The marks of 10 pupils in jhs three are 88,80,75,70,38,45,70,60,60,50. Find the a. Arithmetic mean mark
b. Modal mark
c. Third quartile
Answers
First add all the values together (88+80+75+70+38+45+70+60+60+50) and divide them by the number of values (10). Which would equal to 63.6
b) Modal Mark
This is the mode of the values (the value that appears most often in the set of data values) which would be 70 and 60

Using base conversion method, 2FA.C8 base 16 can be expressed as:
1372.628 in octal11022.3423120034 in pental1011111010.11001 in binaryWhat is 2FA.C8 base 16 expressed in Octal form?To express 2FA.C8 in octal form, it is first converted to a decimal form as follows:
where:
F = 15
A = 10
C = 12
2FA.C8 = 2 × 16^2 + F × 16^1 + A × 16^0 + C × 16^-1 + 8 × 16^-2
2FA.C8 = 762.7812510 in decimal.
Then, convert 762.7812510 to octal as follows:
First the integral part is converted to octal by repeated division by 8.The fractional part is converted to octal by repeated multiplication by 8 until we get to zero (here, we calculate up to ten digits)add the integral and fractional part together762 / 8 = 95 remainder 2
95 / 8 = 11 remainder 7
11 / 8 = 1 remainder 3
1 / 8 = 0 remainder 1
762 = 1372
Then;
0.78125 × 8 = 6 + 0.25
0.25 × 8 = 2 + 0
0.78125 = 0.62
Therefore, 762.78125 in decimal = 1372.628 in octal
What is 2FA.C8 base 16 expressed in pental form?To convert 2FA.C8 base 16 to pental form, we use its value in decimal for conversion.

the number of kilo gram of water in human body varies directly as the mass of the body. A 96kg person contains 64kg of water. how many kilo gram of water are in a 60kg person? (show your solution)
Answers
Body weight = k x Water content
k = constant of proportionality
96 = k 64
k = 96/64
k = 1.5
Body weight = 1.5 Water content
60 = 1.5 Water content
Water content = 60/1.5
Water content = 40 kg.

An electron on an energy level has an energy of 16.32 x 10−19 J. It moves to another level by releasing 5.4 x 10−19 J of energy. Which of the following descriptions mostly likely explains what occurred?
The electron moved down to an energy level and has an energy of 10.92 x 10−19 J.
The electron moved down to an energy level and has an energy of 21.72 x 10−19 J.
The electron moved up to an energy level and has an energy of 10.92 x 10−19 J.
The electron moved up to an energy level and has an energy of 21.72 x 10−19 J.
Answers
Answer:
The electron moved down to an energy level and has an energy of
[tex]10.92 \times 10^{-19} \textsf{J}[/tex]
Step-by-step explanation:
[tex]\textsf{initial energy level of electron}= 16.32 \times 10^{-19} \textsf{J}[/tex]
[tex]\triangle E =\textsf{energy released}= 5.4 \times 10^{-19} \textsf{J}[/tex]
A positive energy change means that the electron absorbs energy, while a negative energy change implies a release of energy from the electron.
Therefore, when an electron absorbs energy, the electron moves up to higher energy levels, and when an electron releases energy, it moves to lower energy levels.
[tex]\triangle E=E_2-E_1[/tex]
[tex]\implies 5.4 \times 10^{-19} = 16.32 \times 10^{-19} -E_1[/tex]
[tex]\implies E_1= 16.32 \times 10^{-19} -5.4 \times 10^{-19}[/tex]

Answers
Answer:
x = -21/23 or 0.913 (rounded to the nearest thousandth)
Step-by-step explanation:
Step 1: Add 2/5 to both sides
1. -1/5x - 2/5 + 2/5 = 4/3x + 1 + 2/5
2. -1/5x = 7/5 + 4/3x
Step 2: Subtract 4/3x from both sides
1. -1/5x - 4/3x = 7/5 + 4/3x - 4/4x
2. -23/15x = 7/5
Step 3: Multiply both sides by 15
1. (15)-23/15x = 7/5(15)
2. -23x = 21
Step 4: Divide both sides by -23
1. -23x/-23 = 21/-23
2. x = -21/23 or 0.913 (rounded to the nearest thousandth)
