Answer:
2.4
Step-by-step explanation:
To find the mean absolute deviation, find how much each value is away from the mean, and divide it by the number of numbers you have. In this case, the mean is 5, and the deviation of each number is 4, 2, 0, 2, and 4. Add these up and you get 12. Divide 12 by the number of numbers which you have, which is 5, to get 2.4.
We have that The mean absolute deviation of the set of data. 2, 3, 5, 7, 9 is
[tex]\sigma=2.24[/tex]
From the question we are told
Find the mean absolute deviation of the set of data. 2, 3, 5, 7, 9
Generally the equation for the mean absolute deviation is mathematically given as
[tex]\sigma={\frac{\sum(x-u)}{N}[/tex]
Where
[tex]x=\frac{2+3+5+7+9}{5}\\\\x=5.2[/tex]
Therefore
[tex]\sigma={\frac{\sum(x-u)}{N}\\\\\sigma=\frac{3.2+2.2+0.2+1.8+3.8}{5}\\\\\sigma=2.24[/tex]
Therefore
The mean absolute deviation of the set of data. 2, 3, 5, 7, 9 is
[tex]\sigma=2.24[/tex]

The diameter of the Sun is 1.4 x 10⁶ km. The diameter of the planet mars is about 7000km. What is the approximate ratio of the diameter of the Sun to the diameter of Mars?
Answer:
200 : 1
Step-by-step explanation:
Given that,
The diameter of the Sun is 1.4 x 10⁶ km and the diameter of the planet mars is 7000 km.
We need to find the ratio of the diameter of the Sun to the diameter of Mars. Let the ratio is R. So,
[tex]R=\dfrac{\text{diameter of the Sun}}{\text{diameter of Mars}}\\\\R=\dfrac{1.4\times 10^6\ km}{7000\ km}\\\\R=\dfrac{200}{1}[/tex]
Hence, the ratio is 200:1.

Explain the difference between the associative addition and the commutative addition
Answer:
Associative states you can regroup numbers and you will get the same answer and the commutative property states that you can move numbers around and still have the same answer.
Example:
Commutative a+b=b+a
Associative a+ (b+c) = (a+b) +c= a+b+c

The perimeter of a rectangular window is 104 ft. The length is three times the width. Write a equation and solve for the width.
Answer:
L2 + W2 = P
L = 3W
2(3W) + 2W = 104
6W + 2W = 104
8W = 104
W = 13
Step-by-step explanation:
perimeter is 2 times length plus two times width.
add these togethter to get 104 (the given number)
then create an equation to find length based on the given number
simplify and find w.
Answer: width = 13 ft
Step-by-step explanation:
Perimeter (P) = 2 × Length (L) + 2 × width (w)
Given: P = 104, L = 3w
P = 2L + 2w
104 = 2(3w) + 2w
104 = 6w + 2w
104 = 8w
13 = w

Which value would make the statement true? StartFraction 2 Over question mark EndFraction greater-than StartFraction 4 Over 12 EndFraction 4 6 12 24
Answer:
4
Step-by-step explanation:
Given the expression 2/? > 4/12, to find the value of ? that will make the expression true, we will cross multiply first
On cross multiplying:
2×12 > 4 × ?
24 > 4 × ?
Divide both sides by 4
24/4 > 4×?/4
6 > ?
This means that ? < 6
The answer will be a value that is less than 6. According to the option, the only value less than 6 is 4. Hence the correct answer is 4.

The power generated by an electrical circuit (in watts) as a function of its current c cc (in amperes) is modeled by P ( x ) = − 15 x ( x − 8 ) P(x)=−15x(x−8) What is the maximum power possible?
The maximum power is 4A.
What is Function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
The given function
P(x) = - 15x (x-8)
P(x) = - 15x² + 120x
The standard form of a quadratic function is:
y = ax² + bx + c
For which x is the maximum of the parabola
x = - b/2a
So, a = -15 and b = 120.
Then, x = - 120/(2 · (-15))
x = - 120/ (-30)
x = 4A

What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
Here, we have,
Since we are not told what to look for, we can as well look for the value of x, m∠SQT and m∠RQS
Given
m∠RQS=(4x-20)°
m∠SQT=(3x+14)°
m∠RQT=155°
The addition postulate is true
m∠RQT= m∠RQS + m∠SQT
Substitute the given parameters into the formula
155 = 4x-20+3x+14
155 = 7x-6
7x = 155+6
7x = 161
x = 161/7
x = 23
Solve for m∠RQS
m∠RQS = 4x-20
m∠RQS = 4(23)-20
m∠RQS = 92-20
m∠RQS = 72°
Solve for m∠SQT
m∠SQT = 3x+14
m∠SQT = 3(23)+14
m∠SQT = 69+14
m∠SQT = 83°
Hence, The solution is: the value of x, and the angles m∠SQT and m∠RQS are: x = 23, m∠RQS = 72°, m∠SQT = 83°.

Answer:
V varies 1/P.
V=K/P.
K=VP.
K=240×30.
=7200.
Therefore 7200=VP.
so.....
7200=120P.
P=7200/120.
P=60kg/cm^2.

Complete question :
A statistics professor wants to know the average GPA of the students enrolled in their class. They look up information on Canvas about the students enrolled in the class and compute the average GPA as 3.29
a. State whether the following statement is true or false. The population is all students enrolled in the accounting class.
b. Does the value 3.29 represent the population parameter or the sample statistic?
Answer:
True ; population parameter
Step-by-step explanation: The population comprises of all sets or participants relating to a study or experiment. For example, a population of male adults in the United States refers to the entire pool of adult population in the country. Hence, in the scenario above, the population refers to the entire student in the accounting class since the accounting class represents the entire pool of students.
B.) population parameter
Statistical estimates derived from a population is called the a parameter, since 3.29 represent the average score of the entire class.
Same statistic represents estimates derived from a sample (subset of the entire population).

What is the answer for -4-(7t-4)^2=-49
t₁ = (3√5 + 4)/7
t₂ = -(3√5 - 4)/7
Step-by-step explanation:- 4 - (7t - 4)² = - 49
- (7t - 4)² = - 49 + 4
- (7t - 4) = - 45 | (-)
(7t - 4)² = 45
(7t - 4)² = 3√5
7t - 4 = ± 3√5
7t - 4 = 3√5 => 7t = 3√5 + 4 => t₁ = (3√5 + 4)/7 7t - 4 = - 3√5 => 7t = - 3√5 + 4 => t₂ = -(3√5 - 4)/7When registering their cars, owners must identify the color that covers the largest portion of the vehicle.

In this region, are the events "silver" and "black" mutually exclusive? Find the probability that a randomly selected car from this region is mainly silver OR mainly black.
Answer:
0.41 probability
Step-by-step explanation:
0.22 + 0.19 = 0.41
Answer:Yes they are mutually exclusive!

Which number sentence states that x is at most 50?
A. x < 50
B. x < 50
C. x = 50
D.x > 50
E. x > 50
idk this one is kind of confusing me
Answer:
its A & B, x<50
Step-by-step explanation:
atmost means till 50.
atleast means more than 50.
The number sentence that states that x is at most 50 is option B: x ≤ 50.
In mathematical notation, the symbol "≤" means "less than or equal to." So, x ≤ 50 translates to "x is less than or equal to 50."
This means that x can be any value that is less than 50 or exactly 50.
Option A (x < 50) would mean "x is less than 50," excluding the value 50 itself.
Option C (x = 50) would mean "x is equal to 50," but it doesn't include any values less than 50.
Option D (x > 50) would mean "x is greater than 50," excluding the value 50 itself.
Option E (x ≥ 50) would mean "x is greater than or equal to 50," which includes values greater than 50, but it doesn't allow any values less than 50.
So, the correct choice to state that x is at most 50 (including the value 50) is option B: x ≤ 50.
