b = - [tex]\frac{1}{2}[/tex]

multiply both sides by 2(b + 1) to eliminate the fraction

3 = 3× 2(b + 1)

3 = 6(b + 1) = 6b + 6  ( subtract 6 from both sides )

- 3 = 6b ( divide both sides by 6 )

b = - [tex]\frac{3}{6}[/tex] = - [tex]\frac{1}{2}[/tex]

Answer:Partial quotients Paloma should show in her work are B) 30,10,1.

Step-by-step explanation:

Given : Paloma dividing 1292 (dividend) by 31 (divisor) using partial quotients.

so the easy multiples of 31 are as 31×2=62 ,31×3=93,31×10=310....so on

if she uses 30 as her first partial quotient then 31×30=930, so after subtracting 930 from 1292 we get 362 as new dividend then 31×10=310 is the easiest multiple of 31 so that 362-310=52 as new dividend ,then 31×1=31 subtracting this from 52 gives 52-31=21 which is the remainder.

Therefore, Partial quotients Paloma should show in her work are 30,10 and 1.

The equation is y=mx+b

so it would be y=2/7(x)-12

Simplifying

18x + -44 = 13y + -38

Reorder the terms:

-44 + 18x = 13y + -38

Reorder the terms:

-44 + 18x = -38 + 13y

Solving

-44 + 18x = -38 + 13y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '44' to each side of the equation.

-44 + 44 + 18x = -38 + 44 + 13y

Combine like terms: -44 + 44 = 0

0 + 18x = -38 + 44 + 13y

18x = -38 + 44 + 13y

Combine like terms: -38 + 44 = 6

18x = 6 + 13y

Divide each side by '18'.

x = 0.3333333333 + 0.7222222222y

Simplifying

x = 0.3333333333 + 0.7222222222y

Final answer:

The conditional probability formula for event B given event A is represented as P(B|A), which is calculated using P(A and B) / P(A). Using dice as an example, the events are described and demonstrated to be neither mutually exclusive nor independent due to overlapping outcomes and interdependence.

Explanation:

The conditional probability of event B given that event A has occurred is represented as P(B|A). To fill in the blanks in the provided formula, it would be P(B | A) = P(B ∩ A) / P(A). Using the provided scenarios, we need to calculate P(A), which is the probability that the sum of numbers on both cubes is less than 10, P(B), which is the probability that the sum of numbers on both cubes is a multiple of 3, and P(A and B), which is the probability that both events occur simultaneously. Finally, we use the formula P(A|B) = P(A and B) / P(B) to calculate the conditional probability.

For example, event A could be rolling a 3 or 4 first, followed by any even number, and event B could be rolling a sum at most 7 on two dice. These events are not mutually exclusive since they can both occur simultaneously, nor are they independent since the occurrence of one affects the likelihood of the other happening.

The completed conditional-probability formula is: P(B|A) = P(A ∩ B) / P(A)

To complete the conditional-probability formula for event B given that event A occurs first, we need to fill in the blanks with the appropriate terms:

P(B|A) = P(A ∩ B) / P(A)

Let's break down each term:

a0: Event A occurs

a1: Event B occurs

a2: Event A and B occur simultaneously (intersection of A and B)

a3: Event A occurs

a4: Event B occurs

Therefore, the completed conditional-probability formula is:

P(B|A) = P(A ∩ B) / P(A)

Answer:

a) circumference of great circle=40212.4km

b) circumference of latutude circle=40212.4cos[tex]\theta[/tex] kilometers

c)The latitude circle is at an angle of 84.9°

d)Circumference of equator=40212.4km

Step-by-step explanation:

Refer to the figure shown below, we are given that earth has been charted with vertical and horizontal line and horizontal lines are called latitude lines.

So every horizontal line corresponds to a circle.

So the great circle will have radius equal to earth radius.

a)we are given with earth radius=6400km.

Hence circumference of a great circle= 2πX6400=40212.4km

b)At a latitude with angle x=[tex]\theta[/tex], the circumference of latitude circle = [tex]40212.4cos\theta[/tex]

c)If a latitude circle has a circumference of about 3593km,

then [tex]40212.4cos\theta=3593[/tex]

        [tex]cos\theta=\frac{3593}{40212.4} =0.0894[/tex]

         [tex]\theta=cos^{-1}(0.0894)[/tex]=84.9°

Hence the latitude circle is at an angle of 84.9°

d) At equator angle is 0.

Hence circumference of equator=40212.4cos(0)=40212.4km

If your question is, "how much had Mr. Kork paid for the car?"

(8,400-200)/.4=$20,500

Achristensen's answer is correct. Just want to add a little more explanation how to arrive at the result.

let x be the original price.

Rewrite the verbal question as an equation using x:

8400 = 200 + 2/5 * x

solve for x:

8400-200 = 2/5*x

5/2*8200 = x

x = 20500

The original price was $20,500

Answer:

it is 1905.88%

Step-by-step explanation:

We have,85%x X=1620

Or 85/100*x=1620

multiplying both sides by 100 and dividing both sides by 85

we have x = 1620 * 100/85

x=1905.88

if you are using a calculator ,simply enter 1620x100÷85,which will give you the answer

85 dinner rolls represent approximately 5.25% of 1620 dinner rolls. The calculation is done by dividing 85 by 1620 and then multiplying by 100.

To find what percent of 1620 dinner rolls is 85 dinner rolls, we use the basic formula of (part/whole) x 100. In this case, the 'part' is the 85 rolls, and the 'whole' is the 1620 rolls. So we calculate the percentage as follows:

(85 / 1620) x 100 = (0.05247) x 100 [10pt] [10pt]= 5.247%

Thus, 85 dinner rolls are approximately 5.25% of 1620 dinner rolls.

Rob spent 25% extra percent on his project than the had planned.

Let us assume total number of hours spent x hours.

Given that he spent an extra h hours on the project

So, we could say 25% of x is h.

0.25 x = h.

Dividing both sides by 0.25.

We get 0.25h/0.25 = h/0.25.

x = h/0.25.

Let us convert 0.25 into fractions.

0.25 = 25/100 = 1/4.

Therefore,

x = h/1/4 = 4h.

Therefore, Rob planned 4h hours.

He spent h hours extra.

So, he spent total 4h+h = 5h hours total.

Let x the number of brochures and y the number of fliers.

Optimizing function⇒ f(x,y) = 0.1 x + 0.06 y

Constraints:

x ≥ 80

y ≥ 100

3x + 2y ≤ 500

See the attached figure which represents the constraints.

From the attached figure:

The vertices of the feasible region are (80, 100), (80, 130) and (100, 100).

Substitute the points (80, 100), (80, 130) and (100, 100). in the function

f(x,y) = 0.1 x + 0.06 y

If (x,y) = (80, 100) ⇒ f(x,y) = 14

If (x,y) = (80, 130) ⇒ f(x,y) = 15.8

If (x,y) = (100, 100) ⇒ f(x,y) = 16

The minimum value 14 at (80, 100).

To minimize the cost, she would print 80 brochures and 100 fliers.

This is an optimization problem in mathematics that can be solved by linear programming. The constraints of the problem can be represented by inequalities, and the objective function (cost of printing) can be minimized by finding the optimal number of brochures and fliers to print.

This question is a type of optimization problem in mathematics, specifically a type of problem often found in linear programming. The objective is to minimize the cost of printing brochures and fliers.

First, set up the inequalities based on the constraints. Let x be the number of brochures and y be the number of fliers.

Then, we need to find the number of brochures and fliers to minimize the cost, which is 0.10x + 0.06y. You can solve this problem using methods of linear programming, such as graphing the feasible region and finding the minimum point.

Answer:

[tex]Distance = 9\\[/tex]

See attached image

The distance between -13 and -4 on a number line is the absolute value of their difference, which is 9 units.

The distance between two points on a number line is the absolute difference between those points. In this case, the points are -13 and -4. To calculate the distance, we subtract these values in such a way that we get a positive result.

So, we subtract -4 from -13, which is the same as adding 4 to 13, i.e.,: -13 - (-4) = -13 + 4 = -9.

However, distance cannot be negative, so we take the absolute value of -9, which is 9. Therefore, the distance between -13 and -4 on the number line is 9 units. None of the options provided seem to correctly represent this result.

3. The estimated seating capacity difference between the Atlanta and Los Angeles arenas is 1,300.

4. The total attendance for the sold-out games is 37,124 people.

5. The combined capacity of the Cleveland and Boston arenas is 6,186 people greater than the biggest college basketball arena.

1. **Last night's game in Cleveland:**

  The attendance at the Cleveland arena last night was 20,562 - 251 = 20,311 people. This is because the arena was 251 seats short of being filled to its full capacity.

2. **Difference in seating capacities:**

  The difference in seating capacities between the largest (Los Angeles) and smallest (New Orleans) arenas is calculated by subtracting the smaller capacity from the larger one: 20,300 - 18,500 = 1,800. Therefore, the largest arena can accommodate 1,800 more people than the smallest arena.

3. **Estimate of seating capacity difference (Atlanta and Los Angeles):**

  The estimated difference in seating capacities between the Atlanta and Los Angeles arenas can be obtained by rounding the capacities to the nearest hundred, making the calculation easier. The rounded capacities are 20,300 and 19,000, resulting in an estimated difference of 1,300.

4. **Attendance at sold-out games:**

  The total attendance for the sold-out games in Boston and New Orleans is the sum of their individual capacities: 18,624 + 18,500 = 37,124 people.

5. **Combined capacity of Cleveland and Boston vs. biggest college arena:**

  The combined capacity of the Cleveland and Boston arenas is 20,562 + 18,624 = 39,186 people. Since this is greater than the capacity of the biggest college basketball arena (33,000), the combined capacity of the Cleveland and Boston arenas is 6,186 people greater.

In summary, the attendance at the Cleveland arena last night was 20,311 people. The largest arena can seat 1,800 more people than the smallest arena. The estimated seating capacity difference between the Atlanta and Los Angeles arenas is 1,300. The total attendance for the sold-out games in Boston and New Orleans is 37,124 people.
