Answer:
The probability is 0.0955
Step-by-step explanation:
The number of ways in which we can select k elements from n elements in which the order is not important is given by combinations and it is calculated as:
So, the total number of ways in which we can select 4 students from the 35 in the statistics class are:
From this, the number of ways in which there are exactly one freshman, one sophomore, one junior and one senior are calculated as:
5C1 * 10C1 * 10C1 * 10C1 = 5,000
Because:
- 5C1 are the number of ways in which we can select one freshman from the 5 that are in the statistics class,
- the first 10C1 are the number of ways in which we can select one sophomore from the 10 that are in the statistics class
- the second 10C1 are the number of ways in which we can select one Junior student from the 10 that are in the statistics class
- the third 10C1 are the number of ways in which we can select one senior student from the 10 that are in the statistics class.
So, the probability is calculated as a division between the number of ways in which there are exactly one freshman, one sophomore, one junior and one senior and the total number of ways in which we can select 4 students from the 35 in the statistics class. This is:
Answer:An integer is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not. ( means Whole in Latin ) please give brainliest if possible
No because if she has 30 grams of flower, 16 are being used by the chowder. She would only have 14 grams of flour left and she would need 15 for 3 pots of potato.
2 3/5 = 1 5/6 + x
x = 2 3/5 - 1 5/6 = 23/30 hours he spent on oral competition
Answer:
Yes, she should.
Step-by-step explanation:
5% may not seem like a lot. Lets say she deposits $20 per month. That's $240 a year. Lets also say you keep this for 6 years, you'll have $72 from interest. The more amount she puts in the more she'll gain.
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 240 × 0.05 × 6 = 72
I = $ 72.00
The simple interest accumulated
on a principal of $ 240.00
at a rate of 5% per year
for 6 years is $ 72.00.
