Answer:
[tex]a_{n}[/tex] = - 5n - 2
Step-by-step explanation:
There is a common difference between consecutive terms, that is
- 12 - (- 7) = - 17 - (- 12) = - 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 5, then
[tex]a_{n}[/tex] = - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2

The value of the internal angle m from the heptagon is given by the equation m = 141°.
What is the sum of a polygon's internal angles?The formula returns the sum of the internal angles of a polygon.
The sum of the internal angles of an n-sided polygon is n = 180° (n - 2), where n is the number of sides = angle in degrees
Given the data,
Let's call the polygon a heptagon.
The polygon has n sides, which equals 7 sides.
Now, n = 180 is the sum of the interior angles of a polygon with n sides ( n - 2 )
7θ = 180 ( 7 - 2 )
7θ = 180 ( 5 )
When we simplify the equation, we obtain 7 = 900°.
A = 900° denotes the sum of the internal angles of the polygon.
And , the value of A = 120° + m° + 148° + 90° + 142° + 130° + 129°
900° = m + 759°
Subtracting 759° on both sides of the equation , we get
m = 141°
Hence , the interior angle ∠B = 141°

C n + 14
Answers
Answer:
Option E : n+70 is the correct answer.
Step-by-step explanation:
Given that:
n is divisible by 2,5 and 14.
We have to add a number to n which will make the resulting number also a divisible of 2, 5 and 14.
Therefore,
We will add a number that is multiple of 2,5 and 14
Here,
7 is not a multiple of 2,5 and 14.
20 and 10 are multiples of 2 and 5 but not 14.
70 is a multiple of 2,5 and 14.
14 is a multiple of 2 and 14 but not 5.
Hence,
Option E : n+70 is the correct answer.

A) 58.7 <h<64.9
B)59.5<h<61.8
C)59.5<h<64.1
D)61.8<h<64.1
Answers
The interval estimate of the population mean when a random sample is taken of the speed on highway is 59.5<h<64.1. Option C is correct.
What is margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
The interval estimate of the population mean can be found out using the following formula:
[tex]\overline X\pm MOE[/tex]
Here, [tex]\overline X[/tex] is the average mean, and the MOE is the margin of error.
On a highway, a random sample is taken of the speed, in mph, of 50 cars.
A mean speed is 61.8 mphThe margin of error is +2.3 The confidence interval is 95%Put the values in the above formula as,
[tex]61.8\pm 2.3\\59.5,641[/tex]
Thus, the interval estimate of the population mean
[tex]59.5 < h < 61.8[/tex]
Hence, the interval estimate of the population mean when a random sample is taken of the speed on highway is 59.5<h<64.1. Option C is correct.

What is the best estimate of the area of the figure in square inches?
Answers
To find the area of this figure the best action would to divide it into three different sections, finding the area of each and then adding them all together.
First, find the area of the square in the center, which would be 60in.
Second, find the area of the half circle. You would use the formula for area of a circle. You would divide this answer by 2 since this is only half of a circle. You would get 14.135in.
Last, you would find the area of the triangle. You would multiply both sides and then divide by 2, since it’s a triangle and not a square. Area for this is 12in.
And then you would add all these together.

86.1372 --------> 86.137 (Nearest Thousandths)
Step-by-step explanation:
Semicircle: 3.14*[tex]3^{2}[/tex]/2 = 14.1372
Triangle: 4*6 = 24/2 = 12
Rectangle: 10*6 = 60
14.1372 + 12 + 60 = 86.1372
86.1372 -------> 86.1 (Nearest Tenths)
86.1372 -------> 86.14 (Nearest Hundreths)

Answers
Answer:
$1,061.21
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Present value (PV) = $1,000
Rate of interest compounded yearly (r) = 2%
Time period (n) = 3
So, we can calculate the future value (FV) by using following formula,
Future Value = PV(1 + r)^n
By putting the value, we get
FV = $1,000 ( 1 + 0.02)^3
= $1,000 ( 1.02)^3
= $1,000 ( 1.061208)
= $1,061.21

Find the value of x and y
I don’t know how
Answers
Answer:
x = 2√30, y = 2√21
Step-by-step explanation:
You can create the following equations:
(1) from the left triangle with sides x, y and 6:
y² + 6² = x²
(2) from the right triangle with sides y, 14 and... lets call it z:
y² + 14² = z²
(3) from the big triangle:
x² + z² = 20²
(4) Combine (2) and (3) to eliminate z:
x² + y² + 14² = 20²
combine (1) and (4) to eliminate x:
y² + 6² + y² + 14² = 20²
simplify
2y² = 20² - 6² - 14² = 168
y² = 84
y = √84 = 2√21
x² = y² + 6² = 84 + 36 = 120
x = √120 = 2√30
