Answer:
350%
Step-by-step explanation:
540 - 120 = 420
420/120 = 3.5
3.5 × 100 = 350%
Rewrite
(4)(3.63) * (10^4)(10^-4)
multiply
14.52 * (10^4)(10^-4)
multiplication of the coefficient is the addition of the exponent
so 4 -4 is 0
14.52
Hope this helps :)
Total number of cards in a deck = 52
Number of red cards = 26
Number of black cards = 26
P(a red card, then a black card) = (26/52)(26/52) = 1/4
Answer: 1/4
F(x) = x² + 4
y = x² + 4
First, I reverse the equation to be
x² + 4 = y
Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)
Last, change into invers function
f⁻¹(x) = √(x - 4)
X = ± √<span>6 </span><span>= ± 2.4495 because i know it</span>
