pencils come in packages of 18. erasers come in packages of 12. phillip wants to have the same number of pencils as erasers. how many packs of pencils and how many packs of eraser will he have to buy?

Answer:

6cm

Step-by-step explanation:

Given, the length of two sides of a triangle are 6 cm and 10 cm.

We have to find the length of the third side.

We know that the sum of the lengths of any two sides of a triangle is always greater than the length of the third side.

Sum of two sides = 6 + 10

= 16 cm

We know that the third side must be greater than the difference between two sides and less than the sum of two sides.

Difference of two sides = 10 - 6

= 4 cm

So, the third side must be greater than 4 cm and less than 16 cm.

Therefore, the third side is 6 cm.

13 number of runners run at most 2 miles per day .

calculation is explained below as

at 2 miles = 6 runners run

at 3 miles = 4 runners run

at 4 miles = 2 runners run

at 5 miles = 1runners run

on adding to calculate how many number of members run at most 2 miles per day is    = 6 + 4 + 2 + 1 = 13 .

hence 13  number of members run at most 2 miles per day .

A number line plot is a simple way of  visual representation of data patterns at the coordinate axis. on comparing the height of the specific columns,  the least frequently of occurring number can be calculated. The number line of plot becomes a bar graph when the  box is drawn around the Xs or dots in each and every column. A horizontal line, also called  as  x-axis, with equal intervals which are labelled with values which makes  a number line plot. Xs or dots can be used to describe or evaluate  the frequency in which a number, or a set a defined numbers, occurs on number line .

The calculator helps to slove an expression. By putting all elements one by one of the expression to get result.

What is a calculator?

A calculator is a device that performs numerical arithmetic operations. Basic calculators can only perform addition, subtraction, multiplication, and division calculations.

To perform basic operations, use the basic operation symbols. Addition (+), subtraction (-), multiplication (), and division () are examples of these operations.

Don't be concerned about the order of operations. A scientific calculator will perform calculations in the correct order.

Using the parentheses keys, you can change the order of operations. The calculator's order of operations will be overridden.

Correct your errors. If you accidentally press the wrong key, press the DEL key. This will remove the last button you pressed, but it will not remove any calculations you've made.

Make a clean sweep of your work. To clear the line, press the CLEAR button. You can probably scroll up to see previous calculations. You can delete these by pressing delete after each line.

Answer: Answer is 193% or c

Step-by-step explanation: To solve this, we can use algebra. Suppose x represents the percent of increase. 1.37 * x = 4.02. Divide both sides by 1.37 to get x = 2.93. This represents 293% However, since it is asking for the increasing, we need to subtract 100% since we only want to increase, not the total value.

Answer:

b. 393%

Step-by-step explanation:

1.37 + 1.37x% = 4.02

We can rewrite the expressions by using exponent properties:

(x⁵/3)³*81x⁴ = 3x¹⁹

Here we need to use some exponent properties, these are:

(xᵃ)ᵇ = xᵃᵇ

xᵃ/xᵇ = xᵃ⁻ᵇ

Here we have the expression:

(225a¹⁰)/(5a²)²

We can rewrite the denominator as:

(5a²)² = 25a⁴

We can rewrite it as:

(225a¹⁰)/ 25a⁴ = (225/25)*(a¹⁰/a⁴) = 9*a¹⁰⁻⁴ = 9a⁶

The other expression is:

Answer:

Step-by-step explanation:

To calculate the percent error, we use the formula:

(|(Actual distance - Estimated distance)| / Actual distance) * 100

So for this case:

(|(4.32 - 4.5)| / 4.32) * 100 = (0.18 / 4.32) * 100 = 0.041666666666666664 * 100 = 4.16666667%

Therefore, Kin's percent error is 4.16666667%.

It is important to note that the percent error can be positive or negative depending on whether the estimated value is higher or lower than the actual value.

So the answer is D-0.18%

The statistic is misleading because the sample is biased.

The collection of data is gathered and chosen from a statistical population with the use of some prescribed techniques in both statistics and quantitative methodology. Data sets may be divided into two categories: sample and population.

All the components of the data set are included in the population, which also contains quantifiable qualities like mean and standard deviation.

A sample is made up of one or more observations that are taken from the population, and a statistic is what makes a sample quantifiable. The act of sampling is the selection of a sample from a population.

The double integral. ∫∫R 2x/1 + xy dA, R = [0, 2] × [0, 1] is: 2*(1/2ln(3) - 1/2ln(1))

To calculate the double integral ∫∫R 2x/1 + xy dA, we need to integrate with respect to x and y over the region R = [0, 2] × [0, 1].

We can solve this by using the order of integration.

First we need to fix the limits of integration with respect to y and then integrate with respect to x.

∫∫R 2x/1 + xy dA = ∫(0 to 1) (∫(0 to 2) 2x/(1+xy) dx) dy

∫(0 to 1) (∫(0 to 2) 2x/(1+xy) dx) dy = ∫(0 to 1) ( 2*ln(1+xy)|x=0 to 2) dy

∫(0 to 1) ( 2ln(1+2y) - 2ln(1+0) ) dy

= 2*∫(0 to 1) ln(1+2y) dy

= 2*[y*ln(1+2y) - ∫(0 to 1) ln(1+2y) dy] |y = 0 to 1

= 2*[yln(1+2y) - (1/2 ln(3) - 1/2* ln(1))] |y = 0 to 1

= 2*(1ln(3) - 0ln(1) - 1/2* ln(3) + 1/2* ln(1))

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Given are two linear equations,

y = -x + 4 and

y = 2x - 2

First graph the lines.

For that, find two points on each equation and join them.

x = 0, then y = 4

y = 0, then x = 4

We have two points (0, 4) and (4, 0). Join these points to form the line.

x = 0, then y = -2

y = 0, then x = 1

We have two points (0, -2) and (1, 0). Join these points to form the line.

We have two equations, which are equal to each other.

-x + 4 = 2x - 2

-x - 2x = -2 - 4

-3x = -6

x = 2

y = -2 + 4 = 2

An arborist sights the top of a tree using a clinometer and reads the angle of elevation to be 29º, The height of the tree is 17.03 meters

Generally, To find the height of the tree, we can use the tangent function and some basic trigonometry. The tangent of an angle is the ratio of the opposite side (the height of the tree) to the adjacent side (the distance from the base of the tree to the clinometer).

tan(29) = opposite / adjacent

We know that the distance from the clinometer to the base of the tree is 28 meters, and that the clinometer is 1.5 meters above ground level.

So we can use the Pythagorean theorem to find the adjacent side:

adjacent = √(28^2 + 1.5^2)

= 28.03 meters

Now we can use the tangent function to find the opposite side:

opposite = tan(29) * adjacent

Using a calculator we can get the opposite = 15.53 meters

The height of the tree is opposite + 1.5 (the clinometer height) '

= 15.53 + 1.5

1.81 value of z should we use when making a 93% confidence interval for p. This can be solved using the concept of z-table.

The difference from the mean is expressed as a z-score in standard deviation units. It is not clear either one agree or disagree with the null hypothesis. The likelihood that a point as severe as their statistic would be seen that under null hypothesis is known as the p-value.

A z-table, sometimes referred to as the standard normal table, gives the area beneath the curve to the left of a z-score. This region indicates the likelihood that z-values will fall inside a particular area of the standard normal distribution.

At 93% confidence level the z is:

α = 1 - 93%

α = 1 - 0.93

α = 0.07

Now, α /2 = 0.035

Emmy answered average of 60 out of 75 math problems correctly on the quiz she took last week, meaning she answered a total of 60 problems correctly.

60/75 = 0.8

0.8 x 75 = 60

Emmy took a math quiz last week and answered 60% of the 75 problems correctly. To calculate how many problems Emmy got correct, we need to divide 60 by 75, which gives us 0.8. Then, we multiply 0.8 by 75, which gives us 60. This means that Emmy correctly answered 60 out of 75 math problems on the quiz. This is equivalent to 60%, which is the percentage of problems she got correct. It is important to note that if Emmy had answered any more or any less problems correctly, the percentage of correct answers would have been different. Therefore, it is important to understand the relationship between percentages and total number of problems answered correctly in order to accurately calculate the number of correct answers.
