Answer:

A model with 4 shaded sections and 6 unshaded sections.

A model with 40 shaded sections and 60 unshaded sections.

Step-by-step explanation:

Required:

Which models shows 40%

(a) 4 shaded and 6 unshaded

First, we calculate the total sections

Total = 4 + 6

Total = 10

The percentage of the shaded section is:

Shaded = \frac{4}{10} * 100\%

Shaded = 0.4 * 100\%

Shaded = 40\%

(b) 40 shaded and 60 unshaded

First, we calculate the total sections

Total = 40 + 60

Total = 100

The percentage of the shaded section is:

Shaded = \frac{40}{100} * 100\%

Shaded = 0.4 * 100\%

Shaded = 40\%

(c) 2 shaded and 8 unshaded

First, we calculate the total sections

Total = 2 + 8

Total = 10

The percentage of the shaded section is:

Shaded = \frac{2}{10} * 100\%

Shaded = 0.2 * 100\%

Shaded = 20\%

<em>Hence, (a) and (b) shows 40%</em>

Find an antiderivative F(x) with F′(x) = f(x) = 6 + 24x^3 + 18x^5 and F(1)=0.
7nadin3 [17]

Answer:

The antiderivative is F(X) = 6x + 6x^4 + 3x^6 - 15.

Step-by-step explanation:

Antiderivative F(x)

This is the integral of F^{\prime}(x)

So

F′(x) = f(x) = 6 + 24x^3 + 18x^5

Then:

F(x) = \int (6 + 24x^3 + 18x^5) dx

F(x) = 6x + \frac{24x^4}{4} + \frac{18x^6}{6} + K

F(x) = 6x + 6x^4 + 3x^6 + K

F(1)=0

F(X) = 0 when x = 1. We use this to find K.

F(x) = 6x + 6x^4 + 3x^6 + K

0 = 6 + 6 + 3 + K

K = -15

Thus

The antiderivative is F(X) = 6x + 6x^4 + 3x^6 - 15.

PLEASE HURRY WILL MARK BRAINIEST THIS IS AN EASY QUESTION
viva [34]

first qn

4/36=1/9

total no. of ways to roll a dice=36

no. of ways to produce 7=3

(1+6=7, 2+5=7, 3+4=7)

no. of ways to produce 11=1

(5+6=11)

there are 4 ways in total. 4/36 simplify it to be 1/9

second qn im not sure but i think its

1/9 x 50 = 50/9 = 5 x (5/9)

round it off to the smaller whole no. which is 5 so i think its 5 times in 50 trials
