Answers

Answer 1

Answer

i) 4% = 0.04

ii) 76% = 0.76

iii) 120% = 1.20

iv) 100% = 1.00

v) 32.5% = 0.325

Explanation

The key to writing percents as decimals is to divide the percents by 100 to get the decimal equivalent.

i) 4% = (4/100) = 0.04

ii) 76% = (76/100) = 0.76

iii) 120% = (120/100) = 1.20

iv) 100% = (100/100) = 1.00

v) 32.5% = (32.5/100) = 0.325

A map state where your friend lives have a scale 1/2 inch: 10 miles.
Your friend measured the distance between her town and the state capital on the map. Her measurements were 4 1/2 inches. Based on your friend's measurement, what is the actual distance in miles between her town and the state capital?

Answers

The actual distance is 90 miles between the town and the state capital based on the scale of the map

1/2 inch on the map = 10 miles

So, 1 inch = 20 miles

Distance between the town and state capital = 4 1/2 inches

The mathematical relationship between a small unit of measurement on a map, such as an inch or centimetre, and the corresponding real-world unit of distance, such as a kilometre or a mile, is known as a map scale.

The actual distance in miles between the town and the state capital is given by:

Distance between town and state capital* Scale of the map

Answers

Hello there. To solve this question, we have to remember some properties about conversion of values.

1. How many 2-liter bottles of soda will you need to fill ten 500 mililiter containers?

First, multiply the number of containers by its capacity, that is

[tex]10\cdot500=5000\text{ mililiters}[/tex]

Notice that 1000 mililiters is equivalent to 1 liter, hence

[tex]5000\text{ mililiters }=5\text{ liters}[/tex]

To fill these containers with 2-liter bottles of soda, you'll need at least 3 bottles.

The answer to the first question is 3.

2. How many mililiter are 1/5 liter?

Considering 1 liter = 1000 mililiters, we have that

[tex]\dfrac{1}{5}\text{ liter }=\dfrac{1}{5}\cdot1000\text{ mililiters }=200\text{ mililiter}[/tex]

Hence the answer to this question is 2. 200

Answers

ANSWERS

(a) 0.420

(b) 0.400

(c) With a large number of spins, there might be a difference between the experimental and theoretical probabilities, but the difference should be small

EXPLANATION

(a) The experimental probability is given by,

[tex]P_{exp}=\frac{number\text{ }of\text{ }successes}{number\text{ }of\text{ }trials}[/tex]

In this case, Donna spun the dial 1000 times and 420 times it landed on yellow,

[tex]P_{exp}=\frac{420}{1000}=0.420[/tex]

Hence, the experimental probability of landing on yellow is 0.420.

(b) The theoretical probability is given by the geometry of the spinner and, if it is fair, the number of yellow sections,

[tex]P_{th}=\frac{number\text{ }of\text{ }favorable\text{ }outcomes}{total\text{ }posible\text{ }outcomes}[/tex]

In this case, the spinner is divided into 10 equally sized slices, and 4 of them are yellow,

[tex]P_{th}=\frac{4}{10}=0.400[/tex]

Hence, the theoretical probability of landing on yellow is 0.400.

(c) As we can see in parts a and b, for 1000 trials, the experimental and theoretical probabilities are almost the same - i.e. there is a small difference. This is known as the law of large numbers which states that if the number of trials of an experiment is large, the experimental probability of each event should be close to the theoretical probability.

Hence, the true statement is the first one: with a large number of spins, there might be a difference between the experimental and theoretical probabilities, but the difference should be small.

Answers

The mean absolute deviation is 2.5.

What is Mean Absolute Deviation?

The average distance between each data value and the mean is known as the mean absolute deviation (MAD) of a data collection. A measure of variance in a data collection is the mean absolute deviation. We may determine how "spread out" the values in a data collection are by looking at the mean absolute deviation.

How to calculate the mean deviation from the mean:

Calculate the mean of the provided observations.Determine how much each observation differs from the estimated mean.Analyze the mean of the differences discovered in step two.

Given data:1, 1, 3, 5, 5, 6, 8, 11

So, mean of the data is

= 1+ 1 +3 +5 +5+ 6+ 8 +11 / 8

= 40 /8=

5

Now, Mean absolute deviation is

= | 1-5| + |1-5| + |3-5 | + |5-5| + |5-5| + |6-5| + |8-5| + |11-5|/ 8

= 4 + 4 + 2+ 0 + 0+ 1 + 3 +6 /8

= 20/8

=2.5

The costs of repairing iPads in UAE are normally distributed with a standard deviation 73 Dhs. If 8% of the costs exceed 279 Dhs, find the mean of the costs. Round your answer to the nearest diham.

Answers

The costs of repairing iPads in UAE are normally distributed with a standard deviation of 73 Dhs. If 8% of the costs exceed 279 Dhs, then the mean of the costs is 1.405072

The mean of the Costs stands for the typical sum of money spent on a product's production. Depending on how many units are made, this amount may change.

Let X be the price of fixing iPads in the UAE (in Dhs)

X ~ N (μ, σ = 73)

if 8% of the costs are greater than 297 Dhs.

P (X > 297) = 8%

P(X > 297) = 0.08

We must determine the mean value (μ)

P (X > 297) = 0.08

P [(X - μ) / σ > (297 - μ) / 73] = 0.08

P [Z < (297 - μ) / 73] = 0.08

P [Z < (297 - μ) / 73] = 1 - 0.08

P [Z < (297 - μ) / 73] = 0.92

(297 - μ) / 73 = Z⁻¹(0.92)

(297 - μ) / 73 = 1.405072    (Using R software)

297 - μ = 73 * 1.405072

μ = 297 - (73 * 1.405072)

μ = 297 - 102.5702

μ = 194.4298

μ ≅ 194

Therefore, the mean of the cost (μ) = 194 dhs.

Using R Software, we can compute;

Z⁻¹ (0.92) is,

=qnorm(0.92) ` → (Command)

Write a function and use a table and graph to predict when the population will reach 20,000

Answers

The formula for exponential growth is expressed as

y = a(1 + r)^t

where

y is the population after t years

ais the initial population

r is the growth rate

t is the number of years

From the information given,

a = 350

r = 14% = 14/100 = 0.14

By substituting these values into the equation, the function to model th growth rate is

y = 350(1 + 0.14)^t

y = 350(1.14)^t

We would substitute values of t into the equation to determine corresponding values of y. We have

For t = 2, y = 350(1.14)^2 = 454.86

For t = 6, y = 350(1.14)^6 = 768.24

For t = 10, y = 350(1.14)^10 = 1297.52

We would plot these values of y on the y axis and the corresponding values of t on the x axis. The graph is shown below

The time when the population will reach 20000 would be the value of x at the point where y = 20000 on the graph. It is around y = 30.87

Thus, the population will reach 20000 in approximately 31 years

We can confirm this by solving the equation. We have

20000 = 350(1.14)^t

20000/350 = 1.14^t

57.14 = 1.14^t

Taking natural log of both sides, we have

ln 57.14 = ln1.14^t = tln1.14

t = ln 57.14/ln1.14

t = 30.87505

The polygon EFGH is a polygon.

What is polygon?

A polygon is a form of planar figure in geometry and is defined as a closed polygonal chain made up of a finite number of straight line segments. A region that is enclosed by a bounding plane, a bounding circuit, or both is referred to as a polygon. The portions of a polygonal circuit are referred to as its edges or sides.

To check the polygon EFGH is a square or not, first to find the length of each side of polygon.

If the length of each side is equal then the polygon EFGH is a square.

(Since length of each side of square is equal).

We know,

[tex]d \sqrt{(x_2-x_1)^2 + (y_2 - y_1)^2}[/tex]

where,

d = distance

[tex](x_1, x_2)[/tex] = Coordinates of the first point.

[tex](x_2, y_2)[/tex] = Coordinates of the second point.

So,

[tex]EF = \sqrt{(3-(-2))^2 + (3.5-3.5)^2} = \sqrt{25 + 0} = 5[/tex]

[tex]FG = \sqrt{(3-3)^2 + (-1.5-3.5)^2 } = \sqrt{0 + 25} = 5[/tex]

[tex]GH = \sqrt{(-2-3)^2 + (-1.5-(-1.5))^2} = \sqrt{25 + 0} = 5[/tex]

[tex]EH = \sqrt{(-2-(-2))^2 + (-1.5-3.5)^2} = \sqrt{0 + 25} = 5[/tex]

From above the length of each side is equal.

• Yes

Explanation:

(a)Han cellphone's plan costs a fixed fee of $200 and an extra $50 per month.

Therefore:

[tex]\begin{gathered} \text{The total cost for one month=}200+50 \\ =\$250 \end{gathered}[/tex]

(b)If Han uses the phone for x months

Extra Cost = 50x

(c)Since the number of months = x; and

Total cost for x months = y

When x=24

[tex]\begin{gathered} y=200+50(24) \\ =1400 \end{gathered}[/tex]

The graph that shows the cost of the cell phone plan over a period of two years using months as the units of time is Graph A.

(d)We see that the equation y=50x+200 has a proportional constant (50).

Another approach is to say that it is a linear equation.

Therefore, there is a proportional relationship between time and the cost of the cell phone plan.

Each ball in the ball pit is the same size. They each have a diameterof 4 inches. 1. What is the volume of this pool? 2. How many ball pit balls will we need to fill the pool up to the top?

Answers

Answer: We have to find the volume of the pool and the number of pit balls that can fill it.

(1) We can find the volume of the pool with the following formula:

[tex]V=L\times W\times D\rightarrow(1)[/tex]

Using the equation (1) the volume of the pool is determined as follows:

[tex]\begin{gathered} L=82ft \\ \\ W=41ft \\ \\ D=4.25ft \\ \\ \therefore\rightarrow \\ \\ \begin{equation*} V=L\times W\times D \end{equation*} \\ \\ V=(82ft)\times(41ft)\times(4.25ft)=14,288.5ft^3 \\ \\ V=14,288.5ft^3 \end{gathered}[/tex]

(2) The number of ball pits that can fill the pool is as follows:

[tex]\begin{gathered} V_b=\frac{4}{3}\pi r^3 \\ \\ \\ 4in=\frac{1}{3} \\ \\ \therefore\rightarrow \\ \\ V_b=\frac{4}{3}\pi(\frac{1}{3})^3=\frac{4}{81}\pi ft^3 \\ \\ V_b=\frac{4}{81}\pi ft^3=0.16ft^3 \end{gathered}[/tex]

Therefore the answer is:

When given a line of 3x + 6y = 8, how do you find slope intercept?

Answers

The line is given by 3x + 6y = 8

To find the slope and the y-intercept, we must rewrite the equation in the form y = ax + b, where a is the slope and b is the y-intercept.

The first step is subtract 3x from both sides of the equation:

3x + 6y - 3x = -3x + 8

6y = -3x + 8

Then, we divide both sides by 6:

6y/6 = (-3x + 8)/6

y = -x/2 + 4/3

Therefore, the slope is -1/2 and the y-intercept is 4/3

Calculate the perimeter for each of the following ​

Answers

a) Perimeter =  17.4 cm

b) Perimeter   =210.6 cm

How are the perimeters calculated?

a) The perimeter of an irregular polygon = Sum of all the sides of the polygon.

Converting value of all sides to centimetres.

Perimeter = 3.4 +3.2 +4.3 +3.7+2.8

                 = 17.4 cm

b) The perimeter of an irregular polygon = Sum of all the sides of the polygon.

Converting value of all sides to centimetres.

Perimeter = 29.1+25.3+30+28.6+32.6+36.5+28.5

                 =210.6 cm

What is the perimeter of a polygon?

The total length of a polygon's boundary is what is referred to as its perimeter. To put it another way, a polygon's perimeter is equal to the sum of its sides. Due to the fact that polygons are closed plane shapes, their perimeters likewise reside in a two-dimensional plane.If the lengths of the sides of a polygon are known, it is possible to determine its area and perimeter.

A fair die is rolled 4 times. What is the probability of having no 1 and no 3 among the rolls? Round your answer to three decimal places.

Answers

Answer:

Step-by-step explanation:

You have to assume each roll is independent. The probability of rolling a fair die is 1/6. When you roll the die, you only care about 2,4,5, and 6 since you do not want to get 1 or 3. So the probability is of getting a 2,4,5 and 6 is 4/6.

You could of also see it as the probability of NOT getting a 1 or 3 is:

[tex]1-\frac{2}{6} =\frac{4}{6}=\frac{2}{3}[/tex]

Now you roll the die 4 times with each success being 2/3

[tex]\frac{2}{3} \cdot \frac{2}{3} \cdot \frac{2}{3} \cdot \frac{2}{3} =(\frac{2}{3})^4=.197530864[/tex]

without graphing, describe the transformation of each parabola or absolute value function y = 2 |x|+ 1

Answers

Remember the following transformations of a function:

[tex]c\cdot f(x)[/tex]

This transformation stretches the function over the vertical axis if c>1 and shrinks it if 0

If c is positive, the orientation is mantained, and if c is negative, the function is also flipped over (it shrinks if -1

[tex]f(x)+c[/tex]

This transformation moves the function vertically c units. It goes up if c>0 and down if c<0.

Therefore, starting with the absolute value function:

[tex]\lvert x\rvert[/tex]

Multiply the function by 2:

[tex]2\cdot\lvert x\rvert[/tex]

Since 2>1, then this is a vertical stretching by a factor of 2.

Next, add 1:

[tex]2\cdot\lvert x\rvert+1[/tex]

This will translate the stretched absolute value function one unit upwards.

Therefore, the complete description of the transfromation would be:

[tex]y=2\cdot\lvert x\rvert+1[/tex]

Is a vertical stretching of the absolute value function by a factor of 2, translated 1 unit upwards.

Describe the end behavior of f(x) = −3x4 + 7x2 − x + 13.

Answers

The end behavior of the given function will be given by Down on the left down on the right.

A function may be defined as the expression in which for one value of input variable there is only one value of output variable. The input variable or the independent variable is x, and the output variable or the dependent variable is y. In the given function f(x) = -3x⁴ + 7x² - x + 13 we will use the Power and Polynomial Functions features. For final behavior of power functions of the form f(x) = axⁿ where n is represented as a non-negative integer depends on the power and the constant. Here, the leading coefficient is -3x⁴. So, when x → ∞ the value of f(x) → -∞ and when x → -∞ then the value of f(x) → -∞. So, the final answer for the behavior will be given by "Down on the left, down on the right".

What is a trillion?1,000,000,000,000One trillion is equal to one million million, or 1,000,000,000,000, and on the short scale, we write this as 1012. (ten to the twelfth power). This number is now commonly referred to as one trillion because it is a thousand times bigger than the short-scale billion.We need to determine how many crores one trillion represents. Therefore, by dividing one trillion by one crore, we can find the solution to the puzzle. As a result, we discover that 100000  = 1000000000000/10000000. As a result, we learn that $1 trillion is equivalent to 100,000 Indian Rupees.

So, 1 trillion to the tenth power:

1 trillion to the tenth power = (10¹⁴)¹⁰ or  (10¹³)¹⁰

Therefore, 1 trillion to the tenth power is (10¹⁴)¹⁰ or  (10¹³)¹⁰.
