Answer:

1. e ≥ -2

2. c ≤ 4

3. x < 1.5 or 1 5/10

Step-by-step explanation:

1.  -3e-10 ≤ -4  => first add 10 to both sides

     +10    +10

-3e ≤ 6 => Then divide negative three on both sides.

/-3    /-3

e ≥ -2 => Since, we divided by a negative the sign switches.

2.  8c+4 ≤ 4(c-3) => First, Distribute the 4.

8c+4 ≤ 4c -12 => Next, Subtract 4 on both sides.

8c ≤ 4c -16 => then, subtract 4c on both sides.

-4c   4c

4c ≤ 16 => Finally, you divided 4 on both sides.

/4    /4

c ≤ 4

3. 5(x-1) < 3x +10 -8x => First, you add like terms.

5(x -1) < -5x +10 => Next, you distribute the 5.

5x -5 < -5x +10 => Then, you add five in both sides.

    +5      +5

5x < -5x +15 => After that you add -5x in both sides.

+5x   +5x

10x < 15 => Finally, you divide 10 in both sides.

/10     /10

x < 1.5 or 1 5/10

Dr. Jones is interested in expanding his practice by adding a piece of radiology equipment. The basic cost of the equipment woul
inysia [295]

Answer:

<u>Dr. Jones' projected income is US$ 56.793, projected costs are US$ 61,935.48 and projected loss is US$ 5,142.48 for the 1st year of the radiology service.</u>

Step-by-step explanation:

1. Dr. Jones Income per year:

Income = 1,100 * 51.63

<u>Income = US$ 56,793</u>

<u>2. Dr. Jones Costs</u>

Equipment = US$ 1,564.29 loan cost monthly

Radiology tech salary = US$ 39,600 (including taxes and fringe benefits)

Variable cost = US$ 3.24 * 1,100

Equipment = 1,564.29 * 12 = US$ 18,771.48

Radiology tech salary = US$ 39,600

Variable cost = US$ 3,564

Total costs = Equipment loan cost + Radiology tech salary + Variable cost

Total costs = 18,771.48 + 39,600 + 3,564

<u>Total costs = US$ 61,935.48</u>

<u>3. Dr. Jones Profit or Loss</u>

Profit or loss = Income - costs

Profit or loss = 56,793 - 61,935.48 (Costs are higher than income)

<u>Loss = US$ 5,142.48</u>

The R.D. Wilson Company makes a soft drink dispensing machine that allows customers to get soft drinks from the machine in a cup
Vanyuwa [196]

Answer:

B) The null hypothesis cannot be rejected since the test statistic is approximately t = .29,which is not in the rejection region.

Step-by-step explanation:

to calculate mean

14.25+ 13.7 +14.02 +14.13+ 13.99 +14.04

= 84.13/6

= 14.02167

average = 14

s = 0.1837

test statistics t:

(bar(x)-mu)/(s/√n)

= 14.02167-14/0.1837/√6

0.02167/0.1837/2.4495

= 0.02167/0.07499

=0.28897

this is approximately 0.29

<u>therefore B) The null hypothesis cannot be rejected since the test statistic is approximately t = .29,which is not in the rejection region.</u>
