The mean marks of 100 students were calculated as 65. At the time of checking it was found the marks 40 and 50 was wrongly copied and weeded out Find the correct mean marks.
Answers
Answer:
[ Because those two numbers are removed you need to reduce the number of terms to 98. ]
☆Solution☆
N=100
Mean=65
(Wrong Numbers=40,50)
Now,
Mean=Sum/No. of items
or,65=Sum/100
▪Sum=65×100=6500
After removing the unnecessary numbers,
New Sum=6500-40-50=6410
New no.of terms(N)=100-2=98
Now,
New Mean=New Sum/New N
=6410/98
=65.41

Find the measure of the indicated arc in circle O. Use pic for more
Answers
Note that m∡DC = 44°.
How did we arrive at this ?
Note that the measure of the central angle and the arc it creates are the same.
Thus, since ∠DOC creates ∡DC
Hence, ∡DC = 44°
Note that an inscribed angle in geometry is the angle created in the inside of a circle when two chords meet on the circle.
It may alternatively be defined as the angle formed by two given points on a circle at a specified position on the circle. one inscribed angle is formed by two circle chords that share one endpoint.

x ≈ 7.1
Step-by-step explanation:
The circumference of this circle is 2πx.
65/360 of that circumference is said to be 8
so we can solve x from
65/360 · 2πx = 8
which can be simlified to
2πx = 8 · 360/65
πx = 288/13
x = 288 / (13π) ≈ 7.1
Another company charges $8 per month and $0.03 per minute used. Which equation below best respresents the total cost for the month, c, for m miuntes used?
Answers
Answer: c = 8 + 0.03m
Step-by-step explanation:
From the question, we are informed that a company charges $8 per month and $0.03 per minute used.
The equation that best respresents the total cost for the month, c, for m miuntes used will be:
c = 8 + (0.03 × m)
c = 8 + (0.03m)
c = 8 + 0.03m
For example if 10 minutes was used, the cost will be:
c = 8 + 0.03m
c = 8 + (0.03 × 10)
c = 8 + 0.3
c = $8.3
