The answer is 10/36 or 27.77%
here’s the working out
Answer:
Rounding to the nearest tenth and rounding to the nearest one hundredth.
Step-by-step explanation:
round all up or down then line up and add
12.568= 13
11.426= 11
12.324= 12
11.981= 12
12.601= 13
add the totals then you see
60.83 sames as 61
Answer:
The value of x is 10
Step-by-step explanation:
We can use a system of equations to solve this.
Cups of 25% bleach solution used = x
Cups of 1-% bleach solution used = 5
Cups of solution we get = y
The first equation becomes:
x + 5 = y
Using the decimal forms of each percentage solution
25% solution for x cups = 0.25x
10% solution for 5 cups = 0.1(5)
20% solution for y cups = 0.2 y
The second equation becomes:
0.25x + 0.1(5) = 0.2y
So the system of equations is:
x + 5 = y
0.25x + 0.1(5) = 0.2y
Solve both equations simultaneously to find the values of x and y:
x = 10 cups
y = 15 cups
Answer:
- a. 0.1647;
- b. 0.7153;
- c. 0.4453.
Step-by-step explanation:
By definition, if two event
and
are independent, then
. (
is the probability that the outcome of both event
and event
are true.)
<h3>a.</h3>
Since the outcome of these two events are independent,
.
<h3>b.</h3>
The logic not operator
or the prime superscript
denotes that an event does not happen.
.
.
Since the two events
and
,
and
are also independent. Probability that neither professor got funded:
.
Probability that at least one professor got funded- in other words, it is not true that neither professor got funded:
.
<h3>c.</h3>
Similarly, since the two events
and
,
and
are also independent. Probability that Jane but not Joe got funded:
.
