-------------------------------\\\\
h(x)= 2^x  \qquad 
\stackrel{2\le x\le 4}{\begin{cases}
x_1=2\\
x_2=4

Part a) In 35 minutes, 25 number of pages have been read.

Part b) There is positive association between time and the number of pages being read

Step-by-step explanation:

Part a) What is the meaning of the point (35,25)

35 is the value of x-axis and 25 is the value of y-axis

x-axis represent Time(minute) while y-axis represent Number of pages read

So, in 35 minutes, 25 number of pages have been read.

Part b) Is the association between time and number of pages positive or negative? state the association in terms of variables.

Association is positive if increasing one variable, other variable is also increasing.

Association is negative if increasing one variable, other variable is decreasing.

In the given graph, the association is positive. Increasing the time, the number of pages being read are also increasing.

if time is 20 minutes, number of pages read are 12.5. if time is 25 minutes then number of pages read are 17

So, there is positive association between time and the number of pages being read.

Let f(x)=x+3 and g(x)=1/x. The graph of (f*g)(x) is shown below.
Vlad [161]
For this case we have the following functions:
 f (x) = x + 3

g (x) = 1 / x When composing the functions we have:
 (fog) (x) = f (g (x))

 Substituting values we have:
 (fog) (x) = ((1 / x) +3)

 Rewriting:
 (fog) (x) = 1 / x + 3

 The function has a horizontal asymptote at y = 3.
 Therefore, the range of the function is all reals minus y = 3.

As part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at rando
Inga [223]

Answer:

Option a is right

Step-by-step explanation:

Given that as part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at random concerning their monthly credit card balance.

Sample average = 2573

Variance = 4252

Sample size = 35

STd deviation of X = \sqrt{4252} \\=65.21

Score of student selected at random X=1700

Corresponding Z score = \frac{1700-2573}{65.201} \\=-13.38

Rounding of we get Z score = -13.4

option a is right

Write the equation of a circle for which the endpoints of a diameter are (-2,-2) and (4,-10)
Maurinko [17]

Answer:

Therefore the required Equation of Circle

x^{2}+y^{2}-2x+12y+12=0

Step-by-step explanation:

Given:

End point of Diameter be

point A( x₁ , y₁) ≡ ( -2 ,-2 )

point B( x₂ , y₂) ≡ ( 4 , -10 )

To Find:

Equation of a circle =?

Solution:

When end points of the Diameter are A( x₁ , y₁) , B( x₂ , y₂). then the Equation of Circle is given as

(x-x_{1})(x-x_{2})+(y-y_{1})(y-y_{2})=0

Substituting the end point are

(x-(-2))(x-4)+(y-(-2))(y-(-10))=0\\(x+2))(x-4)+(y+2))(y+10))=0\\

Applying Distributive Property we get

x^{2} -2x-8+y^{2}+12y+20 =0\\\\x^{2}+y^{2}-2x+12y+12=0

Therefore the required Equation of Circle

x^{2}+y^{2}-2x+12y+12=0
