Answer:
21°, 84°, 75° are the angles
Step-by-step explanation:
Total angle in a triangle is 180.
x + 4x + (5x - 30) = 180
10x - 30 = 180
10x = 210
x = 21°
Angles are:
A: 21°
B: 4(21) = 84°
C: 5(21) - 30 = 75°
Answer: B. Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.
Step-by-step explanation:
Given the following list of data:
83 45 80 53 46 24 79 34 55 10 44
Range :
(Highest - Lowest) value
83 - 10 = 73
Sample Variance :
[Summation of (x - mean)^2] / number of observation - 1
Mean = (83+45+80+53+46+24+79+34+55+10+44) / 11
= 553 / 11 = 50.3
Check attached picture for computation of variance and standard deviation.
In football, jersey numbers do not imply any statistical relevance or importance
Answer: No, Mai needs to solve the problem.
Step-by-step explanation:
2x+2=x+1 - subtract 2 from both sides
2x=x-1 - subtract x from both sides
x= -1 - solution
Answer: $50
Step-by-step explanation:
Int = 2000*0.03*(10/12) = $50
It is going to be 125 I hope you got the answer right
