A cell phone weighing 2 ounces translates to 0.125 pounds, since there are 16 ounces in one pound.

Cell phones can weigh as little as 2 ounces. The first step in determining how much a cell phone can weigh in pounds is to know the conversion factor between ounces and pounds. Since there are 16 ounces in one pound, you can divide the weight of the cell phone in ounces by 16 to convert it to pounds. For a cell phone that weighs 2 ounces:

Therefore, a cell phone that weighs 2 ounces is equivalent to 0.125 pounds.

Final answer:

To estimate the difference between 615 and 342, round each number to the nearest ten or hundred and subtract. Rounding to the nearest hundred gives an estimate of 300, while rounding to the nearest ten gives an estimate of 280.

Explanation:

To estimate the difference between 615 and 342, you can round each number to the nearest ten or hundred and then subtract the rounded numbers. Here's the step-by-step process:

This gives an estimate of the difference between 615 and 342 as 300.

If you prefer to round to the nearest ten instead, you'd get:

In this case, the estimate would be 280. You can choose the level of precision you want in your estimate based on how you round the numbers.

a. Set 2 has larger standard deviation.

b. Set 1 and set 2 have same standard deviation.

c. Set 2 has larger standard deviation.

a. Set 1: 4, 7, 7, 7, 10

Set 2: 4, 6, 7, 8, 10

It seems like Set 2 might have a larger standard deviation because the numbers are more spread out from the mean (which appears to be around 7).

The set 3 has larger standard deviation.

For Set 1:

Mean = (4 + 7 + 7 + 7 + 10) / 5

= 7

Standard Deviation = ([tex]\sqrt{\frac{(4-7)^2 + (7-7)^2 + (7-7)^2 + (7-7)^2 + (10-7)^2)}{5}[/tex]]

= 1.89

For Set 2:

Mean = (4 + 6 + 7 + 8 + 10) / 5

=7

Standard Deviation = ([tex]\sqrt{\frac{(4-7)^2 + (6-7)^2 + (7-7)^2 + (8-7)^2 + (10-7)^2)}{5}[/tex]]

= 2

Hence, set 2 has larger standard deviation.

b. Set 1: 100, 140, 150, 160, 200

Set 2: 10, 50, 60, 70, 110

Here, Set 1 seems to have same standard deviation as set 2.

For set 1:

Mean = (100 + 140 + 150 + 160 + 200) / 5 = 150

Standard Deviation =[tex]\sqrt{\frac{(100-150)^2 + (140-150)^2 + (150-150)^2 + (160-150)^2 + (200-150)^2)}{5}}[/tex]

= 32.24

For set 2:

Mean = (10 + 50 + 60 + 70 + 110) / 5

= 60

Standard Deviation =  [tex]\sqrt{\frac{(10-60)^2 + (50-60)^2 + (60-60)^2 + (70-60)^2 + (110-60)^2)}{5}}[/tex]

=32.24

Hence, set 1 and set 2 have same standard deviation.

c. Set 1: 10, 16, 18, 20, 22, 28

Set 2: 48, 56, 58, 60, 62, 70

Set 2 generally has larger values, suggesting that it could have a larger standard deviation because the mean is larger for set 2.

For Set 1:

Mean = (10 + 16 + 18 + 20 + 22 + 28) / 6

= 19

Standard Deviation = [tex]\sqrt{\frac{(10-19)^2 + (16-19)^2 + (18-19)^2 + (20-19)^2 + (22-19)^2 + (28-19)^2)}{6}}[/tex]

= 5.50

For Set 2:

Mean = (48 + 56 + 58 + 60 + 62 + 70) / 6

= 58.33

Standard Deviation = [tex]\sqrt{\frac{(48-58.33)^2 + (56-58.33)^2 + (58-58.33)^2 + (60-58.33)^2 + (62-58.33)^2 + (70-58.33)^2)}{6}}[/tex]

=6.641

Hence, the second set have the larger standard deviation.

To find the number of red bricks used to build the decorative wall, we can set up a system of equations. By solving the equations, we find that all 140 bricks used were red bricks.

To find the number of red bricks used, we can set up a system of equations.

Let r represent the number of red bricks and g represent the number of grey bricks.

We know that there were 140 bricks used in total, so we can write the equation: r + g = 140.

Since we specifically want to find the number of red bricks, we can write the equation: r = 140 - g.

By substituting this expression for r in the first equation, we get: 140 - g + g = 140.

Simplifying the equation, we find that 140 - g + g = 140 - g + g = 140.

Therefore, 140 - g = 140, and solving for g, we find that g = 0.

This means that no grey bricks were used and all 140 bricks used were red bricks.

Sample Response:: If the square root is not a perfect square, then an approximation of the root often makes more sense in the context of the problem. For real-world problems, you would want an approximation, so you have an estimate of the length you are looking at.

The relationship between the books and the students is an illustration of a linear function

The formula for the function is: [tex]b(s) = 560 - 3s[/tex]

From the question, we have:

[tex]b = 560[/tex] --- number of books in the morning

[tex]r = 3[/tex] ---- the number of books per students

So, the number of books as a function of number of students is:

[tex]b(s) = b - r \times s[/tex]

Substitute known values

[tex]b(s) = 560 - 3 \times s[/tex]

[tex]b(s) = 560 - 3s[/tex]

Step-by-step explanation:

Given that The top of a 22-foot ladder rests against the top of an 18-foot wall.

The ladder, the wall and the floor together make a right angled triangle with hypotenuse as ladder.

Thus we have a right triangle with hypotenuse = 22 ft

and the side of the wall = 18

The required angle is the angle  the ladder form with the ground.

Hence we have if x is the angle

[tex]sin x =\frac{Opposite}{Hypotenuse} =\frac{18}{22}[/tex]

From this we can find the angle X

X = sin inverse of 18/22

X=54.9

Round it off to X=55 degrees

The exact value of the expression √180 - √125 + √5 simplifies to 2√5, by combining like terms after simplifying each square root separately.

The exact value of the expression [tex]\sqrt{180}[/tex] - [tex]\sqrt{125}[/tex] + [tex]\sqrt{5}[/tex] can be calculated by simplifying each square root separately. Firstly, the [tex]\sqrt{180}[/tex] can be simplified to 6√5, because 180 = 36 × 5, and 36 is a perfect square whose square root is 6. Similarly, the [tex]\sqrt{125}[/tex] simplifies to 5√5, since 125 = 25 × 5 and the [tex]\sqrt{25}[/tex] is 5. The [tex]\sqrt{5}[/tex] remains as it is because it cannot be simplified further.

The expression then becomes 6√5 - 5√5 + √5. Now, we combine like terms. Since all terms involve the [tex]\sqrt{5}[/tex], we can combine them as follows: (6 - 5 + 1)√5, which simplifies to 2√5. Therefore, the exact value of the expression is 2√5.

The conversion of the expression 6^2=36 into logarithmic form results in log6(36) = 2. This method involves identifying the base (6), the exponent (2), and the result (36) in the original exponential equation.

In mathematics, you can interchange between an exponential form and a logarithmic form. Your given expression is 6^2=36, which is in exponential form.

To change this into logarithmic form, identify the base (which is 6 in this case), the exponent (which is 2), and the result (which is 36). The logarithmic form of the equation would then be 'log base 6 of 36 is 2'.

So, written in the usual mathematical notation, your answer would be log6(36) = 2. Here, 'log' stands for logarithm; the number following 'log' (6 in this case) is the base, the term within parentheses (36 in this case) is the number we're taking log of, and '2' is the value of the logarithm.

The equivalent expression to (3 x 1,000) + (3 x 10) + (3 x 1/100) + (3 x 1/1000) is 3030.033. This result doesn't require simplification through Exponential or Scientific notation since it's not an especially large or small value.

The student's question is asking for an alternative way to write the number produced by the mathematical operation: (3 x 1,000) + (3 x 10) + (3 x 1/100) + (3 x 1/1000). This is a combination of addition and multiplication involving decimal places. It can also be expressed in exponential notation:

So, another way to write the stated combination of multiplication and addition operations is 3030.033. The Exponential notation might not be an ideal replacement in this specific case since the result is not a large or small number which normally requires this notation. Scientific notation, (which uses powers of ten to express larger or smaller numbers), could most effectively be implemented if our final result was a very large or very small number.

Answer:  The required probability is 0.9.

Step-by-step explanation:  Given that Anna is shopping for a new backpack. The probability that the backpack is pink is 0.7, the probability that it is canvas is 0.7 and the probability that it is pink and canvas is 0.5.

We are to find the probability that the backpack is either pink or canvas.

Let, 'A' and 'B' be the events that the backpack is pink and canvas respectively.

Then, according to the given information, we have

[tex]P(A)=0.7,~~P(B)=0.7,~~P(A\cap B)=0.5,~~~P(A\cup B)=?[/tex]

From the law of probability, we have

[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\\Rightarrow P(A\cap B)=0.7+0.7-0.5\\\\\Rightarrow P(A\cap B)=1.4-0.5\\\\\Rightarrow P(A\cap B)=0.9.[/tex]

Therefore, the required probability that the backpack is either pink or canvas is 0.9.
