Answer:
No, because z-statistics lies within the critical region.
Step-by-step explanation:
The z value is calculated to determine whether the null hypothesis should be accepted or rejected. The null hypothesis is rejected when the z-value lies outside the critical region. The critical region is determined by the sample data.
Answer:
a) 20
Step-by-step explanation:
Use similar triangles.
2/3 = x/30
3x = 2 * 30
3x = 60
x = 20
Answer: a) 20
Answer:
7. y = x + 4
8. y = -3x - 2
Step-by-step explanation:
7. m = 1 , b = 4
y = mx + b will be y = x + 4
8. (1,-5) and (-3,7)
Slope (m) = 7 - (-5) / -3 - 1
= 7 + 5 / -4
= 12 / -4
= -3
y = mx + b will be y = -3x -2
Answer:
4(2x-3y+8)
Step-by-step explanation:
8x-12y+32
4(2x-3y+8)
i dont know this one sorry
