These data show the ring size for a sample of 8 men 12 10 11.5,11.5, 12, 9, 9 , 11 what is the best approximation of the standard deviation of the ring size data
Answers
mean is (12+10+11.5+11.5+12+9+9+11)/8
thus, mean = 10.75
Sample standard, s= √(∑(x-m)²)/(n-1)
= 1.172
I therefore, believe that the best approximation of standard deviation is 1.17
Answer:
Standard deviation of ring size is 1.253
Step-by-step explanation:
We are given the following data-set:
12, 10, 11.5, 11.5, 12, 9, 9, 11
n = 8
Formula:
[tex]\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}[/tex]
where [tex]x_i[/tex] are data points, [tex]\bar{x}[/tex] is the mean and n is the number of observations.
[tex]Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}[/tex]
[tex]Mean =\displaystyle\frac{86}{8} = 10.75[/tex]
Sum of squares of differences = 1.5625 + 0.5625 + 0.5625 + 0.5625 + 1.5625 + 3.0625 + 3.0625 + 0.0625 = 11
[tex]S.D = \sqrt{\displaystyle\frac{11}{7}} = 1.253[/tex]

wombat has 4 feet and 1 head
E = emu
W = Wombat
E +W = 52
2E +4W = 148
E = 52-W
2(52-W) + 4W = 148
104-2W +4W = 148

Starting at home, Jessica traveled uphill to the toy store for 12 minutes at just 10 mph. She then traveled back home along the same path downhill at a speed of 30 mph. What is her average speed for the entire trip from home to the toy store and back?
Answers
Answer: 15 mph
Step-by-step explanation:
Given: Time taken to travel uphill to the toy store= 12 minutes[tex]=\frac{12}{60}=0.2\ hour[/tex]
Let d be the distance(in miles) between the home and toy store.
Also, [tex]Speed=\frac{Distance}{Time}[/tex]
[tex]\\\Rightarrow10=\frac{d}{0.2}\\\Rightarrow\ d=0.2\times10=2[/tex]
Thus, distance from home to toy store= 2 miles
When she turn back, to home distance remains same.
The time taken by her to come back at 30 mph speed=
[tex]Time=\frac{Distance}{speed}=\frac{2}{30}=\ hour[/tex]
Now, the average speed =[tex]\frac{\text{Total distance}}{\text{Total time}}[/tex]
[tex]=\frac{2+2}{0.2+\frac{2}{30}}\\=\frac{4}{\frac{6+2}{30}}\\=\frac{4\times30}{8}=\frac{120}{8}=15\ mph[/tex]

What are the zeroes of the function? What are their multiplicities?
= x4 – 4x3 + 3x2 (1 point)
Answers
You can simplify the terms as so:
x^2(x^2-4x+3) = 0
The equation above now contains x^2 and a quadratic function. A potential solution is x = 0 because x^2 = (0)^2 = 0.
Regarding the quadratic part of the equation,
x^2 - 4x + 3 = 0
(x+4)(x-1) = 0
When x = -4 or 1, the entire equation equals zero.
Therefore, the zeroes of the function are -4, 0, and 1.
What is the solution to the equation 5x + 2y = -9

c.(-2,5)
d.(1,-3)
Answers
In order to find which one of the given points is a solution to the equation, we need to plug each point in the equation and check which one fits in .
The equation is :
5x+2y=-9
a.(2,-4)
5x+2y=-9
LHS: 5x+2y
Plugging (2,-4) in this,
5(2) +2(-4) = 10-8 =2
RHS : -9
LHS ≠RHS
So (2,-4) is not the solution.
b.(-1,2)
5x+2y=-9
LHS: 5x+2y
Plugging (-1,2) in this,
5(-1) +2(2) = -5+4 =-1
RHS : -9
LHS ≠RHS
So (-1,2) is not the solution.
c.(-2,5)
5x+2y=-9
LHS: 5x+2y
Plugging (-2,5) in this,
5(-2) +2(5) = -10+10 =0
RHS : -9
LHS ≠RHS
So (-2,5) is not the solution.
d.(1,-3)
5x+2y=-9
LHS: 5x+2y
Plugging (1,-3) in this,
5(1) +2(-3) = 5-6=-1
RHS : -9
LHS ≠RHS
So (1,-3) is not the solution.

Answers
(.45 × 150) + 20 = 87.5
Answer:
E.The price for travelling 150 miles is same for both company.
Step-by-step explanation:
We are given that Joseph is going on a trip and he needs to rent a car.
Company A
Charge $0.25 per mile plus $50 rental fee.
Company B charges 40.45 per mile plus $20 rental fee.
A.Total distance=150 miles
Company A
Charges for 150 miles=[tex]150\times 0.25=[/tex]$37.5
Total charges=37.5+50=$87.5
Company B
Charges for 150 miles=[tex]150\times 0.45[/tex]=$67.5
Total charge=20+67.5=$87.5
The price for travelling 150 miles is same for both company.
But if distance greater than 150 miles such 155 miles
Company A
Total charge=[tex]155\times 0.25+50=[/tex]$88.75
Company B
Total charges=[tex]155\times 0.45+20=[/tex]$89.75
Company A is better deal if Joseph more than 150 miles.
If distance 145 miles
Price form company A=[tex]145\times 0.25+50=[/tex]$86.25
Price form company B=[tex]145\times 0.45+20=[/tex]$85.25
Company B is better deal if Joseph travel less than 150 miles.
Hence, option E is true.

the thickness of a deep dish pizza is approximately 2 x 10^-1 feet. the thickness of a thin crust pizza is approximately 5 x 10^-2 feet. how many times smaller is the thickness of a thin crust pizza compared to the thickness of a deep dish pizza?
A. 0.25
B.0.4
C4
D25
Answers
The thickness of the thin crust can be evaluated in a similar way. [tex]10^-^2=0.01[/tex]. 5(0.01) = 0.05 ft for the thin crust pizza.
We don't know how many times bigger the deep dish is, so that is our variable. That gives us:
[tex]0.05x=0.2[/tex] (the thickness of the thin crust multiplied by an unknown factor equals the deep dish)
Divide both sides by 0.05:[tex]\frac {0.05x}{0.05}= \frac{0.2}{0.05} \\ x=4[/tex]
The deep dish is 4 times bigger than the thin crust, which means the thin crust is 4 times smaller than the deep dish.
The thickness of a thin crust pizza is 4 times smaller than the thickness of a deep dish pizza.
The question asks us to compare the thickness of a deep dish pizza to that of a thin crust pizza and determine how many times smaller the thin crust is. The deep dish pizza has a thickness of 2 x 10⁻¹ feet and the thin crust pizza has a thickness of 5 x 10⁻² feet. To find how many times smaller the thin crust is, we divide the thickness of the thin crust by the thickness of the deep dish pizza:
(5 x 10⁻² feet) / (2 x 10⁻¹ feet) = 0.25
A scientist wants to measure out 0.62 liters of a liquid, but she can only find a beaker that measures volume in milliliters. How many milliliters should she measure to equal 0.62 liters?
Answers
0.62 liters=620ml
To convert 0.62 liters to milliliters, you multiply 0.62 by 1,000, which equals 620 milliliters. Therefore, the scientist should measure out 620 milliliters of the liquid.
Explanation:When a scientist wants to measure out 0.62 liters of a liquid, but only has a beaker that measures volume in milliliters, she needs to first understand the conversion between liters and milliliters. 1 liter is equal to 1,000 milliliters. So, she would need to convert 0.62 liters to milliliters. She can do this by multiplying 0.62 liters by 1,000. This gives her 620 milliliters. Therefore, if a scientist wants to measure out 0.62 liters of a liquid, but the beaker only measures volume in milliliters, then she should measure out 620 milliliters.

At 9:00 on Saturday morning, two bicyclists heading in opposite directions pass each other on a bicycle path. The bicyclist heading north is riding 5 km/hour faster than the bicyclist heading south. At 10:45, they are 47.25 km apart. Find the two bicyclists’ rates.
Answers
A = r(1.75)
A = 1.75r
(47.25 - A) = (r + 5)(1.75)
47.25 - A = 1.75r + 8.75
47.25 - A - 8.75 = 1.75r
38.5 - A = 1.75r
38.5 - A = A
38.5 = 2A
19.25 = A
So A has traveled 19.25 km in 1.75 hours; this gives him a speed of 11 km/h. Bicyclist B has, therefore, traveled 47.25 km - 19.25 km = 28 km in 1.75 hours, giving him a rate of 16 km/h, which fits the provided information.

If 543 planes leave from JFK airport and each plane has 228 passengers, how many people have flown out of JFK? people;
Answers
123,804 people have flown out of JF-K airport based on the assumption of full plane occupancy. Real-world variations and logistical complexities may impact the actual number.
To find the total number of people who have flown out of JF-K, you can multiply the number of planes by the number of passengers per plane.
543 planes * 228 passengers/plane = 123,804 people
Therefore, 123,804 people have flown out of JF-K airport.
It's important to note that this calculation assumes each plane is fully occupied and that there are no variations in passenger counts.
In reality, the number of passengers on each plane may vary, and factors such as seat availability, ticket sales, and other considerations can affect the actual number of people who have flown out of JF-K. Additionally, this calculation does not account for return flights, layovers, or other complexities in air travel logistics.

The second choice is the correct one
Explanation:
(2x+3)^2 + 8(2x+3) + 11 = 0
To use the u substitution, we will assume that:
2x + 3 = u
Substitute with this in the given expression, we will get:
u^2 + 8u + 11 = 0
The general form of the second degree equation is:
ax^2 + bx + c = 0
Comparing the expression we reached with the general one, we will find that:
a = 1
b = 8
c = 11
The roots can be found using the rule found in the attached picture.
This means that, for the given expression:
u = -4 ± √5
Now, we have:
u = 2x+3
This means that:
at u = -4 + √5
2x + 3 = -4 + √5
2x = -7 + √5
x = (-7 + √5) / 2
at u = -4 - √5
2x + 3 = -4 - √5
2x = -7 - √5
x = (-7 - √5) / 2
This means that, for the given expression:
x = (-7 ± √5 ) / 2
Hope this helps :)
Using substitution we have:
u = 2x + 3
We rewrite:
(u) ^ 2 + 8 (u) + 11 = 0
We use resolvent:
u = (- b +/- root (b ^ 2 - 4ac)) / (2a)
We replace:
u = (- (8) +/- root ((8) ^ 2 - 4 (1) (11))) / (2 (1))
u = (- (8) +/- root (64 - 44)) / (2)
u = (- (8) +/- root (20)) / (2)
u = (- (4) +/- root (5))
We return the change:
u = (- (4) +/- root (5)) = 2x + 3
We clear x:
x = (- (7) +/- root (5)) / 2
Answer:
x = (- (7) +/- root (5)) / 2
