Answer:

Choose the formula for the volume of a cone V = mrh written in terms of h.

We are given that ∠BDA is bisected

this means that ∠BDC = ∠ADC

Finding x :

Since ∠BDC = ∠ADC:

7x - 19 = 9x - 37

2x = 18

x = 9

Finding ∠ADC:

We are given that ∠ADC = 9x - 37

now that we know that x = 9, replacing x:

∠ADC = 9(9)-  37

∠ADC = 44°

Answer:

The decision rule is  

Fail to reject the null hypothesis

The conclusion is  

There is no sufficient evidence to show that  the proportion of all children in the United States who currently live with at least one grandparent is higher than 11%

Step-by-step explanation:

From the question we are told that

   The population proportion is [tex]p = 0.11[/tex]

   The sample size is  n =  1640

   The number found to be living with at least one grandparent is [tex]k = 225[/tex]

   The level of significance is  [tex]\alpha = 0.02[/tex]

   The null hypothesis is [tex]H_o : p = 0.11[/tex]

   The alternative hypothesis is  [tex]H_a : p > 0.11[/tex]

Generally the sample proportion is mathematically represented as

     [tex]\^ p = \frac{ k }{n}[/tex]

=>  [tex]\^ p = \frac{ 225 }{1640 }[/tex]

=>  [tex]\^ p = 0.1372[/tex]

Generally the test statistics is mathematically represented as

     [tex]z= \frac{\^ p - p }{ \sqrt{\frac{p(1- p)}{n} } }[/tex]

=>[tex]z = \frac{ 0.1372 - 0.11 }{ \sqrt{\frac{0.11(1- 0.11)}{1640} } }[/tex]

=>[tex]z = 0.0077[/tex]

From the z table  the area under the normal curve to the left corresponding to  0.0077  is  

    [tex]p-value = P(Z > 0.0077) = 0.4969[/tex]

From the value obtained we see that [tex]p-value > \alpha[/tex] hence

The decision rule is  

Reject the null hypothesis

The conclusion is  

 There is no sufficient evidence to show that  the proportion of all children in the United States who currently live with at least one grandparent is higher than 11%

nd good luck w thiss

Answer:

Decimal: .33

Percent: 33%

Step-by-step explanation:

To get the decimal, you divide the top number by the bottom number. So you divide 1 by 3, which equals .33

To get the percentage, you move the deciaml back twice.

.33 -> 3.3 -> 33.=33%

Given:

A baseball player get a hit in 31% of his at-bats.

To find:

The probability that he will  get a hit 5 at-bats in a row.

Solution:

Since, a baseball player get a hit in 31% of his at-bats, therefore

Probability that he get a hit = [tex]\dfrac{31}{100}[/tex]

                                           = [tex]0.31[/tex]

Now, the probability that he will  get a hit 5 at-bats in a row is

[tex]P=0.31\times 0.31\times 0.31\times 0.31\times 0.31[/tex]

[tex]P=(0.31)^5[/tex]

[tex]P=0.0028629151 [/tex]

Therefore, the required probability is [tex](0.31)^5[/tex] and it can be written as 0.0028629151 .

Answer:

Step-by-step explanation:

A graph can be helpful. It can show the locations of the maximum and minimum.

__

The maximum is found at the vertex of the parabola, located where ...

  x = -b/(2a)

  x = -1.42/(2(-0.015)) = 47 1/3

The value M(47 1/3) is ...

  M(47 1/3) = (-0.015(47 1/3) +1.42)(47 1/3) -7.8 = 0.71(47 1/3) -7.8 = 25 121/150

The maximum gas mileage is 25 121/150 ≈ 25.8067 mpg at 47 1/3 mph.

__

The minimum will be at one end or the other of the interval. Here, the maximum is farther from the lower end of the domain, so we expect to find the minimum there:

  M(30) = (-0.015(30) +1.42)(30) -7.8 = 0.97(30) -7.8 = 21.3

The absolute minimum gas mileage is 21.3 mpg at 30 mph.

Answer:

  83.73 in³

Step-by-step explanation:

It is appropriate to use the formula for the volume of a cone:

  V = (1/3)πr²h

  V = (1/3)(3.14)(4 in)²(5 in) ≈ 83.73 in³

The volume of the cone is about 83.73 in³.

9514 1404 393

Answer:

Step-by-step explanation:

Adding the same number to both sides of the equation is an acceptable move. The addition property of equality tells Grace that the value of the variable will remain unchanged by such a move.

Her new equation would be ...

  2x +20 +10 = 15 +10

  2x +30 = 25 . . . . the result of Grace's move

_____

Additional comment

There may be very good reasons why Grace would want to do that. If solving the equation is Grace's intent, that move would be counterproductive. For the purpose of solving the equation, it would be more productive to either subtract 20 from both sides, or divide both sides by 2. These steps would give, respectively, ...

  2x = -5

  x +10 = 7.5
