A total of 500 married working couples were polled about their annual salaries, with the following information resulting: Husband Wife Less than More than $25,000 $25,000 Less than $25,000 212 198 More than $25,000 36 54 For instance, in 36 of the couples, the wife earned more and the husband earned less than $25,000. If one of the couples is randomly chosen, what is (a) the probability that the husband earns less than $25,000

Answers

Answer 1

Answer:

36/500

Step-by-step explanation:

Answer 2

The probability that the husband earns less than $25,000 is 0.496.

Given that,

A total of 500 married working couples were polled about their annual salaries, with the following information resulting:

                                              Husband

Wife                                       Less than $25,000   More than $25,000

Less than $25,000              212                               198

More than $25,000              36                                 54

Thus, for instance, in 36 of the couples, the wife earned more and the husband earned less than $25,000. If one of the couples is randomly chosen.

We have to determine,

What is the probability that the husband earns less than $25,000?

According to the question,

The probability that the husband earned less than $25,000 is,

Total number of couples = 500

The count of husbands earning less than $25,000 is 212 and 36.

[tex]\rm Probability = \dfrac{Total \ number \ of \ couples}{Husband \ earn \ less \ than \ 25000}\\\\ Probability= \dfrac{212+36}{212+36+198+54}\\\\Probability = \dfrac{246}{500}\\\\Probability = 0.496[/tex]

Hence, The probability that the husband earns less than $25,000 is 0.496.

A health club charges $250 to become a member and an additional $25 per month. Assuming no other charges, what is the total cost of the first full membership

Answers

Answer:

$275

Step-by-step explanation:

I am 100% sure that $275 would be for the first cost of the month. if its monthly then you times that by 12 to get 3,300 which would be the cost for the year.

The answer is 275

That’s the answer because:
This problem can be made into
25x+250
Where x is the number of months
So if they stayed for a month it would be
25(1)+250
25*1 is 25
25+250 is 275

Sample IQR will change

Range, IQR, and standard deviation will remain the same

Sample range will change.

Sample standard deviation will change

Answer:

Sample range will change

Sample Standard deviation will change

Step-by-step explanation:

Given the sorted sample : 0,0,3, 4,5,8,10, 18

n = number of observations

Sample range : ( 18 - 0) = 10

Upper quartile (Q3) = 3/4(n+ 1) = 3/4(9) th term

Q3 = 27/4 = 6.75th term

(8 + 10) / 2 = 18/ 2 = 9

Lower quartile (Q1) = 1/4(n + 1) = 9/4 th term

2.25th term = 0+3 = 3/2 = 1.5

Interquartile range = 9 - 1.5 = 7.5

Standard deviation = 5.976 (using calculator)

If 18 is replaced by 20:

0,0,3, 4,5,8,10, 20

Range = (20 - 0). = 20

Upper quartile (Q3) = 3/4(n+ 1) = 3/4(9) th term

Q3 = 27/4 = 6.75th term

(8 + 10) / 2 = 18/ 2 = 9

Lower quartile (Q1) = 1/4(n + 1) = 9/4 th term

2.25th term = 0+3 = 3/2 = 1.5

Interquartile range = 9 - 1.5 = 7.5

Standard deviation = 6.563 (using calculator)

Tyler claims that because he started painting first he will finish painting his side of the fence before Benito finishes painting his side. Is this true? Explain

Answers

Answer:

but

Step-by-step explanation:

yrge sksue dnd djd d d. r e g g h a s. v j u r d. d c g y t

Tyler's claim about finishing his painting first is False because it will take Benito 10 minutes while Tyler will require over 11 minutes to finish up his painting despite starting before Benito.

Size of fence = 150 feet

Benito's rate = 15 ft/min

Tyler's rate = 11 ft/ min

Size already painted by Tyler when Benito started = 39/2 = 19.5 ft

Portion of fence left for Tyler to paint when Benito started = (150 - 19.5) = 130.5 feets

Time required for Tyler to finish :

Time required = 130.5 ÷ 11 = 11.863 minutes

Time required for Benito to finish :

Time required = 150 ÷ 15 = 10 minutes

Time required for Benito to complete his painting is lesser than Tyler's (10 < 11.863)

Hence, Tyler's claim is False

Answers

Answer:

324

Step-by-step explanation:

L = 4W

P = 2L + 2W = 90

---

2L + 2W = 90

2(4W) + 2W = 90

8W + 2W = 90

10W = 90

---

W = 9

L = 36

---

 

A = 324

---

Answer:

The area of the rectangle is 324 square centimeter.

Step-by-step explanation:

What is area?

The area is the amount of space within the perimeter of a 2D shape.

What is rectangle?

A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.

What is perimeter?

Perimeter is the distance around the edge of a shape.

Let the width of the rectangle be x cm.

Then, the length of the rectangle = 4xcm

Perimeter  = 2(length + breadth )

90 = 2(4x+x)

90 = 2*5x

90 = 10x

x = 90/10= 9cm

Width = 9cm

Length = 4*9 = 36 cm

Area = Length*Breadth

       =9*36

      =324 square centimeter.

80.4

Step-by-step explanation:

You have to first find the area of the circle which the formula for that is pi r^2. So you would set it up as 3.14 (2.5)^2 which you then would solve and get 19.625. Then, you find the area of the square which is length times width. So then you would multiply 10 and 10 and get 100. You then subtract 100 and 19.625 which gives you 80.375 but since it says round to the nearest tenth you'd get 80.4.

Step-by-step explanation:

For no.1

sloution,

for small

[tex]r = 2.5[/tex]

[tex]\pi = 3.14[/tex]

Area(A1)=?

now,

A = π r²

A=3.14*2.5^2

A=19.6

A1=19.6cm^2

For,big square

L=10cm

A2=?

now,

A=L^2

A=10^2

A=100

A2=100cm^2

For shaded area

A=A2-A1

A=100-19.6
