Answer:
0.13%
Step-by-step explanation:
Mean, u = 17.4%
standard deviation, sd = 27.5%
We are looking for the probability that the money will double in value. Therefore we are looking for the value of x = 100% (meaning the value is 100% more that the previous year)
Find the value of z-score
z = (x-u)/sd
= (100 - 17.4) / 27.5 = 3.003
Find the z score using the z-table
From z-table at P(z<3.003) = 0.9987
So, for the probability that it the money will be double is
P (Z>2.8982) = 1 - P(z<2.8982)
= 1- 0.9987
= 0.0013 = 0.13%
Answer:
Step-by-step explanation:
we know that
There are 
people in Springfield. 
of the population of Springfield are under the age of 
so
To calculate how many people are under in Springfield
Multiply by
<span>To multiply two radicals together, we can simply multiply both the values inside the radicals together and put that in a radical.
So for 5*sqrt(45b) * 6*sqrt(48b), we get 30*sqrt(45b*48b) = 30*sqrt(2160b^2). This value can be simplified further by taking out b^2 and 12^2 from the radical giving us the answer 360b*sqrt(15).</span>
Answer:
The triangle is an obtuse scalene triangle
Step-by-step explanation:
we know that
if 
--------> is a right triangle
if 
--------> is an obtuse triangle
if 
--------> is an acute triangle
where
c is the greater side
we have
so
so
-------> is an obtuse triangle
Remember that
The given triangle has three different length side
so
Is a scalene triangle
therefore
The triangle is an obtuse scalene triangle
Answer:
For this case, the first thing we must do is define variables:
x: number of hammers
y: number of wrenches
We write the system of inequations:
10x + 6y <= 120
x + y> = 14
Step-by-step explanation:
