Answer:

option:C

Step-by-step explanation:

A) on putting x=5 in equation x^2-5x+25=0 we have that the equation is not equal to 0 it gives the value 25. so {5} is not a solution set of A.

B) on putting x=5 in the equation x^2+10x+25=0 we have the equation is not equal to 0 it gives the value 100. so {5} is not a solution set of B.

C)on putting x=5 in the equation x^2-10x+25=0, the equation gives the value 0. so {5} is a solution set of C.

D)on putting x=5 in the equation x^2+5x+25=0 equation does not give the value zero it gives 75. so {5} is not a solution set for D.

Given that X ~ N(120, 35). We survey samples of 25 and are interested in the distribution of X-bar. Find the z-score associated
lubasha [3.4K]

Answer:

Option c -2.8571

Step-by-step explanation:

z-score are calculated as

z=\frac{xbar-mean}{\frac{S.D}{\sqrt{n} } }.

We are given that mean=120 and standard deviation=S.D=35 as X~N(120,35).

Sample size=n=25.

We have to find z-score for x-bar=100. So,

z-score=[100-120]/[35/√25]

z-score=[-20]/[35/5]

z-score=-20/7

z-score=-2.8571.

Thus,  the z-score associated with x-bar = 100 is -2.8571.

Solve for x: -7x+2=-4x-7
Zielflug [23.3K]

Answer: x = 3

Step-by-step explanation:

First you need to start by adding positive 4x to both sides since the 4x is a negative.  4x + (-7x) = -3x.  Then it is just simply -3x+2 = -7.  Since 2 is a positive number subtract both both sides by 2.  Then you should get -3x = -9.  Then divide both sides by -3 and the answer is x = 3.

If 4 workers take 900 hours to finish a project, how long will it take 8 workers to complete the same project?
butalik [34]

Answer: 350

Step-by-step explanation: If you multiply the amount of <em>workers</em> by two, then you divide the amount of <em>time </em>by two, and vice versa. So, in other words, whatever number you multiply the workers by, divide the time by that same number. I hope this helps!

iogann1982 [59]

Answer:

given sequence, -16; -9; -2: _

first term(a)=-16

common difference(d)=-9-(-16)=7

next term is 4

so

4th term=a+(n-1)d

=-16+(4-1)7=-16+21=5
