Answer:
0.2
Step-by-step explanation:
Given the data :
Day : Mon Tue Wed Thu Fri Sat Sun
# of sick days 22 11 16 17 21 28 25
The expected count of sick days taken on Saturday is obtained thus :
Expected count = (row total * column total) / overall total
Here, the table is just one way :
Hence, we use :
Observed value / total days
Hence,
Expected count on Saturday = sick days on Saturday / total sick days
Expected count on Saturday = 28 / (22+11+16+17+21+28+25)
Expected count on Saturday = 28 / 140
= 0.2

Assign variables :
Let x = first consecutive even
Let x + 2 = second consecutive even
Let x + 4 = third consecutive even
4x = 6 + 2(x+4)
4x = 6 + 2x + 8
4x = 2x + 14
4x - 2x = 14
so your answer is 7,9and 11</span>

Answer:
1.2 sq in.
Step-by-step explanation:
We know the formula to find the area of a trapezoid is a+b/2(h)
4+8/2(5)=12/10
12/10=1.2
Therefore the area is 1.2 sq in.
Answer:
3n + 8 = 44
Subtract both sides by 8.
3n = 36
Divide both sides by 3.
n = 12.
