Answer:
Step-by-step explanation:
Hello there!
The first thing we want to do is find the least common denominator which would be 20
so we multiply the denominator and numerator of the fractions on the left side by 4
3x4=12
5x4=20 -12/20x
1x4=4
5x4=20 so now we would have
once again we want to isolate the variable using inverse operations
to get rid of the 4/20 we subtract each side by 4/20
now we have
now we want to get rid of the -12/20
to do so we divide each side by -12/20 (or -.6 as a decimal to make it easier)
REMEMBER flip the equality sign
we're left with
Answer:
For this case we want to test if the the average monthly income of all students at college is at least $2000. Since the alternative hypothesis can't have an equal sign thne the correct system of hypothesis for this case are:
Null hypothesis (H0):
Alternative hypothesis (H1):
And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no

Answer:
3-a
Step-by-step explanation:
-3(-x+a) 7<5 when x=-1 ?
Answer:
U ={ Parallelograms}
A= { Parallelogram with four congruent sides}={ Rhombus,Square}
B ={ Parallelograms with four congruent angles} ={ Rectangle, Square}
So, AB= { Square}
So among all the parallelograms "Square" is the only parallelogram which has all congruent sides as well as all congruent angles.
Answer:
Yes this cleaner would be recommend.
Step-by-step explanation:
<em>This cleaner would be recommend because it kills </em><u><em>0.999%</em></u><em> of germs and when they mean </em><u><em>0.999%</em></u><em> it rounds up to </em><u><em>1%</em></u><em> = </em><u><em>100% </em></u><em>so that will mean that </em><u><em>0.999% </em></u><em>of the germs will be killed.</em>
<em>To be understood the 1% is equal to = </em><u><em>100%</em></u><em> but just has no zeros. So this will mean that the </em><u><em>0.999%</em></u><em> would be almost equal too </em><u><em>100%</em></u><em> </em>
