The percent frequency distributions of job satisfaction scores for a sample of information systems (IS) senior executives and mi

ddle managers are as follows. The scores range from a low of 1 (very dissatisfied) to a high of 5 (very satisfied).
Job SatisfactionScore - IS SeniorExecutives (%) - IS MiddleManagers (%)
1 - 5 - 2004
2 - 9 - 10
3 - 3 - 12
4 - 42 - 46
5 - 41 - 28

Answer:

a. Probability distribution is given below

Scores Ex, x. 1 2 3 4 5

P(X=x). 0.05 0.09 0.03 0.42 0.41

b. Scores mg, Y 1. 2. 3. 4. 5

P(Y=y). 0.04. 0.1. 0.12 0.46 .28

c. probability that a randomly selected senior executive will report a job satisfaction score of 4 or 5.

P(4 or 5) =p(x=4) +p(x=5)

= 0.42 + 0.41=0.83

Don has 6 pieces of pipe. Each piece is 2 feet 6 inches long.
Alex777 [14]

Answer: 15 feet

Step-by-step explanation:

First you start with 2ft and 6in and convert it all into into inches.

If you know that 1 ft=12in then you know that 2 feet is the same as saying

12+12=24. If you don't understand use this chart-

1 ft=12in

2ft= 24in

3ft= 36in

4ft =48in

5ft= 60in

6ft= 72in

see I am counting by 12's.

Now take 2ft and convert it into inches. That would be 24 in (look in the chart).

now take the 24in(2ft) and add it to the 6in. So 24+6 =30

So now you know that one piece of pipe is 30in long.

But in the text it states that Don has 6 pieces, so...

because it says that he has 6 pieces of pipe then you are going to take that and multiply that number(6) by how long each piece is. look up and it shows how long each pieces is. They are all each 30in long. Take 30 and multiply that by 6 because there are 6 pipes and you will get 120in.

But it says that they need an answer of feet and inches or just feet if it exactly a some sort of foot like 43feet or 2 feet.  

So then we are going to convert 180 into feet by dividing 180 by 12 and you get 15. So the answer is 15.

I hope this helps. Have fun learning!!

At a gas station during a road trip, Gerard has $32.00 to spend on fuel and windshield washer fluid for his car. Fuel costs $2.7
Lemur [1.5K]

Answer:

Step-by-step explanation:

Total amount with Gerald = $32

Cost of fuel per gallon = $2.75

Cost of each bottle of windshield = $3

38 miles per gallon. If Gerard must fill his car with enough fuel to drive 250 miles,

Total gallons of fuel = 250 miles / 38 miles

= 6.5789473684210 gallons

Total cost of fuel = Total gallons of fuel × cost per gallon

= 6.5789473684210 × $2.75

= $18.1

Amount left for windshield = Total amount with Gerald - Total cost of fuel

= $32 - $18.1

= $13.9

what is the maximum number of bottles of windshield washer fluid Gerard can buy?

= Amount left for windshield / Cost of each bottle of windshield

= $13.9 / $3

= 4.6333333333333 bottles

Maximum number of bottles =

4 bottles

Find the zero of polynomial 7x+5
boyakko [2]

Answer:

x=-5/7

Step-by-step explanation:

we have

f(x)=7x+5 ----> The degree of this polynomial is 1 (linear equation)

Remember that

The zero of the polynomial is the value of x when the value of f(x) is zero

so

For f(x)=0

0=7x+5

solve for x

x=-5/7 ----> the zero of the polynomial or x-intercept

I REALLLLLY NEED HELP WITH THAT!!!! Plz help
Inga [223]

Answer:

If it says (10a + 4): 40a + 16

If it says (10a - 4): 40a - 16

Step-by-step explanation:

If it's an equilateral quadrilateral, that means all sides are equal. So you would multiply the given side by the number of sides. Then simplify you equation.

I can't read it if it says (10a + 4) or (10a - 4) so i'll just do both and you can use which one it says.

If it says (10a + 4):

4(10a + 4)

40a + 16

If it says (10a - 4)

4(10a - 4)

40a - 16
