What is the difference between a 30° angle and a -30° angle?

ipn [44]

Answer:

See below

Step-by-step explanation:

A 30° angle is measured 30° counterclockwise while a -30° angle is measured 30° clockwise. Therefore, you can say -30°=360-30°=330° because 30° is a reference angle located in Quadrant IV.

In a certain Algebra 2 class of 30 students, 18 of them play basketball and 9 of them

marshall27 [118]

Probability that a student will play both is 7/30

Step-by-step explanation:

Total students = 30

No. of students who play basketball = 18

Probability that a student will play basketball = 18/30

= 3/5

No. of students who play baseball = 9

Probability that a student will play baseball = 9/30

= 3/10

No. of students who play neither sport = 10

Probability that a student will play neither sport = 10/30

= 1/3

To find :

Probability that a student will play both = p(student will play both)

No.of students who play sport = 30 - 10

= 20

Out of 20 students 18 play basketball and 9 play baseball.

So, some students play both the sports.

No. of students who play both sports = 18 + 9 - 20

= 7

p(student will play both) = 7/30

Probability that a student will play both is 7/30

Write an equation of a line in slope-intercept form that passes through (-3,5) and is parallel to y = -6x +1.

katrin2010 [14]

Answer:

a) The equation of the Parallel line to the given straight line is

6 x + y + 13 =0

b) Slope - intercept form

y = - 6 x - 13

c) The intercept - form

$\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1$

x - intercept = $\frac{-13}{6}$

y - intercept = - 13

Step-by-step explanation:

Step(i):-

Given the equation of the straight line

y = -6x +1

6 x + y - 1 = 0

The equation of the Parallel line to the given straight line is

6x + y + k=0 and it passes through the point (-3, 5 )

⇒ 6 (-3 ) + 5 + k =0

⇒ - 18 + 5 + k=0

⇒ -13 + k = 0

⇒ k = 13

The equation of the Parallel line to the given straight line is

6 x + y + 13 =0

Step(ii):-

Slope - intercept form

y = m x + C

y = - 6 x - 13

Step(iii):-

Intercept - form

6 x + y + 13 =0

6 x + y = - 13

$\frac{6x + y}{-13} = \frac{-13}{-13}$

$\frac{6x}{-13} + \frac{y}{-13} = 1$

$\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1$

The intercept - form

$\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1$

x - intercept = $\frac{-13}{6}$

y - intercept = - 13
