Answer:
n = 6
Step-by-step explanation:
2 = [tex]\frac{n}{3}[/tex]
multiply both sides by 3
=> n = 6
Answer:
n = 6
Step-by-step explanation:
If 2 = n/3, then n = 6, because 3 times 2 is 6 (2 of 3 is 6)

Answer:
[tex]y\leq -6[/tex]
Step-by-step explanation:
[tex]\frac{1}{2}y \leq -3[/tex]
Our inequality requires first to solve for y.
To solve for a variable, we must isolate it.
In this case, first, we can multiple by the inverse of the fraction which is 2.
[tex]\frac{1}{2}y\leq -3\\[/tex]
[tex]2(\frac{1}{2}y)\leq -3(2) \\[/tex]
1*y=y and -3*2=-6
So our inequality stands like this -
[tex]y\leq -6[/tex]

A circular flower garden has a radius of 19 ft that
has to be mulched. Each bag of mulch covers 32square feet. How
many bags of mulch are needed? Use TI = 3.14. Round to the
nearest whole number
Step-by-step explanation:
[tex]area \: of \: garden = \pi {r}^{2} \\ = 3.14 \times {19}^{2} \\ = 1133.54 \: {ft}^{2} \\ number \: of \: bags = \frac{area \: of \: garden}{area \: covered\: by \: bag} \\ = \frac{1133.54}{32} \\ = 36 \: bags[/tex]

Step-by-step explanation:
You wish to test H 0 : μ d = 0 versus H a : μ d < 0 at a significance level of 0.10. For the context of this problem, μ d = μ 2 − μ 1 where the first data set represents a pre-test and the second data set represents a post-test. You obtain pre-test and post-test samples for n d = 28 subjects. The average difference (post - pre) is ¯ x d = − 4.3 with a standard deviation of the differences of s d = 45.5 .
What is the test statistic?
Answer:
0.5
Step-by-step explanation:
Given :
H0 : μd = 0 VS H1 : μd ≠ 0
Test statistic :
xd / (sd ÷ √n)
Where ;
xd = mean difference = -4.3
sd = standard deviation of difference = 45.5
n = sample size = 28
The test statistic is thus :
-4.3 / (45.5 / √28)
-4.3 / 8.5986917
= 0.5000760
Hence, test statistic = 0.5

A writer buys a new laptop for $1866. Every year the laptop decreases in value by 20%.
Answer:
the answer is A
A function that represents a $1866 laptop that decreases in value by 20% each year is f(n)=1866(1.2)ⁿ.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that,
$1866 laptop that decreases in value by 20% each year.
Here, f(n)=1866(1+20%)ⁿ, where n is the number of years
f(n)=1866(1+20/100)ⁿ
f(n)=1866(1.2)ⁿ
Therefore, a function that represents a $1866 laptop that decreases in value by 20% each year is f(n)=1866(1.2)ⁿ.

A cylinder soup has a radius of 1,6 in and is 5/7 in. tall what is the volume
Answer:
[tex]V=0.0623\ inch^3[/tex]
Step-by-step explanation:
Given that,
The radius of cylinder, r = 1/6 inch
The height of the cylinder, h = 5/7 inch
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\=3.14\times (\dfrac{1}{6})^2\times \dfrac{5}{7}\\\\V=0.0623\ inch^3[/tex]
So, the volume of the cylinder is equal to [tex]0.0623\ inch^3[/tex].

a cylinder shaped water pitcher has a radius of 5 inches and a height of 12.5 inches find the surface area of the pitcher
A.5495 in² B. 54.95 in²
C.549.5 in² D. 5.495 in²
A cylinder shaped water pitcher has a radius of 5 inches and a height of 12.5 inches. Find the surface area of the pitcher.
Answer:-Given:-[tex] \bullet [/tex] Radius (r) of a cylinder shaped water pitcher = 5 inches.
[tex] \bullet [/tex] Height (h) of a cylinder shaped water pitcher = 12.5 inches.
To Find:-The surface area of the pitcher.
Solution:-We know,
Formula of Surface area of a cylinder is 2πr(r + h) sq. units.
So,
Surface area of the pitcher = 2 × 3.14 × 5(5 + 12.5)
Surface area of the pitcher = 31.4 × 17.5
Surface area of the pitcher = 549.5 in²
[tex] \therefore [/tex] The surface area of the pitcher is 549.5 in².
Hence, the option (C) 549.5 in² is correct. [Answer]
The surface area of the cylinder is 549.50 in².
What is the surface area of the cylinder?A cylinder is a three-dimensional object. It is made up of a prism with a circular base. The total surface area is the sum of the areas of the faces or surfaces of a 3-dimensional object
Total surface area = 2πr(r + h)
Where:
π = 3.14r = 5 h = height2 x 3.14 x 5 (5 + 12.5) = 549.50 in²
Ann's rent increased from $1,200 to $1,350.
By what percent did her rent increase?
Answer: Percentage increase: 12.5%
Step-by-step explanation: (EXAMPLE) percentage increase/decrease = (Vnew - Vold) / Vold × 100%
Example #1
Price percentage increase from old value of $1000 to new value of $1200 is caluclated by:
percentage increase = ($1200 - $1000) / $1000 × 100%
= 0.2 × 100% = 20%
Answer:
12.5%
Step-by-step explanation:
1350 - 1200 / |1200| × 100% =
150 / 1200 × 100 = 12.5%

Historically, about 53% of the population of a certain country believed that the planet's temperature was rising ("global warming"). A March 2010 poll wanted to determine whether this proportion had changed. The poll interviewed adults in the population, and said they believed that global warming was real. (Assume these adults represented a simple random sample.)
Required:
a. What percentage in the sample believed global warming was real in 2010?
b. Is this more or less than the historical 57%?
Answer:
(a) The proportion is 61.23%
(b) It is more than the historical 57%
Step-by-step explanation:
This question has missing details, and they are:
[tex]n = 926[/tex] ---- The Sample Adults
[tex]x = 567[/tex] -- Those that believe global warming was real
Solving (a): The proportion of those that believe.
This is calculated as:
[tex]p = \frac{x}{n}[/tex]
Substitute values for x and n
[tex]p = \frac{567}{926}[/tex]
[tex]p = 0.6123[/tex]
Express as percentage
[tex]p = 0.6123 * 100\%[/tex]
[tex]p = 61.23\%[/tex]
Solving (b) More or less than 57%
By comparison:
[tex]61.2\% > 57\%[/tex]
Hence, it is more than the historical 57%
