Answer:
Probability that 32 or more from this sample used Internet Explorer as their browser is 0.9015.
Step-by-step explanation:
We are given that according to Net Market Share, Microsoft's Internet Explorer browser has 53.4% of the global market.
A random sample of 70 users was selected.
Let 
= <u><em>sample proportion of users who used Internet Explorer as their browser.</em></u>
The z score probability distribution for sample proportion is given by;
Z = 
~ N(0,1)
where, p = population proportion of users who use internet explorer = 53.4%
= sample proportion = 
= 0.457
n = sample of users = 70
Now, probability that 32 or more from this sample used Internet Explorer as their browser is given by = P( 
0.457)
P( 0.457) = P( 
) = P(Z -1.29)
= P(Z 
1.29) = <u>0.9015</u>
The above probability is calculated by looking at the value of x = 1.29 in the z table which has an area of 0.9015.

Answer:
The given statement is false.
Step-by-step explanation:
Reason
let D be a directed graph with 'n' no of vertices and 'E' edges.
where 'n'=1. thus D =(n,E).
In degree: in directed graph the number of incoming edges on a vertex is known as indegree.
it is denoted as deg ⁺(n).
And now we know that in a directed graph
if deg ⁻(n)= deg ⁺(n) for each vertex n.
Answer:
Length of Bar JK=l
Bar (JK) is dilated by a scale factor of n, having origin as the center of dilation.
New line segment formed named bar (J'K').
As given slope of bar(JK) =m
When we dilate a line segment with respect to origin , having origin as the center of dilation, there is no effect of slope on Dilation.
Length of bar (J'K')= (Length of bar JK)×(Scale factor)
= l×n Or n×l
Option (D) is correct.
19/4 = 4 3/4 ft which is less than 5ft
