kelly will roll a number cube labeled 1 to 6. what is the probability kelly will roll a number greater than 3?

Step-by-step explanation:

For y = 2^x:

f(-3) = 2^-3. f(-2) = 2^-2. f(-1) = 2^-1

= 1/8 = 1/4. =1/2

f(0) = 2^0 f(1) = 2^1. f(2) = 2^2

= 1 = 2. =4

f(3) = 2^3

=8

For 3y = 7x + 3, y= (7x+3)/3

f(-3) = [7(-3)+3] / 3. f(-2) = [7(-2)+3] / 3

= -6. = -11/3

f(-1) = [7(-1)+3] / 3. f(0) = [7(0)+3] / 3

= -4/3 = 1

f(1) = [7(1)+3] / 3. f(2) = [7(2)+3] / 3

= 10/3 = 17/3

f(3) = [7(3)+3] / 3.

= 8

point of intersection, where y=2^x and 3y = 7x + 3 has the same x and y coordinate

Answer: (0,1) and (3,8)

Answer:

(2x + y)*5

Step-by-step explanation:

Translating the word problem into an algebraic expression, we have;

(2x + y) * 5

Simplifying an expression simply means to collect like terms that are having the same variables or constants and combining them, so as to reduce the expression to the lowest possible value.

Simplifying further by opening the bracket, we have;

(2x + y)*5 = 10x + 5y

Answer:

Perimeter of JKL = 22.55 unit (Approx.)

Step-by-step explanation:

Given:

Coordinate of J = (2,3)

Coordinate of K = (10,4)

Coordinate of L = (6,10)

Find:

Perimeter of JKL

Computation:

Distance = √(x1 - x2)² + (y1 - y2)²

Distance between JK = √(2 - 10)² + (3 - 4)²

Distance between JK = √64 + 1

Distance between JK = √65

Distance between JK = 8.06 unit

Distance between KL = √(10 - 6)² + (4 - 10)²

Distance between KL = √16 + 36

Distance between KL = √52

Distance between KL = 7.21 unit

Distance between LJ = √(6 - 2)² + (10 - 3)²

Distance between LJ = √4 + 49

Distance between LJ = √53

Distance between LJ = 7.28 unit

Perimeter of JKL = Distance between JK + Distance between KL + Distance between LJ

Perimeter of JKL = 8.06 + 7.21 + 7.28

Perimeter of JKL = 22.55 unit (Approx.)

Answer:

Total surface area = 434 cm²

Total volume = 470 cm³

Step-by-step explanation:

1. The prism can be decomposed into two rectangular prisms which are the bigger rectangular prism and the smaller rectangular prism

✔️Total surface area of the prism = (surface area of the bigger prism - area of the face joined to the smaller prism) + (surface area of the smaller prism - area of the face joined to the bigger prism)

Surface Area of bigger prism = 2(LW + LH + HW)

L = 10 cm

H = 8 cm

W = 9 - 5 = 4 cm

Area of bigger rectangular prism = 2(10*4 + 10*8 + 8*4)

= 304 cm²

Surface area of the smaller prism = 2(LW + LH + HW)

L = 10 cm

H = 3 cm

W = 5 cm

Area of bigger rectangular prism = 2(10*5 + 10*3 + 3*5)

= 190 cm²

Area of the face joining both rectangular prisms = L*W

L = 10 cm

W = 3 cm

Area = 10*3 = 30 cm²

✅total surface area of the prism = (304 - 30) + (190 - 30) = 274 + 160 = 434 cm²

2. Volume of the prism = volume of the bigger rectangular prism + volume of the smaller rectangular prism

✔️Volume of the bigger rectangular prism = L*W*H

L = 10 cm

H = 8 cm

W = 9 - 5 = 4 cm

Volume = 10*8*4 = 320 cm³

✔️✔️Volume of the bigger rectangular prism = L*W*H

L = 10 cm

H = 3 cm

W = 5 cm

Volume = 10*3*5 = 150 cm³

✅Total Volume of the prism = 320 + 150 = 470 cm³

Answer:

Surface area of the given pyramid = 386.16 cm²

Step-by-step explanation:

Surface area of the given pyramid = Area of the square base + Area of the lateral sides

Area of the square base = (Side)²

                                        = (12)²

                                        = 144 cm²

Area of the lateral side = [tex]\frac{1}{2}(\text{Base})(\text{Lateral height})[/tex]

Lateral height of the triangle = [tex]\sqrt{6^2+(9.1)^2}[/tex] [By applying Pythagoras theorem]

                                                = [tex]\sqrt{82.81+36}[/tex]

                                                = [tex]\sqrt{118.81}[/tex]

                                                = 10.9 cm

Area of the lateral side = [tex]\frac{1}{2}(12)(10.9)[/tex]

                                      = 60.54 cm²

Surface area of the given pyramid = Area of the base + 4(Area of one lateral side)

                                                          = 144 + 4(60.54)

                                                          = 144 + 242.16

                                                          = 386.16 cm²

Given:

[tex]\alpha, \beta, \gamma[/tex] are three interior angles of any triangle.

To prove:

[tex]\cos (\alpha+\beta+\gamma)=-1[/tex]

Solution:

Angle sum property of a triangle: According to this theorem the sum of all three interior angle of a triangle is always 180 degrees.

It is given that, [tex]\alpha, \beta, \gamma[/tex] are three interior angles of any triangle.

By using the angle sum property of triangles, we get

[tex]\alpha+\beta+\gamma =180^\circ[/tex]              ...(i)

We need to prove,

[tex]\cos (\alpha+\beta+\gamma)=-1[/tex]

Taking LHS, we get

[tex]LHS=\cos (\alpha+\beta+\gamma)[/tex]

[tex]LHS=\cos (180^\circ)[/tex]                [Using (i)]

[tex]LHS=-1[/tex]

[tex]LHS=RHS[/tex]

Hence proved.

Decision Rule

The critical region for one tailed test with 7 d.f is t > 1.415 for

H0 : ud ≤ 0 against the claim Ha: ud > 0

Step-by-step explanation:

The data given is

Population mean = ud= 0

Sample difference mean = d`= 3.125

Sample difference standard deviation = sd= 2.911

Sample size= n= 8

Formulate the null and alternate hypotheses as

H0 : ud ≤ 0 against the claim Ha: ud>0

The significance level ∝= 0.1

The degrees of freedom = n-1 = 8-1 = 7

The critical region for one tailed test with 7 d.f is t > 1.415

The test statistic is

t= d`- ud/ sd/ √n

Putting the values

t= 3.125-0 / 2.911/√8

t= 3.125/1.0292

t= 3.036

since the calculated value of t falls in the critical region we reject the null hypothesis .

Answer:

[tex]108\frac{1}{3}[/tex] %

Step-by-step explanation:

[tex]\frac{25}{12} :\frac{y}{100}[/tex]

12 · y = 25 · 100

12y = 2500

12y ÷ 12 = 2500 ÷ 12

[tex]y=208\frac{1}{3}[/tex]

[tex]208\frac{1}{3} - 100 = 108\frac{1}{3}[/tex]

A pentagon's largest internal angle is 150 degrees.

The geometric shape known as a pentagon has five sides and five angles. Penta here means five, and gon means angle. One of the different kinds of polygons is the pentagon. A regular pentagon's internal angles add up to 540 degrees.

Given, The measures of the interior angles of a pentagon are 2x + 15, 3x, 3x + 5, 4x + 10, and 5x. Since the sum of all the interior angles of the pentagon is 540 degrees. Hence

2x + 15 + 3x + 3x + 5 + 4x + 10 + 5x = 540

17x  + 30 = 540

17x  = 510

x = 30

All five angles of the pentagon are 75, 90, 95, 130, and 150.

Therefore, the biggest interior angle of a pentagon is 150 degrees.

Answer:

a) 388.03

b) 148.49

c) π/8

Step-by-step explanation:

Find the diagram attached

Let the opposite side be y

Given

a) Hypotenuse = 420

theta = 3π/8 rad

theta = 3(180)/8

theta = 67.5degrees

Using the SOH CAH TOA identity

sin theta = opposite/hypotenuse

sin 67.5 = y/420

x = 420sin67.5

x = 420(0.9238)

x = 388.03

Hence the length of the side opposite to the given angle is 388.03

b) Hypotenuse = 420

theta = 3π/8 rad

theta = 3(180)/8

theta = 67.5degrees

Using the SOH CAH TOA identity

cos theta = adjacent/hypotenuse

cos 67.5 = x/420

x = 420cos67.5

x = 420(0.3827)

x = 148.49

Hence the length of the side adjacent to the given angle is 148.49

c) The sum of angle in the triangle is π

Let the measure of the unknown angle be z

z + 3π/8 + π/2 = π

z + 3π+4π/8 = π

z + 7π/8 = π

z = π - 7π/8

z = (8π-7π)/8

z = π/8

Hence the measure of the other acute angle is π/8
