Correct on Edge 2021
The correct option is 4. (0,4)
Given inequalities are [tex]y\geq \frac{1}{2} x^{2} +4[/tex] and [tex]y< \sqrt{x+2}+6[/tex] .
Taking first inequality,
[tex]y\geq \frac{1}{2} x^{2} +4[/tex]
Or, [tex]y=\frac{1}{2} x^{2} +4[/tex]
now checking which option satisfy the above equation.
Taking option 1.(–2, 6)
on putting x= - 2 and y=6, we get
[tex]6= \frac{1}{2} (-2)^2+4[/tex]
[tex]6=6[/tex]
Hence option 1 (–2, 6) satisfy the equation.
Similarly checking for option 2 and 3 we find that these options totally not follow inequality, so option 3 and option 2 must not be the solution of given inequality.
Now option 4 (0, 4).
Putting x=0 and y = 4, we get
[tex]4=0+4\\4=4[/tex]
Hence option 4 also satisfy the first inequality.
Now we have two option to choose our final answer option 1 and option 4.
since option 4 lies in the shaded region so option 4 will be correct option.
Hence the correct option is 4. (0,4)

What is the solution to this system of equations?
x − 2y = 15
2x + 4y = -18
A. x = 1, y = -6
B. x = 1, y = -7
C. x = 3, y = -6
D. x = 3, y = -7
Answers
Answer:
C. x = 3, y = -6 is the answer.
Step-by-step explanation:
1. Isolate x for x = 2y = 15 -> x = 15 + 2y
2. Substitute x = 15 + 2y -> [2 (15 + 2y) + 4y = -18]
3. Simplify -> [30 + 8y = -18)
4. Isolate y for 30 + 8y = -18 -> y = -6
5. For x = 15 + 2y, substitute y = -6 -> x = 15 + 2(-6)
So, x = 3 and y = -6 are the solutions to this system of equations.

Answers
Answer:
h = 5(tane)
Step-by-step explanation:
The diagrammatic representation of the question given is attached below ;
The height of the light pole, h = opposite side
Adjacent side = 5 feets
Angle of elevation = e
Using trigonometry ;
Tan e = opposite / Adjacent
Tan e = h / 5
Making h the subject ;
h = 5(tane)

The question is asking to write an algebraic expression for the sum of a number and 45. We know we are adding a number to 45. So we use addition. But, we don't which number we are adding to 45.

Which expression can be used to find the height of the cone below?
V = 30ft³ B = 80ft²
A.30 = 1/3(8h)
B.8 = 30h
C.30 = 8h
D.8= 1/3(30h)
Answers
Answer:
A. 30 = ⅓(8h)
Step-by-step explanation:
Volume of cone (V) = 30 ft³ (given)
Base area (BA) = 8 ft² (given)
height = ?
Formula for volume of a cone = ⅓*B.A*h
Plug in the values into the equation
30 = ⅓*8*h
30 = ⅓(8h)
Expression to find the height will be 30 = ⅓(8h)

A laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with s = 17.6 milligrams. A confidence interval of 173.8 mg < μ < 196.2 mg is constructed for the true mean cholesterol content of all such eggs. It was assumed that the population has a normal distribution. What confidence level does this interval represent?
Answers
Answer:
The appropriate solution is "95%".
Step-by-step explanation:
The given values are:
Lower bound,
= 173.8
Upper bound,
= 196.2
Mean of cholesterol,
= 138 milligrams
S = 17.6 mg
Now,
The margin of error (E) will be:
= [tex]\frac{Upper \ bound-Lower \ bound}{2}[/tex]
= [tex]\frac{196.2-173.8}{2}[/tex]
= [tex]\frac{22.4}{2}[/tex]
= [tex]11.2[/tex]
As we know,
⇒ [tex]E=t_{\alpha 12}\times \frac{S}{\sqrt{n} }[/tex]
On putting the values, we get
⇒ [tex]11.2=t_{\alpha 12}\times \frac{17.6}{\sqrt{12} }[/tex]
On applying cross-multiplication, we get
⇒ [tex]t_{\alpha 12}=2.2044[/tex]
∴ [tex]\frac{\alpha}{2} =0.025[/tex]
[tex]\alpha = 0.025\times 2[/tex]
[tex]=0.05[/tex]
hence,
The confidence level will be:
⇒ [tex]CI=1-\alpha[/tex]
⇒ [tex]=1-0.05[/tex]
⇒ [tex]=0.95[/tex]
⇒ [tex]=95[/tex]%

Answers
Answer:
1/4, or 0.25 inches
Step-by-step explanation:
You count the dots. The number of dots tell you how many of each length of string she used.
You first find the column with the most dots, and then you find the column with the least. Then you just subtract them, the number of inches it displays on the bottom, 12 1/2 - 12 1/4, which is 1/4. I did this in my head and you can use a calculator if you want.
