Since we are asked to compute the probability of two event with "or"
statement, then we will add the probabilities like this:
Denote A the first event and B the second event:
A="Get an even number":
B="Get section B":
Conclusion:
The probability is 5/6
Answer:
D The value of the 2 in 12.5 is 1,000 times the value of the 2 in 0.912
Step-by-step explanation:
The value of a digit in a number can be found by setting the other digits to zero.
The value of 2 in 12.5 is 2.
The value of 2 in 0.912 is 0.002.
The ratio of values is 2.000/0.002 = 2000/2 = 1000.
The value of 2 in 12.5 is 1000 times the value of 2 in 0.912.
Answer:
306 km
Step-by-step explanation:
put both of them to equal in ratio form so now
85 / (7/6) = x / (21/5)
85 * (21/5) = 7/6x
357 = 7/6x
x = 306 km
Answer:
let the number be x, so that the two numbers are x and x - 32 The first number is x = 62.
The second number is x - 32 = 62 - 32 = 30.
Step-by-step explanation:
x + x - 32 = 92
or, 2x = 92 + 32
or, 2x = 124
or, x = 124/2 = 62
We have that
tan x=5
we know that
tan x =sin x/ cos x
sin x/ cos x=5------> squaring-----> sin² x/cos² x=25
remember that
sin² x+cos² x=1-----> cos² x=1-sin² x
substitute
sin² x/[1-sin² x]=25
sin² x=25-25*sin² x
26*sin² x=25
sin² x=25/26
sin x=5/√26
cos² x=1-(5/√26)²----> 1-(25/26)----> 1/26
cos x=1/√26
the answers are
sin x=5/√26
cos x=1/√26
