Answer:

a) 2/25 b)1/5 c)As the number of spins increases, we expect the experimental and theoretical probabilities to become farther apart.

Step-by-step explanation:

a) Experimental probability is the fraction of the outcome of the experiment. experiment had 2 black and 25 total, so the probability would be 2/25.

b) Theoretical probability is when you look at the spinner's probability, our assumption. The spinner had 2 black and 10 total sections, therefore 2/10 or ⅕.

c) A and b prove this theory. The more me spin it, the futhur away the probability gets.

Mia is 7.02576 × 10^6 minutes old. Convert her age to more appropriate units using years, months, and days. Assume a year has 36
Naya [18.7K]

Answer:

Number of days = 4879 days

Number of months = 162.63 months

Number of years = 13.37 years

Step-by-step explanation:

Given

Mia's age (in minutes) = 7.02576 * 10^6

Required

Calculate age in years, months and days.

For ease of work, we'll start by converting to days.

First, it should be noted that there are 24 hours in one day

And there are 60 minutes in an hour.

This means that there are 24 * 60 minutes in a day

Number of minutes = 24 * 60 minutes

Number of minutes = 1,440 minutes

So, if number of minutes in a day is 1,440

Number of days in 7.02576 * 10^6 minutes is calculated as follows

Number of days = \frac{7.02576 * 10^6}{1440}

Number of days = 4879 days

Now, we can convert this to month and year, easily.

From the question, it should be assumed that there are 30 days in a month.

If 1 month = 30 days

Then, there are \frac{4879}{30} months in 4879 days

Number of months = \frac{4879}{30}

Number of months = 162.63 months

Converting to year

From the question, it should be assumed that there are 365 days in a month.

If 1 year = 365 days

Then, there are \frac{4879}{365} years in 4879 days

Number of years= \frac{4879}{365}

Number of years = 13.37 years

If S is the midpoint of RT, RS=5x+17, and ST=8x-31, find RS
Fantom [35]
A midpoint divides a line into two equal parts so
5x+17=8x-31
17=3x-31
3x=48
x=16

RS=5x(16)+17
80+17=97
RS=97

Softa [21]

Answer:

C. {(2,4) (3,4) (4,4) (5,4) (6,4)} is a function.

Step-by-step explanation:

Since there is one value of  y  for every value of  x  in  {(2,4) (3,4) (4,4) (5,4) (6,4)}, this relation is a function.
