Geometry test, you only have to put the correct letter don’t worry about typing out the whole answer

Answer:

B

Step-by-step explanation:

Permieter = 2(l + w)

200ft = 2(l + w)

l = 4 + 2w

200ft = 2(4  + 2w + w)

200ft = 2(4 + 3w)

200ft = 8 + 6w

6w = 192ft

w = 32ft

l = 4 + 2(32ft)

= 4 + 64ft

= 68ft

So the answer is B

Based on the hypothesis test conducted at the 0.10 level of significance with information gathered from 290 voters, the mayor decides to reject the null hypothesis. Therefore, there is sufficient evidence at the 0.10 level to support the mayor's claim that under 74% of the residents favor construction of the adjoining bridge.

To assess the mayor's claim, a hypothesis test is conducted. The null hypothesis (H0) assumes that the percentage of residents favoring the construction is equal to or greater than 74%. The alternative hypothesis (Ha) suggests that the percentage is under 74%.

By gathering information from 290 voters, data is analyzed to determine if there is enough evidence to reject the null hypothesis. The significance level is set at 0.10, meaning that if the p-value (probability value) obtained from the test is less than 0.10, the null hypothesis is rejected.

Since the mayor decides to reject the null hypothesis at the 0.10 level, it implies that the p-value is less than 0.10. This indicates that there is sufficient evidence to support the mayor's claim that under 74% of the residents favor construction of the adjoining bridge.

In conclusion, based on the hypothesis test and the decision to reject the null hypothesis, the evidence suggests that the percentage of residents supporting the construction is indeed under 74%, supporting the mayor's claim.

The system that is represented by the graph is inequality 3

What is system of inequalities?

A group of two or more inequalities in one or more variables is referred to as a system of inequalities. When a problem requires a variety of solutions and those solutions must satisfy multiple constraints, systems of inequalities are used.

We are given the graph of inequalities and given 4 choices out which 1 is the correction representation of the inequalities given in the graph

Now As you  can see one the parabolas open downwards that means the term x^2 is negative in that case where as the other parabola opens upwards hence the term x^2 is positive.

So second and third options are the options which satisfies this criteria

if we put x = 0 in the second equation of both the inequalities we get y= 4

This criteria is satisfied by only inequality 3 hence the correct system of inequality is inequality 3

Step-by-step explanation:

The volume of the rectangular pyramid is 84 cubic inches.

Since the rectangular prism has a volume of 252 in.3 and is rectangular, we know that its volume can be calculated as length x width x height. Let's call the length, width, and height of the rectangular prism "l", "w", and "h", respectively.

So, we have:

l x w x h = 252 in.3

Now, we know that the rectangular pyramid has a base and height that are congruent to the prism. This means that the base of the pyramid is also a rectangular shape with length "l" and width "w", and the height of the pyramid is also "h".

The formula for the volume of a rectangular pyramid is:

(1/3) x base area x height

Since the base of the pyramid is congruent to the base of the prism, the base area of the pyramid is also l x w. So, we can substitute these values into the formula:

(1/3) x (l x w) x h

Simplifying:

(1/3) x lwh

We already know that we = 252 in.3, so we can substitute that in:

(1/3) x 252 in.3

Simplifying:

84 in.3

Therefore, the volume of the rectangular pyramid is 84 in.3.

What is speed?

Velocity is defined as the speed of movement of an object along its direction. Velocity tells you how fast an object is moving and the direction it's moving. Similar to velocity, but also adds direction. Therefore, velocity is directed velocity, although velocity has no direction.

how to calculate speed

Find the initial velocity of an object by dividing the time it took the object to travel the specified distance by the total distance. In the formula V = d/t, V is velocity, d is distance, and t is time.

  circumcenter

Step-by-step explanation:

You want to know the name of the point equidistant from the vertices of a triangle.

The circle that passes through the vertices of a triangle is called a "circumcircle". It circumscribes the triangle. Its center is equidistant from all points on the circle, so is equidistant from the triangle's vertices.

The point equidistant from the vertices of a triangle is the circumcenter.

The probability of this event is 3/13. The event described is choosing a red card with an even number from a deck. To express this event as a set, we will include all even-numbered cards from the red suits (diamonds and hearts). This set is: {2♦, 4♦, 6♦, 8♦, 10♦, 2♥, 4♥, 6♥, 8♥, 10♥}.

Now let's find the probability of this event. There are 52 cards in the deck and 10 cards in the event set. Therefore, the probability is:

P(event) = (number of favorable outcomes) / (total number of outcomes) = 10 / 52 = 5 / 26 ≈ 0.1923

The probability of choosing a red card with an even number from a deck is approximately 0.1923 or 19.23%.

What is a polynomial?

A polynomial is a mathematical expression consisting of variables (also known as indeterminates) and coefficients, combined using addition, subtraction, and multiplication operations. The variables in a polynomial are raised to non-negative integer powers.

To find the values of "m" for which the function \(y = x^{m}\) is a solution of the given differential equation \(x^{2} y - 5xy' + 8y =0\) we need to substitute \(y = x^{m}\)  into the equation and see which values of "m" satisfy it.

\(x^{2} (x^{m} )- 5xx^{m}' + 8x^{m} = 0\)

\(x^{m+2} - 5(x^{m+1} ) + 8x^{m} = 0\)

Now, we can divide the equation by \(x^{m}\) assuming x not equal to 0

\(x^{2} - 5x + 8 = 0\)

This is a quadratic equation, and we can solve it using the quadratic formula:

\(x=-b+-\sqrt{b^{2}-4ac }/2a\)

For this equation, a=1, b=-5, c=8  Plugging these values into the quadratic formula, we get:

\(x=-5+-\sqrt{25-4*1*5}/2*1\)

\(x=5+-\sqrt{-7}/2\)

Since we have a negative value inside the square root, the quadratic equation has no real solutions. This means there are no values of "m" for which \(y=x^{m}\) is a solution of the given differential equation.

Therefore, none of the given answer choices (2 and 4, -2 and -4, 3 and 5, 2 and 3, 1 and 5) are correct.

$21.25÷$4.25=5

Answer:

Step-by-step explanation:

The strength of a linear relationship between two variables is typically measured by the correlation coefficient (r) or the coefficient of determination (r^2). A value of r or r^2 closer to 1 indicates a stronger positive linear relationship, whereas a value closer to -1 indicates a stronger negative linear relationship. A value of r or r^2 closer to 0 indicates a weaker or no linear relationship.

Looking at the given regression equations and their correlation coefficients, the regression with the weakest linear relationship between x and y is Regression 3:

Regression 1: y = -5.8x - 6.5, r = -0.7621

Regression 2: y = 2.4x - 14.7, r = 0.809

Regression 3: y = -7.4x - 17.4, r = -0.233

Regression 4: y = -3.4x - 8.5, r = -0.6121

Regression 3 has the lowest absolute value of r (0.233), indicating the weakest or no linear relationship between x and y. Therefore, Regression 3 represents the weakest linear relationship between x and y among the given options.

V₂ = 1.0 L

Step-by-step explanation:

Combined Gas Law

\(\sf \dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}\)

where:

Temperature must be in kelvins (K).

To convert Celsius to kelvins, add 273.15.

Volume can be in any unit.

Given values:

Rearrange the equation to isolate V₂:

\(\implies \sf V_2=\dfrac{P_1V_1T_2}{P_2T_1}\)

Substitute the given values into the equation:

\(\sf \implies V_2=\dfrac{5 \cdot 1 \cdot 600}{10 \cdot 300}\)

\(\sf \implies V_2=\dfrac{3000}{3000}\)

The solution to the system is (x,y) = (48,19).

To find the solutions to the system of equations, we need to find the values of x and y that satisfy both equations simultaneously. One way to do this is to set the two expressions for y equal to each other and solve for x:

2/3x−5 = 1/2x+3

Multiplying both sides by 6 (the least common multiple of 3 and 2) to clear the fractions, we get:

4x - 30 = 3x + 18

Simplifying, we get:

x = 48

Now that we know x, we can substitute it into either of the original equations to find the corresponding value of y. Let's use the first equation:

y = 2/3(48) - 5 = 19

So the solution to the system is (x,y) = (48,19).
