Answer:

  y = -10/3x -23

Step-by-step explanation:

The 2-point form of the equation of a line is useful for this.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

Using your points, we have ...

  y = (-3 -7)/(-6 -(-9))(x -(-9)) +7

  y = (-10/3)(x +9) +7

  y = -10/3x -23 . . . . . . . simplify

The equation of the line passing through the points (-9,7) and (-6, -3) is y = -10/3x -14.

In mathematics, the equation of a line can be given as y = mx + c, where m is the slope of the line and c is the y-intercept. Firstly, we need to calculate the slope (m) which is (y2 - y1) / (x2 - x1). If we substitute the points (-9,7) and (-6, -3) we get (-3 - 7) / (-6 + 9) = -10 / 3, so m = -10/3. Next, to get the y-intercept (c) we can substitute the slope and one of the points into the equation: 7 = -(10/3)*(-9) + c, and we get c = -14. Therefore the equation of the line is y = -10/3x -14.

The system of equations is solved by setting the two equations equal to each other and solving for x followed by solving for y using the obtained x value. The solution is x = -15.6 and y = 0.2.

The student is asking to solve a system of two linear equations:

To find the solution, we need to set the two equations equal to each other since they both equal y:

47 + 3x = 8 + 0.5x

Now, let's solve for x:

Now that we have x, we can solve for y using either of the original equations:

y = 8 + 0.5(-15.6)

Calculate y:

y = 8 - 7.8

y = 0.2

Therefore, the solution to the system of equations is x = -15.6 and y = 0.2.

Answer:

See Explanation Below

Step-by-step explanation:

Question is incomplete.

(The height of the prism is missing and no attachment is provide)

However, I'll solve on a general rule.

Given

Volume of prism, V = 294in³

The volume of a prism is calculated multiplying the base area by the height of the prism.

Let's represent the base area by B and the height by H.

Mathematically,

V = B * H.

Make B the subject of formula

B = V/H

Substitute 294 for V.

The expression becomes

B = 294/H

Now, let's assume the height is 6 inches.

The expression for base area becomes

B = 294/6

B = 49 in²

Answer:

Median and IQR

Step-by-step explanation:

If we are to accurately compare two data sets, the best measure of central tendency is median and best measure of variability is the MAD.

The reason is that:

1. Median is not affected by outlier or extreme value. Due to this, if we use the mean, it can be misleading if there is any case of outlier(s) in the data sets.

2. The interquartile range (IQR) is the middle half of the data. It uses the concept of median to operate - think about the median value that splits the dataset in half. Similarly, you can divide the data into quarters. This also is not affected by outlier(s) or extreme value(s).

NB: When we say middle half or middle number, we assumed you have sorted the data sets either in ascending order or descending order. This will put the data sets in order of their sizes. E.g., 1 < 2 < 3, etc.

Step-by-step explanation:

The only way I know how to do this is to create one fraction which is a combination of 2 steps used when 1 of the interior angles is known.

Formula

360/(180 - 9000/s ) = s

Multiply denominator and numerator on the left by s.

360 * s

=======                  = s        

s* (180 - 9000/s)

Remove the brackets on the denominator

360s

================    =s

180s - 9000

Cancel the numerators s's.

360 / (180s - 9000) = 1

Multiply both sides by 180s - 9000

360 =180s - 9000

Add 9000 to both sides

360 + 9000 = 180s

9360 = 180s

Divide by 180

9360/180 = 180/180 s

s = 52

Answer:

270 units³

Step-by-step explanation:

l×w×h = 10

lwh = 10

New Volume = (3l)×(3w)×(3h)

= 27×lwh

= 27×10

= 270 units³

Alternately,

Since the sides are increased in the same ratio,

The two prisms are similar figures

For similar figures,

volume1/volume2 = (side1/side2)³

New Volume/10 = (3/1)³ = 27

New Volume = 270 units³

Final answer:

The new volume of a rectangular prism, whose dimensions are tripled, is calculated by cubing the factor of increase (3) and multiplying it by the original volume. The new volume will be 270 cubic units.

Explanation:

If the original volume of a rectangular prism is 10 cubic units and the length, width, and height are all made three times as long, the new volume can be calculated using the principle that volume is proportional to the cube of the linear dimensions of the prism. This is often represented as V  imes L³ where V is volume and L is the linear dimension.

To find the new volume, you would multiply each dimension by 3 so the new length (L'), width (W'), and height (H') would be three times the original dimensions. The new volume would then be calculated as:

V' = L' times W' times H' = (3L) times (3W) times (3H)

Since the original volume (V = L  imes W  imes H) is given as 10 cubic units, and you've multiplied each dimension by 3, you would cube the factor of increase (3³ = 27) and multiply it by the original volume:

V' = 27  imes V = 27  imes 10 = 270 cubic units

Therefore, the new volume of the rectangular prism would be 270 cubic units.

Step-by-step explanation:

Answer:

(a) P (U and V) = 0.

(b) P (U|V) = 0.

(c) P (U or V) = 0.83.

Step-by-step explanation:

Mutually exclusive events are those events that cannot occur at the same time. That is, if events A and B are mutually exclusive then,

                                         [tex]P (A\cap B) = 0[/tex]

Given:

Events U and V are mutually exclusive.

P (U) = 0.27 and P (V) = 0.56

(a)

As events U and V are mutually exclusive, the probability of their intersection will be 0.

That is,

[tex]P(U\ and\ V) = P (U\cap V) = 0[/tex]

Thus, the value of P (U and V) is 0.

(b)

The conditional probability of event B given A is:

[tex]P(B|A) =\frac{P(A\cap B)}{P(B)}[/tex]

Compute the value of P (U|V) as follows:

[tex]P(U|V) =\frac{P(U\cap V)}{P(V)}\\=\frac{0}{0.56}\\ =0[/tex]

Thus, the value of P (U|V) is 0.

(c)

The probability of the union of two events, say A and B, is

[tex]P(A\ or\ B)=P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

Compute the value of P (U or V) as follows:

[tex]P(U\ or\ V)=P(U\cup V)\\=P(U)+P(V)-P(U\cap V)\\=0.27+0.56-0\\=0.83[/tex]

Thus, the value of P (U or V) is 0.83.

The events U and V are mutually exclusive. So, the value of P(U and V) is 0, the value of P(U|V) is 0, and the value of P(U or V) is 0.83 and this can be determined by using the given data.

Given :

A) P(U and V)

P(U and V) = P(U [tex]\cap[/tex] V) = 0

Because U and V are mutually exclusive events.

B) P(U|V)

[tex]\rm P(U|V) = \dfrac{P(U\cap V)}{P(V)}[/tex]

[tex]\rm P(U|V) = \dfrac{0}{0.56}[/tex]

P(U|V) = 0

C) P(U or V)

[tex]\rm P(U \;or\;V) = P(U\cup V)[/tex]

[tex]\rm P(U \;or\;V) = P(U)+P(V)-P(U\cap V)[/tex]

P(U or V) = 0.27 + 0.56 - 0

P(U or V) = 0.83

The events U and V are mutually exclusive. So, the value of P(U and V) is 0, the value of P(U|V) is 0, and the value of P(U or V) is 0.83 and this can be determined by using the given data.

Answer:

a = 9√10

b=3√10

Step-by-step explanation:

see attached for reference for any right triangle

in our case

c is the hypotenuse

hence

c² = a² + b²

we are given that c = 30

also that a is 3 times as long as b or,

a = 3b    

substituting these into the pytharogrean formula.

c² = a² + b²

30² = (3b)² + b²

900 = 9b²+b²

10b² = 900

b² = 90

b = √90 = √9 √10 = 3√10

earlier we found that a = 3b,

hence

a = 3(3√10)

a = 9√10

so

The area of a regular hexagon is the same that the area of six congruent equilateral triangles

The area of one equilateral triangle in the regular hexagon is equal to

[tex]A=\frac{1}{2}(b)(h)[/tex]

where

b is the base of triangle (the length of the regular hexagon)

h is the height of triangle (the apothem of the regular hexagon)

solve for W

[tex]22.5=2W+6\\2W=22.5-6\\2W=16.5\\W=8.25\ in[/tex]

Find the value of L

[tex]L=W+6[/tex]

substitute the value of W

Final answer:

To convert a fraction to a percent, divide the numerator by the denominator to get a decimal, multiply the decimal by 100, and then add the percent symbol (%).

Explanation:

To convert a fraction to a percent, you start by converting the fraction into a decimal. To do this, divide the numerator (the top number) by the denominator (the bottom number). Once you have the decimal, you multiply it by 100 to get the percent value. Finally, append the percent symbol (%) to the number.

Example:

For the fraction 3/4, first convert it to decimal:

Another way to convert fractions to percent is by finding an equivalent fraction that has 100 as its denominator. Then, simply use the numerator as the percent. If the fraction's denominator is not easily scalable to 100, it is easier to use the decimal method described previously.
