Answer:
- Circle X with radius 2 cm.
- Either of two lines parallel to AB.
Step-by-step explanation:
1. The definition of a circle is all the points in a plane that are at some radius r from a given point (the circle center). That is what you have, with a radius of 2 cm.
__
2. Parallel lines are the same distance apart everywhere. Each line will have two parallel lines at some given distance from it, one on each side. Here, the separation distance from AB is 1 cm, so your locus of points is the two lines parallel AB that are 1 cm from it on either side.

Step-by-step explanation:
Answer:
47.72% of the completion times is between 73.4 and 88.2 minutes
2.28% of the completion times is at most 58.6 minutes
Step-by-step explanation:
A reading test are normally distributed with a mean time of 73,4 minutes and a standard deviation of 7.4 minutes.

Standard deviation = 
A)Approximately what percent of the completion times is between 73.4 and 88.2 minutes i.e.P(73.4<x<88.2)
Formula : 
At x = 73.4

Z=0
Refer the z table for p value
p value = 0.5
At z = 88.2

Z=2
Refer the z table for p value
p value =0.9772
So,P(73.4<x<88.2)=0.9772-0.5=0.4772
So, 47.72% of the completion times is between 73.4 and 88.2 minutes
B)Approximately what percent of the completion times is at most 58.6 minutes i.e.
?


Z=-2
Refer the z table for p value
p value =0.0228
So,2.28% of the completion times is at most 58.6 minutes
Answer:
y=3x-5
Step-by-step explanation:
Slope intercept form is y=mx+b
m represents slope
b represents y-intercept
In the picture, 3 replaces m, so 3 is the slope of the line.
When (2,1) and (5,10) are graphed, the line intercepts -5 on the y axis.
-5 is the y-intercept.
So, (2,1) and (5,10) in slope-intercept form is 
Answer:


This means that the family must travel for at least 4 days.
<em></em>
Step-by-step explanation:
Given


Required
Determine and solve the inequality
The number of days is represented with D
So:
On any D number of days, the family would have covered a distance of 350 * D miles
If the total distance is at least 1400, then the inequality is:

[The term "At least" is used to represent <em>greater than or equal to</em>]

Divide through by 350



<em>This means that the family must travel for at least 4 days.</em>
