Answer:

43 ; 0.88493

Step-by-step explanation:

Using the Zscore formula :

Zscore = (x - m) / s

m = mean ; s = standard deviation

Profit = $1.5 - $1.2 = $0.3

Loss = $1.2 - $1 = 0.2

Cummlative probability :

Profit / (profit + loss)

0.3 / (0.3 + 0.2) = 0.3 / 0.5 = 0.6

To obtain the x, at Z at 0.6 = 0.26

m = 40 ; s= 10

Hence,

0.26 = (x - 40) / 10

0.26 * 10 = x - 40

2.6 = x - 40

2.6 + 40 = x

x = 42.6 `; 43 approximately

x = 52

P(x < 52) :

Zscore = (52 - 40) / 10

P(Z < 1.2)

Answer:

a) $654

b) 27 unidades cuadradas

c) 721

Step-by-step explanation:

a) ¿Cuál es el valor de un bolígrafo cuando la docena se compra por $ 7848?

Una docena = 12

Por eso:

12 bolígrafos = $ 7848

1 bolígrafo = $ x

Cruz multiplicar

12 bolígrafos × $ x = 1 bolígrafo × $ 7848

$ x = 1 bolígrafo × $ 7848/12

$ x = $654

b) Área de un triángulo ¿9 unidades de base y 6 unidades de altura?

c) Cien veces la suma de 4.5 con 2.71

Esto se calcula como:

100 × (4,5 + 2,71)

= 100 × (7.21)

= 721

Answer:

D

Step-by-step explanation:

A.

y= 6x³

to find the inverse substitute x for y and y for x and solve for y

x= 6y³ ; divide both sides by 6

x/6 =y³ ; cube root both sides

(∛x)/ ∛6 = y

so  (∛x)/6  and 6x³ are NOT inverse of each other

B

y= (x+2)/5

x= (y+2)/5; multiply by 5

5x = y+2; subtract 2

y= 5x-2 NOT corect

C

y = 5x-6

x= 5y-6; add 6 to both sides

x+6 = 5y ; divided by 5 both sides

y = (x+6)/5 is NOT correct

D

y=7x -2

x= 7y-2

x+2 = 7y , (x+2) /7 = y so  IS correct

Answer:

C. d(t) = 2.37t; 14.22 ft

Step-by-step explanation:

2.37 per minute is multiplication so A and B are definitely wrong

Another way to check is 2.37*6=14.22 so the answer is C

Answer:

D. d(t) = 6t; 14.22 ft

Step-by-step explanation:

d(t)= 2.37t; 14.22 ft

d(t)= 2.37t; 14.22 ft

Answer:

a. f(t)=2.37t

b.  14.22 feet

Step-by-step explanation:

We are given that:

A snail travels at a rate of 2.37 feet per minute.

a. write a rule to describe a function.

Let t describe the time and f(t) be a function how far snail travels

then,     f(t)=2.37×t

where the unit of t is in minutes and that of f(t) is feet

b. how far will the snail travel in 6 minutes

we have to find f(t) at t=6

f(6)= 2.37×6

  = 14.22 feet

Hence, snail traveled 14.22 feet in 6 minutes

2.37/minute

14.22 feet in six minutes

Answer:

Rule for Distance is f(t) = 2.37t and distance covered in 6 minutes is 14.22 feet.

Step-by-step explanation:

Speed of Snail = 2.37 feet per minute

To write the rule we use relation of Speed, Distance and time

Distance = Speed × Time

So, Distance cover by snail in t minutes is given by f(t) = 2.37 × t

⇒ f(t) = 2.37t

Distance traveled by Snail in 6 minutes , f(6) = 2.37 × 6 = 14.22 feet

Therefore, Rule for Distance is f(t) = 2.37t and distance covered in 6 minutes is 14.22 feet.

Answer:

103 ft^2

Step-by-step explanation:

Long sides: 2(8*4) = 64 ft^2

Under side: 3*8 = 24 ft^2

Triangles: (2(3*5))/2 = 15 ft^2

64+24+15 = 103

Answer:

103

Step-by-step explanation:

the base = 3x8 = 24

the sides are= 4 x 8 = 32

two sides = 64

triangle = 5x 3 x1/2 = 7.5

7.5 x 2 = 15

total = 103

Answer:

The number from the equation is less than 11

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be = x

Now , the equation is

Sum of a number and 3 more than twice the number is less than 36

Let us assume the sum of the numbers is 36

So ,

x + 3 more than twice the number = 36

And ,

x + ( 3 + 2x ) = 36

On simplifying the equation , we get

3x + 3 = 36

Subtracting 3 on both sides , we get

3x = 33

Divide by 3 on both sides , we get

x = 11

But , the inequality equation is less than 36

So , x < 11

Therefore , the number is less than 11

Hence , the number from the equation is less than 11

Answer:

147 cubic meters

Step-by-step explanation:

Volume = length x width x height

V = 3 x 7 x 7

V = 21 x 7

V = 147 cubic meters

It's C.

Basically, when youre dividing something, the bases would stay the same but the exponents would change. For division, you'd have to substract the exponent of the denominator from the denominator (of like bases, of course)

In this case, it's 10^8-(-3).

The only reason it's not 10⁵ is because of the negative 3. If it were a positive 3, it would become 10⁵.

Substitute 'u =14 , a= 8 and t=4

             [tex]s = 14 (4) + \frac{1}{2} 8(4)^{2}[/tex]

Answer:

72 degrees for each exterior angle and 360 degrees for all of them summed.

Step-by-step explanation:

An exterior angle of a polygon is the angle between the line extending one of its sides and the next side.  As you go around a regular n sided polygon doing this, you will rotate through a complete circle of 360 degrees.  All these angles are equal, so each one is 360/n.

For the pentagon, n=5, so the sum of all its exterior angles is 360 degrees and each exterior angle is 360/5=72 degrees.
