The approximately 99.7% of the students have commute distances between 13.9 miles and 24.1 miles, the area within two standard deviation is 95%
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
a) We have:
mean u = 19.0 miles,
[tex]\rm \sigma = 5.1 \ miles[/tex]
According to the empirical rule, the area between [tex]\mu - \sigma[/tex] and [tex]\mu + \sigma[/tex] is 99.7%
[tex]\mu - \sigma = 19- 5.1 = 13.9[/tex]
[tex]\mu + \sigma = 19+5.1 = 24.1[/tex]
b) = P(8.8 < X < 29.2)
[tex]\rm P(\dfrac{8.8-\mu}{\sigma } < \dfrac{X-\mu}\sigma < \dfrac{29.2-\mu}{\sigma})[/tex]
[tex]\rm P(\dfrac{8.8-19}{5.1} < Z < \dfrac{29.2-19}{5.1})[/tex]
P(-2 < Z < 2)
Thus, the approximately 99.7% of the students have commute distances between 13.9 miles and 24.1 miles, the area within two standard deviation is 95%

6^2+4^2=C^2
Answer: c = about 7.21
Step-by-step explanation:
ok - pythagorean theorum
6^2+4^2=C^2
36 + 16 = c^2
52 = c^2
root both sides
c = about 7.21
The solution to the equation 6^2 + 4^2 = C^2 is approximately 7.21
How to solve the equation?The equation is given as:
6^2 + 4^2 = C^2
Evaluate the exponents of 6 and 4
36 + 16 = C^2
Evaluate the sum
52 = C^2
Take the square root of both sides
7.21 = C
Rewrite as:
C = 7.21 (approximated)
Hence, the solution to the equation is approximately 7.21

For -3y+2x=-18 determine the value of y when x = 0, and the value of x when y = 0.
Hello!
We have two different scenarios that we have to solve in the question. We will be solving for both the x and y variable.
We were given the equation: -3y + 2x = -18
To solve for our variables, we will use the values given in our question.
Solve:
Lets solve for the value "y", where our x = 0
Plug in 0 to x and solve:
-3y + 2(0) = -18
-3y = -18
y = 6
Lets now solve for the value "x", where our y = 0
Plug in 0 to y and solve:
-3(0) + 2x = -18
2x = -18
x = -9
Therefore, our answers would be: y = 6, x = -9
Answer:
y = 6
x = -9

A scale drawing of a kitchen is shown below. The scale is 1 : 20. A rectangle is shown. The length of the rectangle is labeled 4 inches. The width of the rectangle is labeled 5 inches. Show your work to determine the area of the room in square feet.
Answer: 55 [tex]\frac{5}{9}[/tex] feet² or 55.556 feet²
Step-by-step explanation:
The scale means that for ever one in the scale drawing, it is 20 in the actual room. We will convert the dimensions using proportions.
[tex]\frac{5}{x}=\frac{1}{20}[/tex]
100 = x
-> The length is 100 inches
[tex]\frac{4}{x}=\frac{1}{20}[/tex]
80 = x
-> The width is 80 inches
The area of a rectangle can be found by multiplying the length by the width:
A = L * W
A = 100 * 80
A = 8,000 inches²
To get this into square feet, we will divide by 144. Why? There are 12 inches in a foot. 12 times 12 is 144.
8,000 inches² / 144 = 55 [tex]\frac{5}{9}[/tex] feet²
The area of the room, in square feet, is 55 [tex]\frac{5}{9}[/tex] feet².
15ml of Tylenol 3 to given every 4-6 hours. Your research indicates that there are 12mg of codeine per 5ml of liquid and that the safe dosage is between 0.5 and 1mg/kg/every 4-6 hours. Is this prescription safe for your child? Explain. If not, what would a safe dose be?
Answer:
If the safe dose is .5 to 1 mg/kg/dose, the safe limit depends on the side of the child. Using the more conservative limit of .5mg/kg, you have 36mg(kg/.5mg)=72kg, which is roughly 160lbs, Even with the upper limit of 1mg/kg, you still have 36mg(kg/1mg) = 36kg, or 80lbs, which is a larger child. I would say this dose isn't "safe", but you really need the weight of the child to calculate what is a safe dose.

How to evaluate the composite function?The functions are given as:
f(x) = 11x^3 - 3x^2
g(x) = 7x^4 + 9x^3
The value of f(x) . g(x) is calculated as:
f(x) . g(x) = (11x^3 - 3x^2) * (7x^4 + 9x^3)

Did I do it right? If the measure of ∠DAB=51∘, ∠CAB=x, and ∠DAC=x+1, find the measure of ∠CAB
If the measure of angles ∠DAB = 51° and the value of x is 25. Then the measure of angle ∠CAB will be 25°.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
If the measure of angles ∠DAB = 51°, ∠CAB = x, and ∠DAC = x + 1.
Then the measure of angle ∠CAB will be
We know
∠CAB + ∠CAD = ∠DAB
x + x + 1 = 51
2x = 50
x = 25
Then the measure of the angle ∠CAB will be
∠CAB = x
∠CAB = 25

A rectangular prism has a
length of 2 1/2yd, a width of 1 1/2yd, and a height
of 1 1/2yd. You use cubes with fractional edge
lengths of 1/2 yd to find the volume. How many
cubes are there for each of the length, width,
and height of the prism? What is the volume of
the prism?
Step-by-step explanation:
we need 2 1/2 × 2 = 5 cubes along the length.
1 1/2 × 2 = 3 cubes along the the width.
and 1 1/2 × 2 = 3 cubes along the height.
altogether we need
5×3×3 = 45 cubes
and the volume is
2 1/2 × 1 1/2 × 1 1/2 = 5/2 × 3/2 × 3/2 = 45/8 = 5 5/8 yd³
There are 96 cubes are there for each of the length, width, and height of the prism.
The volume of a rectangular prism is 12 yd³.
What is the prism?A prism is a three-dimensional solid object in which the two ends are identical. It is the combination of flat faces, identical bases, and equal cross-sections.
A rectangular prism has a length of 2 1/2yd, a width of 1 1/2yd, and a height
of 1 1/2yd.
length 2 1/2 and half yd = 2 1/2+ (1/2) yd = 5/2 + 1/2 = 6/2= 3 yd
Width 1 1/2 and half yd = 1 1/2 + (1/2) yd = 3/2 + 1/2 = (4/2) = 2 yd
Height 1 1/2 and half yd = 1 1/2 + (1/2) yd = 3/2 + 1/2 = (4/2) = 2 yd
Cubes of edge length (1/3) yd are used to fill the rectangular prism.
The length would contain (3) ÷ (1/2) = 6
The width would contain (2) ÷ (1/2) = 4
The height would contain (2) ÷ (1/2) = 4
How many cubes are there for each of the length, width, and height of the prism?
6 × 4 × 4 = 96 cubes
There are 96 cubes are there for each of the length, width, and height of the prism.
What is the volume of the prism?
The volume of rectangular prism = 3 × 2 × 2 = 12
