Using conditional probability, it is found that there is a 0.83 = 83% almost 0.8403  probability that this student does spend more than $25 a week on gas, given that he/she does commute to school each day.

Probability: -

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%).

Conditional Probability :

Using conditional probability, it is found that there is a 0.83 = 83% = P( A∩ B) / P(A)

In which

In this problem:

Event A: Commute to school each day.

Event B: Spends more than $25 a week.

80% indicated that they commute to school each day. of those that commute to school each day, hence , P(A) = 0.8

Of those, 83% spend more than $25 a week on gasoline, hence .

Congruency is a term used to describe two objects with the same shape and size.

In this case, two triangles are congruent if they have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position.

For instance,

these triangles are congruent. They have the same sides but in different position.

Another example is

In this case the congruency is about angles. These 2 triangles have the same angles and the same sides but in different positions.

Another instance is

They are the same triangles but in different positions.

From the first question we can see that both triangles are congruent.

This imply that they are the same but in different position:

We can note that angle C is equal to angle T, therefore

In the same way, angle U is equal to angle B, then we have

We can find angle A by noticing that the interior angles of a triangle add up 180, that is

Since angle V is equal to angle A, also V=66

Answer: I believe it is A.

Step-by-step explanation:let me start by saying that D and B aren't true because u is greater than 3 to the square root of 3, which is roughly 5.2. So were left with A and C. Then we realize that 3 to the square root of 3 is the same as 3 to the square root of 3, so it can't be C, so were left with A.

What do you know?

the troposphere extends 8 to 20 km above the Earth's surface. The surface temperature is 15°C and decreases at a rate of 6.5°C per kilometer away.

What do you want to find out?

The temperature at any point of the troposphere

What kind of answer do you expect?

Any value below 15°C

2. Define variables,

T is for temperature, and

d is the distance away from the surface

3. What is the b -value

b = 15

which is the Earth's surface temperature or the initial temperature for our problem

4. What is the slope

the slope 'm' equals -6.5

which means that the temperature decreases 6.5°C per km

5. write the equation

the general form for this equations is y = b + mx

thus, for our problem, the equation is: T = 15 - 6.5*d

6.

a) the slope represents the rate of change of temperature with respect to distance, since m = -6.5 °C/km , this means the troposphere is getting 6.5 °C colder per km away from Earth's surface

b) the y-intercept represents the Earth's surface temperature

Graph:

7. identify 3 points

when d = 0 then T = 15, so our first point is (0,15)

when d = 1 then T = 15 - 6.5 = 8.5 , so our second point is (1,8.5)

when d = 2 then T = 15 - 13 = 2 so our third point is (2,2)

8. calculate the slope

let's use this equation and this set of points,

let's replace and solve

We can see that it does match the slope from our model, which is -6.5

True about translations is they can help you see if two figures are congruent

What are translations?

In mathematics, a translation is an up, down, left, or right movement of a shape. Because the translated shapes appear to be exactly the same size as the original ones, they are consistent with one another. Just one or more directions have been altered. There is no change in the shape because it is simply being moved from one location to another.

Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.

Hence, they can help you see if two figures are congruent.

Two or more expressions with an Equal sign is called as Equation.

Given,

The number set has numbers

Five comma, six comma, seven comma eight

Now x=6

6(2x+12)=6(2(6)+12)

=6(12+12)

The number of Screamers when Runners are 6 is 4,

and the number of Runners when Screamers are 10 is 15.

It is basically the measurement of two numbers and it compares by how much one quantity is bigger than another.

When two ratios are equal, they are usually said to be in proportion.

As given in the above questions,

Screamers:Runners= 2:3

So, let the number of screamers in first case is x

Then, x:6 = 2:3

         x= 4

Hence , the number of screamers is 4.

In second case, let the number of runners is y

Then, 10:y = 2:3

Answer:

Rides cost $4

Games cost $2.50

Step-by-step explanation:

Let g = cost of games

Let r = cost of rides

6g + 3r = 27

2g + 9r = 41  Multiple this through by -3 and then add to the equation above.

-3(2g + 9r) = (41) -3

-6g - 27r = - 123

6g + 3r = 27

       -24r = -96  Divide both sides by -24

r = 4  This is the cost of the rides.

Plug is 4 for r in either of the two original equations to solve for g

6g + 3r = 27

6g + 3(4) = 27

6g + 12 = 27  Subtract 12 from both sides

6g = 15  Divide both sides by 6

g = 2.5  This is the cost of the games.

The fraction of 2 hrs 15 minutes to 1/4 of an hour is 1/9.

What is fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Since,

1 hour = 60 minutes.

2 hours = 120 minutes.

2 hours 15 minutes = 120 + 15 = 135 minutes.

1/4 of an hour = 60/4 = 15 minutes.

So, the fraction is,

[tex]\frac{15}{135} = \frac{1}{9}[/tex]

Therefore, the fraction of 2 hrs 15 minutes to 1/4 of an hour is 1/9.

The measures of the numbered angles in the rhombus ABCD if m∠ABC = 49° are m∠1 = 24.5°, m∠2 = 90°, m∠3 = 24.5° and m∠4 = 65.5°.

We are given:

A rhombus ABCD and m∠ABC = 49°.

The diagonal of the rhombus divides the angles into 2 equal parts. Therefore,

m∠1 = m∠ABC / 2 = 49 / 2 = 24.5°

The diagonal AC is perpendicular to the diagonal DB.

And we know that diagonals bisect each at right angles.

So, m∠2 = 90°.

Opposite angles of the rhombus are equal.

Therefore,

∠B = ∠D

multiply both sides by 1/2, we will get;

1/2 ∠B = 1/2 ∠D

m∠1 = m∠3 = 24.5°

Sum of angles in a quadrilateral = 360°

360 -  98 = 262°

∠A = ∠C = 262 / 2 = 131

Therefore,

m∠4 = 1 / 2 ∠C

m∠4 = 1 /2 * 131

m∠4 = 65.5°

Thus, the measures of the numbered angles in the rhombus ABCD if m∠ABC = 49° are m∠1 = 24.5°, m∠2 = 90°, m∠3 = 24.5° and m∠4 = 65.5°.

To find this, we divide their ages in the order Grandpa : Grandson as following:

Simplify the fraction by a factor of 8

This is how many times George's grandpa is older than him.

We have the next equation

42=6a

we need to clear a

a=42/6

a=7

the answer is 7

in this problem we have that

y+20=x+15 -------> by vertical angles

isolate variable y

y=x+15-20

y=x-5 ------> equation A

and

(3x+5)+(x+15)=180 ------> by form a linear pair (sipplementary angles)

solve for x

4x+20=180

4x=160

x=40

substitute the value of x in equation A

y=40-5

y=35

therefore

x=40 and y=35

The equation is modelled as [tex]y\ = \frac{kx}{z^2}[/tex].

Given,

y varies directly with x

y varies inversely with square of z

According to given data the equation can be modelled as follows:

y varies directly with x, it can be written as [tex]y \ \alpha \ x[/tex]

and also y varies inversely with square of z, it can be written as [tex]y\ \alpha \ \frac{1}{z^2}[/tex]

Combining both, then we get,

[tex]y\ \alpha \ \frac{x}{z^2}\\\\y\ = \frac{kx}{z^2}[/tex]

Where, k is proportionality constant.

Thus, the combined equation is modelled as [tex]y\ = \frac{kx}{z^2}[/tex].
