There are 70 students in the school band. 40% of them are sixth graders, 20% are seventh graders, and the rest are eighth grader
Anon25 [30]

Answer:

The number of students in the school band = 70

40% of students in the school band are sixth graders.

20% of students in the school band are seventh graders.

We have to find the number of band members that are sixth graders.

The number of sixth graders in school band are:

40\% of 70

0.40 \times 70

28

Therefore, there are 28 band members that are sixth graders.

What is the probability that a group of five friends all have different birthdays? Show all of your work for full credit.
patriot [66]

Answer: 0.98630136986

Step-by-step explanation:

There are 365 possible birthdays. The key to assigning the probability is to think in terms of complements: “Two (or more) people share a birthday” is the complement of “All people in the group have different birthdays.” Each probability is 1 minus the other. What is the probability that any two people have different birthdays? The first person could have any birthday (p = 365÷365 = 1), and the second person could then have any of the other 364 birthdays (p = 364÷365). Multiply those two and you have about 0.9973 as the probability that any two people have different birthdays, or 1−0.9973 = 0.0027 as the probability that they have the same birthday. If you have a group of five, it would mean your equation would have to be (p=360÷365)

At the age of 22, Vicki opened an IRA. At the beginning of each year, she deposits $1100 into her IRA, which earns 9% annual int
jeyben [28]

Answer:

$51,557.00

Step-by-step explanation:

1100 times 9% = 99 a year

99 times 43 = 4257

1100 times 43 =47,300

then you add 47,300 + 4257 = 51,557

you take your total that she put into the ira and multiply it by 9%

then you multiply that total by the number of years before she retires which is 43

so 99 times 43 = 4257

then you will multiply how much she put in the ira at the beginning of the year which is 1100 by the 43 years before she retires which is 47,300

then you add your totals together

4257 + 47,300 = 51,557
