Given:

The data set is:

68, 74, 67, 72, 63, 70, 78, 64, 76

To find:

The median, first quartile, third quartile, and interquartile range of the data.

Solution:

We have,

68, 74, 67, 72, 63, 70, 78, 64, 76

Arrange the given data in ascending order.

63, 64, 67, 68, 70, 72, 74, 76, 78

Now divide the data in two equal parts.

(63, 64, 67, 68), 70, (72, 74, 76, 78)

So, the median of the given data set is 70.

Divide each parenthesis in two equal parts.

(63, 64), (67, 68), 70, (72, 74), (76, 78)

Now, the first quartile is:

[tex]Q_1=\dfrac{64+67}{2}[/tex]

[tex]Q_1=\dfrac{131}{2}[/tex]

[tex]Q_1=65.5[/tex]

The third quartile is:

[tex]Q_3=\dfrac{74+76}{2}[/tex]

[tex]Q_3=\dfrac{150}{2}[/tex]

[tex]Q_3=75[/tex]

The interquartile range (IQR) is the difference between third quartile and first quartile.

[tex]IQR=75-65.5[/tex]

[tex]IQR=9.5[/tex]

Therefore, median is 70, first quartile is 65.5, third quartile is 75 and the interquartile range is 9.5.

115 divided by 6 is 19.16

A division is a process of splitting a specific amount into equal parts.

We need to find the solution or quotient when 115 is divided by six.

115 is the dividend.

6 is the divisor.

115/6

115 is the numerator and six is the denominator.

19.16 is the solution when 115 divided by 6 i

Hence, 115 divided by 6 is 19.16

Answer:

-16(5/8)^ 2 + 20(5/8) + 6  =   12.25  ft

Step-by-step explanation:

h = -16t^ 2 + 20t + 6  the ball will hit the ground when h  = 0

0 = -16t^2  + 20t   + 6      factor

0  = ( -8t  -  2 )  ( 2t  - 3)     set each  factor to 0                        

-8t  -  2  =  0   and   2t  - 3   = 0

-8t   = 2             2t   =   3

t  = -2/8  = - 1/4  sec        t  = 3/2 sec  = 1.5 sec

Max hit will be reached at [ -b / 2a ]    sec    =  -20 / [ 2(-16)]  =  20/32  =  5/8 sec

 -16(5/8)^ 2 + 20(5/8) + 6  =   12.25  ft

Answer:

1/2

Step-by-step explanation:

D'après la question ci-dessus, on nous dit que:

La boîte à linge de Killian est remplie aux 2/3.

Il utilise un quart de ce qui reste dans le conteneur pour laver ses vêtements.

La fraction de ce qu'il utilisait pour laver ses vêtements =

1/4 sur 2/3

= 1/4 × 2/3

= 1/6

La quantité de détergent qu'il reste dans le récipient est calculée comme suit:

2/3 - 1/6

Dénominateur commun le plus bas = 6

2 × 2 - 1 × 1/6

4 - 1/6

= 3/6

= 1/2

Answer:

9, y=9

Step-by-step explanation:

So, there is one thing we always need to remember to find the y intercept.

This is that the y intercept can always be found on the middle line of the graph, when x is at 0.

What we must do is look at the graph, look at where the function hits x=0, and see what the y value is.

In this case, when x equals 0, we can see that y is 9.

So the y intercept is 9.

Hope this helps! :D

Answer: y = 2x + 8/3

Step-by-step explanation:

6x - 3y +8 = 0

-3y + 8 = -6x

-3y = -6x - 8

y = 2x + 8/3

Answer:

y = 2x + 8/3

Step-by-step explanation:

slope y-intercept form => y = mx + b

=> -3y = -6x - 8

=> y = 2x + 8/3

Answer:

Option B.

Step-by-step explanation:

For a function f(x), the domain is the set of all the possible values of x that can be used in the function.

We know that the natural logarithm is only defined for positive real numbers.

So, the function:

Ln(x + 2)

Works always that

x + 2 > 0

So we can just solve this inequality for x, and that will give us the domain of the function.

To isolate x, we just need to subtract 2 in both sides of the inequality.

x + 2 - 2 > 0 - 2

x > - 2

This is the domain of the function.

The correct option is B.

Answer:

47.7° or 132.3°

Step-by-step explanation:

In A ABC, m B = 25°, b = 12 and c = 21. Find all possible mC to the

nearest degree.

We solve the above question using Laws of sines.

The formula is given as

b/sin B = c/sin C

b = 12

B = 25°

c = 21

C = ?

Hence:

12/sin 25 = 21/sin C

Cross Mulitiply

= 12 × sin C = sin 25 × 21

sin C = sin 25 × 21/12

C = arc sin (sin 25 × 21/12)

C = 47.7°

The second possible value of C =

180° - 47.7°

= 132.3°

Therefore, all the possible values of mC = 47.7° or 132.3°

Answer:

f(x) = 4 reflected over y- axis is g(x)= -4

change the sigh of x.

The function that represents a reflection of f(x) = (4) across the y-axis is g(x) = -4.

A reflection across the y-axis will result in a mirror image of the original function. This means that any points on the right side of the y-axis will be reflected to the left side, and vice versa.

Start with the original function f(x) = (4). This function represents a horizontal line at y = 4.

To reflect the function across the y-axis, we need to change the sign of the x-coordinates of all the points. If a point on the original function is (x, y), the corresponding reflected point will be (-x, y).

Applying this reflection to the original function f(x) = (4), we get g(x) = -(4). The negative sign indicates the reflection across the y-axis.

Simplifying the function, we have g(x) = -4.

Therefore, the function that represents a reflection of f(x) = (4) across the y-axis is g(x) = -4.
