The required value of p(e and f) is 0.24, which is calculated using the conditional probability formula.

What is conditional probability?

Conditional probability is the measure in probability theory that depicts the probability of occurrence of an event given that another event has already occurred. Its mathematical formulation is given by:

P(A/B) = P(A∩B) / P(B)

Here, A is the event and B has already occurred

The calculation for the value of p(e and f)

The assigned value of p(e) = 0.6

Conditional probability, p(f/e) is given as 0.4

We know, that conditional probability = p(e∩f) / p(e)

W need to calculate p(e∩f) which is equal to p(f/e) × p(e)

p(e∩f) = 0.4 × 0.6

= 0.24

Hence, the value of p(e and f) is 0.24.

The number of games that will be played will be 8 games.

It should be noted that the mathematical relationship between the total cost for a person to bowl at the local bowling alley and the number of games played is represented by

y = 3.50x + 6.00.

The games that you can bowl for $34 will be:

y = 3.50x + 6.00.

34 = 3.50x + 6.00.

Collect like terms

3.50x = 34 - 6

3.50x = 28

Divide

x = 28 / 3.50

x = 8

Therefore, the number of games will be 8 games.

d= 17/2 is the solution of the given equation 43-3 d=d+9.

According to the given question.

We have a linear equation in one variable 43 -3d = d + 9.

Since, we have to solve the above linear equation in one varible 43 -3d = d + 9, which means we have to solve the above equation for d.

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofore, the solution of the given linear equation in one variable 43 -3d = d + 9 is given by

43 -3d = d + 9

⇒ 43 - 9 -3d = d          (subtracting 9 from both the sides)

⇒ 34 = d + 3d      (adding 3d both the sides)

⇒ 34 = 4d

⇒ d = 34/4

⇒ d = 17/2

Now, we will check whether d = 17/2 is the solution of the given equation or not.

Thereofore,

LHS

= 43 - 3(17/2)

= 43 - 51/2

= 86 - 51/2

= 35/2

RHS

= 17/2 + 9

= 17 + 18/2

=35/2

Here, LHS = RHS for d = 17/2

Hence, d= 17/2 is the solution of the given equation 43-3 d=d+9.

The inequality given by 3n < -4(2 + n) has the solution n < -8/7 or (-∞ , -8/7).

Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.

To solve an inequality is to find the values of x such that when we substitute that number for x we have a true statement.

Given the inequality 3n < -4(2 + n), expand the right term by distributing -4 inside the parenthesis.

3n < -4(2 + n)

3n < -8 - 4n

Add 4n to both sides.

3n + 4n < -8 - 4n + 4n

7n < -8

Divide both sides by 7

7n < -8

n < -8/7

To check, let n = -9/7

n = -9/7 < -8/7

Substitute this value to the inequality.

3n < -4(2 + n)

The equation of the line passing through points (-2,5) and (3,-4) is 9x + 5y = 7.

Hence, option C) 9x + 5y = 7 is the correct answer.

Given the data in the question;

Point1 (-2,5)

Point2 (3,-4)

First, we determine the slope of the of the line,

m = (y₂-y₁)/(x₂-x₁)

m = ( -4-5 )/( 3-(-2) )

m = -9/5

Using the formula for equation, we determine the y-intercept

y = mx + b

Plug in the first point (-2,5) and the slope and then solve for the y-intercept b.

5 = -9/5(-2) + b

5 = 18/5 + b

b = 5 - 18/5

b = ( 25 - 18 )/5

b = 7/5

Now, plug the slope and y-intercept into y = mx + b to determine the equation of the line.

y = mx + b

y = -(9/5)x + 7/5

Convert to standard form

y = -(9/5)x + 7/5

Multiply each term by 5

5y = -9x + 7

5y + 9x = 7

9x + 5y = 7

The equation of the line passing through points (-2,5) and (3,-4) is 9x + 5y = 7.

If a central angle and an inscribed angle intersect the same arc, the central angle is twice the inscribed angle and half the central angle.

According to the inscribed angle theorem, an angle inscribed in a circle is half the central angle 2 that subtends the same arc on the circle.

The central angle has the same length as the intercepted arc. As can be seen, if a central angle and an inscribed angle intersect the same arc, the central angle is twice as large as the inscribed angles. Similarly, the inscribed angle equals half of the central angle.

An inscribed angle is one that has its vertex on a circle and its sides are chords. The intercepted arc is the arc that is contained within the inscribed angle and has its endpoints on the angle.

If a central angle and an inscribed angle intersect the same arc, the central angle is twice the inscribed angle and half the central angle.

Answer:

No, because 2(21) + 13 is not equal to 43.

The Dolphins scored 10 points.

Step-by-step explanation:

A = 13 + 2D

43 = 13 + A + D

43 = 13 + 3D

43 - 13 = 30

30 = 3D

30/3 = 10

D = 10

A = 13 + 2(10)

A = 33

D + A = 43

33 + 10 = 43

Therefore, the Atlanta Falcons scored 33 points which is 13 points more than twice what the Dolphins scored.
