A (central angle) has the same measure as its arc.
Let
P(h)= probability of selecting heart = 13/52= 1/4
similarly
P(s)= probability of selecting spade =1/4
P(c)= probability of selecting club =1/4
P(d)= probability of selecting diamond =1/4
a)
P(h or s)= P(h)+P(s)= 1/4+1/4=2/4=1/2=0.5
b)
P(h or s or c)=P(h)+P(s)+P(c)=1/4+1/4+1/4=3/4=0.75
c)
P(2 or a diamond)=n(2heart, 2spade,2club,13 diamonds)/total number of cards
=(1+1+1+13)/52=16/52=4/13=0.3
or we could solve it as follows:
P(2 or a diamond)=P(2)+P(diamond)-P(2diamond)=4/52 + 13/52 + 1/52 = (4+13-1)/52=16/52=0.3
$13, 666.67
because you would do 820 divided by 0.06 and you get 13,666.6667 which you round to 13,666.67
Answer:
x = 
Step-by-step explanation:
5x + 2(x + 1) = 4
5x + 2x + 2 = 4 (here we got rid of the parenthesis)
7x + 2 = 4 (here we summed both of our x values)
7x = 4 - 2 (here we took #2 to the other side of the equation)
7x = 2 (we subtracted 4 - 2)
x = 2 / 7
x =

Let x = the shorter piece and Let y = the longer piece.
(3/4)x = 120
x = 120 / (3/4)
x = 120 * (4/3 = 480/3) = 160 feet
y = 160 + 12
