the actual weights of bags of pet food are normally distributed about the mean of 50.0 lb with a standard deviation of 0.2 lb.
1. About what percentage of bags of pet food weigh between 49.8 lb and 50.2 lb?
2. About what percentage of bags weigh less than 49.8 lb?
3. In a group of 250 bags, what percentage of bags would you expect to weigh more than 50.4?
9514 1404 393
Answer:
68%16%2.5%Step-by-step explanation:
1. The empirical rule tells you 68% of the distribution is within 1 standard deviation of the mean. The mean is 50 and the standard deviation is 0.2, so this means 68% of the bags weigh between 49.8 and 50.2 lb.
__
2. The other 32% is evenly split above and below the central part of the distribution. That is, about 16% of the bags will weigh less than 49.8 lb.
__
3. The percentage is independent of the size of the group. The empirical rule tells you 95% lie within 2 standard deviations of the mean. The other 5% will be evenly split between those weighing more than 50.4 and those weighing less than 49.6 lb. About 2.5% of the bags will weigh more than 50.4 lb.
_____
Additional comment
It is useful to remember the empirical rule numbers, 68%, 95%, 99.7% for the portion of the distribution between ±1, 2, 3 standard deviations of the mean. They are useful for answering questions like this one. (They are only approximations, so if more accuracy is needed, a table or app should be used to find the accurate value.)
A software engineer creates a LAN game where an 8 digit code made up of 1,2,3,4,5,6,7,8 has to be decided on, universal code . There is a condition that each number has to be used a and no number can be repeated . What is the probability that first 4 digits of the code are even numbers ?
Answer:
0.0143 = 1.43% probability that first 4 digits of the code are even numbers.
Step-by-step explanation:
Arrangements of n elements:
The number of possible arrangements of n elements is given by:
[tex]A_{n} = n![/tex]
Probability:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Desired outcomes:
First four digits are even(2, 4, 6 and 8 are even, so arrangements of 4 elements).
Last four digits are odd(1, 3, 5 and 7 are odd, so the last four elements are also arrangements of 4 elements). So
[tex]D = 4!*4! = 24*24 = 576[/tex]
Total outcomes:
Arrangements of 8 digits. So
[tex]T = A_{8} = 8! = 40320[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{576}{40320} = 0.0143[/tex]
0.0143 = 1.43% probability that first 4 digits of the code are even numbers.

Find the circumference of a button if its radius is 15 mm
Answer:
94.25mm
........................
Answer:
94.25 mm
Step-by-step explanation:
The circumfrence of a cirlce can be found using the following formula:
C = 2 x PI x R
Circumfrence = 2 x 3.14 x 15
= 94.25
The diameter of a circle is 10 m. Find its area to the nearest tenth.
Answer:
78.54 m^2
Step-by-step explanation:
The computation of the area of the circle is shown below:
As we know that
Area of the circle = πr^2
Also
Diameter = 2r
10 = 2r
r = 5
So, the area of the circle is
= 3.14 × 5^2
= 78.54 m^2

An airplane is observed to be approaching the air point. It is at a distance of 12 km from the point of observation and makes an
angle of elevation of 50 degree. Find the height above the ground.
Answer:
The height is 14.3 km
Step-by-step explanation:
Given
[tex]distance= 12km[/tex]
[tex]\theta= 50[/tex] --- angle of elevation
Required
Determine the height above the ground
The question is illustrated using the attached image.
To calculate the required height, we make use of:
[tex]tan(\theta) = \frac{AB}{BC}[/tex]
Where AB represents the height and BC, the distance.
So:
[tex]tan(50) = \frac{AB}{12}[/tex]
Make AB the subject
[tex]AB = 12 * tan(50)[/tex]
[tex]AB = 12 * 1.1918[/tex]
[tex]AB = 14.3016[/tex]
[tex]AB = 14.3km[/tex] --- approximated
The height of the airplane above the ground is 9.19 km.
Trigonometric ratioTrigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let h represent the height of the airplane above the ground. Hence:
sin(50) = h / 12
h = 9.19 km
The height of the airplane above the ground is 9.19 km.

Dan enlarged the size of a rectangle to a height of 22.4 in. What is the new width of the rectangle if it was originally 5.6 in tall and 1.4 in wide
Answer:
The new width is 5.6 in
Step-by-step explanation:
Given
New
[tex]H_2 = 22.4[/tex]
Old
[tex]H_1 = 5.6[/tex]
[tex]W_1 = 1.4[/tex]
Required
The new width
This is calculated using the following equivalent ratio
[tex]H_2 : W_2 = H_1 : W_1[/tex]
[tex]22.4 : W_2 = 5.6 : 1.4[/tex]
Express as fraction
[tex]W_2/22.4 = 1.4/5.6[/tex]
Multiply both sides by 22.4
[tex]W_2= 1.4/5.6 * 22.4[/tex]
[tex]W_2= 5.6[/tex]

Write an equation of the parabola shown.
Answer:
y = 0.1(x + 5)² + 1.5
Step-by-step explanation:
Equation of a parabola having vertex at (h, k) is given by,
y = a(x - h)² + k
From the given graph, vertex of the parabola is (-5, 1.5)
Therefore, equation of the parabola will be,
y = a(x + 5)² + 1.5
Since, this parabola passes through a point (0, 4)
4 = a(0 + 5)² + 1.5
4 = 25a + 1.5
25a = 2.5
a = 0.1
By substituting the value of 'a' in the equation of the parabola,
y = 0.1(x + 5)² + 1.5
