Given:

Equation of a line is

[tex]x-3y=-18[/tex]

To find:

The slope of the line perpendicular to the given line.

Solution:

The slope of the equation [tex]ax+by=c[/tex] is

[tex]Slope=-\dfrac{a}{b}[/tex]

We have,

[tex]x-3y=-18[/tex]

Here, a=1, b=-3. So, slope of this line is

[tex]m_1=-\dfrac{1}{-3}[/tex]

[tex]m_1=\dfrac{1}{3}[/tex]

Product of slopes of two perpendicular lines is -1.

Let slope of perpendicular line is [tex]m_2[/tex].

[tex]m_1\cdot m_2=-1[/tex]

[tex]\dfrac{1}{3}\cdot m_2=-1[/tex]

[tex]m_2=-3[/tex]

Therefore, the slope of the perpendicular line is -3.

Answer:

D. 81 sq. ft.

Step-by-step explanation:

We know x, y, and z's lengths. Those are 3, 12, and 9 respectively.

I first imagined a 12 by 9 rectangle and then figured about the area of the shaded part.

The 12 by 9 rectangle is 108 sq ft, But there is a empty part on the top left. That would be a 9 ft by 6 ft triangle.

The area of a triangle can be figured out with this formula: A = bh/2 Substitute b and h for 9 and 6 respectively.

A = (9 * 6)/2

A = 54/2

A = 27 sq. ft.

Now, subtract 27 from 108 to get the area of the shaded part.

108 - 27

81 sq. ft.

The area of the tile being used is 81 sq. ft.

Given:

The expression is

[tex]10+(2\times 3)^2:4\times \dfrac{1}{2}[/tex]

To find:

The value of the expression.

Solution:

We have,

[tex]10+(2\times 3)^2:4\times \dfrac{1}{2}[/tex]

It can be written as

[tex]=\dfrac{10+(2\times 3)^2}{4\times \dfrac{1}{2}}[/tex]

[tex]=\dfrac{10+(6)^2}{2}[/tex]

[tex]=\dfrac{10+36}{2}[/tex]

[tex]=\dfrac{46}{2}[/tex]

[tex]=23[/tex]

Therefore, the value of the given expression is 23.

Answer:

i. A = 4 + 3t .......... 1

  B = 12 + 2t .......... 2

ii. The hours required would be 8 hours.

Step-by-step explanation:

The charges at each of the garages can be expressed as;

i. For garage A,

A = 4 + 3t .......... 1

ii. For garage B,

B = 12 + 2t .......... 2

where A is the amount charged at garage A, B is the amount charged at garage B, and t is the number of hours.

To determine the number of hours  parked that would make the cost of each garage the same.

Let:

equation 1 = equation 2

4 + 3t = 12 + 2t

collect like terms

3t - 2t = 12 - 4

t = 8

The hours that would make the cost of each garage the same is 8 hours.

Answer:

<A = 44

Step-by-step explanation:

A triangle is 180 degrees

(x+59) + (x+51) + 84 = 180        >> add everything on the left side

2x + 194 = 180                          >> subtract both sides by 194

2x = -14                                     >> divide both sides by 2 to get x alone

x = -7

since you are finding A<, substitute

<A = x + 51

<A = (-7) + 51

<A = 44

Answer:it is the third option

Step-by-step explanation:

I took the test (:

Least likely event means probability of its occurrence is minimum among other events. The least likely events from the given events is: Option B: A randomly selected student who is a freshmen owns a skateboard

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For two events A and B, by chain rule, we have:

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

Suppose that there are two events A and B. Then suppose the conditional probability are:

We can then use the chain rule to find them, or Baye's theorem also helps in finding these probabilities.

We are given the following table of joint relative frequency:

[tex]\begin{array}{cccc}&\text{Freshmen(B)}&\text{Non-Freshmen(B')}&\text{Total}\\\text{Owns a skateboard(A)}&40&110&150\\\text{Doesn't own skateboard(A')}&210&840&1050\\\text{Total}&250&950&1200\end{array}[/tex]

We named events as A, A' and B and B' (event and their complements).

The important probabilities which are going to be used are evaluated as:
[tex]P(A) = \dfrac{n(A)}{n(S)} = \dfrac{150}{1200} = \dfrac{1}{8}[/tex]

[tex]P(B) = \dfrac{n(B)}{n(S)} = \dfrac{250}{1200} = \dfrac{5}{24}[/tex]

[tex]P(A') = 1 - P(A) = \dfrac{7}{8}\\\\P(B') = 1-P(B) = \dfrac{5}{24} = \dfrac{19}{24}[/tex]

[tex]P(A \cap B) = \dfrac{n(A \cap B)}{n(S)} = \dfrac{40}{1200} = \dfrac{1}{30}\\\\P(A' \cap B') = \dfrac{n(A' \cap B')}{n(S)} = \dfrac{840}{1200} = \dfrac{7}{10}\\P(A' \cap B) = \dfrac{n(A' \cap B)}{n(S)} = \dfrac{210}{1200} = \dfrac{7}{40}[/tex]

Evaluating probabilities of choices given, we get:

Case 1: E = A randomly selected student who owns a skateboard is a freshmen

P(E) = ?

P(E) = P(B|A) = [tex]\dfrac{P(A \cap B)}{P(A)} = \dfrac{1/30}{1/8} = \dfrac{4}{15}[/tex]

Case 2: E = A randomly selected student who is a freshmen owns a skateboard:

P(E) = P(A|B) = [tex]\dfrac{P(A \cap B)}{P(B)} = \dfrac{1/30}{5/24} = \dfrac{4}{25}[/tex]

Case 3: E = A randomly selected student who doesn't owns a skateboard is a freshmen

P(E) = P(B|A') = [tex]\dfrac{P(A' \cap B)}{P(A')} = \dfrac{7/40}{19/24} = \dfrac{21}{95}[/tex]

Case 4: E = A randomly selected student who doesn't owns a skateboard is not a freshmen

P(E) = P(B'|A') = [tex]\dfrac{P(A' \cap B')}{P(A')} = \dfrac{7/10}{19/24} = \dfrac{84}{95}[/tex]

Thus, the least probability is for the second case.

Thus, the least likely event(the event having least probability) from the given events is: Option B: A randomly selected student who is a freshmen owns a skateboard

Answer:

60°

Step-by-step explanation:

Since, all sides of the given triangle are marked with identical signs.

So, measures of all sides are equal.

Therefore, it is an equilateral triangle.

Measure of each angle of an equilateral triangle is 60°.

So, x = 60° ( Alternate angles)

Answer:

The point-slope form of an equation of the line is:

[tex]y-9 = 5(x+2)[/tex]

Step-by-step explanation:

Given

Slope m = 5

Point (-2, 9)

Point slope form of an equation of a line:

Point slope form of an equation of a line is defined as

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

In our case,

substituting the values m = 5 and the point (x₁, y₁) = (-2, 9) in the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 9 = 5 (x - (-2)[/tex]

[tex]y-9 = 5(x+2)[/tex]

Therefore, the point-slope form of an equation of the line is:

[tex]y-9 = 5(x+2)[/tex]

Answer:

Option (3)

Step-by-step explanation:

If the sides of a triangle are unequal then the measure of sides opposite to these angle will be in the order from least to greatest.

In ΔABC,

m∠CAB = 180°- (m∠B + m∠C)

        = 180° - (25° + 27°)

        = 180° - 52°

        = 128°

Since, ∠CAB > ∠ABC  ∠ACB

Therefore, a > b > c ---------(1)

Now from ΔADB,

m∠BAD + m∠ADB + m∠DBA = 180°

32° + m∠ADB + m∠35° = 180°

m∠ADB = 180° - 67°

             = 113°

Since, m∠ADB > m∠DBA > m∠BAD

Therefore, c > d > e -------(2)

Combining both the inequalities,

a > b > c > d > e  

Option (3) will be the answer.
