Answer:

ŷ = 6.69X - 706.18 ; ŷ = 270.56 ; B. The predicted value is not close to the actual diastolic reading.

Step-by-step explanation:

Systolic reading(x) :

117

134

150

113

138

113

144

145

Diastolic (y) :

85

74

86

55

75

80

106

841

Using the online regression calculator, the regression equation obtained using the data values provided above is:

ŷ = 6.69X - 706.18

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

X = 146

ŷ = 6.69(146) - 706.18

ŷ = 976.74 - 706.18

ŷ = 270.56

The predicted value, 270.56 is not close to the actual Diastolic reading of 91.0

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

So Jeff is faster with 7 km per hour

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.

Step-by-step explanation:

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.

$695+$95=$790

Leftover

$889-$790 =$99

he would have $99 leftover

The amount left over with Jean is given by the equation A = $ 99

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the amount left over be represented as A

Now , the equation will be

The cost of basic computer is = $ 695.00

The cost of printer is = $ 95.00

The amount saved in month of May = $ 157.00

The amount saved in month of June = $ 210.00

The amount saved in month of July = $ 377.00

The amount saved in month of August = $ 145.00

The total amount saved = $ 157.00 + $ 210.00 + $ 377.00 + $ 145.00

The total amount saved = $ 889

The total cost of computer and printer = $ 695 + $ 95

The total cost of computer and printer = $ 790

The amount of money left over with Jean A = total amount saved - total cost of computer and printer

Substituting the values in the equation , we get

The amount of money left over with Jean A = $ 889 - $ 790

The amount of money left over with Jean A = $ 99

Therefore , the value of A is $ 99

Hence , the amount left over is $ 99

OPTION B IS INCORRECT:

Although c is double b for x^2+8x+16, this rule is not applicable for the rest of the equations. C is double b for the  is 1.5 times that of b for x^2+6x+9, and for and for x^2+10x+25, c is 2.5 times b, and for x^2+12x+36, c is 3 times of b.

OPTION C IS CORRECT:

We can test this relationship based off of the information given.

for x^2+6x+9, c equals (6/2)^2 which is 9

for x^2+8x+16, c equals (8/2)^2 which is 16

for x^2+10x+25 c equals (10/2)^2 which is 25

and finally, for x^2+12x+36 c equals (12/2)^2 which is 36.

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
