P(no girls in five births) = p(five boys) = (1/2)^5 = 1/32 = 0.0313
Answer:
the equation is : x²-x-12
Step-by-step explanation:
the quadratic equation is in the form of : y=ax²+bx+c
the product of the zeros is -12 and the sum is 1
b = - 1
c=-12 (product)
y=x²-x-12
check : factorize first (x+3)(x-4)=0
either x+3=0 then x=-3
or x-4=0 then x=4
-3*4=-12
-3+4=1
the equation is : x²-x-12
2n + 20 = -2
20 + 2 = -2n
22 = -2n
22/2 = n
11 = n
Answer:
(-3,-6)
Step-by-step explanation:
The first coordinate is the x coordinate
X is 3 units to the left so it is -3
The next coordinate is the y coordinate
Y is 6 units down so it is -6
(-3,-6)
To write the following as a fraction, we will;
First write the decimal over 1
That is;
Then multiply the numerator and the denominator by 100
Now, go ahead and reduce the fraction
