Answer:
The null hypothesis is rejected this means that 
The 95% confidence interval is 
Step-by-step explanation:
From the question we are told that
The standard deviation is s= 0.0001
The sample size is n = 25
The sample mean is 
The population mean is 
The null hypothesis is 
The alternative hypothesis is 
The test statistics is mathematically represented as
So the p-value from the z-table is mathematically represented as
seeing that
we reject the null hypothesis
The critical value of
obtained from the normal distribution table is
The margin of error is mathematically represented as
=> 
=> 
The 95% confidence level is mathematically represented as
=> 
=>
Answer:
Step-by-step explanation:
The negative out front only tells us which way the parabola will open. That means that the first one will open upside down, since it's got a negative out front. The value of the number that serves as the leading coefficient (the number stuck to the x-squared) determines how steep or wide-open the parabola's shape is. The leading coefficient in the first one is a 1, so it opens up exactly as wide as its parent graph does. The leading coefficient in the second one, a 2, means that the parabola will be skinnier or narrower than its parent. If the leading coefficient is greater than 1, the parabola will be narrower than its parent; if the leading coefficient is greater than 0 but less than 1, the parabola will open wider than its parent.
Hi Troppic20Pdge32,
-2(6 + s) ≥ -15 - 2s (All Real Numbers)
3s + 6 ≤ -5(s + 2) (s ≤ -2)
4/3s - 3 < s + 2/3 - 1/3s (s < 5 1/2)
Hope This Helps!
