What is the area of this figure?

The statement which is true about the slope of the given graphed line is that the slope is positive.

Slope is the proportion of decrease or increase in variable y due to increase and decrease in variable x. The formula of calculating slope is as under:

Slope=[tex](y_{2} -y_{1}) /(x_{2} -x_{1})[/tex]

We have to find the slope of the graphed line and for that we have to first take two points which lie on the line whose slope we have to find.

Take the points (0,4) and (-5,2) and calculating slope we get:

slope=(2-4)/(-5-0)

=-2/-5

=2/5

Hence the statement which is true is that the slope is positive.

Answer:

m<VRU = 80°

m<URW = 15°

Step-by-step explanation:

<SRW and <VRT are vertical opposite angles. Vertical opposite angles are equal. Therefore:

[tex] 2x + 15 = 85 [/tex]

Use this expression to solve for the value of x

[tex] 2x + 15 - 15 = 85 - 15 [/tex]

[tex] 2x = 70 [/tex]

[tex] \frac{2x}{2} = \frac{70}{2} [/tex]

[tex] x = 35 [/tex]

Find m<VRU by plugging in the value of x in the expression for its angle given.

m<VRU = [tex] 2x + 10 [tex]

[tex] 2(35) + 10 = 70 + 10 = 80 [tex]

m<VRU = 80°

FIND m<URW.

m<URW = 180° - (m<VRU + m<SRW) (angles on a straight line is 180°)

m<URW = 180 - (80 + 85)

= 180 - 165

m<URW = 15°

Dance instructor can chose 4 students out of 10 if order doesn't matter in 210 ways

A combination is a selection of all or part of a set of objects, without regard to the order in which objects are selected.

For example, suppose we have a set of three letters: A, B, and C. We might ask how many ways we can select 2 letters from that set. Each possible selection would be an example of a combination.

Formula of combination:

[tex]C_{n} ^{r} = \frac{n!}{r! (n-r)!}[/tex]

Where

nCr is   the selection of objects from a group of objects where order of objects does not matter.

n is the total number of objects

r is the number of selected objects.

According to the question

A dance instructor chose four of his 10 students to be on stage for a performance and order does not matter .

i.e,

if we have to chose and order does not matter that means we have to use combination .

[tex]C_{n} ^{r} = \frac{n!}{r! (n-r)!}[/tex]

Total number of students (n)= 10

Number of selected students (r) = 4

[tex]C_{n} ^{r} = \frac{n!}{r! (n-r)!}[/tex]

[tex]C_{n} ^{r} = \frac{10!}{4! (6)!}[/tex]

[tex]C_{n} ^{r} = \frac{10*9*8*7}{4*3*2*1 }[/tex]

[tex]C_{n} ^{r} = \frac{5040}{24 }\\[/tex]

[tex]C_{n} ^{r} = 210[/tex]

Hence, Dance instructor can chose 4 students out of 10 in 210 ways

Answer:

2x

Step-by-step explanation:

Factor both terms given to simplest terms:

8x = 2 * 2 * 2 * x

22xy = 2 * 11 * x * y

Note that in each case, there is the factor of 2 & x that is shared by both. These are what is used to find the Greatest Common Factor. Multiply both terms together:

2 * x = 2x

2x is your GCF.

~

First find the greatest common factor of 8 and 22.

To find the greatest common factor of 8,

begin by dividing 8 by all the numbers you can.

8 ÷ 1 = 8

8 ÷ 2 = 4

Notice that I stopped here because if I continued

dividing, I would be dividing 8 by 4 which is 2.

Make sure to stop dividing when you see numbers repeat.

So the factors of 8 are 1, 2, 4, and 8.

Now do the same thing for 22.

22 ÷ 1 = 22

22 ÷ 11 = 2

So the factors of 22 are 1, 2, 11, and 22.

Now look for the largest number shared by the two lists.

In this case, the largest number is 2.

Now let's move to the variables.

To qualify for the Greatest Common Factor,

the variable must appear in every monomial.

Since the y doesn't appear in every monomial, it doesn't qualify.

However, notice that the x does appear in every monomial.

If the variable does appear in every monomial, the Greatest

Common Factor will use the smallest power on that variable.

Since the smallest power for x in both monomials is x, we use x.

So our greatest common factor is 2x.

h= number of hours

m= number of miles

Formula: 4h=12m

(4 hours equals 12 miles)

Divide 4 on each side.

h= 3m

3 miles per hour.

Then, convert miles to feet. And hours to minute.

To do this simultaneously,

Convert miles to feet and hours to minutes.

There should be 3 "fractions" to multiply.

The first should be the original problem:

3miles/1 hour. (3 miles per hour).

The second should be 1 hour/60min. (1 hour per 60 min).

The third should be 5280 ft/1 mile. (5280 feet per mile).

The second and the third fractions are to convert miles to feet and the hours to minutes.

Answer:

Total Earnings = 18,160

1) 1.07 * principal1 *  + 1.06  * principal2= 18,160

2) principal1 + principal2 = 17,000

We'll multiply equation 2) by -1.06

2) -1.06*principal1 -1.06*principal2 = -18,020 then adding equation 1)

1) 1.07 * principal1 *  + 1.06  * principal2= 18,160

Answer:

x = -9

Step-by-step explanation:

To solve these types of questions,

a). If both the sides of the equation are different,

    2x + 3 = 3x - 6

   There will be exactly one solution.

b). If the coefficient of variable 'x' is same in both the sides of the equation,

    x - 3 = x - 6

    Solution set will be 'none'.

c). If both the sides of the equation are exactly same then equation will have infinite solutions.

   2x + 3 = x + x + 3

In the given equation,

6x - (5x + 5) = -8 - 2(x + 12)

Further simplify the equation,

(6x - 5x) - 5 = - 8 - 2x - 24

x - 5 = -2x - 32

x + 2x = 5 - 32

3x = -27

x = -9

Answer:

It should be noted that the p.f of X and Y when they are independent can be obtained by multiplying together their marginal probability function.

Step-by-step explanation:

Two discrete random variables X and Y are said to be statistically independent if and only if , for all possible values ( xi, yi) the joint probability function f(x,y) can be expressed as the product of two marginal functions. That is X and y are independent if

f(x,y) = P(x=xi  and Y =yi)

          =  P(x=xi) P(Y =yi)         for all i and j

            = g(x)h(y)

It should be noted that the p.f of X and Y when they are independent can be obtained by multiplying together their marginal probability function.

The values of marginal probabilities are often written in the margins of the joint table as there are rows and columns totals in the table. The probabilities in each marginal probability function add to 1.

Step-by-step explanation:

Represent the equation as follows:

[tex]a * b = c[/tex]

Where a,b and c are decimal numbers

To solve further, we make use of trial by error method

Let

[tex]a = 2.52[/tex]

[tex]b = 0.6[/tex]

Such that

[tex]2.5 * 0.6 = c[/tex]

[tex]1.512 = c[/tex]

[tex]c = 1.512[/tex]

This set of digits do not follow the rule in the question

Let

[tex]a = 2.55[/tex]

[tex]b = 1.6[/tex]

[tex]2.55 * 1.6 = c[/tex]

[tex]4.08 = c[/tex]

[tex]c = 4.08[/tex]

The result has only 2 non zeros (4 and 8)

Hence

[tex]2.55 * 1.6 = 4.08[/tex] answers the question.

However, there are other set of numbers that can be used too

One of the equation which illustrates and meets the conditions given is :

First number, x = 1.25

First number, x = 1.25 Second number, y = 0.2

Result = first Number × second number

Result = 1.25 × 0.2

Result = 1.25 × 0.2 Result = 0.25

Evaluating the result : 0.25

Number of digits = 3

Non - zero digits = 2

There are several values of x and y which will satisfy the 3 conditions given.

Therefore, the product of the values 1.25 and 0.2 gives the required output.
