Answer:
12
Step-by-step explanation:
The sum of the exterior and interior angles = 180°
let x be the measure of the exterior angle then interior angle is 5x and
5x + x = 180
6x = 180 ( divide both sides by 6 )
x = 30
The sum of the exterior angles of a polygon = 360°, thus
number of sides = 
= 12
Answer:
H0: μc ≤ μs Ha :μc > μs
Step-by-step explanation:
The null and alternate hypotheses can be stated as
H0: μc ≤ μs Ha :μc > μs one tailed test
Where
μc = Mean of college students watching movies in a month
μs = Mean of school students watching movies in a month
For one tailed test of α =0.05 the value of Z= ± 1.645
The critical region will be Z > ± 1.645
It is of importance to note that by rejecting the null hypothesis and accepting the alternate hypothesis we are automatically rejecting all values of mean that are greater than 7.1
Answer:
For the given question,the equation of the asked line would be same as that of the line parallel to it but the only difference would be in the constant part.
Step-by-step explanation:
the equtions of the lines (variable parts) would be the same but the constant part will be different according to the point known on the particular line.
Answer:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Step-by-step explanation:
Answer:
angle 5 is 61°
angle 7 is 61°
Step-by-step explanation:
1. angle 7 + angle 8 = 90° Because they are complementary angles
2. Because of point 1 above, angle 5 + angle 6 = 90°
3. since given angle 6 = 29°
so, angle 5 = 90° - 29° = 61°
4. since given angle 5 = angle 8
so, angle 8 = 61°
5. from point 1 above,
angle 7 + 61° = 90°
so angle 7 = 29°
