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:
A) Approximate percentage of women with platelet counts within 2 standard deviations of the mean, or between 118.5 and 377.3 = 95%
B) approximate percentage of women with platelet counts between 53.8 and 442.0 = 99.7%
Step-by-step explanation:
We are given;
mean;μ = 247.9
standard deviation;σ = 64.7
A) We want to find the approximate percentage of women with platelet counts within 2 standard deviations of the mean, or between 118.5 and 377.3.
Now, from the image attached, we can see that from the empirical curve, the probability of 1 standard deviation from the mean is (34% + 34%) = 68 %.
While probability of 2 standard deviations from the mean is (13.5% + 34% + 34% + 13.5%) = 95%
Thus, approximate percentage of women with platelet counts within 2 standard deviations of the mean, or between 118.5 and 377.3 = 95%
B) Now, we want to find the approximate percentage of women with platelet counts between 53.8 and 442.0.
53.8 and 442.0 represents 3 standard deviations from the mean.
Let's confirm that.
Since mean;μ = 247.9
standard deviation;σ = 64.7 ;
μ = 247.9
σ = 64.7
μ + 3σ = 247.9 + 3(64.7) = 442
Also;
μ - 3σ = 247.9 - 3(64.7) = 53.8
Again from the empirical curve attached, we cans that at 3 standard deviations from the mean, we have a percentage probability of;
(2.35% + 13.5% + 34% + 34% + 13.5% + 2.35%) = 99.7%
