Answer:
that is the ten thousands place
Step-by-step explanation:
The equation for a perpendicular line through the origin can be written by swapping the x- and y-coefficients and negating one. When you do that, you get ...
C. 2x + 5y = 0
Answer:
The value of P(A ∪ B) is 0.682 to the nearest thousandth
Step-by-step explanation:
The addition rule of probability is:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B), where P(A ∪ B) is probability A or B , P(A ∩ B) is probability A and B
∵ P(A) = 0.33
∵ P(B) = 0.6
∵ P(A ∩ B) = 0.248
- Substitute these values in the rule above
∴ P(A ∪ B) = 0.33 + 0.6 - 0.248
∴ P(A ∪ B) = 0.682
The value of P(A ∪ B) is 0.682 to the nearest thousandth
Answer:
- x = 0 or 1
- x = ±i/4
- x = -5 (twice)
Step-by-step explanation:
Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.
1. x^2 -x = 0
x(x -1) = 0 . . . . . x = 0 or 1
__
2. 16x^2 +1 = 0
This is the "difference of squares" ...
(4x)^2 - (i)^2 = 0
(4x -i)(4x +i) = 0 . . . . . x = -i/4 or i/4 (zeros are complex)
__
3. x^2 +10x +25 = 0
(x +5)(x +5) = 0 . . . . . x = -5 with multiplicity 2
Harry's Answer:
8-(2+5)8-(2+5) = 8-(16+40)-(2+5) ⇒ 8 - 16 - 40 - 2 - 5 = -55
Terry's Answer:
8 - 2 + 58 - 2 + 5 = 67
H = -55
T = 67
H - TH - T
-55 - (67*-55) - 67 = -55 - (-3685) - 67 = -55 + 3685 - 67 = 3,563
