Let's solve this inequality!
What can we do to solve this inequality? Well, first of all, we can add -7 and 35:
Now, move 20 to the right, using the opposite operation:
Subtract:
Divide both sides by -1 to isolate x:
(Answer)
_____________
<em>Additional comment</em>
When we divide both sides of an inequality by a negative number, we flip the inequality sign.

Answer:
(27.3692 ; 44.6308)
Step-by-step explanation:
Mean, xbar = 36
Standard deviation, s = 11
Sample size, n = 12
Tcritical at 0.2, df = 12 - 1 = 11 ; Tcritical = 2.718
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/sqrt(n)
Margin of Error = 2.718 * 11/sqrt(12) = 8.6308
Confidence interval :
Lower boundary : 36 - 8.6308 = 27.3692
Upper boundary : 36 + 8.6308 = 44.6308
(27.3692 ; 44.6308)
The area of a square is simply the side length squared and we are given that the area is 125 so:
s^2=125
s=√125
s=5√5
Now using the area equation again, and adding 1 inch to s we have:
A=(s+1)^2, and using s found above we have:
A=(5√5+1)^2
A=125+10√5+1
A=126+10√5 in^2
A≈148.36 in^2 (to nearest hundredth of a square inch)
Answer:
90.25π
Step-by-step explanation:
The circumference of circle is 2πr, or in other words the diameter times π.
The area of a circle is πr^2.
19π is the circumference of this circle.
So, 19 is the diameter, and 9.5 the radius.
The area if (9.5^2)π.
9.5^2=90.25
So, in terms of π, the area of the circle is 90.25π.
