Answer:
The answer is the second option. x = -5.873 , x = 1.873
Step-by-step explanation:
1. add 11 to both sides of the equation
x^2 + 4x = 11
2. find a value that is equal to the square of half of b
(b/2)^2 = (2)^2
3. add the term to each side of the equation
x^2 + 4x + (2)^2 = 11 + (2)^2
4. simplify the equation
x^2 + 4x + 4 = 15
5. factor the perfect trinomial square into
(x + 2)^2 • (x + 2)^2 = 15
6. solve the equation for x
x = 1.873 , x = -5.873

A warehouse worker loads a cart with 14 boxes. The boxes have an average weight of 24 pounds. The worker picks up a new box and puts it on the cart. Now the average weight of the boxes is 25 pounds. What is the weight of the new box? Round your answer to the nearest whole pound.
Answer: 39 pounds
Step-by-step explanation:
At first, the warehouse worker loads a cart with 14 boxes and the boxes have an average weight of 24 pounds. The total weight of the boxes will be:
= 14 × 24
= 336 pounds
Since the worker picks up a new box and puts it on the cart and the average weight of the boxes is 25 pounds. It means that the boxes are now 15 and their total weight will be:
= 15 × 25
= 375 pounds
The weight of the new box will be:
= 375 - 336
= 39 pounds

The area of a circle is 121π ft². What is the circumference, in feet?
Answer:
· Area = pi*r^2. 121 = pi*r^2. Solve for r. Circumference = 2*pi*r. plug r into that equation and solve for Circumference
Use the given functions to set up and simplify f e e t . 121 π f t 2 = f e e t = f e 2 t
Step-by-step explanation:
The circumference of the given circle will be 22π feet.
What is circumference?Circumference refers to the distance around the edge of a circle or any other curved shape. It is essentially the perimeter of the circle, and it is calculated by multiplying the diameter of the circle by the mathematical constant pi (π).
The area of a circle is given by the formula:
A = πr²
where "r" is the radius of the circle. We are given that the area of the circle is 121π ft². Therefore, we can write:
121π = πr²
Dividing both sides of the equation by π, we get:
121 = r²
Taking the square root of both sides of the equation, we get:
r = 11
Therefore, the radius of the circle is 11 feet.
The circumference of a circle is given by the formula:
C = 2πr
Substituting the value of "r" that we found above, we get:
C = 2π(11) = 22π
The circumference is 22π feet.

e) What does the value of the mean absolute deviation tell you about the spread of the data? (2 points)
Answer:
The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset. ... Step 2: Calculate how far away each data point is from the mean using positive distances.
Mean deviation is defined as how much is each element of the data is far away from the mean of the data.
What is mean in statistics?We can define the mean of the given data set as the average of all the numbers. Mathematically, we can write mean as -
M = ∑x{i}/n
Given is to discuss what does the value of mean absolute deviation tell about the spread of the data.
Mean deviation is defined as how much is each element of the data is far away from the mean of the data. Mathematically, we can write mean deviation as -
[tex]$\frac {1}{n} \sum \limits_{i=1}^n |x_i-m(X)|[/tex]
where -
m(X) = average or mean value(n) = number of data elements in the data setx(i) = data valuesTherefore, Mean deviation is defined as how much is each element of the data is far away from the mean of the data.
