Two numbers are in the ratio 5:2 and their sum is 56. Find the numbers. Please plain how to do this

Answer:

aₙ = a₁ - 6* (n-1)

Step-by-step explanation:

a₁ = 13 = 13 - 6* (1-1)

a₂ = 7 = 13 - 6 * 1 = 13- 6*(2-1)

a₃ = 1 = 7 - 1 = 13 - 6 * 2 = 13 - 6 * (3-1)

........

aₙ = a₁ - 6* (n-1)

check: a₅ = 13 - 6*4 = -11

Step-by-step explanation:

phil has 3 tables with 21 balloons on each

D would be the answer to solve 3x7=21. A is adding 21 with 3 and B is multiplying 3 and 21 witch isn’t what we’re looking for. Then for C, it would be subtracting 22 by 3. D is the only one witch said that Phil has 21 balloons and he put the same number of ballon on 3 tables. This way they can divide 21 with 3 and gives the quotient of 7. So D would be the best answer t solve he problem 3x7=21.

answer:f60 and 40

Step-by-step explanation:

a line is a 180 degree angle there's 80 already there and then 60 plus 40 is a hundred

x=20

3 times 20 equals 60

2 times 20 equals 40

60+40+80= 180

Jane is 19 9/20 years old. If Marian is 11/2 years bigger then Mark, you would have to add both ages up and then get the answer of 17 1/4. Then it said that Jane is 11/5 years older than Marian which means that you would have to add again to find the final answer. 11/5=2 1/5 and then add 17 1/4 which you get 19 9/20. So Jane is 19 9/20 years old.

Answer:

22/3 years old jane

Step-by-step explanation:

add 11+11 =22

2+5=7

7-3=4

so, she's 22/3 years old

The outliers of the given data seta are -

- 0.5 and 23.5

An outlier is an observation that lies an abnormal distance from other values in a random sample from a population.

Given is a dataset shown in the image.

Arrange the data in ascending order -

(6, 7, 8, 8, 9, 10, 10, 11, 12, 13, 13, 14, 15, 15, 15, 40)

(x₁, x₂, x₃, x₄, x₅, x₆, x₇, x₈, x₉, x₁₀, x₁₁, x₁₂, x₁₃, x₁₄, x₁₅, x₁₆)

First quartile -

Q{1} = (x₅ + x₄)/2 = (9 + 8)/2 = 8.5

Q{1} = 8.5

Third quartile -

Q{3} = (x₁₂ + x₁₃)/2 = (14 + 15)/2 = 14.5

Q{3} = 14.5

Interquartile range -

IQR = Q{3} - Q{1}

IQR = 14.5 - 8.5

IQR = 6

Outliers -

(numbers less than Q1 – 1.5 × IQR) = - 0.5

(numbers greater than Q3 + 1.5 × IQR) = 23.5

Therefore, the outliers of the given data seta are -

- 0.5 and 23.5

Answer:

0.4785

Step-by-step explanation:

Answer:

287.5 years

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

t = (1/0.04)((750/60) - 1) = 287.5

t = 287.5 years

Step-by-step explanation:

according to the question

3x-1=0

3x=1

x=⅓

so

f(x)=18x³+x-1

f(⅓)=18.(⅓)³+⅓-1

f(⅓)=18.⅓.⅓.⅓+⅓-1

f(⅓)=6.⅑+⅓-1

f(⅓)=⅔+½-1

f(⅓)=0

percent error=6%

Step-by-step explanation:

Step one:

given data

Patty counted 250

The actual amount of chocolate chips on the tray were 265

Required

The percent error

Step two:

The formula is

percent error= actual-expected/expected*100

percent error= 265-250/250*100

percent error=15/250*100

percent error=0.06*100

percent error=6%

Answer:

12.50/100 X 110 = 13.75

13.75-12.50 = 1.25

12.50/100 X 109 = 13.625

13.625 + 1.25 = 14.875

Step-by-step explanation:

Since -5, -3 and 1 are the zeroes of f(x),

(x + 5), (x + 3) and (x - 1) are factors of f(x).

=> f(x) = a(x + 5)(x + 3)(x - 1),

where a is a real constant.

We are given that when x = 0, f(x) = -45.

=> a(0 + 5)(0 + 3)(0 - 1) = -45

=> -15a = -45, a = 3.

Hence, f(x) = 3(x + 5)(x + 3)(x - 1)

= 3x³ + 21x² + 21x - 45.

Answer:

The function f(x) is a cubic function and the zeros of f(x) are -5, -3 and 1. The y-intercept of f(x) is -45.

(x+5), (x+3) and (x-1) are the factors of f(x).

Form : f(x)=a(x+5)(x+3)(x-1)

When f(x)=-45 and x=0, we get a=3

Equation of the cubic polynomial in standard form is :---

[tex]f(x) = 3(x + 5)(x + 3)(x - 1)\\ =3 ( {x}^{2} + 8x + 15)(x - 1) \\=3({x}^{3} + 8 {x}^{2} + 15x - {x}^{2} - 8x - 15) \\ =3({x}^{3} + 7{x}^{2} + 7x - 15)\\=\boxed{3{x}^{3}+21{x}^{2}+21x-45}[/tex]
