The ages of students in a school are normally distributed with a mean of 15 years and a standard deviation of 2 years. Approximately what percent of the students are between 14 and 18 years old?
We have been given that the ages of students in a school are normally distributed with a mean of 15 years and a standard deviation of 2 years.
We are asked to find the percentage of students that are between 14 and 18 years old.
First of all, we will find z-score corresponding to 14 and 18 using z-score formula.
[tex]z=\frac{x-\mu}{\sigma}[/tex]
[tex]z=\frac{14-15}{2}[/tex]
[tex]z=\frac{-1}{2}[/tex]
[tex]z=-0.5[/tex]
Similarly, we will find the z-score corresponding to 18.
[tex]z=\frac{18-15}{2}[/tex]
[tex]z=\frac{3}{2}[/tex]
[tex]z=1.5[/tex]
Now we will find the probability of getting a z-score between [tex]-0.5[/tex] and [tex]1.5[/tex] that is [tex]P(-0.5<z<1.5)[/tex].
[tex]P(-0.5<z<1.5)=P(z<1.5)-P(z<-0.5)[/tex]
Using normal distribution table, we will get:
[tex]P(-0.5<z<1.5)=0.93319-0.30854[/tex]
[tex]P(-0.5<z<1.5)=0.62465[/tex]
Let us convert [tex]0.62465[/tex] into percentage.
[tex]0.62465\times 100\%=62.465\%\approx 62.5\%[/tex]
Therefore, approximately [tex]62.5\%[/tex] of the students are between 14 and 18 years old.

A person on a moving sidewalk travels 56 feet in 8 seconds. The moving sidewalk has a length of 140 feet. How long will it take to move from one end to the other?
Answer:
The answer is : 20 seconds
Step-by-step explanation:
First, we are told that it takes the person 8 seconds to travel 56 feet, hence, we will find the time it takes to travel one foot.
56 feet = 8 seconds
∴ 1 foot = 8/56 seconds
Next, we are told that the length of the sidewalk is 140 feet, therefore walking from one end of the sidewalk to the other is the the same as walking 140 feet, and this is calculated thus:
1 foot = 8/56 seconds (calculated above)
∴ 140 feet = 8/56 × 140 = 20 seconds

The domain is: - infinity
Answer for the first blank = infinity
Answer for the second blank = 9000
===================================================
Explanation:
Note how the graph goes on forever in both left and right directions. So x extends forever in both directions. This means any x can be an input to the function. The domain is -infinity < x < infinity. Basically, the domain is the set of all real numbers.
The range is -infinity < y <= 9000 since there is no smallest y value, but the largest y can be is y = 9000. Look at the highest point of the parabola and note the y coordinate of this point. This highest point is called the vertex.

Tyler went to an electronics store with a gift card. After he spent 13/20 of the gift card's value on a video game, the card's value was less than $26.25. Which inequality describes x, the value of the gift card when Tyler entered the store?
Answer:
[tex]\frac{7}{20}x < 26.25[/tex]
Step-by-step explanation:
If $x is the value of the gift card when Tyler entered the store, then after spending [tex]\frac{13}{20}[/tex] of the gift card the card's value was less than $26.25.
So, we can write the inequality as
[tex]x - \frac{13}{20}x < 26.25[/tex]
⇒ [tex]\frac{7}{20}x < 26.25[/tex]
So, this is the required inequality that describes x, the value of the gift card when Tyler entered the store. (Answer)
Each day he will fill 5 cups more. Write an algebraic expression to represent the number of cups he will have after n days. Identify the coefficient.
Answer:
5n
The coefficient is 5
Step-by-step explanation:
For day 1; he fill 5 cups
For day 2; he fill 5 + 5 cups
For day 3; he fill 5 + 5 + 5 cups
For day 4; he fill 5 + 5 + 5 + 5 cups
For day n; ?
The sequence is 5, 10, 15, 20, ...
The sequence increases linearly.
a = 5, d = 5, n = ?
Using the Formula for nth term of a sequence, we have:
[tex]T_{n} = a + (n - 1)d\\T_{n} = 5 + (n - 1) 5\\T_{n} = 5 + 5n -5\\T_{n} = 5 - 5 + 5n\\T_{n} = 5n[/tex]

Frederick made a quilt for his cousin's doll. The quilt had a 7 × 7 array of different color square patches. If each patch is 3 1 2 in long, what is the area of the whole quilt?
Answer:
Step-by-step explanation:
Given that, .
Frederick make 7 × 7 quilt array
This shows that there are seven rows and there are seven columns.
So, the total quilt is
7 × 7 = 49 squares patches
We are told that each of this square patches are 3½ in long
Then, since it is a square patch, it's area is
A = S² = 3½ × 3½ = 12¼ in²
So, each square patch has an area of 12¼in²,
Then, for 49 square patches
The total area of 49 Square patches is
A = 49 × 12¼ = 600.25 in²
So, the area of the whole quilt is 600.25 in²
Answer:
The area of the whole quilt is 600.25 ft²
Step-by-step explanation:
Here we have the length of each patch given as [tex]3\frac{1}{2} in[/tex]
Therefore, whereby the quilt had 7 × 7 array of different color square patches, we have;
Length of each side of quilt = [tex]7 \times 3\frac{1}{2} = 7 \times \frac{7}{2} = \frac{49}{2} = 24\frac{1}{2}[/tex]
∴ Area of the whole quilt = [tex]24\frac{1}{2} \times 24\frac{1}{2} = \frac{2401}{4} = 600\frac{1}{4} \ ft^2[/tex]
The area of the whole quilt = 600.25 ft².

The solution to the quadratic equation is x = -4
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
2x² + 8x = x² - 16
Subtracting x² on both sides , we get
x² + 8x = -16
Adding 16 on both sides , we get
x² + 8x + 16 = 0
On simplifying the equation , we get
( x + 4 )² = 0
Taking square roots on both sides , we get
x + 4 = 0
Subtracting 4 on both sides , we get
x = -4
Therefore , the value of x is -4
Hence , the solution is x = -4

A toy company is considering a cube or sphere-shaped container for packaging a new product. The height of the cube would equal the diameter of the sphere . Compare the volume to surface area ratios of the containers. Which packaging will be more efficient? For a sphere, SA =4πr²
Answer:
Packaging with cube will be more efficient.
Step-by-step explanation:
Given:
A cube and a sphere where the diameter of the sphere is equal to the height of the cube.
Let the height of the cube "x"
Radius of the sphere = [tex](\frac{x}{2})[/tex]
Formula to be used:
Surface area of the cube = [tex]6x^2[/tex] and Surface area of the sphere = [tex]4\pi (r)^2[/tex]
Volume of the cube = [tex]x^3[/tex] and Volume of the sphere = [tex]\frac{4\pi r^3}{3}[/tex]
We have to compare the ratio of SA and Volumes.
Ratio of SA : Ratio of their volumes :
⇒ [tex]\frac{SA\ of\ cube\ (S_1)}{SA\ of\ sphere\ (S_2)}[/tex] ⇒ [tex]\frac{Volume \ of \ cube\ (V_1)}{Volume\ of\ sphere\ (V_2)}[/tex]
⇒ [tex]\frac{6x^2}{4\pi (\frac{x}{2})^2}[/tex] ⇒ [tex]\frac{x^3}{\frac{4 \pi r^3}{3} }[/tex]
⇒ [tex]\frac{6x^2}{4\pi (\frac{x^2}{4})}[/tex] ⇒ [tex]\frac{x^3}{\frac{4 \pi (\frac{x}{2})^3}{3} }[/tex]
⇒ [tex]\frac{6x^2}{\pi x^2}[/tex] ⇒ [tex]\frac{x^3}{\frac{4 \pi (\frac{x^3}{8})}{3} }[/tex]
⇒ [tex]\frac{6}{\pi}[/tex] ⇒ [tex]\frac{6}{\pi}[/tex]
⇒ approx [tex]2[/tex] ⇒ approx [tex]2[/tex]
⇒ [tex]S_1=2S_2[/tex] ⇒ [tex]V_1=2V_2[/tex]
Packaging of the toy with the cube will be more efficient as it has more volume comparatively.

If f(x)= 3x-9, fine each function value.
F(12)
Answer:
27
Step-by-step explanation:
Plug in 12 every time you see "x". When you do this it should be f(12) = 3(12) - 9 = 36 - 9 = 27.
Hope this helped :)
The function value f(12) for f(x) = 3x - 9 is calculated by substituting x with 12, resulting in f(12) = 3(12) - 9, which simplifies to f(12) = 27.
Explanation:To find the value of f(12) for the given function f(x) = 3x - 9, you simply substitute the value of 12 for x and then perform the calculation:
f(12) = 3(12) - 9
f(12) = 36 - 9
f(12) = 27
Therefore, the function value of f(12) is 27. When plotting or using a graph, this is the y-coordinate when x is 12 for the equation y = 9 + 3x, which has a slope ('m') of 3 and a y-intercept ('b') of 9.
