Answer:
x = 50
Step-by-step explanation:
The angles 70, 60, and y are supplementary, meaning that the sum of them is 180. Therefore,
70 + 60 + y = 180 and
y = 50
That means that x = 50 as well, since vertical angles are congruent
Answer:
x = 95
Step-by-step explanation:
(2x - 60)° = (x + 35)° (corresponding angles are congruent)
2x - 60 = x + 35
2x - 60 - x = x + 35 - x
x - 60 = 35
x - 60 + 60 = 35 + 60
x = 95
Answer: $2880
Step-by-step explanation:
I = P • r • t
I = 12000 • 0.06 • 1460/365 (I used 1340/365 because there are 365 days in a year. 4 years = 1460)
I = 2880
Answer:
a) 19 students
b) the mean 3 9/19
the median 3
the mode 3
c) the range 6
Step-by-step explanation:
The data set shows that
0 points gets 1 student,
1 point gets 1 student,
2 points get 2 students,
3 points get 6 students,
4 points get 4 students,
5 points get 3 students and
6 points get 2 students.
a) There are 1+1+2+6+4+3+2=19 students.
b) The mean is

The average score is 3 9/19 points.
The median is 10th term in the data set - 3 points (means the middle score in the data set)
The mode is 3 points (means most happened score)
c) The range of the data is 6-0=6 points.
