Answer:
x^2/20+y^2/20=1
Step-by-step explanation:
This graph tells us that x^2/20+y^2/20=1 is the correct choice
Solution:
Probability of a basketball player scoring on any shot = .75
Probability of a basketball player does not hit on the right point = 1-0.75=0.25
Probability that it will take her more than four shots to first scores on a shot = F F F F S +F F F F S S+ F F F F S S S+ F F F F S S S S F F F F S SS SS+...........
= F F F F S[1+S+S S+S S S+ S S S S+.......upto infinity]
= F F F F S [],→→→[ sum to infinity of a geometric progression a+a r+ a r²+ a r³,... .....= [], ]
= (0.25) × (0.25) ×(0.25)× (0.25)×(0.75)×[],
= 0.0625 × 0.25×0.75
=0.01171875
= 0.0118 (Approx)→→→→Option (d) is correct .
The answer would be 12/20
Simplified: 3/5
Answer:
has a remainder of 7 ⇒ B
Step-by-step explanation:
In m ÷ n = c + ,
Let us use the facts above to solve the question
∵ has a remainder of 5
→ Let us find the first number divided by 8 and give a reminder of 5
that means let the quotient = 1
∵ n = (8 × 1) + 5 = 8 + 5
∴ n = 13
∵ has a remainder of 7
→ Let us find the first number divided by 8 and give a reminder of 7
that means let the quotient = 1
∵ n + x = (8 × 1) + 7 = 8 + 7
∴ n + x = 15
∵ n = 13
∴ 13 + x = 15
→ Subtract 13 from both sides
∴ 13 -13 + x = 15 - 13
∴ x = 2
∴ has a remainder of 7
