Answer:
1. proportional relationship
2. constant of proportionality
3. unit rate.
I'm not exactly sure on these answers, so please double check them for me to make sure that they are correct.
Step-by-step explanation:
Y² = 12
y = 2√3
x = √6
Now, 4 /xy
= 4/2√3√6
= 2 / 3√2
= √2/3
In short, Your Answer would be √2 / 3
Hope this helps!
Answer:
36
Step-by-step explanation:
Since f(x) varies directly with x, f(x) can be expressed alternatively as \[f(x) = k * x\] where k is a constant value.
Given that f(x) is 72 when the value of x is 6.
This implies, \[72 = k * 6\]
Simplifying and rearranging the equation to find the value of k:
k = \frac{72}{6}
Hence k = 12
Or, \[f(x) = 12 * x\]
When x = 3, \[f(x) = 12 *3 \]
Or in other words, the value of f(x) when x=3 is 36
Answer:
z = -0.4.
Step-by-step explanation:
Here's the formula for finding the z-score (a.k.a. standardized normal variable) of one measurement 
of a normal random variable 
:
,
where
is the z-score of this measurement, - is the value of this measurement,
is the mean of the random normal variable, and
is the standard deviation (the square root of variance) of the random normal variable.
Let the length of a trout in this lake be 
inches.
.
, and
.
For this measurement, 
. Apply the formula to get the z-score:
.
