Answer:
h = 3 cm
Step-by-step explanation:
Given that,
Diameter, d = 6 cm
Radius, r = 3 cm
Volume of the cone, V = 28.26 cm³
The formula for the volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2 h\\\\h=\dfrac{3V}{\pi r^2}\\\\h=\dfrac{3\times 28.26}{3.14\times 3^2}\\\\h=3\ cm[/tex]
So, the height of the cone is equal to 3 cm.

Answer:check my profile and answer my question
Step-by-step explanation:
plz
Total number of car repairing jobs is 28 cars
Given that;Number of operating hours = 8 hours
Number of total workstation = 7
Average automobile repair job = 2 hours
Find:Total number of car repairing jobs
Computation:Total number of car repairing jobs = [Number of operating hours × Number of total workstation] / Average automobile repair job
Total number of car repairing jobs = [8 × 7] / 2
Total number of car repairing jobs = 56 / 2
Total number of car repairing jobs = 28 cars

How do I solve for n and m using special right triangle rules.
Answer:
Because the triangle is a 45-45-90 triangle, the n and m should be the same lengths. For these types of triangles, the hypotenuse is [tex]x\sqrt{2}[/tex] and the side lengths are x. Because we are given the length of the hypotenuse, we need to find the x-value. The equation should be 6=[tex]x\sqrt{2}[/tex]. Simplify to get x=[tex]3\sqrt{2}[/tex]. So, the length of n and m should both be [tex]3\sqrt{2}[/tex].

The Hutton's records for the past six months show that their expenditures totaled $2.768, $3,001, $2,663, $2,471, $2,893, and $2,803. What is their average monthly expenditure for the six months?
Answer
2766.5
Step-by-step explanation:
Well to solve for average all you have to do is add the values together then divide by the number of values you started with. So we add them together(2768+3001+2663+2471+2893+2803) and get 16599. Then, since there were 6 values we divide that by 6 and you get your answer.

A train can accommodate at most 80 passengers, economy class (x) and firstclass (y) passengers. To avoid making a loss the train must carry at least ten
economy class passengers and at least twenty first class passengers. Due to the
number of complementary items the first-class passengers receive, the number
of first-class passengers should be at most three times the number of economy
class passengers.
First class tickets cost N$5000 while economy class tickets cost N$3000.

Two angles are said to be complementary if the some of those two angles is equal to 90°
Given : ∠WXY and ∠YXZ are complementary angles
⇒ ∠WXY + ∠YXZ = 90°
Given : ∠WXY = (2x + 5)° and ∠YXZ = (8x - 5)°
⇒ (2x + 5)° + (8x - 5)° = 90°
⇒ 10x = 90°
⇒ x = 9°
Substituting the value x = 9° in angles ∠WXY and ∠YXZ, we get :
⇒ ∠WXY = 2(9) + 5 = 18 + 5 = 23°
⇒ ∠YXZ = 90° - 23° = 67°

The movie theater sells adult tickets for $10 and kids
tickets for $8. They sold $176 worth of tickets last Tuesday with a total of 20 ticket sales.
Use the graph to determine the number of adult tickets
and kids tickets sold.
number of adult tickets:
number of kids tickets:
Answer:
On Tuesday 8 adult tickets and 12 child tickets were sold.
Step-by-step explanation:
Since the movie theater sells adult tickets for $ 10 and kids tickets for $ 8, and they sold $ 176 worth of tickets last Tuesday with a total of 20 ticket sales, to determine how many tickets of each type were sold, the following calculation must be performed:
10 - 8 = 2
20 x 8 = 160
176 - 160 = 16
16/2 = 8
8 x 10 + 12 x 8 = X
80 + 96 = X
176 = X
Therefore, on Tuesday 8 adult tickets and 12 child tickets were sold.

A sphere has a radius of 9 in, which means its volume is 972π in3. The sphere is dilated by 2⁄3. What is the volume of the new sphere?
Answer:
08-Oct-2009 — If a spherical balloon has a volume of 972 pi cubic centimeters, what is ... is 4.pi.r^2 (its area remember not volume) as 4/3.pi.r^3=972pi r=9 ... and it is good to know the squares of the next 10 numbers.
Answer:
I have this same question on my math test.
Since the radius is 9, the diameter is 18.
The shape is being dilated by 2/3, so the new radius is 6.
Volume formula: V = 4/3πr^3
So now we plug in the values.
V = 4/3 x π x (6)^3
V = 4/3 x π x 216
V = 288π
If the answers do not have the pi symbol present, then it has been multiplied into the answer.
288 x 3.14 = 904.32
The new volume of the sphere is 904.32 in^3
A population has a mean of 180 and a standard deviation of 24. A sample of 100 observations will be taken. The probability that the mean from that sample will be between 183 and 186 is _____.
Answer:
The probability that the mean from that sample will be between 183 and 186 is 0.0994 = 9.94%.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
A population has a mean of 180 and a standard deviation of 24.
This means that [tex]\mu = 180, \sigma = 24[/tex]
A sample of 100 observations will be taken.
This means that [tex]n = 100, s = \frac{24}{\sqrt{100}} = 2.4[/tex]
The probability that the mean from that sample will be between 183 and 186 is:
This is the pvalue of Z when X = 186 subtracted by the pvalue of Z when X = 183. So
X = 186
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{186 - 180}{2.4}[/tex]
[tex]Z = 2.5[/tex]
[tex]Z = 2.5[/tex] has a pvalue of 0.9938
X = 183
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{183 - 180}{2.4}[/tex]
[tex]Z = 1.25[/tex]
[tex]Z = 1.25[/tex] has a pvalue of 0.8944
0.9938 - 0.8944 = 0.0994
The probability that the mean from that sample will be between 183 and 186 is 0.0994 = 9.94%.
