Answer:

D) 89.6 %

Average  or mean of the given data = 89.6 %

Step-by-step explanation:

Step(i):-

Given data

        X      :     82        100        84

P(X=x)       :    0.40      0.40     0.20

Step(ii)

Let 'X' be the discrete distribution

Mean of the discrete distribution = ∑ x P( x=x)

                                                       = 82 ×0.40 +100 ×0.40 +84 ×0.20

                                                       = 89.6

Final answer:-

Average of the given data = 89.6 %

Answer:

V = 150π units^3

Step-by-step explanation:

The volume of this cylinder is V = πr²h = π(5 units)^2·(6 units), or

V = 150π units^3

The volume of the given cylinder as shown in the diagram is 150π cube units or 471 cube units.

The volume of a solid is the total space it contains in the three-dimensional space.

The volume of a cylinder can be given by the formula,

V = πr²h cube units,

where V is the volume, r is the radius of the base of the cylinder, and h is the height of the cylinder.

In the question, we are asked to find the volume of the cylinder shown in the figure.

The cylinder has a base radius (r) of 5 units, and height (h) of 6 units.

So, we can find its volume using the formula,

V = πr²h cube units,

where V is the volume, r is the radius of the base of the cylinder, and h is the height of the cylinder.

∴ The volume of the cylinder = π(5²)6 cube units

or, the volume of the cylinder = π*25*6 cube units

or, the volume of the cylinder = 150π cube units

or, the volume of the cylinder = 150*3.14 cube units = 471 cube units.

∴ The volume of the given cylinder as shown in the diagram is 150π cube units or 471 cube units.

Answer:

So Jeff is faster with 7 km per hour

Step-by-step explanation:

Jeff says I can run 7 kilometers per hour!

Cameron says "I can run 100 meters per minute!!

To actually know which one of them is the fastest we will convert their speed to be in the same unit

Let's convert meters per minute to kilometers per hour

100 meters per minute= 100 M/m

100 meters per minute= 100 *60/1000

100 meters per minute= 6000/1000

100 meters per minute= 6 km /h

100 meters per minute= 6 kilometers per hour

[tex]\huge \boxed{\mathrm{12}}[/tex]

Step-by-step explanation:

R is a point on the line segment QS.

QR = 2

RS = 10

QS = 2 + 10

QS = 12

The length of the line segment QS is 12 units.

Given that, point R is on the line segment QS. Given QR =2 and RS = 10.

We need to determine the length of QS.

A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions.

Here, since R is in between QS, QS=QR+RS

=2+10=12 units

Therefore, the length of the line segment QS is 12 units.

first you group like terms.

-3s-s+8+1-2

-4s+7

Answer:

-4s + 7

Step-by-step explanation:

We need to combine like terms. Like terms are terms whose variables (and exponents) are the same (note that they could be constants as well). Basically, they are "like" each other. In this case, the like terms are -3s and - s and also 1, 8, and -2. -3s - s = -4s and 1 + 8 - 2 = 7 so the answer is -4s + 7.

Answer:

The  probability is  [tex]P(14 < X < 20 ) = 0.5354[/tex]  

Step-by-step explanation:

From the question we are told that

   The  proportion that live with their parents is  [tex]\r p = 0.142[/tex]

   The  sample  size is n =  125

Given that there are two possible outcomes and that this outcomes are independent of each other then we can say the Recent census data follows a Binomial distribution

  i.e  

       [tex]X \ \~ \ B( \mu , \sigma )[/tex]

Now the mean is evaluated as

      [tex]\mu = n * \r p[/tex]

      [tex]\mu = 125 * 0.142[/tex]

      [tex]\mu = 17.75[/tex]

Generally the proportion that are not staying with parents is  

      [tex]\r q = 1 - \r p[/tex]

= >    [tex]\r q = 0.858[/tex]

The standard deviation is mathematically evaluated as

     [tex]\sigma = \sqrt{n * \r p * \r q }[/tex]

     [tex]\sigma = \sqrt{ 125 * 0.142 * 0.858 }[/tex]

    [tex]\sigma = 3.90[/tex]

Given the n is large  then we can use normal approximation to evaluate the probability as follows  

     [tex]P(14 < X < 20 ) = P( \frac{ 14 - 17.75}{3.90} <\frac{ X - \mu }{\sigma } < \frac{ 20 - 17.75}{3.90} )[/tex]

Now applying continuity correction

      [tex]P(14 < X < 20 ) = P( \frac{ 13.5 - 17.75}{3.90} < \frac{ X - \mu }{\sigma } < \frac{ 19.5 - 17.75}{3.90} )[/tex]

Generally  

    [tex]\frac{ X - \mu }{\sigma } = Z ( The \ standardized \ value \ of X )[/tex]

    [tex]P(14 < X < 20 ) = P( \frac{ 13.5 - 17.75}{3.90} < Z< \frac{ 19.5 - 17.75}{3.90} )[/tex]

     [tex]P(14 < X < 20 ) = P( -1.0897 < Z< 0.449 } )[/tex]

    [tex]P(14 < X < 20 ) = P( Z< 0.449 ) - P(Z < -1.0897)[/tex]

So  for the z -  table  

         [tex]P( Z< 0.449 ) = 0.67328[/tex]

         [tex]P(Z < -1.0897) = 0.13792[/tex]

 [tex]P(14 < X < 20 ) = 0.67328 - 0.13792[/tex]    

  [tex]P(14 < X < 20 ) = 0.5354[/tex]

5 + 1 - 12 = 2(1) - 7

Combine like terms

-6 = -5

Since -6 does equal -5 the answer is not 1

                 0                  

5 + 0 - 12 = 2(0) - 7

Combine like terms

-7 = -7

Hey, there!!

I hope you mean to subtract (-137) +(-43) from sum of -103 and 27.

First, add -103 + 27

[tex] = - 103 + 27[/tex]

[tex] = - 76[/tex]

{As ( minus + plus )= subtracts with sign which has greator value. }

now,

[tex]( - 137) + ( - 43) = - 180[/tex]

{ minus + minus = add with minus sign}.

Now, subtracting -180 from -76.

=(-76) - (-180 )

Now, multiply the sign (- × -)= +

so, -180 becomes +180

= -76+180

= 104..... is answer.

Hope it helps...

Answer:

104

Step-by-step explanation:

With what you provide, the expression would be:

[tex](-103+27)-(-137+-43)[/tex], which equals to:

[tex](-76)-(-180)= (-76)+(180)=104[/tex].      [negative minus a negative equals positive]

So, the answer would be 104.

The definition of a limit is the value a function it is approaching as the limit approaches a certain point.

We have the limit:

[tex]\lim_{x\to3} f(x)=5[/tex]

In other words, the value of f(x) as x approaches 3 approaches 5.

We do not care what happens at x=3. Rather, the limit tells us that as x approaches or gets closer to x=3, the function f(x) gets closer to 5.

Comparing with the regression equation formula: ŷ = mX + c

Where :

ŷ = predicted variable (Diastolic)

m = 6.69 = gradient or slope of the regression line

c = - 706.18 = intercept ( where the regression line intersects the y-axis).

2.) What is the best predicted diastolic pressure for a person with a systolic reading of 146
