Answer:
Associative Property
Step-by-step explanation:
- I would use the Associative Property because it states that you can add any numbers together no matter how they are separated or grouped (with parentheses).
- Knowing what we said in step 1, here are some other ways you can write the expression given (they are written in the steps below)
- 8 + 7 + 9
- (8 + 7) + 9
- (8 + 9) + 7
I hope this helps!
By definition, the volume of a rectangular prism is given by:
V1 = (w) * (l) * (h)
Where,
w: width
l: long
h: height
Substituting we have:
60 = (w) * (l) * (h)
if the length and the width double, and the height remains the same, we have:
V2 = (2w) * (2l) * (h)
Rewriting:
V2 = 4 * ((w) * (l) * (h))
V2 = 4 * V1
Substituting we have:
V2 = 4 * (60)
V2 = 240 cubic feet
Answer:
the new volume will be:
V2 = 240 cubic feet
Answer:
2
Step-by-step explanation:
Given the function
f(x) = x^3 − x + 4 in the interval [1,2]
We are to find the value of x for which f(x) = 7
Substitute f(x) = 7 into the expression as shown!
f(x) = x^3 − x + 4
7 = x^3 − x + 4
x^3 − x + 4 -7 = 0
x^3 − x - 3= 0
x^3 -x = 3
x(x²-1) = 3
x²-1 = 3 and x = 3
x² = 3+1
x² = 4
x = ±√4
x = ±2
Since x lies within the interval, [1,2] hence the value of x is 2
Answer: B - The IQR is the most resistant to extreme values.
Step-by-step explanation:
The Inter Quartile Range like the Range is used to measure the distance between data points in a data set. So the higher the IQR is, the further the data points are from each other. The reverse is true. It is calculated by subtracting the first quartile in the data set from the third quartile meaning that it represents the range between 50% of the data set.
The advantage of the IQR is that it is most resistant to outliers (extreme values) because it focuses on data points that are closer to the middle. This therefore gives a better reflection of the data set when there are outliers present.
For example, observe the following data set;
1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 200
Interquartile range = Q3 - Q1
= 17 - 5
= 12
Range = 200 - 1
= 19
Notice how IQR is more reflective of the data set.
Well i dont acutally kniw but what i can say is that the x = 20x and thats the most i can tell you sorry abiut that
