Look at the graph and choose the correct answer.

Answer:

d. The histogram would be approximately bell-shaped, and the normal quantile plot would have data points have follow a straight-line pattern.

Step-by-step explanation:

Since the variable is normally distributed, the histogram of women's height should be approximately bell shaped (if the data was obtained form a random sample).

Again, the variable is normally distributed, therefore, the quantile plot should follow a straight line pattern (a diagonal line to be more precise).

Answer:

288 Miles

Step-by-step explanation:

Solve for x (speed)

5.5x = 264

Divide by 5.5

x = 48

y = 48x

Subsitute 6 hours in for x

y = 48(6)

y = 288

Answer: Allie went 288 miles in 6 hours.

Step-by-step explanation:

First, you must find out how many miles Allie travled in one hour

= 264/5.5

= 48

Next, multiply the quotient by the number of hours to get the answer.

= 48 x 6

= 288

Answer:

Answer:

80%

Step-by-step explanation:

To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.

part = 48

whole = 60

percent = part/whole * 100%

percent = 48/60 * 100%

percent = 80%

Answer: 80%

x = 33°

Then :-

m∠1 = 33° ( angle x and angle 1 are corresponding angles on a transversal )

m∠1 + m∠2 = 90° ( angle 1 and angle 2 are complementary angles )

33 + ∠2 = 90

∠2 = 90 - 33

m∠2 = 57°

m∠1 + m∠3 = 180° ( angle 1 and angle 3 are a linear pair )

Step-by-step explanation:

Answer: a = -2, b = -2, c = 1.

Step-by-step explanation:

We know that:

y = a*x^2 + b*x + c.

Then:

y' = 2*a*x + b

y'' = 2*a.

Then we can write the equation:

y′′ + y′ − 2y = 4x^2.

as:

2*a + 2*a*x + b - 2*(a*x^2 + b*x + c) = 4*x^2

To solve this, the first step is moving all the terms to the same side:

2*a + 2*a*x + b - 2*a*x^2 - 2*b*x - 2*c - 4*x^2 = 0

Now let's group terms with the same power of x.

(-4 - 2*a)*x^2 + (-2*b + 2*a)*x + (-2c + b) = 0

Now, this must be zero for all the values of x, then the parenthesis must be equal to zero:

-4 - 2*a = 0

-2*b + 2*a = 0

-2*c + b = 0

From the first equation:

-4 - 2*a = 0

-4 = 2*a

-4/2 = a

a = -2

And from the second equation:

-2*b + 2*a = 0

2*a = 2*b

a = b

b = -2.

From the third equation we have:

-2c + b = 0

-2c = b

c = b/-2 = -2/-2 = 1.

c = 1

Then our equation is:

y = -2*x^2 - 2*x + 1.

Answer:

x<10

Step-by-step explanation:

i think this is the answer

x<10 is the solution of the inequality  2x-8 <12

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is 2x-8<12

Two times of x minus eight less than twelve

x is the variable

We have to find the solution of the inequality

2x<20

Divide both sides by 2

x<10

Hence, x<10 is the solution of the inequality  2x-8 <12

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

L is the length of the rectangle:

W is the width of the rectangle.

Given

Perimeter = 214feet

If the length is 41 ft longer than the width, then L = 41+W

Substitute L = 41+W into the formula:

P = 2(L+W)

214 = 2(41+W+W)

214 = 2(41+2W)

214 = 82+4W

4W = 214-82

4W = 132

W = 132/4

W = 33 feet

Since L = 41+W

L = 41+33

L = 74 feet

Hence the dimension of the field is 74ft by 33ft

The width of the playing field is 33feet

Quantity of flour needed to make 20 pancakes =

[tex] = \frac{3 \times 1 + 2}{3} [/tex]

[tex] = \frac{5}{3} \: cups \: of \: flour[/tex]

Then , number of pancakes that can be made from 1 cup of floor :-

[tex]20 \div \frac{5}{3} [/tex]

[tex]20 \times \frac{3}{5} [/tex]

[tex] \frac{60}{5} [/tex]

[tex] = 12 \: pancakes[/tex] .

Therefore , 12 pancakes can be made from 1 cup of floor .

Number of pancakes that can be made with 1 cup of flour = 12 pancakes

Number of pancakes that can be made with 9 cups of flour :-

= 9 × 12

= 108 pancakes

Therefore , I can make 108 pancakes with 9 cups of flour .

Yes , I have enough flour to make 100 pancakes . I say this because :-

With one cup of flour I can make = 12 pancakes

With 9 cups of flour I can make =

As I can make 108 pancakes with 9 cups of flour , I can conclude that I have enough flour to make 100 pancakes .

Answer:

The number of standard deviation above the mean is  [tex]  z_o   = 1.4607 [/tex]

Step-by-step explanation:

From the question we are told that

   The mean weight of  ears of  corn from each farm is  [tex]\mu=1.26[/tex]

   The standard deviation of ears of corn from Iowa is [tex]\sigma_1[/tex]

   The standard deviation of ears of corn from Ohio is

       [tex] \sigma_2= 0.01 + \sigma_1 [/tex]

  The weight of a random selected ear of corn from Iowa is  x =  1.39 pound

  The standardized score is  z =1.645

   The weight of a random selected ear of corn from Ohio is  [tex]x_1 =  1.39\ pound[/tex]

Generally the standardized score of weight of corn from Iowa is mathematically  represented as

        [tex]z  =  \frac{ 1.39 -  1.26 }{\sigma_1 }[/tex]

=>     [tex] 1.645 =  \frac{ 1.39 -  1.26 }{\sigma_1 }[/tex]  

=>      [tex]  \sigma_1 =  \frac{ 1.39 -  1.26 }{ 1.64 5}[/tex]  

=>      [tex]  \sigma_1  =   0.0790 [/tex]  

Generally the standardized score of weight of corn from Ohio is mathematically  represented as

         [tex]z_o  =  \frac{ 1.39 -  1.26 }{\sigma_2 }[/tex]

=>     [tex] z_o=  \frac{ 1.39 -  1.26 }{0.01 + \sigma_1 }[/tex]  

=>      [tex]  z_o =  \frac{ 1.39 -  1.26 }{  0.089}[/tex]  

=>      [tex]  z_o   = 1.4607 [/tex]

Because the value is positive it means that this value represent the number of standard deviation above the mean.

Using the normal distribution, it is found that the weight with respect to the Ohio distribution is 1.46 standard deviations from the mean.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For the Iowa farm:

Then, the standard deviation can be found as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.645 = \frac{1.39 - 1.26}{\sigma}[/tex]

[tex]1.645\sigma = 0.13[/tex]

[tex]\sigma = \frac{0.13}{1.645}[/tex]

[tex]\sigma = 0.079[/tex]

In Ohio:

Hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1.39 - 1.26}{0.089}[/tex]

[tex]Z = 1.46[/tex]

The weight with respect to the Ohio distribution is 1.46 standard deviations from the mean.
