The percent of questions she answered correctly is 80%.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Given;
Lana correctly answered 48 of 60 questions on a math exam
Now,
=48*100/60
=480/60
=80
Therefore, the percentage will be 80%.

Step 2: Find distance d
Simply plug in the 2 coordinates into the distance formula to find distance d.
Substitute [DF]: [tex]d = \sqrt{(5-9)^2+(-3-3)^2}[/tex]Subtract: [tex]d = \sqrt{(-4)^2+(-6)^2}[/tex]Exponents: [tex]d = \sqrt{16+36}[/tex]Add: [tex]d = \sqrt{52}[/tex]Simplify: [tex]d = 2\sqrt{13}[/tex]Find the shaded area. Use 3.14 as the approximate value of pi.
Answer:
164.73 cm²
Step-by-step explanation:
Area of the shaded area = area of semi-circle - area of the triangle
Area of the semi-circle:
Area = ½(πr²)
r = ½ of 34 = 17 cm
π = 3.14
Area = ½(3.14 × 17²)
Area = 453.73 cm²
Area of the triangle:
Area = ½*b*h
b = 34 cm
h = 17 cm
Area = ½ × 34 × 17
Area = 289 cm²
Area of the shaded area = 453.73 - 289 = 164.73 cm²

a. I and II
b. ll only
c. I and III
d. Ill only
Answer:
The answer is D, lll only.
Step-by-step explanation:
Just took the test on e d g e!
The statement that most directly applies to capitalism is III only.
Option D is the correct answer.
What is capitalism?It is a system of the economy where means of production and distribution are owned by the private, not the government.
We have,
The economic system of capitalism is characterized by private ownership of the means of production and distribution of goods and services, as well as the profit motive as the driving force behind economic activity.
Based on this definition, statement III most directly applies to capitalism, as it highlights the central role of market forces in determining prices and availability of goods.
On the other hand,
Statement I, which suggests heavy government regulation of the industry, is not a typical feature of capitalism, as it implies a more interventionist approach by the government in the economy.
Capitalism generally favors a more limited role for the government in economic affairs, although some government regulations may still be present.
Statement II, which suggests that individuals can start some, but not all, kinds of enterprises, is also not a defining characteristic of capitalism.
In a capitalist system, individuals are generally free to start any kind of enterprise that they wish, provided they can obtain the necessary resources and meet any legal or regulatory requirements.
Therefore,
The statement that most directly applies to capitalism is III only.

21.6 Computer use. A random sample of 197 12th-grade students from across the United States was surveyed, and it was observed that these students spent an average of 23.5 hours on the computer per week, with a standard deviation of 8.7 hours. If we plan to use these data to construct a 99% confident interval, the margin of error will be approximately (a) 0.07. (b) 0.62. (c) 1.6. (d) 8.7.
Answer:
(c) 1.6
Step-by-step explanation:
Calculation for what the margin of error will be approximately
First step is to calculate Total hours spent
Total hours spent = (197 * 23.5 hours)
Total hours spent =4,625 hours
Second step is to find the square root of the sample size
Sample size=√197
Sample size=14.04
Third step is to divide the Standard deviation of 8.7 hours by square root of sample size of 14.04
= 8.7 hours /14.04
= 0.6196
Fourth step is to use the Z table to find Z value at 99% confidence
Z value at 99% confidence = 2.58
Last step is to calculate the Margin of error
Margin of error = 0.6196 * 2.58
Margin of error = 1.59857
Margin of error= 1.6 (Approximately)
Therefore what the margin of error will be approximately is 1.6

Step-by-step explanation:
Part A: The total cost of the order would be $14 multiplied by the amount of canteens, plus the shipping price of $2. This is what my expression represents.
Part B:
CJ's Order:
14(2) + 2 =
28 + 2
$30
Cameron's Order:

Find the volume of a region bounded by the functions y = 2x + 6, the y-axis, and the x-axis as it revolves
around the x-axis.
GRAPH !
V=
units3
(round to the nearest tenth)
The bounded region in question is a triangle in the second quadrant. The line y = 2x + 6 has intercepts (0, 6) and (-3, 0), so revolving the triangle about the x-axis forms a cone with height 3 and whose circular base has radius 6. Its volume would then π/3 • 6² • 3 = 36π ≈ 113.1 units³.
But you're probably supposed to use calculus. Using the disk method, the integral for the volume is
[tex]\displaystyle V=\pi\int_{-3}^0 (2x+6)^2\,\mathrm dx[/tex]
[tex]\displaystyle V=\pi\int_{-3}^0(4x^2+24x+36)\,\mathrm dx[/tex]
[tex]V=\pi\left(\dfrac43x^3+12x^2+36x\right)\bigg|_{-3}^0=\boxed{36\pi}[/tex]
as expected.

Find the measure of angle A.
Answer:
30 degrees
Step-by-step explanation:
Keep this in mind, ALL triangles must equal 180 degrees.
This is an acute triangle, hence one of the angles is 90 degrees. To find the other two angles, we must solve for x. Since we know the sum of all angles in this triangle must equal 180 degrees, we know for setting up our equation, all the angles should equal 180.
[tex]90 + (x+37) + (x+67) = 180\\[/tex]
Now solve for x by isolating x
[tex]2x + 194 = 180\\2x=-14\\x=-7[/tex]
Our x is -7, now that we know that the numerical value of x is -7, replace x with -7 for angle A.
-7 + 37 = 30
<A is 30 degrees.
Check your work
Plug in -7 where you see x.
[tex]90 + (x+37) + (x+67) = 180\\90 + (-7+37) + (-7+67) = 180\\90 + 30 + 60 = 180\\180 = 180[/tex]
Turns out this was a 30-60-90 triangle. ✅
