Answers
Answer:
5.5
Step-by-step explanation:
The first 10 natural numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10. Mean = Sum of Observations/Total No of Observations. Mean = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 ÷ 10. Mean = 55/10. Mean = 5.5.
mode is 5 occuring 3 times
Ratio of 100 and 10
= 10/100
=10:1
4. Find
the measure of the third angle if
two angles are
40,80
answer-60
Find the complementary and Supplementary
60
To find the angle which is supplementary to another angle, subtract the given angle from 180 degrees. For example, if one angle is 60 degrees, then another angle is 180 – 60 = 120 degrees.
same for complemantry 90-60 is 30
| 40% of a number is 800 then find the
number ?
Let the number be x. ⇒40100 × x = 800⇒25 × x = 800⇒2 × x = 5×800⇒2x = 4000⇒x = 40002⇒x = 2000.
I hope this helps u
pls mark me as brianliest
