What is the sample variance of the following data, which describe the height growth of 10 foxtail pine trees grown in a common garden ( give your answer to one decimal place)?
Tree Height(cm)
1 25.6987
2 19.6587
3 11.4780
4 9.11130
5 16.8747
6 14.7771
7 33.0001
8 24.0000
9 19.4441
10 14.1010
answer 51.9
Explanation:
what is a sample variance?
A sample variance (denoted as 
) is used to calculate how far a set of numbers are from the mean value of the set. Mathematically, it is defined as the average of the squared deviations from its mean value.
Let the individual value of the trees be represented as x₁ to x₁₀
Let the total number of Foxtail pine trees be N
To calculate the standard deviation, we will first calculate the mean or average of the height of the trees
1. Mean (μ) = 
= 
= 
2. we need to calculate the sum of the squares of the individual deviations.
∑[x-μ]²= 
3. Now the variance is ; (∑[x-μ]²) ÷ (N-1) and since N=10, then N-1 = 10-1 = 9
= 
we were asked the give our answer to one decimal place
∴ Variance()= 51.9
In the field of medicine we have a short adage that goes, "To cure sometimes, to treat often, to comfort always." Some say it was Hippocrates himself who said this. With that in mind, doctors should always have the patient's welfare in mind always. To improve relations with the patient, the doctor must do a lot of things to show respect. One of them includes simply sitting on a chair with an open stance and leaning slightly forward at an angle while the patient is talking to show that you are interested in what he or she has to say. Never hold the door knob while the patient is still talking as this is a sign that you want him to leave as soon as possible. Never look at far away things, like paintings on the wall or a clock, while the patient is talking because this is another sign of disinterest. And always allow the patient to express his or her self fully without interruption. There are more ways to improve patient relations but these are some good pointers to begin with.
Gregor Mendel was an important scientist, considered to be the founder of the science of genetics. His experiments on the crossbreeding of plants and the passing down of favourable traits, led him to establish the laws of Mendelian inheritance. He was using pea plants for his experiments and he was studying seven different pea traits: pea shape and color, pod shape and color, flower color, plant size and position of flowers.
After a steroid hormone binds to its intracellular receptor, transcription of specific genes occurs. The activated receptor moves into the nucleus and binds to DNA
<h3>What is steroid hormone and intracellular receptor ?</h3>
Target cells have steroid hormone receptors in their nuclei, cytoplasm, and plasma membranes. They are typically intracellular receptors (often cytoplasmic or nuclear) that start the signalling processes for steroid hormones, which modify the expression of genes over the course of hours to days.
- By attaching to intracellular receptors, steroid hormones control cellular functions by changing the expression of specific nucleotide sequences. Since the majority of steroid receptors in target cells reside in the cytoplasm, they must enter the nucleus to change gene expression.

Answer:
Cyclical changes in eccentricity are changes in the shape of Earth's orbit.
Changes in obliquity are the changes in Earth's tilt on its axis.
Earth also experiences a precession around its axis.
The cycles affect climate by altering the duration of Earth's seasons and temperature decreases between summer and winter
