You are in charge of getting food for the class from the corner store.  You can buy chips for $2 or a hoagie for $5.

There are 19 students in the class, so you need to buy at least 19 items, and you have $77 total.

Hence, the system of inequality to represent this situation is as follows:

let

x = number of chips

y = number of hoagies

Answer:

Volume of a cylinder (v) = πr²h

Step-by-step explanation:

Given V = 5m³

r = 0.7m and π = 3.14

h= ?

using V = πr²h

5 = 3.14 x 0.7² x h

5 = 3.14 x 0.49 xh

5= 1.5386h

divide both side by 1.5386

5/1.5386 = h

h= 3.24970

h= 3.25m ( nearest hundredth)

Answer:

  -(√2 +√6)/4

Step-by-step explanation:

You want the exact value of sin(17π/12).

The sine can be written as ...

  sin(17π/12) = sin(π +5/12π)

  = -sin(5/12π) = -sin(2/12π +3/12π)

  = -sin(π/6 +π/4)

  = -(sin(π/6)cos(π/4) +cos(π/6)sin(π/4))

  = -((1/2)(√2/2) +(√3/2)(√2/2))

  = -(√2 +√6)/4

The sine of 17π/12 is -(√2+√6)/4.

Note that assuming that the instrument used was exogenous, one can conclude about the endogeneity of an explanatory variable if the OLS and 2SLS estimates are significantly different: "The explanatory variable is endogenous and therefore 2SLS should be considered." (Option C)

Two-stage least squares (2SLS) regression analysis is a statistical approach used in structural equation analysis. The OLS approach has been extended using this methodology. It is employed when the error terms of the dependent variable are associated with the independent variables.

The ordinary least squares (OLS) approach is a linear regression methodology used to estimate a model's unknown parameters. The strategy is based on reducing the sum of squared residuals between the expected and actual values.

2SLS is utilized as an alternate strategy when we encounter endogeneity Problems in OLS. Endogeneity arises when the explanatory variable correlates with the error word. Then we utilize 2SLS, which employs an instrumental variable. The outcome will be different because if there is endogeneity in the model, OLS will produce biased results.

Full Question:
What can we conclude about the endogeneity of an explanatory variable if the OLS and 2SLS estimates are significantly different? Assume that the instrument used was exogenous. Select one:

a. The explanatory variable is not endogenous and therefore using 2SLS is ill-advised.

b. The explanatory variable is not endogenous and therefore OLS should not be used.

c. The explanatory variable is endogenous and therefore using 2SLS should be considered.

d. The explanatory variable is endogenous and therefore OLS should be used.

The value of angle 1 is 122°.

The value of angle 5 is 58°

The angle of angle 8 is 58°

The angle of angle 14 is 122°

The angle 18 is 58°

It should be noted that this information deals with angles. It should be noted that the value of angle on a straight line is 180°.

In this situation, the value of angle 1 will be:

= 180° - 58°

= 122°

Also it should be noted that vertically opposite angles are equal. Therefore, angle 5 will be 58°.

In this situation, it should also be noted that alternate angles are the same. Hence, Thai gives the value of the angles for angles 8, 14 and 18.

formula: y = mx + b

current points we know:

m = 1/2

x = 10

y = 0

so we solve for the b value.

0 = 1/2 (10) + b

0 = 5 + b

(inverse operation we subtracted 5 on both sides)

-5 = b

so the equation for a line with slope 1/2 passing through the point (10,0) is

y = (1/2)x + (-5) or y = (1/2)x - 5

Answer:B) -2x + 3y = 12 represents the graph.The y-intercept is 4, and the line intercepts the x-axis at -6. Therefore, the slope of the line is 4/6=2/3. The format for a linear equation is y=(slope)x+y intercept. So the equation would be y=2/3x+4. We can see that option B simplifies that. Adding 2x from both sides of the equation and we get 3y=2x+12. 

The expression represent a trinomial polynomial with three terms. The constant term is 1 , the leading term is 5, and the leading coefficient is 1 / 7.

A polynomial is defined as an expression which is composed of variables, constants and exponents, that are combined using operations such as addition, subtraction, multiplication and division.

Trinomials are the algebraic expressions with three unlike terms.  Trinomial has three terms.

A constant term is a term in an algebraic expression that does not contain any variables and therefore is constant.

The leading term is the term with the highest power of x.

The leading coefficient of a polynomial is the coefficient found with the variable that has the largest exponent.

Therefore, the expression is a trinomial polynomial. This means it has 3 terms.

The constant term of the polynomial is 1 ,

The leading term is 5, and the leading coefficient is 1 / 7.

Answer:

Step-by-step explanation: It looks like Leo is trying to prove that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles of the triangle. From the equations given, it seems that Leo is using the fact that the sum of the measures of supplementary angles is 180 degrees, and the sum of the measures of the angles of any triangle is 180 degrees, to try to prove his statement. Some equations that Leo could use to complete his argument might include:

x = p + q, which follows from the equation r + x = 180 and the substitution of p + q + r = 180

p + q = 180 - r, which follows from the equation p + q + r = 180 and the substitution of r + x = 180

x = p + q + 2r, which follows from the equation x + r = p + q + r and the substitution of r + x = 180

It's not clear from the information given whether these equations are sufficient to prove Leo's statement, as we don't have any information about the values of p, q, r, or x. However, these equations might be a good starting point for Leo to continue his argument.

All the 5 prizes are identical

We have to find out the number of ways in which the prizes can be awarded.

In this case, we have to use the combination formula to find the required answer.

Since the original radius of the circle was 8, the radius must be decreased to

Therefore, to decrease the area of the circle by $48\pi$, the radius must be decreased by a factor of about 1.1547.

Comparing both given functions, we can state that: B. Function 1 has the greater rate of change; the slope is 2.

Another name for the rate of change of a function is the slope. It is calculated using the formula:

Slope / rate of change = change in y / change in x.

If the equation of a linear function is given in slope-intercept form as y = mx + b, the rate of change or the slope is represented by "m".

Given the first function as an equation, y = 2x - 6, the slope of this function is represented as 2. This means, the rate of change is m = 2.

To find the rate of change of function 2, use two points from the table, (1, -4) and (2, -5):

Rate of change / slope (m) = (-5 - (-4)) / (2 - 1) = -1/1

m = -1.

The slope value of 2 is greater than the slope value of -1, therefore, we can conclude that: B. Function 1 has the greater rate of change; the slope is 2.

By using the squeeze theorem, we conclude that, [tex]$$\lim _{x \rightarrow a} f(x)=b .$$[/tex]

Limit of a function, Squeeze Law:

The squeeze theorem states that if f(x) ≤ g(x) ≤ h(x) for all numbers, and at some point x=k we have f(k)=h(k), then g(k) must also be equal to them. We can use the theorem to find tricky limits like sin(x)/x at x=0, by "squeezing" sin(x)/x between two nicer functions and ​using them to find the limit at x=0

We say that a function f(x) approaches a limit L approaches a, or, [tex]$\lim _{x \rightarrow a} f(x)=L$[/tex]

if, for every number [tex]$\epsilon > 0$[/tex], however small, such that [tex]$|f(x)-L| < \epsilon$[/tex],

there always exists a number δ>0 such that

[tex]|x-a| < \delta \text {. }[/tex]

The Squeeze Law:

Suppose that g(x) ≤ f(x) ≤h(x) in some neighborhood of a and also that

[tex]$$\lim _{x \rightarrow a} g(x)=L=\lim _{x \rightarrow a} h(x)$,[/tex]

then,

[tex]$$\lim _{x \rightarrow a} f(x)=L .$$[/tex]

We have to find the limit of f(x) as x approaches to x.

Let [tex]$b-|x-a|=g(x)$[/tex] and [tex]$b+|x-a|=h(x)$[/tex].

Then we have the inequality, g(x) ≤ f(x) ≤h(x)

Let us see what happens to g(x) and h(x) as [tex]$$x \rightarrow a$.[/tex]

[tex]$$\begin{aligned}g(x) & =b-|x-a| \\\\lim _{x \rightarrow a} g(x) & =\lim _{x \rightarrow a} b-|x-a| . \\& =b\end{aligned}$$[/tex]

Similarly,

[tex]$$\begin{aligned}h(x) & =b+|x-a| \\\lim _{x \rightarrow a} h(x) & =\lim _{x \rightarrow a} b+|x-a| . \\& =b\end{aligned}$$[/tex]

We have the conditions required by the Squeeze law,
