A jet left Paris at the same time as a
Anni [7]

Answer:

The speed of the jet is 410 mph.

Step-by-step explanation:

The jet and the passenger plane flew in opposite directions.  

Given that the passenger plane flew at a speed of 450 mph, then after 11 hours, the passenger plane will fly (450 × 11) = 4950 miles.

Again, given that after 11 hours the passenger plane and the jet are 9460 miles apart.

Therefore, in 11 hours the jet flew (9460 - 4950) = 4510 miles.

Hence, the speed of the jet is \frac{4510}{11} = 410 mph. (Answer)

Mr. Franklin asked each of his 30 students to select their favorite radio station.
Ostrovityanka [42]

Answer:

14

Step-by-step explanation:

We are given that

Total number of students who select their favorite radio station=30

Number of student who select their favorite radio station K=\frac{1}{3}\times 30=10

Number of student who select their favorite radio station L=\frac{1}{5}\times 30=6

We have to find that number of student who select station M.

Remaining students=30-(10+6)=30-16=14

Number of students who select their favorite radio station M=14

Hence, the number of students who select their favorite radio station M=14

Answer: 14

Helene claimed that the expected value when rolling a fair die was 3.5. Steve said that wasn't possible. He said that the expect
Nesterboy [21]

Answer:

Helene is right

Step-by-step explanation:

Mathematically, the expected values is defined as the sum of all the possible outcomes that an event can have times the probality of the respective outcome:

x = ∑ p *i,

where x is the expected value, i represents every outcome that can occur, and p is the probability of said outcome.

Now, for the case of a dice, the expected value would be:

x = 1 * \frac{1}{6} + 2 * \frac{1}{6} + 3 * \frac{1}{6} + 4 * \frac{1}{6} + 5* \frac{1}{6} + 6 * \frac{1}{6},

as every outcome has the same chance of happenning. Solving we get that:

x= \frac{1}{6} *(1 +2 +3 +4+5+6) = \frac{1}{6} * 21 = 3.5

Helene is right.
