Answer:
Step-by-step explanation:
dy/dx=(y2-y1)/(x2-x1)
dy/dx=(-2-14)/(10-11)
dy/dx=-16/-1
dy/dx=16
Answer:
The first one: y - 2 = -5(x - 2)
Step-by-step explanation:
Answer:
112
Step-by-step explanation:
8 − 4 + 9 × 12
Using PEMDAS, we multiply first
8 − 4 + 108
Add and subtract from left to right
4+108
112
We are given
<span>μ > 1180
</span><span>α = 0.02
</span><span>σ = 201.71
x = </span><span>1198.79
n = 200
The null hypothesis is </span>μ ≤ 1180 while the alternative hypothesis is μ > 1180
The test statistic is 1.32 which means that the confidence internval is 98%. Getting the z-score
z = (x - μ) / σ
z = (1198.79 - 1180) / 201.71
z = 0.093
For a normally distributed population, the z-score of 0.093 has a p-value of
p = 0.46
