Step-by-step explanation:

In the pattern, there are some similarities with the first three circles.

1. The number is on the blue half.

2. The halves switch spots, red-blue, blue-red, red-blue.

So, the next one should have the number on the blue half and the next pattern should be red-blue, blue-red, red-blue, and blue-red.

Answer: 0.49

Step-by-step explanation:

given data:

no of computer services firms =200

no of firms under $1million = 102

no of firms between $1million to $20million = 61

no of firms $20million and above = 37

solution:

probability that a firm selected has 1$million or above.

P ( x ≥ $1million )

= 61/200 + 37/200

= 49/100

= 0.49

the probability of selecting with $1million or more in income taxes is 0.49%

Answer:

3876

Step-by-step explanation:

Given the following :

Fraternity members = 20

They are to attend 5 different parties in groups of 4

Meaning a group = 4 persons

Atleast one brother will attend exactly one of the parties. (the brothers are indistinguishable).

Then, exactly one brother at a party (20 - 1) = 19, since they are indistinguishable.

Group members are in 4's

19C4

From: nCr = n! /(n-r)! r!

19C4 = 19! / (19 - 4)! 4!

= 19! / 15! 4!

= (19 * 18 * 17 * 16) / (4 * 3 * 2)

= 93024 / 24

= 3876

             or:  write as:  " 2 [tex]\frac{5}{6}[/tex] " .  

___________________________

Step-by-step explanation:

___________________________

Set up a ratio:

Note:  Segment FH =  (x + 35)

         Segment JL = 20 ;

         Segment FH ~ Segment JL ;

___________________________

Note:  Segment GH = (x - 4) ;

         Segment  KL  =  5 ;

         Segment GH ~ Segment KL .

___________________________

So, ( x + 3.5) : 20 :: (x-4) : 5 ;

Write this ratio in fraction format:

___________________________

→  [tex]\frac{(x+3.5) }{20 } = \frac{(x-4) }{5}[/tex]  ;

Now; "cross-factor multiply" :

→  [tex]\frac{a}{b} = \frac{c}{d }[/tex]  ;  → [tex]ad = bc[/tex] ; { [tex]{ a\neq0 ; b\neq0 ; c\neq0 ; d\neq0[/tex] .}.

___________________________

So:

  5(x + 3.5)  =  20(x - 4) ;  

___________________________

→ To simplify, start by divide each side of the equation by "5" ;

___________________________

  →   {5(x + 3.5) } / 5  =  { 20(x - 4)  } / 5 ;

to get:

      →  (x + 3.5)  =  4(x - 4) ;

___________________________

Now, on the right-hand side of the equation;

  let us expand the expression;

___________________________

We have the expression:  " 4(x - 4) " ;

 To expand:

Note the "distributive property of multiplication:

     →   a(b + c)  = ab + ac ;

Likewise:

     →   4(x - 4)  = 4x  - 16 ;

___________________________

Now, we can rewrite our equation:

___________________________

     →   " x + 3.5  =  4x - 15 "  ;

Now, we can subtract "x" from each side of the question;

     & add "15" to each side of the equation; as folllows:

___________________________

     →     x + 3.5  =  4x - 15 ;

          - x + 15   =  - x  +15

___________________________

to get:        8.5  =  3x ;  

                   ↔  3x  = 8.5 ;

Now, divide each side of the equation by "3" ;

       to isolate "x" on one side of the equation;

       & to solve for "x" ;  as follows:

                     →  3x / 3 = 8.5 / 3 ;

             to get:   x  = 8.5 /3  

                              = 2.83333333333 ;  

                         or; write as:  " 2 [tex]\frac{5}{6}[/tex] ."

Figure number four in the image shows △MNP reflected over the y-axis to form △M`N`P`. The correct option is D.

The reflection operator geometrically repositions image elements, or pixel values, in such a way that they are reflected about a user-specified image axis or image point and placed in a new position in a matching output image.

In the given image option fourth is showing the correct reflection of the triangle △MNP over the y-axis to the form △M`N`P'.

It is observed that every point of the triangle MNP is at the same distance from the y-axis as every point of the triangle M'N'P'.

Therefore, figure number four in the image shows △MNP reflected over the y-axis to form △M`N`P`. The correct option is D.

Answer:

16 miles long to work it would be 0 miles shorter

Step-by-step explanation:

8+8 is 16

if the road was just one street it would still be the same distance

I hope this helps. THIS MIGHT BE WRONG though if someone say something else, take a good look at their answer too because the way I did it, seems like it's a little too simple.

Answer:   The distance will be about 11 miles . 2) The man's one way-trip will be 5 miles shorter.

Step-by-step explanation:

If the man  drove east by 8 miles and  North by 8 miles and we want to determine the distance that is directly  from east to north then we will use the Pythagorean Theorem  solve for that distance.

Now since we are solving for the distance directly from his home to work we will be looking for the hypotenuse in this case.

a^2 + b^2 =c^2  where c is the hypotenuse

8^2 + 8^2 =c^2

64 +64 = c^2  

c= [tex]\sqrt{128}[/tex]  

c =  11.31

  In this case the distance from his home directly to his work will be about 11 miles.

2.   To find out how much shorter the man will travel ,add the east and north distance and subtract 11.31 from it.

8 + 8 = 16

16  - 11.31 = 4.69

Answer:

The box should have base 16ft by 16ft and height 8ft Therefore,dimensions are 16 ft by 16 ft by 8 ft

Step-by-step explanation:

We were given the volume of the tank as, 2048 cubic feet.

Form minimum weight, the surface area must be minimum.

Let the height be h and the lengths be x

the volume will be: V=x²h then substitute the value of volume, we have

2048=hx²

hence

h=2048/x²

Since the amount of material used is directly proportional to the surface area, then the material needs to be minimized by minimizing the surface area.

The surface area of the box described is

A=x²+4xh

Then substitute h into the Area equation we have

A= x² + 4x(2048/x²)

A= x² + 8192/x

We want to minimize

A

dA/dx = -8192/x² + 2 x= 0 for max or min

when dA/dx=0

dA/dx= 2x-8192/x²=0

2x=8192/x²

Hence

2x³=8192

x³=4096

x=₃√(4096)

X=16ft

Then h=2048/x²

h=2048/16²

h=8ft

The box should have base 16ft by 16ft and height 8ft

Hence the dimensions are 16 ft by 16 ft by 8 ft

Answer: A. The price of the soap increases by $0.20, on average, when the thickness increases by 1 cm

Step-by-step explanation:

Given the following :

Regression equation : ŷ = 0.4 + 0.2x

Price is the response variable (ŷ)

Thickness is the explanatory variable (x)

Relating the equation given to the regression model:

ŷ = c + mx

Here c = intercept ; y = response variable ;x = explanatory variable and m = slope or gradient.

Hence, mx = 0.2x

Where m = 0.2

The slope means :

Change in y / change in x

Changes in the response variable with respect to change in the explanatory variable.

The slope is positive meaning an increase in the thickness will result in a corresponding increase in price.

With a 0.2 gradient value, that means there is an $0.2 average increase in price of soap as the thickness increases by 1 cm.

Answer:

The price of the soap increases by $0.20, on average, when the thickness increases by 1 cm.

Step-by-step explanation:

Cross multiply the numbers in the matrix:

1 *2 + 5*x = -13

Simplify:

2 + 5x = -13

Subtract 2 from both sides:

5x = -15

Divide both sides by 5

X = -15/5

X = -3

Because it’s absolute value it needs to be positive so x = 3

Answer:

There is sufficient evidence to support the claim that the mean temperature is different from 42 deg

Step-by-step explanation:

From the given information, we are being told that:

The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, μ, of 42°F

i. e  mean  μ = 42

The owner of the brewery does not agree with the refrigerator manufacturer, and claims he can prove that the true mean temperature is incorrect.

Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.

From above;

The null and the alternative hypothesis can be computed as:

[tex]\mathbf{H_o : \mu = 42} \\ \\ \mathbf {H_1 : \mu \neq 42}[/tex]

Here , the hypothesis test of the claim is the alternative hypothesis.

The conclusion based on the decision rule:  is to reject the null hypothesis

∴

The conclusion in non technical terms is that :

There is sufficient evidence to support the claim that the mean temperature is different from 42 deg

Answer:

Step-by-step explanation: 2y+18 = y+39

y=21

Answer:

y = 21

Step-by-step explanation:

In the figure , 2y + 18 and y + 39 are opposite interior angles . We know that opposite interior angles are equal , so

2y + 18 = y + 39

=> 2y - y = 39 - 18

=> y = 21

Answer:

There is no sufficient evidence to support the executive claim

Step-by-step explanation:

From the question we are told that

     The  population proportion is  [tex]p = 0.48[/tex]

      The  sample proportion is  [tex]\r p = 0.45[/tex]

       The sample  size is  [tex]n = 300[/tex]

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

The null hypothesis is  [tex]H_o : p= 0.48[/tex]

The  alternative hypothesis is  [tex]H_a : p \ne 0.48[/tex]

   Generally the test statistics is mathematically evaluated as

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

=>        [tex]t = \frac{0.45 - 0.48 }{ \sqrt{ \frac{0.48 (1 - 0.48 )}{300} } }[/tex]

=>       [tex]t = -1.04[/tex]

The  p-value is mathematically represented as

     [tex]p-value = 2P(z > |-1.04|)[/tex]

Form the z-table  

                 [tex]P(z > |-1.04|) = 0.15[/tex]

=>   [tex]p-value = 2 * 0.15[/tex]

=>   [tex]p-value = 0.3[/tex]

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

   Hence we can conclude that there is no sufficient evidence to support the executive claim
