The value of x is 16 degrees and the measure of the arc DFG for circles of homework 2 are 1 6.056 times radius of circle.
What is the property of a straight angle?The property of straight angle says that, the angle of a straight line is equal to the 180 degrees.
It can also be define as the sum of all the angle made on the straight line is equal to the 180 degrees.
For the first problem, the line GE, which is the diameter of the circle has two angles over it (x-3) degree and (12x-25) degrees.
For the diameter GE the sum of these two angle will be equal to 180 degrees. Thus,
[tex](x-3)+(12x-25)=180\\x-3+12x-25=180\\13x-28=180\\13x=180+28\\x=\dfrac{208}{13}\\x=16^o[/tex]
The value of mDE will be equal to (12x-25) as it is verticle angle of mGF. Thus,
[tex]arcDE=(12x-25)\\arcDE=(12(16)-25)\\arcDE=167^o[/tex]
Similarly the value of mEF
[tex]arcEF=(x-3)\\arcEF=(16-3)\\arcEF=13^o[/tex]
Let the radius of the circle is R. Then the measure of arc DFG is equal to the sum of areDEF and arc GF. Thus,
[tex]arcDFG=\dfrac{2\pi R}{2}+\dfrac{2 \pi R \angle GHF}{360}\\arcDFG=\dfrac{2\pi R}{2}+\dfrac{2 \pi R (167^o)}{360}\\arcDFG=6.056R[/tex]
For the second problem, the angle MN and QO are equal due to the vertical angle property. Therefore,
[tex](10x-45)=(6x-1)\\10x-6x=-1+45\\4x=44\\x=11[/tex]
The value of mMN is,
[tex]MN=(10x-45)\\MN=(10(11)-45)\\MN=65^o[/tex]
The value of NP using the property of straight line for line segment MP can be given as,
[tex]NP=180-MN\\NP=180-65\\NP=115^o[/tex]
Thus, the value of x is 16 degrees and the measure of the arc DFG for circles of homework 2 are 1 6.056 times radius of circle.

What are the mean, variance, and standard deviation of these values? Round to the nearest tenth. 12, 13, 15, 4, 11, 12
Plz help
Answers
Answer:
i. Mean = 11.2
ii. Variance = 14.17
iii. Standard deviation = 3.76
Step-by-step explanation:
i. Mean, m = [tex]\frac{sum of the values}{number of the values}[/tex]
= [tex]\frac{4+11+12+12+13+15}{6}[/tex]
= [tex]\frac{67}{6}[/tex]
= 11.2
The mean of the given data is 11.2
ii. Variance = [tex]\frac{sum(x_{i} - m)^{2}}{n-1}[/tex]
where: [tex]x_{i}[/tex] is the value of the one observation, m is the sample mean and n is the number of data given.
= [tex]\frac{[(4-11.2)^{2}+(11-11.2)^{2} + (12-11.2)^{2} + (12-11.2)^{2} + (13-11.2)^{2} + (15-11.2)^{2}] }{6-1}[/tex]
= [tex]\frac{[51.84+0.04+0.64+0.64+3.24+14.44]}{5}[/tex]
= [tex]\frac{70.84}{5}[/tex]
= 14.168
Variance = 14.17
iii. Standard deviation = [tex]\sqrt{Variance}[/tex]
= [tex]\sqrt{14.17}[/tex]
= 3.76
A taxi driver charges you $1.50 for the first mile and $.90 for each additional mile. How far could you go for $20.00 if you give the driver a $2.00 tip?
Answers
Answer:
You can go 19.33 miles for $20.00 if you give the driver a $2.00 tip.
Step-by-step explanation:
From the information provided, you can say that the total cost of the taxi is equal to the cost of the first mile plus the price for each additional mile for the number of additional miles, which can be expressed as:
c=1.50+0.90(x-1), where
c is the total cost
x is the number of miles
Now, if you want to determine how far you can go for $20 if you give the driver a $2.00 tip, first you have to subtract the tip from the amount you have:
20-2=18
Then, you know that you have $18 for the cost of the taxi and you can replace c with this value and solve for x to find the number of miles:
18=1.50+0.90(x-1)
18-1.50=0.90x-0.90
16.5+0.90=0.90x
17.4=0.90x
x=17.4/0.9
x=19.33
According to this, the answer is that you can go 19.33 miles for $20.00 if you give the driver a $2.00 tip.
Answer:
You can go 19.33 mile

Step-by-step explanation:
Step 1: Cross-multiply.
9(x−4)/6=x+2/2
9(x−4)*(2)=(x+2)*(6)
18x−72=6x+12
Step 2: Subtract 6x from both sides.
18x−72−6x=6x+12−6x
12x−72=12
Step 3: Add 72 to both sides.
12x−72+72=12+72
12x=84
Step 4: Divide both sides by 12.
12x/12=84/12

Wands each fairy owns
Wands

Answers
Answer:
7
Step-by-step explanation:
each wand = 2 so you add the wands and multiply the wands by 2
then you divide the answer to the last calculation by 4
which is 28 divided by 4
which = 7
The mean of the data is 7.
What is Arithmetic Mean?The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.
Given:
Glenda = 2 x 2= 4 wands
Tink = 3 x 2= 6 wands
Merry = 4 x 2= 8 wands
Gracie = 5 x 2= 10 wands'
So, Arithmetic Mean = (Sum of wands) / (Total number of wands)
= (4+ 6 +8 + 10)/4
= 28/4
= 7
Hence, the mean is 7.
