Answer:
Distinct ways in which they all can form the teams for the class = n(n-1)
Step-by-step explanation:
Total numbers of students = n (even number)
Number of student in each team = 2
Number of distinct ways are there to form the teams for the class:
where = n = number of elements = n
k = number of elements choose = 2
Answer:
1.) 65 2.)73 acute 3.)Obtuse, scalene
Answer:
Equivalent ratios (which are, in effect, equivalent fractions) are two ratios that express the same relationship between numbers. We can create equivalent ratios by multiplying or dividing both the numerator and denominator of a given ratio by the same number. Two ratios that have the same value are called equivalent ratios. To find an equivalent ratio, multiply or divide both quantities by the same number. It is the same process as finding equivalent fractions.
Answer:
16.7%
Step-by-step explanation:
The first thing is to mention that they are two independent events, therefore the final probability is the multiplication of the two.
First event, select shirt. In total there are 4 and you must choose one of them, therefore the probability is:
1/4
Second event, select the pants. In total there are 3 and you must choose one of them, but there are two blue types, therefore any of the two is worth what means that the probability is:
2/3
The final probability:
P = 1/4 * 2/3
P = 0.167
Which means that the probability of choosing a white shirt and a blue pant (light or dark) is 16.7%
13: C
14: B
For 13, plug the 9 into the equation where b is, you get 3 • 9 = 27 (the 27 is s)
For 14, ordered pairs go horizontal distance first then vertical distance
