Answer:
Step-by-step explanation:
I think you mean
Since the variable parts are the same, the terms are like terms and can be combined together.
Answer:
2.4%
Step-by-step explanation:
We make use of the binomial probability equation, which is as follows:
P = [n! / (n - r)! r!] p ^ r * q ^ (n - r)
where,
n total number samples = 20
r is the selected number = 8
p, sin este valor no se puede realizar el ejercicio y no lo mencionas, pero encontré una pregunta igual y era de 20.37%, es decir 0.2037
q = 1 - 0.2037 = 0.7963
reemplazando:
P = [20! / ((20 - 8)! * 8!)] * [0.2037 ^ 8 * 0.7963 ^ (20 - 8)]
P = 125970 * 1.92685405*10^-7
P = 0.024 = 2.4%
Answer:
perpendicular bisector
Step-by-step explanation:
AD = DB because of their marks.
If AD = DB, then AB has a bisector of point D.
A line would form between DH to make them a perpendicular bisector.
Answer:
<u>The last step in solving this equation was D. Divide both sides of the equation by 3</u>
Step-by-step explanation:
For finding the solution, let's solve the equation:
7/8 = 3x - 5/11
-3x = - 5/11 - 7/8
-3x = (-40 - 77)/88 (Subtracting at the right side of the equation)
-3x = -117/88
3x = 117/88 (Multiplying by - 1 at both sides of the equation)
x = (117/88)/3 (Dividing by 3 at both sides of the equation)
<u>x = 117/264</u>
<u>The last step in solving this equation was D. Divide both sides of the equation by 3</u>
Parallel lines slope are the same. Slope of parallel line is -2.
y=mx+b (put value of c and slope to find b)
7=-2x3+b
7=-6+b
7+6=b
13=b
Therefore the equation is y=-2x+13
