Maranda praticed a total of 52 hours in 4 weeks to prepare for a piano recital. If she practiced the same number of hours each w
RUDIKE [14]

The number of practice hours per week for Maranda's piano recital is 13 hours

Overall practice hours = 52 hours

Number of weeks of practice = 4 weeks

Since, the number of practice hours per week is the same ;

Number of hours practiced each week can be obtained by dividing the overall practice hours by the number of weeks of practice.

Number of practice hours per week = Overall practice hours ÷ Number of weeks of practice

Number of practice hours = (52 ÷ 4) = 13 hours

Therefore, Marana practiced for 13 hours each week.

Suppose we roll a fair six-sided die and sum the values obtained on each roll, stopping once our sum exceeds 285. Approximate th
OlgaM077 [116]

Answer:

1

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

Assuming we stop rolling the six-sided die once our sum is 290 ( exceeds 285)

Number of possible outcomes = 75, number of total outcomes = 290

Probability (75 rolls are needed to get this sum) = 75/290 = 0.259

Probability (more than 75 rolls are needed to get this sum) = 1 - 0.259 = 0.741

Probability (at least 75 rolls are needed to get this sum) means that either 75 rolls or more than 75 rolls are needed to get this sum = 0.259 + 0.741 = 1
