Experimental probability = number of positive results / number of experiments
Experimental probability = 67 / 450
Answer:
B ( 92 degrees)
Step-by-step explanation:
1. Find y
In order to find z, we need to find y.
All triangles add up to 180 degrees, so y would be
180 - (48 + 44) = 88
y is 88 degrees
2. Find z
So now we know y is 88, we can find z
The circle of all angles of y and z = 360 ( because full angle)
so our equation is:
(88 + z)2 = 360
Divide by 2
88 + z = 180
z = 92
4(1.75y−3.5)+1.25y
. First multiply through with 4 the numbers in the parentheses.
7y➖ 14 ➕ 1.25y
add 1.25y to 7y
That will be 8.25y
So the answer will be 8.25y ➖ 14

Answer:
x = -7
Step-by-step explanation:
2x+6 = x-1
add -6 to both sides
2x = x-7
add -x to both sides
x = -7
