The period of a sinusoid
is
, so any range such that
will give two complete periods.
Answer:
a) 62
b) 31/45
Step-by-step explanation:
a) The table tells you there are 42 males, and 20 more females that study biology.
42 +20 = 62 . . . are male or study biology or both
__
b) Of the total of 90 people, 62 are male or study biology (or both). The probability that any person is in that category is ...
62/90 = 31/45 = P(male or biology)
First you can divide 44 into 15, which is two with a remainder of 14 so that means the mixed number would be 2 and 14/15

Answer:
Rational
Step-by-step explanation:
A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number.
Answer:
1/3 is the only fraction here that is greater than 3/10.
Step-by-step explanation:
Convert these to decimals first, which can make it easier.
1/3 as a decimal is 0.33333333333333333333333333... which is greater than 0.3, which is 3/10.
3/11 as a decimal is 0.27272727272727.... which is LESS than 0.3, which is 3/10.
4/15 as a decimal is 0.26666666666666666666666666666666, which is less than 0.3, which is 3/10.
29/100 as a decimal is 0.29, which is less than 0.3, which is 3/10.
So the answer is 1/3.
