Given:

Markers are sold in packages of 12 and pens are sold in packages of 8.

To find:

Least amount of markers and pens Rick needs to buy to have an equal number of markers and pens

Solution:

To find the least amount of markers and pens, we need to find the LCM of 12 and 8.

Prime factors of 8 and 12 are

\(8=2\times 2\times 2\)

\(12=2\times 2\times 3\)

To find the LCM, multiply all factors but the common factors are included only once.

\(LCM(8,12)=2\times 2\times 2\times 3\)

\(LCM(8,12)=24\)

Therefore, the least amount of markers and pens Rick needs to buy to have an equal number of markers and pens is 24.

Answer:

Not similar because of different interior angles

Step-by-step explanation:

For triangle XYZ:

z + 55 + 84 = 180

z + 139 = 180

z = 180 - 139

z = 41

For triangle PQR:

q + 55 + 38 = 180

q + 93 = 180

q = 180 - 93

q = 87

Since the interior angles of the 2 triangles aren't equal, they are not similar

Answer:

14 is the correct answer. It is just the inverse of 5+9 but it equals the same

Step-by-step explanation:

The regression equation, denoted as y, can be used to analyze a data set representing a progression of hourly temperature measurements.

Regression analysis is a statistical technique used to model the relationship between variables. In this case, the data set consists of hourly temperature measurements, and the regression equation (y) can be employed to analyze this progression.

The regression equation, typically represented as y = a + bx, allows us to estimate the dependent variable (y) based on the independent variable (x). In the context of temperature measurements, x could represent time or any other relevant factor influencing temperature changes.

By fitting the data to the regression equation, we can determine the values of the coefficients a and b, which represent the intercept and slope, respectively. These coefficients provide insights into the relationship between time (or other factors) and the temperature progression.

The regression analysis helps to quantify and understand how temperature varies over time, allowing for predictions and analysis of trends. It is important to note that the interpretation of the regression equation's coefficients should be done with caution and consideration of the specific context and nature of the data.

A vector field is conservative if its curl is zero. The curl of the vector field F is zero, so F is conservative. The scalar potential of F is given by: f(x, y, z) = x^3 + 2xyz + z^4/4 + C. The work done in moving an object in this field from (1, -2, 1) to (3, 1, 4) is: W = f(3, 1, 4) - f(1, -2, 1) = 70

A vector field is conservative if its curl is zero. The curl of a vector field is a vector that describes how the vector field rotates. If the curl of a vector field is zero, then the vector field does not rotate, and it is said to be conservative.

The curl of the vector field F is given by: curl(F) = (3z^2 - 2y)i + (2x - 3z)j

The curl of F is zero, so F is conservative.

The scalar potential of a conservative vector field is a scalar function that has the property that its gradient is equal to the vector field. In other words, F = ∇f.

The scalar potential of F is given by:

f(x, y, z) = x^3 + 2xyz + z^4/4 + C

The work done in moving an object in a conservative field from one point to another is equal to the change in the scalar potential between the two points. In this case, the work done in moving an object from (1, -2, 1) to (3, 1, 4) is:

W = f(3, 1, 4) - f(1, -2, 1) = 70

The question is:

This means it is required to find the z-score for 0.05.

To do this, you have to refer to the Area Under Normal Distribution Table.

z-scores are given along the 1st column and 1st row.

The value 0.05 is the significance level. We have to find its corresponding confidence level. To do that, subtract from 0.5:

The z-score for 0.45 is the same as the z-score for 0.05.

Check this or its approximate value in the table:

You'll see for 0.4495.

This falls on 1.6 under .04

Add them together to get 1.6+0.04=1.64

The z-score is 1.64.

The slope of the line shown in the graph is __2/3__

and the y-intercept of the line is __6___

The general linear equation is written as follows:

y = ax + b

Where a is the slope and b is the y-intercept.

On the graph we can see that the y-intercept is y = 6, then we can write the line as:

y = ax + 6

The line also passes through the point (-9, 0), replacing these values in the line we will get:

0 = a*-9 + 6

9a = 6

a = 6/9

a = 2/3

That is the slope.

In this problem, we are dealing with a random variable related to people's opinions on a new building project. We are given four options for the correct wording of the random variable and need to determine the correct one. Additionally, we are asked to calculate probabilities associated with the number of people who favor the new building project, ranging from exactly 4 to at most 6.

a) The correct wording for the random variable is "rv = the number of people who are in favor of a new building project." This wording accurately represents the random variable as the count of individuals who support the project.

b) To calculate the probability that exactly 4 people favor the new building project, we need to use the binomial probability formula. Assuming the probability of a person favoring the project is p, we can calculate P(X = 4) = (number of ways to choose 4 out of 10) * (p^4) * ((1-p)^(10-4)). The value of p is not given in the problem, so this calculation requires additional information.

c) To find the probability that less than 4 people favor the new building project, we can calculate P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3). Again, the value of p is needed to perform the calculations.

d) The probability that more than 4 people favor the new building project can be calculated as P(X > 4) = 1 - P(X ≤ 4) = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)).

e) The probability that exactly 6 people favor the new building project can be calculated as P(X = 6) using the binomial probability formula.

f) To find the probability that at least 6 people favor the new building project, we can calculate P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10).

g) Finally, to determine the probability that at most 6 people favor the new building project, we can calculate P(X ≤ 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6).

Answer:

The watch is cheaper in Geneva, Switzerland by a value of £20

Step-by-step explanation:

To get the city in which the watch is cheaper, what we need to do is to express the price of the watch in the same currency.

Since pounds is also used in the b part of the question, it would be easier working with it.

In Geneva, the price of the watch is 193.75 CHF

from our conversion formula;

£1 = 1.55 CHF

£x = 193.75 CHF

We cross multiply to get the value of x

(193.75 * 1)/1.55

= 193.75/1.55 = £125

We can see that the watch costs less in Geneva and higher in Manchester

By how much is it cheaper?

We can calculate this by subtracting the value in Geneva from the value in Manchester

That would be 145-125 = £20 cheaper

Link 2 is rotated clockwise and counterclockwise, it will not move or rotate as there are no degrees of freedom and the linkage is constrained.

Given: Number of full joints = 3 Number of half joints = 0Mobility = 1 Degrees of freedom = 1

As we know that the formula for calculating mobility is given by, Mobility = 3 (n - 1) - 2j Where, n = number of linksj = number of full joints

Substituting the given values, Mobility = 3 (n - 1) - 2j1 = 3 (n - 1) - 2(3)1 = 3n - 3 - 63 = 3n - 9n = 4 Degrees of freedom = (number of links - 1) - 2(number of full joints) + (number of half joints)

Substituting the given values,Degrees of freedom = (4 - 1) - 2(3) + (0) Degrees of freedom = -1

Therefore, there are no degrees of freedom. As there are no half joints in the given linkages, the given linkage is a constrained linkage.

Therefore, when Link 2 is rotated clockwise and counterclockwise, it will not move or rotate as there are no degrees of freedom and the linkage is constrained.

Step-by-step explanation:

the answer to what question ?

is the request to find (solve for) x ?

if so, we have

(-3(2x - 6) + 5x)/6 = 7 + (2(-4x + 1) - 6)/3

now, I usually remove the fractions first by multiplying both sides with both denominators :

1. multiply by 6

-3(2x - 6) + 5x = 42 + 6(2(-4x + 1) - 6)/3

2. I can skip the general multiplication by 3, because the denominator 3 goes away in interaction with the new factor 6

-3(2x - 6) + 5x = 42 + 2(2(-4x + 1) - 6)

now, we do all the multiplications and see what we get :

-6x + 18 + 5x = 42 + 2(-8x + 2 - 6) =

= 42 - 16x + 4 - 12

-x + 18 = -16x + 34

\(h(x)=\frac{1}{5}x\)

Step-by-step explanation:

\(6x+y=4x+11y\\\\6x-4x=11y-y\\\\2x=10y\\\\y=\frac{2x}{10}\\\\y=\frac{1}{5}x\)

so h(x) is

\(h(x)=\frac{1}{5}x\)

The value of r'(1) is 112.

To find the derivative of r(x) at x = 1, we'll use the chain rule. The chain rule states that if r(x) = f(g(h(x))), then the derivative of r(x) with respect to x is given by r'(x) = f'(g(h(x))) * g'(h(x)) * h'(x).

When r(x) = f(g(h(x))) by chain rule

r'(x) = f'(g(h(x))) * g'(h(x)) * h'(x)

So r'(1) =  f'(g(h(1))) * g'(h(1)) * h'(x)

As h(1) = 2 and h'(1) = 4

r'(1) = f'(g(2)) * g'(2) * 4

As g(2) = 4 and g'(2) = 4

r'(1) = f'(4) * 4 * 4

As f'(4) = 7

r'(1) = 7 * 4 * 4

r'(1) = 112
