Step-by-step explanation:
the probability is always the number of desired cases over the number of all possible cases.
in our situation we have 15 cards.
that is the total possible cases when a random card is chosen.
how many desired cases do we have ?
a number NOT a multiple of 5.
how many are there ?
it is easier to say how many numbers there are being a multiple of 5 : 5, 10, 15
so, 3 numbers out of the 15 are multiple of 5.
that means
15 - 3 = 12 numbers of the 15 are NOT multiples of 5.
so, the probability to draw a card that is not a multiple of 5 is
12/15 = 4/5 = 0.8
the information about event B and even numbers is irrelevant for the question.
Exponential functions are in the form
, where <em>a</em> is the initial value, <em>b</em> is the growth rate (percent increase) + 1, and <em>x</em> is the number of time periods. Our initial value is 100, and we're given the growth rate + 1 (tripling is the same as increasing by 200%; 200%=2.0; 2.0+1=3). Therefore our function is
.
Answer:
the answer is the last one
Step-by-step explanation:
Answer:
-3/5
Step-by-step explanation:
First, make the mixed fraction into an improper fraction:
-1 2/5 = -(5/5 + 2/5) = -(7/5)
Note that two negatives = one positive:
- (-4/5) = + 4/5
Combine the terms. Subtract the numerators:
-(7/5) + (4/5) = (-7 + 4)/5 = -3/5
-3/5 is your answer.

Hello,
This is simple :)
<span>First divide:
How many times does 16 go into 7? : 0
7 GOES into 16, 0 times, now we have ; 0.
Next, multiply 16(0):0
Now, subtract 7-0
=7
Bring 0 down... so now we have 70... how many times can you divide 16 into 70? : about 4 times.
Now we have: 0.4
Multiple 16 by 4
= 64 : SUBTRACT 64 from 70
=60
Bring Down: 0; this gives us 60.
Divide:
How many times can 16 go into 60? : About 7 times
No we have : 0.437..
Bring down 0; gives us 600: how many times can 16 go into 600?: About 5 times.
Now, we have 0.4375.
Thus, 7/16 = 0.4375.
