Answer:
They are 108 8th graders at Jefferson Middle School
Step-by-step explanation:
324 x 5/12 = 135 7th graders
324 x 3/12 = 81 9th graders
324 x 4/12 = 108 8th graders
Use the distance formula?
Answer:
3/4
Step-by-step explanation:
Probability is the likelihood of an event.
No.of favourable outcomes/ Total no. of outcomes
Probability of coin selection : [Both coins have equal likelihood of being chosen]
- Prob( Coin A Selection) = 1/2
- Prob (Coin B selection) = 1/2
Probability of head & tail by both coins :
- Prob (Head / Coin A) = 1/4
- Prob (Tail / Coin A) = 1 - [ P (Head/Coin A) ] = 1 - 1/4 = 3/4
- Prob (Head / Coin B) = 3/4
- Prob (Tail / Coin B) = 1 - [ P (Head/Coin B) ] = 1 - 3/4 = 1/4
Probability of getting head by Coin A : Prob (Coin A) & Prob (Head/CoinA) = 1/2 x 1/4 = 1/8
Probability of getting tail by Coin A : Prob (Coin A) & Prob (Tail/CoinA) = 1/2 x 3/4 = 3/8
Probability of getting head by Coin B : Prob (Coin B) & Prob (Head/CoinB) = 1/2 x 3/4 = 3/8
Probability of getting tail by Coin B : Prob (Coin B) & Prob (Head/CoinB) = 1/2 x 1/4 = 1/8
Probability 'The guess [head from coin B, tail from coin A] :
Prob (Coin A) & Prob (Tail/CoinA) or Prob (Coin B) & Prob (Head/CoinB)
= 3/8 + 3/8 = 3/4
Answer:
I think it is option C, 3-4x
Answer: (w² + 10)inches²
Step-by-step explanation:
Since the width of the rectangular blanket is given as w and the length of the blanket is 10inches greater than it's width, therefore the length will be:
= 10 + w.
Therefore,
length = 10 + w
width = w
Area = length × width
Area = (10 + w) × w
Area = 10w + w²
Therefore, the area of the blanket will be (w² + 10)inches².
