Z + 43 = a straight line which needs to equal 180 degrees.

Z = 180 - 43 = 137

answer: z = 137 degrees

Answer:

so we know that 43 and y are congruent so y = 43.

we also know that y + x has to equal 180

180 - 43 = 137

so x is 137. We also know that z and x are congruent, so therefore z is 137.

Step-by-step explanation:

To find the vertex from the given table look when the values of x or y start to switch the pattern. For example look at y value they get lower and lower 15,8,3,0,-1 then they get greater and greater 0, 3,8,15,24,...

So the he vertex is at (-2, -1) because here is where the pattern changed.

Y-intercept of the parabola is where the parabola intersects the y-axis so the x must be 0 there. Look in the table where is x=0 and see is at y=3.

Y-intercept point is at (0, 3)

X-intercept of the parabola is where the parabola intersects the x-axis so the y must be 0 there. Look in the table where is y = 0 and see is at x= -1 and also at x= -3.

X-intercept points are at (-1, 0) and (-3, 0)

Equation of the parabola in factored form is in general

y= (x- x intercept1)(x- x intercept 2), and for our problem is:

y = (x +1)(x +3)

The equation for the axis of symmetry is x = -2 because we have a vertical parabola (since x is squared in the equation) and the vertex is as we said previously at (-2, -1).

Graph the solution to the following system of inequalities. y > -2x+7, y ≤ 3x-8

Answers

The solution to the system of inequalities y > -2x+7, y ≤ 3x-8 is the set of points ( (x,y) pairs ) in the intersection of the regions these inequalities are true for, as shown in the graph by the intersection of the blue and red colors.

What are system of inequalities?

When mathematical expressions are compared, with non-strict equality, then such mathematical statements are called mathematical inequalties.

A collection of inequalities for which we consider common solution for all inequalities is called a system of inequalities.

How to draw regions covered by inequalities?

Suppose there is inequality given as: y ≥ f(x)

The region it covers is the region of value pairs (x,y) for which this inequality holds true.

We've to draw the region covered by it.

For a function y = f(x), there is y > f(x) on one side of the graph of the function y = f(x) in XY plane, and on other side there is y < f(x).

We just need to figure out this fact at 1 point on either side of the graph of the function y = f(x) , and then the area where y > f(x) is true, along with the curve of the function y = f(x) is included in the region covered by inequality y ≥ f(x)

For this case, the inequalities given are:

y > -2x+7, y ≤ 3x-8

Their solution is the points lying in the intersection of the regions these inequalities are true for, as shown in the graph by the intersection of the blue and red colors.

Eric and Erica have $5.40 between the two of them. If you double the amount of money Eric has and halve the amount Erica has, then they would have the same amount of money. How much money does Eric have?

Answers

Answer:

$1.08

Step-by-step explanation:

Use a system of equations. Let x represent eric's money and y represent erica's money.

x+y=5.40

2x=1/2y

Let's solve for y in the second equation and substitute it into the first.

Double both sides.

4x=y

Substitute

x+4x=5.40

5x=5.40

Divide by 5

x=$1.08

So eric has $1.08

A university class has 22 students: 3 are nursing majors, 9 are psychology majors, and 10 are business majors. (Each student has only one of these majors.) The professor is planning to select two of the students for a demonstration. The first student will be selected at random, and then the second student will be selected at random from the remaining students. What is the probability that the first student selected is a nursing major and the second student is a business major?

Answers

Answer:

27/462

.058

Step-by-step explanation:

the probability that the first student, selected at random, is a nursing student is 3/22.

the probability that the second student, selected at random from the remaining students, is an accounting major is 9/21.

the probability the first student chosen is a nursing student and the second student chosen is an accounting major is therefore 3/22 * 9/21 = 27/462.

A bakery sold 224 chocolate cupcakes in a day, which was 56% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?

Answers

Hence, 440 cupcakes were sold on that day.

The bakery sold a total of 400 cupcakes that day, with 224 of them being chocolate cupcakes, representing 56 precent of the total.

Use the concept of percentage defined as:

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred.

Given that,

A bakery sold 224 chocolate cupcakes in a day.

The 224 chocolate cupcakes represent 56% of the total number of cupcakes sold that day.

To find the total number of cupcakes sold,

Use the percentage given and some simple math.

If 56% of the cupcakes sold were chocolate cupcakes and that amounts to 224 cupcakes,

Set up the following equation:

0.56 x Total number of cupcakes = 224 cupcakes

To find the total number of cupcakes,

Divide both sides of the equation by 0.56:

Total number of cupcakes = 224 cupcakes / 0.56

Calculating this,

The bakery sold a total of 400 cupcakes that day.

A simple random sample of 100 8th graders at a large suburban middle school indicated that 83% of them are involved with some type of after school activity.

Answers

Using the z-distribution, as we are working with a proportion, the 99% confidence interval is given by:

a) (0.733, 0.927).

What is a confidence interval of proportions?

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.

In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

The other parameters are p = 0.83, n = 100, hence the bounds of the interval are given as follows.

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.83 - 2.575\sqrt{\frac{0.83(0.17)}{100}} = 0.733[/tex]

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.83 + 2.575\sqrt{\frac{0.83(0.17)}{100}} = 0.927[/tex]

Hence option a is correct.

Applying the chord theorem, since chords RS and TU are equal, then the measure of arc RS is: 106°.

What is the Chord Theorem?

The chord theorem states that if two chords in a circle are equal in length, then their corresponding minor arcs will also be equal in measure.

Since chords RS = TU, therefore:

m(RS) = m(TU)

Substitute

8x - 14 = 7x + 1

8x - 7x = 14 + 1

x = 15

m(RS) = 8x - 14

Plug in the value of x

m(RS) = 8(15) - 14

m(RS) = 106°
