I Need Help With This Question

Answers

Answer 1

Answer:

14x+4 = 4x+44

14x - 4x = 44 - 4

10x = 40 ...... x = 4

《60°》.....

5y = 120

y = 120/5 => y = 24

Answer 2
Angle B=14x+4
Angle D=4x+44
14x+4=4x+44
14x-4x=44-4
10x=40
x=4
Angle B=14•4+4=60
Angle D=4•4+44=60
Angle C=180-60
Angle C=120
5y=120
y=24
Angle C=24
Angle A=24

pdf Ron, Sue, and Ted arrive at the beginning of a professor’s office hours. The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours. (a) What is the expected time until only one student remains? (b) For each student, find the probability they are the last student left. (c) What is the expected time until all three students are gone?

Answers

Answer:

a) 0.45 hours

b)

P( Ron ) = 7/12

P( sue ) = 4/15

P(Ted ) = 3/20

c)  1.22 hours

Step-by-step explanation:

Ron , sue and Ted

mean values = 1, 1/2 , 1/3  hours

a) determine the expected time until only one student remains

E(x) = 9/20 = 0.45 hours

b) Probability that each student is the last student left

P( Ron ) = 7/12

P( sue ) = 4/15

P(Ted ) = 3/20

C) Time until all students are gone

= 146 / 120 =  1.22 hours

attached below is the detailed solution

This question is based on the concept of probability.Therefore, the answers are as follows:

(a) 0.45 hours

[tex]\bold{(b) \, P(Ron) = \dfrac{7}{12} ,P (Sue) = \dfrac{4}{15} ,P(Ted) = \dfrac{3}{20}\beta}[/tex]  

(c)  1.22 hours

Given:

The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours.

According to the question,

The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours.

(a) The expected time until only one student remains,

[tex]E(X) = \dfrac{9}{20} = 0.45 \,hours[/tex]

(b)  Now, find the probability they are the last student left,

[tex]P(Ron) = \dfrac{7}{12} \\P (Sue) = \dfrac{4}{15} \\P(Ted) = \dfrac{3}{20}[/tex]

(c) The expected time until all three students are gone is,

[tex]= \dfrac{146}{120} \\\\= 1.22 hours[/tex]

Therefore, the answers are as follows:

(a) 0.45 hours

[tex](b) P(Ron) = \dfrac{7}{12} ,P (Sue) = \dfrac{4}{15} ,P(Ted) = \dfrac{3}{20}\beta[/tex]  

(c)  1.22 hours

Find y

To find y, we make use of the relationship between sides lengths 44 & y and angle 39

The relationship is:

[tex]cos(39) = \frac{44}{y}[/tex]

i.e.

[tex]cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]

To start, make things easier to see by substituting x for sin x. The equation then can be written as 2x^2 + 3x +1. This factors as (2x+1)(x+1). Rewriting in the proper form (2 sin x + 1)(sin x +1). The solutions would be where sin x = -1/2 (7pi/6 and 11pi/6) and sin x = -1 (3pi/2). Choice A

Suppose that in the inventory problem, the storage cost depends on the maximum inventory size, rather than the average. This would be more realistic if, for example, the company had to build a warehouse large enough to hold the maxi- mum inventory, and the cost of storage was the same no matter how full or empty the warehouse was. Show that in this case the number of units that should be ordered or manufactured to minimize the total cost is q= âfM/k

Of means multiply
Is means equals

To change a percent to a decimal move the decimal place tow spots to the left

25% of blank is 21
25% * x = 21
0.25 * x = 21
x = 21 / 0.25
x = 84

Check:
0.25 * x = 21
0.25 * 84 = 21

2x + 8 = -4 solve for c
Show work please

Answers

Answer: x=-6

Step-by-step explanation:

Given

2x + 8 = -4

Subtract 8 on both sides

2x + 8 - 8 = -4 - 8

2x = -12

Divide 2 on both sides

2x / 2 = -12 / 2

x = -6

NOTE: I assume the questions "solve for c" actually means "solve for x"
