Any help will be nice...Dont answer for points >:( Correct equations for vertical line (7.5pt) Correct equations for horizont

al lines (7.5pt) 1. In many cities and towns across the United States, the numbering system of the roads is based on a grid, similar to the latitude and longitude lines on a globe. Suppose the green lines in the following graph represent two east-west and two north-south running roads in a Midwestern town.

Answer:

See below.

Step-by-step explanation:

Horizontal lines have the equation:

y=n

Where <em>n</em> is the value the horizontal line stays on.

Vertical lines have the equation:

x=n

Where <em>n</em> is the value the vertical line stays on.

For the two north-south lines, one of them stays on -5 and the other stays on 8. Therefore, the two vertical line equations are:

x=-5 \text{ and } x=8

For the two east-west lines, one of them stays on -7 and the other stays on 4.

Therefore, the two horizontal line equations are:

y=-7 \text{ and } y=4

Two students in your class, Ralph and Bobby, are disputing a function. Ralph says that for the function, between x = −1 and x =
marshall27 [118]

Answer:

Ralph and Bobby both are correct about slope. Because slope for both is 0.

Step-by-step explanation:

We are given a function that has two values of x's between x = −1 and x = 1.

And the average rate of change between x=-1 and x=1 is 0.

We know that x=-1 and x=1 are the points on x-axis.

If we joint x=-1 and x=1 points, we would get a straight line horizontal line on x-axis.

And note, the slope of a horizontal line is 0 always.

So, according to Bobby the graph goes up through a turning point, and then back down that means the point (-1,0) gets horizontally shift by 2 unit at (1,0).

Therefore, rise/run = 0/2, that is also equal to 0.

Therefore, Ralph and Bobby both are correct about slope.

Because slope for both is 0.

A sample of 1700 computer chips revealed that 51% of the chips do not fail in the first 1000 hours of their use. The company's p
hichkok12 [17]

Answer:

The answer is -1.2

Step-by-step explanation:

Recalling the standard deviation formula,

we have : σ = sqrt[ P * ( 1 - P ) / n ]

Where sqrt = square root

n = Number of derivative

Therefore,:

if, H0: p is not 48%  vs H1: p1 = 48%

 

 

standard deviation is:

σ = sqrt[ P * ( 1 - P ) / n ] = sqrt[ .48*.49/900 ] = .01666333+ z -score is (p-P)/σ

= (.51-.53)/.01666333

The answer therefore =  -1.2

 ICONCLUSION:

It can therefore be concluded that there is statistical evidence that the proportions are different. H0 accepted in the hypothesis.

A rectangle is inside a circle with a 5 cm radius.
MrRa [10]

Answer:  30.5 cm²

To get the the area of the rectangle all we have to do is:

Rectangle Area = 6 × 8 = 48 cm²

Same thing to the circle, multiply the radius and pi:

Circle Area = 3.14 x 5² = 78.5 cm²

We have to subtract the two areas to find the shaded area.

78.5 - 48 = 30.5 cm²

I hope this helps!
