Answer:
95
Step-by-step explanation:
let x be his mark in the fourth test, then
mean = 
= 83 ( multiply both sides by 4 )
83 + 81 + 73 + x = 332
237 + x = 332 ( subtract 237 from both sides )
x = 95
Answer:
6
Step-by-step explanation:
Let the 4 people be A, B, C and D. If each of them shakes hands with another person exactly one time then that means
A shakes with B, C and D. So 3 handshakes
B already shakes with A. So B shakes with C and D. 2 handshakes
C already shakes with A and B. So C shakes with D only. 1 handshake.
D already shake hand with all above.
Total handshakes: 3 + 2 + 1 = 6
Answer:
Greatest to least is 0.836 , 0.683, 0.386 , 0.3.
Step-by-step explanation:
Given : 0.386; 0.3; 0.683; 0.836.
To find : which Is greatest to least.
Solution :" We have given 0.386; 0.3; 0.683; 0.836.
In 0.386
Tenth place is 3 and hundredth place is 8
In 0.3
Tenth place is 3 and hundredth place 0
In 0.683
Tenth place is 6 and hundredth place 8
In 0.836.
Tenth place is 8 and hundredth place 3.
So, Greatest number is 0.836 ,
Least number is 0.3.
Therefore, Greatest to least is 0.836 , 0.683, 0.386 , 0.3.
