Very easy:
Find volume by formula: W*H*L
6*5*4=120
10*10*2=200
120+200=320 cubic inches for first question
Answer:
does it say like x=_
Step-by-step explanation:
1 hour 15 minutes is the correct answer
Answer:
13.36
Step-by-step explanation:
I will first create a table
X. Y. XY. X²
1. 20. 20. 1
2. 24. 48. 4
3. 35. 105. 9
4. 46. 184. 16
5. 67. 335. 25
6. 80. 480. 36
1. 12. 12. 1
2. 34. 68. 4
3. 34. 102. 9
5. 78. 430. 25
ΣX = 32
ΣY = 430
ΣXY = 1744
ΣX² = 130
n = 10
The formula for regression line is given as :
Y = a + bX
a = intercept
b = slope
The question requires us to find b which is the slope.
b = nΣXY-ΣXΣY/nΣX²-(ΣX)²
= 10x1744-32x430/10x130-(32)²
= 17440-13760/1300-1024
= 3680/276
= 13.36
b = 13.36
Answer:
1st option
Step-by-step explanation:
For any input of value <em>x</em>, the output <em>y </em>is always 2. The equation would then be y = 2, which would have 0 slope.
