Step-by-step explanation:
√7 * √7 = 7 , which is not a irrational number
Its formed by the 3 altitudes
Hello there!
The right prime factorization is
2*2*2*3*11 because 2 and 3 and 11 are prime.
Take a look at the words "prime" and "factorization"
Can you see something that looks like "prime factors?" Exactly!
2 is prime. 3 is prime. 11 is also prime.
A prime number is only divisible by 1 and itself.
What is the value of 5+2*15+(12*4)?
If you remember "Please Excuse My Dear Aunt Sally" that's great as long as you know what that means.
P = Parentheses
E=Exponents
M=Multiplication
D=Division
A=Addition
S=Subtraction
5+2*15+(12*4)=5+2*15+(48)=5+30+48=83
A farmer has 40 tomatoes in a basket. 18 were green. How many were red?
18 green
40 total
Red
40-18=22
Hope this helps
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).
D= sqrt( (6-4)^2 + (5sqrt2 - 3sqrt2)^2 )
It's d= 3,46 i think
