Answer:
15 + 3n
Triple the amount of evening which is “n” so it would “3n”
The morning amount would still be 15
Answer:
a) P value = 0.0013
b) No, it is not plausible that the silicon content of the water is no greater than it was 10 years ago
Step-by-step explanation:
The null hypothesis here is “Mean is equal to 5” while alternate hypothesis is that “Mean is greater than 5”
Given
Mean = 5, x’ = 5.4 and sigma = 1.2 and n = 85
Z = x-u’/sigma/sqrt n
Substituting the given values, we get –
Z = 3.02
A) P value = 0.0013 which is less than 0.05 and thus we will reject the null hypothesis
B) There is enough evidence to reject the null hypothesis
Answer:
The function f(x) translated left by 5 units and then it is reflected across the x-axis.
Step-by-step explanation:
The original equation of the graph of the function is f(x) = x ........ (1)
If we replace f(x) by [- f(x) + 5] then the equation becomes - f(x) + 5 = x
⇒ f(x) = - (x - 5) ..... (2)
So, comparing equations (1) and (2), we can conclude that the graph of the function f(x) translated left by 5 units and then it is reflected across the x-axis. (Answer)
