Answer:
Negative Binomial
Step-by-step explanation:
The girl receives only 5% of mail which are addressed to her. Rest of 95% mails belong to other family members.
P (X) = 5%
P (X) = 95 / 5
P (X) = 19
The family receives 19 mails out of which only 5% will address the girl. The all other mails belong to the other family members.
Answer: m=44
Step-by-step explanation:
1/2m-3/4n = 16
1/2m-3/4(8) = 16
1/2m-24/4 = 16
1/2m-6 = 16
1/2m = 22
m=44
The Great common factor is 3.
So divide both numerator and denominator by 3 and you have -5.2.
The correct equation is 8.7 + b = 54.6
because it is given that measure of side a is 8.7cm, in all other equations the values of a is different.
from the first equation we can find the value of b, that is
b = 54.6 - 8.7 = 45.9
so, value of b is 45.9cm
FOIL when multiplying two binomials.
First:
√ 3*√ 3= 3
Outer:
√ 3 *2 = 2√3
Inner:
-4*√3= -4√3
Last:
-4*2=-8
Put it together
3+2√3-4√3-8
Simplify
(-2√3)-5
Final answer: (-2√3)-5
