Answer 76
Step-by-step explanation:
Find the measure of the indicated arc in circle O. Use pic for more
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.

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.
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

12, 17, 22... find the 35th term
Answer:
a₃₅ = 182
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 17 - 12 = 22 - 17 = 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 5 , then
a₃₅ = 12 + (34 × 5) = 12 + 170 = 182

2. Write two numbers that are opposites and each more than 6 units away from 0.
Answer:
-7, 7
Step-by-step explanation:
Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it. (8, -8)
