Answers

Answer:

m∠1 + m∠3 = m∠2 + m∠4

Step-by-step explanation:

In the figure attached,

In the given trapezoid if two sides AB and CD are parallel and AD is a transverse,

m∠1 + m∠3 = 180°

Similarly, if AB and CD are parallel and BC is a transverse,

m∠2 + m∠4 = 180°

Therefore, m∠1 + m∠3 = m∠2 + m∠4 is the relation between these angles.

A total of 360 people were surveyed. Of the people surveyed, 70 said they were an early bird and preferred tea. The percentage of people surveyed who are night owls is ___%. The percentage of early birds who prefer to drink tea is ___%.

Answers

Answer:

A total of  

360

people were surveyed. Of the people surveyed,  

70

said they were an early bird and preferred tea. The percentage of people surveyed who are night owls is  

60

%. The percentage of early birds who prefer to drink tea is  

49

%.

Step-by-step explanation:

The last row and the last column give the total number of people surveyed, which is 360.

The joint frequency of the Early Bird column and the Tea row show that 70 people said they were an early bird and preferred tea.

To get the percentage of night owls, divide the total number of night owls by the total number of people surveyed and multiply by 100:

To get the percentage of early bird tea drinkers, divide the joint frequency of early birds and tea by the marginal total number of early birds and multiply by 100:

From total of 360 people surveyed, 70 people are early birds and preferred tea. Hence night owls is 60% and people who prefer to drink tea is 49%

What is a survey?

A survey is a method of data collection and can be in the form of questionnaires and interviews. The survey tells us about the demands and needs of the people.

As per the question, the last row and column give us a total of 360. Those who are early birds and take tea are 70% of the population. To get the percentage we need to X night owls by the number of people surveyed multiplied by 100.

For the early bird tea, the total frequency of early birds by the marginal total number of early birds multiplied by 100.

support your conclusion.
HELP PLEASE

Answers

Answer/Step-by-step explanation:

The equation, [tex] \frac{20}{x} = -5 [/tex] has one solution, x.

The value of x that will make the equation true, that is the number we can substitute for x into the equation that will make what we have on our left side equal to what we have on our right side is -4.

Substitute -4 for x in the equation and simplify:

[tex] \frac{20}{-4} = -5 [/tex].

Simplifying the equation:

[tex] -5 = -5 [/tex] (this is true).

A value of x that can make the equation false is 4.

Thus, replace x with 4, then simplify.

[tex] \frac{20}{x} = -5 [/tex]

[tex] \frac{20}{4} = -5 [/tex]

[tex] 5 = -5 [/tex] (false. 5 ≠ -5)

Write an equation of the parabola in vertex form.

Answers

Answer:

f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. ... When written in "vertex form": • (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.

Answer:

y =0.25(x-4 )^{2}-1

Step-by-step explanation:

The formula of vertex form is as follows:

Y = a(x-h)^2+k

h = the x value for the vertex (in this case it is 4)

k = the y value for the vertex (in this case it is -1)

If you input these into the equation you are left with:

Y = a(x-4)^2-1

To find 'a' I just entered this equation into the Desmos calculator and messed around with the value until the y-intercept was (8,3)

Choose which property of equality is demonstrated moving from step a to step b. a. If b = 3, and m = 5, and y = mx + b then, b. y = 5x + 3

Answer:

Step-by-step explanation:

The property of equality is demonstrated moving from step a to step b is linear.

What is a linear equation?

The linear equation is defined as the equation having a degree of one or the power of the variable will be one. The linear equation is represented by y = mx + c. Here y is the variable, m is the slope and, c is the intercept.

Given that  b = 3, and m = 5, and y = mx + b then, b. y = 5x + 3. The equation can be formed as below:-

y = mx + c

y = 5x + 3

Therefore, the property of equality is demonstrated moving from step a to step b is linear.

Function h is a transformation of the parent exponential function, f(x)=2^x. h(x)=-3*2^x Which statement is true?

A. Function h is a vertical translation of function f. B. Function h is a reflection and a dilation of function f. C. Function h is a reflection and a translation of function f. D. Function h is a horizontal translation of function f.

Answers

Answer:

Function is a reflection and dilation of function f.

Step-by-step explanation:

A reflection gives the mirror image of function.

A function can be reflected about an axis by multiplying by -1.

To reflect function about the x-axis, multiply f(x) by -1 to get -f(x).

The correct option is: B. Function h is a reflection and a dilation of function f.

-----------------------

The functions are:

[tex]f(x) = 2^x[/tex]

[tex]g(x) = -3 \times 2^x[/tex]

It can be seed that g is f multiplied by -3.

The multiplication by a constant means that a dilation happened.Since the constant is negative, it means that a reflection also happened.

In the image at the end of this question, it can be seen that the g, the blue graph, is a reflected and dilated version of f, the red graph.

Thus, the correct answer is:

B. Function h is a reflection and a dilation of function f.
