Answer:
Step-by-step explanation:
we have that

Using a graph tool
see the attached figure
The function represent a vertical parabola that open up
the vertex is a minimum-------> is the point (-0.5, -9.3)
The x-intercepts are the points when the y coordinate is equal to zero
The x-intercepts are the points (-3.5, 0) and (2.5, 0)
so
the function cross the negative x-axis at point
therefore, the answer is
(-4, 0) and (-3, 0)

Step-by-step explanation:
The given points are A(1,2,3), B(-2,0,5) and C(4,1,5). The triangle is represented in the attach file where the three possible median are length AE, BF, and CD. We determine the coordinate of point D,E and F using the midpoint equation which is for any point A(x,y,z) and point B(a,b,c), the midpoint D is determine by
.
Hence going by the above formula we determine the coordinate of point D,E and F
.
.
point E
.
.
Point F
.
.
To determine the length of each median line we use the formula for distance between two points which is express as
.
Using the above formula we determine the length of line AE,BF and CD.

For point BF

For point CD

Answer:
i worked some of it out
Step-by-step explanation:
1 mile = 5,280ft
1 hour = 8 miles
30 min = 4 miles
15min = 2 miles
7.5 (7min and 30 sec) = 1 mile
3.75(225 sec) =1/2 mile = 2,640ft
0.25(quarter of a mile) = 1,320ft
i just completely lost myself but if this helps then great! sorry if i wasted your time

I hope this helps!
Answer:

Step-by-step explanation:
Given : The probability that an adult was never in a museum is : p=0.10
The number of adults randomly surveyed: n = 60
In Binomial distribution , the formula to find the mean and the standard deviation is given by :-

Then , the mean and standard deviation of the number that were never in a museum will be :-
