Since the mean of the distribution is 110, and the distribution is normal, then 50% of the the people will have scores below 110.
Answer:
So, exists 5527200 different leadership structures.
Step-by-step explanation:
We know that four members from a 50 person committee are to be randomly selected to serve as chairperson, vicechairperson, secretary, and treasurer. The first perosn to be selected is the chairperson, the second to be selected as vice chairperson, the third is secretary, and the fourth is treasurer.
Since the order of the people is important to us, we have the following:
50·49·48·47=5527200
So, exists 5527200 different leadership structures.

7. xint=-7
yint=-5
Step-by-step explanation:
Answer:
D) 1/2
Step-by-step explanation:
<u>Dilation</u> : a type of transformation that makes the figure larger or smaller.
<u>Scale factor</u> : number or the conversion factor which is used to change the size of a figure without changing its shape.
Scale factor = dimensions of the new shape ÷ dimensions of the original shape
Given:
- Length of new figure P'Q' = 3 units
- Length of original figure PQ = 6 units
Therefore, scale factor = 3 ÷ 6 = 1/2
(4x^2 -25) /( 2x+5)
Factorise the numerator
((2x)^2 - (5)^2 ) / ( 2x+5)
Applying the Difference of squares
= ((2x +5)(2x -5))/ (2x+5)
(2x+5) cancels in both numerator and denominator
That implies ,
= (2x-5) , with restriction 2x+5 not equals to 0
or x not equals to -5/2
So the first one is the correct answer
(2x+5) , restriction , x not equals to -5/2
