Answer: 60 different numbers can be formed
Step-by-step explanation:
Note that we have 5 different digits, and we must select 3 of them. They should not be repeated
The order of selection is important in this case, because the number 532 is not the same as the number 235.
So we have a permutations problem, where we have a set of n elements and we want to choose r from them.
Then we define the permutacion as:
In this case note that n=5 because there are 5 elements in the set.
r = 3 because we combine the elements to form three-digit numbers
Then:
Answer:
50%.
Step-by-step explanation:
Given that a math class contains 40 students, and there are 18 females (two of whom speak Spanish) and 22 males (two of whom speak Spanish), in order to know the percent of Spanish speaking students that are male with respect to the total Spanish-speaking students, the following calculation has to be made:
2 + 2 = 4
2 / 4 = 0.5
Therefore, the percentage of Spanish speaking students that are male is 50%.
Answer:
No, it is not a function.
Step-by-step explanation:
A function graph are graphs where the lines do not connect. Since the shape is a circle, many lines in the graph are connecting.
Answer:
no idea too hard but try math way
Step-by-step explanation:
Answer:
400 degrees
Step-by-step explanation:
Step 1 : To convert radians to degrees, multiply the given radian by 180/pi
7pi/3 x 180/pi
Step 2 : Cancel pi
7/3 x 180
= 420 degrees
Step 3 : Round it to nearest 100
Since 20 is closer to 400 than 500 therefore it will be rounded off to
400 degrees
