Step-by-step explanation:

Answer:

16.97

Step-by-step explanation:

the geometric mean value of a set of n numbers is the nth root of the product of all n numbers.

so, here this means

[tex]gm = \sqrt[6]{3 \times 6 \times 12 \times 24 \times 48 \times 96} [/tex]

this would be 16.97

but careful, the problem only asks for the gm between 6 and 48 of the sequence.

so, we actually only consider the subset 6, 12, 24, 48.

therefore

[tex]gm = \sqrt[4]{6 \times 12 \times 24 \times 48} [/tex]

this is also

[tex]gm = \sqrt[4]{3 \times 2 \times 3 \times 2 \times 2 \times 3 \times 2 \times 2 \times 2 \times 3 \times 2 \times 2 \times 2 \times 2} [/tex]

[tex] = \sqrt[4]{ {3}^{4} \times {2}^{10} } [/tex]

[tex] = \sqrt[4]{ {3}^{4} \times {2}^{4} \times {2}^{4} \times {2}^{2} } [/tex]

[tex] = 3 \times 2 \times 2 \times \sqrt[4]{ {2}^{2} } [/tex]

[tex] = 12 \times \sqrt{2} [/tex]

so, we could specify the result as that simple expression

or calculate it

gm = 16.97

hey, the result is the same as for the complete sequence.

coincidence ? no, it is not. but that is a subject for a different question.

Answer: 72

Step-by-step explanation:

30+48=78

√78^2-30^2=

√5184=

72

If AO = 30, BC = 48 then, AB = 72.

"Tangent to a circle is the line that touches the circle at only one point."

"A tangent to a circle is always perpendicular to the radius of a circle."

For given question,

AB is tangent to circle.

Also, AO = 30, BC = 48

From figure, we can observe that,

AO = CO                            .......................(radius of circle)

⇒OC = 48

Also,

OB = OC + BC

⇒ OB = 30 + 48

⇒ OB = 78

We know, a tangent to a circle is always perpendicular to the radius of a circle.

⇒ AB ⊥ AO

This means, ΔAOB is right triangle.

Using Pythagoras theorem to right triangle AOB,

⇒ [tex](OB)^{2} = (AO)^{2} + (AB)^{2}[/tex]

⇒ [tex](AB)^2 = (OB)^{2} - (AO)^{2}[/tex]

⇒ [tex](AB)^2=(78)^2-(30)^2[/tex]

⇒ [tex](AB)^2=5184[/tex]

⇒ [tex]AB=\sqrt{5184}[/tex]

⇒ [tex]\bold{AB=72}[/tex]

Therefore, option (D) is the correct answer.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Perimeter: 8cm + 8cm + 3cm + 3cm = 22cm

Area: 8cm x 3cm = 24cm

2. Perimeter: 5m + 5m + 5m + 5m = 20m

Area: 5m x 5m = 25m

3. Perimeter: 4m + 4m + 18m + 18m = 44m

Area: 4m x 18m = 72m

Answer:

The correct answer is option B 12cm

Answer:

1. 96

2. x= 10.909 (10.91 (rounded))

Step-by-step explanation:

1. You can break the figure into 3 parts, a triangle and 2 rectangles

For the triangle, we have this information:

height is 3

length is 8

angle is 90 (right angle)

area = 0.5 * 3 * 8 * sin(90)

area is 12

For the two rectangles, just multiply the length * width

5 * 4= 20

8 * 8= 64

Then add them ALL together

12 + 20 + 64 = 96

2. x = √(12^2 - 52^2)

x= 10.09

(10.91(rounded))

Step-by-step explanation:

A scatterplot shows the number of miles driven versus the gallons of gasoline remaining in the gas tank of a car. Which correlation best describes the relationship shown on the scatterplot?

Answer:

Negative correlation

Step-by-step explanation:

The kind of relationship which exists between two variables can be obtained whwn plotted in a graph such that we can visually access the data and note its trend. Datasets with fit lines trending downward will always have a slope value which is negative. In the scenario above, gallon of gasoline falls as the number if miles driven increases. This is a very reasonable relationship. And thus correlation between Both variables will be negative

Answer:

14.14

Step-by-step explanation:

Recall :

The sides of a square are always equal ;

Since all sides are equal, the the diagonal of the square will be :

XZ² = XY² + WX²

XZ² = 20² + 20²

XZ² = 400 + 400

XZ² = 800

XZ = √800

XZ = 28.28

WY = XZ

WV = 1/2 WY

WV = 1/2 * 28.28

WV = 14.14
