Answer:
10
Step-by-step explanation:
1 out of 50 got it, so 500/50=10
Step-by-step explanation:
m=5/7
m1=m2=5/7
L;y-(-2)=5/7(x-(-5)
y+2=5/7(x+5)
7y+14=5X+25
7y-5x=11 is parallel lines
m1*m2=-1 is perpendicular lines
m2=-1*7/5
m2=-7/5
L;y+2=-7/5(x+5)
5Y+10=-7x-35
5y+7x=-45 is perpendicular lines
Answer:
If something is guaranteed, it has a probability of 100%, or 1.
Step-by-step explanation:
A standard deck has 52 cards. Of these, half are red cards (diamonds and hearts) and half are black cards (clovers and spades)
Half of the deck is 26 cards (52 ÷ 2 = 26), so you have 26 red and 26 black cards.
What this means in our context is, if we draw 27 cards, even if we drew all 26 black cards, we would still have 1 red card.
So the probability is 100%, or 1, of drawing a red card when we pick 27 cards from a deck, no matter how it's shuffled
Answer:
r = 7t
or not mathematically,
r(t) = 7t
r(t) means, r, which is a function of t.
Step-by-step explanation:
Initial size of the radius = 0 cm, at t = 0 s
Rate of increase of the radius of the circle = 7 cm/s
dr/dt = 7
dr = 7 dt
∫ dr = 7 ∫ dt
r = 7t + C (C is the constant of integration)
At t = 0, r = 0,
0 = 0 + C
C = 0
r = 7t.
r(t) = 7t
