The mean and the average values are the same. They represent a dataset by calculating the central value.

The range can be understood as the variation of the data. The higher the range, the wider the variation.

From the table, we can see the average temperature of Rio de Janeiro is higher than in Caracas.

We can also see the variation of the temperature is higher in Caracas than in Rio de Janerio.

This corresponds to choice A.

Answer: h = b/A

Explanation: If i hit 5 out of 10 balls thrown, my batting average is 2.

.5 = 5/10.

If my batting average is .5, and 10 balls were thrown, I only hit half or 5 of them. 5 = 10/.5

Solution

otal number of cCustomer = 11 + 9 + 11 + 5 + 5 + 1 + 3 = 45

hus, the probability is 0.556

Option D

The number which is decreased by 20% and result is 336 then number is 420

According to the question, given that

when a number is decreased by 20 % of itself, it became 336

then, the number is :

x - (x ×[tex]\frac{20}{100}[/tex] )= 336

x - [tex]\frac{x}{5}[/tex] = 336

[tex]\frac{5x - x}{5}[/tex] = 336

[tex]\frac{4x}{5}[/tex] = 336

x = [tex]\frac{336 *5}{4}[/tex]

x = 84 * 5

x = 420

Therefore, we get the number is 420

PERCENT INCREASE =(new amount−original amount)/original amount

Some people append 100% at the end of this calculation to stress that it should be stated as a percent since it represents an increase in percentage.

So, as an alternative, here is the formula:

PERCENT INCREASE = (new amount−original amount)/original amount*100%

PERCENT DECREASE=(original amount−new amount)original amount

OR

PERCENT DECREASE=(original amount−new amount)original amount*100%

Both formulas have the following pattern:

PERCENT INCREASE/DECREASE=change in amount /original amount

OR

PERCENT INCREASE/DECREASE=change in amount/ original amount*100%

The value of x in the given right triangle is 8√5.

Pythagoras theorem states the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

The length of side z of the triangle is calculated as follows;

z² = y² + 4²

The length of side x is calculated as follows;

x² + z² = (16 + 4)²

x² + z² =  20²

substitute the value of z² into the equation,

x²  + y² + 4² = 20²

x²  + y² = 20² - 4²

x²  + y² = 384

Considering the second triangle, with sides, 16, x and y, the value of side y is calculated as follows;

y² = x² - 16²

y² = x² - 256

x²  + y² = 384

x²  + x² - 256 = 384

2x² = 384 + 256

2x² = 640

x² = 640/2

x² = 320

x = √320

x = √(64 x 5)

x = √64 . √5

The perimeter of the hexagon ABCDEF is 36.01.

Given,

The hexagon ABCDEF

We have given the points:

A(-6, 2), B(1, 5), C(6, 5), D(6, -1), E(1, -3), F(-6, -3)

We have to find the perimeter of hexagon.

Perimeter of hexagon = AB + BC + CD + DE + EF + FA

Now,

Distance formula is as [tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

So,

A(-6, 2), B(1, 5) : x₁ = 1, x₂ = -6, y₁ = 2, y₂ = 5

[tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

= [tex]\sqrt{(1-(-6))^{2} +(5-2)^{2} }[/tex]

=[tex]\sqrt{7^{2} +3^{2} }[/tex]

= [tex]\sqrt{49+9}[/tex]

= √58

= 7.62

B(1, 5), C(6, 5) : x₁ = 1, x₂ = 6, y₁ = 5, y₂ = 5

[tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

= [tex]\sqrt{(6-1)^{2}+(5-5)^{2} }[/tex]

= √5²

= 5

C(6, 5), D(6, -1) : x₁ = 6, x₂ = 6, y₁ = 5, y₂ = -1

[tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

= [tex]\sqrt{(6-6)^{2}+(-1-5)^{2} }[/tex]

= √-6²

= 6

D(6, -1), E(1, -3) : x₁ = 6, x₂ = 1, y₁ = -1, y₂ = -3

[tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

= [tex]\sqrt{(1-6)^{2}+(-3-(- 1))^{2} }[/tex]

= [tex]\sqrt{(-5)^{2} +(-3+1)^{2} }[/tex]

= [tex]\sqrt{25 + 4}[/tex]

= √29

= 5.39

E(1, -3), F(-6, -3)  : x₁ = 1, x₂ = -6, y₁ = -3, y₂ = -3

[tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

= [tex]\sqrt{(-6-1)^{2}+(-3-(-3))^{2} }[/tex]

= √-7²

= 7

F(-6, -3), A(-6, 2)  : x₁ = -6, x₂ = -6, y₁ = -3, y₂ = 2

[tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

So, we have

AB = 7.62

BC = 5

CD = 6

DE = 5.39

EF = 7

FA = 5

Now,

Perimeter of hexagon = AB + BC + CD + DE + EF + FA

Perimeter of hexagon= 7.62 + 5 + 6 + 5.39 + 7 + 5

Let the number of days be represented by x

Let the intial height of the zucchini plant be g₀

g₀ = 10 cm

Size of growth per day = 0.5 cm

Let the growth after x days be represented by g(x)

a) The rule that represents the function is therefore:

g(x) = g₀ + 0.5x

g(x) = 10 + 0.5x

b) After how many days will the Zucchini pant be 0.185 meters tall

That is g(x) = 0.185 meters

since 1 meter = 100 cm

g(x) = 0.185 x 100 cm

g(x) = 18.5 cm

Thereofre substitute g(x) = 18.5 into the equation g(x) = 10 + 0.5x

18.5 = 10 + 0.5x

18.5 - 10 = 0.5x

0.5x = 8.5

x = 8.5 / 0.5

After evaluting the  expression 8+ 9/4 (-2) we get 8 1/4.and result in decimals: 8.25

Given expression -

8+ 9/4 (-2) = ?

Combine the whole numbers and fractions together:

(8 – 2) + (9/4 - 0)

The whole numbers part is:

8 – 2 = 6

For the fractions part:

(9/4 - 0)

The Least Common Multiple (LCM) of 4 and 1 is 4. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:

9/4 - 0 = 9/4 - 0/4

Now that the fractions have like denominators, subtract the numerators:

9 - 0/4 = 9/4

9 ÷ 4 = 2R1, therefore

9/4 = 2 1/4

Put the whole number and fraction together:

6 +2(1/4) 1

8 1/4.

Hence , the result of the expression 8+ 9/4 (-2) = 8 1/4.

The description of the motion of the ball, which is a projectile are as follows;

(a) The window coordinates are; (0, 138.49)

(b) The x–component is 7.22 m)s

The y–component is -3.22 m/s

(c) The equations for displacement are;

(d) 16.07 m from the base

(e) Height of the ball location before it was thrown is 138.49 meters

(f) Time to reach 10.0 m. is 1.14 s

Projectile motion is the motion of an object that is thrown or thrusted into the air such that the major force acting on an object is the force of gravity

(a) The parameters of the motion of the ball are;

Initial velocity of the ball = 7.8 m/s

Direction to which the ball is tossed = 24° below the horizontal

Time it takes the ball to strike the ground = 5.00 s

Location of the origin of the coordinates = The base of the building

[tex]h = v_{iy} \cdot t + 0.5 \cdot g \cdot t²[/tex]

Where;

h = The height of the window

[tex]u_{y}[/tex]

The initial vertical velocity = 7.8×sin(24°) ≈ 3.173 m/s

g = The acceleration due to gravity ≈ 9.81 m/s²

t = The time duration of the motion = 5.00 s

Therefore;

h = 3.173×5 + 0.5×9.81×5²≈ 138.49

The height of the window, h ≈ 138.49 meters

Given that the window shares the same x–coordinates with the base, which is 0, we have;

(b) The x and y–component of the initial velocity are therefore;

v = 7.9 m/s × (cos(24°)•i - sin(24°)•j)

v = 7.22•i - 3.21•j

The x and y component of the velocity are therefore

x–component [tex] v_{ix} [/tex] = 7.22•i

y–component, [tex] v_{y} [/tex] = -3.21•j

Therefore;

(c) The equation of the x–component of the position is found as follows;

x = 7.9×cos(24°) × t = 7.22 •t

y = 7.9×sin(24°) × t+ 0.5× 9.81×t²

(d) The distance from the base of the building where the ball lands is given by the equation

d ≈ 3.21 × 5 ≈ 16.07

(e) The height from which the ball was thrown, h, is given by the y–coordinate in option (a) therefore;

(f) When the distance traveled = 10 meters, we have;

[tex]h = v_{iy} \cdot t + 0.5 \cdot g \cdot t²[/tex]

Which gives;

10 = 3.21•t + 0.5×9.81×t²

Solving with a graphing calculator, gives;

t ≈ -1.79 or t = 1.14

x^2 + 20 = 9 x + 2

Subtract 9 x + 2 from both sides:

x^2 - 9 x + 18 = 0

The left-hand side factors into a product with two terms:

(x - 6) (x - 3) = 0

Split into two equations:

x - 6 = 0 or x - 3 = 0

Add 6 to both sides:

x = 6 or x - 3 = 0

Add 3 to both sides:
