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 answer would be negative fifty two
-52
X+58=6
58-6=52
So the answer would be negative 52
Answer:
273.7
Step-by-step explanation:
first fine the sides that isn't the base.
triangle area formula: (b*h)/2
(14*9)/2 = 63
since there are 3 sides you multiply this by three.
63*3=189
then find the base.
same formula since its a triangle.
(12.1*14)/2 = 84.7
now add them both up:
84.7+189 = 273.7
hope this helps!
