Answer:
Constant of proportionality is 190.
Step-by-step explanation:
To find proportionality constant we will find difference of weights after 2 days and at birth.
Now we will find difference of weights after 14 days and at birth. We will divide the difference by 14.
We can see that weights are increasing at a constant rate of 190 pounds per day. Therefore, our constant of proportionality is 190.
Answer:
The constant of proportionality is 190.
Step-by-step explanation:
A baby blue whale weighed 5520 pounds at birth.
After two days, the baby weighed 5710.
Means the weight gain is : pounds
After 14 days, the baby weighed 8180 pounds.
Weight gain = pounds
So, per day gain = pounds
Hence, the constant of proportionality is 190.

Answer:
Explained below.
Step-by-step explanation:
(1)
The confidence level is, 91%.
Compute the value of α as follows:
(2)
As the population standard deviation is provided, i.e. <em>σ</em> = 256 psi, the <em>z</em> value would be appropriate.
The <em>z</em> value for α = 0.09 is,
<em>z</em> = 1.69
(3)
Compute the 91% confidence interval as follows:
(4)
The 91% confidence interval for population mean implies that there is a 0.91 probability that the true value of the mean is included in the interval, (2942.29, 3057.71) psi.
Given
Area of the regular pentagon is 6.9 cm².
Find out the perimeter of a regular pentagon
To proof
Formula
Area of regular pentagon is
As given in the question
area of regular pentagon = 6.9 cm²
now equating the area value with the area formula.
Now put
√5 = 2.24 ( approx)
put in the above equation
thus
a² = 4.01
a = √ 4.01
a = 2.0 cm ( approx)
As perimeter represented the sum of all sides.
i.e regular pentagon have five sides of equal length.
Thus
perimeter of the regular pentagon = 5 × side length
= 5 ×2.00
therefore the perimeter of the regular pentagon = 10cm
option c is correct
Hence proved
