Answer:
x = 149
Step-by-step explanation:
Lines m and n are parallel lines as shown by the double arrows on each line.
The angles marked x and 149 deg are corresponding angles of parallel lines cut by a transversal.
<em>Postulate:</em>
<em>If parallel lines are cut by a transversal, then corresponding angles are congruent.</em>
According to the postulate above, since the angles marked 149 and x are corresponding angles, they are congruent.
x = 149
Answer:
Option C
Step-by-step explanation:
The chi square test of independence is used to determine if there is a significant association between two categorical variables from a population.
It tests the claim that the row and column variables are independent of each other.
The degrees of freedom for the chi-square are calculated using the following formula: df = (r-1) (c-1) where r is the number of rows and c is the number of columns.
Step-by-step explanation:
Total distance covered=distance covered by walking+distance covered by jogging
=6/7+4/5=30+28/35
=58/35miles
How much farther did you walk than jog
=6/7-4/5
=30-28/35
=2/35miles
Answer:
x = 36.9
Step-by-step explanation:
Use the sine function if you know the length of the opposite side and the hypotenuse. Plug your values into the equation: sine (x) = opposite ÷ hypotenuse. Say that the length of the opposite side is 6 and the length of the hypotenuse is 10. Divide 6 by 10, which is equal to 0.6. Now you know that sine (x) = 0.6 which is the same as x = sine^-1 (0.6).
Steps:
sin (x) = 6/10
sin(x) = 0.6
then we do sin^-1(0.6), which equals 36.869897645844 ° (degrees)
36.869897645844 ° (degrees) rounded to the nearest tenth is 36.9
so x = 36.9
