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.

12, 17, 22... find the 35th term

Answers

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
