Answer:
The mean of tree heights at Yard Works is 8 feet. The mean of tree heights at The Grow Station is 9 feet. The mean absolute deviations of the tree heights at both yards is 2.
Answer:
The heights, in feet, of the trees for sale at two nurseries are shown below.
Yard Works: 7, 9, 7, 12, 5
The Grow Station: 9, 11, 6, 12, 7
Which statements are true regarding the measures of center and variability of these data sets? Select three choices.
________________________________________________________
1 The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
2 The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.
3 The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
4 The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
5 The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
Step-by-step explanation:
Yard works has...
mean=8
median=7
mode=7
range=11
because in order it is 5 7 7 9 12
(5+7+7+9+12)/5=8
5 7( 7 )9 12 is the median
and seven occurs the most
and with this logic...
THE GROWSTATION has a
mean=9
median=9
mode=n/a
range=6

Group of answer choices
LaTeX: A=325\left(1.07\right)^tA = 325 ( 1.07 ) t
LaTeX: A=325\left(0.93\right)^tA = 325 ( 0.93 ) t
LaTeX: A=325\left(0.07\right)^tA = 325 ( 0.07 ) t
LaTeX: A=325\left(1.7\right)^t
Answer:
A=325(1.07)^t
Step-by-step explanation:
I got an 100 on the test
[tex]A=325(1.07)^t[/tex]shows the exponential growth rate of 7%
What is a function?A relation is a function if it has only One y-value for each x-value.
The formula for exponential growth is given by:
[tex]A = P(1 + r)^t[/tex]
where A is the amount after t periods, P is the initial amount, and r is the rate of growth.
To represent a growth rate of 7%, we can use:
[tex]A = 325(1 + 0.07)^t[/tex]
Hence, [tex]A=325(1.07)^t[/tex] shows the exponential growth rate of 7%

Whats the measure of z
Answer:
z = 24°Step-by-step explanation:
Angle on a straight line= 180°90 + 66 + z = 180°156 + z = 180°z = 180° - 156°z = 24°let y be 2x
90 + 66 + 24 + X + 2x = 360° (angles at a point)
180° + 3x = 360°
3x = 360° - 180°
3x = 180°
divide both sides by 3
3x/3 = 180/3
X = 60
2x = 2(60) = 120°
therefore X = 60°
Y = 120°
90° + 66° + 24° + 60° + 120° = 360°
t the beginning of the season, MacDonald had to remove 555 orange trees from his farm. Each of the remaining trees produced 210210210 oranges for a total harvest of 417904179041790 oranges.
Write an equation to determine the initial number of orange trees (t)(t)left parenthesis, t, right parenthesis on MacDonald's farm.
Find the initial number of orange trees on MacDonald's farm.
orange trees
Answer:Initial number of trees (t)=204
Step-by-step explanation:
t = initial number of trees
Subtract 5 trees from the initial number of trees
we have,
t-5
each remaining tree made 210 oranges for a total of 41,790 oranges
We have,
(t-5) * 210=41790
Solve the equation
(t-5) * 210=41790
Open the bracket
210t-1050=41790
210t=41790+1050
210t=42840
Divide both sides by 210
210t/210=42840/210
t=204
The initial number of trees on MacDonald farm orange trees (t)=204
If 5 is removed from the initial trees
t-5=204-5
=199 trees
199 trees produce 210 oranges
We have,
199*210=41790 oranges
Alyssa is designing a cone to scoop water from a tank. She figured that the scoop should hold approximately 66 in3 of liquid. The diameter of her cone is 6.5 in. What should be the height of the cone? Round your answer to the nearest whole number. The height should be in
Answer:
11
Step-by-step explanation:
I divided 66 by 6.5 and got 10.153846153846153846153846153846 then I just rounded it to 11. I actually went based off of radius and height. Hope this helps:)
The height of the cone is 11.
Calculation of the height of the cone:Since She figured that the scoop should hold approximately 66 in3 of liquid. The diameter of her cone is 6.5 in.
So for determining the height we simply divided the 66 by the diameter
So,
[tex]= 66\div 6.5[/tex]
= 11
Therefore, we can conclude that The height of the cone is 11.

Solve for K
K-4a= -1
Answer:
I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
The value of K is given by the expression 4a - 1.
To solve for K in the equation K - 4a = -1, we want to isolate the variable K on one side of the equation. Here's the step-by-step process:
Start with the equation: K - 4a = -1.
To isolate K, we need to move the -4a term to the other side of the equation. We can do this by adding 4a to both sides of the equation:
K - 4a + 4a = -1 + 4a.
This simplifies to:
K = 4a - 1.
Therefore, the value of K is given by the expression 4a - 1.

Find the value of x to the nearest degree.
Answer: x = 58°
Step-by-step explanation:
Sine = opposite leg ÷ hypotenuse
We need to find the hypotenuse first with the Pythagorean theorem.
a² + b² = c²
5² + 8² = c²
25 + 64 = c²
89 = c²
√c² = √89
c = 9.43398
c ≈ 9.43
Sine = opposite leg ÷ hypotenuse
Opp. leg - 8
Hypotenuse - 9.43
To find this, you have to use the calculator
Make sure the calculator is on scientific
If your calculator is on your computer and in full screen, find 8 ÷ 9.43 and then click sin⁻¹, you should get 58.03334
If your calculator is on your computer in mini screen, find 8 ÷ 9.43. This time, click the arrow that looks smth like this: ↑
When you do that, you should be able to see sin⁻¹, so you click that and you'll also get 58.03334
58.03334 ≈ 58
x = 58°

2. The length of a rectangle is 5 feet more than the width. The perimeter of the rectangle is
58 feet.
Find the width of the rectangle.
The width of the rectangle is 12ft.
What is the difference between area and perimeter of a rectangle?The rectangle's perimeter is calculated using its length. Given by the total of the rectangle's sides, it is stated in linear units.
The space inside the rectangle is measured by area, on the other hand. It is measured in square units and equals the sum of the rectangle's length and width.
Let us suppose the width of the given rectangle be x
According to the given question;
Length of rectangle is 5ft more than its width
Therefore, length of rectangle= x+5
We know that,
Perimeter of rectangle = 2 ( length+breadth)
Perimeter of rectangle = 2[x+(x+5)]
It is given in the question that perimeter of the rectangle is 58ft
Thus,
⇒2( length+breadth) =58
⇒ 2[x+(x+5)] = 58
⇒ 2 (2x+5) = 58
⇒ 4x + 10 = 58
⇒ 4x = 58- 10 = 48
⇒ 4x = 48
⇒ x = 12
Thus, width of rectangle = 12 ft
length of rectangle = x+5 = 12+5 = 17ft
Hence, the width of the rectangle is 12ft.

8x−6y=1 what is the slope of the line
Answer:
m = 4/3
Step-by-step explanation:
Two ways to do this problem.
Method 1 change the Method 2 If a linear equation is in
equation to slope-intercept form standard form, ax =by = c then
8x - 6y = 1 the slope = -a/b
-6y = -8x + 1 In 8x - 6y = 1 a = 8 and b = -6
y = (-8x)/-6 +1/-6 So m = - (8)/-6 = 8/6 = 4/3
m = -8/-6= 4/3
Note: Method 2 only works if the equation is in standard form.
