Answer:

a) 1.8

b) 11.8

c) 23.6

(2.4 + 1.6 + 3.2 + 0.3 + 1.5) / 5 = 1.8

(12.4 + 11.6 + 13.2 + 10.3 + 11.5) = 11.8

(24.8 + 23.2 + 26.4 + 20.6 + 23) / 5 = 23.6

or,

11.8 × 2 = 23.6

Answer+Step-by-step explanation:

a)

original mean = (2.4+1.6+3.2+0.3+1.5)÷5

         = 9÷5

         = 1.8

b)

New mean = ((2.4+10)+(1.6+10)+(3.2+10)+(0.3+10)+(1.5+10))÷5

         = (12.4) + (11.6) + (13.2) + (10.3) + (11.5)) ÷ 5

         = 59÷5

         = 11.8

Note:  

11.8-10 = 1.8

then

New mean = original mean + 10

c)

Newest mean = ((2×12.4)+(2×11.6)+(2×13.2)+(2×10.3)+(2×11.5))÷5

                       = ((24.8)+(23.2)+(26.4)+(20.6)+(23))÷5

                       = 118÷5

                       =23.6

Note :

Newest mean = 2×(New mean)

                       = 2×(original mean + 10)

Step-by-step explanation:

270°/360° ×π×13²cm

=398.20cm²

the area of the sector with a radius of 13 units and a central angle of 270 degrees is approximately 398.25 square units.

To find the area of a sector, we use the formula:

Area of sector = (θ/360) * π * r²

Where:

θ is the central angle of the sector in degrees,

r is the radius of the sector.

In this case, the radius (r) is 13 units, and the central angle (θ) is 270 degrees.

Area of sector = (270/360) * π * 13²

Area of sector = (3/4) * π * 169

Area of sector = (3/4) * 169π

Area of sector ≈ 398.25 square units

So, the area of the sector with a radius of 13 units and a central angle of 270 degrees is approximately 398.25 square units.

x-coordinates for the maximum points in any  function  f(x) by f'(x) =0 would be  x = π/2 and x= 3π/2.

To find the maximum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.

we want to find x-coordinates for the maximum points in any  function  f(x) by f'(x) =0

Given f(x)= 4cos(2x -π)

[tex]f'(x) = 0\\- 4sin(2x -\pi ) =0\\\\sin (2x -\pi ) =0 \\2x -\pi = k\pi ... k in Z[/tex]

In general  [tex]x=(k+1)\pi /2[/tex]

from x = 0 to x = 2π :

when k =0  then  x = π/2

when k =1  then x= π

when k =2  then x= 3π/2

when k =3  then x=2π

Thus, X-coordinates of maximum points are  x = π/2 and x= 3π/2

[tex]\displaystyle h(t) = -16t^2 + 35t + 5[/tex]

Step 2: Find Height

Since we are trying to find the height of the basketball at 1 second, it implies that t = 1. Therefore, we can simply substitute t = 1 into our function:

[tex]\displaystyle\begin{aligned}h(1) & = -16(1)^2 + 35(1) + 5 \\& = -16(1) + 35(1) + 5 \\& = -16 + 35 + 5 \\& = \boxed{24} \\\end{aligned}[/tex]

Using the normal distribution, it is found that:

a) The z-score associated with a 60th percentile score is of Z = 0.253.

b) The score associated with the 60th percentile is of 51.265.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 50, \sigma = 5[/tex]

The 60th percentile is X when Z has a p-value of 0.6, so X when Z = 0.253, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.253 = \frac{X - 50}{5}[/tex]

X - 50 = 5(0.253)

X = 51.265.

The height of the kite is  38.042(approx.) and the shadow of kite from Dmitri is 12.36 m (approx.)

The term angle of elevation denotes the angle from the horizontal upward to an object.  An observer’s line of sight would be above the horizontal.

According to the question

Kite string = hypotenuse = 40m

angle of elevation = 72 °

a) Height of kite  = perpendicular

sin( 72 °) = [tex]\frac{Perpendicular}{hypotenuse}[/tex]

0.951  =  [tex]\frac{Perpendicular}{40}[/tex]

38.042 ≈ Perpendicular or Height of kite  ≈ 38.042

b) Sun is directly above the kite , kite's shadow from Dmitri is = base

Tan (72°) = [tex]\frac{perpendicular }{base}[/tex]

3.077   =  [tex]\frac{38.042 }{base}[/tex]

Base ≈  12.36 m

Hence, height of the kite is  38.042(approx.) and the shadow of kite from Dmitri is 12.36 m

The sets of numbers which could represent the three sides of a triangle is {6,14,17}. Option A is the correct option.

Triangle inequality theorem of a triangle says that the sum of the two sides of a triangle is always greater than the third side.

Suppose a, b and c are the three sides of a triangle. Thus, according to this theorem,

[tex](a+b) > c\\(b+c) > a\\(c+a) > b[/tex]

The sides of first option are, 6,14,and 17.

[tex]6+14 > 17\\20 > 17[/tex]

2.7 * 10^3 is < 27 * 10^3

since

27 * 10^3 = 27000

2.7 * 10^3 = 2700

2700 < 27000

now since multiplying by 10 moves the decimal to the right, just looking and mentally comparing them. since they are both multiplied by 10^3 you're left with 2.7 and 27

Answer: the answer is choice b

Step-by-step explanation:

Answer:

Top Left (<A) = 86 degrees // Top Right (<B) = 112 degrees // Bottom Left (<C) = 68 degrees // Bottom Right (<D) = 94 degrees

Step-by-step explanation:

So with inscribed quadrilaterals opposing corners are supplementery. This means they will add to 180 degrees. So first what we can do is set (x + 2) and (x - 6) equal to 180 ----> 2x - 4 = 180 ----> 2x = 184 ----> x = 92

So if x = 92 then <A = 86 degrees //// <B = 112 degrees //// <C must equal 68 degrees because <B and <C are supplementery //// <D = 94 degrees
