THE ONLY STATEMENT THAT IS FALSE IS THE NUMBER 5.

Step-by-step explanation:

Table of ordered data

number of       value

data

1                      62

2                      88

3                      89

4                      90

5                      92

6                      95

7                      96

8                      98

9                    100

10                  100

Range of scores: 100 - 62 = 38

Oulier: 62 => Range without the outlier = 100 - 88 = 12

Interquartile range, IQR, = difference between third quartile and first quartile: IQR = Q3 - Q1

Quartlies of all the data:

1                      62

2                      88

3                      89 ---------------   first quartile, Q1 = 89

4                      90

5                      92

------------------------------------------ median, Q2 = (95 + 92) / 2 = 93.5

6                      95

7                      96

8                      98 ---------------- third quartile, Q3 = 98

9                    100

10                  100

=> IQR = 98 - 89 = 9 : the interquartle range is 9

Quartlies without the outlier:

2                      88

3                      89

------------------------------------- first quartile, Q1 = (89 + 90) / 2 = 89.5

4                      90

5                      92

6                      95 --------------- median, Q2 = 95

7                      96

8                      98

------------------------------------ third quartile, Q3 = (98 + 100) / 2 = 99

9                    100

10                  100

=> IQR = Q3 - Q1 = 99 - 89.5 =  : the interquartle range without the outlier is 9.5

Therefore, the outlier impacts more the range than it impacts the IQR.

Answer:

192 cm3

Step-by-step explanation:

The volume of any pyramid is 1/3 × b × h, where b =  area of base of the pyramid and h = height of the pyramid.

Area of Base:

Now, we multiply 24 by 24.

Lastly, we divide by 3.

Therefore, the answer is 192 cm^3.

Answer:

50.5 m^3

Step-by-step explanation:

Volume of pyramid = 1/3 × base area × height.

Area of Base:

Next, we multiply 13.76 by 11.

Lastly, divide by 3 and round to nearest tenth.

Therefore, the answer is 50.5 m^3

It will take 5 hours to pump 60000L of water using 9 pumps

Data;

Rate = Time * number of pumps

[tex]\frac{a}{3*10} = \frac{60000}{40000}\\ \frac{a}{30} = \frac{6}{4} \\a = 45[/tex]

But since we've established the equation above, let's substitute the values and solve for the time required to pump 60000L into the dam using 9 pumps as compared to 10 pumps. We can easily do this by calculating the rate of the pump.

Rate = time * number of pumps

[tex]45=x*9\\x = \frac{45}{9} \\x = 5 hours[/tex]

Step-by-step explanation:

The grid lines are 1 unit apart, so you can determine the dimensions of the trapezoid by counting grid squares. The parallel bases have lengths 6 and 2. They are 5 units apart.

The area is given by ...

  A = 1/2(b1 +b2)h

  A = 1/2(6 +2)(5) = 20

The area of the trapezoid is 20 square units.

Answer:

$20

Step-by-step explanation:

if one ound = 16 ounces then you would do 1.25x16 witch equals $20

If oranges were 1.25$ per pound. then the cost to buy x pounds of oranges would be 1.25x $.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

If oranges were 1.25$ per pound. We need to find the cost to buy x pounds of oranges.

The cost of oranges per pound = 1.25$

The cost of oranges x pound = 1.25$ × x

                                                 = 1.25x $

Thus, The cost to buy x pounds of oranges would be 1.25x $.

Step-by-step explanation:

the equation for right cylinder surface area: 2πrh+2πr^2

Answer:

33π cm²

Step-by-step explanation:

To find surface area you add the area of every face.

Area of the 2 circle faces:

The formula for the area of circle is πr². If the diameter is 6 you divide that by 2 to get a radius of 3. The area of the circle is 9π. Sense the top and bottom are both circles you multiply the area by 2 to get 18π.

Area of side face:

To find the area of the side, it is the same as a rectangle (length [circumference] multiplied by height [2.5]). The forumla for the circumference of a circle is πd. The circumference is 6π so multiply that by the height of 2.5 to get the area of the side of 15π.

Total surface area:

Now add the 18π (area of 2 circle faces) with the 15π (area of side face) to get 33π cm² surface area.

Answer:

B

Step-by-step explanation:

x² - 12x + 11 = 0 ( subtract 11 from both sides )

x² - 12x = - 11

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 6)x + 36 = - 11 + 36

(x - 6)² = 25 ( take square root of both sides )

x - 6 = ± [tex]\sqrt{25}[/tex] = ± 5 ( add 6 to both sides )

x = 6 ± 5

Then

x = 6 - 5 = 1 ⇒ (1, 0 )

x = 6 + 5 = 11 ⇒ (11, 0 )
