Answer:
I believe this would be the correct answer. It has been a while since I have done a problem like this.
Answer:
x=1 & y=7
Step-by-step explanation:
y=7x.......(i)
y=-2x+9........(ii)
Solve for (ii) by replacing the value of y in (ii) with the value of y from (i)
y=-2x+9
7x=-2x+9
Add 2x on both sides,
7x+2x=-2x+9+2x
9x=9
Divide by 9 on both sides,
9x/9=9/9
x=1
Now,
Replace the value of x in eq (i)
y=7x
y=7×1
y=7
Therefore,the values of x and y are 1 and 7 respectively.

Step-by-step explanation:
Let's go over the definition of each term.
Mean: Average of all the data. Find by adding all the terms, then dividing that by the amount of terms
Median: Value in the middle of the data when the values are in order. Find by locating the term in the middle position.
Mode: The number or numbers that occur most often in the data.
Range: Difference between the highest and lowest values in the data. Find by subtracting the lowest value from the highest.
Outlier: A number or numbers that are different from the rest of teh data and cannot be accurately included.
Now, let's find the answers.
32 + 25 + 21 + 32 + 7 + 26 + 32 + 35 + 37 + 36 + 25 + 25 + 62 + 36 = 431
431/14 = 30.8. Therefore, the mean is 30.8.
When the numbers are in order, they look like this:
7, 21, 25, 25, 25, 26, 32, 32, 32, 35, 36, 36, 37, 62.
Since there are two numbers in the middle, 32 and 32, find the average of the two numbers. 32 + 32 / 2 = 32. Therefore, the median is 32.
The numbers that occur most often are 25 and 32, which each occur three times. Therefore, the modes are 25 and 32.
The largest value is 62 and the smallest is 7. 62 - 7 = 55. Therefore, the range is 55.
There are two numbers that are much higher or much lower than the rest of the data: 7 and 62. Therefore, the outliers are 7 and 62 (hint: if you're sure there are outliers, check the highest and lowest numbers in the data).

Find the 66th term in the following
arithmetic sequence :
--92, -85, -78, -71, ...
Answer:
363
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 92 and d = - 85 - (- 92) = - 85 + 92 = 7 , thus
[tex]a_{66}[/tex] = - 92 + (65 × 7) = - 92 + 455 = 363
Answer:
363.
Step-by-step explanation:
We see that each term increases by 7.
This is an arithmetic sequence with first term (a1) = -92 and the common difference (d) is 7.
an = a1 + (n - 1)d
a66 = -92 + (66 - 1)7
= -92 + 455
= 363.

Find the 14th term of the geometric sequence 1 , − 5 , 25 , . . .
Answer:
-1220703125
Explanation:
The 14th term of the geometric sequence 1 , − 5 , 25 , . . . is (5)¹⁴ after using the geometric sequence formula.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
It is given that:
The sequence is:
1 , − 5 , 25 , . . .
The above sequence represents a geometric sequence.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity,
approaching either infinity or -infinity.
The common ratio = -5/1 = -5
The nth term a(n) = arⁿ⁻¹
The first term a = 1
The nth term a(n) = (5)ⁿ⁻¹
Plug n = 14
The 14th term a(14) = (-5)¹⁵⁻¹
The 14th term a(14) = (5)¹⁴
Thus, the 14th term of the geometric sequence 1 , − 5 , 25 , . . . is (5)¹⁴ after using the geometric sequence formula.

If $125 is invested at an interest rate of 18% per year and is compounded continuously, how much will the investment be worth in 2 years?
Use the continuous compound interest formula A = Per
$123
Answer:
$174.05
Step-by-step explanation:
To find the value of the investment at a later date:
[tex]x * multiplier^n = y[/tex]
Here, [tex]x[/tex] is the original amount, [tex]n[/tex] is the number of times the amount compounds and [tex]y[/tex] is the new value.
Let's find the multiplier. Imagine the $125 to be 100%, because that is the full amount of the investment. If you add 18% onto 100%, the result is 118%.
To convert this into a multiplier, you simply divide by 100:
118 ÷ 100 = 1.18
The original amount [tex]x[/tex] in this case is equal to $125, so we can easily substitute that into the equation. We know our multiplier is 1.18. And here, the investment is compounded once per year, and this is over a two year period, meaning the original amount will be compounded twice overall. Therefore, [tex]n=2[/tex].
Finally, we substitute our values into the equation:
[tex]125 * 1.18^2 =174.05[/tex]
This means our final answer is $174.05.

Answer:
9.4 = x
Step-by-step explanation:
You are given the hypotenuse and the adjacent side, leading you to use cosine.
Set it up:
[tex]cos48 = \frac{x}{14}[/tex]
Multiply everything by 14, to remove it from the denominator:
[tex]14(cos48 = \frac{x}{14})[/tex]
[tex]14cos48=x[/tex]
Multiply accordingly:
9.36 = x
Round to nearest tenth:
9.4 = x
