Answer:
See below
Step-by-step explanation:
a)
P(A or Black) = (73 + 27)/127 = 100/127 = 0.7874015748
b)
P(Red) = red/total = 39/127 = 0.30708661417
c)
P(Manufacturer B and Red) = (B and red)/total = 10/ 127 = 0.0787401575
d)
P(Manufacturer B or Red) = (B or red)/total = (54 + 29)/127 = 0.65354330708
Hi!
Let's write some equations to solve this.
h = hamburgers
c = cheeseburgers
h + c = 758
h + 58 = c
Let's put the value of c into the first equation.
h + h + 58 = 758
Simplify
2h + 58 = 758
Subtract 58 from both sides
2h + 58 - 58 = 758 - 58
2h = 700
Divide by 2 on both sides
2h/2 = 700/2
h = 350
350 hamburgers were sold on Sunday
Let's check our answer by putting the value of h into both of our original equations.
350 + c = 758
350 + 58 = c
Solve
350 + 58 = 408
c = 408
350 + 408 = 758
Our answer is correct.
Hope this helps! :)
23 units sure does hope this helps
It would be 0 because starting from -5, it would then be -10, -5, 0, -5, 0.
Answer:
tan x = 3/4.
Step-by-step explanation:
We know sin means 
in a right triangle. This means that the Hypotenuse= 5, and the Opposite side= 3.
Using Pythagorean theorem, we can determine that the 'Adjacent' side= 4.
The formula for 'tan' is 
. If we plug in our values, we get:
tan x = 3/4.
