Answer: y=-(1/8)x+(21/2)
Explanation:
The new equation’s slope needs to be perpendicular to y=8x-1
To get the new slope, we take the negative reciprocal of the slope from above
8 —> -1/8
Now we have y=-(1/8)x+b but it needs to pass through (4,10), so we need to find the value of b that makes this possible.
Since (4,10) is in the form of (x,y) we can plug in these values into the new equation to solve for b:
y=-(1/8)x+b
10=-(1/8)4+b
10=(-1/2)+b
b=(21/2)
Now put b back into the new equation
y=-(1/8)x+b
y=-(1/8)x+(21/2)
The question is: If the student is known to be the girl (300 girls) what is the probability of being right handed.
We know that there are 300 girls, and that out of those 300, there are 250 girls right handed.
Divide 250 with 300
250/300 = 0.83333, or 83.33%
0.83333, or 83.33% is your answer

Answer:
13.8654599313 and -0.8654599313
Step-by-step explanation:
If one of the numbers is x, then the other is 13-x, and their product is ...
x(13 -x) = -12
x^2 -13x = 12 . . . . multiply by -1 and simplify
x^2 -13x +6.5^2 = 12 +6.5^2 . . . . complete the square
(x -6.5)^2 = 54.25
x -6.5 = √54.25
x = 6.5 +√54.25 ≈ 13.8654599313
and the other number is ...
13 -x = 13 -13.8654599313 = -0.8654599313
The two numbers are 13.8654599313 and -0.8654599313.
Answer:
False.
Step-by-step explanation:
Integers are numbers in this set:
{...,-3,-2,-1,0,1,2,3,...}
The opposite of a number is you just changing the sign of that number. Unless you are asking for the opposite of 0 which is just 0.
Example: The opposite of 5 is -5.
Example: The opposite of -5 is 5.
So the opposite of an integer does not always mean the result will be negative. As you seen above, it could be 0, positive, or negative.
