Answer:
b. 0.216
Step-by-step explanation:
For each student, there are only two possible outcomes. Either they have a job, or they do not. The probability of a student having a job is independent of other students. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
60% of the students at a large university have a job
This means that 
If three of these students are randomly selected what is the probability all three have jobs?
This is 
when 
. So
So the correct answer is:
b. 0.216
Here is the formula for determining the volume of rectangular prism
From the question above, we know that
l = 14 yd
w = 5 yd
h = 8 yd
plug in the numbers into the formula
V = l × w × h
V = 14 × 5 × 8
V = 560
The volume is 560 yd³
Answer:
(a) (f+g)(x) = √(2x) +x²
(b) (f-g)(x) = √(2x) -x²
(c) (f·g)(x) = x²√(2x)
(d) (f/g)(x) = (√(2x))/x²
Step-by-step explanation:
These are all about the meaning of the notation (f <operator> g)(x). When the operator is an arithmetic operation (addition, subtraction, multiplication, division), the notation means the same thing as ...
f(x) <operator> g(x)
__
(a) (f+g)(x) = f(x) + g(x)
(f+g)(x) = √(2x) +x²
__
(b) (f-g)(x) = f(x) -g(x)
(f-g)(x) = √(2x) -x²
__
(c) (f·g)(x) = f(x)·g(x)
(f·g)(x) = x²√(2x)
__
(d) (f/g)(x) = f(x)/g(x)
(f/g)(x) = (√(2x))/x²
Answer:
$53.00
Explanation :
20% would be $8.80
$8.80+$44.00=$52.80
$52.80 rounded to the nearest dollar would be $53.00
Answer:
Brownies
18
54
270
Cooldies
16
32
96
384
Step-by-step explanation:
Brownies
simply multiply the 18 by 3 we get 54 and if we multiply 54 by 5 we get 270.
we multiply it by 5 because in series it skip 1 number to multiply next.
Cooldies
first we multiply 16 by 2 we get 32.
next we multiply 32 by 3 we get 96.
and next we multiply 96 by 4 we get 384.
Simply increment in multiplication.
