Answer:
The blue liquid is toxic
Step-by-step explanation:
From the calculations I have done and attached to this problem
Null hypothesis:
H0 : p1 <= p2
Alternate hypothesis:
H1 : p1 > p2
^p1 = 0.925
^p2 = 0.2250
^P = (x1 + x2)/(n1+n2)
= 0.575
After calculating, I got test statistics = 6.33 ( check attachment)
P(z > 6.33) = 0.0000
In conclusion, our pvalue has been found to be less than the level of significance 0.05 so we reject null hypothesis and accept that we have enough sample evidence that the blue liquid is more toxic in comparison to white one.
Please check attachment for calculated test statistics.
Step-by-step explanation:
L ----------V-------------U
LV = VU
UV = 6-3x
LU = 14x + 2 = 2UV
14X +2 = 12 - 6X
20X = 10
X = 0.5
UV = 6 - 3(0.5)
= 4.5
LU = 9
Answer:
When the slope is UNDEFINED, that means the denominator of the slope formula is ZERO .
Slope formula = (y2 - y1)/(x2 - x1), and the graph is a VERTICAL line and the equation of the line is x =7 . Point (7, -4) is a point on the line.
Hope this helps...
