M is the midpoint of AC.
So, MA = MC
M is the midpoint of BD.
So, MB = MD
Also, since the midpoints of AC and BD coincide,
AC bisects BD and BD bisects AC.
Hence, our conjecture is MA = MB = MC = MD.
Answer:
The number of bicycles in the store is 
Step-by-step explanation:
Let
x------> the number of bicycles
y-----> the number of tricycles
we know that
The bicycles has two wheels and the tricycles has three wheels
so
------> equation A
------> equation B
substitute equation B in equation A and solve for y
Find the value of x
To determine the probability that exactly two of the five marbles are blue, we will use the rule of multiplication.
Let event A = the event that the first marble drawn is blue; and let B = the event that the second marble drawn is blue.
To start, it is given that there are 50 marbles, 20 of them are blue. Therefore, P(A) = 20/50
After the first selection, there are 49 marbles left, 19 of them are blue. Therefore, P(A|B) = 19/49
Based on the rule of multiplication:P(A ∩ B) = P(A)*P(A|B)P(A ∩ B) = (20/50) (19/49)P(A ∩ B) = 380/2450P(A ∩ B) = 38/245 or 15.51%
The probability that there will be two blue marbles among the five drawn marbles is 38/245 or 15.51%
We got the 15.51% by dividing 38 by 245. The quotient will be 0.1551. We then multiplied it by 100% resulting to 15.51%
ANSWER:
The 1st one: -3x + y = 5
ABOUT STANDARD FORM:
- Ax + By = C
- A & B & C are integers
- A & B are both non - zero
- This form is good to use when wanting to find the x & y intercepts of a line
y - 2 = 3(x + 1) --- IN POINT SLOPE FORM
y - 2 = 3x + 3
+ 2 + 2
y = 3x + 5 --- IN SLOPE INTERCEPT FORM
-3x -3x
-3x + y = 5 --- STANDARD FORM
Hope this helps you!!! :)
Answer:
85in²
Step-by-step explanation:
s = side
triangle: ((b x h) ÷ 2) x 4
((5 x 6) ÷ 2) x 4 = 60in
square: s2(squared not 2)
5² = 25
total sa: 25 + 60 = 85in²
