Answer:
<em>z-score will be: 7.741.... and it will be unusual. </em>
Step-by-step explanation:
Human body temperatures have a mean of 98.20 degrees Fahrenheit and a standard deviation of 0.62 degrees Fahrenheit.
So here, and
<u>Formula for z-score</u> is:
Thus, the z-score for 103.00 degrees Fahrenheit will be.......
As, here the z-score is more than 2 standard deviations above the mean, so 103.00 degrees Fahrenheit is unusual for human body temperature.
The equation of constant of proportionality will be y = 2.5x.
Given A 2-column table with 3 rows. Column 1 has entries 2, 4, 5. Column 2 has entries 5, 10, 12.5.
Equation of two variables look like ax+by=c. It can be a linear equation,quadratic equation,cubic equation.
Equation from two points can be found out by putting the values of points in the formula given below:
in which
are the end points of the line.
Equation of constant proportionality looks like:
k=y/x
in which k is slope which is to be find out according to the same formula as we find in the equation of line.
Slope from (2,5),(4,10) is (10-5/4-2)
=5/2
=2.5
Put the value of k=2.5 in formula of slope.
2.5=y/x
2.5x=y
y=2.5x.
Hence the equation of constant of proportionality is y=2.5x.

if you've read those links already, you'd know what we're doing here.
we'll move the repeating part to the left-side of the dot, by multiplying by "1" and as many zeros as needed, or 10 at some power pretty much.
on 0.13 we need 100 to get 13.13.... and on 0.1234, we need 10000 to get 1234.1234....
Answer:
f(x) = 3 if x ≤ -2
= 1 if x > -2 ⇒ attached figure
Step-by-step explanation:
* Lets explain how to answer the question
- For the part of the graph on the left side (2nd quadrant)
- There is a horizontal line start from x = -∞ and stop at x = -2
- The end of the line is black dot means x = -2 belongs to the function
- The horizontal line drawn at y = 3
∴ The equation of the horizontal line is y = 3
∴ The function represents this part of graph is y = 3 if x ≤ -2
- The other part of the graph is also horizontal line start from
x = -2 to x = ∞
- The end of the line is white dot means x = -2 does not belong
to the function
- The horizontal line drawn at y = 1
∴ The equation of the horizontal line is y = 1
∴ The function represents this part of graph is y = 1 if x > -2
* f(x) = 3 if x ≤ -2
= 1 if x > -2
- The answer is attached
