Answer:
78Explanation:
acb − (a + d)
a = -2b = 3c = -12d = -4= (-2) (-12) (3) - (-2 + -4)
Parenthesis: (-2 + -4) = -6
= (-2) (-12) (3) - (-6)
Simplify (-2) (-12) (3): 72
72 - (-6)
78if a=−2 , b=3 , c=−12 , and d=−4 for expression acb−(a+d) then its value is 78.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is acb−(a+d)
a times c times b minus a plus d
The values of a, b, c and d are given.
In the given expression a,b,c and d are variables and plus and minus are operators
a=−2 , b=3 , c=−12 , and d=−4 .
Substitute these values in expression acb−(a+d)
(-2)(-12)(3)-(-2+(-4))
When minus is multiplied two times we get positive, if three times we get negative
72-(-2-4)
72-(-6)
Seventy two plus six
72+6
Seventy eight
78
Hence if a=−2 , b=3 , c=−12 , and d=−4 for expression acb−(a+d) then its value is 78.

Step-by-step explanation:
Three shipping companies want to compare the mean numbers of deliveries their drivers complete in a day.
The first two shipping companies provided their data from a sample of drivers in a table.
Company C showed its data in a dot plot.
Answer the questions to compare the mean number of deliveries for the three companies.
1. How many drivers did company C use in its sample?
Write your answer in the space below.
2. What is the MAD for company C's data? Show your work.
Write your answer in the space below.
3. Which company had the greatest mean number of deliveries?
Write your answer in the space below.
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Write your answer in the space below.
Answer:
Step-by-step explanation:
1. the company C used 10 drivers
2. 6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10
(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)
4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4 = 16/10 = 1 6/10
3. The groups that had the most deliveries where group A and B
4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4
By reading the dot plot,
Number of drivers used by company C in its sample = 10
Mean absolute deviation for company C's data = 2
Company B has the greatest mean number of deliveries.
The mean deliveries of company B is 4 times MAD of company A.
What is dot plot?Dot plot is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis.
Number of units used in the sample of a dot plot can be calculated by simple counting.
What is mean absolute deviation?The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.
We are given the sum of each point from the mean. It is 20. Mean absolute deviation can be calculated by dividing this sum by number of observations.
Mean absolute deviation of company C = 20/10 = 2.
Mean A = 6
Mean B = 14
Mean B - Mean A = 8 = 4 * 2 = 4 times MAD (since MAD =2 for both companies).

Plsss can someone answer I have 2 minutes
Answer:
x = 2
Step-by-step explanation:
You can make a ratio out of this!
2 / x = (x+1) / 3
1. Cross multiply^
2. 2 * 3 = x (x+1)
3. 6 = x^2 + x
3. x^2 + x - 6
4. Factor^
5. (x-2)(x+3)
6. x - 2 = 0 turns into x = 2
7. x + 3 = 0 turns into x = -3
8. There's not way to measure -3 yet, so you are left with x = 2
gonzalo nacio el 18 de sptiembre de 1945 si bertha nacio cuatro decadas y un lustro cual es la fecha de nacimiento de bertha
Answer: Bertha nació el 18 de septiembre de 1990.
Step-by-step explanation:
Gonzalo nació el 18 de septiembre de 1945.
Bertha nació cuatro décadas y un lustro después.
Una década son 10 años
Un lustro son 5 años
Entonces 4 décadas y un lustro son:
4*10 años + 5 años = 45 años
Esto significa que Bertha nació 45 años después que Gonzalo.
Entonces si Gonzalo nació en 1945, Bertha nació en el año:
1945 + 45 = 1990
Bertha nació el 18 de septiembre de 1990.
La fecha de nacimiento de Bertha es el 18 de septiembre de 1990.
How many years does a decade have?A decade is composed of 10 years. So, if there are 'x' decades, then that means there are going to be [tex]10 \times x[/tex] years in it.
For this case, we are given that:
Date of birth of Gonzelo is 18th of Sept. 1945
Bertha born after 4 decades and 5 years of Gonzelo's birth.
4 decades = 4 times 10 = 40 years
Thus, 4 decades + 5 years = 40 + 5 = 45 years.
45 years after 1945 uis 1945 + 45 = 1990
Thus, date of birth of Bertha is 18th Sept. 1990

Find the missing value to complete the square.
x^2 + 8x + __ = 0
Answer:
−x^2 − 8x
Step-by-step explanation:
Lets say y is the missing value
Add -x^2 to both sides.
x^2+8x+y+−x^2=0+−x^2
8x+y=−x^2
Add -8x to both sides.
8x + y + −8x = −x^2 + −8x
y = −x^2 − 8x
So the whole equation would be
x^2 + 8x + −x^2 − 8x = 0

Step-by-step explanation:
The expression 6e² represents the surface area of a cube where e represents the length of each edge. What is the surface area, in square centimeters, of a 5-centimeter cube?
The surface area of a cube is expressed as: 6e²
Where e = Length of each edge
The surface area, in square centimeters, of a 5-centimeter cube
e = 5cm
Therefore, the surface area of the cube = 6 × 5²
= 6 × 25
= 150 cm²
