what is 1/10 as a percentage
Answer:
10% or .10
Step-by-step explanation:
-5x+3y=15 and 2x-3y= -15
Answer:
x = 0; y = 5
Step-by-step explanation:
-5x + 3y = 15
2x - 3y = -15
Add the equations to eliminate y.
3x = 0
x = 0
Now plug in 0 for x in the first equation to solve for y.
-5(0) + 3y = 15
3y = 15
y = 5
Answer: x = 0; y = 5
Solve for x.
x² = 9
x=±3
x=±4.5
x=±18
x=±81

Answer:
x = 7.5
Step-by-step explanation:
Since the midsegment and the third segment of the triangle are parallel to each other, therefore,
[tex] \frac{8 + 10}{8} = \frac{6 + x}{6} [/tex]
[tex] \frac{18}{8} = \frac{6 + x}{6} [/tex]
[tex] \frac{9}{4} = \frac{6 + x}{6} [/tex]
Cross multiply
[tex] 9*6 = 4(6 + x) [/tex]
[tex] 54 = 24 + 4x [/tex]
Subtract 24 from each side
54 - 24 = 4x
30 = 4x
Divide both sides by 4
30/4 = x
7.5 = x
x = 7.5

The ground temperature at airport is 12 degrees. The temperature decreases by 5.2 degrees for every mile above ground. What would be temperature outside plane located at 3 miles above the airport
Answer:
The outside plane located at 3 miles above the airport is of -3.6 degrees.
Step-by-step explanation:
The ground temperature at airport is 12 degrees. The temperature decreases by 5.2 degrees for every mile above ground.
This means that the temperature in n miles above ground is given by:
[tex]T(n) = 12 - 5.2n[/tex]
What would be temperature outside plane located at 3 miles above the airport
This is T(3). So
[tex]T(3) = 12 - 5.2*3 = 12 - 15.6 = -3.6[/tex]
The outside plane located at 3 miles above the airport is of -3.6 degrees.

which eams more?
9514 1404 393
Answer:
10,247.38 from continuous compounding10,228.50 from semiannual compoundingcontinuous compounding earns moreStep-by-step explanation:
The formula for the account balance from continuously compounded interest at annual rate r for t years is ...
A = Pe^(rt) . . . . P = principal invested
A = 8820e^(0.05·3) ≈ 10,247.38 . . . continuous compounding
__
The formula for the account balance from interest compounded semiannually at annual rate r for t years is ...
A = P(1 +r/2)^(2t)
A = 8820(1 +.05/2)^(2·3) ≈ 10,228.50 . . . semiannual compounding
Continuous compounding earns more.

Answer:
10017
Step-by-step explanation:
10^(4)-\sqrt(121)+3^(3)+4^(0)
So, 3^3= 27
4^0=1
10^4=10,000
-square 121= -11
So now you got:
10,000-11+27+1
=10017
Answer:
910
Step-by-step explanation:
1000-121 =879
879 + 27+ 906
906 + 4 = 910
The triangle below is reflected over the line x = 4.
Which transformation(s) would produce the same image?
2676$10
A Reflecting over the x-axis and then translating to the right 4 units
B. Reflecting over the y-axis and then translating to the right 4 units
C Reflecting over the y-axis and then translating to the right 8 units
D Reflecting over the x-axis and then translating to the right 8 units
9514 1404 393
Answer:
C. Reflecting over the y-axis and then translating to the right 8 units
Step-by-step explanation:
Reflection over the line x=4 gives you the transformation ...
(x, y) ⇒ (2·4 -x, y) = (-x +8, y)
This is precisely the same transformation you get by reflection over the y-axis:
(x, y) ⇒ (-x, y)
followed by translation to the right 8 units:
(-x, y) ⇒ (-x +8, y)
__
Reflection over x=4 is the same as reflection over y and translation right 8.

Step-by-step explanation:
A political scientist wants to estimate the percent of registered voters in Florida who plan to vote for a particular candidate. The political scientist interviews 4000 randomly selected registered voters in Florida and asks who they plan to vote for. 58% say they plan to vote for the candidate. Which of the following statements is true?
a. 58% is a parameter because it describes a population characteristic.
b. 58% is a statistic because it describes a sample characteristic.
c. 58% is a statistic because it describes a population characteristic.
d. 58% is a parameter because it describes a samic characteristic.
Answer:
b.) 58% is a statistic because it describes a sample characteristic.
Step-by-step explanation:
The randomly selected 4000 voters represents a randomly selected observations from the population of registered voters
Hence, 4000 is a sample.
The percentage of voters who would vote for a particular candidate represents a numerical characteristic derived from the sample drawn.
Recall that, numerical characteristics or values which are calculated from the sample is known as statistic while those derived from the population are called parameter.
Hence, 58% is a statistic as it describes a sample characteristic.
You can use definition of parameter and statistic and then can use them to find what does 58% denotes here.
The true statement is given by:
Option B: 58% is a statistic because it describes a sample characteristic.
What is a population and parameter?The entire group or system which we are taking in consideration is population. Nothing bigger than it lies there in consideration.
Ex: If we're taking about health problem in a country, then the whole country people form a population.
If we're taking about numbers on a 6 face die, then those 6 numbers on 6 faces form a population.
Those numbers who summarize information about population are called parameter.
What is sample and statistic?A portion of population taken and analyzed to predict information about population is called sample of that population.
Ex: When someone surveys a group, then he/she surveys a portion and not whole population in general.
Those numbers who summarize information about sample are called statistic.
(Statistic is different than statistics)
Using above definitions to conclude what 58% refers toSince the 58% is from the 4000 people randomly selected by the political scientist, thus, it is information about sample and thus, is a statistic.
Thus,
The true statement is given by:
Option B: 58% is a statistic because it describes a sample characteristic.

Answer:
[tex]x=2.3\text{ only }[/tex]
Step-by-step explanation:
We are given the second derivative:
[tex]g^\prime^\prime(x)=0.1x^5-0.29x^4-0.694x^3+1.9136x^2[/tex]
And we want to find the values for -3 < x < 4 in which the graph of g has a point of inflection where the concavity changes from concave up to down.
First, recall that inflection points occur whenever g''(x) = 0 or is undefined.
And that:
g is concave up for an interval if g''(x) > 0 for that interval. g is concave down for an interval if g''(x) < 0 for that interval.Graphing the function (please refer below for the graph), we can see that g''(x) has an inflection point at x = -2.6, 0, 2.3, and 3.2.
If g''(x) changes from concave up to concave down, the values before and after that inflection point must be positive and then negative.
We can see that g''(x) is only positive for the values before the inflection points at x = 0 and x = 2.3.
However, for values after the inflection points, only x = 2.3 becomes negative.
Therefore, since at x = 2.3, the graph changes from positive to negative, this is where the graph of g changes from concave up to concave down.
Notes:
For the point x = 0, the graph stayed positive both before and after x = 0.
Therefore, g does not have an inflection point at x = 0.
