Answer:

The values are:

Step-by-step explanation:

Given:

To Determine:

a = ?

b = ?

c = ?

Determining the values of a, b, and c

Using the mid-point formula

\(m\:=\:\left(\frac{x_1+x_2}{2},\:\frac{y_1+y_2}{2},\:\frac{z_1+z_2}{2}\right)\)

Using the mid-point formula

\(m\:=\:\left(\frac{x_1+x_2}{2},\:\frac{y_1+y_2}{2},\:\frac{z_1+z_2}{2}\right)\)

given

(x₁, y₁, z₁) = (1, 2, b) = P

(x₂, y₂, z₂) = (c, -7, 4) = Q

m = (x, y, z) = (-3, a, -1) = R

substituting the value of (x₁, y₁, z₁) = (1, 2, b) = P,   (x₂, y₂, z₂) = (c, -7, 4) = Q, and m = (x, y, z) = (-3, a, -1) = R in the mid-point formula

\(m\:=\:\left(\frac{x_1+x_2}{2},\:\frac{y_1+y_2}{2},\:\frac{z_1+z_2}{2}\right)\)

\(\left(x,\:y,\:z\right)\:=\:\left(\frac{1+c}{2},\:\frac{2+\left(-7\right)}{2},\:\frac{b+4}{2}\right)\)

as (x, y, z) = (-3, a, -1), so

\(\left(-3,\:a,\:-1\right)\:=\:\left(\frac{1+c}{2},\:\frac{2+\left(-7\right)}{2},\:\frac{b+4}{2}\right)\)

Determining 'c'

-3 = (1+c) / (2)

-3 × 2 = 1+c

\(1+c = -6\)

\(c = -6 - 1\)

\(c = -7\)

Determining 'a'

a = (2+(-7)) / 2

\(2a = 2-7\)

\(2a = -5\)

\(a = -5/2\)

Determining 'b'

-1 = (b+4) / 2

\(-2 = b+4\)

\(b = -2-4\)

\(b = -6\)

Therefore, the values are:

\(\overline{A}\)  = {0, 1, 4, 5, 6, 7, 8}, \(\overline{B}\) =  {2, 4, 7, 9}, A ∪ B =  {0, 1, 2, 3, 4, 5, 6, 8, 9} and

A ∩ B = {3}.

A set is a collection of well-defined objects.

A subset contains all the elements or few elements of the given set.

The improper subset is when it contains all the elements of the given set and the proper subset is when it doesn't contain all the elements of the given set.

Given,

U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} is a universal set.

A = {2, 3, 9} and B = {0, 1, 3, 5, 6, 8}.

\(\overline{A}\) = (U - A) = {0, 1, 4, 5, 6, 7, 8}.

\(\overline{B}\)= (U - B) = {2, 4, 7, 9}.

A ∪ B = U - {7}.

A ∪ B =  {0, 1, 2, 3, 4, 5, 6, 8, 9}.

A ∩ B = {3}

Answer:

D. 36, 12

Step-by-step explanation:

Okay, so for the first part (how many total students are in Ms. Smith's class) all we need to do is count all the dots. So there's 5 in the none category, 6 in the one category, 1 in the two category, 6 in the three category, 8 in the four category, 5 in the five category, 2 in the six, 2 in the seven, and 1 in the nine, so we add all that up:

5 + 6 + 1 + 6 + 8 + 5 + 2 + 2 + 1 = 36

So there's 36 students total in Ms. Smith's class

Now we have to count how many students have less than 3 siblings, so we're going through the 0 - 2 categories:

5 + 6 + 1 = 12

So there's 12 students in Ms. Smith's class with less than 3 siblings

Step-by-step explanation:

Answer:

x=-4  and y=2  Those 2 equations when graphed give a vertical line and a horizontal line that intersect at the point (-4,2)

x+4=0 and y-2=0  are the same two lines.

or if you want more complicated systems of equations, with the same solution:

x+y=-2 and x-y=-6

in standard form, that's y=-x-2 and y=x+6  Graph those two lines and they intersect at (-4,2)

Those 2 lines are with slopes of -1 and +1.  Those 2 equations are a system of equations

whose solution is x=-4 and y=2.

Rotate two perpendicular lines around the point (-4,2) and you get more systems of  

equations with the same solution.

They don't have to be perpendicular though.  x+y=-2 and x=-4 are two lines forming

a 45 degree angle, with the same solution (-4,2)

They don't have to be linear either.  Take a parabola with the vertex (-4,2) and the line x=-4.

They intersect at the point (-4,2).  That parabola could be the simple y=x2 shifted up and

to the left, to y-2 = (x+4)2  or y=x2+8x+18   or it could be any one of a family of parabolas with

the same vertex.

You could have 2 circles tangent at the point (-4,2) Endless circles could have that point

as a tangent and their equations having that same solution (-4,2)

Answer:

Total Distance = 160 m

Average speed = 64 m/hr

Step-by-step explanation:

For first 2 hours:

Distance = Speed × Time

D = 70 × 2

D = 140 m

For the next half hour:

Distance = Speed × Time

Distance = 40 × 0.5

Distance = 20 m

Now total Distance:

Total Distance = 140+20

Total Distance = 160 m

After that,

Average Speed = Total Distance Covered/ Total Time taken

Average Speed = 160 m / 2.5 hours

Average speed = 64 m/hr

The solution to the inequality is x >= -2 for inequality 3x-5≥-11

Complete Question:

Suzette ran and biked for a total of 44.75 mi in 4 h. Her average running speed was 6.5 mph and

her average biking speed was 14 mph.

Let x = total hours Suzette ran. Let y = total hours Suzette biked.

a) Write the system of two equations you’ll need to solve this problem. (2 points)

b) Use substitution OR linear combination to solve for x and y. Show ALL of your work.

(4 points)

How many hours did Suzette run? ________ How many hours did she bike? _________

c) Check your work by using substitution

If Suzette ran and biked for a total of 44.75 mi in 4 h and her average running speed was 6.5 mph with average biking speed at 14 mph and average running speed at 6.5 mph, then she must have run 1.5hours and biked for 2.5 hours

Let x = total hours Suzette ran.

Let y = total hours Suzette biked

If the total hours biked is 4 hours, then:

x + y = 4 ....... 1

Also if her average running speed was 6.5 mph and her average biking speed was 14 mph with a total of 44.75 mi in 4 hours

6.5x + 14y = 44.75 ........ 2

From equation 1,

x = 4 - y ....... 3

Substitute the value of x into the equation 2 to have:

6.5x + 14y = 44.75

6.5(4 - y) + 14y = 44.75

26 - 6.5y + 14y = 44.75

 -6.5y + 14y = 44.75 - 26

7.5y = 18.75

Divide both sides by 7.5

7.5y/7.5 = 18.75/7.5

y = 2.5

This shows that Suzette biked 2.5hours

Substitute y = 2.5 into equation 1:

x + 2.5 = 4

x = 4 - 2.5

x = 1.5

This shows that Suzette ran for 1.5 hours

Hence if the average running speed was 6.5 mph and her average biking speed was 14 mph then she must have run 1.5hours and biked for 2.5 hours

The expression becomes: p^(1/2) = p^(1/2 * 1) = p^(1/2) Now we can simplify p^(1/2) as p^1/2 which equals the square root of p.

The property of exponents that must be applied to the expression p^(1/2) to derive p as the result is the Power of a Power Property.

The Power of a Power Property states that when a power is raised to another power, the exponents are multiplied.

For instance, consider the expression p^(1/2). We can apply the Power of a Power Property to this expression as follows: p^(1/2) = (p^(1/2))^1 By applying the Power of a Power Property, the exponent (1/2) is multiplied by the exponent 1, giving a result of 1/2.

Therefore, the expression becomes: p^(1/2) = p^(1/2 * 1) = p^(1/2)Now we can simplify p^(1/2) as p^1/2 which equals the square root of p.

So we have derived p as the result using the Power of a Power Property.

In summary, we must apply the Power of a Power Property to the expression p^(1/2) to derive p as the result.

The money loaned at 9% annual interest was 1500 and the money loaned at 11% annual interest was 19000.

Let the amount of money loaned at 9% be x

the amount of money loaned at 11% be y

According to the question,

Total money loaned = 20,500

Thus the equation formed is,

x + y = 20,500 ------ (i)

Simple interest is calculated by

I = P * r * t

where I is the simple interest

r is the rate of interest

t is the time

Thus, the interest on x = 0.09x

the interest on y = 0.11y

Total interest gained = 2,225

Thus the equation formed is,

For the given median, there are 50 students who scored greater than 72.

What is median?

The median is a measure of central tendency in a set of numerical data. It is the value that separates the higher half of the data from the lower half when the data is arranged in order from least to greatest or greatest to least.

We are given that 99 6th graders took a test and the median score was 72. We want to find out how many students scored greater than 72.

Let the scores be denoted by S1, S2, ..., S99. We can sort these scores in order from least to greatest:

S1 ≤ S2 ≤ ... ≤ S99

Since the median score is 72, exactly half of the scores are above 72 and half are below 72. Thus, the 50th score in the sorted list is 72.

Since there are 99 scores in total, we can approximate the number of students who scored above 72 by dividing the total number of students by 2:

\($\frac{99}{2} = 49.5$$\)

This means that approximately 49.5 students scored above 72.

Since 0.5 rounds up to 1, we round 49.5 up to 50. Therefore, approximately 50 students scored greater than 72.

The answer is C because 1 times 20 is 20 and .5 times 20 is 10 then you get 30

Answer: C.) $30.00

Step-by-step explanation: If 1.5 U.S. dollars equals 1 euro, then 1*20 would be 20 euros. So then, you could multiply 0.5*20 to get 10. Finally, you add $10 + $20 to get $30 U.S. dollars.

0.5*20= $10

20+10= $30

The equation for the line of best fit is: C. y = 0.894x + 0.535.

In order to determine the equation for the line of best fit, we would create a table of values based on the given x-values and y-values as follows;

x          y            x²        y²          xy__

5          4          25        16       20

6          6           36       36       36

9          9           81        81        81

10         11          100       121       110

14          12        196       144      168  

Sum                  438       398     415

Next, we would calculate the mean of the x and y variables as follows;

Mean = [∑(x)]/n

Mean = 44/5

Mean, \(\bar{x}\) = 8.8

Mean = [∑(y)]/n

Mean = 42/5

Mean, \(\bar{y}\) = 8.4

∑(x - \(\bar{x}\))(x - \(\bar{y}\)) = (5-8.8)(4-8.4) + (6-8.8)(6-8.4)+(9-8.8)(9-8.4)+(10-8.8)(11-8.4)+(14-8.8)(12-8.4)

∑(x - \(\bar{x}\))(x - \(\bar{y}\)) =45.4

∑(x - \(\bar{x}\))² = (5-8.8)²+(6-8.8)²+(9-8.8)²+(10-8.8)²+(14-8.8)²

∑(x - \(\bar{x}\))² = 50.8

Now, we can determine the slope coefficient for the line of best fit:

Slope (b) = 45.4/50.8

Slope (b) = 0.894.

Lastly, we would determine the intercept (a) as follows;

\(a = \bar{y} - b\bar{x}\)

a = 8.4 - (0.894)8.8

a = 0.535

Therefore, the required equation is y = 0.894x + 0.535.
