I need help with this math question :(
1 answer:
Answer:
k = 5,
y = 5x
Step-by-step explanation:
If y is proportional to x,
y ∝ x
Then the equation will be
y = kx
Her k = proportionality constant.
Now we choose a point from the given table.
Let the point is (2, 10).
By putting the values of x and y in the equation,
10 = 2×k
k =
k = 5
This will be true for any point we choose from the table.
And the equation will be y = 5x

Answer:
Step-by-step explanation:
From the given information;
The null and alternative hypothesis is:
sample mean x = -2
population mean = 0
SD = 6
sample size n = 25
Using t-test statistics:
t = -1.667
P-value = P(t ≤ -1.667) + P(t ≥ 1.667)
P-value = 0.1086
Since P-value is greater than , we fail to reject
