Formula :

Answer:

[tex]\large \boxed{\sf 7n + 6}[/tex]

Explanation:

Sequence: 13, 20, 27,...

Find common difference: second term - first term = 20 - 13 = 7

As it is an explicit arithmetic term:

⇒ a + (n - 1)d             (a is the first term, d is common difference)

⇒ 13 + (n -1)(7)

⇒ 7n - 7 + 13

⇒ 7n + 6

Using the z-distribution, it is found that the 99% confidence interval to estimate Q is (74.4, 96.6). The interpretation is that we are 99% sure that the true mean for all cars rented in the city is between these two values.

The confidence interval is:

[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

The other parameters of the interval are given as follows:

[tex]\overline{x} = 85.5, \sigma = 19.3, n = 20[/tex].

Hence the bounds of the interval are given as follows:

[tex]\overline{x} - z\frac{\sigma}{\sqrt{n}} = 85.5 - 2.575\frac{19.3}{\sqrt{20}} = 74.4[/tex]

[tex]\overline{x} + z\frac{\sigma}{\sqrt{n}} = 85.5 + 2.575\frac{19.3}{\sqrt{20}} = 96.6[/tex]

The interpretation is that we are 99% sure that the true mean for all cars rented in the city is between these two values.

Answer:

Step-by-step explanation:

y = 5x² - 17x - 12

to find the roots let y = 0 , that is

5x² - 17x - 12 = 0

Factorising the quadratic

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 5 × - 12 = - 60 and sum = - 17

the factors are - 20 and + 3

use these factors to split the x- term

5x² - 20x + 3x - 12 = 0 ( factor first/second and third/fourth terms )

5x(x - 4) + 3(x - 4) = 0 ← factor out (x - 4) from each term

(x - 4)(5x + 3) = 0

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

5x + 3 = 0 ⇒ 5x = - 3 ⇒ x = - [tex]\frac{3}{5}[/tex] = - 0.6

roots are (4, 0 ) and (- 0.6, 0 )

Answer:

x = 3.255 cm

Step-by-step explanation:

Given:

⇒ y = 10cm

⇒ θ = 19

To find:

⇒ Value of "n"

Solution

⇒ By Pythagoras theorem

⇒ Δ Sin θ = n/y

⇒ sin 19° = n/10

⇒ 0.3255 = n/10

⇒ n = 0.3255 × 10

⇒ n = 3.255 cm

Hence, the answer is = n = 3.255 cm.

alrighty sooo....

when a polynomial is written in standard form that means that the exponents are in order from greatest to least.... (i hope that isn't confusing....)

here is an example:

x^6  +  x^5  + x^2 + 23     --> this polynomial is in standard form because the exponents are in order from least to greatest..... 6 then 5 then 2 then 1

(remember that a number like 23 have an invisible 1 as the exponent....

Answer:

1407.43

Step-by-step explanation:

The eqaution for surface area of a cylinder is 2πr+2π[tex]r^{2}[/tex]'

but you already got the circumference so you work backwards

16pi/pi=16

16/2=8

r=8

h=20

So you plug it into the eqaution

2π8*20+2π8^2=1407.43

The area that each color would occupy in the circular garden is: 251.32 sq. ft.

Area of a circle = πr², where the radius of the circle is represented as r.

Area of the circular garden = πr² = π(20²)

Area of the circular garden = 1,256.6 sq. ft.

Area of space each color would cover = 1,256.6/5 = 251.32 sq. ft.

Answer:

-x^4-5x^3+2x²+ 10x = (x+5)(2x-x³)

Step by Step explanation

Naming the coefficient of x² as "a" and the independent temine of the first parenthesis as "b", we got:

-x^4-5x^3+ ax^2 +10x=(x+b)(2x-x^3)

- x⁴-5x^3+ ax^2 +10x = 2x²- x⁴+2bx-bx³

-5x^3+ ax^2 +10x = -bx³+2x²+2bx

( Matching the exponents)

For x: 2b= 10; b=10/2. 

            b=5

For x²: a=2

For x³: -b=-5

             b=5
