What is that round white thing that Catholic Priests give to people?
My friend who is Catholic took me to her church and at the end of the service we lined up to get the little round white piece of bread given by the priest. When it was my turn I asked the priest if they had any salt to go along with it and he got mad and so did the other people behind me. Weird!!!
A group consists of 4 girls and 7 boys. In how many ways can a team of 5 members be selected if the team has at least one boy and one girl?
We have 4 favorable cases: (1 boy, 4 girls), (2 boys, 3 girls), (3 boys, 2 girls), (4 boys, 1 girl).Total number of favorable cases: 7c1*4c4 + 7c2*4c3 + 7c3*4c2 + 7c4*4c17*1 +21*4 + 35*6 + 35*4 = 7+84+210+140 = 441This can also be done by subtracting the case of selecting all 5 boys from total number of selections.That is, 11c5 - 7c5 = 441
What kind of music do you like and why?
There is so much great music from around the world and from past centuries. Sometimes it sounds and is composed so differently that it takes a bit of time to get use to it.I love Icelandic and Irish folk music as well as Medieval and Renaissance music when it’s properly played on instruments that are as authentic as possible. I also love intricate polyphony, especially the keyboard music of J.S. Bach and Scarlatti.I just recently started listening to American blues and bluegrass music, some jazz and old rock music from the 60s, I find the music of the middle east fascinating but I don’t know enough about it to really appreciate it yet. My ears just aren’t use to the many semi tones.It is pretty amazing how humans could come up with so many different types of stunningly creative and beautiful music.
In a class of 50 students, 40% are girls. What is the number of boys in the class?
Do the math.In a class of 50 students, 40% are girls. What is the number of boys in the class?First off, let's find out the number of girls in the class by using this technique of math.Percentage of girls : 40%Number of students in the class: 50Now, divide the number of students by 100, and multiply it by the percentage of girls in the class. That is,(50÷100) x 40= ½ x 40.The answer is 20.So, the number of boys : Total number of students - Number of girls.That is: 50 - 20 = 30.So, the number of boys in the class is 30.
