<u><em>Answer:</em></u>

a. He will have to read half an article per night

b. Fraction of the reading assignment read each night = \frac{0.5}{4}=\frac{1}{8}

<u><em>Explanation:</em></u>

<u>Part a:</u>

<u>We are given that:</u>

number of articles to read = 4 articles

number of nights = 8 nights

To get the number of articles that he should read per night, we will simply divide the the number of articles by the number of nights

<u>Therefore:</u>

number of articles to read per night = \frac{4}{8}=\frac{1}{2} articles per night

<u>Part b:</u>

Now, we know that he will read half an article each night from a total of 4 articles

To get the fraction of the reading assignment read each night, we will divide the number of articles read each night by the total number of assignments

<u>Therefore:</u>

Fraction of the reading assignment read each night = \frac{0.5}{4}=\frac{1}{8}

Hope this helps :)

7. The diagram shows a regular pentagon inscribed inside the rectangle. Find the values of x, y, and z.
Wewaii [24]
<span>regular pentagon sum of interior = (5 - 2) x 180 = 3 x 180 = 540
so
x = 540 / 5 = 108

180 - 108 = 72
y = 72/2 = 36

z = 180 - 90 - 36
z = 54

answer
x = 108, y = 36 and z = 54</span>

Answer:

Pie Chart

Step-by-step explanation:

The variable mentioned in this case is categorical. That is, it has no numerical value, and can only be put into categories.

Some of the basic rule In statistics to represent data using charts are as follows:

• For categorical variables (nominal/ordinal) variables, use pie charts and bar charts

• For interval/ratio variables, use histograms

A pie chart is a circular chart divided into wedge-like portions and is basically used to display percentage or proportion of categories in the data The percentage represented by each category is shown by the corresponding slice/portion of the whole pie.

A population of mice is increasing exponentially. On Monday there were 120 mice. One month later there were 132 mice. Write a fu
den301095 [7]

Answer:

y =120*1.1^x

r = 10\% --- Percentage increase

Step-by-step explanation:

Given

Let

x \to months

y \to mice

So, we have:

(x_1,y_1) = (0,120) --- Monday

(x_2,y_2) = (1,132) --- One month later

Required

The function

The function is represented as:

y = ab^x

In (x_1,y_1) = (0,120), we have:

120 =a * 1

120 =a

Rewrite as:

a = 120

In (x_2,y_2) = (1,132), we have:

132 = a * b^1

132 = a * b

Substitute a = 120

132 = 120 * b

Solve for b

b = \frac{132}{120}

b = 1.1

Recall that:

y = ab^x

Hence, the function is:

y =120*1.1^x

To get the monthly percentage increase (r), we have:

y = a(1 + r)^x

Compare to: y = ab^x

So:

1+r =b

Make r the subject

r = b-1

r = 1.1-1

r = 0.1

Express as percentage

r = 0.1*100\%

r = 10\%

What is -x+y +2x+y ?
Trava [24]

The answer would be: x+2y

First, combine the like terms.

-x and 2x

Now your equation looks like this:

x+y+y

Now combine the y like terms.

y and y and you get 2y

Then you are left with your answer: x+2y

Hope this helps! :3
