A boss plans a business meeting at Starbucks with the two engineers below him. However, he fails to set a time, and all three arrive at Starbucks at a random time between and p.m. When the boss shows up, if both engineers are not already there, he storms out and cancels the meeting. Each engineer is willing to stay at Starbucks alone for an hour, but if the other engineer has not arrived by that time, he will leave. What is the probability that the meeting takes place

Answers

Answer 1

The probability that the meeting takes place is 7/24.

What is the probability?

Probability is defined as the ratio of the number of favorable outcomes of an event to the total number of possible outcomes(sample space) of the event.

It is given by

P(A) = n(A)/n(S)

Where A - event, S - sample space

Calculation:

From the given data,

The probability, if the engineers arrive in the first hour and the boss arrives in the second hour is 1/8,

So, the meeting will be held i.e., p = 1.

The probability, if all the three arrive in the same hour (first or second)

= 1/8 + 1/8

= 1/4

So, the meeting will be held only if the boss (he may arrive first, second, or last) arrives last, the probability is 1/3

The probability, if one of the engineers arrives in the first hour while the other engineer and the boss arrive in the second hour is

= 1/4

So, the meeting will be held only if the second engineer arrives before the boss and before the first engineer leaves, the probability is 1/3

Thus, the final probability for the meeting to take place is

= (1/8) × 1 + (1/4) × (1/3) + (1/4) × (1/3)

= 7/24

Therefore, the required probability is 7/24.

How do you solve -8 -x = x -4x

Answers

Answer:

hey there

x = 4

Step-by-step explanation:

Let's solve your equation step-by-step.

−8−x=x−4x

Step 1: Simplify both sides of the equation.

−8−x=x−4x

−8+−x=x+−4x

−x−8=(x+−4x)(Combine Like Terms)

−x−8=−3x

−x−8=−3x

Step 2: Add 3x to both sides.

−x−8+3x=−3x+3x

2x−8=0

Step 3: Add 8 to both sides.

2x−8+8=0+8

2x=8

Step 4: Divide both sides by 2.

2x/2  = 8/2

x= 4

Order the angles in each triangle from smallest to largest.

Answers

the answer is D

an easy way to think about it is considering the missing side from the measures given
for example LN = 17, the missing side is M so we know that the measure of angle M is 17, which is the smallest
for MN = 21, the missing side is L so the second smallest is angle L

Find the surface area of the
triangular prism.
10 ft.
3 ft.
3 ft

Answers

Given:

The figure of a triangular prism.

To find:

The surface area of the triangular prism.

Solution:

We know that, a triangular prism contains 2 congruent triangular surface and 3 rectangular surface.

Triangles have base 3 ft and height 2 ft.

Area of a triangle is

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

[tex]A_1=\dfrac{1}{2}\times (3)\times (2)[/tex]

[tex]A_1=3[/tex]

Area of congruent triangles are congruent. So,

[tex]A_1=A_2=3\text{ sq. units}[/tex]

Now the three rectangular surface have dimensions 10 by 3, 10 by 3 and 10 by 3 because the triangles are equilateral and the length of the prism is 10 ft.

Area of a rectangle is

[tex]Area=Length\times width[/tex]

[tex]A_3=10\times 3[/tex]

[tex]A_3=30[/tex]

Dimensions of all three rectangles are same, therefore there areas are equal.

[tex]A_3=A_4=A_5=30[/tex]

Now, the total surface area of the prism is

[tex]A=A_1+A_2+A_3+A_4+A_5[/tex]

[tex]A=3+3+30+30+30[/tex]

[tex]A=96[/tex]

Therefore, the total surface area of the prism is 96 sq. ft.

how to the medium in the dot line????!! I don't want my mom to be mad at my grade please!!!!!!

Thank you whoever helps me!

Answers

Answer: To find the median, count the dots from left to right until you find the middle value.

Step-by-step explanation:

Ok so first it's not a dot line it's a dot plot. Second, let's define what a medium is. The medium is the "middle" of a sorted list of numbers. To find the Median, place the numbers in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. The middle number is 15, so the median is 15. Tip to find the median from a list of value ordered numbers every time cross a number from each side. For example, if you cross 13 from above also cross 26 and if you cross 23 then also cross 10.

Back to your original question of how to find the medium on a dot plot you need to take all the numbers from your dotted line put them in order even if they are repeated and then cross each one on each side from right to left. Also remember if you cross out all the numbers right and left and end up with two numbers left then take them and add them and then divide by 2 and that will be the median.

Tell weather each pair is parallel, perpendicular, or neither: y= 3x + 2 2y= 6x -6

Answers

The pair are parallel to eachother. The second equation in slope intercept form is y = 3x-3, since they have the same slope they’re parallel.
They are parallel!
When you put 2y=6x-6 into slope intercept form, you get y=3x-3.
They are parallel because they have the same slope.
Perpendicular lines have opposite reciprocal slope. For example, one equation would have a slope of 3 and the second one would have a slope of -1/3.
Hope that makes things more understandable!

A medical provider is doing a study to determine the average time spent waiting before an appointment. The current average wait time is 34 minutes, which is 15% shorter than the average was when the study started. What was the average wait time then?

Answers

Answer:

39.1 minutes

Step-by-step explanation:

Given that:

Current wait time = 34 minutes

Current wait time is 15% shorter than average wait time when study started.

Average wait time when study started :

15% of current wait time :

0.15 * 34

= 5.1 minutes

Average wait time when study started :

34 minutes + 5.1 minutes

= 39.1 minutes
