Answer:
The number of cookies baked is 50
Step-by-step explanation:
Given as:
Lacey baked 20 cookies with 2 scoops of flour
∵ For 2 scoops of flour , The number of cookies baked is 20
so,For 1 scoops of flour , The number of cookies baked is 
∴ For 5 scoops of flour , The number of cookies baked is × 5
I.e Number of baked cookies = 10 × 5 = 50
Hence The number of cookies baked is 50 Answer
Answer:let
Length =L
Width =W
L=5W
Perimeter(p)=2L+2W
P=10W+2W
84=12W
Divide both sides by 12
W=7m
L=5*7=35m
Hence, the length and width are 35m and 7m respectively
Step-by-step explanation:
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).
