Answer:
D
Step-by-step explanation
Since we are reflecting across the x axis, all of the y coordinates will remain the same. You find the distance away from the x = 4, double it, and add that value to x. So,
X' is now (8,3)
Y' is now (6,0)
Z' is now (4,2) because its x was 0, and anything * 0 = 0 so it does not move.
Answer:
x=31.25%
Step-by-step explanation:
set up a proportion as 15/48=x/100 and solve.
The correct is 40 hope I helped
Procedure:
1) calculate the number of diferent teams of four members that can be formed (with the ten persons)
2) calculate the number of teams tha meet the specification (two girls and two boys)
3) Divide the positive events by the total number of events: this is the result of 2) by the result in 1)
Solution
1) the number of teams of four members that can be formed are:
10*9*8*7 / (4*3*2*1) = 210
2) Number of different teams with 2 boys and 2 girls = ways of chosing 2 boys * ways of chosing 2 girls
Ways of chosing 2 boys = 6*5/2 = 15
Ways of chosing 2 girls = 4*3/2 = 6
Number of different teams with 2 boys and 2 girls = 15 * 6 = 90
3) probability of choosing one of the 90 teams formed by 2 boys and 2 girls:
90/210 = 3/7
Answer:
Arithmetic
Step-by-step explanation:
An arithmetic progression is characterised by the first term (a), number of terms (n) and common difference (d).
