HELP ANSWER BOTH PLEASE (╥﹏╥)​
pogonyaev

Answer:

a.) 61 square feet

b.) $152.50

Step-by-step explanation:

first you find the area for the rectangle

LxW=A

10x4=40

then you find the area for the triangle

(bxh)1/2=a

(6x7)1/2=21

-we get 7 from adding the height that we know (3ft) and using logic, a rectangle has equal parallel lines so the dotted line has to equal 4ft. so 3ft+4ft=7ft

then you add both areas together

40 square feet+21 square feet= 61 square feet

<em>Now</em><em> </em><em>for</em><em> </em><em>B</em><em>.</em><em>)</em>

as we know, the area of the room floor is 61sq feet. so by multiplying 2.5 and 61 you get the cost as $152.50

Ratling [72]

Answer:

The null hypothesis is given as H_o : p_1-p_2=0 while the alternate hypothesis is H_A: p_1-p_2\neq 0

Step-by-step explanation:

As per the the given data

p1=Proportion of Homeowners who would buy the security system

p2=Proportion of Renters who would buy the security system

As the null hypothesis states that there is no difference in the test thus it is given as

H_o : p_1-p_2=0

This states that there is no difference between the probabilities of the homeowners buying the security system and the renters buying the security system.

The Alternative hypothesis is the other possibility of the null hypothesis. i.e It negates the null Hypothesis and is given as

H_A: p_1-p_2\neq 0

How are discontinuities and zeros created in rational expressions
Marina86 [1]
I suppose that would just be when the numerator of the rational expression equals zero. Nothing special goes on with the graph in that case; there are simply x-intercepts at those values of x. 

<span>Discontinuities are created when the denominator of the rational expression equals zero (because division by zero is undefined). Graphically, this is usually represented by a dashed vertical line indicating a vertical asymptote. </span>
