Answer:
185.68 cm3
Step-by-step explanation:
SA = 2 (L x W) + 2 (L x H) + 2 (W x H)
= 2 (8.2 x 3.4) + 2 (8.2 x 5.6) + 2 (3.4 x 5.6)
= 2 (27.88) + 2 (45.92) + 2 (19.04)
= 55.76 + 91.84 + 38.08
SA = 185.68 cm3
Answer:
1. t > -6 (Graph A)
2. x ≤ −80 (Graph B)
3. b < 13 (Graph C)
Step-by-step explanation:
<u>1. t < 5t + 24</u>
t − 5t < 5t + 24 − 5t
−4t < 24
−4t/−4 < 24/−4
t > −6
<u>2. 5x−9≤4.1x−81</u>
5x - 9 - 4.1x ≤ 4.1x - 81 - 4.1x
0/9x - 9 ≤ -81
0.9x - 9 +9 ≤ -81 + 9
0.9x ≤ -72
0.9/0.9 ≤ -72/-72
x ≤ -80
<u>3. 4b+4(1-b)>b-9</u>
so so and on
Answer:
As in explanation.
Step-by-step explanation:
A) SSE means "Error Sum of Squares". The source of it is the sum of squared deviations within groups.
B) SSTR means "Treatment Sum of Squares". It's source is the weighted sum of squared deviations of group means from grand mean. It's the sum of squares between groups.
C) SST means "Total Sum of Squares''. It's source is total sum of squared deviations from the grand mean. It is a sum of SSE and SSTR.
Making an equation,
Let heralds age be x
10+6x=4x+40
Seperating constants and variables,
6x-4x=40-10
2x=30
x=30/2
=15
Heralds age is 15,
Substitute x with 15 in the equation for rechecking
