Answer:
π
Step-by-step explanation:
The standard form of the sine function is
y = a sin(bx + c)
where a is the amplitude, period = 
and
phase shift = - 
here b = 
, c = - 
phase shift = - 
= × 2 = π

Answer:
y = 7, x = 7
Step-by-step explanation:
11y + 13 = 90
11y = (90 - 13)
11y = 77
y = 7
2x + 6 = 20 (because 20 is half of 40)
2x = (20 - 6)
2x = 14
x=7
Answer:
P(compact cars) = 4/25 or .16
Step-by-step explanation:
<em>We know that there are </em><em>13 trucks, 8 vans, and 4 compact cars.</em>
<em />
<em>Let </em><em>P </em><em>denotes the probability of an event</em>
<em />
<em>Now we are asked to find the probability of compact cars</em>
<em />
<em>Number of favorable events = number of compact cars = 4</em>
<em />
<em>total number of outcomes </em><em>= 13+8+4 = 25</em>
<em>hence, P(compact cars) = number of favorable events/total outcomes</em>
<em> =4/25 or .16</em>
