Answer:
Step-by-step explanation:
hello :
the x-intercepts when : y=0 means : 2x²--8x+5 =0
∆ = b² -4ac a=2 and b= -8 and c= 5
∆ = (-8)² -4(2)(5) = 64-40 =24
∆ >0 this equation has two solutions so : two x-intercepts
4. X = about 25 ft.
5. X = 13.5 in.
6. B = 7.2 ft.

Answer:
<em>Another way to calculate the correlation coefficient </em><em>(r) </em><em>is to </em><u><em>multiply</em></u><em> the slope of the regression line by the </em><u><em>standard deviation</em></u><em> of </em><em>X</em><em> and then </em><u><em>divide</em></u><em> by the standard deviation of </em><em>Y</em><em>.</em>

Given that G is the midpoint of FH, then:
FG=GH
hence;
14x+25=73-2x
solving for x we get:
14x+2x=73-25
16x=48
x=48/16
x=3
therefore the length FG=14x+25 will be:
14*3+25
=67
hence FH will be:
FH=67*2=134
Answer:
7.8
Step-by-step explanation:
The diameter is the full length across a circle. The radius is always half the diameter. if you divide 15.6 by 2 (to get half), we get 7.8. If this does not answer the question, let me know so I can edit
