Chen says the product of 4x0 is the same as the sum of 4+0. Is Chen correct? Explain.
Answer:
No
Step-by-step explanation:
The product of zero and any number is zero. Basically, if you multiply any number with zero, you get zero. Hence, 4*0=0. However, anything added with zero is itself since you're basically not adding anything to that number. For example, nothing is being added to 4 in '4+0', so 4+0=4.
4*0=0
4+0=4

Compute 5DBE16-9AF416 using 2’s complement, leave your final answer in octal
5DBE16-9AF416 using 2’s complement is -2635716 octal.
We need to compute 5DBE16-9AF416 using 2’s complement, leave your final answer in octal.
What is two's complement?When two's supplement is utilized to address negative numbers, the main piece (MSB) is used to show the indication of the number. A 1 in the MSB position shows a negative number, and a 0 in the MSB position demonstrates a positive number. In two's supplement, negative numbers are addressed by the converse of the positive number in addition to 1.
To find the backwards of a number, every digit is just upset - 0 changes to 1, and 1 changes to 0. In this way, the converse of 5DBE16 is A2416. One is added to the opposite to find the two's supplements giving us A2417.
2's supplement of a number=the numbers supplement+1
5DBE16-9AF416=464416-9AF416=-54AF416+1=-54AF416
The two's supplement of a number can be determined by deducting the number from 2^n, where n is the number of pieces used to address the number. Along these lines, for this situation, we would take away 5DBE16 from 2^32, which gives us 464416.
Since the 2's complement of a number is equivalent to the negative, we can say that 5DBE16-9AF416=-54AF416.
To change over a two's supplement number to octal, we can involve a similar technique as we would use to switch a paired number over completely to the total. We bunch the pieces into three sets, beginning from the right, and convert each gathering into an octal digit.
In this way, the 2's supplements of 5DBE16-9AF416 would be composed as continues in octal 464416-9AF416=-2635716 octal
Therefore, 5DBE16-9AF416 using 2’s complement is -2635716 octal.

Which measure gives the most common rating?
O Mean
Median
O Mode
S
Answer:
a) Mean
b) Median
c) Mode
Step-by-step explanation:
a) The data set has no outliers, therefore taking the average (mean) would be the best.
b) The data has outliers which would skew a mean. None of the numbers repeat, therefore mode would not work, so by process of elimination, one can find that Median is the best.
c) This data set does not have numbers, therefore mean does not make sense. The most common rating would be the rating that occurs most often, which would be mode.
You start at (5, -2). You move up 2 units and left 10 units. Where do you end?
Based on the translation, your end position is (- 5, 0)

The percentage decrease is 43.75%
How to calculate the percentage?Initial volume = 3.2 millimeters
After experiment volume = 1.8 millimeters
Reduction = 3.2 - 1.8 = 1.4 millimeters
Therefore the percentage decrease will be:
= Reduction/Initial value × 100
= 1.4/3.2 × 100

20,000 ten thousands equals how many hundred thousands
20,000 ten thousand equals 2000 Hundred thousand.
As per the question statement, we are provided with a value: "20,000 ten thousand".
We are required to calculate how many hundred thousand are equal to 20,000 ten thousand.
To solve this question, let us first write down 20,000 ten thousand into the numerical format, i.e, [tex](20000*10,000)=200000000[/tex].
As we know, a hundred thousand when written down in the numerical format becomes 100,000, let us assume that 20,000 ten thousand equals to "x" number of Hundred thousand.
Therefore, we can form a linear equation in one variable "x" based on the condition, in the above-mentioned statement, which goes as [tex](100,000*x)=200000000[/tex]
[tex]or, (100,000x)=200000000\\or,x=\frac{200000000}{100,000}\\or,x=\frac{2*10^{8} }{10^5\\}or,x=(2*10^3)\\or,x=2000[/tex]
Hence, 20,000 ten thousands equals 2000 Hundred thousands.

I have been stuck on this for the past 10 mins PLS HELP
Answer:
55°
Step-by-step explanation:
m∠D = m∠A + m∠B since for a triangle, the exterior angle = sum of interior angles
We can rewrite this as
m∠A + m∠B = m∠D
Given m∠A = (2x)° , m∠B = (3x + 41)° and m∠D = 124° and substituting in the above equation,
2x + (x + 41.5) = 124
2x + x + 41.5 = 124
3x + 41.5 = 124
3x = 124 - 41.5 = 82.5
x = 82.5/3 = 27.5
But m∠A = (2x) = 2 x 27.5 = 55°
