I believe the answer is A because you cannot find x nor y
There are 3 lines of reflectional symmetry in an equilateral triangle
Answer:
y = 3/8x +29/8
Step-by-step explanation:
First we need to find the slope
m= (y2-y1)/(x2-x1)
= (1-4)/(-7-1)
= -3 /-8
= 3/8
Then we can use the slope intercept form of the equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 3/8x +b
Substitute a point into the equation to find b
4 = 3/8(1) +b
Subtract 3/8 from each side
32/8 -3/8 = 3/8-3/8+b
29/8 = b
Substitute b back into the equation
y = 3/8x +29/8
Answer:
(C) No, since 0.47 is not equal to 0.13.
Step-by-step explanation:
We have two events, A and B.
I am going to say that P(A) is the probability that a president is left-handed.
I am going to say that P(B) is the probability that a president is a Democrat.
P(B/A) is the probability that the probability that the president is a Democrat, given that he is left-handed.
If P(B/A) = P(A), then the events are independent.
In this problem, we have that P(B/A) = 0.13 and P(A) = 0.47. So, "being left-handed" is not independent of "being a Democrat" and the correct answer is
(C) No, since 0.47 is not equal to 0.13.
Answer:
x = 4.25
Step-by-step explanation:
First, alter the equation until both exponents have the same base. We know that 9^3 is 27. Therefore, we can change 27^(x-3) into 9^3(x-3).
Now, the equation can be written as 9^(8-x) = 9^(3x-9)
Now that the bases are the same, we can cancel them out and just solve for the exponents. This will look like:
8-x = 3x-9.
8 = 4x - 9
17 = 4x
x = 4.25
