Answer:

15/44

Step-by-step explanation:

Add 600, 450, and 270 for a total of 1320. This is the entire circle.

450/1320 is equal to 15/44. I got this by dividing both 450 and 1320 by their GCF which is 30.

Luda [366]

Answer:

54% probability that a person likes Italian food, but not Chinese food.

82% probaility that a person likes at least one of these foods

79% proability that a person likes at most one of these foods

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a person likes Italian food.

B is the probability that a person likes Chinese food.

We have that:

$A = a + (A \cap B)$

In which a is the probability that a person likes Italian food but not Chinese and $A \cap B$ is the probability that a person likes both Italian and Chinese food.

By the same logic, we have that:

$B = b + (A \cap B)$

The probability that a person likes both foods is 0.21.

This means that $A \cap B = 0.21$

The probability that a person likes Chinese food is 0.28

This means that $B = 0.28$

$B = b + (A \cap B)$

$0.28 = b + 0.21$

$b = 0.07$

The probability that a person likes Italian food is 0.75

This means that $A = 0.75$

$A = a + (A \cap B)$

$0.75 = a + 0.21$

$a = 0.54$

Determine the probability that a person likes Italian, but not Chinese

This is a.

54% probability that a person likes Italian food, but not Chinese food.

Determine the probaility that a person likes at least one of these foods

$P = a + b + (A \cap B) = 0.54 + 0.07 + 0.21 = 0.82$

82% probaility that a person likes at least one of these foods

Determine the proability that a person likes at most one of these foods

Either a person likes at most one of these foods, or it likes both. The sum of the probabilities of these events is decimal 1.

0.21 probability it likes both.

Then

0.21 + p = 1

p = 0.79

79% proability that a person likes at most one of these foods

? Question

kari74 [83]

Answer:

Please find attached , the filled in boxes

The y-intercept is (0, 4)

Step-by-step explanation:

The given function is g(x) = $4 \times (0.6)^x$

The values of x are given as -10, -1, 0, 1, 2, 8

The values of g(x) are

g(-10) = 4 × 0.6⁽⁻¹⁰⁾ = 4 × (3/5)⁽⁻¹⁰⁾ = 4 × (5/3)⁽¹⁰⁾ = 661.53

g(-1) = 4 × 0.6⁽⁻¹⁾ = 4 × (3/5)⁽⁻¹⁾ = 4 × (5/3)⁽⁽¹⁾ = 20/3 =

g(0) = 4 × 0.6⁽⁰⁾ = 4 × (3/5)⁽⁰⁾ = 4 × 1 = 4

g(1) = 4 × 0.6⁽¹⁾ = 4 × (3/5)⁽¹⁾ = 12/5 = 2.4

g(2) = 4 × 0.6⁽²⁾ = 4 × (3/5)⁽²⁾ = 36/25 = 1.44

g(8) = 4 × 0.6⁽⁸⁾ = 4 × (3/5)⁽⁸⁾ = 0.0672

The y intercept is given at the point x = 0 which is g(0) = 4

The y-intercept is g(0) = 4

PLEASE HELP 40 POINTS

iris [78.8K]

Answer:

Option 4

Step-by-step explanation:

Term = n/(4^n)

(n+1)th term = (n+1)/[4^(n+1)]

Ratio: (n+1)/[4^(n+1)] ÷ n/(4^n)

= (n+1)/[4^(n+1)] × (4^n)/n

= [(n+1)/n] × (1/4)

For large n, (n+1)/n approaches 1

[(n+1)/n] × (1/4) approaches 1/4 which is less than 1

Since the ratio is less than 1, series converges

Given:

The inequality is:

$y>5x+3$

To find:

The y-intercept, slope and type of line (solid or dotted).

Solution:

The slope intercept form of a line is:

$y=mx+b$ ...(i)

Where, m is the slope and b is the y-intercept.

We have,

$y>5x+3$

The relation equation is:

$y=5x+3$ ...(ii)

On comparing (i) and (ii), we get

$m=5$

$b=3$

It means the slope is 5 and the y-intercept is 3.

The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.

Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.
