Answer:

6/36 or 1/6

Step-by-step explanation:

To find the probability of rolling a number greater than 4, then rolling an odd number, you must multiply the probability of rolling numbers greater than 4 by the probability of rolling an odd number. In numbers 1-6, there are two number greater than 4: 5 and 6. The probability of an event is the specific factor over the total amount of results or objects. The probability of rolling a number higher than 4 is 2/6, or 1/3. In numbers 1-6, there are 3 odd numbers: 1, 3, and 5. The probability of rolling an odd number is 3/6, or 1/2. 3/6 times 2/6 is 6/36, and when simplified, it becomes 1/6.

Two boys are running track. They decide to start in the northwest corner and go opposite directions around the rectangular track

Mariulka [41]

= 187.3 yards

Step-by-step explanation:

The set-up will represent a triangle whereby the :

Width = Height = 150 yards
Diagonal = Hypotenuse = 240 yards
Length = Base = ?

${a}^{2} = {c}^{2} - {b}^{2} \\ {a}^{2} = {240}^{2} - {150}^{2} \\ {a}^{2} = 57600 - 22500 \\ \sqrt{ {a}^{2} } = \sqrt{35100} \\ a = 187.3yards \: (rounded \: off \: to \: 1dp)$

This is used for the next few questions: The rating for the new scary movie has a scale of 0 to 10. The average response was tha

Pie

Answer:

The percentage that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8) = 83.9≅ 84 percentage

Step-by-step explanation:

Step(i):-

Mean of the Population = 8.3 points

Standard deviation of the Population = 0.5 points

Let 'X' be the random variable in normal distribution

Let X = 6.8

$Z = \frac{x-mean}{S.D} = \frac{6.8-8.3}{0.5} = -3$

Let X = 8.8

$Z = \frac{x-mean}{S.D} = \frac{8.8-8.3}{0.5} = 1$

The probability that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8) = P(-3≤Z≤1)

= P(Z≤1)- P(Z≤-3)

= 0.5 + A(1) - ( 0.5 -A(-3))

= A(1) + A(3) (∵A(-3)=A(3)

= 0.3413 +0.4986 (∵ From Normal table)

= 0.8399

Conclusion:-

The percentage that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8) = 83.9≅ 84 percentage
