Answer:

p(A) = 0.55

p(b) = 0.45

Step-by-step explanation:

Experimental probability = \frac{Number of favorable outcomes}{Total number of outcomes}

total students = 55 + 45   ⇒ 100

let A be the probability that students brought lunch from house = \frac{55}{100} ⇒ 0.55

let B be the probability that students order school lunch = \frac{45}{100} ⇒ 0.45

Mirror and the three friends each had three over for food of they need it to have 5 feet of rope altogether. Do they have enough
BabaBlast [244]

Answer:

Do they have enough?

Nope, they don't have enough.

Step-by-step explanation:

They would not have enough because 3/4 times 4 would not equal 5...it would equal 3. Mario and his 3 friends each have 3/4 foot of rope. They needed 5 feet of rope altogether. Do they have enough rope? They would need 2 more feet of rope to complete the 5 feet. But they do not have enough feet of rope to make 5 feet.

Hope it helped u if yes mark me BRAINLIEST!

ram is half his fathers age now. ten years ago he was one third his fathers age then what are their present ages
NeX [460]

x   -  Ram's age now

Ram is half his father's age now, so his father's age is two times Ram's age:

2x  - Ram's father age now

x - 10   -  Ram's age ten years ago

2x - 10    - Ram's father age ten years ago

ten years ago he was one third his father's age so his father's age was three times Ram's age:

2x - 10 = 3•(x - 10)

2x - 10 = 3x - 30

-10 + 30 = 3x - 2x

20 = x

2x = 2•20 = 40

Answer:

<u>Ram is 20 years old now, Ram's father is 40 years old now.</u>
