Petra randomly selects a card from a standard deck of 52 playing cards. What is the percent probability that the card shows a re d number greater than 6? Express your answer to the nearest hundredth
1 answer:
Half of the cards in the deck of 52 are red. There are 14 cards that are both red AND greater than 6. 14/52≈0.27. Hope this helps!

Hello :D
£8000 - £2000 = £6000
6 x 500 = £3000
£6000 - £3000 = £3000
Answer:
measure of a angle 1 = x
measure of angle 2= 3x
3x+1x=180 ( linear pair)
4x=180
x= 180÷4
x= 45
angle one = x= 45
angle two = 3x = 3×45= 135
the 2 angles are
45 and 135
First, set up the formula.
Answer:
<h3>Question 1</h3>
sec²θ + cosec²θ = 1/cos²θ + 1/sin²θ = (sin²θ + cos²θ)/(sin²θcos²θ) = 1 / (sin²θcos²θ) = [(sin²θ + cos²θ)/sinθcosθ]² = (sinθ/cosθ + cosθ/sinθ)² = (tanθ + cotθ)² <h3>Question 2</h3>
(1 - tan²θ) / (1 + tan²θ) = (1 - sin²θ/cos²θ) / (1 + sin²θ/cos²θ) = (cos²θ - sin²θ) / (cos²θ + sin²θ) = (cosθ + sinθ)(cosθ - sinθ) / 1 = (cosθ + sinθ)(cosθ - sinθ) <h3>Question 3</h3>
sinθ/ (1 - cotθ) + cosθ / (1 - tanθ) = sinθ / (1 - cosθ/sinθ) + cosθ / (1 - sinθ/cosθ) = sinθ/ [(sinθ - cosθ) / sinθ] + cosθ / [(cosθ - sinθ)/cosθ] = sin²θ/ (sinθ - cosθ) + cos²θ/(cosθ - sinθ) = sin²θ/ (sinθ - cosθ) - cos²θ/(sinθ - cosθ) = (sin²θ - cos²θ) / (sinθ - cosθ) = (sinθ + cosθ)(sinθ - cosθ) / (sinθ - cosθ) = sinθ + cosθ
