If y is directly proportional to x and y = 11 when x = 6 , what is the value of y when x = 9

Mathematics

REY [17]3 years ago

Since we are given that y is directly proportional to x and that when y = 11, x equals 6, we can set up a proportion. Before doing that however, we need to note that the question is asking for the value of y when x = 9. Here is the equation:
\frac{11}{6} = \frac{y}{9}
Now, just cross multiply and solve for y to get a value of 16.5. Therefore, the value of y when x = 9 is 16.5. Hope this helped and have a phenomenal day!

Tema [17]

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
