The mean can be misleading if you don't know the spread of data items. True or false...
Answer:
True
Step-by-step explanation:
When data is skewed toward the high or low end, the mean can be a misleading measure of central tendency. In such a case the central tendency for the data items shifts toward either the high or low end -- away from the mean. The median then becomes the better measure.
The mean could be misleading when we don't know the spread of data items is to be considered as the true.
Role of mean:
The mean do have the high impact on the extreme observations. In the case when the observation is high so automatically the remaining observations should be low due to which the mean should be increased.
So based on this, we can conclude that The mean could be misleading when we don't know the spread of data items is to be considered as the true.

[tex]\left[\begin{array}{ccc}y=x&y=\frac{2}{3}x&y=\frac{2}{3}x +1 \\-6&-4&-3\\-3&-2&-1\\0&0&1\\3&2&3\\6&4&5\end{array}\right][/tex]
Step-by-step explanation:
-6: y = -6
y = [tex]\frac{2}{3}[/tex] (-6)
y = -4
y = [tex]\frac{2}{3}[/tex] (-6) + 1
y = -4 + 1
y = -3
-3: y = -3
y = [tex]\frac{2}{3}[/tex] (-3)
y = -2
y = [tex]\frac{2}{3}[/tex] (-3) + 1
y = -2 + 1
y = -1
0: y = 0
y = [tex]\frac{2}{3}[/tex] (0)
y = 0
y = [tex]\frac{2}{3}[/tex] (0) + 1
y = 1
3: y = 3
y = [tex]\frac{2}{3}[/tex] (3)
y = 2
y = [tex]\frac{2}{3}[/tex] (3) + 1
y = 2 + 1
y = 3
6: y = 6
y = [tex]\frac{2}{3}[/tex] (6)
y = 4
y = [tex]\frac{2}{3}[/tex] (6) + 1
y = 4 + 1

12x + 3y = 15 and 2x – 3y = 13.
Answer:
X=1 and Y=1 in the first question

simply 12X means 12*x, so x=1 and 12*1+3*1=15 question 1
and question 2
2X means 2*X x=8 so 2*8=16 so 16-3 because Y=1 and

Dani decides to add the cost of each shirt and the cost of each bag together, and then multiply by seven to find the total cost. Write an algebraic expression for the total cost of the gifts using Dani’s method. Remember, use t and b as your variables. (3 points)
Answer:
Total cost of 7 pair = 7(t + b)
Step-by-step explanation:
Given:
Cost of each shirt = t
Cost of each bag = b
Number of pair = 7

Hannah estimated that a bottle could hold 2.2 liters. The actual volume of the bottle was 2 litters. What was the percent error in hannas measurements?
Answer:
I dont have a direct answer but i think i can help.
Step-by-step explanation:
For example, 2%, read "percent", is two every hundred. When we have 100 liters of water, 2% is 2 liters. If we have 200 liters of water, then 2% is 4 liters. Converting a percentage into a fraction can be done by dividing by 100, following the definition of a percentage.
A store buys a piano from the vendor for $6000 then marks the price up 15% before they sell it to the public. What is the retail price of the piano?
Answer:
$6900

The scale factor of a model plane to the actual plane is 1 to 20.
Find the wing area of the model if the wing area of the actual plane is 400 ft^2
Answer:
1 ft²Step-by-step explanation:
The scale factor = 1 : 20
The area is the product of two dimensions, so the area of the model part to actual part is:
1 ² : 20 ² = 1 : 400If the actual plane has wing area of 400 ft², then the model will have wing area:
400 ft² / 400 = 1 ft²wich fraction is equivalent to 2/8
Answer:
1/4
Step-by-step explanation:
Simplified the answer would be: 1/4 - Once you divide 2 and 8 by GCF of 2

A student graphs 5x−y=7 on a coordinate plane. Which equation, when graphed on the same coordinate plane, will result in a system of equations with no solution? 5x−y=7 5 x − − y = 7 5x−y=1 5 x − − y = 1 x−5y=35 x − − 5 y = 35 x−5y=5
Answer:
5x−y=1
Step-by-step explanation:
An equation is a statement that shows the equality between two expressions.
An equation is said to have no solutions if after solving the equation and the result is a statement like a = b, where a and b are different numbers.
The equation after it is simplified would have the same coefficients and different constant.
Given:
5x−y=7
An equation that will result in a system of equations with no solution will have the same coefficient but different constant.
Hence 5x−y=1, would give a system of equations with no solution.
Simplifying gives:
7 = 1 (no solution)
