469.4/62=7.57
Step-by-step explanation:
its the correct answer
Answer:
m = 13
Step-by-step explanation:
Given
m - 5 = 8 ( isolate m by adding 5 to both sides of the equation )
m = 8 + 5 = 13
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
<span>2x + y = 4
y = -2x + 4
slope = -2 and y-intercept = 4

Answer:
She lost 475 points
Step-by-step explanation:
Given:
Lost point in next level = 75
Number of target = 5
Lost point in each target = 80
Find:
Total changes
Computation:
Total lost points = Lost point in next level + [Number of target][Lost point in each target]
Total lost points = 75 + [5][80]
Total lost points = 75 + 400
Total lost points = 475 point
