanation:

We are given :

[tex]AR \cong TY\\[/tex]

Which property will give the step:

[tex]TY \cong AR\\[/tex]

Looking at the options:

We see that Symmetric property states that if a = b then b= a

Same is the case with the question.

We have :

[tex]AR \cong TY\\\\TY \cong AR\\[/tex]

If a = AR and b = TY

then the property is: a = b, b=a

So, the property used is Symmetric property of Equality.

Option B is correct option.

The answer is 20 meters.
