Answer:
40, 60, 80
Step-by-step explanation:
The sum of angles in all triangles is 180 degrees (assuming you are talking about Euclidean geometry). If 2:3:4 is the ratio then
2x + 3x + 4x = 180
9x = 180
x = 20
Now that we now what x is, we can find the respective angles by plugging the value of x in. The angles are 40, 60, and 80 respectively.
Answer:
Which of the choices below best describes how to measure the center of these data?
Both centers are best described by the mean
Step-by-step explanation:
Mean describes the central number of a discrete data
it has a formula;
mean= sum of terms/no of terms
Given
Answer
The graph touches the x-axis at -6
Hence x = -6 is the zero of the graph.
Answer:
The answer would be false.
Step-by-step explanation:
Not all angles are going to add up to be greater than 90 degrees. say you have two angles that both measure to be 30 degrees, when they are added, they do not equal 90. Hope this helped!
Given that there are 12 persons, the first choice may be in 12 different ways, the second choice may be in 11 different ways, ther third in 10 different ways, the fourth in 9 different ways and the fith in 8 different ways, for a total of:
12x11x10x9x8 different combinations.
Now you have to take in account that 5x4x3x2 are repetitions. So you have to divide the previos counting by 5x4x3x2.
(12x11x10x9x8)/(5x4x3x2) = 792 different subcommittees.
Also, you can use the formula for combinations: C(m,n) = m! / (n! (m-n)!)
C (12, 5) = 12! / (5!) (12-5)! = [12x11x10x9x8x7!] / [5! 7!] = [12x11x10x9x8]/[5x4x3x2] = 792
