The approximation in meters that is same with a notebook paper measures 8 1/2 inches by 11 inches is
c. 22 cm x 28 cmHow to determine approximationsThe approximation is solved by converting the given unit to metric
The conversion from inches to metric
meters = m
inches = in
The unit conversion factor is given as
1 meter = 39.3701 inches
? meter = 8 1/2 inches
cross multiplying gives
? * 39.3701 = 1 * 8 1/2
? = 8 1/2 / 39.3701
? = 0.2159 m
? = 21.59 cm
? =22
11 inches to metric
? = 11 / 39.3701
? = 27.94 cm
? = 28

a hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.6 pounds. a sample of seven infants is randomly selected and their weights at birth are recorded as 9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6 pounds. what is the sample variance? multiple choice 1.177 6.6 1.386 7.6
1.386 is the sample variance .
What does the standard deviation of the sample mean?
The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean.Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.Step 1:Add them up:
9.0 + 7.3 + 6.0 + 8.8 + 6.8 + 8.4 + 6.6 = 52.9
Step 2: Square your answer:
52.9 × 52.9 = 2798.41
…and divide by the number of items. We have 7 items in our example so:
2798.41 / 7 = 399.773
Set this number aside for a moment.
Step 3: Take your set of original numbers from Step 1, and square them individually this time:
9.0^2 + 7.3^2 + 6.0^2 + 8.8^2 + 6.8^2 + 8.4^2 + 6.6^2 = 408.09
Step 4: Subtract the amount in Step 2 from the amount in Step 3.
408.09 - 399.773 = 8.317
Set this number aside for a moment.
Step 5: Subtract 1 from the number of items in your data set. For our example:
7 – 1 = 6
Step 6: Divide the number in Step 4 by the number in.
This gives you the variance:
8.317/ 6 = 1.386

Desmos graphing calculator is a life saver for questions like this
Answer:
option 3
Step-by-step explanation:
2x + 5y = 20
to bring this to a staffers equation with y on one side and everything else on the other, we see that we get a negative x term. that means the line goes down when going from left to right.
5y = -2x + 20
y = -2/5 x + 4
so, we also see that the y-intercept is 4.
so, option 3 is correct.

a manufacturer of headache medicine claims it is 70% effective within a few minutes. that is, out of every 100 users, 70 get relief within a few minutes. a group of 12 patients are given the medicine. if the claim is true, what is the probability that eight have relief within a few minutes?
0.231140 is the probability that eight have relief within a few minutes .
What is probability explain with an example?
It is based on the probabilities that something could happen. The logic underpinning probability serves as the foundation for theoretical probability. A coin is tossed, for instance, and the theoretical likelihood of getting a head is 1 in 2.let X be the number of patients having relief within a few minutes out of 12 patients.
so X~ Bin(12,p) where p=0.70
so P[8 have relief within a few minutes]=P[X=8]

The least common denominator for the rational expression is (x + 8) (x + 2) (x - 1)
What is LCD in Rational Expression ?
The denominators' smallest common multiple is called the LCD. We factor the expressions and multiply each unique factor to obtain the LCD of two rational expressions.
The given expression is,
(x + 2) / (x² + 7x - 8) , (x - 6) / (x² +10x + 16)
Let,
(x + 2) / (x² + 7x - 8) --------eq(i)
(x - 6) / (x² +10x + 16) ----------- eq(ii)
First take the denominator of eq(i)
The denominator is = x² + 7x - 8
We know, this is quadratic equation so just solve this equation
⇒ x² + 8x - x - 8
⇒ x(x + 8) - 1(x + 8)
⇒ (x - 1) (x + 8)
Next, take the denominator of eq(ii)
The denominator is = x² + 10x + 16
And, this is also a quadratic equation so the factors are,
⇒ x² + 8x + 2x + 16
⇒ x(x + 8) + 2(x + 8)
⇒ (x + 2) (x + 8)
So, after solving both the denominators we get the factors ,
(x - 1) (x + 8) and (x + 2) (x + 8)
As, we see (x + 8) is common just write it once and else terms write as it is,
LCD = (x + 8) (x - 1) (x + 2)
Therefore, the least common denominator for the rational expression is (x + 8) (x + 2) (x - 1)

For the given rectangle, the area for given rectangle is 257 1/4 in. and length of a rectangle is 10 1/2 in. then its width is given by 24 1/2 in.
As given in the question,
For the given rectangle,
Area of a given rectangle is equal to 257 1/4 in.
length of a given rectangle is 10 1/2 in.
Let w be the width of a rectangle we have,
Area of a rectangle = length × width
257 1/4 = 10 1/2 × w
Convert mixed fraction into proper fraction we get,
(1029 /4) = (21/2) × w
⇒ w = (1029 ×2) / (21 × 4)
⇒ w = 49 /2
⇒ w = 24 1/2 in.
Therefore, for the given rectangle, the area for given rectangle is 257 1/4 in. and length of a rectangle is 10 1/2 in. then its width is given by 24 1/2 in.

Answer:
8/x^3
Step-by-step explanation:
(2x^-1)^3
First, we must use the power-to-power rule to eliminate the double exponents. When a power is raised to a power, we must multiply them. This makes the exponent of x-3 and makes two into 8.
8x^-3
We can eliminate negative exponents by bringing their subject to the opposite side of the fraction line, so in this case, we bring down the x^-3 to the bottom, making it x^3. The final answer is:

An a recent year, person A and person B had the two top-grossing concert tours, together generating about $314 million in ticket sales. If person B took in $28 million less than person A, how much did each tour generate?
The amount generated by person A's tour is $___ million, and the amount generated by person B's tour is $___ million.
Taking into account the definition of a system of linear equations, the amount generated by person A's tour is $171 million, and the amount generated by person B's tour is $143 million.
System of linear equationsA system of linear equations is a set of linear equations that have more than one unknown, related by the aforementioned equations and whose objective is to find out their values.
Then, solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.
This caseIn this case, a system of linear equations must be proposed taking into account that:
"A" is the amount generated by person A's tour."B" is the amount generated by person B's tour.You know:
Person A and person B had the two top-grossing concert tours, together generating about $314 million in ticket sales. Person B took in $28 million less than person A.The system of equations to be solved is
A + B= 314 million
B= A - 28 million
From the several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, substituting the second equation in the first one you get:
A + A - 28 million= 314 million
Solving:
A + A= 314 million + 28 million
2A= 342 million
A= 342 million÷ 2
A= 171 million
Substituting this value in the second equation:
B= A - 28 million
B= 171 million - 28 million
B= 143 million
Finally, the amount generated by person A's tour and B's tour is $171 million and $143 million respectively.

plans. Plan A would cost $480 for one year.
Plan B would cost $250 for 6 months.
Tammy reasons that plan B must cost more
for one year. Is there enough information to
know if she is correct? Explain your
reasoning.
Answer:
Theusage is 585 minutes of call duration..
Explanation:
Fixed plan cost is M=$.39.95
Charge for first 500 minutes call: Free
Charge for call exceeding 500 minutes: $.0.35/minutes.
Let x minutes be the total call duration.
The bill is P=$.69.70 i.e. more than $.39.95, which indicates
call duration is more than 500 minutes.
The rule states that bill for call exceeding 500 minutes is
P=M+(x−500).0.35 or
69.70=39.95+(x−500).0.35 or (x−500).0.35=69.70−39.95 or
(x−500).0.35=29.75 or (x−500)=
0.35
29.75
or
(x−500)=85 or x=500+85=585 minutes.
The usage is 585 minutes of call duration .
