Answer:
2.275% of this population has a diastolic blood pressure less than 60 mmHg
Explanation:
Hello!
Yo have the distribution of the diastolic blood pressure in a certain population. Be X: diastolic blood pressure of an individual, X~N(μ;δ²)
Where
μ= 82mmHg
δ=11 mmHg
You need to calculate the probability of an individual of this population having less than 60mmHg diastolic blood pressure.
Symbolically:
P(X<60)
To obtain the value of probability you need to standardize the value of diastolic pressure so that you can obtain it from the standard normal distribution. The way to standardize the value is to subtract the mean and divide by the standard deviation
Z= (X-μ)/δ~N(0;1)
P(Z<(60-82)/11)
P(Z<-2)= 0.02275
I hope it helps!
Answer:
The correct answer is - divergent.
Explanation:
A divergent plate boundary is plate boundary that is form by the sepration of the two distinct tectonic plates away from one another and result in the forming the ranges known as oceanic spreading ridges.
This type of plate boundary occurs due to the earthquack or volcanic erruption of from the mantle to surface of the earth. This magma or rises and forms oceanic crust by the solidifying of the moleten rocks.
The correct answer is Soluble phosphorous
Soluble phosphorus is a measure of orthophosphate (PO4), the
soluble and inorganic filterable fraction of phosphorus, which is the most
stable type of phosphate and it is the form directly used up by the plant
cells.
Viruses are classified as non-living.

The answer is <span>C. Change in odor.
There are several signs of chemical reaction:
1. Dissolved precipitate.
2. Formation of gas (bubbles).
3. Change of color.
4. Change of temperature (warming or cooling).
5. Production of energy.
Among these signs, there is no change in odor, which is, thus, the right choice.</span>
