Quadratic trinomals are in the form of x^2+bx+c
You need to find the factors of c that add up to b.
So the first question x^2+5x-14
You are looking for the factors (multiply) of -14 that add up to 5
You need to do the same for the next one. Factors of 3 that add up to -4
Those factors would be -3 and -1
That makes the factors (x-1)(x-3)

C.) 4.1*10-3=38 (4.1 * 10 = 41 & 41-3= 38)  <u>38 > 0.041</u> but i dont know i think this is also true its also written as 38>= 0.041 maybe printing mistake

D.) squareroot of 20 = 4.4 something is > 4

and any no like 3^0= also 1,

Whats a segment connecting midoints
I am Lyosha [343]

Answer:

A midsegment (or midline)

Step-by-step explanation:

In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.

Solution: We are given the population mean =42

Now, in order to find which shift's mean is closest to population mean, we will find the mean of each shift.

The mean of shift 1 is:

Mean=\frac{18+25+56+42+29+38+54+47+35+30}{10}=\frac{374}{10}=37.4

The mean of shift 2 is:

Mean=\frac{23+19+50+49+67+34+30+59+40+33&#10;}{10}=\frac{404}{10}=40.4

The mean of shift 3 is:

Mean=\frac{19+22+24+40+45+29+33+29+39+59  }{10}=\frac{339}{10}=33.9

The mean of shift 4 is:

Mean=\frac{21+23+25+40+35+19+70+40+22+23  }{10}=\frac{318}{10}=31.8

We clearly see the mean of shift 2 is close to the population mean. Hence the option B) Shift 2 is correct.
