Volume of a pyramid = lwh /3 ==12/3==4

Answer:

According to theorem 7.5

Π ABB'A' ≅ Π DEE'D'  

therefore by transitivity of equivalence  it is proven that triangle ABC and triangle DEF are triangles with equal defects and a pair of congruent sides

Step-by-step explanation:

To prove that triangle ABC and triangle DEF are triangles with equal defects and a pair of congruent sides :

Assume:  б(Δ ABC ) =  б(Δ DEF ) and also AB ≅ DE

let Π ABB'A' and DEE'D' be taken as the saccheri quadrilaterals that corresponds to Δ ABC and Δ DEF  respectively

Following the Lemma above; б(Π ABB'A' ) = б( Π DEE'D' ) given that

AB = summit of ABB'A' and DE = summit of DEE'D'  also  AB ≅ DE

According to theorem 7.5

Π ABB'A' ≅ Π DEE'D'  

therefore by transitivity of equivalence  it is proven that triangle ABC and triangle DEF are triangles with equal defects and a pair of congruent sides

Use the shell method. The volume is

V = 2π ∫₅⁸ (x - 5) x ² dx

V = 2π ∫₅⁸ (x ³ - 5x ²) dx

V = 2π (1/4 x ⁴ - 5/3 x ³) |₅⁸

V = π/6 (3x ⁴ - 20x ³) |₅⁸

V = π/6 ((3 × 8⁴ - 20 × 8³) - (3 × 5⁴ - 20 × 5³))

V = 891π/2

Answer:

A) Alexis is x-5 years old

B) Thomas is 3x years old

C) Thomas is 24 years older than Jenny (3×12=36 ; 36-12)

Alexis's age is x - 5.

Thomas's age is 3x.

Thomas is 24 years older than Jenny.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

A)

Jenny = x years old

Alexis = 5 years younger than Jenny.

So,

Alexis's age in terms of x.

Alexis's age

= Jenny's age - 5

= x - 5

B)

Thomas = 3 times as old as Jenny.

Thomas's age in terms of x.

Thomas's age = 3x

C)

x = 12,

Jenny = 12 years old.

Alexis = 5 years younger than Jenny,

So,

Alexis's age

= Jenny's age - 5

= 12 - 5

= 7

Now,

Thomas = 3 times as old as Jenny.

And,

Jenny = 12 years old.

Thomas's age

= 3x

= 3 x 12

= 36

Now,

Thomas's age - Jenny's age

= 36 - 12

= 24

Therefore,

Alexis's age = x - 5.

Thomas's age = 3x

Thomas is 24 years older than Jenny.

Answer:

The surface area is 98 square feet.

Step-by-step explanation:

7 x 4 = 28

28 x 3 = 84

4 x 3.5 = 14

14 / 2 = 7

7 x 2 = 14

84 + 14 = 98

s = 4

h = 3

C = ?

C = s(3h + 5)

C = 4(3·3 + 5)

C = 4(9 + 5)

Answer:

0.000005178

Step-by-step explanation:

we test for the goodness of fit

h0; drink preferences not changed

h1: drink preferences changed

alpha = 0.05

we solve for the test statistics

the chsquare test was performed in the attachment

Chi square = (O-E)²/E

chisquare = 32.30188

degree of freedom = n -1 = 6-1 = 5

using the chi distribution function on excel i calculated the p value

CHIDIST(32.30188, 5) =

P-value = 0.000005178

pvalue is less than 0.05 so we reject null hypothesis and conclude that there is sufficient evidence that drink preferences are changed.

Step-by-step explanation:

[tex]A[/tex] denotes some event, [tex]\overline{A}[/tex] denotes the complement of [tex]A[/tex] that is [tex]\overline{A}[/tex]contains all the events that do not occur in A.

And, the value of [tex]P(\overline{A})[/tex] is,  [tex]P(\overline{A}) = 0.994[/tex]

Used the concept of probability which states that,

[tex]P (A) + P(\overline{A}) = 1[/tex]

Where, [tex]A[/tex] and [tex]\overline{A}[/tex] are events.

When [tex]A[/tex] denotes some event, [tex]\overline{A}[/tex] denotes the complement of [tex]A[/tex] that is [tex]\overline{A}[/tex]contains all the events that do not occur in A.

Given that:

P(A) = 0.006

We used the formula of probability which stated that,

[tex]P (A) + P(\overline{A}) = 1[/tex]

Where, [tex]A[/tex] and [tex]\overline{A}[/tex] are events.

Substitute [tex]P (A) = 0.006[/tex] into the above formula,

[tex]0.006 + P(\overline{A}) = 1[/tex]

Subtract 0.006 on both sides,

[tex]P(\overline{A}) = 1 - 0.006[/tex]

Therefore, the value of [tex]P(\overline{A})[/tex] is,

[tex]P(\overline{A}) = 0.994[/tex]

So, If [tex]A[/tex] denotes some event, [tex]\overline{A}[/tex] denotes the complement of [tex]A[/tex].

And, [tex]P(\overline{A}) = 0.994[/tex]
