Step-by-step explanation:

The product for this expression is 1.5 multiplied by itself 4 times. This means you raise it to the fourth power, thus giving you 3/2^4 or 1.5^4.

Answer:

1.2 liters

Step-by-step explanation:

1 bucket has a volume of 80 cL.

15 buckets have a volume of 15 * 80 cL = 120 cL

1 L = 100 cL

120 cL * (1 L)/(100 cL) = 1.2 L

Answer:

The  decision is to fail to reject the null hypothesis

This  means that  the population mean apartment rental rate now does not exceeds the level reported in 2002

Step-by-step explanation:

From the question we are told that

   The population mean is  [tex]\mu = \$895[/tex]

   The  population standard deviation is  [tex]\sigma = \$225[/tex]

   The sample  size is  [tex]n = 180[/tex]

   The sample mean is  [tex]\= x = \$ 915[/tex]

    The sample standard deviation is [tex]s = \$ 227.50[/tex]

   The  level of significance is [tex]\alpha = 0.01[/tex]

The null hypothesis is  [tex]H_o : \mu \le \$ 895[/tex]

The  alternative hypothesis is  [tex]H_a : \mu > \$895[/tex]

   The test statistics is evaluated as

           [tex]t = \frac{\= x- \mu}{\frac{\sigma }{\sqrt{n} } }[/tex]

=>       [tex]t = \frac{ 915 - 895}{ \frac{225}{ \sqrt{180} } }[/tex]

=>       [tex]t =1.193[/tex]

So from  z-table  the p-value is obtained, the value is  

      [tex]p-value = P(Z > t) = P(Z > 1.193 ) = 0.11643[/tex]

So From the value obtained we see that

       [tex]p-value > \alpha[/tex] so  we  fail to reject the null hypothesis

= 0.03170979

This question is Incomplete because it lacks the diagram of the box plot. Please find attached the diagram of the box plot

Answer:

B) 102 ounces

Step-by-step explanation:

Looking at the attached diagram, we can see the box plot it divided into different segment

The median weight of the babies = 110 ounces

The maximum weight of the babies is between = 140 and 130, approximately let's say 135 ounces

The minimum weight is 80 ounces

Then the box in the middle is divided into 3

It has the First Quartile

Median

And third Quartile

Since we have 160 infants born in the local hospital, about 40 of the birthweights we fall into

= 40/160 = 1/4

1/4 represents the first Quartile

Looking at the box plot, 40 of the birthweights were below 102 ounces.

Answer:

Length= 44 feet

Width= 18 feet

Step-by-step explanation:

Let the length= x

Let the width = y

Length is 8 feet longer than 2 times the

width.

X= 8+2y

The perimeter of his classroom floor is 124 feet

Perimeter= 2(x+y)

124= 2x+2y

But x= 8+2y

124= 2x+2y

124= 2(8+2y) +2y

124= 16 +4y +2y

124-16= 6y

108= 6y

18 = y

Width= 18 feet

X= 8+2y

X= 8 +2(18)

X= 8+36

X= 44

Length= 44 feet

Answer: f(-9)=137

Step-by-step explanation:

To find f(-9), you plug in -9 into x.

f(-9)=2(-9)²+5(-9)+20                           [solve parenthesis]

f(-9)=2(81)-45+20                                 [multiply]

f(-9)=162-45+20                                   [subtract]

f(-9)=117+20                                          [add]

f(-9)=137

Answer:

The correct answer to this would be D, adjacent angles share a side.

Step-by-step explanation:

Adjacent angles share a common side as well as a common vertex.

I hope this helps :)

The statement that best describes adjacent angles is that adjacent angles share a side.

A vertex is where two non parallel lines meet.For example a triangle has 3 vertex.We can also say that vertex is a point where two non parallel lines meet to form an angle.

According to the given question the best description of adjacent angle is that they share a side.

We can say that adjacent angles are those angles which are placed next to each other.

Adjacent angle also share a common vertex but they do not overlap each other.

Answer:

Step-by-step explanation:

[tex]5(x + 3) + x = 4(x + 3) + 3 \\ 5x + 15 + x = 4x + 12 + 3 \\ 5x + x - 4x = 12 + 3 - 15 \\ 2x = 0[/tex]

Divide both sides of the equation by 2

2x/2 = 0/2

x = 0

(4+612+x)=2(3x+8)

4+612+x=6x+16

4+612-16=6x-x

600=5x

Divide both sides of the equation by 5

600/5 = 5x

Answer:

50/b in

Step-by-step explanation:

Use the area formula A = (1/2)(base)(height).

Here the area A is given and is 25 in^2; the base is not given, so use 'b.'

Then, since A = (1/2)(base)(height),

(height) = 2A/(base) = 2(25 in^2)/b = 50/b in

Answer:

V  = 36Π cubic Centimetres

Step-by-step explanation:

Step(i):-

Volume of the solid

The Volume of the solid formed by revolving the region bounded by the curve y = f(x) and rotated around  the x-axis defined by

                [tex]V = \pi \int\limits^a_b {[f(x)]^{2} } \, d x[/tex]

Step(ii):-

Given two curves are y = x²  and y = 9

The point of intersection of two curves

                                y = x²...(i)

                        and y = 9 ...(ii)

Equating both equations , we get

                       x² - 9 =0

                 ⇒  x² - 3² =0

                 ⇒ (x+3)(x-3) =0

                 ⇒ x+3=0  and x-3=0

                 x = 3 ⇒ y = 9

                x = -3 ⇒y = 9

The point of intersection ( -3,9) and (3,9)

Step(iii):-

                 [tex]V = \pi \int\limits^a_b {[(f(x)]^{2} } \, -[g(x)]^{2})d x[/tex]

The limits x- varies from -3 to 3

                   [tex]V =\pi (\int\limits^3_3 {x^{2} } \, dx +\int\limits^3_3{9} \, dx[/tex]

                   [tex]V =\pi (\frac{x^{3} }{3} -9 x)^{3} _{-3}[/tex]

                 [tex]V= \pi ( \frac{27}{3} - 9(3) - (\frac{-27}{3} -9(-3))[/tex]

                V = π ( |-36| = 36Π cubic Centimetres

Answer: B. The exact frequency for each category on the scale of measurement

Step-by-step explanation: The main difference between a grouped table and regular frequency distribution exists in the fact that ; grouped table takes in a defined range of (X) values, that is takes more than one individual value per group and takes the frequency of all scores or values in the group, hence giving the frequency of the scores in the interval rather than the frequency of each individual score. On the other hand, the regular frequency distribution treats values or scores individually and then takes the frequency of each score. This way a regular frequency distribution enables us to know the exact number or distribution of each individual score.

The information in a regular frequency distribution table that is not available from a grouped table is (b) the exact frequency for each category on the scale of measurement

There are several similarities between a regular frequency table, and a grouped frequency table.

However, both frequency tables have a major difference.

This difference is in the frequency of the data they represent

While a regular frequency table shows the exact frequency of each data element, a grouped frequency table cannot show the exact frequency of each data element.

Hence, the true option is (b)

Complete Question

The complete question is shown on the first uploaded image

Answer:

The solution is  [tex]\frac{\delta  (x,y)}{\delta (u, v)} | = 10e^{-4u}[/tex]

Step-by-step explanation:

From the question we are told that

        [tex]x =  e^{-2a} cos (5v)[/tex]

and  [tex]y  =  e^{-2a} sin(5v)[/tex]

Generally the absolute value of the determinant of the Jacobian for this change of coordinates is mathematically evaluated as

     [tex]| \frac{\delta  (x,y)}{\delta (u, v)} | =  | \ det \left[\begin{array}{ccc}{\frac{\delta x}{\delta u} }&{\frac{\delta x}{\delta v} }\\\frac{\delta y}{\delta u}&\frac{\delta y}{\delta v}\end{array}\right] |[/tex]

        [tex]= |\ det\ \left[\begin{array}{ccc}{-2e^{-2u} cos(5v)}&{-5e^{-2u} sin(5v)}\\{-2e^{-2u} sin(5v)}&{-2e^{-2u} cos(5v)}\end{array}\right]  |[/tex]

[tex]Let \   a =  -2e^{-2u} cos(5v),  \\ b=-2e^{-2u} sin(5v),\\c =-2e^{-2u} sin(5v),\\d=-2e^{-2u} cos(5v)[/tex]

So

     [tex]\frac{\delta  (x,y)}{\delta (u, v)} | = |det  \left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right] |[/tex]

=>    [tex]\frac{\delta  (x,y)}{\delta (u, v)} | = | a *  b  - c* d |[/tex]

substituting for a, b, c,d

=>    [tex]\frac{\delta  (x,y)}{\delta (u, v)} | =  | -10 (e^{-2u})^2 cos^2 (5v) - 10 e^{-4u} sin^2(5v)|[/tex]

=>   [tex]\frac{\delta  (x,y)}{\delta (u, v)} | =  | -10 e^{-4u} (cos^2 (5v)   + sin^2 (5v))|[/tex]

=>  [tex]\frac{\delta  (x,y)}{\delta (u, v)} | = 10e^{-4u}[/tex]
