Find the slope of the line on the graph.
Write your answer as a fraction or a whole
number, not a mixed number or decimal.

Answer:

[tex]y=\frac{1}{2}x-8[/tex]

Step-by-step explanation:

Perpendicular lines have the same slope. So, the slope of the line we need to find is 1/2.

Thus, the equation is

[tex]y+5=\frac{1}{2}(x-6) \\ \\ y+5=\frac{1}{2}x-3 \\ \\ y=\frac{1}{2}x-8[/tex]

Answer:

There are 13 small rooms and 9 large rooms reserved.

Step-by-step explanation:

First, we can make a system of equations. We can use s to represent the number of small rooms and l to represent the number of large rooms.

2 guests per small room added to 3 guests per large room equals 53 guests total, so 2s + 3l = 53.

The number of small rooms (s) plus the number of large rooms (l) equals the total number of rooms, so s + l = 22 or s = 22 - l.

We can substitute the first second equation into the first equation.

2 (22 - l) + 3l = 53

44 - 2l + 3l = 53

l = 9

So, the number of large rooms is 9. Then, to find the number of small rooms, we can substitute l into the second equation.

s = 22 - 9

s = 13

So, the number of small rooms is 13.

-1 39/45

that is the answer

The unit rate for this problem is how much Alyssa  earns per hour

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Alyssa works 6.4-hour shifts at the donut shop each day.

Last week she earned $480 for working 32 hours.

Now, To determine her earnings per hour we have to divide her total earnings by the total no. of hours she worked which is,

Given,

Anna desires to enroll in fitness courses. She contrasts two gyms to see which offers the best value. Each class at Fit Fast costs a specified amount. Stepping up costs a monthly fee as well as a price for each lesson.

We have to find the system of equations representing these costs;

Fit Fast: a certain number of feet per class = y = Ax

Stepping Up: a monthly charge plus a cost for each additional class = h = Bx + C

The second and fourth systems can be ignored since they lack the form that is implied by the statement.

Given that it reflects a choice that is always preferable to the alternative, the first system produces an obvious result. There is no need to compare because, for any positive value of x, 5.5x will be less than 7.5x + 10,

The third system is

It is necessary to solve the equations y = 7.5x and y = 5.5x + 10 to decide when one rate is more practical than the other.

The probability that she wins the next two matches is 36% or 0.36

How to calculate the probability of two matches?

Given,

She believes that the outcome of each match is independent. So, the outcome of next match does not depend on the previous match, is called independent event.

The probability of winning one match is 0.6

Since the outcome of each match is independent, we easily get the probability of she winning the next two matches by multiplying the probability of she winning per match. So,

Probability she wins the next two matches = 0.6 x 0.6

= 0.36 or 36%

Thus, the probability that she wins the next two matches is 36% or 0.36

Step-by-step explanation:

The values of x in the given equation are x = -9 and x = 3. The solution set is [-9, 3]

From the question, we are to determine the value of x in the given equation.

The given equation is

|x + 3|= 6

Then, we can write that

x + 3 = 6 and -(x + 3) = 6

Solving the first equation

x + 3 = 6

Subtract 3 from both sides of the equation

x + 3 - 3 = 6 - 3

x = 3

Solving the second equation

-(x + 3) = 6

-x - 3 = 6

Add 3 to both sides of the equation

-x - 3 + 3 = 6 + 3

-x = 9

Multiply both sides of the equation by -1

-1 × -x = -1 × 9

x = -9

Hence, the solutions are x = -9 and x = 3

Answer:

x = 30

y = 15

z = 150

Step-by-step explanation:

90°, 2x°, and x and supplementary.

Using this knowledge, we can form the equation:

2x° + 90° + x° = 180°

and solve for x.

3x°+ 90° = 180°

3x° = 90°

x° = 30°

x = 30

x and z are same side interior angles. Therefore, they are supplementary.

Using this knowledge, we can form the equation:

x° + z° = 180°

30° + z° = 180°

z° = 150°

z = 150

z° and 2y° are supplementary.

Using this knowledge, we can form the equation:

z° + 2y° = 180°

150° + 2y° = 180°

2y° = 30°

y° = 15°

The rate of the square increasing when the area is 16 cm² is 64 cm²/s. The result is obtained by using basic derivative rules.

The rate of a square increasing can be counted by the derivative of the area of the square as a function of time.

dA/dt = 2s ds/dt

Where s is side length.

If each side of a square is increasing at a rate of 8 cm/s, what is the rate of the square increasing when the area is 16 cm²?

We have the side of the square as the function of time.

ds/dt = 8 cm/s

When the area is 16 cm², the side length is

A = s²

16 = s²

s = √16

s = 4 cm

The rate of the square increasing is

dA/dt = 2s ds/dt

dA/dt = 2 × 4 × 8

dA/dt = 64 cm²/s

Hence, the rate of the square increasing when the area is 16 cm² is 64 cm²/s.

The 95% confidence interval for the true proportion of people who favored candidate a is 0.419, 0.481

How to calculate confidence interval?

First, calculate sample proportion by divide number people who favored candidate by number of sample. So:
[tex]\pi[/tex] = 450 / 1,000 = 0.45

Then we use the formula for confidence interval

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

In which z is z score that has a p value of [tex]1 - \frac{\alpha }{2}[/tex]

For 95% confidence interval z is the value of Z that has a p value of [tex]1 - \frac{0.05}{2}[/tex] = 0.975, so z = 1.96

After we have [tex]\pi[/tex] value and z value then put it in the formula. So:

= 0.45 ± [tex]1.96\sqrt{\frac{0.45(1-0.45)}{1000} }[/tex]

= 0.45 ± 0.0308

= 0.419, 0.481

Thus, the 95% confidence interval for the true proportion of people who favored candidate a is 0.419, 0.481

Answer:

To multiply terms containing exponents, the terms must have the same base and/or the same power. To multiply terms with the same base, keep the same base and add the powers together. To multiply terms with different bases but the same power, raise the product of the bases to the power.

Step-by-step explanation:

No, Is it not possible that creating a Boxplot could show outliers but z-scores show no outlier. This is because Any z-score that is either higher than +3 or lower than -3 is viewed as an issue.

When you declare a data point to be an outlier and reject it, you are indicating that even if you have already observed the point, it is unlikely to happen again.

Z scores make it easier to determine whether a data value is larger or less than the mean and how far from the mean it is. The Z score precisely indicates the number of standard deviations a data point deviates from the mean.

So, Outliers can be highlighted using scatterplots, histograms, and boxplots. Asterisks or other symbols are displayed on the graph in boxplots to plainly show the presence of outliers in a dataset.

Answer:

m∠1 = 88°

m∠2 = 42°

m∠3 = 113°

Step-by-step explanation:

All of the angles in a triangle add up to 180°. This knowledge can be used to find angle 3, which I will rename c to make writing an equation easier.

[tex]180=25+42+c\\180=67+c\\113=c[/tex]

Angle 3 is 113°

Two angles on either side of the intersection of two straight lines are equal, therefore angle 2, or b:

[tex]b=42[/tex]

Angle 2 is 42°

Now that two angles are known in the leftmost triangle, we can solve for the last one: Angle 1, or a:

[tex]180=50+42+a\\180=92+a\\88=a[/tex]

Angle 1 is 88°

What is function?  

    A function is a procedure or a relation that links each element of a non-empty set A, at least one element of another non-empty set B, to another element of the first non-empty set A. In mathematics, a function is defined as a relation f between a set A (the function's domain) and a set B (its co-domain). For any a A and b B, f = (a,b)| .Every element of set A must have exactly one image in set B for a relation to be considered a function. A relation from a non-empty set B is called a function if it has the property that no two separate ordered pairs in f have the same first element.

Here the given height h(t) = 100 feet

Now the given function is,

=> h(t)=25[tex]t^2[/tex]-81 .

Put h(t)=100 then ,
