Given:
The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas.
To find:
The constant of proportionality
Solution:
We have,
...(i)
where P is the price and n is the number of bananas.
Price P is directly proportional to the number of bananas. So,
...(ii)
Where, k is the constant of proportionality.
On comparing (i) and (ii), we get
Therefore, the constant of proportionality is 0.25.
Answer:
x can be cancelled
Step-by-step explanation:
we are given
Firstly, we will factor numerator and denominator
and then we can factor it
now, we can factor denominator
now, we can replace it
we can see that
both terms are having x common
so, x can be cancelled
So,
x can be cancelled
Answer:
Step-by-step explanation:
Hypothesis testing
For this problem, we need to use the t-student distribution to make inference about the data. We calculate the t-statistics as below:
Using a t-statistics table, or using the function TDIST in Microsoft Excel with with two-tailed distribution, we obtain
