Answer:
7+3=10 i know that because I used a calculator
Answer:
Null hypothesis: H₀: ∪ = ≤ 393 pounds
Alternative hpothesis Hₐ: ∪ > 393 pounds
Step-by-step explanation:
The null hypothesis in this case is
Null hypothesis: H₀: ∪ = ≤ 393 pounds
Agriculture Scientists wish to test against this claim believing that the new fertilizer may increase the yield, thus the alternative hypothesis will be
Alternative hpothesis Hₐ: ∪ > 393 pounds.
22490 x 1.055 = 23726.95 is the total cost including sales tax
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx
where
k is the constant of proportionality
Verify each table
table a
Let
x ----> distance
y ----> sound level
For each ordered pair calculate the value of k
k=y/x
so
(5,85) -----> k=85/5=17
(10,79) ----> k=79/10=7.9
the values of k are differents
that means
the table nor represent a proportional relationship
table b
let
x ----> volume
y ----> cost
k=y/x
(16,1.49) ----> k=1.49/16=0.093125
(20,1.59) ----> k=1.59/20=0.0795
the values of k are differents
that means
the table nor represent a proportional relationship
