Let x be the first digit.
Let y be the second digit.
Let z be the third digit.
x+y+z=18
y= (-2)(-4)
y= 8
x= 3^2
x= 9
Therefore z=1.
The number is
= 100x+10y+z
= 100(9)+10(8)+(1)
= 981
Answer:
Step-by-step explanation:
since the data is already arranged in ascending to descending u don't have to change.
upper quartile (Q3) = 3(n + 1)/4 (n means no of data)
=3(10 + 1)/4
=3*11/4
=33/4
=8.25
=8 th term + 0.25(9 th term - 8 th term)
=11 + 0.25(13 - 11)
=11 + 0.25*2
=11 + 0.5
=11.5

3. Then:


Answer:
71, 72, 73, 74 . for details, check below
Step-by-step explanation:
a) Let's assume that among the four consecutive numbers, the first one is x,
so, the four consecutive numbers should be:
- x
- x+1
- x+2
- x+3.
According to the question,
(x) + (x + 1) + (x + 2) + (x + 3) = 290
<h2>
b)</h2>
(x) + (x + 1) + (x + 2) + (x + 3) = 290
4x + 6 = 290
4x = 284
x = 284÷ 4
x = 71.
So, the numbers are,
71, 72, 73, 74
