A number decreased by 8 is 27.

Answer:

243

Step-by-step explanation:

-9^2 = -9 * -9 = 81

81 * 3 = 243

We have the next formula to calculate the volume of the cylinder

where

r is the radius

h is the height

in our problem

r=3in

h=9in

we substitute the values

the volume round to the nearest tenth is V=254.5 in ^3

The probability of that the first 40 feet in a roll contain no flaws is ≈ .3012

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Θ = μ = [tex]\frac{100 foot}{3 flaws}[/tex]

a ) We assume that the length until the first flaw follows an exponential distribution.

Probability density function of exponential distribution:

f(x) = [tex]\frac{1}{Θ} e^{\frac{-x}{Θ} } = \frac{1}{100/3}e^{-x/(100/3)} = \frac{3}{100}e^{-3x/100}[/tex]

The first 40 feet in a roll of 100 feet contain no flaws if the first flaw occurs after 40 feet.

The probability is the integral over the corresponding interval:

If one of the daughters marries a non-bald man and they have a son, the chance that the son will become bald as an adult is 0%

If the couple has a daughter, the chance that she will become bald as an adult is 0%

In the question, we have been given that the neither the father nor the mother is bald, and out of the four children only one son is bald, but the other son and the two daughters are not bald, now we solve the following:

Part a

A chance that the son will become bald as an adult:

If the daughter has no bald gene (XX), and she marries a non bald man then there is 0% chance that the son will become bald as an adult because neither the mom nor the dad has the baldness gene

Part b

The chance that she will become bald as an adult:

If the daughter having a bald gene ([tex]X^{b} X[/tex]) marries a non bald (XY)man then also there is a 0% chance that the daughter will be bald as an adult. As the baldness is a recessive trait, for the daughter to be bald she needs to have two baldness gene( one from father and one from mother). And since this is not the case the daughter might have baldness gene but the phenotype will be non-bald.

The percentage of the students that like rap are also in grades 9–10 is 32%.

Given data:

Grade 9-10 for Rap = 40

Row total for grade 9-10 = 125

Now let determine the percentage of rap in grades 9-10 using this formula

Percentage of rap in grades 9-10 = Grade 9-10 for Rap / Row total for grade 9-10

Let plug in the formula

Percentage of rap in grades 9-10 = 40 /125

Percentage of rap in grades 9-10 = 0.32 × 100

Answer:

No solution

Step-by-step explanation:

2- 3x + 4 + x = -2x + 1

2  -3x  + 4 + x = -2x + 1

6  -3x + x = -2x + 1

6  -3x + x = -2x + 1

6  -2x = -2x + 1

6  -2x = -2x + 1

move -2x to the right by adding 2x on both sides

6  -2x = -2x + 1

Answer:

D

Step-by-step explanation:

2d + 8y = 20

y = 2

substitute y = 2 into the other equation

2d + 8(2) = 20

2d + 16 = 20 ( subtract 16 from both sides )

2d = 4 ( divide both sides by 2 )

d = 2

solution is (2, 2 )

answer-> D. (2,2)

Given,

2d + 8y = 20  .............................................(Equation i)

y = 2 .............................................................(Equation ii)

substituting y = 2 in equation i, we get

2d + 8(2) = 20

2d + 16 = 20

2d = 20 - 16

2d = 4

d = 2

Hence the correct answer would be option D. (2,2)

From the question, we were told that Garcia's bike rentals cost $38 to rent bike for 9 hours.

We are to find how many hours will a customer use the bike per dollar.

This can also be likened to calculating miles per gallon.

if i can drive 300 miles on 10 gallons of gas then my miles per gallon is 300/10 = 30 mpg.

So, hours per dollar is also a division problem too.

(9 hours)/($38)

= 9/38

= 0.2368

= 0.24 hours per dollar (to the nearest hundredth)

Forming algebraic equation and solving:

Let the income  = x

Amount spent on housing = (1/3) of the income

                                             [tex]\sf = \dfrac{1}{3}x[/tex]

Amount spent of daily expenditure = (2/5) of the income

                                                          [tex]\sf =\dfrac{2}{5}x[/tex]

Income = Savings + housing expenditure + daily expenditure  

Income - housing expenditure - daily expenditure = savings

[tex]\sf x - \dfrac{1}{3}x-\dfrac{2}{5}x=24600\\\\\\\dfrac{x*15}{1*15}-\dfrac{1*5}{3*5}x-\dfrac{2*3}{5*3}x = 24600\\\\\\[/tex]

Answer:

Simplifying

7 + 2x = 4x + -3

Reorder the terms:

7 + 2x = -3 + 4x

Solving

7 + 2x = -3 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

7 + 2x + -4x = -3 + 4x + -4x

Combine like terms: 2x + -4x = -2x

7 + -2x = -3 + 4x + -4x

Combine like terms: 4x + -4x = 0

7 + -2x = -3 + 0

7 + -2x = -3

Add '-7' to each side of the equation.

7 + -7 + -2x = -3 + -7

Combine like terms: 7 + -7 = 0

0 + -2x = -3 + -7

-2x = -3 + -7

Combine like terms: -3 + -7 = -10

-2x = -10

Divide each side by '-2'.

x = 5

Simplifying

x = 5

Answer:

4x² + 29x + 7 = (4x + 1)(x + 7)

Step-by-step explanation:

Like terms are terms with same variable and same power.

       Perimeter = sum of all the sides

                         = 3x² + 1 + 15x + 6 + x² + 14x

                         = 3x² + x² + 15x + 14x + 1 + 6

Combine like terms,

                        = 4x² + 29x + 7

Factorize:

        Sum = 29

  Product = 4*7 = 28

   Factors = 1 , 28    {28 + 1 = 29 & 28*1 = 28}

Rewrite the middle term using the factors,

                           = 4x² + x + 28x + 7

                           = x(4x + 1) + 7(4x + 1)

                           = (4x + 1)(x + 7)

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The algebraic expression is,

'' An integer is subtracted from 8 times the next consecutive integer, the difference is 71.''

Now,

Let a number = x

Then, Its consecutive number = (x + 1)

So, We can formulate;

⇒ 8 (x + 1) - x = 71

Solve for x as;

⇒ 8x + 8 - x = 71

⇒ 7x + 8 = 71

⇒ 7x = 71 - 8

⇒ 7x = 63

⇒ x = 9

Thus, The value of greater number = x + 1

                                                      = 9 + 1

                                                       = 10

Therefore, The value of the greater integer will be 10.

Answer:

x=71 y=109

Step-by-step explanation:

The rules of the patterns are 3 + 3x and 6 + 6y

The patterns are given as:

For pattern x, we have the following highlights:

Start = 3

Rule = Add 3

This means that the nth term of pattern x is:

Pattern x = 3 + 3x

For pattern y, we have the following highlights:

Start = 6

Rule = Add 6

This means that the nth term of pattern y is:

Pattern y = 6 + 6y

For pattern x, set x = 0, 1, 2 and 3

So, we have

3 + 3x = 3 + 3(0) = 3

3 + 3x = 3 + 3(1) = 6

3 + 3x = 3 + 3(2) = 9

3 + 3x = 3 + 3(3) = 12

For pattern y, set y = 0, 1, 2 and 3

So, we have

6 + 6x = 6 + 6(0) = 6

6 + 6x = 6 + 6(1) = 12

6 + 6x = 6 + 6(2) = 18

6 + 6x = 6 + 6(3) = 24
