Answer:
B. Cs = 5 + 3s
Step-by-step explanation:
This is because of the placement. That is all there is to it really. 5$ is a singular cost to enter the store while the 3$ will be multiplied by S amount of shorts. Adding these two costs will get the total cost or as shown by the equation, Cs.
Answer:
It would be less than 0.05.
Step-by-step explanation:
The hypothesis test was done to claim that the weight of participants has changed.
The null and alternative hypothesis could be written as:
being μ the population mean change in weight.
With that information, we can tell that is a two tailed test. Sample means that fall in any of the tails, with a z-statistic over 1.96 or under -1.96 (at a significance level of 0.05), will be evidence to reject the null hypothesis.
The information we have about the sample is the 95% confidence interval calculated from the sample information.
This confidence interval does not include the value μ=0.
Then, there is 2.5% of probabiltity that the population mean is under 2.177, the lower bound of the interval, which includes the value μ=0.
With this information, we can conclude that the P-value have to be under 0.05.
Arrange your given equation to resembles the form
a^2 +2ab+ b^2 because this equals (a+b)^2
So we get:
y^2+16y+8^2=0
Now compare
y^2+16y+8^2 to a^2 +2ab+ b^2
So we got
y^2+2•8 y+8^2=0 which equals (y+8)^2
