Step-by-step explanation:
line s || line t
r is the transversal,
Therefore,
(7x-2)°= (6x+18)° {exterior alternate angles}
7x-6x=18+2
x=20°
r is also a straight line,
therefore,
7x-2+angle1=180° (straight angle)
7x-2+ angle1=180°
7(20)-2+ angle 1= 180°
140°-2+ angle 1= 180°
angle 1= (180-140+2 )°= 42°
angle 1= 42°
2(3x-1) >=4x-6
6x-2>=4x-6
6x-4x>= -6+2
2x>=-4
x>=-2
You can see after simplification, the valve of x can be any number greater than or equal to -2. i.e -5 and -3 can not be in the solution set. the first choice can be dismissed, the fact the variable O could be any number that may not satisfy the solution. Therefore 0-1 is the answer, any thing between 0 & 1 including 0 and one satisfy the solution set
Answer:
$69.98
Step-by-step explanation:
$39.99 + $29.99 = $69.98
The answer is the angles are neither complementary nor supplementary, because complementary is to add up to 90° and supplementary is to add up to 180°, and these angles add up to 169°. I hope this helps!
Answer:
42% of the students prefer a concert over a movie.
A greater ratio of 11th graders prefer a concert to a movie.
The difference in the percent of students who prefer a movie over a concert is16%.
Step-by-step explanation:
10th 11th 12th total
movie .18 .16 .24 .58
concert .15 .18 .09 .42
total .33 .34 .33 1
The marginal relative frequency for 10th graders is 0.18. This is an incomplete statement
The marginal frequency is a number not a percent
42% of the students prefer a concert over a movie. 42% preferred a convert to the 58% who preferred a movie. True
A greater ratio of 11th graders prefer a concert to a movie. 18/100 concert to 16/100 for the movie for 11th graders
18:16 This is true
More 12th graders were surveyed than any other grade level.
There were more 11th graders surveyed (34%) to (33%) for 12 graders False
The difference in the percent of students who prefer a movie over a concert is16%. True
