Answers

Answer:

0.512 ; - 0.538

Step-by-step explanation:

Using the standard linear regression relation :

y = bx + c

b slope ; c = intercept ; y = dependent ; x = independent variable.

For finalist between 2004 - 2014 ;

y = 0.024x - 0.328

x = 35

y = 0.024(35) - 0.328

y = 0.512

For finalist between 1990 - 2014 ; with 14 winners ; change in daily circulation :

y = -0.015x - 0.328

x = 14.

y = -0.015(14) - 0.328

y = - 0.538

There are 10 bags of cereal in a pantry. Each serving of cereal is 1/8 of a bag.

How many servings of cereal are there in the bags in the pantry?

Answers

Answer:

80 servings

Step-by-step explanation:

there is 8 serving per bag

Answer:

80

Step-by-step explanation:

Let servings be s and the bag be b

s = 1/8 b

multiply both sides by 8

8s = b

For 10 bags, it will be 10*8s = 80s which is 80 servings.

the sum of two numbers is 8. the sum of the squares of the same two numbers is 40. what are the numbers?​

Answers

Answer:

The numbers are 6 and 2

Step-by-step explanation:

Given this scenario, we can set up the following equations:

x + y = 8

x² + y² = 40.

___________

x + y = 8

y = 8 – x

(y)² = (8 – x)²

y² = (8 – x)²

x² + y² = 40

x² + (8 – x)² = 40

x² + 64 – 16x + x² = 40

2x² – 16x + 64 = 40

2x² – 16x = -24

2(x² – 8x) = -24

x² – 8x = -12

x² – 8x + 12 = 0

(x – 6)(x – 2) = 0

x = 6 or 2.

x + y = 8 →

(6 or 2) + y = 8

y = 8 – (6 or 2)

y = 2 or 6.

___________

x + y = 8 →

6 + 2 = 8 →

8 = 8 ✓

x² + y² = 40 →

6² + 2² →

36 + 4 = 40 →

40 = 40 ✓

Answer:

Step-by-step explanation:

The value of the expression A, B, C, and D will be 1, ∞, ∞, and 1.

What is Algebra?

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

You can approximate e by substituting large values for n into the expression.

Let the infinity be the largest number.

A. (1 – 1/n)ⁿ

Substitute n = ∞, then the value of the expression will be

[tex]\Rightarrow \left (1 - \dfrac{1}{\infty} \right)^{\infty}\\\\\Rightarrow \left (1 - 0 \right)^{\infty}\\\\\Rightarrow 1[/tex]

B. (1 + n)ⁿ

Substitute n = ∞, then the value of the expression will be

[tex]\Rightarrow \left (1 + \infty \right)^{\infty}\\\\\Rightarrow \infty^{\infty} \\\\\Rightarrow \infty[/tex]

C. (1 – n)ⁿ

Substitute n = ∞, then the value of the expression will be

[tex]\Rightarrow \left (1 - \infty \right)^{\infty}\\\\\Rightarrow \infty^{\infty} \\\\\Rightarrow \infty[/tex]

D. (1 + 1/n)²

Substitute n = ∞, then the value of the expression will be

⇒ (1 + 1/∞)²

⇒ (1 + 0)²

⇒ 1²

⇒ 1

Then the value of the expression A, B, C, and D will be 1, ∞, ∞, and 1.

Find the equation of the exponential function represented by the table below:

Answers

Answer:

y = 0.2(0.5)^x

Step-by-step explanation:

Exponential function are of the form

y = ab^x

----------------------

To find "a" plug in x = 0 y = 0.2

0.2 = a(0.2)^0

0.2 = a

-------------------------

To find "b" plug in another point and a = 0.2

using x = 2, b = 0.05

0.05 = 0.2b^2

Divide both sides by 0.20

.25 = b^2

Take the square root of both sides

0.5 = b

-----------------------------

With a = 0.2 and b = 0.5 the equation becomes

y = 0.2(0.5)^x
