Piece-wise functions evaluating problems how do i plug in numbers?

Mathematics

White raven [17]3 years ago

F(10) means they want you to plug in 10. The piecewise function tells you that when x is greater or equal to 3, you use 6-2x. What I am saying is that since the number you want to plug in is greater than 3, then you plug in 10 into 6-2x.

f(10)=6-2*10=-14

How to find the area under the standard normal curve between z 1.5 and z 2.5?
alisha [4.7K]
It is possible to calculate mathematically the area under the normal curve between any two values of z.
However, tables/software have been developed to give the areas under the normal curve to the left of particular values of z.  The function is the probability of Z<z, or P(Z<z).
The area between two values z1 and z2 (where z2>z1) is therefore 
P(Z<z2)-P(Z<z1).

For example, to find the area between  z1=1.5, z2=2.5
is 
P(Z<2.5)-P(Z<1.5)
=0.99379-0.93319
=0.06060

(above values obtained by software, such as R)
For example, the value P(Z<2.5) can be calculated using
P(Z<2.5)=erf(2.5/sqrt(2))/2+1/2
where erf(x) is a mathematical function that does not have an explicit formula (calculated by summation of series, or tabulated).

The regular octagon shown is divided into 8 congruent triangles. Each triangle has an area of 21.7 square centimeters. The
neonofarm [45]
I believe the formula to find the height would be h= 2a/b and if you use that formula and plug in the area (21.7) of each triangle as well as the base (6) then you would get a height of 7.2 cm. I hope this is correct! :)

Find the unknown length in the right triangle 27cm and 13 cm
Phoenix [80]

use pythagoras:

{c}^{2}  = \:   {b}^{2}  -  {a}^{2}

c^2 = (27)^2 - (13)^2

c^2 = 560

c = 23.6643....cm

If 20 were added to each of the vlaues in a data set that originally had a standard deviation of 8, the standard deviation of th
Nitella [24]

Answer:

False (I assume it's a true/false question)

Step-by-step explanation:

Standard deviation measures how spread out the data is.  If you add 8 to all the data values, the distribution of data moves to the right (on a graph) 8 units. The shifted data are no more and no less spread out than before.  The standard deviation does not change.
